  • Nagios command not transmitting all arguments

    - by markus
    I'm using the following service to monitor our postgres db from nagios: define service{ use test-service ; Name of servi$ host_name DEMOCGN002 service_description Postgres State check_command check_nrpe!check_pgsql!192.168.1.135!test!test!test notifications_enabled 1 } On the remote machine I've configured the command: command[check_pgsql]=/usr/lib/nagios/plugins/check_pgsql -H $ARG1$ -d $ARG2$ -l $ARG3$ -p $ARG4$ In the syslog I can see that command is executed, but there is only one argument transmitted: Oct 20 13:18:43 DEMOSRV01 nrpe[1033]: Running command: /usr/lib/nagios/plugins/check_pgsql -H 192.168.1.134 -d -l -p Oct 20 13:18:43 DEMOSRV01 nrpe[1033]: Command completed with return code 3 and output: check_pgsql: Database name is not valid - -l#012Usage:#012check_pgsql [-H <host>] [-P <port>] [-c <critical time>] [-w <warning time>]#012 [-t <timeout>] [-d <database>] [-l <logname>] [-p <password>] Oct 20 13:18:43 DEMOSRV01 nrpe[1033]: Return Code: 3, Output: check_pgsql: Database name is not valid - -l#012Usage:#012check_pgsql [-H <host>] [-P <port>] [-c <critical time>] [-w <warning time>]#012 [-t <timeout>] [-d <database>] [-l <logname>] [-p <password>] Why are arguments 2,3 and 4 missing?

  • Vagrant - Failed login, ssh not set up

    - by motleydev
    This question is two fold because somewhere in my attempts to solve the problem, I created a new one. First: I was trying to vagrant up using a Vagranfile based on the standard hashicorp/precise32 box. Everything worked up until default: SSH auth method: private key where it would eventually time out. Enabling gui in the Vagrantfile showed that the machine never actually logs in. I can use the standard user/pass and log in from that point but the vagrant up process still remains at that prior status. Here's where my understanding might be a little dim. I've tried setting auth method from the insecure_pass_key to my root ~/.ssh/id_rsa or whichever one I wanted to use. I'm not entirely sure where to put a copy of the public key or my authorized keys file. I've got a .vagrant.d folder in my user dir (I'm on OSX) which seems to contain the box images. I've got a .vagrant folder in my directory with the Vagrantfile which seems to contain the specific machine I am building off of. I've tried pouring over the docs and forums but I seem to be missing a key concept here. And Now: After a host of tips/tricks such as rolling back by VirtualBox install, uninstalling/reinstalling Vagrant and VritualBox several times, when I try to run vagrant ssh-config with a Vagrantfile based on the same hashicorp/precise32 it says that the box is not enabled for SSH. Specifically, this error: The provider for this Vagrant-managed machine is reporting that it is not yet ready for SSH. Depending on your provider this can carry different meanings. Make sure your machine is created and running and try again. Additionally, check the output of `vagrant status` to verify that the machine is in the state that you expect. If you continue to get this error message, please view the documentation for the provider you're using. So now I am slightly up a creek. Any help would be appreciated if not just clarifying a concept. Some pertinent info: I'm on OSX Maverics Due to the fact I'm running a dual HD system with system files on one HD and user files on another, my permissions are a little wonky and VBoxManage will only let me run commands via Sudo - not sure if it's pertinent - but maybe. I have no idea what I'm doing. That part is perhaps more important.

  • Run Rails server on client's local machine for single tenancy [on hold]

    - by rigyt
    We are building a Rails application for a client that wants to run the app locally to be close to their data center for best performance. I had assumed we would use a standard web host. What requirements should we demand of the client's infrastructure..all I can think of so far is remote access for developers and a Linux machine? We don't have server admin expertise so would need to contract this, I doubt the client has the expertise. Does this sound like a recipe for disastor?!

  • Process limit for user in Linux

    - by BrainCore
    This is the standard question, "How do I set a process limit for a user account in Linux to prevent fork-bombing," with an additional twist. The running program originates as a root-owned Python process, which then setuids/setgids itself as a regular user. As far as I know, at this point, any limits set in /etc/security/limits.conf do not apply; the setuid-ed process may now fork bomb. Any ideas how to prevent this?

