• Excessive denied requests for port 58322 in syslog

  - by Nathan C.

  My iptables is setup to block all unneeded ports as it should but I'm checking my syslog due to these random but all-to-frequent apache2 crashes and I noticed a lot of requests such as this. In all the archived syslogs that I have these are present from different IP addresses. There is a similar question with an accepted here: What service uses UDP port 60059?

• Combining Shared Secret and Certificates

  - by Michael Stephenson

  As discussed in the introduction article this walkthrough will explain how you can implement WCF security with the Windows Azure Service Bus to ensure that you can protect your endpoint in the cloud with a shared secret but also combine this with certificates so that you can identify the sender of the message.   Prerequisites As in the previous article before going into the walk through I want to explain a few assumptions about the scenario we are implementing but to keep the article shorter I am not going to walk through all of the steps in how to setup some of this. In the solution we have a simple console application which will represent the client application. There is also the services WCF application which contains the WCF service we will expose via the Windows Azure Service Bus. The WCF Service application in this example was hosted in IIS 7 on Windows 2008 R2 with AppFabric Server installed and configured to auto-start the WCF listening services. I am not going to go through significant detail around the IIS setup because it should not matter in relation to this article however if you want to understand more about how to configure WCF and IIS for such a scenario please refer to the following paper which goes into a lot of detail about how to configure this. The link is: http://tinyurl.com/8s5nwrz   Setting up the Certificates To keep the post and sample simple I am going to use the local computer store for all certificates but this bit is really just the same as setting up certificates for an example where you are using WCF without using Windows Azure Service Bus. In the sample I have included two batch files which you can use to create the sample certificates or remove them. Basically you will end up with: A certificate called PocServerCert in the personal store for the local computer which will be used by the WCF Service component A certificate called PocClientCert in the personal store for the local computer which will be used by the client application A root certificate in the Root store called PocRootCA with its associated revocation list which is the root from which the client and server certificates were created   For the sample Im just using development certificates like you would normally, and you can see exactly how these are configured and placed in the stores from the batch files in the solution using makecert and certmgr.   The Service Component To begin with let's look at the service component and how it can be configured to listen to the service bus using a shared secret but to also accept a username token from the client. In the sample the service component is called Acme.Azure.ServiceBus.Poc.Cert.Services. It has a single service which is the Visual Studio template for a WCF service when you add a new WCF Service Application so we have a service called Service1 with its Echo method. Nothing special so far!.... The next step is to look at the web.config file to see how we have configured the WCF service. In the services section of the WCF configuration you can see I have created my service and I have created a local endpoint which I simply used to do a little bit of diagnostics and to check it was working, but more importantly there is the Windows Azure endpoint which is using the ws2007HttpRelayBinding (note that this should also work just the same if your using netTcpRelayBinding). The key points to note on the above picture are the service behavior called MyServiceBehaviour and the service bus endpoints behavior called MyEndpointBehaviour. We will go into these in more detail later.   The Relay Binding The relay binding for the service has been configured to use the TransportWithMessageCredential security mode. This is the important bit where the transport security really relates to the interaction between the service and listening to the Azure Service Bus and the message credential is where we will use our certificate like we have specified in the message/clientCrentialType attribute. Note also that we have left the relayClientAuthenticationType set to RelayAccessToken. This means that authentication will be made against ACS for accessing the service bus and messages will not be accepted from any sender who has not been authenticated by ACS.   The Endpoint Behaviour In the below picture you can see the endpoint behavior which is configured to use the shared secret client credential for accessing the service bus and also for diagnostic purposes I have included the service registry element.     Hopefully if you are familiar with using Windows Azure Service Bus relay feature the above is very familiar to you and this is a very common setup for this section. There is nothing specific to the username token implementation here. The Service Behaviour Now we come to the bit with most of the certificate stuff in it. When you configure the service behavior I have included the serviceCredentials element and then setup to use the clientCertificate check and also specifying the serviceCertificate with information on how to find the servers certificate in the store.     I have also added a serviceAuthorization section where I will implement my own authorization component to perform additional security checks after the service has validated that the message was signed with a good certificate. I also have the same serviceSecurityAudit configuration to log access to my service. My Authorization Manager The below picture shows you implementation of my authorization manager. WCF will eventually hand off the message to my authorization component before it calls the service code. This is where I can perform some logic to check if the identity is allowed to access resources. In this case I am simple rejecting messages from anyone except the PocClientCertificate.     The Client Now let's take a look at the client side of this solution and how we can configure the client to authenticate against ACS but also send a certificate over to the service component so it can implement additional security checks on-premise. I have a console application and in the program class I want to use the proxy generated with Add Service Reference to send a message via the Azure Service Bus. You can see in my WCF client configuration below I have setup my details for the azure service bus url and am using the ws2007HttpRelayBinding.   Next is my configuration for the relay binding. You can see below I have configured security to use TransportWithMessageCredential so we will flow the token from a certificate with the message and also the RelayAccessToken relayClientAuthenticationType which means the component will validate against ACS before being allowed to access the relay endpoint to send a message.     After the binding we need to configure the endpoint behavior like in the below picture. This contains the normal transportClientEndpointBehaviour to setup the ACS shared secret configuration but we have also configured the clientCertificate to look for the PocClientCert.     Finally below we have the code of the client in the console application which will call the service bus. You can see that we have created our proxy and then made a normal call to a WCF in exactly the normal way but the configuration will jump in and ensure that a token is passed representing the client certificate.     Conclusion As you can see from the above walkthrough it is not too difficult to configure a service to use both a shared secret and certificate based token at the same time. This gives you the power and protection offered by the access control service in the cloud but also the ability to flow additional tokens to the on-premise component for additional security features to be implemented.

• Pushing DNSSEC updates with offline keys

  - by eggyal

  In a non-professional capacity, I look after the DNS of some 18 domains: mostly personal/vanity domains for immediate family. I outsource the whole shebang to an inexpensive managed hosting provider with a web interface through which I manage the zones; since the provider also offers DNSSEC, I have successfully deployed that too. These domains are so unimportant that an attack targetted against them seems much less likely than a general compromise of my provider's systems, at which point the records of all their customers might be changed to misdirect traffic (perhaps with extremely long TTLs). DNSSEC could protect against such an attack, but only if the zone's private keys are not held by the hosting provider. So, I wonder: how can one keep DNSSEC private keys offline yet still transfer signed zones to an outsourced DNS host? The most obvious answer (to me, at least) is to run one's own shadow/hidden master (from which the provider can slave) and then copy offline-signed zonefiles to the master as required. The problem is that the only machine I (want to*) control is my personal laptop, which usually connects from a typical home ADSL (behind NAT over a dynamically-assigned IP address). Having them slave from that (e.g. with a very long Expiry time on the zone for periods when my laptop is offline/unavailable) would not only require a Dynamic DNS record from which they can slave (if indeed they can slave from a named host rather than a static IP address), but would also involve me running a DNS server on my laptop and opening both it and my home network up to the incoming zone transfer requests: not ideal. I would prefer a much more push-oriented design, whereby my laptop initiates transfer of offline-signed zonefiles/updates to the provider's servers. I looked into whether nsupdate could fit the bill: documentation is a little sketchy, but my testing (with BIND 9.7) suggests it can indeed update DNSSEC zones, but only where the server holds the keys to perform the zone signing; I have not found a way to have it take an update including the relevant RRSIG/NSEC/etc. records and have the server accept them. Is this a supported use-case? If not, I suspect the only solutions which could fit the bill will involve non-DNS-based transfer of the zone updates and would welcome recommendations that are supported by (hopefully inexpensive) hosting providers: SFTP/SCP? rsync? RDBMS replication? Proprietary API? Finally, what would be the practical implications of such a setup? Key rotation is jumping out at me as being an obvious difficulty, especially if my laptop is offline for extended periods. But the zones are extremely stable, so perhaps I could get away with long-lived ZSKs**...? * Whilst I could run a shadow/hidden master on e.g. an outsourced VPS, I dislike the overhead of having to secure / manage / monitor / maintain yet another system; not to mention the additional financial costs of so doing. ** Okay, this would enable a concerted attacker to replay outdated records—but the risk and impact of such are both tolerable in the case of these domains.

• /phpTest/zologize/axa.php? Another botnet?

  - by M132

  Starring at the log made me think, what is /phpTest/zologize/axa.php and why are bots looking for it? Previously, I had lots of /HNAP1/ requests. Requesting /HNAP1/ from IPs from log revealed, that all of them were sent by Linksys routers. 3 months later, these requests turned out to be generated by a router worm called TheMoon. But requesting /phpTest/zologize/axa.php from these servers returns a 404 error.

• amplified reflected attack on dns

  The term is new to me. So I have a few questions about it. I've heard it mostly happens with DNS servers? How do you protect against it? How do you know if your servers can be used as a victim? This is a configuration issue right? my named conf file include "/etc/rndc.key"; controls { inet 127.0.0.1 allow { localhost; } keys { "rndc-key"; }; }; options { /* make named use port 53 for the source of all queries, to allow * firewalls to block all ports except 53: */ // query-source port 53; /* We no longer enable this by default as the dns posion exploit has forced many providers to open up their firewalls a bit */ // Put files that named is allowed to write in the data/ directory: directory "/var/named"; // the default pid-file "/var/run/named/named.pid"; dump-file "data/cache_dump.db"; statistics-file "data/named_stats.txt"; /* memstatistics-file "data/named_mem_stats.txt"; */ allow-transfer {"none";}; }; logging { /* If you want to enable debugging, eg. using the 'rndc trace' command, * named will try to write the 'named.run' file in the $directory (/var/named"). * By default, SELinux policy does not allow named to modify the /var/named" directory, * so put the default debug log file in data/ : */ channel default_debug { file "data/named.run"; severity dynamic; }; }; view "localhost_resolver" { /* This view sets up named to be a localhost resolver ( caching only nameserver ). * If all you want is a caching-only nameserver, then you need only define this view: */ match-clients { 127.0.0.0/24; }; match-destinations { localhost; }; recursion yes; zone "."

• Is this valid JFS partition?

