• uninstall google chrome in fedora

  - by tbleckert

  Yesterday I installed Fedora 15 Beta with GNOME 3 - it works well. One problem though is that I installed Chrome 32-bit (which was wrong, should have been the 64-bit version) and now I can't uninstall it. I can't find it in Add/Remove Software, and I also can't install the correct version of Chrome because it complains about my other copy of Chrome. Any ideas how I can remove the existing copy and get the 64-bit version installed? Here's the message I get when trying to install: Test Transaction Errors: file /etc/cron.daily/google-chrome from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/chrome from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/chrome-sandbox from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/libffmpegsumo.so from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/libpdf.so from install of google-chrome-stable-11.0.696.65-84435.x86_64 conflicts with file from package google-chrome-stable-11.0.696.65-84435.i386 file /opt/google/chrome/libppGoogleNaClPluginChrome.so from install of google-chrome-stable-11.0.696.65-84435.x8...

• Nginx case-insensitive reverse proxy rewrites

  - by BrianM

  I'm looking to setup an nginx reverse proxy to make some upcoming server moves and load balanced implementations much easier within our apps. Since our servers are all IIS case sensitivity hasn't been an issue, but now with nginx it's becoming one for me. I am simply looking to do a rewrite regardless of case. Infrastructure notes: All backend servers are IIS Most services are WCF services I am trying to simplify the URLs so I can move services around as we continue to build out I can't set my location to case insensitive due to the following error: nginx: [emerg] "proxy_pass" cannot have URI part in location given by regular expression, or inside named location, or inside "if" statement, or inside "limit_except" block in /etc/nginx/sites-enabled/test.conf:101 The main part of my conf file where I am trying to handle the rewrite is as follows location /svc_test { proxy_set_header x-real-ip $remote_addr; proxy_set_header x-forwarded-for $proxy_add_x_forwarded_for; proxy_set_header host $http_host; proxy_pass http://backend/serviceSite/WFCService.svc; } location ~* /test { rewrite ^/(.*)/$ /svc_test/$1 last; } It's the /test location that I can't get figured out. If I call http://nginxserver/svc_test/help I get the WCF help page to display correctly and I can make all available REST calls. This HAS to be a boneheaded regex issue on my part, but I have tried several variations and all I can get are 404 or 500 errors from nginx. This is NOT rocket science so can someone point me in the right direction so I can look like an idiot and just move on?

• WebLogic embedded LDAP crashes

  - by Spiff

  Our production admin server (WebLogic 10.3.5 running on Solaris 10) crashes from time to time. Logs show tons of these errors (several each minute): <1-Jun-2012 2:28:34 o'clock AM EDT> <Critical> <EmbeddedLDAP> <BEA-000000> <java.lang.NullPointerException at weblogic.socket.DevPollSocketMuxer.cleanupSocket(DevPollSocketMuxer.java:150) at weblogic.socket.DevPollSocketMuxer.cancelIo(DevPollSocketMuxer.java:166) at weblogic.socket.SocketMuxer.deliverExceptionAndCleanup(SocketMuxer.java:836) at weblogic.socket.SocketMuxer.deliverEndOfStream(SocketMuxer.java:760) at weblogic.ldap.MuxableSocketLDAP$LDAPSocket.close(MuxableSocketLDAP.java:128) at com.octetstring.vde.Connection.close(Connection.java:166) at com.octetstring.vde.WorkThread.executeWorkQueueItem(WorkThread.java:89) at weblogic.ldap.LDAPExecuteRequest.run(LDAPExecuteRequest.java:50) at weblogic.work.SelfTuningWorkManagerImpl$WorkAdapterImpl.run(SelfTuningWorkManagerImpl.java:528) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:209) at weblogic.work.ExecuteThread.run(ExecuteThread.java:178) Eventually, the admin server runs out of memory: <1-Jun-2012 12:29:59 o'clock PM EDT> <Error> <Kernel> <BEA-000802> <ExecuteRequest failed java.lang.OutOfMemoryError: GC overhead limit exceeded. One does not necessarily cause the other, but it seems like a pretty good fit. When inspecting the WebLogic code, we see this: void cleanupSocket(MuxableSocket paramMuxableSocket, SocketInfo paramSocketInfo) { this.sockRecords[paramSocketInfo.getFD()] = null; // DevPollSocketMuxer.java:150 super.cleanupSocket(paramMuxableSocket, paramSocketInfo); } protected void cancelIo(MuxableSocket paramMuxableSocket) { super.cancelIo(paramMuxableSocket); cleanupSocket(paramMuxableSocket, paramMuxableSocket.getSocketInfo()); // DevPollSocketMuxer.java:166 } So paramMuxableSocket.getSocketInfo() would be null. I'm at a loss for explaining this... Anyone have an idea? Thanks!

