• Java Swing over Remote Desktop - Strange, weird GUI squashing

  - by ADTC

  I thought this question fits SuperUser more than StackOverflow because it's not about actual Java programming, though programmers might be more likely to encounter the problem. Anyway, let me start of with some stats before I ask the actual question: Laptop: Windows 7 x32 Screen resolution 1024 x 768; Nvidia GeForce Go 6200 Connected to desktop via ad-hoc wireless network Access internet via desktop Desktop: Windows 7 x64 Screen resolution 1920 x 1080 Connected to laptop via ad-hoc wireless network Access internet via cable modem I'm connecting to my laptop via Remote Desktop from my desktop to take advantage of the large screen. I'm doing programming on my laptop (for portability reasons). Everything else runs smooth and fast over Remote Desktop as both computers are connected directly over the ad-hoc wireless. The only problem is this: Java Swing apps don't display the GUI properly. I acquired a Java Swing application and I'm debugging it in Eclipse. Here's what I got when I ran the app: Apparently there doesn't seem to be anything wrong with the GUI application I'm debugging, because the Java Control Panel exhibits the same problem. I've searched high and low in Google about this; the closest I came to a solution is this. But sadly, the use of -Dsun.java2d.nodraw=true has no effect at all. This only happens over Remote Desktop. I have tried locally and the GUI apps display properly. This isn't a dealbreaker for me as I can stop using Remote Desktop when developing Java Swing apps. However, I would like to know if anyone has encountered this and found any solution. PS: All software involved (Eclipse, Java JRE, etc.) are latest versions.

• Copy a harddrive from a failed desktop machine using a second working one. [closed]

  - by MrEyes

  Heres the scenario: I have PC-A, an old PC that runs Windows XP but now refuses to boot due to a failed motherboard (or maybe PSU). This PC has a single 80gb IDE drive. I also have PC-B, running Windows Vista, this is working fine. I want to copy all the data off PC-As HDD onto PC-B. To do this I have taken the HDD out of PC-A and connected it as a slave to PC-B. PC-B now boots and sees the additional drive. However, when I attempt to access/copy user folders (i.e. Documents and Settings/[username]/*) I am told that I cannot access the folders due to user permissions. I am doing this under an adminstrator account on PC-B. So the question is, how can I "backup" the data? Preferably without making any changes to the drive contents. The reason for this is that it is possible that PC-A is failing due to a bad PSU, so I intend to replace it before writing off the machine. However I would feel much happier if I had a backup of the data on the HDD.

• Password Cracking Windows Accounts

  - by Kevin

  At work we have laptops with encrypted harddrives. Most developers here (on occasion I have been guilty of it too) leave their laptops in hibernate mode when they take them home at night. Obviously, Windows (i.e. there is a program running in the background which does it for windows) must have a method to unencrypt the data on the drive, or it wouldn't be able to access it. That being said, I always thought that leaving a windows machine on in hibernate mode in a non-secure place (not at work on a lock) is a security threat, because someone could take the machine, leave it running, hack the windows accounts and use it to encrypt the data and steal the information. When I got to thinking about how I would go about breaking into the windows system without restarting it, I couldn't figure out if it was possible. I know it is possible to write a program to crack windows passwords once you have access to the appropriate file(s). But is it possible to execute a program from a locked Windows system that would do this? I don't know of a way to do it, but I am not a Windows expert. If so, is there a way to prevent it? I don't want to expose security vulnerabilities about how to do it, so I would ask that someone wouldn't post the necessary steps in details, but if someone could say something like "Yes, it's possible the USB drive allows arbitrary execution," that would be great! EDIT: The idea being with the encryption is that you can't reboot the system, because once you do, the disk encryption on the system requires a login before being able to start windows. With the machine being in hibernate, the system owner has already bypassed the encryption for the attacker, leaving windows as the only line of defense to protect the data.