  - by Coolmax

  This is my first question on StackExchange. My teacher gave my his laptop (with Fedora 16 on it) and compact flash card with data. He want to have access to files on card, but he couldn't get access to it. The problem is Linux don't know what type of partion is. I suppose there is JFS: root@debian:~# dmesg |grep sdc [ 9066.908223] sd 3:0:0:1: [sdc] 3940272 512-byte logical blocks: (2.01 GB/1.87 GiB) [ 9066.962307] sd 3:0:0:1: [sdc] Write Protect is off [ 9066.962310] sd 3:0:0:1: [sdc] Mode Sense: 03 00 00 00 [ 9066.962312] sd 3:0:0:1: [sdc] Assuming drive cache: write through [ 9067.028420] sd 3:0:0:1: [sdc] Assuming drive cache: write through [ 9067.028637] sdc: unknown partition table [ 9067.097065] sd 3:0:0:1: [sdc] Assuming drive cache: write through [ 9067.097281] sd 3:0:0:1: [sdc] Attached SCSI removable disk and some of data: root@debian:~# hexdump -Cn 65536 /dev/sdc 00000000 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00008000 4a 46 53 31 01 00 00 00 48 63 0e 00 00 00 00 00 |JFS1....Hc......| 00008010 00 10 00 00 0c 00 03 00 00 02 00 00 09 00 00 00 |................| 00008020 00 20 00 00 00 09 20 10 02 00 00 00 00 00 00 00 |. .... .........| 00008030 04 00 00 00 26 00 00 00 02 00 00 00 24 00 00 00 |....&.......$...| 00008040 41 03 00 00 16 00 00 00 00 02 00 00 a0 cc 01 00 |A...............| 00008050 37 00 00 00 69 cc 01 00 b6 d8 ac 4b 00 00 00 00 |7...i......K....| 00008060 32 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 |2...............| 00008070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00008080 00 00 00 00 00 00 00 00 90 15 e5 5f e3 c4 45 fa |..........._..E.| 00008090 9d 6a 5c b5 4f da 62 1a 00 00 00 00 00 00 00 00 |.j\.O.b.........| 000080a0 00 00 00 00 00 00 00 00 c3 c9 01 00 ed 81 00 00 |................| 000080b0 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 000080c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * [cut] * 0000f000 4a 46 53 31 01 00 00 00 48 63 0e 00 00 00 00 00 |JFS1....Hc......| 0000f010 00 10 00 00 0c 00 03 00 00 02 00 00 09 00 00 00 |................| 0000f020 00 20 00 00 00 09 20 10 00 00 00 00 00 00 00 00 |. .... .........| 0000f030 04 00 00 00 26 00 00 00 02 00 00 00 24 00 00 00 |....&.......$...| 0000f040 41 03 00 00 16 00 00 00 00 02 00 00 a0 cc 01 00 |A...............| 0000f050 37 00 00 00 69 cc 01 00 b6 d8 ac 4b 00 00 00 00 |7...i......K....| 0000f060 32 00 00 00 02 00 00 00 00 00 00 00 00 00 00 00 |2...............| 0000f070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 0000f080 00 00 00 00 00 00 00 00 90 15 e5 5f e3 c4 45 fa |..........._..E.| 0000f090 9d 6a 5c b5 4f da 62 1a 00 00 00 00 00 00 00 00 |.j\.O.b.........| 0000f0a0 00 00 00 00 00 00 00 00 c3 c9 01 00 ed 81 00 00 |................| 0000f0b0 01 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| 0000f0c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00010000 I'm total newbie to filesystems.

And sorry for my bad english :) Kind regards.

• The best dvd ripper software in 2014 review

  - by user328170

  The top 3 DVD Ripping Tools in 2014 Nowadays everyone may have several smart mobile devices, such as iphone, ipad air, ipad mini ,Samsung Galaxy and Sony Xperia. If you want to take your movies with your mobile devices, or sometimes just want to backup those classic physical discs on your notebook or workstation with high quality resolutions, you need a fast and stable software to rip them and convert them to the format you like. Fortunately, there are plenty of great software products designed to make the process easy and transform DVD to the files that are playable on any mobile device you choose. We have done a full review on dozens of products. Here are five of the best, based on our review. We test the software from its ripping speed, friendly use guide , reliability and ripping capability. The top one is still Winx DVD Ripper platinum. We've test its 6.1 version 2 years ago for its ability to quickly and easily rip DVDs and Blu-ray discs to high quality MKV files with a single click. It gave us deep impression in the test. This time we test it’s lastest 7.3.5 version. Besides easy use and speed, we test its capability to decrypt all kinds of discs with different protect method, for example, Disney X-project DRM , Sony ArccOS, RCE and region code. The result shows that winx dvd ripper platinum still maintain its advantages in all the area. Winx dvd ripper platinum is a more focused on DVD ripping software with the basic duty to rip and convert DVD. The color of UI is a modern technical sense. All the main functions are shown obviously while others specials are hidden for advanced users, making it more clear and convenient to make option. There are two company weisoft limited and Digiarty who can provide the software. Weisoft limited focus on USA, UK and Australia market. Digiarty focus on others. ripping speed ????? friendly use guide ????? reliability ????? ripping capability ????? The second one DVDFab DVDFab is also very robust during ripping dics. It can also decrypt most of the dics in the market. The shortage it still friendly use and speed. We'd note that the app is frequently updated to cut through the copy protection on even the latest DVDs and Blu-ray discs . The app is shareware, meaning most features are free, including decrypting and ripping to your hard drive. Many of you note that you use another app for compression and authoring, but many of you say they hey, storage is cheap, and the rips from DVDFab are easy, one-click, and work. ripping speed ??? friendly use guide ???? reliability ????? ripping capability ????? The Third one is Handbrake Handbrake is our favorite video encoder for a reason: it's simple, easy to use, easy to install, and offers a lots of options to get the high quality file as a result. If you're scared by them, you don't even have to use them—the app will compensate for you and pick some settings it thinks you'll like based on your destination device. So many of you like Handbrake that many of you use it in conjunction with another app (like VLC, which makes ripping easy)—you'll let another app do the rip and crack the DRM on your discs, and then process the file through Handbrake for encoding. The app is fast, can make the most of multi-core processors to speed up the process, and is completely open source. ripping speed ??? friendly use guide ???? reliability ???? ripping capability ????

• Active Directory Password Policy Problem

  - by Will

  To Clarify: my question is why isn't my password policy applying to people in the domain. Hey guys, having trouble with our password policy in Active Directory. Sometimes it just helps me to type out what I’m seeing It appears to not be applying properly across the board. I am new to this environment and AD in general but I think I have a general grasp of what should be going on. It’s a pretty simple AD setup without too many Group Policies being applied. It looks something like this DOMAIN Default Domain Policy (link enabled) Password Policy (link enabled and enforce) Personal OU Force Password Change (completely empty nothing in this GPO) IT OU Lockout Policy (link enabled and enforced) CS OU Lockout Policy Accouting OU Lockout Policy The password policy and default domain policy both define the same things under Computer ConfigWindows seetings sec settings Account Policies / Password Policy Enforce password History : 24 passwords remembered Maximum Password age : 180 days Min password age: 14 days Minimum Password Length: 6 characters Password must meet complexity requirements: Enabled Store Passwords using reversible encryption: Disabled Account Policies / Account Lockout Policy Account Lockout Duration 10080 Minutes Account Lockout Threshold: 5 invalid login attempts Reset Account Lockout Counter after : 30 minutes IT lockout This just sets the screen saver settings to lock computers when the user is Idle. After running Group Policy modeling it seems like the password policy and default domain policy is getting applied to everyone. Here is the results of group policy modeling on MO-BLANCKM using the mblanck account, as you can see the policies are both being applied , with nothing important being denied Group Policy Results NCLGS\mblanck on NCLGS\MO-BLANCKM Data collected on: 12/29/2010 11:29:44 AM Summary Computer Configuration Summary General Computer name NCLGS\MO-BLANCKM Domain NCLGS.local Site Default-First-Site-Name Last time Group Policy was processed 12/29/2010 10:17:58 AM Group Policy Objects Applied GPOs Name Link Location Revision Default Domain Policy NCLGS.local AD (15), Sysvol (15) WSUS-52010 NCLGS.local/WSUS/Clients AD (54), Sysvol (54) Password Policy NCLGS.local AD (58), Sysvol (58) Denied GPOs Name Link Location Reason Denied Local Group Policy Local Empty Security Group Membership when Group Policy was applied BUILTIN\Administrators Everyone S-1-5-21-507921405-1326574676-682003330-1003 BUILTIN\Users NT AUTHORITY\NETWORK NT AUTHORITY\Authenticated Users NCLGS\MO-BLANCKM$ NCLGS\Admin-ComputerAccounts-GP NCLGS\Domain Computers WMI Filters Name Value Reference GPO(s) None Component Status Component Name Status Last Process Time Group Policy Infrastructure Success 12/29/2010 10:17:59 AM EFS recovery Success (no data) 10/28/2010 9:10:34 AM Registry Success 10/28/2010 9:10:32 AM Security Success 10/28/2010 9:10:34 AM User Configuration Summary General User name NCLGS\mblanck Domain NCLGS.local Last time Group Policy was processed 12/29/2010 11:28:56 AM Group Policy Objects Applied GPOs Name Link Location Revision Default Domain Policy NCLGS.local AD (7), Sysvol (7) IT-Lockout NCLGS.local/Personal/CS AD (11), Sysvol (11) Password Policy NCLGS.local AD (5), Sysvol (5) Denied GPOs Name Link Location Reason Denied Local Group Policy Local Empty Force Password Change NCLGS.local/Personal Empty Security Group Membership when Group Policy was applied NCLGS\Domain Users Everyone BUILTIN\Administrators BUILTIN\Users NT AUTHORITY\INTERACTIVE NT AUTHORITY\Authenticated Users LOCAL NCLGS\MissingSkidEmail NCLGS\Customer_Service NCLGS\Email_Archive NCLGS\Job Ticket Users NCLGS\Office Staff NCLGS\CUSTOMER SERVI-1 NCLGS\Prestige_Jobs_Email NCLGS\Telecommuters NCLGS\Everyone - NCL WMI Filters Name Value Reference GPO(s) None Component Status Component Name Status Last Process Time Group Policy Infrastructure Success 12/29/2010 11:28:56 AM Registry Success 12/20/2010 12:05:51 PM Scripts Success 10/13/2010 10:38:40 AM Computer Configuration Windows Settings Security Settings Account Policies/Password Policy Policy Setting Winning GPO Enforce password history 24 passwords remembered Password Policy Maximum password age 180 days Password Policy Minimum password age 14 days Password Policy Minimum password length 6 characters Password Policy Password must meet complexity requirements Enabled Password Policy Store passwords using reversible encryption Disabled Password Policy Account Policies/Account Lockout Policy Policy Setting Winning GPO Account lockout duration 10080 minutes Password Policy Account lockout threshold 5 invalid logon attempts Password Policy Reset account lockout counter after 30 minutes Password Policy Local Policies/Security Options Network Security Policy Setting Winning GPO Network security: Force logoff when logon hours expire Enabled Default Domain Policy Public Key Policies/Autoenrollment Settings Policy Setting Winning GPO Enroll certificates automatically Enabled [Default setting] Renew expired certificates, update pending certificates, and remove revoked certificates Disabled Update certificates that use certificate templates Disabled Public Key Policies/Encrypting File System Properties Winning GPO [Default setting] Policy Setting Allow users to encrypt files using Encrypting File System (EFS) Enabled Certificates Issued To Issued By Expiration Date Intended Purposes Winning GPO SBurns SBurns 12/13/2007 5:24:30 PM File Recovery Default Domain Policy For additional information about individual settings, launch Group Policy Object Editor.

