[Pkg-nagios-devel] nagios-nrpe-server

[Csikos Balint]

Hi all!

At my workplace we are using nagios, nrpe monitoring. Mainly on x86_64 
arch, but there are some 32 bit systems too. We have found an 
interesting bug, that we beleive, has some connection with the 32bit 
nagios-nrpe-server package.

mtsearch:/var/cache/apt/archives# dpkg -I nagios-nrpe-server_2.5.1-3_i386.deb

  Description: Nagios Remote Plugin Exectutor Server
   Nagios is a host/service/network monitoring and management system.
   .
   The purpose of this addon is to allow you to execute Nagios plugins on a
   remote host in as transparent a manner as possible.
   .
   This program runs as a background process on the remote host and processes
   command execution requests from the check_nrpe plugin on the Nagios host.


There is a script gives back 2 lines.

#!/bin/bash

echo alma
echo korte
exit


And the nrpe daemon configured to execute this on command /resolvconf/. 
If I execute (as nagios user) on the local machine (mtsearch) it gices 
back the 2 lines. But if I execute from a remote machine (nagios01a) it 
gives back only 1 line.

nagios at nagios01a:~$ /usr/lib/nagios/plugins/check_nrpe -n -H mtsearch -c resolvconf
alma
$

On all 32 bit debian machines the result is the same. Unfortunately we 
cannot use the amd64 package/binary. I am expecting, that 
compile/configure option(s) differs in the 2 packages (i686-amd64).

Best regards,
Balint Csikos
