Nagios is good at what it does, and it really sounds like this just 
isn't it.

However, I don't see a reason you couldn't hack together a really simple 
check using a tool that *is* good at this sort of thing (like, say, 
nmap), and based on the results of that tool, feed the results back to 
Nagios .
