>From a quick scan through the script I can see two problems -
*) UNKNOWN is return code 3, not -1. This can lead to a "return code
127 is out of bounds" type error if the script hits its timeout of 20
seconds. This can be amended on line 13.
*) Assumptions are made that the current directory (where the script is
run from, in your case "/usr/lib/nagios/plugins/contrib/") is writable
by the user running the script, since it tries to create some temporary
files. This can be fixed by changing all occurances of "tmp_res1",
"tmp_res" and "tmp_html" to include the full path to the tmp directory,
i.e. "/tmp/tmp_res1". A better fix would be to use File::Temp and
possibly the "tmpnam" function (for security reasons), buts that's
personal preference.
If that does not fix your problem, please repost your current command,
service and macro definitions as the error implies that the url is not
being passed to the command - around line 26 you could add the following
to help catch this
if(!$url) {
print ("ERROR: no valid url provided\n");
exit $ERRORS{"UNKNOWN"};
}