• FreeBSD high load loopback interface

  - by user1740915

  I have a problem with a FreeBSD server. There is a FreeBSD 9.0 amd64, two network cards em1 (internet), em0 (local network) configured firewall ipfw, natd, squid (not transparent), the server acts as a gateway for access to the Internet. Next problem: upload via squid is very low. At this moment I see next: natd, dhcpd load the cpu at that time when uploading through squid and there are a lot of traffic through the loopback interface. ipfw show output 0100 655389684 36707144666 allow ip from any to any via lo0 00200 0 0 deny ip from any to 127.0.0.0/8 00300 0 0 deny ip from 127.0.0.0/8 to any 00400 0 0 deny ip from any to ::1 00500 0 0 deny ip from ::1 to any 00600 4 292 allow ipv6-icmp from :: to ff02::/16 00700 0 0 allow ipv6-icmp from fe80::/10 to fe80::/10 00800 1 76 allow ipv6-icmp from fe80::/10 to ff02::/16 00900 0 0 allow ipv6-icmp from any to any ip6 icmp6types 1 01000 0 0 allow ipv6-icmp from any to any ip6 icmp6types 2,135,136 01100 1615 76160 deny ip from 192.168.1.1 to any in via em1 01200 0 0 deny ip from 199.69.99.11 to any in via em0 01300 46652 3705426 deny ip from any to 172.16.0.0/12 via em1 01400 3936404 345618870 deny ip from any to 192.168.0.0/16 via em1 01500 4 336 deny ip from any to 0.0.0.0/8 via em1 01600 4129 387621 deny ip from any to 169.254.0.0/16 via em1 01700 0 0 deny ip from any to 192.0.2.0/24 via em1 01800 917566 33777571 deny ip from any to 224.0.0.0/4 via em1 01900 147872 22029252 deny ip from any to 240.0.0.0/4 via em1 02000 1132194739 1190981955947 divert 8668 ip4 from any to any via em1 02100 3 248 deny ip from 172.16.0.0/12 to any via em1 02200 35925 2281289 deny ip from 192.168.0.0/16 to any via em1 02300 1808 122494 deny ip from 0.0.0.0/8 to any via em1 02400 3 174 deny ip from 169.254.0.0/16 to any via em1 02500 0 0 deny ip from 192.0.2.0/24 to any via em1 02600 0 0 deny ip from 224.0.0.0/4 to any via em1 02700 0 0 deny ip from 240.0.0.0/4 to any via em1 02800 960156249 1095316736582 allow tcp from any to any established 02900 64236062 8243196577 allow ip from any to any frag 03000 34 1756 allow tcp from any to me dst-port 25 setup 03100 193 11580 allow tcp from any to me dst-port 53 setup 03200 63 4222 allow udp from any to me dst-port 53 03300 64 8350 allow udp from me 53 to any 03400 417 24140 allow tcp from any to me dst-port 80 setup 03500 211 10472 allow ip from any to me dst-port 3389 setup 05300 77 4488 allow ip from any to me dst-port 1723 setup 05400 3 156 allow ip from any to me dst-port 8443 setup 05500 9882 590596 allow tcp from any to me dst-port 22 setup 05600 1 60 allow ip from any to me dst-port 2000 setup 05700 0 0 allow ip from any to me dst-port 2201 setup 07400 4241779 216690096 deny log logamount 1000 ip4 from any to any in via em1 setup proto tcp 07500 21135656 1048824936 allow tcp from any to any setup 07600 474447 35298081 allow udp from me to any dst-port 53 keep-state 07700 532 40612 allow udp from me to any dst-port 123 keep-state 65535 1990638432 1122305322718 allow ip from any to any systat -ifstat when uploading via squid Load Average ||| Interface Traffic Peak Total tun0 in 79.507 KB/s 232.479 KB/s 42.314 GB out 2.022 MB/s 2.424 MB/s 59.662 GB lo0 in 4.450 MB/s 4.450 MB/s 43.723 GB out 4.450 MB/s 4.450 MB/s 43.723 GB em1 in 2.629 MB/s 2.982 MB/s 464.533 GB out 2.493 MB/s 2.875 MB/s 484.673 GB em0 in 240.458 KB/s 296.941 KB/s 442.368 GB out 512.508 KB/s 850.857 KB/s 416.122 GB top output PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND 66885 root 1 92 0 26672K 2784K CPU3 3 528:43 65.48% natd 9160 dhcpd 1 45 0 31032K 9280K CPU1 1 7:40 32.96% dhcpd 66455 root 1 20 0 18344K 2856K select 1 119:27 1.37% openvpn 16043 squid 1 20 0 44404K 17884K kqread 2 0:22 0.29% squid squid.conf cat /usr/local/etc/squid/squid.conf #

• MySQL port 3306 blocked in csf yet can still telnet to port 3306 from external host

  - by Neek

  We have a Centos 6 VPS that was recently migrated to a new machine within the same web hosting company. It's running WHM/cPanel and has csf/lfd installed. csf is set up with mostly vanilla config. I'm no iptables expert, csf has not let me down before. If a port isn't in the TCP_IN list, it should be blocked on the firewall by iptables. My problem is that I can telnet to port 3306 from an external host, yet I think iptables ought to be blocking 3306 because of csf's rules. We are now failing a security check because of this open port. (this output is obfuscated to protect the innocent: www.ourhost.com is the host with the firewall problem) [root@nickfenwick log]# telnet www.ourhost.com 3306 Trying 158.255.45.107... Connected to www.ourhost.com. Escape character is '^]'. HHost 'nickfenwick.com' is not allowed to connect to this MySQL serverConnection closed by foreign host. So the connection is established, and MySQL refuses the connection due to its configuration. I need the network connection to be refused at the firewall level, before it reaches MySQL. Using WHM's csf web UI I can see 'Firewall Configuration' includes a fairly sensible TCP_IN line: TCP_IN: 20,21,22,25,53,80,110,143,222,443,465,587,993,995,2077,2078,2082,2083,2086,2087,2095,2096,8080 (lets ignore that I could trim that a little for now, my concern is that 3306 is not listed in that list) When csf is restarted it logs the usual slew of output as it sets up iptables rules, for example what looks like it blocking all traffic and then allowing specific ports like SSH on 22: [cut] DROP all opt -- in * out * 0.0.0.0/0 -> 0.0.0.0/0 [cut] ACCEPT tcp opt -- in !lo out * 0.0.0.0/0 -> 0.0.0.0/0 state NEW tcp dpt:22 [cut] I can see that iptables is running, service iptables status returns a long list of firewall rules. Here is my Chain INPUT section from service iptables status, hopefully that's enough to show how the firewall is configured.

• OpenVPN (HideMyAss) client on Ubuntu: Route only HTTP traffic

  - by Andersmith

  I want to use HideMyAss VPN (hidemyass.com) on Ubuntu Linux to route only HTTP (ports 80 & 443) traffic to the HideMyAss VPN server, and leave all the other traffic (MySQL, SSH, etc.) alone. I'm running Ubuntu on AWS EC2 instances. The problem is that when I try and run the default HMA script, I suddenly can't SSH into the Ubuntu instance anymore and have to reboot it from the AWS console. I suspect the Ubuntu instance will also have trouble connecting to the RDS MySQL database, but haven't confirmed it. HMA uses OpenVPN like this: sudo openvpn client.cfg The client configuration file (client.cfg) looks like this: ############################################## # Sample client-side OpenVPN 2.0 config file # # for connecting to multi-client server. # # # # This configuration can be used by multiple # # clients, however each client should have # # its own cert and key files. # # # # On Windows, you might want to rename this # # file so it has a .ovpn extension # ############################################## # Specify that we are a client and that we # will be pulling certain config file directives # from the server. client auth-user-pass #management-query-passwords #management-hold # Disable management port for debugging port issues #management 127.0.0.1 13010 ping 5 ping-exit 30 # Use the same setting as you are using on # the server. # On most systems, the VPN will not function # unless you partially or fully disable # the firewall for the TUN/TAP interface. #;dev tap dev tun # Windows needs the TAP-Win32 adapter name # from the Network Connections panel # if you have more than one.

