Hi Gilbert,
Thanks for helping me out on my last problem. It was solved, thanks to
you!
Well, today I bumped into another problem, which I am sure is really a
small one.
I am trying to print out the PROTOCOL & INFO column for the two
protocols I have. I am able to do so with Proto1 (which is on top of
ethernetII) , but I am not able to do so for Proto2(which is on top of
Proto1).
I have tried almost everything, even pasting the same code in Proto2,
but it just doesn't work. Please help me out!
Here is what I am doing:
if(check_col(pinfo->cinfo, COL_PROTOCOL))
col_set_str(pinfo->cinfo, COL_PROTOCOL, "PROTO2");
Also, I have tried col_clear, col_add_str and col_append_str and none of
these work for PROTO2, while they all work perfectly for proto1!
Thanks and Best Regards,
Sahil

Does the PROTO1 dissector call dissector_try_port()? That's needed for
the next registered protocol dissector to be called.
