• Two network cards in one Windows 7 PC

  - by Martin

  Hi, I've upgraded from Vista to Windows 7. On Vista I used to run one network card (Intel 82566DC -2 Gigabit) for my internet which was connected to a Dovado USB mobile broadband router connected to a 3G modem. The IP setup on the card is set on DHCP. The second card (3com Ethernet link) was used to connect to our town's local WUG (wireless user group) and all worked fine. Now the problem I have with Windows 7 is that when I connect to the internet with the (Intel) first card, the internet work fine but as soon as I connect the second card to the wug my internet drops. If I then disconnect the first card (internet one) and try to connect to the wug it works. It seems that the two cards are fighting each other. Is there maybe something I can do to fix the problem? As you probably can gather from this post is that I am not an expert on PC's so please if you do answer do I in simple terms. :) Thanks, Martin

• configure pppoe on wrt54gl(openwrt)

  - by sunny

  Hi, I have home DSL connection from my ISP with a beetel modem at my end. I want to make my network wireless, so i bought a linksys wrt54gl and installed open-wrt on it. My ISP provides dynamic IP's with me connecting via pppoe. My question is how do I configure openwrt to work with this. Please suggest what option should I go with, or any other you recommend. DSL cable--Beetel Modem-- Wrt54gl in bridge mode with beetel modem doing the pppoe and having a DHCP server. DSL cable--Wrt54gl with wrt54gl handling the pppoe. Is option 2 possible, can I have a setup without bringing the beetel modem in the picture at all?

• Can't log in using sa account for sql server 2008

  - by tessa

  I installed SQL Server 2008. During the install I set it to mixed mode authentication and set the password for what I assume is the sa account. In the configuration manager I set tcp/ip and named pipes to enabled. When I open SQL Server Management Studio and try to log in - username: sa, password: whatIjustsetintheinstall, it fails with the error: Login failed for user sa. (error 18456). The error in Event Viewer is - Login failed for user 'sa'. Reason: Password did not match that for the login provided. [CLIENT: <local machine>]. I know the password is right because I just set it. What am I doing wrong here? Is sa not the right user to be logging in with mixed mode? I've been reading through forum after forum but just cannot find anything that works.

• mdadm email notification - change the default subject

  - by Shirker

  I have entry in my crontab 00 */1 * * * /sbin/mdadm --monitor --scan -1 [email protected] It works more than perfect, but I need to change the default email template. So instead of subject "mdadm monitoring" it wished to be "mdadm monitoring from «IP ADDRESS»" or like that. [root@mail ~]# rpm -ql mdadm-3.2.5-4.el6_4.2.x86_64 | grep -v -E '(man|doc)' /etc/cron.d/raid-check /etc/rc.d/init.d/mdmonitor /etc/sysconfig/raid-check /lib/udev/rules.d/65-md-incremental.rules /sbin/mdadm /sbin/mdmon /usr/sbin/raid-check /var/run/mdadm Is it hardcoded or its possible to change?

• redirect to 404 wildcard subdomain

  - by Leandro Garcia

  I setup a wildcard A record on my domain registrar. Now if a user access a missing subdomain on my domain, they will be redirected to the homepage. Currently my initial setup was this: <VirtualHost *:80> ServerAdmin webmaster@localhost RewriteEngine On RewriteRule ^(.*)$ http://domain.com$1 [R] DocumentRoot /var/www <Directory /> Options FollowSymLinks AllowOverride None </Directory> # more below... </VirtualHost> Any wildcard subdomain or if my IP is entered via URL will redirect to the homepage. Can I do something about this that will redirect (HTTP redirect perhaps) the wildcard subdomains to 404 page instead of to homepage?

• Why can't I change the domain when connecting to network shares in Windows 8?

  - by Nathan Osman

  I have a computer running Windows 8.1 Pro. I also have Ubuntu 12.04.3 Server running within Hyper-V on the same machine. The Ubuntu server has Samba installed. Both the host and guest OS are connected to the workgroup WORKGROUP. When I open up "Network" in Windows 8.1 and attempt to connect to the server (both by name and IP address), I receive the following prompt: Entering the correct username and password for an account on the server fails. /etc/samba/smb.conf has the following share definitions set: [homes] comment = Home Directories browseable = no

• Problem with shared ssh keys

  - by warren

  Following the process I've used in other environments, I've tried setting-up shared keys between my Mac and my CentOS 4 webserver. I've seen the same problem with my older Ubuntu 7.10 workstation trying to connect via keys to the same webserver. I have tried both dsa and rsa keytypes (sshkeygen -t <type>). The sshd_config file on my webserver seems to be allowing key-based logins: RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile .ssh/authorized_keys And my .ssh/authorized_keys has my dsa and rsa keys added. Where should I be looking for what to change next to make key-based logins "Just Work™"? Is it related to the line, #UseDNS yes and sshd is trying to do a reverse-lookup on my IP, but cannot because it's NAT'd?