• e2fsck extremly slow, although enough memory exists

  - by kaefert

  I've got this external USB-Disk: kaefert@blechmobil:~$ lsusb -s 2:3 Bus 002 Device 003: ID 0bc2:3320 Seagate RSS LLC As can be seen in this dmesg output, there are some problems that prevents that disk from beeing mounted: kaefert@blechmobil:~$ dmesg | grep sdb [ 114.474342] sd 5:0:0:0: [sdb] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 114.475089] sd 5:0:0:0: [sdb] Write Protect is off [ 114.475092] sd 5:0:0:0: [sdb] Mode Sense: 43 00 00 00 [ 114.475959] sd 5:0:0:0: [sdb] Write cache: enabled, read cache: enabled, doesn't support DPO or FUA [ 114.477093] sd 5:0:0:0: [sdb] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 114.501649] sdb: sdb1 [ 114.502717] sd 5:0:0:0: [sdb] 732566645 4096-byte logical blocks: (3.00 TB/2.72 TiB) [ 114.504354] sd 5:0:0:0: [sdb] Attached SCSI disk [ 116.804408] EXT4-fs (sdb1): ext4_check_descriptors: Checksum for group 3976 failed (47397!=61519) [ 116.804413] EXT4-fs (sdb1): group descriptors corrupted! So I went and fired up my favorite partition manager - gparted, and told it to verify and repair the partition sdb1. This made gparted call e2fsck (version 1.42.4 (12-Jun-2012)) e2fsck -f -y -v /dev/sdb1 Although gparted called e2fsck with the "-v" option, sadly it doesn't show me the output of my e2fsck process (bugreport https://bugzilla.gnome.org/show_bug.cgi?id=467925 ) I started this whole thing on Sunday (2012-11-04_2200) evening, so about 48 hours ago, this is what htop says about it now (2012-11-06-1900): PID USER PRI NI VIRT RES SHR S CPU% MEM% TIME+ Command 3704 root 39 19 1560M 1166M 768 R 98.0 19.5 42h56:43 e2fsck -f -y -v /dev/sdb1 Now I found a few posts on the internet that discuss e2fsck running slow, for example: http://gparted-forum.surf4.info/viewtopic.php?id=13613 where they write that its a good idea to see if the disk is just that slow because maybe its damaged, and I think these outputs tell me that this is not the case in my case: kaefert@blechmobil:~$ sudo hdparm -tT /dev/sdb /dev/sdb: Timing cached reads: 3562 MB in 2.00 seconds = 1783.29 MB/sec Timing buffered disk reads: 82 MB in 3.01 seconds = 27.26 MB/sec kaefert@blechmobil:~$ sudo hdparm /dev/sdb /dev/sdb: multcount = 0 (off) readonly = 0 (off) readahead = 256 (on) geometry = 364801/255/63, sectors = 5860533160, start = 0 However, although I can read quickly from that disk, this disk speed doesn't seem to be used by e2fsck, considering tools like gkrellm or iotop or this: kaefert@blechmobil:~$ iostat -x Linux 3.2.0-2-amd64 (blechmobil) 2012-11-06 _x86_64_ (2 CPU) avg-cpu: %user %nice %system %iowait %steal %idle 14,24 47,81 14,63 0,95 0,00 22,37 Device: rrqm/s wrqm/s r/s w/s rkB/s wkB/s avgrq-sz avgqu-sz await r_await w_await svctm %util sda 0,59 8,29 2,42 5,14 43,17 160,17 53,75 0,30 39,80 8,72 54,42 3,95 2,99 sdb 137,54 5,48 9,23 0,20 587,07 22,73 129,35 0,07 7,70 7,51 16,18 2,17 2,04 Now I researched a little bit on how to find out what e2fsck is doing with all that processor time, and I found the tool strace, which gives me this: kaefert@blechmobil:~$ sudo strace -p3704 lseek(4, 41026998272, SEEK_SET) = 41026998272 write(4, "\212\354K[_\361\3nl\212\245\352\255jR\303\354\312Yv\334p\253r\217\265\3567\325\257\3766"..., 4096) = 4096 lseek(4, 48404766720, SEEK_SET) = 48404766720 read(4, "\7t\260\366\346\337\304\210\33\267j\35\377'\31f\372\252\ffU\317.y\211\360\36\240c\30`\34"..., 4096) = 4096 lseek(4, 41027002368, SEEK_SET) = 41027002368 write(4, "\232]7Ws\321\352\t\1@[+5\263\334\276{\343zZx\352\21\316`1\271[\202\350R`"..., 4096) = 4096 lseek(4, 48404770816, SEEK_SET) = 48404770816 read(4, "\17\362r\230\327\25\346//\210H\v\311\3237\323K\304\306\361a\223\311\324\272?\213\tq \370\24"..., 4096) = 4096 lseek(4, 41027006464, SEEK_SET) = 41027006464 write(4, "\367yy>x\216?=\324Z\305\351\376&\25\244\210\271\22\306}\276\237\370(\214\205G\262\360\257#"..., 4096) = 4096 lseek(4, 48404774912, SEEK_SET) = 48404774912 read(4, "\365\25\0\21|T\0\21}3t_\272\373\222k\r\177\303\1\201\261\221$\261B\232\3142\21U\316"..., 4096) = 4096 ^CProcess 3704 detached around 16 of these lines every second, so 4 read and 4 write operations every second, which I don't consider to be a lot.. And finally, my question: Will this process ever finish? If those numbers from fseek (48404774912) represent bytes, that would be something like 45 gigabytes, with this beeing a 3 terrabyte disk, which would give me 134 days to go, if the speed stays constant, and he scans the disk like this completly and only once. Do you have some advice for me? I have most of the data on that disk elsewhere, but I've put a lot of hours into sorting and merging it to this disk, so I would prefer to getting this disk up and running again, without formatting it anew. I don't think that the hardware is damaged since the disk is only a few months and since I can't see any I/O errors in the dmesg output. UPDATE: I just looked at the strace output again (2012-11-06_2300), now it looks like this: lseek(4, 1419860611072, SEEK_SET) = 1419860611072 read(4, "3#\f\2447\335\0\22A\355\374\276j\204'\207|\217V|\23\245[\7VP\251\242\276\207\317:"..., 4096) = 4096 lseek(4, 43018145792, SEEK_SET) = 43018145792 write(4, "]\206\231\342Y\204-2I\362\242\344\6R\205\361\324\177\265\317C\334V\324\260\334\275t=\10F."..., 4096) = 4096 lseek(4, 1419860615168, SEEK_SET) = 1419860615168 read(4, "\262\305\314Y\367\37x\326\245\226\226\320N\333$s\34\204\311\222\7\315\236\336\300TK\337\264\236\211n"..., 4096) = 4096 lseek(4, 43018149888, SEEK_SET) = 43018149888 write(4, "\271\224m\311\224\25!I\376\16;\377\0\223H\25Yd\201Y\342\r\203\271\24eG<\202{\373V"..., 4096) = 4096 lseek(4, 1419860619264, SEEK_SET) = 1419860619264 read(4, ";d\360\177\n\346\253\210\222|\250\352T\335M\33\260\320\261\7g\222P\344H?t\240\20\2548\310"..., 4096) = 4096 lseek(4, 43018153984, SEEK_SET) = 43018153984 write(4, "\360\252j\317\310\251G\227\335{\214`\341\267\31Y\202\360\v\374\307oq\3063\217Z\223\313\36D\211"..., 4096) = 4096 So this number of the lseeks before the reads, like 1419860619264 are already a lot bigger, standing for 1.29 terabytes if the numbers are bytes, so it doesn't seem to be a linear progress on a big scale, maybe there are only some areas that need work, that have big gaps in between them.

• Accessing a broken mdadm raid

  - by CarstenCarsten

  Hi! I used a western digital mybookworld (SOHO NAS storage using Linux) as backup for my Linux box. Suddenly, the mybookworld does not boot up any more. So I opened the box, removed the hard disk and put the hard disk into an external USB HDD case, and connected it to my Linux box. [ 530.640301] usb 2-1: new high speed USB device using ehci_hcd and address 3 [ 530.797630] scsi7 : usb-storage 2-1:1.0 [ 531.794844] scsi 7:0:0:0: Direct-Access WDC WD75 00AAKS-00RBA0 PQ: 0 ANSI: 2 [ 531.796490] sd 7:0:0:0: Attached scsi generic sg3 type 0 [ 531.797966] sd 7:0:0:0: [sdc] 1465149168 512-byte logical blocks: (750 GB/698 GiB) [ 531.800317] sd 7:0:0:0: [sdc] Write Protect is off [ 531.800327] sd 7:0:0:0: [sdc] Mode Sense: 38 00 00 00 [ 531.800333] sd 7:0:0:0: [sdc] Assuming drive cache: write through [ 531.803821] sd 7:0:0:0: [sdc] Assuming drive cache: write through [ 531.803836] sdc: sdc1 sdc2 sdc3 sdc4 [ 531.815831] sd 7:0:0:0: [sdc] Assuming drive cache: write through [ 531.815842] sd 7:0:0:0: [sdc] Attached SCSI disk The dmesg output looks normal, but I was wondering why the hardisk was not mounted at all. And why there are 4 different partitions on it. fdisk showed the following: root@ubuntu:/home/ubuntu# fdisk /dev/sdc WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u').

Everything seems to be created as a mdadm software raid. Calling mdadm --examine with the different partitions seems to affirm that. I think the only partition I am interested in, is /dev/sdc4 (because it is the largest). But nevertheless I called mdadm --examine with every partition. root@ubuntu:/home/ubuntu# mdadm --examine /dev/sdc1 /dev/sdc1: Magic : a92b4efc Version : 00.90.00 UUID : 5626a2d8:070ad992:ef1c8d24:cd8e13e4 Creation Time : Wed Feb 20 00:57:49 2002 Raid Level : raid1 Used Dev Size : 2939776 (2.80 GiB 3.01 GB) Array Size : 2939776 (2.80 GiB 3.01 GB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 1 Update Time : Sun Nov 21 11:05:27 2010 State : clean Active Devices : 1 Working Devices : 1 Failed Devices : 1 Spare Devices : 0 Checksum : 4c90bc55 - correct Events : 16682 Number Major Minor RaidDevice State this 0 8 1 0 active sync /dev/sda1 0 0 8 1 0 active sync /dev/sda1 1 1 0 0 1 faulty removed root@ubuntu:/home/ubuntu# mdadm --examine /dev/sdc2 /dev/sdc2: Magic : a92b4efc Version : 00.90.00 UUID : 9734b3ee:2d5af206:05fe3413:585f7f26 Creation Time : Wed Feb 20 00:57:54 2002 Raid Level : raid1 Used Dev Size : 104320 (101.89 MiB 106.82 MB) Array Size : 104320 (101.89 MiB 106.82 MB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 2 Update Time : Wed Oct 27 20:19:08 2010 State : clean Active Devices : 1 Working Devices : 1 Failed Devices : 1 Spare Devices : 0 Checksum : 55560b40 - correct Events : 9884 Number Major Minor RaidDevice State this 0 8 2 0 active sync /dev/sda2 0 0 8 2 0 active sync /dev/sda2 1 1 0 0 1 faulty removed root@ubuntu:/home/ubuntu# mdadm --examine /dev/sdc3 /dev/sdc3: Magic : a92b4efc Version : 00.90.00 UUID : 08f30b4f:91cca15d:2332bfef:48e67824 Creation Time : Wed Feb 20 00:57:54 2002 Raid Level : raid1 Used Dev Size : 987904 (964.91 MiB 1011.61 MB) Array Size : 987904 (964.91 MiB 1011.61 MB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 3 Update Time : Sun Nov 21 11:05:27 2010 State : clean Active Devices : 1 Working Devices : 1 Failed Devices : 1 Spare Devices : 0 Checksum : 39717874 - correct Events : 73678 Number Major Minor RaidDevice State this 0 8 3 0 active sync 0 0 8 3 0 active sync 1 1 0 0 1 faulty removed root@ubuntu:/home/ubuntu# mdadm --examine /dev/sdc4 /dev/sdc4: Magic : a92b4efc Version : 00.90.00 UUID : febb75ca:e9d1ce18:f14cc006:f759419a Creation Time : Wed Feb 20 00:57:55 2002 Raid Level : raid1 Used Dev Size : 728515520 (694.77 GiB 746.00 GB) Array Size : 728515520 (694.77 GiB 746.00 GB) Raid Devices : 2 Total Devices : 1 Preferred Minor : 4 Update Time : Sun Nov 21 11:05:27 2010 State : clean Active Devices : 1 Working Devices : 1 Failed Devices : 1 Spare Devices : 0 Checksum : 2f36a392 - correct Events : 519320 Number Major Minor RaidDevice State this 0 8 4 0 active sync 0 0 8 4 0 active sync 1 1 0 0 1 faulty removed If I read the output correctly everything was removed, because it was faulty. Is there ANY way to see the contents of the largest partition? Or seeing somehow which files are broken? I see that everything is raid1 which is only mirroring, so this should be a normal partition.

