  • Apache2 - 500 internal server error

    - by Lucio Coire Galibone
    i'm running a VPS with Linux CentOs 6 with 4 GB of RAM, 10 GB of HD and 2 virtual CPU Intel(R) Xeon(R)CPU L5640 @ 2.27GHz. As my host says each virtual CPU must be at least 0.5 physical cpu. At certain times of the day, those with more traffic, trying accessing my php script i receive intermittently "500 internal server error". I activate logging to debug level from apache, and also the PHP logging with E_ALL, but I can't find reference to Error 500 in any logs(I checked the right logs!). I haven't got any .htaccess file in path script. The strange thing is that the error start at first php line in the script (the previous html displays correctly, but at the first php line the script send 500 error). The cpu load is always good (max 0.15 0.08 0.01) and RAM is close to 95% but it arrived to swap just 2 times in a month with 2-5 MB. Apache works with prefork with this values: <IfModule prefork.c> StartServers 8 MinSpareServers 5 MaxSpareServers 20 ServerLimit 280 MaxClients 280 MaxRequestsPerChild 4000 </IfModule> Everthing works correctly and I don't get any error in quiet times, but i start receive errors when traffic rises (6-9000 visits per hour). Can i solve the problem increasing resources? (i can upgrade RAM up to 16 GB). It can depend from reaching MaxClients (but apache must write it on log, right?)? If I upgrade RAM to 6 or 8 GB i have to calculate MaxClients value with this? MaxClients = Total RAM dedicated to the web server / Max child process size Max child process size is around 20M. How else can the problem be? Thanks in advance

  • I get a Segmentation fault when doing apt-get util-linux

  • PHP output buffer settings ignored by server

    - by Ecom Evolution
    I have been trying to flush the output of certain scripts to the browser on demand, but they do not work on our production server. For instance, I tried running the "Phoca Changing Collation tool" (find it on Google) and I don't see any output until the script finishes executing. I've tried immediately flushing the buffer on other scripts that work fine on any server but this one using the following code: echo "something"; ob_flush(); flush(); Setting "ob_implicit_flush(1);" doesn't help either. The server is Apache 2.2.21 with PHP 5.2.17 running on Linux. You can see our php.ini file here if that will help: http://www.smallfiles.org/download/1123/php.ini.html This isn't the only problem we are having with the server ignoring in-script directives. The server also ignores timeout coding such as: ini_set('max_execution_time', 900*60); AND set_time_limit(86400); Script always times out at the php.ini default. Doesn't seem to matter if script is executed in IE or Firefox. Tried "ini_set('zlib.output_compression_level', 'Off');" and checked that it is "Off" in the php.ini file. The code "apache_setenv('no-gzip', 1);" causes a fatal error so tried uploading a .htaccess file with the "mod_gzip_on No" directive. Neither helps. Tried running Apache as fcgi and suphp, but same results. Server is NOT in safe mode. Pullin ma hair out!

  • Excessive CPU Utilization for Bind 9.8.1 `named` processes

  • Ubuntu 10.04 LTS - Dual monitor works only sometimes (ATI multi-desktop)

    - by Beres Botond
    I've been using my laptop with an external LCD monitor attached to it at work (Philips 201E). And at home with a different external monitor (Samsung 2032BW). I have an ATI graphics card (HD3450), with Ati Catalyst drivers enabled and I'm using the Single display desktop (Multi-Desktop) seeting. At work I have the external monitor on the left and laptop on the right, while at home the other way around. So when I switch between the two setups, I just needed to go to Ati Catalyst Control Center, change the order of the displays, change the resolution (Home - 1680x1050, Work - 1440x900), reboot and it was all fine. But since a while it doesn't work properly anymore: At home it still works fine. At work it doesn't work. Sometimes it works for some reason, after a few resolution/setting changes in ACCC and reboots... it's very strange and annoying. With the home monitor I can see the whole bootup process on both monitors (laptop + LCD) and it always just works fine. With the work monitor on the external LCD monitor I just see "No video input" until I get to the login screen, then it shows up there as well. But after login it will either: Flicker a few times, but then work OK. Or (more often) Flicker once and then go back to "No video input" again. I usually end up rebooting a few times until it works. Does anyone have any idea for fixing it?