• Server 2008 NAT Internet Not Working

  - by Jack

  I'm trying to set up Routing and Remote Access on Windows Server 2008 R2, I have a network connection that I want to share the internet from to another private network. The server has two NICs which are configured as follows: External NIC (Dynamically assigned by ISP) IP:10.175.4.150 Subnet:255.255.192.0 Gateway:10.175.0.1 DNS:10.175.0.1 Internal NIC IP:172.16.254.1 Subnet:255.255.255.0 Gateway:None DNS:None I have set the external NIC to be the public interface and enabled NAT on it in the RRAS MMC and set the internal NIC to be a private interface. I have also set up the DNS forwarding or whatever it is in the NAT section. From a client (IP:172.16.254.2) I can ping the server and access files on it, when I try to browse the web with the default gateway set to the internal NIC ip I end up getting a 404 page which is returned from the ISPs default gateway. I'm guessing it's something to do with the double NAT possibly. Trying to ping the ISPs default gateway from a private network client just times out as does accessing it directly. I've disabled and reconfigured RRAS multiple times and that doesn't seem to have made a difference, so can anyone tell me what I'm doing wrong? Thanks.

• Network Explorer Intermittently Fails to Display all Computers in Work Group

  - by graf_ignotiev

  I run a small computer lab of 10 computers and occasionally, when using the network explorer (a.k.a Network Browser) some or all of the remote computers will fail to appear. If I try to access a remote computer by its name I get an unspecified error (code 0x80004005), but I am still able to access it with the computer's IP address. The strangest part is that the problem will inexplicably go away after waiting awhile. Each computer is running Windows 7 x64 Enterprise and has identical hardware, software and configuration. They are all on the same subnet and in the same workgroup. I've spent days researching the problem and have tried the following solutions: Updated the BIOS, chipset and network adapter drivers Changed Power Settings in Network Adapter Properties so that the computer will not turn it off Disabled the Computer Browser service Changed the DHCP node type to broadcast Reviewed the Event Viewer logs Steps 3 and 4 have seemed to help the problem a little bit, but not completely. I'm beginning to suspect that the problem might lie with our router which is a ZyXEL ZyWALL 2WG, as the packets sent by Network Discovery may not be returning in time, but I wanted to get some perspective in the issue before I went any further.

• Windows 2008 R2 AWS CloudFormation Elastic beanstalk configuration

  - by Webmonger

  I'm looking for some configuration advice. I have a need for a load balanced windows environment with shared media across all instances that are hosting the app. The best explanation i can give is that there will be multiple Windows 2008 server with IIS hosting the app going through an ELB to load balance. Users must be able to upload content (images, video etc...) to the site that will be hosted. When a user uploads media it needs to be kept on a shared location so all windows IIS instances can access the files, I can't host the files on S3 because of the app architecture so they need to be in a place where all IIS server will have access. In addition I need to run an update each IIS server instance that updates a local memory cache when SQL data is updated. I was thinking of a configuration like this: [ELB] - [Win 2008 IIS (multiple servers)] - [Win 2008 File & SQL Server(possibly RDS?)] Does this configuration make sense? If not could you provide an idea of how I should configure it. Thanks in advance

• Struggling to set-up NLB cluster

  - by Chris W

  I'm trying to set up NLB on a couple of Windows 2008 R2 virtual servers running on top of Hyper V R2. The servers each have a single vNIC for LAN access (and a second vNIC for SAN access). I'm setting up the cluster to use Multicast mode. The vNICs are each set to allow MAC spoofing. Essentially I'm finding that i can add SERVER1 as a host and it will pick up and respond to the cluster IP from a remote subnet. If I then 'stop' the node in NLB manager it still responds when I would expect it to stop answering on that IP. If I recreate the cluster and add SERVER2 as the first host, the wizard completes correctly and an IPCONFIG on the server shows that it now has the cluster IP but I can't ping the cluster IP from a remote subnet but I can from another machine on the same subnet. As a final test - with both servers in the cluster, pinging from another machine on the same subnet I still get a response from the cluster IP when both nodes are stopped according to the NLB manager. The two VMs are sat on the same physical blade and are built up exactly the same as they'll be used as SharePoint web front end servers. I'm at a loss as to what could be wrong with the second VM that prevents it taking on the address just as the sole node in the cluster, never mind the strange behaviour of the cluster when I stop/start nodes.

• Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

  - by Richard Lefebvre

  It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011

• How to enable error log in lighttpd properly?