• More information wanted on error: CREATE ASSEMBLY for assembly failed because assembly failed verif

  - by turnip.cyberveggie

  I have a small application that uses SQL Server 2005 Express with CLR stored procedures. It has been successfully installed and runs on many computers running XP and Vista. To create the assembly the following SQL is executed (names changed to protect the innocent): CREATE ASSEMBLY myAssemblyName FROM 'c:\pathtoAssembly\myAssembly.dll' On one computer (a test machine that reflects other computers targeted for installation) that is running Vista and has some very aggressive security policy restrictions I receive the following error: << Start Error Message Msg 6218, Level 16, State 2, Server domain\servername, Line 2 CREATE ASSEMBLY for assembly 'myAssembly' failed because assembly 'myAssembly' failed verification. Check if the referenced assemblies are up-to-date and trusted (for external_access or unsafe) to execute in the database. CLR Verifier error messages if any will follow this message [ : myProcSupport.Axis::Proc1][mdToken=0x6000004] [HRESULT 0x8007000E] - Not enough storage is available to complete this operation.

The DLL is not normally signed, but I provided a signed version to test and received the same results. The installation is being done by someone else, and I don’t have access to the box, but they are executing scripts that I provided and work on other computers. I have tried to find information about this error beyond what the results of the script provide, but I haven’t found anything helpful. The person executing the script to create the assembly is logged in with an Admin account, is running CMD as admin, is connecting to the DB via Windows Authentication, has been added to the dbo_owner role, and added to the server role SysAdmin with the hopes that it is a permissions issue. This hasn't changed anything. Do I need to configure SQL Server 2005 Express differently for this environment? Is this error logged anywhere other than just the output from SQLCMD? What could cause this error? Could Vista security policies cause this? I don’t have access to the computer (the customer is doing the testing) so I can’t examine the box myself. TIA

• How to Reuse Your Old Wi-Fi Router as a Network Switch

  - by Jason Fitzpatrick

  Just because your old Wi-Fi router has been replaced by a newer model doesn’t mean it needs to gather dust in the closet. Read on as we show you how to take an old and underpowered Wi-Fi router and turn it into a respectable network switch (saving your $20 in the process). Image by mmgallan. Why Do I Want To Do This? Wi-Fi technology has changed significantly in the last ten years but Ethernet-based networking has changed very little. As such, a Wi-Fi router with 2006-era guts is lagging significantly behind current Wi-Fi router technology, but the Ethernet networking component of the device is just as useful as ever; aside from potentially being only 100Mbs instead of 1000Mbs capable (which for 99% of home applications is irrelevant) Ethernet is Ethernet. What does this matter to you, the consumer? It means that even though your old router doesn’t hack it for your Wi-Fi needs any longer the device is still a perfectly serviceable (and high quality) network switch. When do you need a network switch? Any time you want to share an Ethernet cable among multiple devices, you need a switch. For example, let’s say you have a single Ethernet wall jack behind your entertainment center. Unfortunately you have four devices that you want to link to your local network via hardline including your smart HDTV, DVR, Xbox, and a little Raspberry Pi running XBMC. Instead of spending $20-30 to purchase a brand new switch of comparable build quality to your old Wi-Fi router it makes financial sense (and is environmentally friendly) to invest five minutes of your time tweaking the settings on the old router to turn it from a Wi-Fi access point and routing tool into a network switch–perfect for dropping behind your entertainment center so that your DVR, Xbox, and media center computer can all share an Ethernet connection. What Do I Need? For this tutorial you’ll need a few things, all of which you likely have readily on hand or are free for download. To follow the basic portion of the tutorial, you’ll need the following: 1 Wi-Fi router with Ethernet ports 1 Computer with Ethernet jack 1 Ethernet cable For the advanced tutorial you’ll need all of those things, plus: 1 copy of DD-WRT firmware for your Wi-Fi router We’re conducting the experiment with a Linksys WRT54GL Wi-Fi router. The WRT54 series is one of the best selling Wi-Fi router series of all time and there’s a good chance a significant number of readers have one (or more) of them stuffed in an office closet. Even if you don’t have one of the WRT54 series routers, however, the principles we’re outlining here apply to all Wi-Fi routers; as long as your router administration panel allows the necessary changes you can follow right along with us. A quick note on the difference between the basic and advanced versions of this tutorial before we proceed. Your typical Wi-Fi router has 5 Ethernet ports on the back: 1 labeled “Internet”, “WAN”, or a variation thereof and intended to be connected to your DSL/Cable modem, and 4 labeled 1-4 intended to connect Ethernet devices like computers, printers, and game consoles directly to the Wi-Fi router. When you convert a Wi-Fi router to a switch, in most situations, you’ll lose two port as the “Internet” port cannot be used as a normal switch port and one of the switch ports becomes the input port for the Ethernet cable linking the switch to the main network. This means, referencing the diagram above, you’d lose the WAN port and LAN port 1, but retain LAN ports 2, 3, and 4 for use. If you only need to switch for 2-3 devices this may be satisfactory. However, for those of you that would prefer a more traditional switch setup where there is a dedicated WAN port and the rest of the ports are accessible, you’ll need to flash a third-party router firmware like the powerful DD-WRT onto your device. Doing so opens up the router to a greater degree of modification and allows you to assign the previously reserved WAN port to the switch, thus opening up LAN ports 1-4. Even if you don’t intend to use that extra port, DD-WRT offers you so many more options that it’s worth the extra few steps. Preparing Your Router for Life as a Switch Before we jump right in to shutting down the Wi-Fi functionality and repurposing your device as a network switch, there are a few important prep steps to attend to. First, you want to reset the router (if you just flashed a new firmware to your router, skip this step). Following the reset procedures for your particular router or go with what is known as the “Peacock Method” wherein you hold down the reset button for thirty seconds, unplug the router and wait (while still holding the reset button) for thirty seconds, and then plug it in while, again, continuing to hold down the rest button. Over the life of a router there are a variety of changes made, big and small, so it’s best to wipe them all back to the factory default before repurposing the router as a switch. Second, after resetting, we need to change the IP address of the device on the local network to an address which does not directly conflict with the new router. The typical default IP address for a home router is 192.168.1.1; if you ever need to get back into the administration panel of the router-turned-switch to check on things or make changes it will be a real hassle if the IP address of the device conflicts with the new home router. The simplest way to deal with this is to assign an address close to the actual router address but outside the range of addresses that your router will assign via the DHCP client; a good pick then is 192.168.1.2. Once the router is reset (or re-flashed) and has been assigned a new IP address, it’s time to configure it as a switch. Basic Router to Switch Configuration If you don’t want to (or need to) flash new firmware onto your device to open up that extra port, this is the section of the tutorial for you: we’ll cover how to take a stock router, our previously mentioned WRT54 series Linksys, and convert it to a switch. Hook the Wi-Fi router up to the network via one of the LAN ports (consider the WAN port as good as dead from this point forward, unless you start using the router in its traditional function again or later flash a more advanced firmware to the device, the port is officially retired at this point). Open the administration control panel via  web browser on a connected computer. Before we get started two things: first,  anything we don’t explicitly instruct you to change should be left in the default factory-reset setting as you find it, and two, change the settings in the order we list them as some settings can’t be changed after certain features are disabled. To start, let’s navigate to Setup ->Basic Setup. Here you need to change the following things: Local IP Address: [different than the primary router, e.g. 192.168.1.2] Subnet Mask: [same as the primary router, e.g. 255.255.255.0] DHCP Server: Disable Save with the “Save Settings” button and then navigate to Setup -> Advanced Routing: Operating Mode: Router This particular setting is very counterintuitive. The “Operating Mode” toggle tells the device whether or not it should enable the Network Address Translation (NAT)  feature. Because we’re turning a smart piece of networking hardware into a relatively dumb one, we don’t need this feature so we switch from Gateway mode (NAT on) to Router mode (NAT off). Our next stop is Wireless -> Basic Wireless Settings: Wireless SSID Broadcast: Disable Wireless Network Mode: Disabled After disabling the wireless we’re going to, again, do something counterintuitive. Navigate to Wireless -> Wireless Security and set the following parameters: Security Mode: WPA2 Personal WPA Algorithms: TKIP+AES WPA Shared Key: [select some random string of letters, numbers, and symbols like JF#d$di!Hdgio890] Now you may be asking yourself, why on Earth are we setting a rather secure Wi-Fi configuration on a Wi-Fi router we’re not going to use as a Wi-Fi node? On the off chance that something strange happens after, say, a power outage when your router-turned-switch cycles on and off a bunch of times and the Wi-Fi functionality is activated we don’t want to be running the Wi-Fi node wide open and granting unfettered access to your network. While the chances of this are next-to-nonexistent, it takes only a few seconds to apply the security measure so there’s little reason not to. Save your changes and navigate to Security ->Firewall. Uncheck everything but Filter Multicast Firewall Protect: Disable At this point you can save your changes again, review the changes you’ve made to ensure they all stuck, and then deploy your “new” switch wherever it is needed. Advanced Router to Switch Configuration For the advanced configuration, you’ll need a copy of DD-WRT installed on your router. Although doing so is an extra few steps, it gives you a lot more control over the process and liberates an extra port on the device. Hook the Wi-Fi router up to the network via one of the LAN ports (later you can switch the cable to the WAN port). Open the administration control panel via web browser on the connected computer. Navigate to the Setup -> Basic Setup tab to get started. In the Basic Setup tab, ensure the following settings are adjusted. The setting changes are not optional and are required to turn the Wi-Fi router into a switch. WAN Connection Type: Disabled Local IP Address: [different than the primary router, e.g. 192.168.1.2] Subnet Mask: [same as the primary router, e.g. 255.255.255.0] DHCP Server: Disable In addition to disabling the DHCP server, also uncheck all the DNSMasq boxes as the bottom of the DHCP sub-menu. If you want to activate the extra port (and why wouldn’t you), in the WAN port section: Assign WAN Port to Switch [X] At this point the router has become a switch and you have access to the WAN port so the LAN ports are all free. Since we’re already in the control panel, however, we might as well flip a few optional toggles that further lock down the switch and prevent something odd from happening. The optional settings are arranged via the menu you find them in. Remember to save your settings with the save button before moving onto a new tab. While still in the Setup -> Basic Setup menu, change the following: Gateway/Local DNS : [IP address of primary router, e.g. 192.168.1.1] NTP Client : Disable The next step is to turn off the radio completely (which not only kills the Wi-Fi but actually powers the physical radio chip off). Navigate to Wireless -> Advanced Settings -> Radio Time Restrictions: Radio Scheduling: Enable Select “Always Off” There’s no need to create a potential security problem by leaving the Wi-Fi radio on, the above toggle turns it completely off. Under Services -> Services: DNSMasq : Disable ttraff Daemon : Disable Under the Security -> Firewall tab, uncheck every box except “Filter Multicast”, as seen in the screenshot above, and then disable SPI Firewall. Once you’re done here save and move on to the Administration tab. Under Administration -> Management:  Info Site Password Protection : Enable Info Site MAC Masking : Disable CRON : Disable 802.1x : Disable Routing : Disable After this final round of tweaks, save and then apply your settings. Your router has now been, strategically, dumbed down enough to plod along as a very dependable little switch. Time to stuff it behind your desk or entertainment center and streamline your cabling.