  • Synchronization of volume snapshots when doing whole system backups

    - by intuited
    Is there a way to guarantee consistency across volumes when doing backups from LVM snapshots? Consider this scenario: Some system upgrade is in progress. It will write some files to the /usr volume, and once completed, will record success in the /var volume. As the upgrade is just about complete, I run a backup script that creates snapshots of the /usr and /var volumes, along with the rest of the system's volumes, and proceeds to create backups from those snapshots. Just before the upgrade's last write/flush on the /usr volume completes, the backup script takes its snapshot of /usr. That write completes, and the upgrade operation's success is quickly recorded in the nebulous depths of /var. The backup script takes a snapshot of /var. The backup script creates backups from the snapshots it has, er, snapshotted. So the result of all of this tomfoolery is that the resulting /usr backup contains a file which is missing a few bits, and the /var backup contains metadata indicating that that file is complete and approved for use. Without delving into the details of which operating systems' system upgrade systems would be unfazed by such trifles, is there a way to avoid such problems? At the least this seems like it could cause some application to fail unexpectedly after restoration of such a backup.

  • IIS7 - Virtual Directories' Parent Paths behaving differently than previous versions

    - by MisterZimbu
    I'm doing a migration of a web server running on IIS 5 to IIS 7. I'm noticing that the virtual directories are behaving differently between the two. I have a site located at c:\inetpub\SiteName. This site contains a virtual directory "bob" that points at c:\virtualdirs\bob. There's a script in the bob folder (script.asp) that contains just: <!--#include virtual="../index.asp"--> I'm noticing different behaviors between IIS5 and IIS7 when I attempt to run the script by going to http://SiteName/bob/script.asp: IIS5 references the parent path of the site, and imports c:\inetpub\SiteName\index.asp. IIS7 references the parent folder of the virtual directory, and looks for a c:\virtualdirs\index.asp (that doesn't exist). Doing a Response.Write of a Server.MapPath confirms this. Is there a way to get IIS7 to behave like IIS5 in this regard? Unfortunately, moving index.asp and its logic into the virtualdirs folder isn't an option as the virtual directory will be shared across many sites (with differing index.asps). Thanks.

  • Mapped networkdrive on logout

    - by Robuust
    I'm using a script to keep a mapped networkconnection alive, but ofcourse the mapped connection is gone when I logout. The point is now, that I'm running this on Windows Server 2008 R2, where I use remote desktop to login on the administrator account. However, it should remain logged in and not remove the mapped connection as this script takes care of not logging out on MS office 365 sharepoint. Is there a way to keep the mapped networklocation (L:) available after logout? So the script can run to remain the connection? # Create an IE Object and navigate to my SharePoint Site $ie = New-Object -ComObject InternetExplorer.Application $ie.navigate('https://xxx.sharepoint.com/') # Don't need the object anymore, so let's close it to free up some memory $ie.Quit() # Just in case there was a problem with the web client service # I am going to stop and start it, you could potentially remove this # part if you want. I like it just because it takes out a step of # troubleshooting if I'm having problems. Stop-Service WebClient Start-Service WebClient # We are going to set the $Drive variable here, this is just # going to tell the command what drive letter to map you can # change this to whatever you want (if you change it to a # drive that is already mapped it will overwrite it, so be careful. $Drive = "L:" # You can change the drive destiniation to whatever you want, # it has to be a document library or folder of course. $DrvDest = "https://xxx.sharepoint.com/files/" # Here is where we create the object to map the network drive and # then map the network drive $net = New-Object -ComObject WScript.Network; $net.mapnetworkdrive($Drive,$DrvDest) # That is the end of the script, now schedule this with task # scheduler and every so often and you should be set.

