• Windows XP, Preference menu's hidden for many programs

  - by Jestep

  I don't know when this started happening, but it has been several months since I first noticed it. Basically, when I go to a preferences menu of some programs, the preferences window is completely hidden, but the program see's it as being open. This prevents me from interacting with the preferences and the actual program. So far I've noticed it on Adobe Illustrator and Netbeans. Illustrator when I select edit - Preferences - An Option. On Netbeans it happens when I right click on a site and select properties. Here's a link to a screen shot after I click on the preferences menu (I don't have enough points to post an image yet): http://www.jestep.com/images/screen-2.jpg. Note that the main workspace is grayed out. I have to hit Escape to close the hidden preferences window. I've tried unstinstalling, completely wiping the registry of any trace of the program and reinstalling. Thought it may have been a multi-monitor issue when I switched from 2 monitors down to 1, but menu's were not on other monitor when I plugged one back in. I've reset workspaces, windows display, windows performance settings, changed resolution, safe mode, everything I can think of. I cannot figure out what would cause the same problem on completely unrelated software, and I cannot reset it by reinstalling. Any help would be greatly appreciated.

• With Ubuntu 9.10, my DVD keeps spinning up

  - by Ken

  I have Ubuntu 9.10 on my Intel Mac Mini. When there's a DVD in the drive, and even if there's no program open at all (just looking at the desktop), every minute or so the disc spins up with a loud whirring noise, and I can hear it cranking the motor to seek across the disc. How do I find out what's causing this? And how can I make it stop? Thanks! EDIT: I straced nautilus, and saw nothing it's doing directly, even when the disc spins up. It does poll inotify regularly, but I don't know how to trace what it's watching, or if that's even how it receives disc-inserted notifications. It doesn't call inotify_add_watch when I insert a disc or mount it (or eject or umount), but it could be watching all of /dev already or something like that. Of course, a DVD is mounted read-only, so whether it's inotify or something else, it should never need to poll anything on that. And if it is inotify, it's happening in the kernel, and the kernel should really never need to poll a device it's mounted to check for notifications.

• fast way to find network user computer on domain hogging all wan bandwidth

  - by dasko

  i have a network of about 40 domain users and i have huge latency wan issues, like 1400ms for google.com pings. I have noticed that the problem goes away after everyone goes home for the day. I would like to know if i should use something like a hub with wireshark on the router or modem to see if there are any irregular activity. I am open to suggestions but i need to isolate which user has the bug. I am assuming it is either downloads or someone spamming out heavily and not knowing. It would be best to trace to ip number so i can just look into dns and find the pc hostname with the problem? This is the first client i have this problem with so never really needed to address it before but not suprised as users don't actually listen to any best practices that we have suggested. Please help, thanks. just to update, pc's to routers and other computers have ping latency of 1ms so it is right after i hit the wan, using tracert to a web site (random), that i get the massive delay in the responses. As well this is a dsl line with 5mb down and 650kb up (maybe upload saturation?) thanks.

• Perl EPIC Not recognising installed CPAN modules

  - by Recc

  Eclipse on a mac, was working fine adding new modules until I Installed Text::CSV_XS which Eclips doesn't recognise as added to @INC For instance use strict; use SOAP::Transport::HTTP; SOAP::Transport::HTTP::CGI->dispatch_to('C2FService')->handle; BEGIN { package C2FService; use vars qw(@ISA); @ISA = qw(Exporter SOAP::Server::Parameters); use SOAP::Lite; sub c2f { my $self = shift; my $envelope = pop; my $temp = $envelope->dataof("//c2f/temperature"); return SOAP::Data->name( 'convertedTemp' => ( ( ( 9 / 5 ) * ( $temp->value ) ) + 32 ) ); } } use SOAP::Transport::HTTP; is marked as error if I comment it out use SOAP::Lite; is in turn marked as an error, not found etc the usual if a module is not installed. Both are installed with CPAN and $ perl -c soap-test.pl post-code-check.pl syntax OK Perl is fine CPAN tests are all pass, the code works, only EPIC lags behind. $ pwd && ls /opt/local/lib/perl5/site_perl/5.12.4/SOAP Client.pod Lite Server.pod Constants.pm Lite.pm Test.pm Data.pod Packager.pm Trace.pod Deserializer.pod SOM.pod Transport Fault.pod Schema.pod Transport.pod Header.pod Serializer.pod Utils.pod And if I have use errors in the start of my files the rest of the source is not error checked..