• Apache2 VirtualHost Configuration with SSL

  - by Peter

  Hello! I'm new here and I have a strange problem which needs to be solved. Previously I searched in the whole forum and I've read all of related questions but I didn't find solution to my question. We have two servers and a firewall computer. On the Server#1 there is an Apache 2.2 web server and it forwards the incoming traffic to the appropriate ports, to our subdomains by its virtual host configuration (Apache, Tomcat, IIS, Server#2 and so on). We recently bought an SSL certificate to protect one of our subdomain. I successfully installed and configured the certificate into the Apache and it works flawlessly within our local network. Our Kerio Winroute Firewall is configured to permit https traffic and it is translated to Server#1. But all of our subdomains are unavailable from outside (http & https too). Web browser shows "Failed to connect" message. Now, I enclose some parts from our httpd.conf and httpd-vhosts.conf file. httpd.conf ServerRoot "C:/Program Files/Apache Software Foundation/Apache2.2" Listen 80 ServerName dev.mydomain.hu:80 DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" LoadModule proxy_module modules/mod_proxy.so LoadModule proxy_connect_module modules/mod_proxy_connect.so LoadModule proxy_http_module modules/mod_proxy_http.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule ssl_module modules/mod_ssl.so Include conf/extra/httpd-vhosts.conf <IfModule ssl_module> SSLMutex default SSLRandomSeed startup builtin SSLRandomSeed connect builtin SSLSessionCache none </IfModule> httpd-vhosts.conf NameVirtualHost *:80 NameVirtualHost *:443 Listen 443 <VirtualHost *:80> DocumentRoot "C:/Program Files/Apache Software Foundation/Apache2.2/htdocs" ServerName localhost </VirtualHost> #-------EXCHANGE SERVER-------- <VirtualHost *:80> ServerName intra.mydomain.hu ProxyRequests Off ProxyVia On ProxyPass / http://myserver:8080/ ProxyPassReverse / http://myserver:8080/ <Proxy *:80> Order deny,allow Allow from all </Proxy> <Location /> Order allow,deny Allow from all </Location> ErrorLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/exchange.log" CustomLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/exchange_cust.log" common LogLevel info </VirtualHost> #--------FITNESSE SERVER------- <VirtualHost *:80> ServerName test.mydomain.hu ProxyRequests Off <Proxy *:80> Order deny,allow Allow from all </Proxy> ProxyPass / http://myserver:8004/ ProxyPassReverse / http://myserver:8004/ <Location /> AuthType Basic AuthName "FitNesse" AuthUserFile "C:/Program Files/Apache Software Foundation/Apache2.2/auth/password" AuthGroupFile "C:/Program Files/Apache Software Foundation/Apache2.2/auth/pwgroup" require group Users Order allow,deny Allow from all </Location> ErrorLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/fitnesse.log" CustomLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/fitnesse_cust.log" common LogLevel info </VirtualHost> #----WIKI SERVER-----(SSL)- <VirtualHost *:80 *:443> ServerName wiki.mydomain.hu ServerAlias wiki.mydomain.hu SSLEngine On SSLCertificateFile "C:/Program Files/Apache Software Foundation/Apache2.2/cert/certificate.cer" SSLCertificateKeyFile "C:/Program Files/Apache Software Foundation/Apache2.2/cert/wiki.itkodex.hu.key" ProxyRequests Off <Proxy *:80> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8000/ ProxyPassReverse / http://localhost:8000/ ErrorLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/wiki.log" CustomLog "c:/Program Files/Apache Software Foundation/Apache2.2/logs/wikicust.log" common LogLevel info </VirtualHost> Because this wiki is a JSPWIKI web application, runs on Apache Tomcat therefore there is no "DocumentRoot" parameter in the VirtualHost.

• [GEEK SCHOOL] Network Security 1: Securing User Accounts and Passwords in Windows

  - by Matt Klein

  This How-To Geek School class is intended for people who want to learn more about security when using Windows operating systems. You will learn many principles that will help you have a more secure computing experience and will get the chance to use all the important security tools and features that are bundled with Windows. Obviously, we will share everything you need to know about using them effectively. In this first lesson, we will talk about password security; the different ways of logging into Windows and how secure they are. In the proceeding lesson, we will explain where Windows stores all the user names and passwords you enter while working in this operating systems, how safe they are, and how to manage this data. Moving on in the series, we will talk about User Account Control, its role in improving the security of your system, and how to use Windows Defender in order to protect your system from malware. Then, we will talk about the Windows Firewall, how to use it in order to manage the apps that get access to the network and the Internet, and how to create your own filtering rules. After that, we will discuss the SmartScreen Filter – a security feature that gets more and more attention from Microsoft and is now widely used in its Windows 8.x operating systems. Moving on, we will discuss ways to keep your software and apps up-to-date, why this is important and which tools you can use to automate this process as much as possible. Last but not least, we will discuss the Action Center and its role in keeping you informed about what’s going on with your system and share several tips and tricks about how to stay safe when using your computer and the Internet. Let’s get started by discussing everyone’s favorite subject: passwords. The Types of Passwords Found in Windows In Windows 7, you have only local user accounts, which may or may not have a password. For example, you can easily set a blank password for any user account, even if that one is an administrator. The only exception to this rule are business networks where domain policies force all user accounts to use a non-blank password. In Windows 8.x, you have both local accounts and Microsoft accounts. If you would like to learn more about them, don’t hesitate to read the lesson on User Accounts, Groups, Permissions & Their Role in Sharing, in our Windows Networking series. Microsoft accounts are obliged to use a non-blank password due to the fact that a Microsoft account gives you access to Microsoft services. Using a blank password would mean exposing yourself to lots of problems. Local accounts in Windows 8.1 however, can use a blank password. On top of traditional passwords, any user account can create and use a 4-digit PIN or a picture password. These concepts were introduced by Microsoft to speed up the sign in process for the Windows 8.x operating system. However, they do not replace the use of a traditional password and can be used only in conjunction with a traditional user account password. Another type of password that you encounter in Windows operating systems is the Homegroup password. In a typical home network, users can use the Homegroup to easily share resources. A Homegroup can be joined by a Windows device only by using the Homegroup password. If you would like to learn more about the Homegroup and how to use it for network sharing, don’t hesitate to read our Windows Networking series. What to Keep in Mind When Creating Passwords, PINs and Picture Passwords When creating passwords, a PIN, or a picture password for your user account, we would like you keep in mind the following recommendations: Do not use blank passwords, even on the desktop computers in your home. You never know who may gain unwanted access to them. Also, malware can run more easily as administrator because you do not have a password. Trading your security for convenience when logging in is never a good idea. When creating a password, make it at least eight characters long. Make sure that it includes a random mix of upper and lowercase letters, numbers, and symbols. Ideally, it should not be related in any way to your name, username, or company name. Make sure that your passwords do not include complete words from any dictionary. Dictionaries are the first thing crackers use to hack passwords. Do not use the same password for more than one account. All of your passwords should be unique and you should use a system like LastPass, KeePass, Roboform or something similar to keep track of them. When creating a PIN use four different digits to make things slightly harder to crack. When creating a picture password, pick a photo that has at least 10 “points of interests”. Points of interests are areas that serve as a landmark for your gestures. Use a random mixture of gesture types and sequence and make sure that you do not repeat the same gesture twice. Be aware that smudges on the screen could potentially reveal your gestures to others. The Security of Your Password vs. the PIN and the Picture Password Any kind of password can be cracked with enough effort and the appropriate tools. There is no such thing as a completely secure password. However, passwords created using only a few security principles are much harder to crack than others. If you respect the recommendations shared in the previous section of this lesson, you will end up having reasonably secure passwords. Out of all the log in methods in Windows 8.x, the PIN is the easiest to brute force because PINs are restricted to four digits and there are only 10,000 possible unique combinations available. The picture password is more secure than the PIN because it provides many more opportunities for creating unique combinations of gestures. Microsoft have compared the two login options from a security perspective in this post: Signing in with a picture password. In order to discourage brute force attacks against picture passwords and PINs, Windows defaults to your traditional text password after five failed attempts. The PIN and the picture password function only as alternative login methods to Windows 8.x. Therefore, if someone cracks them, he or she doesn’t have access to your user account password. However, that person can use all the apps installed on your Windows 8.x device, access your files, data, and so on. How to Create a PIN in Windows 8.x If you log in to a Windows 8.x device with a user account that has a non-blank password, then you can create a 4-digit PIN for it, to use it as a complementary login method. In order to create one, you need to go to “PC Settings”. If you don’t know how, then press Windows + C on your keyboard or flick from the right edge of the screen, on a touch-enabled device, then press “Settings”. The Settings charm is now open. Click or tap the link that says “Change PC settings”, on the bottom of the charm. In PC settings, go to Accounts and then to “Sign-in options”. Here you will find all the necessary options for changing your existing password, creating a PIN, or a picture password. To create a PIN, press the “Add” button in the PIN section. The “Create a PIN” wizard is started and you are asked to enter the password of your user account. Type it and press “OK”. Now you are asked to enter a 4-digit pin in the “Enter PIN” and “Confirm PIN” fields. The PIN has been created and you can now use it to log in to Windows. How to Create a Picture Password in Windows 8.x If you log in to a Windows 8.x device with a user account that has a non-blank password, then you can also create a picture password and use it as a complementary login method. In order to create one, you need to go to “PC settings”. In PC Settings, go to Accounts and then to “Sign-in options”. Here you will find all the necessary options for changing your existing password, creating a PIN, or a picture password. To create a picture password, press the “Add” button in the “Picture password” section. The “Create a picture password” wizard is started and you are asked to enter the password of your user account. You are shown a guide on how the picture password works. Take a few seconds to watch it and learn the gestures that can be used for your picture password. You will learn that you can create a combination of circles, straight lines, and taps. When ready, press “Choose picture”. Browse your Windows 8.x device and select the picture you want to use for your password and press “Open”. Now you can drag the picture to position it the way you want. When you like how the picture is positioned, press “Use this picture” on the left. If you are not happy with the picture, press “Choose new picture” and select a new one, as shown during the previous step. After you have confirmed that you want to use this picture, you are asked to set up your gestures for the picture password. Draw three gestures on the picture, any combination you wish. Please remember that you can use only three gestures: circles, straight lines, and taps. Once you have drawn those three gestures, you are asked to confirm. Draw the same gestures one more time. If everything goes well, you are informed that you have created your picture password and that you can use it the next time you sign in to Windows. If you don’t confirm the gestures correctly, you will be asked to try again, until you draw the same gestures twice. To close the picture password wizard, press “Finish”. Where Does Windows Store Your Passwords? Are They Safe? All the passwords that you enter in Windows and save for future use are stored in the Credential Manager. This tool is a vault with the usernames and passwords that you use to log on to your computer, to other computers on the network, to apps from the Windows Store, or to websites using Internet Explorer. By storing these credentials, Windows can automatically log you the next time you access the same app, network share, or website. Everything that is stored in the Credential Manager is encrypted for your protection.

