Use wireshark if you are logged in with a gui. In text mode use
tcpdump. In either you can specify a filter with protocol, source
and/or destination addresses and port number. Something like
tcpdump -i eth0 udp
might be enough if you don't have a lot of traffic or
tcpdump -i eth0 udp and port portnumber
to narrow it down more.