• finding the user - without knowing the innards of IIS

  - by LosManos

  Place of crime is WinSrv2008 with IIS7. My IIS apppool user is trying to create a folder but fails. How do I find out which User it is? Let's say I don't know much about IIS7 and Aspnet but need to trace whatever is happening through tools. So I fire up Sysinternals/ProcessMonitor to find out what is happening. I find Access denied on a folder just as I suspected. But which user? I add the User column to the output or ProcessMonitor and it says IIS Apppool\Defaultapppool in capitals. Well... that isn't a user is it? If I go to IIS and its Apppools and Advanced settings and Process model and Identity I can see clues about which user it is but that is only because I know IIS. What if it had been Apache or LightHttpd or whatever? How do I see the user to give the appropriate rights to?

• JBoss 5 on AIX 5.3

  - by jess

  I am a very newbie for AIX and system monitoring. Actually our application currently run production on jboss 5.1 in AIX 5.3. Please check below configuration & system settings. AIX system configuration OS Level 5.3.9.0 (oslevel -g) Physical Memory size 24GB (svmon -G) Page space 4GB (lsps -s) processors 3 cores, Processor Type: PowerPC_POWER6, Processor Clock Speed: 4704 MHz (prtconf | grep Processor) Java version JRE 1.6.0 IBM AIX build pap6460sr10fp1-20120321_01 (SR10 FP1) (java -fullversion) JBoss configuration JBoss 5.1/JBoss ESB 4.11 Hornetq messaging with consumer flow control java opts : -d64 -Xms2g -Xmx4g -XX:MaxPermSize=1024m Sometime we observe very strange behavior in the JBoss that freeze without any error logs. Also server log stop without any further trace. We also not able to get thread dump (kill -3) and its not generate at that point. (kill -3 xxxxx works in normal circumstances) Only option available for us was restart the jboss server and its seem all messages that were in queues during the freeze time process after restarting. We try tweak some of setting in JBoss hornetq, we though issue was there. Hornetq Stuck By Default. But we haven't any luck and also unable to isolate the issue in any point. We looking at tool like nmon for monitoring this but no clue is that good enough to do so. Please provide some point to investigate this issue. Thanks

• Identifying and Resolving Oracle ITL Deadlock

  - by Allan

  I have an Oracle DB package that is routinely causing what I believe is an ITL (Interested Transaction List) deadlock. The relevant portion of a trace file is below. Deadlock graph: ---------Blocker(s)-------- ---------Waiter(s)--------- Resource Name process session holds waits process session holds waits TM-0000cb52-00000000 22 131 S 23 143 SS TM-0000ceec-00000000 23 143 SX 32 138 SX SSX TM-0000cb52-00000000 30 138 SX 22 131 S session 131: DID 0001-0016-00000D1C session 143: DID 0001-0017-000055D5 session 143: DID 0001-0017-000055D5 session 138: DID 0001-001E-000067A0 session 138: DID 0001-001E-000067A0 session 131: DID 0001-0016-00000D1C Rows waited on: Session 143: no row Session 138: no row Session 131: no row There are no bit-map indexes on this table, so that's not the cause. As far as I can tell, the lack of "Rows waited on" plus the "S" in the Waiter waits column likely indicates that this is an ITL deadlock. Also, the table is written to quite often (roughly 8 insert or updates concurrently, as often as 240 times a minute), so and ITL deadlock seems like a strong possibility. I've increased the INITRANS parameter of the table and it's indexes to 100 and increased the PCT_FREE on the table from 10 to 20 (then rebuilt the indexes), but the deadlocks are still occurring. The deadlock seems to happen most often during an update, but that could just be a coincidence, as I've only traced it a couple of times. My questions are two-fold: 1) Is this actually an ITL deadlock? 2) If it is an ITL deadlock, what else can be done to avoid it? Cross-posted from Stack Overflow. Deadlocks are normally a programming problem, but ITL deadlocks relate directly to how Oracle writes to disk, so this may be an area where DBAs have more experience.

• Postfix Postscreen: how to use postscreen for smtp and smtps both

  - by petermolnar

  I'm trying to get postscreen work. I've followed the man page and it's already running correctly for smtp. But it I want to use it for smtps as well (adding the same line as smtp in master.cf but with smtps) i receive failure messages in syslog like: postfix/postscreen[8851]: fatal: btree:/var/lib/postfix/postscreen_cache: unable to get exclusive lock: Resource temporarily unavailable Some say that postscreen can only run once; that's ok.

