What is your command line? Are you calling the script directly or is it wrapped
in a shell script? I took a quick look at the script, and it needs quite a bit
of improvement. Not sure if it was a result of my copy and paste, but there is
only so much I can blame on bad formatting. I would recommend looking for a
different script that does the same thing.

Umm... Not sure. I just tried uncommenting and got the same results though.
I'm taking over managing the nagios server that we have from another collegue
who left the company. I've actually migrated everything over to another server
that is now running the latest nagios. The previous server was 3.0.6 I
believe. I tried searching for an updated version of these plugins, but
couldn't find any. I'm not that great with perl scripting either. :/

Subject: [Nagios-users] nagios plugins return code issue
Hello all,
I've googled around everywhere trying to find an answer here and came up
unsuccessful, so if anyone has had experience in this situation, I'd appreciate
help!
Basically, the issue that I'm having is that I have a couple of temperature
plugins that are reporting errors in Nagios and at the command line they're
exiting in 0:
check7204temp.pl - Return code of 255 is out of bounds and checkciscotemp.pl -
Return code of 9 is out of bounds
If I run a "echo $?" at the command line after running the command successfully,
I get 0.
Thanks for any help anyone can provide!! My perms are 755 and nagios user owns
the plugins and I've run successfully with nagios user and got 0 output. I'm
really stumped!!
Here's the code for the plugins:
