Post output here of error when su - nagios

when i try to use the command su - nagios...... nothing happens!!

Code: Select all

root@maestro:~# su - nagios
root@maestro:~# 

and i don't know why the command:

Code: Select all

id nagios
uid=121(nagios) gid=124(nagios) groups=124(nagios)

why i can't switch to nagios user but the command id nagios says the information above?

Forums ate my first response - I had to re-type it (although it may have been a Layer 8 problem here ).

You're getting the same error from the plugin as your command and service definitions are synonymous - they're both exactly the same. Welcome Nagios! It's like Perl sometimes - many different ways to skin many different cats!

Firstly - make sure the plugin you're executing on the remote server has the execute bit set:

Code: Select all

ls -l /usr/local/nagios/libexec/check_nagios

Secondly, there's clearly something wrong with your local "nagios" user. Can you provide the output from:

Code: Select all

getent passwd nagios

ok on my remote server backups:

Code: Select all

root@backups:/usr/local/nagios/etc# ls -l /usr/local/nagios/libexec/check_nagios-rwxr-xr-x 1 nagios nagios 124350 mag 19 12:02 /usr/local/nagios/libexec/check_nagios

and on nagios server (implemented not by me ) :

Code: Select all

root@maestro:/usr/lib/nagios/plugins# getent passwd nagios
nagios:x:121:124::/var/lib/nagios:/bin/false

oh what does it mean?
