Specifically how are you determining that the call to lynx is failing?
I know you mentioned that it seems that all network I/O is not functioning from within the plugin, but did you test using curl instead of lynx?
[EMAIL PROTECTED] 1/5/2005 2:15:45 PM >>>OK, I discovered two problems. First, some background. My script queries an HTTP-based temperature sensor using the Lynx utility and returns the result as a printed number as the sole output of the script. It runs fine on the desktop.
When I run my script as a cmd-line plugin, it correctly retrieves the results and prints the answer to stdout, but nothing is displayed in Intermapper. I verified this by outputing in parallel to a text file and tailing the file. So the cmd-style plugin appears to ignore all output.
When I run my script as a Nagios plugin the call to Lynx fails. It appears that Intermapper does not permit Lynx to open a TCP socket, or perhaps Lynx isn't invoked at all. I tried hard-coding the path to Lynx, and also putting a symlink to links in the Intermapper Tools folder, but to no avail. I can invoke other shell utilities, such as date and cat, but not anything that does network I/O. If I output dummy text from my script, that text shows up in the "Reason:" field of the status pop-up, so basic plugin connectivity appears to work with Nagios.
I really need to use the Nagios version so that I can pass user-coded parameters into the script, something you can't do with the cmd type plugin.
Ideally, I'd like to be able to graph the temperature returned as well, but I realise that IM doesn't appear to support that for non-SNMP probes. I'd think it would be easy to do using pseudo-MIB variables, however, so I'm hoping that something is in the works along those lines.

I've followed the Nagios standard of writing the value to stdout on a single line, but the value never appears in the IM device's description or any other place that I can find.
Am I missing something?
It _should_ show up as the "reason" in the status window when you open