• FastCGI and Apache 500 error intermittently

  - by benkorn1

  Hello, I have a FastCGI (mod_fastcgi)problem. It happens every once in a while, and does not casue a complete server meltdown, just 500 errors. Here are a couple things. First I am using APC so PHP is in control of it's own processes, not FastCGI. Also, I have the webroot set as: /var/www/html And the fcgi-bin inside: /var/www/html/fcgi-bin First off here is the apache error_log: [Fri Jan 07 10:22:39 2011] [error] [client 50.16.222.82] (4)Interrupted system call: FastCGI: comm with server "/var/www/html/fcgi-bin/php.fcgi" aborted: select() failed, referer: http://www.domain.com/ I also ran strace on the 'fcgi-pm' process. Here is a snip from the trace around the time it bombs out: 21725 gettimeofday({1294420603, 14360}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6503 38*", 16384) = 46 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 96595}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6154 23*C /var/www/html/fcgi-bin/php.fcgi - - 6483 28*", 16384) = 92 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 270744}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 5741 38*", 16384) = 46 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 311502}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6064 32*", 16384) = 46 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 365598}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6179 33*C /var/www/html/fcgi-bin/php.fcgi - - 5906 59*", 16384) = 92 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 454405}, NULL) = 0 I noticed that the 'select()' seems to stay the same regardless, however the read() changes its return from 46 to some other number while it is bombing out. Has anyone seen anything like this. Could this be some sort of file locking? Thanks, Ben

• How to troubleshoot Hyper-V VSS writer causing backup failure on Server 2008 R2

  - by Tim Anderson

  I have a Windows Server 2008 R2 machine running Hyper-V. Backups using Windows Server Backup fail with the error: The backup operation that started at '?2011?-?01?-?02T10:37:01.230000000Z' has failed because the Volume Shadow Copy Service operation to create a shadow copy of the volumes being backed up failed with following error code '2155348129'. Please review the event details for a solution, and then rerun the backup operation once the issue is resolved. I have traced this to a problem with the Hyper-V VSS writer. vssadmin list writers reports: Writer name: 'Microsoft Hyper-V VSS Writer' Writer Id: {66841cd4-6ded-4f4b-8f17-fd23f8ddc3de} Writer Instance Id: {fcf0dd79-d282-4465-88ae-7b6857e055c2} State: [8] Failed Last error: Inconsistent shadow copy However I can't get any further. A few relevant facts: I get the error even if all the VMs are shut down If I disable the Hyper-V VSS Writer by stopping the Hyper-V Management Service backup completes OK There are no errors in the Hyper-V-VMMS application log I tried to set tracing for VSS but can't get any output for some reason. I set the correct registry entries but no trace log is generated. Tim

• Messed up USB stick doesn't show in blkid

  - by Felix

  I was playing around with a USB stick (booting archlinux with qemu off of it and trying to perform an installation on the same stick at the same time -- brave, I know, but I was just messing around). Now, after failing to boot and install at the same time, it seems I have sort of messed up my stick. What I think happened is that I used cfdisk to wipe everything on it and create one big partition, but formatting it then failed, so now there's a big partition with no filesystem. Just to make it clear: I'm not worried for my stick, I know I can recover it at any point. What I find intriguing is that after plugging the stick into my computer (using Ubuntu), there's no (terminal) way to find out what block device (/dev/sdx) it has associated. The only way I could determine that was with GParted: But blkid shows the following: /dev/sda1: UUID="12F695CFF695B387" LABEL="System Reserved" TYPE="ntfs" /dev/sda2: UUID="A0BAA6EABAA6BC62" TYPE="ntfs" /dev/sdb1: UUID="546aec8b-9ad6-4571-b07a-adba63e25820" TYPE="ext4" /dev/sdb2: UUID="2a8b82d8-6c6e-4053-a446-bab970d93d7c" TYPE="swap" /dev/sdb3: UUID="7cbede7d-c930-4e59-9d1b-01f2d79bd092" TYPE="ext4" No trace of /dev/sdc. My question is: if I didn't have a graphical interface (to use GParted), how would I have known which block device is my stick?

• Massive SQL issue shutting down our site.