  - by Tomaszs

  I have a Centos 5 system with Lighttpd and fastcgi enabled. It does log access but does not log errors. I have Internal Server Error 500 and no info in log and when I try to open not -existing file also - no info in error log. How to enable it properly? Below is list of modules that I've enabled: server.modules = ( "mod_rewrite", "mod_redirect", "mod_alias", # "mod_access", # "mod_cml", # "mod_trigger_b4_dl", # "mod_auth", "mod_status", "mod_setenv", "mod_fastcgi", # "mod_webdav", # "mod_proxy_core", # "mod_proxy_backend_fastcgi", # "mod_proxy_backend_scgi", # "mod_proxy_backend_ajp13", # "mod_simple_vhost", # "mod_evhost", # "mod_userdir", # "mod_cgi", # "mod_compress", # "mod_ssi", # "mod_usertrack", # "mod_expire", # "mod_secdownload", # "mod_rrdtool", "mod_accesslog" ) Here are setting of debugging: ## enable debugging #debug.log-request-header = "enable" #debug.log-response-header = "enable" #debug.log-request-handling = "enable" debug.log-file-not-found = "enable" #debug.log-condition-handling = "enable" Setting of path to error and access log: ## where to send error-messages to server.errorlog = "/home/lxadmin/httpd/lighttpd/error.log" #### accesslog module accesslog.filename = "/home/lxadmin/httpd/lighttpd/ligh.log" Settings of fastcgi: fastcgi.debug = 1 fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 12, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "2", "PHP_FCGI_MAX_REQUESTS" => "500" ) ))) And in included config file I have: server.errorlog = "/home/httpd/mywebsite.com/stats/mywebsite.com-error_log" What comes to log files: /home/httpd/mywebsite.com/stats/ -rw-r--r-- 1 apache apache 5173239 May 16 11:34 mywebsite.com-custom_log -rwxrwxrwx 1 root root 0 Mar 27 2009 mywebsite.com-error_log /home/lxadmin/httpd/lighttpd/ -rwxrwxrwx 1 apache apache 2184 Apr 22 22:59 error.log -rwxrwxrwx 1 apache apache 6088621 May 16 11:26 ligh.log I gave error logs chmod 777 for a try to check if it's the issue, but apparently it's not. So my question is: what to do to have error log enabled?

• Setup.exe called from a batch file crashes with error 0x0000006

  - by Alex

  We're going to be installing some new software on pretty much all of our computers and I'm trying to setup a GPO to do it. We're running a Windows Server 2008 R2 domain controller and all of our machines are Windows 7. The GPO calls the following script which sits on a network share on our file server. The script it self calls an executable that sits on another network share on another server. The executable will imediatelly crash with an error 0x0000006. The event log just says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Setup.exe because of this error. Here's the script (which is stored on \\WIN2K8R2-F-01\Remote Applications): @ECHO OFF IF DEFINED ProgramFiles(x86) ( ECHO DEBUG: 64-bit platform SET _path="C:\Program Files (x86)\Canam" ) ELSE ( ECHO DEBUG: 32-bit platform SET _path="C:\Program Files\Canam" ) IF NOT EXIST %_path% ( ECHO DEBUG: Folder does not exist PUSHD \\WIN2K8R2-PSA-01\PSA Data\Client START "" "Setup.exe" "/q" POPD ) ELSE ( ECHO DEBUG: Folder exists ) Running the script manually as administrator also results in the same error. Setting up a shortcut with the same target and parameters works perfectly. Manually calling the executable also works. Not sure if it matters, but the installer is based on dotNETInstaller. I don't know what version though. I'd appreciate any suggestions on fixing this. Thanks in advance! UPDATE I highly doubt this matters, but the network share that the script is hosted in is a shared drive, while the network share the script references for the executable is a shared folder. Also, both shares have Domain Computers listed with full access for the sharing and security tabs. And PUSHD works without wrapping the path in quotes.

• Resources for Smartphone Security

  - by Shial

  My organization is currently working on improving our data and network security due to increasing HIPAA laws and a general need to get a better grasp on controlling our health related information. We are a non-profit working with people with developmental disabilities so we handle a lot of medical related information. One area that has been identified as a risk is our use of smartphones, specifically at this time Windows Mobile 6.1 devices from T-Mobile. We do not utilize the VPNs on the phones so there isn't any way they can access our databases or file servers (username/password for VPNs is not the domain logons). What would be exposed however is the particular user's email account since you could extract out the username/password and access the email either on the device or on our web email (Exchange 2003) which could contain HIPAA protected confidential information about clients and services and this would be an incident that would have to be reported. What resources or ideas would help us secure these devices? I'm not worried about data interception (using SSL) but more about physical theft or loss of the device. Are there websites that I just have not found with guidelines and suggestions or particualar products that would help protect us? I also don't want to limit the discussion to windows Mobile either. I myself am looking at an android 2.0 device and there is always the eventual possibility we could get pushed to enable the VPNs. I know this is a subject that likely won't have any particular correct answer and it is something we should all be aware of since there devices are sitting outside of our immediate control most of the time.