• Gnome-Applets Package Causing Gnome to Segfault

  - by FranticPedantic

  When I boot ubuntu I get a bunch of windows saying "The panel encountered a problem while loading: OAFIID:GNOME_ShowDesktopApplet", with a bunch of others(5) besides ShowDesktopApplet. I am able to launch a terminal, and I do have the taskbar at the top, although the bar at the bottom that holds the windows is blank, so when I minimize a window it disappears. Furthermore, when I try to launch most applications (firefox for example) it segfaults. I have googled the error but it seems to be common but general issue, and a lot of the solutions that worked for others didn't work for me. I tried deleting the gconf, gnome, and gnome2 folders in my home directory. I tried deleting a bunch of the gnome folders (although I might have done this wrong, I was confused as to which ones). I have also tried to use apt-get and dpkg to re-install ubuntu-desktop and gnome-applets. However, when I try apt-get install ubuntu-desktop I get errors regarding /var/cache/apt/archives/gnome-applets_2.28.0-0ubunt2_amd64.deb I tried dpkg --configure -a and interestingly I get Package gnome-applets is not installed. When I try to use apt-get to install it, that same pesky problem pops up error processing /var/cache/apt/archives/gnome-applets_2.28.0-0ubunt2_amd64.deb (--unpack) subprocess new post-removal script returned error exist status 245 sub process /usr/bin/dpkg returned an error code(1) This file has been popping up with regards to a lot of the solutions suggested I see. Any ideas?

• Cannot open TUN/TAP dev /dev/as0t0: No such file or directory (errno=2)

  - by Mark

  I just attempted to install OpenVPN Access Server on my Debian VPS that uses OpenVZ. It installed fine, however when I try to start it from the administration panel, I get these errors: process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t0: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t1: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t2: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t3: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t4: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t5: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t6: No such file or directory (errno=2)'] service failed to start or returned error status process started and then immediately exited: ['Sat Sep 22 19:14:33 2012 Cannot open TUN/TAP dev /dev/as0t7: No such file or directory (errno=2)'] service failed to start or returned error status Is there a solution for this?

• Connection speed drops from 1 Gbps to 10 Mbps (Vista 64)

  - by Kevin Hakanson

  I recently got a Windows Home Server (HP MediaSmart Server EX490) setup so I could do backups and other things. However, I am having trouble on my Vista 64 PC. The backup will be making great progress, then it will just slow down. At one point, I noticed the lights on my Netgear GS105 indicated it was not using a 1000 Mbps connection, but a 10 Mbps one. I checked the Status of Local Area Connection (Intel(R) 82567V-2 Gigabit Network Connection) and that also showed the same slow speed. This has happened several times in the last couple days. When I disabled the network device, and then enabled it, it established the 1 Gpbs connection again. However, some of the times the Sent Bytes Activity on the Status windows indicate that the data flow is still slow (100 to 1000 bytes every couple seconds). Obviously, at this rate I could backup faster to floppy disk. :) My question is how to diagnose and fix this problem. When I look at the Administrative Events, I do a Errors: Bonjour Service 456: ERROR: read_msg errno 10054 (An existing connection was forcibly closed by the remote host.) And a Warning: e1yexpress Intel(R) 82567V-2 Gigabit Network Connection Link has been disconnected. I am suspicious there is some power saving mode. I found a post suggesting System Idle Power Saver(SIPS) may be the issue. I am going to try that, but looking for other suggestions or diagnostic advice. I have several new items in this configuration: server, client software, switch and cat6 cables.

• Can I change the file system on the OS partition on Server 2008 R2?

