Hello,

I'm using tethereal with colinfo to display an M3UA capture session and
display TSN within SCTP frames. It works just fine. I use the following
command (traces.ethereal being the capture file):
tethereal -r traces.ethereal -z "proto,colinfo,sctp.tsn,sctp.tsn"

In the middle of those SCTP/M3UA packets, I also have some proprietary
packets (UDP based).
How can I display the UDP data (as hex or ASCII), using colinfo?

When I try: 
tethereal -r traces.ethereal -z "proto,colinfo,udp,udp"
I'm getting a core dump (gdb back trace shows that the stack was
"tap_push_tapped_queue()/protocolinfo_packet()/proto_alloc_dfilter_string()"
).
This is tethereal 0.9.8.

Do I need to write a parser for this protocol (just ASCII strings)?

Thanks!
Olivier.