• Announcing ASP.NET MVC 3 (Release Candidate 2)

  - by ScottGu

  Earlier today the ASP.NET team shipped the final release candidate (RC2) for ASP.NET MVC 3.  You can download and install it here. Almost there… Today’s RC2 release is the near-final release of ASP.NET MVC 3, and is a true “release candidate” in that we are hoping to not make any more code changes with it.  We are publishing it today so that people can do final testing with it, let us know if they find any last minute “showstoppers”, and start updating their apps to use it.  We will officially ship the final ASP.NET MVC 3 “RTM” build in January. Works with both VS 2010 and VS 2010 SP1 Beta Today’s ASP.NET MVC 3 RC2 release works with both the shipping version of Visual Studio 2010 / Visual Web Developer 2010 Express, as well as the newly released VS 2010 SP1 Beta.  This means that you do not need to install VS 2010 SP1 (or the SP1 beta) in order to use ASP.NET MVC 3.  It works just fine with the shipping Visual Studio 2010.  I’ll do a blog post next week, though, about some of the nice additional feature goodies that come with VS 2010 SP1 (including IIS Express and SQL CE support within VS) which make the dev experience for both ASP.NET Web Forms and ASP.NET MVC even better. Bugs and Perf Fixes Today’s ASP.NET MVC 3 RC2 build contains many bug fixes and performance optimizations.  Our latest performance tests indicate that ASP.NET MVC 3 is now faster than ASP.NET MVC 2, and that existing ASP.NET MVC applications will experience a slight performance increase when updated to run using ASP.NET MVC 3. Final Tweaks and Fit-N-Finish In addition to bug fixes and performance optimizations, today’s RC2 build contains a number of last-minute feature tweaks and “fit-n-finish” changes for the new ASP.NET MVC 3 features.  The feedback and suggestions we’ve received during the public previews has been invaluable in guiding these final tweaks, and we really appreciate people’s support in sending this feedback our way.  Below is a short-list of some of the feature changes/tweaks made between last month’s ASP.NET MVC 3 RC release and today’s ASP.NET MVC 3 RC2 release: jQuery updates and addition of jQuery UI The default ASP.NET MVC 3 project templates have been updated to include jQuery 1.4.4 and jQuery Validation 1.7.  We are also excited to announce today that we are including jQuery UI within our default ASP.NET project templates going forward.  jQuery UI provides a powerful set of additional UI widgets and capabilities.  It will be added by default to your project’s \scripts folder when you create new ASP.NET MVC 3 projects. Improved View Scaffolding The T4 templates used for scaffolding views with the Add-View dialog now generates views that use Html.EditorFor instead of helpers such as Html.TextBoxFor. This change enables you to optionally annotate models with metadata (using data annotation attributes) to better customize the output of your UI at runtime. The Add View scaffolding also supports improved detection and usage of primary key information on models (including support for naming conventions like ID, ProductID, etc).  For example: the Add View dialog box uses this information to ensure that the primary key value is not scaffold as an editable form field, and that links between views are auto-generated correctly with primary key information. The default Edit and Create templates also now include references to the jQuery scripts needed for client validation.  Scaffold form views now support client-side validation by default (no extra steps required).  Client-side validation with ASP.NET MVC 3 is also done using an unobtrusive javascript approach – making pages fast and clean. [ControllerSessionState] –> [SessionState] ASP.NET MVC 3 adds support for session-less controllers.  With the initial RC you used a [ControllerSessionState] attribute to specify this.  We shortened this in RC2 to just be [SessionState]: Note that in addition to turning off session state, you can also set it to be read-only (which is useful for webfarm scenarios where you are reading but not updating session state on a particular request). [SkipRequestValidation] –> [AllowHtml] ASP.NET MVC includes built-in support to protect against HTML and Cross-Site Script Injection Attacks, and will throw an error by default if someone tries to post HTML content as input.  Developers need to explicitly indicate that this is allowed (and that they’ve hopefully built their app to securely support it) in order to enable it. With ASP.NET MVC 3, we are also now supporting a new attribute that you can apply to properties of models/viewmodels to indicate that HTML input is enabled, which enables much more granular protection in a DRY way.  In last month’s RC release this attribute was named [SkipRequestValidation].  With RC2 we renamed it to [AllowHtml] to make it more intuitive: Setting the above [AllowHtml] attribute on a model/viewmodel will cause ASP.NET MVC 3 to turn off HTML injection protection when model binding just that property. Html.Raw() helper method The new Razor view engine introduced with ASP.NET MVC 3 automatically HTML encodes output by default.  This helps provide an additional level of protection against HTML and Script injection attacks. With RC2 we are adding a Html.Raw() helper method that you can use to explicitly indicate that you do not want to HTML encode your output, and instead want to render the content “as-is”: ViewModel/View –> ViewBag ASP.NET MVC has (since V1) supported a ViewData[] dictionary within Controllers and Views that enables developers to pass information from a Controller to a View in a late-bound way.  This approach can be used instead of, or in combination with, a strongly-typed model class.  The below code demonstrates a common use case – where a strongly typed Product model is passed to the view in addition to two late-bound variables via the ViewData[] dictionary: With ASP.NET MVC 3 we are introducing a new API that takes advantage of the dynamic type support within .NET 4 to set/retrieve these values.  It allows you to use standard “dot” notation to specify any number of additional variables to be passed, and does not require that you create a strongly-typed class to do so.  With earlier previews of ASP.NET MVC 3 we exposed this API using a dynamic property called “ViewModel” on the Controller base class, and with a dynamic property called “View” within view templates.  A lot of people found the fact that there were two different names confusing, and several also said that using the name ViewModel was confusing in this context – since often you create strongly-typed ViewModel classes in ASP.NET MVC, and they do not use this API.  With RC2 we are exposing a dynamic property that has the same name – ViewBag – within both Controllers and Views.  It is a dynamic collection that allows you to pass additional bits of data from your controller to your view template to help generate a response.  Below is an example of how we could use it to pass a time-stamp message as well as a list of all categories to our view template: Below is an example of how our view template (which is strongly-typed to expect a Product class as its model) can use the two extra bits of information we passed in our ViewBag to generate the response.  In particular, notice how we are using the list of categories passed in the dynamic ViewBag collection to generate a dropdownlist of friendly category names to help set the CategoryID property of our Product object.  The above Controller/View combination will then generate an HTML response like below.    Output Caching Improvements ASP.NET MVC 3’s output caching system no longer requires you to specify a VaryByParam property when declaring an [OutputCache] attribute on a Controller action method.  MVC3 now automatically varies the output cached entries when you have explicit parameters on your action method – allowing you to cleanly enable output caching on actions using code like below: In addition to supporting full page output caching, ASP.NET MVC 3 also supports partial-page caching – which allows you to cache a region of output and re-use it across multiple requests or controllers.  The [OutputCache] behavior for partial-page caching was updated with RC2 so that sub-content cached entries are varied based on input parameters as opposed to the URL structure of the top-level request – which makes caching scenarios both easier and more powerful than the behavior in the previous RC. @model declaration does not add whitespace In earlier previews, the strongly-typed @model declaration at the top of a Razor view added a blank line to the rendered HTML output. This has been fixed so that the declaration does not introduce whitespace. Changed "Html.ValidationMessage" Method to Display the First Useful Error Message The behavior of the Html.ValidationMessage() helper was updated to show the first useful error message instead of simply displaying the first error. During model binding, the ModelState dictionary can be populated from multiple sources with error messages about the property, including from the model itself (if it implements IValidatableObject), from validation attributes applied to the property, and from exceptions thrown while the property is being accessed. When the Html.ValidationMessage() method displays a validation message, it now skips model-state entries that include an exception, because these are generally not intended for the end user. Instead, the method looks for the first validation message that is not associated with an exception and displays that message. If no such message is found, it defaults to a generic error message that is associated with the first exception. RemoteAttribute “Fields” -> “AdditionalFields” ASP.NET MVC 3 includes built-in remote validation support with its validation infrastructure.  This means that the client-side validation script library used by ASP.NET MVC 3 can automatically call back to controllers you expose on the server to determine whether an input element is indeed valid as the user is editing the form (allowing you to provide real-time validation updates). You can accomplish this by decorating a model/viewmodel property with a [Remote] attribute that specifies the controller/action that should be invoked to remotely validate it.  With the RC this attribute had a “Fields” property that could be used to specify additional input elements that should be sent from the client to the server to help with the validation logic.  To improve the clarity of what this property does we have renamed it to “AdditionalFields” with today’s RC2 release. ViewResult.Model and ViewResult.ViewBag Properties The ViewResult class now exposes both a “Model” and “ViewBag” property off of it.  This makes it easier to unit test Controllers that return views, and avoids you having to access the Model via the ViewResult.ViewData.Model property. Installation Notes You can download and install the ASP.NET MVC 3 RC2 build here.  It can be installed on top of the previous ASP.NET MVC 3 RC release (it should just replace the bits as part of its setup). The one component that will not be updated by the above setup (if you already have it installed) is the NuGet Package Manager.  If you already have NuGet installed, please go to the Visual Studio Extensions Manager (via the Tools –> Extensions menu option) and click on the “Updates” tab.  You should see NuGet listed there – please click the “Update” button next to it to have VS update the extension to today’s release. If you do not have NuGet installed (and did not install the ASP.NET MVC RC build), then NuGet will be installed as part of your ASP.NET MVC 3 setup, and you do not need to take any additional steps to make it work. Summary We are really close to the final ASP.NET MVC 3 release, and will deliver the final “RTM” build of it next month.  It has been only a little over 7 months since ASP.NET MVC 2 shipped, and I’m pretty amazed by the huge number of new features, improvements, and refinements that the team has been able to add with this release (Razor, Unobtrusive JavaScript, NuGet, Dependency Injection, Output Caching, and a lot, lot more).  I’ll be doing a number of blog posts over the next few weeks talking about many of them in more depth. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• Not All “Viruses” Are Viruses: 10 Malware Terms Explained