  - by KCotreau

  I have a client using R1Soft Continuous Data Protection backup, and two of the Server 2008 R2 boxes were erroring out with these errors: Unable to obtain NTFS volume data for device '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}': Incorrect function. Unable to discover information for filesytem volume '\\?\Volume{f612849e-7125-11e0-8772-806e6f6e6963}'; Unable to obtain NTFS volume So I backed up all the registry entries with this, {f612849e-7125-11e0-8772-806e6f6e6963}, in it, and deleted them based on some VERY sparse info from R1Soft. I then decided to restore them before I rebooted, and do a system state backup first using MS backup, and even it errored out saying that there were FAT32 partitions. This was a major clue as the only two computers with problems had these FAT32 partitions. I figured if MS backup can't backup something, any other program is likely to have problems. Also, now that I realized the servers had FAT32 partitions on them, the error referencing NTFS takes on more weight. The partitions on both servers have the label "OS", but on one of the computers, it is given a letter, but on the other not. So I am thinking if I just convert the file systems from FAT32 to NTFS, it may solve the backup problem. So the question is this: Can I just convert those partitions, and does anyone have any concrete knowledge of any major downsides, like the servers not coming back up (of course, I would do one at a time)? My thinking is that the answer is probably at least 95% no, but they are production servers, so I wanted to get some second opinions.

• Indefinite hang when restoring SQL 2005 database on a SQL 2008 server in EC2

  - by erinloy

  I'm trying to restore a 25 GB database backup taken from a Windows 2003/SQL 2005 machine to a Windows 2008/SQL 2008 machine in the Amazon EC2 cloud, using a .bak file and the SQL Management Studio. SQL Management Studio reports the restore reaches 100% complete, and then just hangs indefinitely (24+ hours) using a lot of CPU, until I restart the SQL Server service. Upon restart, SQL again uses a lot of CPU activity for what seems to be an indefinite amount of time, but the DB never comes online. Here are some details: - I have created two EBS volumes, one for DATA and one for LOGS, and I have set the default directories in SQL Server to the \DATA and \LOG directory on these respective volumes. (I wonder if the issue could be related to this, but the DB is too big to restore on the root drive.) - I have given the SQL Server user group full access to these directories. - The server can create a new empty test DB in these directories just fine, and can backup and restore the test DB. - I have tried both restoring of a .bak file and attaching directly to copies of the original .mdf/.ldf files, and the result is the same in both cases. - Both the .bak restore and the .mdf/.ldf attach occur from/to the EBS volumes. - I've also tried the above via SQL script, and "WITH RECOVERY", with no difference in the result, just less UI. - The backup contains two full text indexes. - I have to use "WITH MOVE" for most of the files in the backup. - There's nothing wrong with the backup or .mdf/.ldf files, as this works just fine on a Windows 2003/SQL 2005 machine in the Amazon EC2, but not Windows 2008/SQL 2008. - The DB is NOT marked as "Restoring" in the SQL Management Studio - it is just listed as a normal database, but throws errors when I try to do anything with it (expand the object browser tree, view properties, etc.) Any ideas?

• Issues with doing a P2V on Exchange 2007

  - by PokermUNKEE

  I shutdown all Exchange services on the physical box and did a convert. Everything converted fine. Server booted up no issues and I could receive email from the outside world with no issues. But I am unable to send emails internally or externally. They just sit in the Outbox. I also disabled the DHCPClient service as I didn't want the server to get an IP address from DHCP when it first came online. It came online with no IP, then I used console to assign the correct static IP address (same one on the physical server) and rebooted. I ran the Exchange Troubleshooting Agent and it gave me the following errors: The value for the '\MSExchangeIS Mailbox\Messages Queued For Submission' counter on server exchange is greater than zero (average value is 8.8) and it appears that 'MSExchangeMailSubmission' is failing to submit messages to at least one computer with the Hub Transport server role installed over the last minute. Found 1 computers with the Hub Transport server role installed in the same Active Directory site as server exchange using local Active Directory site GUID 'ce8a4367-1bf6-4825-9cac-c4e2b115c450'. Check Local Active Directory Site Hub Transport Server Role Health (Mailflow_CheckLocalBhHealth1.1.1.1.1.1.1.1) I have one Exchange server with all the roles on it. Has anyone see this before when doing a convert? Please help :(

• Upgrading Ubuntu to 9.04 breaks ATI video card driver, VESA and ati/radeon drivers

