See the sudoers file or the man pages for an explanation. There are things that sudo passes by default and things that need to be manually added. I assume a security reason. Basically in sudoers, you can add environment variables to pass through in different cases. <br><br></font><br> <br>

<div class="moz-cite-prefix"><tt>Well... I figured out it has to do
with how sudo invokes the environment. I'm pretty sure there is
a parameter I could supply to sudo to bring in the environment,
but it was just as easy to switch from sudo to su.<br>
<br>
I changed my commands to:<br>
su - xymon -c "/home/xymon/client/runclient.sh start"<br>
and it works now.<br>
<br>
If anyone who understands this better than me understands why, I
would appreciate an explanation.<br>

an init script that is starting up the xymon client. It
starts, and runs, however it doesn't appear to have any
access to any environment variables. If I restart the
client from a shell, it takes off and runs fine. I've got
echo statements in the init script to display some of the
environment variables I need, and they are displaying fine
at boot time. It just seems that xymon doesn't have
access to them when it is running. What has me really
confused is that I'm even exporting the variable from a
file directly from the xymon script.<br>
<br>
For example, in the init script, I 'echo $HOST' The host
name shows up in the log<br>
I have a perl script that clientlaunch calls, I have a
variable "my $host = $ENV{"HOST"}.<br>
<br>
I am printing the "HOST" variable out to the log file when
the script runs. If I start the xymon client from a
shell, the HOST variable prints out. However, it doesn't
print out (just a blank) if the xymon client starts via
the init script.<span class="HOEnZb"><font color="#888888"><br>