  • redirect temporarily STDOUT to another file descriptor, but still to screen

    - by Carlos Campderrós
    I'm making a script that executes some commands inside, and these commands show some output on STDOUT (and STDERR as well, but that's no problem). I need that my script generates a .tar.gz file to STDOUT, so the output of some commands executed in the script also go to STDOUT and this ends with a not valid .tar.gz file in the output. So, in short, it's possible to output the first commands to the screen (as I still want to see the output) but not via STDOUT? Also I would like to keep the STDERR untouched so only error messages appear there. A simple example of what I mean. This would be my script: #!/bin/bash # the output of these commands shouldn't go to STDOUT, but still appear on screen some_cmd foo bar other_cmd baz #the following command creates a tar.gz of the "whatever" folder, #and outputs the result to STDOUT tar zc whatever/ I've tried messing with exec and the file descriptors, but I still can't get it to work: #!/bin/bash # save STDOUT to #3 exec 3>&1 # the output of these commands should go to #3 and screen, but not STDOUT some_cmd foo bar other_cmd baz # restore STDOUT exec 1>&3 # the output of this command should be the only one that goes to STDOUT tar zc whatever/ I guess I'm lacking closing STDOUT after the first exec and reopen it again or something, but I can't find the right way to do it (right now the result is the same as if I didn't add the execs

  • Rundeck get verbose output of command executing on node

    - by Leon Stafford
    I have Rundeck executing a remote script, which is in python is using print statements to return output normally such as: $ python mytest.py PASS: Condition 1 passed PASS: Condition 2 passed PASS: and so on... When I run this via Rundeck, however, it doesn't show me the same print generated outputs as above. In Rundeck's most detailed Debug output mode, I only receive the following: 06:31:12 Permanently added 'myremotenode.com' (RSA) to the list of known hosts. 06:31:12 SSH_MSG_NEWKEYS sent 06:31:12 SSH_MSG_NEWKEYS received 06:31:12 SSH_MSG_SERVICE_REQUEST sent 06:31:13 SSH_MSG_SERVICE_ACCEPT received 06:31:13 Authentications that can continue: publickey,password,keyboard-interactive 06:31:13 Next authentication method: publickey 06:31:13 Authentication succeeded (publickey). 06:31:13 /cygdrive/c/Program Files (x86)/Mozil... 06:32:06 Adding reference: ant.PropertyHelper 06:32:06 Setting project property: sshexec.output -> /cygdrive/c/Prog... I know that the remote script is actually executing just as usual, as I'm receiving other emails generated by the ~30min long script. Obviously, I don't want to have to wait 30mins to see the result of each print statement within the python script. How can I get the same level of output in Rundeck as I do in the bash shell directly?

  • Launching Installer Via Powershell and WinRM and Nothing Happens

    - by Nick DeMayo
    I'm currently working on a Powershell script to run some Microsoft Hotfix installers remotely on several Windows Server 2008 R2 servers that I manage. Basically, the script copies all the appropriate files up to the server, and then runs the installer via Invoke-Command, like so: function InstallCU { Write-Host "Installing June 2013 CU..." Invoke-Command -ComputerName $ServerName -ScriptBlock { Start-Process "c:\aaa\prjcusp2\ubersrvprj2010-kb2817530-fullfile-x64-glb.exe" -ArgumentList "/passive" } } If I run the "Start-Process" command locally on the server, the installer runs properly. However, when trying to run it remotely, nothing happens (actually, I can see the installer start up in Task Manager, but it closes a couple seconds later and doesn't run). I've attempted giving the Invoke-Command -Credentials, I've turned off UAC on the server, and I've ensured that my WinRM settings (running 'winrm quickconfig' and setting TrustedHosts to *) are correct. I've also tried having the Invoke-Command script run a local Powershell script to run the installer and changing the Argument from '/passive' to 'quiet' (in case it can't remotely launch something that has a UI), but again, no dice. Is there anything else I can try, or am I just not going to be able to do this?