  - by Pselus

  Our website has started timing out like crazy today. All of our clients are finding it unusable. The only error we can seem to trace down as a potential problem is this: SQLAllocHandle on SQL_HANDLE_DBC failed Error ASP Description Error Category Microsoft OLE DB Provider for ODBC Drivers I have no idea what it means or how to go about fixing it. Anyone ever encountered this error before? Currently, you can log in to our site, but then once you go to do anything else, you find yourself logged out or nothing happens. We have a lot of Ajax going on so the "nothing happens" probably has to do with the Ajax pages not loading properly due to logouts and so nothing displays to the user. Like I said, I'm at a loss. Anyone have any advice on this error? EDIT I realize that this isn't necessarily a programming question, but we are a small startup company that just yesterday started talking about how we need to get a backup server running. Apparently we talked about it too late. We don't have a DBA, just 2 mid level programmers trying their hardest to keep our clients happy. So please, if you have any assistance give it but please don't close my question right now. EDIT 2 Turns out we had something on our server running called "ServerMask" that makes our IIS server look like Apache to the outside world. Shutting it down fixed our issue. Still no idea why it was messing up but it was the problem apparently. Thanks to everyone who tried to help.

• How to diagnose a hang when creating a new folder in explorer.exe

  - by Jack Ukleja

  I have been having some issues with explorer.exe hanging when I create a new folder. If I use Analyse Wait Chain in the Resource Monitor it says "One or more threads of explorer.exe are waiting to finish network I/O". When I look at the offending thread in Process Explorer it reveals nothing interesting: ntdll.dll!ZwWaitForMultipleObjects+0xa KERNELBASE.dll!GetCurrentThread+0x36 kernel32.dll!WaitForMultipleObjectsEx+0xb3 USER32.dll!PeekMessageW+0x1cd USER32.dll!MsgWaitForMultipleObjectsEx+0x2a USER32.dll!MsgWaitForMultipleObjects+0x20 SHELL32.dll!SHAppBarMessage+0x41e SHELL32.dll!DragAcceptFiles+0x2a3c SHELL32.dll!DragAcceptFiles+0x2a4f SHELL32.dll!Ordinal211+0x124 SHELL32.dll!SHChangeNotification_Unlock+0x12f4 USER32.dll!GetSystemMetrics+0x2b1 USER32.dll!IsDialogMessageW+0x19b USER32.dll!IsDialogMessageW+0x1e1 ntdll.dll!KiUserCallbackDispatcher+0x1f USER32.dll!PeekMessageW+0xba USER32.dll!PeekMessageW+0x89 SHELL32.dll!SHChangeNotification_Unlock+0xd9f SHELL32.dll!Ordinal885+0x1407 SHLWAPI.dll!SHRegGetUSValueW+0x306 kernel32.dll!BaseThreadInitThunk+0xd ntdll.dll!RtlUserThreadStart+0x21 While I was looking at the explorer.exe threads I did notice a fair few that talk about ETW (Event Tracing for Windows) so obviously explorer.exe uses tracing. So I decided to try and user TraceView.exe to try and listen in on the explorer.exe traces. The problem is TraceView requires some difficult-to-come-by stuff... either pdbs, or CTL files, and .TMF files. I tried using the explorer.pdb that comes with the Windows SDK but that did not work. I do not see explorer.exe in the "named providers". And I have no idea where to locate the ctl or .TMF files for explorer.exe. So the question is: Is there a way to view the ETW trace messages from explorer? Or shall I just not bother and go back to the age old technique of disabling every explorer extenion one-by-one in the hope its one of them. (Prefer the former as I like to get to the bottom of things!!)

• Some Can reach bidmail.com others can't.

  - by user69426

  On a windows 7 Professional machine in Chrome one of our Estimating assistants can't get to www.bidmail.com, however the other 3 can. On his machine I did nslookup then bidmail.com and it fails to find it. I then went to a machine that could reach bidmail and did nslookup. It can't find it. I was skeptical and thought maybe it was a cached page so I cleared the cache then went back to bidmail.com was able to get to the page, login, lookup a newly posted bid then download the file. Yet I can not look it up through nslookup and I can't ping it www.bidmail.com and I can't trace it. I remoted to our other warehouse which is set up as a workgroup and attempt to nslookup bidmail and that nslookup fail... and on that machine which has never been to bidmail before it was able to connect to the website! I am totally confused if I can't ping it and I can't use nslookup to get there how in the hell is Chrome getting to the page and how do I get this guy back on? Also while typing this I took a new laptop out of the box plugged it in with no updates and can get to bidmail! omg!