• Flexible traffic & bandwidth monitor

  - by BrNathan

  I have looked around, but have not found anything to meet our needs. I need something that can log all connections & bandwidth consumption. We need it for analysis: by protocol, source IP (& MAC if possible), destination, etc. Ideally we are looking for something that can produce custom graphs & also uses mysql. All connections go through one server on a bridged connection (2 network cards) so it is easy to pickup traffic. We are not concerned so much with internal LAN traffic as what passes in & out to the firewall. Thanks for you suggestions. Update: I use Ubuntu 10.04

• Dual Home HP Server running Win2003

  - by Colm

  Hello everyone. I'm new to server dual homing. I have a HP ProLiant DL360 G4p running Win2003 with 2 NICs , only one is currently active. I'd like to activate the 2nd NIC connected (in a active/passive state) to a 2nd switch with only one IP address and ideally only one mac layer address. The 1st switch is a Cisco 2960G and the 2nd is a Cisco C3560G. There are VLANS, RSTP and PAGP in use already. Can someone give me an idea, in broad terms , of what technology/protocols I should be investigating (HSRP, SLB Teaming etc.) ? I can provide more info if needed. Thanks, Colm.

• VM can't connect to outside in bridged mode

  - by Kamal

  I am not able to ping any machine(not even the host) from Guest VM in bridged mode. But I got an IP which is on the same subnet as host. I can ping my guest VM from the host and can use ssh to connect to the guest. I am using Vmware workstation 6.5. Guest VM is a centos VM and host is windows xp. Every thing works fine in NAT mode. Any clues as to what could be happening. I tried disabling all the firewalls I have.

• Nginx virtual server only partially working with Java application

  - by MFB

  Final Cut Server is a Java application (made by Apple) which launches from a web page. I have Nginx in front of this web server (amongst others) and, whilst the web server can be browsed externally, the Java app fails to launch correctly and throws the errors below.

• Windows 2008 RRAS and PPPoE

  - by Massimo

  I'm trying to use Windows Server 2008's Routing and Remote Access Server to share an ADSL connection which uses PPPoE, but I'm having no luck. I can setup the connection as a broadband Internet connection in Windows, and it works. I can share it using Internet Connection sharing, and it works (but it's not what I need). I have installed and enabled the Routing and Remote Access Service and configured it for NAT with a demand-dial interface; I create the aforementioned interface using PPPoE with the exact same parameters used on the Windows connection; I connected it, and it seems to work: I can also see it gets its public IP address and DNS assigned correctly. But it just doesn't work. The server has no Internet connectivity at all, and PINGing anything on the Internet results in a cryptic "general error". Any help?

• Cisco vlan entry missing in vlan.dat, but appears in running-config

  - by nLinked

  One of our vlan's (ID: 104) stopped working suddenly and computers on that vlan failed when trying to obtain a dhcp ip address. On the Cisco switch if we do show vlan, this command is supposed to shows the vlans in the vlan.dat file. We notice it has every other vlan except the one that is now missing. If we show the running-config or even the startup config, they DO show the missing vlan (as if everything is fine), but that vlan doesn't take effect. We tried deleting the "missing" vlan using clear vlan 104, but it says No subinterface configured for vLAN Identifier 104, so it's already missing. Recreating the vlan, saving and rebooting still doesn't add it into the vlan.dat or make the vlan work. The switch is in vtp server mode. Our startup config is here: http://pastebin.com/RHxxTG5p Any ideas appreciated.

• Securing data sent to an unencrypted WiFi AP

  - by David Parunakian

  The business plan of a project I'm involved in assumes selling certain WiFi-enabled devices to end users. All these devices originally have an unencrypted connection and a standard SSID. The problem is that although the user can connect to it and set both a new SSID and a WPA passphrase, these are being sent to the AP in plain text and thus can be intercepted by anyone nearby with a sniffer. What's the best solution to this problem, and why? Initially set up an encrypted wireless network at the device and supply the user with a printed passphrase Buy an SSL certificate for the AP's default IP address or local domain name (the APs aren't supposed to work as a router and have a captive portal & dnsmasq installed, so all of them can pretend to be myunit.example.com, as far as I understand) Something different Thank you.

