[expert] Monitoring UDP

[Randy Kramer]

What can I use to monitor UDP data?  My Internet gateway is capable of
continuously sending log messages via UDP.  I'd like to monitor that
data on another machine (interconnected via Ethernet).  Any ideas on
what I use to do that and pointers on how to set it up?

I've looked at the man pages on udp, but that looks like something I'd
have to incorporate in a c program.

Thanks,
Randy Kramer
