AIX server 7.2 permission denied error nagiosxi

[mejokj]

Hi Team,

We have tried to add AIX server 7.2 to Nagioxi using check_by_ssh plugin. But we are getting the below permission issue.

Error
++++

[nagios@fujams01 ~]$ /usr/local/nagios/libexec/check_by_ssh -H drcoreflsh01 -C /usr/local/nagios/libexec/check_disk
Remote command execution failed: ksh: /usr/local/nagios/libexec/check_disk: 0403-006 Execute permission denied.

Please check and advise on this issue.

Followed the same document mentioned below.

Note: We are able to do passwordless authentication to remote server and the command /usr/local/nagios/libexec/check_by_ssh -H remoteip -C uptime works fine.

You provided a directory listing of /home/nagios but the plugin would be found in /usr/local/nagios/libexec/check_disk on the AIX machine. Please get a directory listing of that. I'd also like to see a copy of the /usr/local/nagios/libexec/check_disk as well. It looks like it is trying to run ksh - is this shell available on the AIX system? A check_disk script using bash can be found at https://support.nagios.com/forum/viewto ... 16&t=40948 if you'd like to test that.

We have copied these files directly from nagios xi server, it was available by default in nagios xi server. Please see below the file format used.

root@drcoreflsh01:/usr/local/nagios/libexec # file check_users

root@drcoreflsh01:/usr/local/nagios/libexec # file check_procs

root@drcoreflsh01:/usr/local/nagios/libexec # file check_by_ssh
check_by_ssh: ELF 64-bit LSB version 1 executable

=======================================================================================
Default shell used is ksh for all users

root@drcoreflsh01:/usr/local/nagios/libexec # lsuser -f root | grep -i shell
shell=/usr/bin/ksh
root@drcoreflsh01:/usr/local/nagios/libexec # lsuser -f nagios | grep -i shell
shell=/usr/bin/ksh

=======================================================================================

We have used the check_disk script using bash from viewtopic.php?f=16&t=40948 . It works fine and provided us the expected output.

root@drcoreflsh01:/usr/local/nagios/libexec # file check_disk
check_disk: shell script

[nagios@fujams01 ~]$ /usr/local/nagios/libexec/check_by_ssh -H drcoreflsh01 -C '/usr/local/nagios/libexec/check_disk 80 85 /opt'

OK: '/opt' is at 33% capacity, total 4.0GB, used 1.3GB (32.9%), free 2.7GB (67.1%) | 'used space'=2760440B;6710886;7130316;0;8388608 'used space (pct.)'=32.9%;80;85;0;100

Do we have similar type of plugins which can provide cpu usage, users,procs etc.

Please suggest

Thanks

The plugins being copied over is going to be the problem. The plugins were compiled for a different system. You'll need to compile them for/on the AIX system.

The source can be downloaded from https://nagios-plugins.org/.

Another option is to use scripts instead of compiling binaries.

The exchange will have some plugins:

https://exchange.nagios.org/directory/P ... ystems/AIX

as does the NRPE agent(https://assets.nagios.com/downloads/nag ... ent.tar.gz). I've attached the plugins that come with this agent.