  - by Neil

  I upgraded my Ubuntu 8.10 to 9.04, and it not only broke the ATI proprietary fglrx driver, but also the ability to use the VESA or open-source ati or radeon drivers. I have an ATI RV610 which is an ATI Radeon HD 2400 XT. I have Linux Kernel 2.6.27-14-generic and 2.6.28-13-generic. With fglrx, vesa, ati and radeon, the Xserver hangs the machine as soon as it starts by invoking X or startx, which is seen by observing that caps lock doesn't work. There's nothing useful in /var/log/Xorg.0.log, no errors at all. This is with either kernel. When I download a new proprietary driver from ATI, I install it successfully on kernel 2.6.27, and it doesn't hang when X starts up, but it just shows a blank screen and does nothing. I also can't CTRL+ALT+Backspace out of X at this point. In all the years I've used ATI's Linux drivers, this has happened almost every time I've upgraded my kernel, but it's been fixable with much effort. This time I'm really stuck. Does anyone know how to fix these problems?

• Unable to execute gs program: No such file or directory

  - by Imran

  I've setup CUPS + Avahi on my NAS box in order to enable AirPrint with my existing network printer. Printing a test page via CUPS and printing us lp works fine, and I am able to see my printer on the printer list on my iOS device. However when sending a print job from my iOS device the printer status is set to paused and doesnt print anything. When checking the error_logs I have found this line which I believe is causing the error.

• mod_perl loses STDOUT in middle of request

  - by puzzled72

  Hi, I have been having this weird issue where mod_perl seems to lose STDOUT in the middle of the request. So far I have eliminated everything I could think of. You might have seen this bug related to the following errors in error_log : Apache2 IO flush: (103) Apache2::RequestIO::read: (104) Software caused connection abort They are all the same error. It happens when the perl script running under mod_perl loses STDOUT when trying to print the result back to apache. I only notice this error on my servers running the following: (centos5.4) Perl 5.8.8-27 mod_perl 2.0.4-6 httpd 2.2.3-31 kernel-2.6.18-164.15.1 It's not the code This code has been working for months It's not network related The browser gets the error response from apache. It's not time related I get the error 15 or so seconds after I restart httpd It's not idle httpd related I have tried reducing the min/max SpareServers to 1 It's not load related I get the error even if there are only 10 sessions on httpd It's not related to the "fd < PERLIO_MAX_REFCOUNTABLE_FD" perl 5.8.8 bug I recompiled perl-5.8.8 with the patch mentioned here : https://bugzilla.redhat.com/show_bug.cgi?id=559832, same error. It appeared sometime between December 2009 and February 2010 sorry I cannot be more specific Anyone has any idea ? Anything that I have not tested ? Really Puzzled!

• Windows 7 Sysprep Default User

  - by Demonwolf

  I seem to be having a problem with implementing my sysprep. I have been playing with Windows 7, WAIK, Server 2008 R2 and various other things. I managed to create a WIM with everything I need installed and I have worked out the autounattend.xml. I now have a Windows 7 64-bit complete unattended install from a USB device. It has all my programs, setting and everything done except one thing - the default profile set up 100% correctly. I have created a mostly set up default profile. I booted into audit mode, customized the Administrator account (mostly anyway) and then used sysprep with an unattend.xml file containing the copyprofile=true command. The file was set up with the WSIM and does not contain any extra info. This all works wonderfully. I recreated the WIM and all was good. I then decided to move the default location of the visible stuff in the user profile (Documents, Music, Pictures etc.) without changing the location of Appdata or other hidden folders. This is where things went a little... wrong. I went to the user folder (generally has the User name) with all the other folders in it. I right clicked on My Documents, found the location tab and changed it to M:\Documents. Now if I run sysprep /generalize /oobe /reboot /unattend:unattend.xml it starts the generalise... then spits out a fatal error and goes no further. The setuperr.log contains the following errors: 2011-08-18 23:21:43, Error [0x0f0043] SYSPRP WinMain:The sysprep dialog box returned FALSE 2011-08-18 23:31:57, Error [0x0f0082] SYSPRP LaunchDll:Failure occurred while executing 'C:\Windows\System32\slc.dll,SLReArmWindows', returned error code -1073425657 2011-08-18 23:31:57, Error [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = -1073425657 2011-08-18 23:31:57, Error [0x0f00a8] SYSPRP WinMain:Hit failure while processing sysprep generalize internal providers; hr = 0xc004d307 Does anyone have any ideas how I can redirect My Documents and other items in a user file to a second drive in the default profile so it affects each person logging in?