• Strange IIS hits originating from Trend Micro

  - by TesterTurnedDeveloper

  I'm trying to trace thru an error on a extranet site I maintain. I've had a look thru the logs, and I'm seeing hits originate from these IP addresses: 216.104.15.130 216.104.15.138 216.104.15.142 216.104.15.13 150.70.84.49 150.70.84.44 Network-tools.com gives 'TREND MICRO INCORPORATED' as the owner of all these IPs. The hits fail as they aren't sending any cookies (therefore aren't considered logged in). The hits are to pages containing URLs that only the logged in user would see, i.e. ImageEdit.aspx?ImageId=467424. I.e. the server isn't guessing these URLs, someone would have to log into the site to know these URLs exist. Theory: the Trend Antivirus client grabs URLs and sends them to the server for 'extra processing'? Googling around gives me this: http://www.forumpostersunion.com/showthread.php?p=51272 - where people are reporting comment spam from these addresses. The articles says their servers have been hacked (a few months ago, presumably fixed now?). A hacked server wouldn't explain how the URLs have been plucked off the user's PCs. Has anyone seen this before? Anything nefarious going on here?

• mod_rewrite REQUEST_FILENAME doesn't contain absolute path

  - by Paul Dixon

  I have a problem with a file test operation in a mod_rewrite RewriteCond entry which is testing whether %{REQUEST_FILENAME} exists. It seems that rather than %{REQUEST_FILENAME} being an absolute path, I'm getting a path which is rooted at the DocumentRoot instead. Configuration I have this inside a <VirtualHost> block in my apache 2.2.9 configuration: RewriteEngine on RewriteLog /tmp/rewrite.log RewriteLogLevel 5 #push virtually everything through our dispatcher script RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^/([^/]*)/?([^/]*) /dispatch.php?_c=$1&_m=$2 [qsa,L] Diagnostics attempted That rule is a common enough idiom for routing requests for non-existent files or directories through a script. Trouble is, it's firing even if a file does exist. If I remove the rule, I can request normal files just fine. But with the rule in place, these requests get directed to dispatch.php Rewrite log trace Here's what I see in the rewrite.log init rewrite engine with requested uri /test.txt applying pattern '^/([^/]*)/?([^/]*)' to uri '/test.txt' RewriteCond: input='/test.txt' pattern='!-f' => matched RewriteCond: input='/test.txt' pattern='!-d' => matched rewrite '/test.txt' -> '/dispatch.php?_c=test.txt&_m=' split uri=/dispatch.php?_c=test.txt&_m= -> uri=/dispatch.php, args=_c=test.txt&_m= local path result: /dispatch.php prefixed with document_root to /path/to/my/public_html/dispatch.php go-ahead with /path/to/my/public_html/dispatch.php [OK] So, it looks to me like the REQUEST_FILENAME is being presented as a path from the document root, rather than the file system root, which is presumably why the file test operator fails. Any pointers for resolving this gratefully received...

  We have two test web farms (IIS 7.5). The Florida web farm has two ARR servers and two content servers. The ARR servers have WFF and NLB installed. The ARR setup uses a shared config located on a file share. The content servers do not have WFF installed. There is one web farm, and it's managed on an ARR server. The Illinois web farm also has two ARR servers and two content servers. ARR servers have WFF and NLB installed, and they use a shared config located on a share. One of the content servers has WFF installed, which makes it the controller; it's also the primary content server. Apparently, Illinois isn't properly configured. From what we've pieced together from various IIS.net articles and this post (http://ruslany.net/2010/07/web-farm-framework-2-0-overview/), the controller should be one of the ARR servers (like our Florida setup). The thing is Florida's controller doesn't have a Primary server nor can you set one of the content servers as Primary. It doesn't have the management piece showing the Trace messages when you click the Servers node (from iis console, Server Farms/FLFarm/Servers http://ruslany.net/wp-content/uploads/2010/07/WebFarm8.png). That management piece does exist in the Illinois farm, but that's a bad configuration. What are we missing that our Florida configuration doesn't have the Primary and Secondary content servers, and the management piece? I have looked for IIS role differences, but there are none.