• How have multiple web servers and IPs on the same physical network

  - by jsigned

  I do web development out of a small office and need to have multiple physical and virtual servers that can be accessed from the internet. I also have a number of devices (computers, laptops, tablets, printers, etc) that need connections as well. I have gotten a subnet of 8 IP's from my ISP and while that is adequate for the web servers its far too small for everything that needs access to the network. My router is an ASUS RT-N16 running DD-WRT. I'm just smart enough about this routing topic to be dangerous, think 2 year old with a magic marker. I would like to keep my internal network NAT'ed on the 192.168.x.x network and route the 68.69.x.x 255.255.255.248 traffic directly to the servers. The physical network consists of the 4 port DD-WRT router and an unmanaged gig switch. I have a fiber connection to the office that works as an Ethernet port. In other words I can plug my laptop directly into it and have access to the internet. There is no login or password and the router is setup to get DHCP from the ISP, and to provide DHCP addresses for the internal network. What I've done so far is google and try different configurations with little success. In the end I decided I didn't even know how to ask the questions needed. My questions are: Is this the best way to configure the network? How do you do it? VLANs? Multiple routers? I've never had to configure a router using anything more than the GUI so if this is command line stuff be gentle.

• SQLAuthority News – Who I Am And How I Got Here – True Story as Blog Post

  - by pinaldave

  Here are few of the sample questions I get every day? “Give me shortcut to become superstar?” “How do I become like you?” “Which book I should read so I know everything?” “Can you share your secret to be successful? I want to know it but do not share with others.” There is generic answer I always give is to work hard and read good educational material or watch good online videos. One of the emails really caught my attention. It was from a friend and SQL Server Expert John Sansom (Blog | Twitter). He wrote if I would like to share my story with the world about “Who I am and How I got Here”. I was very much intrigued with his suggestion. John is one guy I respect a lot. Every single topic he writes, I read it with dedication. I eagerly wait for his Weekly Summary of Best SQL Links. If you have not read them, you are missing something out. Writing a guest post for him was like walking in memory lane. I remembered the time when I was beginning my career and I was bit overconfident and bit naive. I had my share of mistakes when I started my career. As time passed by I realize the truth. Well, we all do mistakes. Though, I am proud that as soon as I know my mistakes I corrected them. I never acted on impulse or when I am angry. I think that alone has helped me analysis the situation better and become better human being. During the course, I have lost my ego and it is replaced by passion. I am much more happy and successful in my work. Quite often people ask me if I am always online and wether I have family or not. Honestly, I am able to work hard because of my family. They support me and they encourage me to be enjoy in what I do. They support everything I do and personally, I do not miss a single occasion to join them in daily chores of fun. If there was a shortcut to success – I want know. I learnt SQL Server hard way and I am still learning. There are so many things, I have to learn. There is not enough time to learn everything which we want to learn. I am constantly working on it every day. I welcome you to join my journey as well. Please join me with my journey to learn SQL Server – more the merrier. I have written a story of my life as a guest post.  Read Here: A Journey to SQL Authority Special thanks to John Sansom (Blog | Twitter) for giving me space to talk my story. Indeed I am honored.

• Does Windows 7 Authenticate Cached Credentials on Startup

  - by Farray

  Problem I have a Windows domain user account that gets automatically locked-out semi-regularly. Troubleshooting Thus Far The only rule on the domain that should automatically lock an account is too many failed login attempts. I do not think anyone nefarious is trying to access my account. The problem started occurring after changing my password so I think it's a stored credential problem. Further to that, in the Event Viewer's System log I found Warnings from Security-Kerberos that says: The password stored in Credential Manager is invalid. This might be caused by the user changing the password from this computer or a different computer. To resolve this error, open Credential Manager in Control Panel, and reenter the password for the credential mydomain\myuser. I checked the Credential Manager and all it has are a few TERMSRV/servername credentials stored by Remote Desktop. I know which stored credential was incorrect, but it was stored for Remote Desktop access to a specific machine and was not being used (at least not by me) at the time of the warnings. The Security-Kerberos warning appears when the system was starting up (after a Windows Update reboot) and also appeared earlier this morning when nobody was logged into the machine. Clarification after SnOrfus answer: There was 1 set of invalid credentials that was stored for a terminal server. The rest of the credentials are known to be valid (used often & recently without issues). I logged on to the domain this morning without issue. I then ran windows update which rebooted the computer. After the restart, I couldn't log in (due to account being locked out). After unlocking & logging on to the domain, I checked Event Viewer which showed a problem with credentials after restarting. Since the only stored credentials (according to Credential Manager) are for terminal servers, why would there be a Credential problem on restart when remote desktop was not being used? Question Does anyone know if Windows 7 "randomly" checks the authentication of cached credentials?