• Gitlab and Nginx not loading gitlab

  - by paperids

  I have just installed gitlab and nginx on Ubuntu LTS 12.04 using this guide: http://blog.compunet.co.za/gitlab-installation-on-ubuntu-server-12-04/ I installed this on another server last night and had absolutely no problems with it (sort of a test run to see how long it would take to get going). I am not getting any errors when restarting gitlab or nginx with /etc/init.d and my error logs are empty. The only thing I know of to go on is the vhost config: upstream gitlab { server unix:/home/gitlab/gitlab/tmp/sockets/gitlab.sock$ } server { listen localhost:80; server_name gitlab.bluringdev.com; root /home/gitlab/gitlab/public; # individual nginx logs for this gitlab vhost access_log /var/log/nginx/gitlab_access.log; error_log /var/log/nginx/gitlab_error.log; location / { # serve static files from defined root folder;. # @gitlab is a named location for the upstream fallback$ try_files $uri $uri/index.html $uri.html @gitlab; } # if a file, which is not found in the root folder is r$ # then the proxy pass the request to the upsteam (gitla$ location @gitlab { proxy_redirect off; # you need to change this to "https", if you set "ssl" $ proxy_set_header X-FORWARDED_PROTO http; proxy_set_header Host gitlab.bluringdev.com:80; proxy_set_header X-Real-IP $remote_addr; proxy_pass http://gitlab; } } If there's any other information that would be helpful, just let me know and I'll get it up asap.

• "Could not claim interface on camera: -6" when trying to connect usb camera (Kinect)

  - by rzetterberg

  I have installed the freenect library from openkinect.org. With that library there is a demo application which you can run from the terminal to test out the Kinect. However when I run this command I get the following output: richard@behemoth:~$ sudo freenect-glview Kinect camera test Number of devices found: 1 Could not claim interface on camera: -6 Could not open device This particular error is thrown by the library libusb by the function libusb_claim_interface and the error -6 corresponds to the LIBUSB_ERROR_BUSY. So my guess is that it has something to do with mounting the usb, rather than specifically the freenect library or the Kinect itself. So my question is how can I find out what resource is using this interface and how can I free it so that I can access it? Edit: What I have tried so far (just to be sure): Rebooted Plugged-out, plugged-in Tried different usb ports Restarted udev Additional information that might be useful: /etc/fstab: # /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda1 during installation UUID=1c73f217-ac8d-451b-8390-7a680628a856 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda5 during installation UUID=bb49bd29-07ec-45a0-bbab-46fb8362b06b none swap sw 0 0 sudo uname -r: Linux behemoth 3.0.0-14-generic-pae #23-Ubuntu SMP Mon Nov 21 22:07:10 UTC 2011 i686 i686 i386 GNU/Linux cat /etc/lsb-release DISTRIB_ID=Ubuntu DISTRIB_RELEASE=11.10 DISTRIB_CODENAME=oneiric DISTRIB_DESCRIPTION="Ubuntu 11.10"

• apache2 VirtualHost in Mac OS X home directory

  - by aaron

  I am running Macports apache2 on Mac OS X 10.5. Whenever I configure a virtual host in the default folder, it works, however when I configure the virtual host in my home directory I get a "403 Forbidden" error. How do I configure a vhost in my home directory? Here is the configuration that yields "403 Forbidden" when I access "devel.mysite.com": /opt/local/apache2/conf/extra/httpd-vhosts.conf: DocumentRoot "/opt/local/apache2/htdocs" ServerName * #CustomLog "" common <VirtualHost *:80> #DocumentRoot "/opt/local/apache2/htdocs/mysite" DocumentRoot "/Users/myuser/Sites/mysite" ServerName devel.mysite.com </VirtualHost> The error message in /opt/local/apache2/logs/devel.mysite.com-error_log: [Sat Apr 17 19:54:49 2010] [error] [client 127.0.0.1] client denied by server configuration: /Users/myuser/Sites/mysite/ When I uncomment the line to make DocumentRoot in /opt/local/apache2/htdocs/mysite, it works: DocumentRoot "/opt/local/apache2/htdocs" ServerName * #CustomLog "" common <VirtualHost *:80> DocumentRoot "/opt/local/apache2/htdocs/mysite" #DocumentRoot "/Users/myuser/Sites" ServerName devel.mysite.com </VirtualHost> I get no errors or warnings when I start apache, and the only thing that is logged on startup is this (in /opt/local/apache/logs/error_log): [Sat Apr 17 19:56:29 2010] [notice] Digest: generating secret for digest authentication ...