• linux dns server

  - by Clear.Cache

  Can someone explain to me how to easily setup a centos 5 (64bit) dns server? I want to use this strictly for dns for my clients who require rdns (ptr) for their domains. I do have IP delegation/authority from the data center and allocated IPs directly from ARIN. I just want to setup a Centos 5 box to use strictly as a dns server, perhaps with redundancy with a secondary, clustered (or not) dns server Server 1 = dns1.mycompany.com Server 2 = dns2.mycompany.com Then, I need simply instructions on how to create rdns records for clients upon request, especially in bulk amounts. Thank you.

• Securing a Windows Server 2008 R2 Public Web Server

  - by Denny Ferrassoli

  I'm setting up a public web server: Windows Server 2008 R2, IIS7.5. Does anyone have a tutorial / walkthrough / tips on properly securing a public web server? I've seen a few tutorials but mostly focused on Windows Server 2003. What I've done so far: Created a specific user account for the website / app pool, Renamed Admin account, Installed FTPS, Configured firewall to block any non-public service (web / https), Configured firewall to allow access to management interfaces only from specific IP addresses (rdp, IIS management, ftp) Maybe a few other things but can't remember at the moment... ICMP is allowed... Should I disable all except ping? Port scan reveals only web and https ports. Any other suggestions? Thanks

• tcpdump selective acknowledgements question

  - by wlaus

  Hi All, I eventually sometimes watch most initial tcp connection attempts like this: tcpdump -nn -Z somepcapuser not src host (12x.x5.109.xxx or 62.75.160.xxx ) and not (port 9001 or 443 or 8080 ) and tcp[tcpflags]&(tcp-syn) !=0 and not tcp[tcpflags]& (tcp-ack) !=0 or icmp this works pretty well to quickly identify oddness so far. However, I now have a question on the following output: 03:53:52.227884 IP 203.81.166.20.53786 62.75.160.xxx.80: S 846930886:846930886(0) win 61690 "<"mss 1460,nop,nop,sackOK,opt-178:f04700000000,nop,wscale 4"" I wonder what the marked portion means, haven't seen that before.

• Mac Mini's internet very slow, every other device fine (PC, iPhone, Xbox 360)

  - by alex

  I recently haven't used my Mac Mini for about 5 days (however it was left on). I seem to be able to connect and get great download / upload speeds through my PC, Xbox 360, iPhone and parents' laptop. However, my Mac Mini is very slow. OS X's Mail.app is downloading mail at 0.4kbps and then dropping to 0. Skype file transfers are doing the same. Browsing the net is a terrible experience. It is taking 30 seconds or more to download basic pages. All of my devices connect wirelessly to a Netgear router / modem. I have tried giving the Mac Mini a manual IP, and renew DHCP lease, as well as flush DNS in Terminal. I have also rebooted the router / modem twice, and the Mac Mini twice. Do you know what could be causing this? Thanks

• Redhat with a reverse proxy, a specific configuration

  - by jessica

  The setup I am trying to put together consists on a server connected to the internet (a redhat box) and 2 Apache Tomcat boxes not connected to the internet. Let's call the server Server and the two Apache Tomcats, Apache1 and Apache2. So, assuming my external IP is 102.1.1.1, Apache1 is 10.1.1.1 and Apache2 is 10.1.1.2, what I'm trying to configure is a reverse proxy so that if the request goes into http://102.1.1.1/mywebserver1/ it will be directed to Apache1 and if the request goes into http://102.1.1.1/mywebserver2/ it will be forwarded to Apache2. Now, I don't need a cache on the proxy since there is application sitting in those tomcats and each request needs to get a fresh answer. I searched for a while and I tried building this with Squid but i can't get it to work the way I need it. Anyone knows how to do this? What software do I need? How do I configure the reverse proxy? Thanks! jessica

• Gradually migrate from one SMTP server to another

  - by Bart van Wissen

  I maintain an application that sends out a ton of e-mail on a daily basis. Soon, we will have to migrate to another SMTP-server for that, which has an ip address that has no reputation with respect to email delivery. So instead of just flipping the switch, I would like to start by sending a small percentage of all mail through the new server, and then gradually increase that percentage until we reach 100%. It wouldn't be very hard to implement something in the application itself, but I would like to know if there is an easier, more reliable out-of-the-box-type solution for this. My first thought was to use round-robin DNS for this, but the servers require different credentials, use different protocols (one uses SASL, the other doesn't) and even different port numbers, so I think that rules out the DNS based solution. Is there any way, for example, to configure Postfix to send 1 out of x e-mails to relay host A and the rest to relay host B? Or perhaps a different MTA?