• FastCGI and Apache 500 error intermittently

  - by benkorn1

  I have a FastCGI (mod_fastcgi)problem. It happens every once in a while, and does not casue a complete server meltdown, just 500 errors. Here are a couple things. First I am using APC so PHP is in control of it's own processes, not FastCGI. Also, I have the webroot set as: /var/www/html And the fcgi-bin inside: /var/www/html/fcgi-bin First off here is the apache error_log: [Fri Jan 07 10:22:39 2011] [error] [client 50.16.222.82] (4)Interrupted system call: FastCGI: comm with server "/var/www/html/fcgi-bin/php.fcgi" aborted: select() failed, referer: http://www.domain.com/ I also ran strace on the 'fcgi-pm' process. Here is a snip from the trace around the time it bombs out: 21725 gettimeofday({1294420603, 14360}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6503 38*", 16384) = 46 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 96595}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6154 23*C /var/www/html/fcgi-bin/php.fcgi - - 6483 28*", 16384) = 92 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 270744}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 5741 38*", 16384) = 46 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 311502}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6064 32*", 16384) = 46 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 365598}, NULL) = 0 21725 read(14, "C /var/www/html/fcgi-bin/php.fcgi - - 6179 33*C /var/www/html/fcgi-bin/php.fcgi - - 5906 59*", 16384) = 92 21725 alarm(131) = 0 21725 select(15, [14], NULL, NULL, NULL) = 1 (in [14]) 21725 alarm(0) = 131 21725 gettimeofday({1294420603, 454405}, NULL) = 0 I noticed that the 'select()' seems to stay the same regardless, however the read() changes its return from 46 to some other number while it is bombing out. Has anyone seen anything like this. Could this be some sort of file locking? Thanks, Ben

• Team Foundation Server 2008 - TF220056 Error during installation

  - by David

  I'm attempting to install Team Foundation Server 2008 on a Windows Server 2003 instance that exists under Hyper-V. The SQL Server database itself is held on the root partition of the Hyper-V server and has the Reporting Services installed (so I've solved the TF220059 error already). After hitting "Next " after typing the name of the SQL Server I get this error: --------------------------- Microsoft Visual Studio 2008 Team Foundation Server Setup --------------------------- TF220056: An unrecoverable error occurred while trying to check the status of the Team Foundation database. Installation cannot continue. Check the install log for more details. --------------------------- OK --------------------------- The error log's stack trace makes it look like a bug in the TFS installer itself: [03/22/10,19:14:42] TFSUI: [2] tfsdb.exe: System.IO.IOException: The directory name is invalid.

• server and user directly connected no pinging...

  - by jtzero

  I have a server(fedora 12) with two nics on it, directly connected to say 192.168.1.0 and 192.168.2.0 the route table looks like this Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 192.168.1.1 255.255.255.0 U 0 0 0 eth0 192.168.2.0 * 255.255.255.0 U 0 0 0 eth1 eth0 = 192.168.1.15 eth1 = 192.168.2.1 and a directly connected user (Mythdora) on the 192.168.2.0 network with ip 192.168.2.2 and route table like so Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.2.0 * 255.255.255.0 U 0 0 0 eth0 the cable is a crossover and it works all three nics work -- connected my laptop to either end and assign it a valid 192.168.2.0 ip the pings will work. In fact if I disconnect the server side and plug the eth cable into the laptop and have thte box ping the laptop continually remove the eth cable and plug it back into the server both sides ping... unfortunately the box realizing it's connected to a different pc wipes its route table after say ten minutes or so. if I do a trace route from a box on the 1.0 network to the servers 192.168.2.1 interface never get a reply from it. as a note at one point I could ping the server from the 192.168.2.2 box but the server couldnt ping the 192.168.2.2 box.

• How to recover a Linksys WRT54GL router that has a blinking green power LED and no response from the

  - by Peter Mounce

  I was flashing the router with the Tomato firmware, but something went wrong; I'm not sure what. Now, the router responds to ping at 192.168.1.1 (my Mac's on a static IP 192.168.1.21), but the web-interface doesn't come up. I have read that this situation is recoverable in a [couple of places][2], but I haven't been having much success and so I wondered whether anyone could help. From my Mac (OSX 10.5) I have tried to tftp a new vanilla-Linksys firmware to the router and reboot; according to the trace, this sends it but the router behaves no differently after a reboot. I've read that if boot_wait is turned on, I'll have an easier time, but I haven't been able to find any instructions that tell me how I can tell whether I did this or not (I don't think I have, but I might have, when I tinkered the first time months ago - the router has worked since then, though). I have found a couple of references to [something called JTAG][3], which seems like some kind of [homebrew diagnostic cable thing][4], but that's a little beyond my ken. Happy to try it, with muppet-level instructions, though (I do software, not hardware!). So, I'm at a bit of a loss, really, and wondered whether anyone could provide me with the route (ha. ha.) out of this mess? Hm, I can't post all the links I wanted to until I have some more reputation.