• Git push over http (using git-http-backend) and Apache is not working

  - by Ole_Brun

  I have desperately been trying to get push for git working through the "smart-http" mode using git-http-backend. However after many hours of testing and troubleshooting, I am still left with error: Cannot access URL http://localhost/git/hello.git/, return code 22 fatal: git-http-push failed` I am using latest versions of Ubuntu (12.04), Apache2 (2.2.22) and Git (1.7.9.5) and have followed different tutorials found on the Internet, like this one http://www.parallelsymmetry.com/howto/git.jsp. My VHost file currently looks like this: <VirtualHost *:80> SetEnv GIT_PROJECT_ROOT /var/www/git SetEnv GIT_HTTP_EXPORT_ALL SetEnv REMOTE_USER=$REDIRECT_REMOTE_USER DocumentRoot /var/www/git ScriptAliasMatch \ "(?x)^/(.*?)\.git/(HEAD | \ info/refs | \ objects/info/[^/]+ | \ git-(upload|receive)-pack)$" \ /usr/lib/git-core/git-http-backend/$1/$2 <Directory /var/www/git> Options +ExecCGI +SymLinksIfOwnerMatch -MultiViews AllowOverride None Order allow,deny allow from all </Directory> </VirtualHost> I have changed the ownership of the /var/www/git folder to root.www-data and for my test repositories I have enabled anonymous push by doing git config http.receivepack true. I have also tried with authenticated users but with the same outcome. The repositories were created using: sudo git init --bare --shared [repo-name] While looking at the apache2 access.log, it appears to me that WebDAV is trying to be used, and that git-http-backend is never fired: 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "GET /git/hello.git/info/refs?service=git-receive-pack HTTP/1.1" 200 207 "-" "git/1.7.9.5" 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "GET /git/hello.git/HEAD HTTP/1.1" 200 232 "-" "git/1.7.9.5" 127.0.0.1 - - [20/May/2012:23:04:53 +0200] "PROPFIND /git/hello.git/ HTTP/1.1" 405 563 "-" "git/1.7.9.5" What am I doing wrong? Is it an issue with the version of git and/or apache that I am using perhaps? BTW: I have read all the git http related questions on ServerFault and StackOverflow, and none of them provided me with a solution, so please don't mark this as duplicate.

• How to setup an IPSec / GRE tunnel on Windows Server 2008

  - by qbeuek

  I have a Windows Server 2008 that has a single network interface configured with a public IP address. My business partner has a private network. From my server, I need to access all the devices on his private network, and those devices must be able to access my server. My business partner has a standard solution for these requirements. They will setup an IPSec + GRE tunnel to my server. They told me, that I will need an additional public IP address for this to work. If it really is necessary, there is no problem, I can get an additional public IP address, although it will be assigned to the same physical network interface. I assume that on my server I will have both public IP addresses and also the private IP address from the tunnel (the same that is visible for the devices inside the private network). What alternatives do I have? Is it possible to configure this tunnel on my Windows Server 2008? Can it be done using only Windows tools, or do I need an additional free / commercial VPN software? If it cannot be done directly on Windows, can I setup an additional virtual machine running Linux, that will handle the IPSec + GRE tasks? How to do it? If it cannot be done on a virtual linux box, will I have to buy and setup a Cisco router to handle the IPSec + GRE tasks? Thanks for your opinions. I'm watching this question to clarify any issues or questions.