• DNS Server Spoofed Request Amplification DDoS - Prevention

  - by Shackrock

  I've been conducting security scans, and a new one popped up for me: DNS Server Spoofed Request Amplification DDoS The remote DNS server answers to any request. It is possible to query the name servers (NS) of the root zone ('.') and get an answer which is bigger than the original request. By spoofing the source IP address, a remote attacker can leverage this 'amplification' to launch a denial of service attack against a third-party host using the remote DNS server. General Solution: Restrict access to your DNS server from public network or reconfigure it to reject such queries. I'm hosting my own DNS for my website. I'm not sure what the solution is here... I'm really looking for some concrete detailed steps to patch this, but haven't found any yet. Any ideas? CentOS5 with WHM and CPanel. Also see: http://securitytnt.com/dns-amplification-attack/

• Squid 3 reloading makes it stop serving requests

  - by coredump

  So, we use Squid 3 here (3.0.STABLE8-3+lenny4), pretty standard configuration (no dansguardian or similar) + NTLM authentication with LDAP background, circa 1000 users on a busy day, and our acls reference some external files (allowed/blocked sites/ip addresses). On Squid 2.X we used to be capable of reloading it's configuration (to add or sites or addresses to rules, etc) and squid would not stop serving during the reload. Since we changed to 3.0, that seems to be impossible: everytime we use reload (or -k reconfigure) it stop serving requests for as long as 2 minutes, and clients receive a Configured proxy is not accepting connections message. I checked the documentation and got nothing about it, does anyone else suffer from this problem or is it a isolated case on my setup? Also, if you have Squid 3.0 and doesn't suffer from this problem, how is your squid configured?

• Spanning-tree setup with incompatible switches

  - by wfaulk

  I have a set of eight HP ProCurve 2910al-48G Ethernet switches at my datacenter that are set up in a star topology with no physical loops. I want to partially mesh the switches for redundancy and manage the loops with a spanning-tree protocol. However, our connection to the datacenter is provided by two uplinks, each to a Cisco 3750. The datacenter's switches are handling the redundant connection using PVST spanning-tree, which is a Cisco-proprietary spanning-tree implementation that my HP switches do not support. It appears that my switches are not participating in the datacenter's spanning-tree domain, but are blindly passing the BPDUs between the two switchports on my side, which enables the datacenter's switches to recognize the loop and put one of the uplinks into the Blocking state. This is somewhat supposition, but I can confirm that, while my switches say that both of the uplink ports are forwarding, only one is passing any real quantity of data. (I am assuming that I cannot get the datacenter to move away from PVST. I don't know that I'd want them to make that significant of a change anyway.) The datacenter has also sent me this output from their switches (which I have expurgated of any identifiable info): 3750G-1#sh spanning-tree vlan nnn VLAN0nnn Spanning tree enabled protocol ieee Root ID Priority 10 Address 00d0.0114.xxxx Cost 4 Port 5 (GigabitEthernet1/0/5) Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Bridge ID Priority 32mmm (priority 32768 sys-id-ext nnn) Address 0018.73d3.yyyy Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Aging Time 300 sec Interface Role Sts Cost Prio.Nbr Type ------------------- ---- --- --------- -------- -------------------------------- Gi1/0/5 Root FWD 4 128.5 P2p Gi1/0/6 Altn BLK 4 128.6 P2p Gi1/0/8 Altn BLK 4 128.8 P2p and: 3750G-2#sh spanning-tree vlan nnn VLAN0nnn Spanning tree enabled protocol ieee Root ID Priority 10 Address 00d0.0114.xxxx Cost 4 Port 6 (GigabitEthernet1/0/6) Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Bridge ID Priority 32mmm (priority 32768 sys-id-ext nnn) Address 000f.f71e.zzzz Hello Time 2 sec Max Age 20 sec Forward Delay 15 sec Aging Time 300 sec Interface Role Sts Cost Prio.Nbr Type ------------------- ---- --- --------- -------- -------------------------------- Gi1/0/1 Desg FWD 4 128.1 P2p Gi1/0/5 Altn BLK 4 128.5 P2p Gi1/0/6 Root FWD 4 128.6 P2p Gi1/0/8 Desg FWD 4 128.8 P2p The uplinks to my switches are on Gi1/0/8 on both of their switches. The uplink ports are configured with a single tagged VLAN. I am also using a number of other tagged VLANs in my switch infrastructure. And, to be clear, I am passing the tagged VLAN I'm receiving from the datacenter to other ports on other switches in my infrastructure. My question is: how do I configure my switches so that I can use a spanning tree protocol inside my switch infrastructure without breaking the datacenter's spanning tree that I cannot participate in?
