Hi Jon,
thank you for getting back on me. Of course I did do a su - nagios for
my tests. I fact all my console tests run fine. I think it's Nagois
doing some kind of su in its internals which causes my plug-in to get a
wrong $HOME inherited. The bad behavior only occurs when executed by the
actual Nagios setup.
Best,
Alex

Alexander,
It sounds like you are saying that you login as root, then su to
nagios. If that's the case, make sure that you use su - nagios
The hyphen tells su to use the environmental variables of the user
that you are switching to. Without using the hyphen, it continues to
use the environmental variables of the base user (root in this case).

Hi Nagios users,
this is my first post. I encountered a behavior I am not able to
understand. Well, I guess I did understand it, but I don't know how to
counter it :)
When I write a plug-in for Nagios it is executed as nagios:nagios. Yet
$HOME is set to "/root".
My /etc/password and nagios's home-directory are ok. It works well when
I log in as user nagios and execute the plug-in there.
I did expect to find some attributes for command definitions to set the
home directory, but I could not find any.
I guess the whole thing has to do with su and the way it does (not)
handle the home directory or environment in general.
Currently I work around that behavior using this code:
if [ "$HOME" == "/root" ] && [ "`whoami`" == "nagios" ]
then
HOME="/usr/local/nagios"
fi
But as you might guess I am not very satisfied.
Thanks in advance,
Alex