• Networking - intermittent, slow speeds

  - by jack

  Hi all I'm a novice when it comes to networking. I live in a large two storey building that used to be a school and we have an internet connection with BT (british telecoms provider), the connection speed is 12Mb.. Basically our connection is slow and very intermittent and I was wondering if anybody here could provide some help or ideas. There are about 11 people in the building who could be online at any time. We have a router on the ground floor which is bog standard supplied by BT. To provide Broadband access to the 1st and 2nd floors, we used an old switch that the school left, we have a cable running from the router on the first floor to the switch which connects to a wireless router which is configured as a bridge on the 2nd floor supplying broadband access to the 1st and 2nd floors. Additionally we have 3 computers that are connected via the switch through the ethernet sockets left by the school on the ground floor. The router we use on the 2nd floor came in a pack of 2 and cost about £15 (bought by another person). Sometimes the connection is perfectly fine, i.e. early hours of the morning or when everybody is out, we have rang BT who say that the connection cannot cope with the numbers of people online, plus I'm not sure whether each person is streaming etc. Can anybody offer any advice?

• Some URLs fail to load on Windows web portal

  - by jpolache

  I’m working in a large data center and have been assigned to troubleshoot and issue with a windows (IIS) web server that acts as a portal for a customer of the data center. This portal server is on a DMZ at the local data center. I don’t have access to the portal desktop and am relying on an off-site administrator to work with me to do testing and report the condition of the portal. He tells me there are no software firewalls or other filtering configured. While most of the remote web pages work fine, several of the URSs the portal is suppose to serve up fail to load. I had wireshark installed on the portal system and had a capture taken of one of the failures. I used IE to access one of the remote web servers at issue. I could see the TCP SYN-ACK coming back from the remote server, but after several HTTP GETs fail to get a response the portal server sends a reset. The webmaster of the remote web server assures me that no sites are being blocked. I had a capture taken outside the local firewall, so there should be no issue there. Another tech set up a laptop and used the IP address of the portal (we took the portal off-line for the test). The laptop loads the URL as expected. I tried having Firefox loaded to make sure that the HTTP GET was not mal-formed. Same failure as with IE. So, it seems it is not the remote web server or the network, because there was no problem with the laptop. At this point, I’m not sure what other questions to ask or tests to do.

• How can adding a server to a domain cause Remote Desktop to stop working?

  - by Adrian Grigore

  I have two dedicated with Windows 2008 R2 servers which I am using for Web hosting. One Server A is a domain controller, Server B should simply be added to the domain controlled by Server A. So I RDP'd into Server B and changed the system settings so that Server B is part of that domain. I entered my domain admin credentials, was welcomed to the domain and asked to reboot the server. So far everything seemed to work smoothly After rebooting, I could not open an RDP connection to Server B anymore: Remote Desktop can’t connect to the remote computer for one of these reasons: 1) Remote access to the server is not enabled 2) The remote computer is turned off 3) The remote computer is not available on the network Make sure the remote computer is turned on and connected to the network, and that remote access is enabled. I restored an older backup of Server B and switched off the firewall before adding the server to my domain. But the problem reoccurred just the same. What could be the reason for this? The domain is brandnew and I did not change any of the default settings. Could this be some kind of domain-wide default policy that shuts down RDP on any domain clients? Or perhaps it has to do with the fact that Server B is virtual? Thanks for your help, Adrian

• Windows 7 - Windwos XP - sharing - why isn't working?

  - by durumdara

  Hi! This is seems to be "hardware" and not "software" / "programming" question, but I need to use this share in my programs, so it is "close to programming". We had an XP based wireless network. The server is XP Professional, the clients are XP Home (Notebooks). This was working well with folder sharing (with user rights, not simple share). Then we replaced the one of the notebook with Win7/X64 notebook. First time this can reach the server, and the another client too. Later I went to another sites, and connect to another servers, another networks. And then, when I return to this network, I saw that I cannot connect to this server. Nothing of resources I see, and when try to dbl click on this computer, I got login window, where I can write anything, never I can login... The interesting part, that: Another XP home can see the server, can login as quest, or with other user. The server can see the XP home notebook. The Win7 can see the notebook's shared folders, and XP home can see the Win7 shared folders. The server can see the Win7 folders, BUT: the Win7 cannot see the server folders. Cannot see the resources too... The Win7 is in "work networking group", the group name is not mshome. I tried everything on the server, I tried to remove MS client, restore it with simple sharing, set guest password, etc., but I lost the possibilities to access this server from Win7. Does anyone have any idea what I need to see, what I need to set to access these resource - to use them in my programs? Thanks for every info, link: dd