  - by Chris Hoffman

  Most people seem to call every type of malware a “virus”, but that isn’t technically accurate. You’ve probably heard of many more terms beyond virus: malware, worm, Trojan, rootkit, keylogger, spyware, and more. But what do all these terms mean? These terms aren’t just used by geeks. They make their way into even mainstream news stories about the latest web security problems and tech scares. Understanding them will help you understand the dangers your\ hear about. Malware The word “malware” is short for “malicious software.” Many people use the word “virus” to indicate any type of harmful software, but a virus is actually just a specific type of malware. The word “malware” encompasses all harmful software, including all the ones listed below. Virus Let’s start with viruses. A virus is a type of malware that copies itself by infecting other files,  just as viruses in the real world infect biological cells and use those biological cells to reproduce copies of themselves. A virus can do many different things — watch in the background and steal your passwords, display advertisements, or just crash your computer — but the key thing that makes it a virus is how it spreads. When you run a virus, it will infect programs on your computer. When you run the program on another computer, the virus will infect programs on that computer, and so on. For example, a virus might infect program files on a USB stick. When the programs on that USB stick are run on another computer, the virus runs on the other computer and infects more program files. The virus will continue to spread in this way. Worm A worm is similar to a virus, but it spreads a different way. Rather than infecting files and relying on human activity to move those files around and run them on different systems, a worm spreads over computer networks on its own accord. For example, the Blaster and Sasser worms spread very quickly in the days of Windows XP because Windows XP did not come properly secured and exposed system services to the Internet. The worm accessed these system services over the Internet, exploited a vulnerability, and infected the computer. The worm then used the new infected computer to continue replicating itself. Such worms are less common now that Windows is properly firewalled by default, but worms can also spread in other ways — for example, by mass-emailing themselves to every email address in an effected user’s address book. Like a virus, a worm can do any number of other harmful things once it infects a computer. The key thing that makes it a worm is simply how it spreads copies of itself. Trojan (or Trojan Horse) A Trojan horse, or Trojan, is a type of malware that disguises itself as a legitimate file. When you download and run the program, the Trojan horse will run in the background, allowing third-parties to access your computer. Trojans can do this for any number of reasons — to monitor activity on your computer, to join your computer to a botnet. Trojans may also be used to open the floodgates and download many other types of malware onto your computer. The key thing that makes this type of malware a Trojan is how it arrives. It pretends to be a useful program and, when run, it hides in the background and gives malicious people access to your computer. It isn’t obsessed with copying itself into other files or spreading over the network, as viruses and worms are. For example, a piece of pirated software on an unscrupulous website may actually contain a Trojan. Spyware Spyware is a type of malicious software that spies on you without your knowledge. It collects a variety of different types of data, depending on the piece of spyware. Different types of malware can function as spyware — there may be malicious spyware included in Trojans that spies on your keystrokes to steal financial data, for example. More “legitimate” spyware may be bundled along with free software and simply monitor your web browsing habits, uploading this data to advertising servers so the software’s creator can make money from selling their knowledge of your activities. Adware Adware often comes along with spyware. It’s any type of software that displays advertising on your computer. Programs that display advertisements inside the program itself aren’t generally classified as malware. The kind of “adware” that’s particularly malicious is the kind that abuses its access to your system to display ads when it shouldn’t. For example, a piece of harmful adware may cause pop-up advertisements to appear on your computer when you’re not doing anything else. Or, adware may inject additional advertising into other web pages as you browse the web. Adware is often combined with spyware — a piece of malware may monitor your browsing habits and use them to serve you more targeted ads. Adware is more “socially acceptable” than other types of malware on Windows and you may see adware bundled with legitimate programs. For example, some people consider the Ask Toolbar included with Oracle’s Java software adware. Keylogger A keylogger is a type of malware that runs in the background, recording every key stroke you make. These keystrokes can include usernames, passwords, credit card numbers, and other sensitive data. The keylogger then, most likely, uploads these keystrokes to a malicious server, where it can be analyzed and people can pick out the useful passwords and credit card numbers. Other types of malware can act as keyloggers. A virus, worm, or Trojan may function as a keylogger, for example. Keyloggers may also be installed for monitoring purposes by businesses or even jealous spouses. Botnet, Bot A botnet is a large network of computers that are under the botnet creator’s control. Each computer functions as a “bot” because it’s infected with a specific piece of malware. Once the bot software infects the computer, ir will connect to some sort of control server and wait for instructions from the botnet’s creator. For example, a botnet may be used to initiate a DDoS (distributed denial of service) attack. Every computer in the botnet will be told to bombard a specific website or server with requests at once, and such millions or requests can cause a server to become unresponsive or crash. Botnet creators may sell access to their botnets, allowing other malicious individuals to use large botnets to do their dirty work. Rootkit A rootkit is a type of malware designed to burrow deep into your computer, avoiding detection by security programs and users. For example, a rootkit might load before most of Windows, burying itself deep into the system and modifying system functions so that security programs can’t detect it. A rootkit might hide itself completely, preventing itself from showing up in the Windows task manager. The key thing that makes a type of malware a rootkit is that it’s stealthy and focused on hiding itself once it arrives. Ransomware Ransomware is a fairly new type of malware. It holds your computer or files hostage and demands a ransom payment. Some ransomware may simply pop up a box asking for money before you can continue using your computer. Such prompts are easily defeated with antivirus software. More harmful malware like CryptoLocker literally encrypts your files and demands a payment before you can access them. Such types of malware are dangerous, especially if you don’t have backups. Most malware these days is produced for profit, and ransomware is a good example of that. Ransomware doesn’t want to crash your computer and delete your files just to cause you trouble. It wants to take something hostage and get a quick payment from you. So why is it called “antivirus software,” anyway? Well, most people continue to consider the word “virus” synonymous with malware as a whole. Antivirus software doesn’t just protect against viruses, but against all types of malware. It may be more accurately referred to as “antimalware” or “security” software.

• JPA thinks I'm deleting a detached object

  - by Steve

  So, I've got a DAO that I used to load and save my domain objects using JPA. I finally managed to get the transaction stuff working (with a bunch of help from the folks here...), now I've got another issue. In my test case, I call my DAO to load a domain object with a given id, check that it got loaded and then call the same DAO to delete the object I just loaded. When I do that I get the following: java.lang.IllegalArgumentException: Removing a detached instance mil.navy.ndms.conops.common.model.impl.jpa.Group#10 at org.hibernate.ejb.event.EJB3DeleteEventListener.performDetachedEntityDeletionCheck(EJB3DeleteEventListener.java:45) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:108) at org.hibernate.event.def.DefaultDeleteEventListener.onDelete(DefaultDeleteEventListener.java:74) at org.hibernate.impl.SessionImpl.fireDelete(SessionImpl.java:794) at org.hibernate.impl.SessionImpl.delete(SessionImpl.java:772) at org.hibernate.ejb.AbstractEntityManagerImpl.remove(AbstractEntityManagerImpl.java:253) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at org.springframework.orm.jpa.SharedEntityManagerCreator$SharedEntityManagerInvocationHandler.invoke(SharedEntityManagerCreator.java:180) at $Proxy27.remove(Unknown Source) at mil.navy.ndms.conops.common.dao.impl.jpa.GroupDao.delete(GroupDao.java:499) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at org.springframework.aop.support.AopUtils.invokeJoinpointUsingReflection(AopUtils.java:304) at org.springframework.aop.framework.ReflectiveMethodInvocation.invokeJoinpoint(ReflectiveMethodInvocation.java:182) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:149) at org.springframework.transaction.interceptor.TransactionInterceptor.invoke(TransactionInterceptor.java:106) at org.springframework.aop.framework.ReflectiveMethodInvocation.proceed(ReflectiveMethodInvocation.java:171) at org.springframework.aop.framework.JdkDynamicAopProxy.invoke(JdkDynamicAopProxy.java:204) at $Proxy28.delete(Unknown Source) at mil.navy.ndms.conops.common.dao.impl.jpa.GroupDaoTest.testGroupDaoSave(GroupDaoTest.java:89) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:48) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:600) at junit.framework.TestCase.runTest(TestCase.java:164) at junit.framework.TestCase.runBare(TestCase.java:130) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:196) Now given that I'm using the same DAO instance, and I've not changed EntityManagers (unless Spring does so without letting me know), how can this be a detached object? My DAO code looks like this: public class GenericJPADao implements IWebDao, IDao, IDaoUtil { private static Logger logger = Logger.getLogger (GenericJPADao.class); protected Class voClass; @PersistenceContext(unitName = "CONOPS_PU") protected EntityManagerFactory emf; @PersistenceContext(unitName = "CONOPS_PU") protected EntityManager em; public GenericJPADao() { super ( ); ParameterizedType genericSuperclass = (ParameterizedType) getClass ( ).getGenericSuperclass ( ); this.voClass = (Class) genericSuperclass.getActualTypeArguments ( )[1]; } ... public void delete (INTFC modelObj, EntityManager em) { em.remove (modelObj); } @SuppressWarnings("unchecked") public INTFC findById (Long id) { return ((INTFC) em.find (voClass, id)); } } The test case code looks like: IGroup loadedGroup = dao.findById (group.getId ( )); assertNotNull (loadedGroup); assertEquals (group.getId ( ), loadedGroup.getId ( )); dao.delete (loadedGroup); // - This generates the above exception loadedGroup = dao.findById (group.getId ( )); assertNull(loadedGroup); Can anyone tell me what I'm doing wrong here? Thanks