• Robocopy silently missing files

  - by John Hunt

  I'm using Robocopy to sync data from our server's hard disk to an external disk as a backup. It's a pretty simple solution but pretty much the best/easiest one we could come up with - we use two external disks and rotate them offsite. Anyway, here's the script (with the comments taken out) that I'm using to do it. It works very well, it's quick and almost 100% complete - however it's acting pretty strange with a few files (note company name has been changed in paths to protect the innocent): @ECHO OFF set DATESTAMP=%DATE:~10,4%/%DATE:~4,2%/%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2% SET prefix="E:\backup_log-" SET source_dir="M:\Company Names Data\Working Folder\_ADMIN_BACKUP_FILES\COMPA AANY Business Folder_Backup_040407\COMPANY_sales order register\BACKUP CLIENT FOLDERS & CURRENT JOBS pre 270404\CLIENT SALES ORDER REGISTER" SET dest_dir="E:\dest" SET log_fname=%prefix%%date:~-4,4%%date:~-10,2%%date:~-7,2%.log SET what_to_copy=/COPY:DAT /MIR SET options=/R:0 /W:0 /LOG+:%log_fname% /NFL /NDL ROBOCOPY %source_dir% %dest_dir% %what_to_copy% %options% set DATESTAMP=%DATE:~10,4%/%DATE:~4,2%/%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2% cscript msg.vbs "Backup completed at %DATESTAMP% - Logs can be found on the E: drive." :END Normally the source would just be M:\Comapany name data\ but I altered the script a bit to test the problem. The following files in the source are not copied to the dest: Someclient\SONICP~1.DOC Someclient\SONICP~2.DOC Someclient\SONICP~3.DOC However, files in the same directory named: TIMESH~1.XLS TIMESH~2.XLS are copied. I'm able to open the files that aren't copied with no trouble at all, and they certainly weren't opened when I ran robocopy so it's not a locking issue. Robocopy is running as administrator so it's not a permissions issue. There's no trace these files were even attempted to be copied as there are no errors being output in the log or in my command prompt. Does anyone have any suggestions as to what this might be? Busted hard disk? Cheers, John.

• Regular Windows 7 BSOD with Shrew VPN client

  The Shrew VPN client appears to be a good alternative to the Cisco VPN Client on x64 Windows 7. However, since installing it I've seen fairly regular BSODs.

Superuser appears to have several recommendations for the Shrew VPN Client as an alternative to the Cisco VPN client on 64 bit machines, so I wondered if anyone here has seen this problem and possibly found a solution to the problem? I've decided to run the VPN client under Windows 7 compatibility mode for the moment (Vista SP2) with administrator privileges to see if it makes a difference. Oddly, the VPN doesn't necessarily need to be connected. I've noticed it when browsing using Google Chrome and Internet Explorer, usually when I open up a new tab. If it carries on I think I'll be forced to shell out the 120 EUR for the NCP Client instead.

• jdbc4 CommunicationsException

  - by letronje

  I have a machine running a java app talking to a mysql instance running on the same instance. the app uses jdbc4 drivers from mysql. I keep getting com.mysql.jdbc.exceptions.jdbc4.CommunicationsException at random times. Here is the whole message. Could not open JDBC Connection for transaction; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was25899 milliseconds ago.The last packet sent successfully to the server was 25899 milliseconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. For mysql, the value of global 'wait_timeout' and 'interactive_timeout' is set to 3600 seconds and 'connect_timeout' is set to 60 secs. the wait timeout value is much higher than the 26 secs(25899 msecs). mentioned in the exception trace. I use dbcp for connection pooling and here is spring bean config for the datasource. <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" > <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/db"/> <property name="username" value="xxx"/> <property name="password" value="xxx" /> <property name="poolPreparedStatements" value="false" /> <property name="maxActive" value="3" /> <property name="maxIdle" value="3" /> </bean> Any idea why this could be happening? Will using c3p0 solve the problem ?