  • procmail don't execute php script

    - by Phliplip
    Hi, I have setup a kannel SMS gateway on my FreeBSD 7.2 - the service works great. I'm now trying to setup a email2sms feature. For this i have created a system user called kannel and all mails are forwarded to this user. In the home dir of kannel i have the following files. -rw-r--r-- 1 kannel kannel 81B 17 jan 09:50 .procmailrc lrwxr-x--- 1 root kannel 58B 14 jan 13:24 email2sms.php @ -> some-what-some-where -rw-rw-rw- 1 root kannel 5,8K 17 jan 09:52 log.email2sms -rw------- 1 kannel kannel 1,3K 17 jan 09:50 procmail.log -rw-r----- 1 root kannel 606B 14 jan 13:28 rawmail.txt The file email2sms.php is a symlink to the a php script (ZendFramework Application) that takes the email from STDIN, and uses ZendFramework to parse that mail into an object. It then do a http request to the SMS gateway. The php-script works. Content of .procmailrc LOGFILE=$HOME/procmail.log VERBOSE=yes :0 | php email2sms.php >> log.email2sms From last sent email i have this in procmail.log procmail: [97744] Mon Jan 17 09:50:40 2011 procmail: [97744] Mon Jan 17 09:50:40 2011 procmail: Assigning "LASTFOLDER= php email2sms.php >> log.email2sms" procmail: Executing " php email2sms.php >> log.email2sms" procmail: Notified comsat: "kannel@:/home/user/kannel/ php email2sms.php >> log.email2sms" From [email protected] Mon Jan 17 09:50:40 2011 Subject: asdf as Folder: php email2sms.php >> log.email2sms 2600 But there is no new output to log.email2sms, and the script should output the subject of the email. If i sudo as the kannel user and pipe a file with raw email to the script, it executes just fine. [root@webserver /home/user/kannel]# /home/user/kannel/ sudo -u kannel cat rawmail.txt | php email2sms.php >> log.email2sms And the command outputs to log.email2sms as desired. Any ideas guys?

  • Passing two arguments to a command using pipes

    - by firebat
    Usually, we only need to pass one argument: echo abc | cat echo abc | cat some_file - echo abc | cat - some_file Is there a way to pass two arguments? Something like {echo abc , echo xyz} | cat cat `echo abc` `echo xyz` I could just store both results in a file first echo abc > file1 echo xyz > file2 cat file1 file2 But then I might accidentally overwrite a file, which is not ok. This is going into a non-interactive script. Basically, I need a way to pass the results of two arbitrary commands to cat without writing to a file. UPDATE: Sorry, the example masks the problem. While { echo abc ; echo xyz ; } | cat does seem to work, the output is due to the echos, not the cat. A better example would be { cut -f2 -d, file1; cut -f1 -d, file2; } | paste -d, which does not work as expected. With file1: a,b c,d file2: 1,2 3,4 Expected output is: b,1 d,3 RESOLVED: Use process substitution: cat <(command1) <(command2) Alternatively, make named pipes using mkfifo: mkfifo temp1 mkfifo temp2 command1 > temp1 & command2 > temp2 & cat temp1 temp2 Less elegant and more verbose, but works fine, as long as you make sure temp1 and temp2 don't exist before hand.

  • What could cause the file command in Linux to report a text file as data?

    - by Jonah Bishop
    I have a couple of C++ source files (one .cpp and one .h) that are being reported as type data by the file command in Linux. When I run the file -bi command against these files, I'm given this output (same output for each file): application/octet-stream; charset=binary Each file is clearly plain-text (I can view them in vi). What's causing file to misreport the type of these files? Could it be some sort of Unicode thing? Both of these files were created in Windows-land (using Visual Studio 2005), but they're being compiled in Linux (it's a cross-platform application). Any ideas would be appreciated. Update: I don't see any null characters in either file. I found some extended characters in the .cpp file (in a comment block), removed them, but file still reports the same encoding. I've tried forcing the encoding in SlickEdit, but that didn't seem to have an effect. When I open the file in vim, I see a [converted] line as soon as I open the file. Perhaps I can get vim to force the encoding?

  • Using a flash drive to speed up conventional disks (on linux)

    - by Daniel
    Hi! Is there a possibility to use a flash drive as a speed up for conventional hard disks? I got the idea to redirect all read ops to the flash drive if the data is already stored there, and to read from the conventional disks if the data is not found there (and during idle time the freshly accessed data from the conventional disk is stored on the flash disk). Is this already possible with linux standard tools?

