Hi Jon,<br>
<br>
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.<br>
<br>
Best,<br>
<br>

<div> 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</div>
<div>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).<br>

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