• Google-Bot fell in love with my 404-page

  - by 32bitfloat

  Every day my access-log looks kind of this: 66.249.78.140 - - [21/Oct/2013:14:37:00 +0200] "GET /robots.txt HTTP/1.1" 200 112 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.78.140 - - [21/Oct/2013:14:37:01 +0200] "GET /robots.txt HTTP/1.1" 200 112 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.78.140 - - [21/Oct/2013:14:37:01 +0200] "GET /vuqffxiyupdh.html HTTP/1.1" 404 1189 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" or this 66.249.78.140 - - [20/Oct/2013:09:25:29 +0200] "GET /robots.txt HTTP/1.1" 200 112 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.75.62 - - [20/Oct/2013:09:25:30 +0200] "GET /robots.txt HTTP/1.1" 200 112 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" 66.249.78.140 - - [20/Oct/2013:09:25:30 +0200] "GET /zjtrtxnsh.html HTTP/1.1" 404 1186 "-" "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)" The bot calls the robots.txt twice and after that tries to access a file (zjtrtxnsh.html, vuqffxiyupdh.html, ...) which cannot exist and must return a 404 error. The same procedure every day, just the unexisting html-filename changes. The content of my robots.txt: User-agent: * Disallow: /backend Sitemap: http://mysitesname.de/sitemap.xml The sitemap.xml is readable and valid, so there seems to be no reason why the bot should want to force a 404-error. How should I interpret this behaviour? Does it point to a mistake I've done or should I ignore it?

• DNS NAmeserver Aname and cname records

  - by David

  Hi - I am inexperienced in the configuration of DNS and have an issue with dominan hosting set up. I have two domains 'www.mydomain1.com' and 'www.mydomain2.com', with mydomain2 pointed at the same place as mydomain1. The domains were passed to me recently by the person who previoulsy controlled them. I have an account with fasthosts in the uk. When I accepted the domains I could not access the DNS settings and enquired with fasthosts as to why. The replied saying 'The delegate hosting option for both domains were enabled and this is the reason why you were unable to find the option to edit the advanced DNS records. I have now disabled the delegate hosting option so you can now edit the advanced DNS records for both domains in your account.' When i log into the fasthost control panel now i can access the DNS controls but both domains have no A Record of Cname record set up. I am concerned that fasthosts have blatted the previous Nameserver entries and set me up on theirs but not added any record. 'www.mydomain1.com' currently still works but 'www.mydomain2.com' does not find the site anymore. i am worried i will lose mydomain1 to as teh dns changes filter through the system. my webhosting is at 'xxx.xxx.xxx.xxx/mydomain1.com/' and this is where I want both domains to point. Any advice would be much appreciated. one thing which is confusing me is that because I am on a shared server I have to put 'xxx.xxx.xxx.xxx/mydomain1.com/' to get to my site rather than just 'xxx.xxx.xxx.xxx'. The form on fasthosts for the aname record only allows an IP to be entered - does it add the mydomain1.com/ onto the end itself? Thanks for any help given - I'm quite worried about this David

• Running a VM off a USB 2.0 Flash Drive - Mac/Parallels/XP

  - by geerlingguy

  I use a MacBook Air as my primary machine, and the 128GB SSD means space is precious. To save about 10 GB, I've been running Parallels with a Windows XP VM off an external USB hard drive, which performs as well in everyday use as running the VM off the internal SSD. So, I bought a tiny 32GB USB 2.0 flash drive, plugged it into the MacBook Air, formatted it first as ExFAT (which was slow), then as Mac OS Extended (Journaled) (which was also slow), and copied over my VM file, and ran Parallels off it. My full experience is documented here: http://www.midwesternmac.com/blogs/jeff-geerling/running-windows-xp-vm Straight file copies are really fast — 30 MB/sec read (solid the whole time), and 10-11 MB/sec write (solid the whole time). But I noticed that once XP started running, the disk access rates were in the low KB ranges. Are USB flash drives really that poor at random access, or could I possibly be missing something (the format of the flash drive, etc.?)? Of note, I've tried the following, to no great effect: Formatting the drive as either ExFAT or Mac OS Extended (Journaled) Unplugging all other USB devices and turning off Bluetooth (which runs on the right-side-port USB bus). Plugging in the flash drive either direct in the right side port, or the left side port, or into a USB 2.0 hub