  • Using gVIM as a replacement for Visual Studio

    - by espais
    Hi all, Is there a good way to get gVim working as an IDE replacement? I'm moreso looking for suggestions for Intellisense-type plugins...code completion...maybe easy directory browsing (other than the standard 'edit.' command). I'm building embedded applications in C...so I have no need to incorporate any debugging elements, and for the build process I can just have a console window open to call my batch file whenever it is required (or if I could call it through some hotkey combination in gVIM...that would be awesome as well).

  • Debootstrap Ubuntu over NFS leads to mknod I/O error

    - by Aaron B. Russell
    Hi everyone, I'm trying to prepare an Ubuntu environment for a diskless machine that will PXE boot and mount an NFS share as it's root. I've currently got another Ubuntu machine mounting the NFS share and I'm trying to debootstrap into it, but it has trouble creating devices over NFS: root@kimiko:~# mount | grep Seiuchi 192.168.0.203:/mnt/user/Seiuchi on /mnt type nfs (rw,addr=192.168.0.203) root@kimiko:~# debootstrap --arch i386 maverick /mnt http://gb.archive.ubuntu.com/ubuntu/ mknod: `/mnt/test-dev-null': Input/output error E: Cannot install into target '/mnt' mounted with noexec or nodev My NFS rule on the unRAID server is 192.168.0.201/32(rw,no_root_squash,sync). I don't have the noexec or nodev options set. I've not got much experience with NFS, so I'm probably missing something basic in the way I'm sharing this, but my attempts at Googling for an answer isn't really turning anything useful up. Does anyone have suggestions on what I might have missed or maybe relevant docs? Edit: Creating normal files (and directories) works just fine, I just can't create devices... root@kimiko:/mnt# mkdir foo root@kimiko:/mnt# cd foo root@kimiko:/mnt/foo# touch bar root@kimiko:/mnt/foo# mknod quux c 4 64 mknod: `quux': Input/output error root@kimiko:/mnt/foo# ls bar

  • newsubtitles line not working in FFmpeg

  • Clarification on Hyper-V licensing, features, and version

    - by gravyface
    As I understand it, you can do: Windows 2008 + Hyper-V role Windows Hyper-V Server (which is free I believe) Windows 2008 Core + Hyper-V Role I'm assuming that Core + Hyper-V and Hyper-V Server have the smallest footprint, and therefore better performing, less patching, etc. What other trade-offs/compromises would there be compared to the full Windows + Hyper-V role? However, I've read somewhere that Enterprise comes with four Enterprise 2008 (4) guest VM licenses (I think Standard gives you two (2)). Can someone clarify these statements?

  • Restarting shell script with &disown using Monit

    - by Solas Admin
    I have a shell script that runs a C++ backend mail system (PluginHandler). I need to monitor this process in Monit and restart it if it fails. The script: export LD_LIBRARY_PATH=/usr/local/lib/:/CONFIDENTAL/CONFIDENTAL/Common/ cd PluginHandler/ ./PluginHandler This script does not have a PID file and we run this script by executing ./rundaemon.sh &disown ./pluginhandler starts the process and starts logging into /etc/output/output.log I stop the process by identifying the process ID with [ps -f | grep PluginHandler] and then killing the process. I can check the process in Monit just fine, but I think Monit is starting the process if it is not running but it can't do &disown so the process ends as soon as it starts. This is the code in the monitrc file for checking this process: check process Backend matching "PluginHandler" if not exist then alert start "PATH/TO/SCRIPT/rundaemon.sh &disown" alert [email protected] only on {timeout} with mail-format {subject: "[BLAH"} I tried to stop the script from terminating by modifying the script like the following but this does not work either. export LD_LIBRARY_PATH=/usr/local/lib/:/home/CONFIDENTAL/production/CONFIDENTAL/Common/ cd PluginHandler/ (nohup ./PluginHandler &) return Any help to write a proper Monit rules to resolve this issue would be greatly appreciated :)

  • Excel Data Organization: Array Formulas? Tables? Named Range?

I don't want to use the Magic Wand because it struggles with half-transparent pixels and because I do have a perfect Alpha Channel. Any ideas how this can be done?