• How to run multiple instances of Tor?

  - by Ed

  I'm trying to set up a special proxy server (running Windows). It will have several instances of Privoxy and Tor running and my app will choose which Privoxy instance to send HTTP requests to depending on the load. Privoxy will then forward them to Tor. I'm using srvany.exe to create the services. At the moment I'm running 3 Privoxy and 3 Tor services (I copied the binaries to different folders). Each Privoxy service is listening to its own port (8118, 8119, 8120). I can see them listening in a port scanner. This is the application path (for srvany in registry) for the 1st service: C:\Anonymiser\Privoxy 01\privoxy.exe --service I've also configured the Tor services to listen to different ports (9050, 9052, 9054). This is the application path for the 1st service: C:\Anonymiser\Tor 01\tor.exe -f "C:\Anonymiser\Tor 01\torrc" The problem is, when I start the Tor services, only the first service I start is listening to its port. The others aren't listening. They listen if I run them separately. Any ideas what could be wrong? How can I make all 3 services listen on their assigned ports? This is one of my Privoxy configs: confdir . logdir . logfile privoxy.log debug 1 # show each GET/POST/CONNECT request debug 4096 # Startup banner and warnings debug 8192 # Errors - we highly recommended enabling this listen-address localhost:8118 toggle 0 enable-remote-toggle 0 enable-remote-http-toggle 0 enable-edit-actions 1 buffer-limit 4096 forwarded-connect-retries 0 forward-socks4a / localhost:9050 . This is one of my Tor configs: ControlPort 9051 Log notice stdout SocksListenAddress localhost SocksPort 9050 EDIT: Found a workaround. The Tor binary wants a lock on a file in the AppData folder. Because all of them want a lock on the same file, only the first one I start will be working. The workaround is to run each Tor instance under a different account. Not the best solution, but it works.

• Arch Linux drops me on my school network.

  - by Kravlin

  I'm running a Lenovo X61 which i carry around my college for getting on the internet at various points in the day. The network has always been finicky but recently it's gotten worse. I'll connect using iwconfig, get an ip from dhcpcd and log in using vpnc to their system. Sometimes I'll stay connected for hours but most of the time within 30 seconds my network traffic will drop to zero and i'll be unable to do anything. My computer still belives it's connected, however to try again i need to put my wireless interface down, put it back up and try again. It's gotten so bad that i've got a window on my computer pinging yahoo or google constantly in order to know if i'm still able to get online. I know other people who have used Arch Linux that don't have the same problems as well as people who use Ubuntu who haven't had any problems either. It seems like my computer is a special case. Does anyone have any suggestions on how to fix it? dmesg doesn't show anything out of the ordinary going on and i don't know where else to look for errors or other things to try.

• FFMPEG Install on EC2 - Amazon Linux

  - by Oliver Holmberg

  Hello Serverfault friends, I am about two days into attempting to install FFMPEG with dependencies on an AWS EC2 instance running the Amazon Linux AMI. I've installed FFMPEG on Ubuntu and Fedora systems with no problems in the past, and have read reportedly successful instructions on installing on Red Hat/Fedora. I have followed a number of tutorials and forum articles to do so, but have had no luck yet. As far as I can tell, the main problems are as followed: The amazon linux (Most similar to red-hat/centos) yum repositories don't have ffmpeg available. I have found instructions to update the repositories to include the required packages, but adding these repositories cause yum to fail in updating packages. (Also, I've read some cautionary tales about adding redhat/centos repositories to amazon linux that lead me to believe it may be a bad idea) (https://forums.aws.amazon.com/thread.jspa?messageID=229166) I have tried a more complicated method of downloading the source tarball, compiling, and installing, but this always fails due to missing dependencies and other errors. On to my question: Has anyone successfully installed FFMPEG on Amazon Linux? Is there a fundamental incompatibility? If anyone could share specific instructions on installing ffmpeg on amazon linux I would be greatly appreciative. Any other insights/experiences would also be appreciated. Thanks in advance, Oliver