  • Permissions Required for Sharepoint Backups

    - by Wyatt Barnett
    We are in the process of rolling out an extranet for some of our partners using WSS 3.0 as the platform. We already use it internally for a variety of things, and we are using the following powershell script to backup the server: param( $url="http://localhost", $backupFolder="c:\" ) [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.SharePoint") $site= new-Object Microsoft.SharePoint.SPSite($url) $names=$site.WebApplication.Sites.Names foreach ($name in $names) { $n2 = "" if ($name.Length -eq 0) { $n2="ROOT" } else { $n2 = $name } $tmp=$n2.Replace("/", "_") + ".sbk" $saveas = "" if ($backupFolder.Length -eq 0) { $saveas = $tmp } else { $saveas = join-path -path $backupFolder -childPath $tmp } $site.WebApplication.Sites.Backup($name, $saveas, "true") write-host "$n2 backed up to $saveas." } This script works perfectly on the current installation running as our domain backup user. On the new box, it fails when ran as the backup user--claiming "The web application located at http://extranet/" could not be found. That url does, in fact, work so I'm fairly certain it isn't anything that dumb and rather is some permissions issue. Especially because, when executed from my security context, the script works perfectly. I have tried making the backup user a farm owner, as well as added him to the various site collection admin groups on the extranet. The one major difference between the extranet and the intranet server is that the extranet has an alternative access mapping (for https://xnet.example.com) and also uses forms authentication for that mapping. Anyhow, what permissions (or other voodoo) do I need to setup to get this script to work properly?

  • How can I mount an AES-128 encrypted DMG file using the NTFS file system under Windows XP?

    - by flarn2006
    I found HFSExplorer, which can handle encrypted DMG files, but it only supports HFS, and the DMG I want to open is NTFS. I can't just use any image mounter since the DMG file is encrypted, and I don't want to need to copy it over to my main hard drive first. (The DMG is on an external hard drive.) If copying it is the only way, however, I'd be willing to settle for that, but I'd rather just leave it on the external hard drive in an encrypted form.

  • Estimating compressed file size using a list parameter

    - by Sai
    I am currently compressing a list of files from a directory in the following format: tar -cvjf test_1.tar.gz -T test_1.lst --no-recursion The above command will compress only those files mentioned in the list. I am doing this because this list is generated such that it fits a DVD. However, during compression the compression rate decreases the estimated file size and there is abundant space left in the DVD. This is something like a Knapsack algorithm. I would like to estimate the compressed file size and add some more files to the list. I found that it is possible to estimate file size using the following command: tar -cjf - Folder/ | wc -c This command does not take a list parameter. Is there a way to estimate compressed file size? I am also looking into options like perl scripts etc. Edit: I think I should provide more information since I have been doing a lot of web search. I came across a perl script(Link)that sort of emulates the Knapsack algorithm. The current problem with the above mentioned script is that it splits the files in their original state. When I compress the files after splitting them, there are opportunities for adding more files which I consider to be inefficient. There are 2 ways I could resolve the inefficiency: a) Compress individual files and save them in a directory using a script. The compressed file could provide a best estimate. I could generate a script using a folder of compressed files and use them on the uncompressed ones. b) Check whether the compressed file's size is less than the required size. If so, I should keep adding files until I meet the requirement. However, the addition of new files to the compressed file is an optimization problem by itself.

  • How to index filenames, size and basic informations for every file on a network?

    - by Antoine
    I have several machines, most of then are Linux and one of them is under Mac OS X. Each machine has several internal hard drives, and I also have a few external hard drives. How can I reliably find files with setup ? External drives are not always plugged, but the files don't move often. Ideally I would like to be able to search the metadata given with the 'file' command, and move files over the network.

  • CDN Rerouting on 404 (file not yet in synch with original storage)

    - by Alan Ristic
    Here is the problem. I've setup my app(on EC2) to store uploaded images directly on Amazon S3. I'd like to be able to serve static files(cdn) from my 'home' server so I wrote script that does sync from S3. But there is a window of (at least) one minute in synch. Now I see two solutions on the problem of pics not been available on 'home' server here: 1.I write script on EC2 (where the app resides) to fetch from DB pics that have status of "not-yet-synch", which is default state when user uploads picture. The script then does a ping to picture and if it gets OK response, updates DB from "not-yet-synch" to "synch". 2.Prefered solution would be to let apache (in this case) redirect request for an image if it sees 404 (e.g. doesent find image requested) to S3. This way I wouldn't need script from solution 1. So what approach do you suggest I take in solving this redundancy problem? Or what is practice in production environments? To further clarify; I'd like so serve images first from 'home' server, if that fails serve them from S3. Tnx, Alan

  • Unable to force Debian to do unattended install... libc6 wants interactive confirm

    - by JD Long
    I'm trying to create a script that forces a Debian Lenny install to install the latest version of CRAN R. During the install it appears libc6 is upgraded and the install wants interactive confirm that it's OK to restart three services (mysql, exim4, cron). This process HAS to be unattended as it runs on Amazon's Elastic Map Reduce (EMR) machines. But I'm running out of options. Here's a few things I've tried: This previous question appears to be exactly what I'm looking for. So I set up my install script as follows: # set my CRAN repos... yes, I know there's a new convention where to put these. echo "deb http://cran.r-project.org/bin/linux/debian lenny-cran/" | sudo tee -a /etc/apt/sources.list echo "deb-src http://cran.r-project.org/bin/linux/debian lenny-cran/" | sudo tee -a /etc/apt/sources.list # set the dpkg.cfg options per the previous SuperUser question echo "force-confold" | sudo tee -a /etc/dpkg/dpkg.cfg echo "force-confdef" | sudo tee -a /etc/dpkg/dpkg.cfg export DEBIAN_FRONTEND=noninteractive # add key to keyring so it doesn't complain gpg --keyserver pgp.mit.edu --recv-key 381BA480 gpg -a --export 381BA480 > jranke_cran.asc sudo apt-key add jranke_cran.asc sudo apt-get update # install the latest R sudo apt-get install --yes --force-yes r-base But this script hangs with the following request for input: OK, so I tried stopping the services using the following script: sudo /etc/init.d/mysql stop sudo /etc/init.d/exim4 stop sudo /etc/init.d/cron stop sudo apt-get install --yes --force-yes libc6 This does not work and the interactive screen comes back, but this time with only cron listed as the service that must be restarted. So is there a way to make libc6 just restart these services with no user input? Or is there a way to stop cron so it does not cause an interactive prompt? Maybe a creative option I've never thought of? Keep in mind that this system is brought up, some Hadoop code is run, and then it's torn down. So I can put up with side effects and bad behavior that we might not want in a production desktop machine or web server.

  • how to make soulseek portable?

    - by Fuxi
    hi all, i was wondering if it's possible to run soulseek as portable on an external hd? the main problem is that soulseek is using local paths to "documents and settings" which means it can't be portable unless i'm copying those files every time. i've tried RegRapper but it seems that it's not possible to map the "document and settings" folder to the external hd. any ideas how it could be done? thx

  • Setting up a Network Bridge on Linux VM (Windows 7 Host)

    - by GrandAdmiral
    I would like to use NetEm to simulate a low bandwidth environment while testing an Internet-connected device. My plan is to setup a bridge in a Linux VM (Linux Mint 13) on a Windows 7 host. Unfortunately I'm having trouble setting up the bridge. Then I can use NetEm in the Linux VM to limit the bandwidth to an external device. I went with the following script: ifconfig eth0 0.0.0.0 promisc up ifconfig eth1 0.0.0.0 promisc up Then create the bridge and bring it up: brctl addbr br0 brctl setfd br0 0 brctl addif br0 eth0 brctl addif br0 eth1 dhclient br0 ifconfig br0 up When I run that script, I see the following warning: Rather than invoking init scripts through /etc/init.d, use the service(8) utility, e.g. service smbd reload Since the script you are attempting to invoke has been converted to an Upstart job, you may also use the reload(8) utility, e.g. reload smbd The device connecting to the bridge is able to obtain an IP Address, but it can only ping the IP Address of the bridge (both are 10.2.32.xx). Then after a few minutes, other parts of our network go down. I'm not sure why, but once I kill the bridge the network is fine. Is it possible to setup a network bridge in a Linux VM? Do I need to do something else with the dhclient br0 part of the script? By the way, I'm using VirtualBox. The wired connection is eth0 and the wireless connection is eth1. The wired connection is connecting to the device and the wireless connection is going to the network. Both adapters are set up as bridged adapters with promiscuous mode set to "allow all".

  • Getting the local IP address in Ubuntu 10.04 LTS

    - by Andreas Grech
    I am trying to get my locally assigned IP address from Ubuntu 10.04 LTS with ifconfig and what I'm getting is my external IP address (in other words, it's the same IP I see on whatismyip.com) When running ifconfig eth0, inet addr shows my external IP address instead of the local address. How do I get my local IP address ?