• Finding cause of TCP retransmission within a LAN

  - by Surreal

  Hello denizens of Server Fault I have an irritating problem with a LAN of about 100 computers, 2 Windows domain servers, and 12 VoIP phones. Since their installation around a year ago, every week or so, we notice a VoIP phone resetting itself - occasionally in the middle of a call. Simultaneously there are often signs of temporary loss of connection on computers: freezes in explorer while accessing network shares, errors in our administration software due to loss of connection to the database server. I have been doing some Wireshark monitoring on the connection between the VoIP PBX and the rest of the network. Wireshark picks up a clump of retransmitted TCP packets at the times when we record phone restarts. The Wireshark log shows about 2 clusters of retransmissions a day ranging from 5 packets to hundreds. Those in each cluster are mainly between the PBX and some set of the VoIP phones, but not always the same set. Often retransmissions at the same time are to phones connected to the same switch, but sometimes retransmissions occur together to phones at opposite ends of the network. There are usually some coincident retransmissions in passing TCP traffic, for example between client machines and the file servers. The spikes in retransmissions and phone resets do not correlate well with when the network is heavily loaded. They seem to occur slightly more during the day, but most in the evening, when traffic should be decreasing. They occur reasonably often late at night when most computers are turned off and traffic should be lowest. Do you have any ideas that might help diagnose the cause of problems like this? One thing I have not yet tried, but should have, is updating the firmware of all the switches.

• how to import mesh animation from cinema4d into blender ?

  - by George Profenza

  I need to import a mesh animation from Cinema4D into Blender. I tried to do that using Collada.The Collada 1.3 importer doesn't seem to do anything, the Collada 1.4 importer seems to work, but the animation didn't get imported into Blender. After reading this post, I tried modifying the animation nodes in the collada files, as explained in the post: <library animation> <animation> <animation> data <animation> <animation> data <animation> <animation> <library animation> to this: <library animation> <animation> data <animation> <animation> data <animation> <library animation> , but that doesn't work for me. I get an errors when the file is parsed. Any hints on how to import a mesh animation from Cinema4D into Blender ?

• Windows Server 2008 Services won't start after patch

  - by Antitribu

  After installing the run of the mill patches today on a Windows Server 2008 (Running as an AD controller and Exchange 2007 Server) the machine came back up with "configuring updates stage 3 of 3 0% complete". The machine had been kept reasonably up to date so this likely was caused by a very recent patch. At the leaste the following patches were installed: KB973037 KB969947 KB973565 Restarting the server into safe mode and then subsequently rebooting (with no changes made) allowed the computer to restart and I can now log in normally. However none of the critical services start; including but not limited to Exchange, DNS and Terminal Services (Obviously if DNS doesn't start other things will break). I am unable to run Internet Explorer but Chrome will work. There are no meaningful errors in the event logs as to why services won't start. Under KDC I have The Key Distribution Center (KDC) cannot find a suitable certificate to use for smart card logons, or the KDC certificate could not be verified. Smart card logon may not function correctly if this problem is not resolved. To correct this problem, either verify the existing KDC certificate using certutil.exe or enroll for a new KDC certificate. This is going to be an evil one to debug and I'm kinda hoping someone has encountered it and knows the answer off hand. Thanks all.

• How to construct SELinux rules for a Glassfish server

  - by tronda

  I'm running Glassfish 3.1 on a CentOS 6 solution and by default SELinux is enabled. I have installed Sun's JDK version 1.6.0_29 on the server and extracted the Glassfish 3.1.1 to /opt/glassfish-3.1.1 with a link /opt/glassfish pointing to the latest Glassfish version. I've also created a system user named glassfish with a home directory /home/glassfish. When running with SELinux enabled I get all sorts of errors. For instance I'm not able to create the domain. I kind of like the concept of SELinux, and would like to be able to have SELinux enabled. I have the following requirements for the Glassfish server: Listening to port 8080 and 8081 Other ports 7676: JMS 8686: JMX monitoring, 4848: Admin console Forwarding from apache to Glassfish through mod_jk and port 8009 Starting OpenMQ as an separate process which listens to 7676 and it's JMX monitoring port 7776 Able to read and write files at a specified area (different from home directory) Able to use /tmp/ for temporary files I am aware of the audit2allow tool when running in permissive mode, but I struggle with understanding the rules that is generated from this tool, and thought that setting up these rule manually the first time would help me understand the SELinux rules better than the simplistic examples that I've seen so far. Can someone with SELinux experience help me form these SELinux rules with comments describing each part of the rules?
