The example (real world debug)
callflow can be viewed
at my development website: http://stage.august.net/sip1_index.html
and
http://stage.august.net/sip1.html
You use tcpdump (or ethereal, or whatever) to grab the
Output, like on linux:
tcpdump -s 0 -i eth0 'port 5060' -w /var/log/sip1.dump
Hello!
How do you capture from different networks? Is it possible to input
several dump-files into the tool, one captured at the caller site and
one captured at the callee site?
regards,
Klaus

I don't know.
I know there are tools for joining tcpdump files,
perhaps it is possible.
On our setup we have cisco switches. We 'port monitor'
all of the ports we want to gather information about.
So, even when they are on different networks we get all of
the packets.

In theory you can use mergecap (part of ethereal) to merge captures from
different networks. In practise this is difficult b/c you are likely
missing a common timebase to determine the correct relative ordering.
Locally to sniff on N networks, I put N extra network adaptor cards in
my desktop machine and do NOT configure the IP level interface. Using
them strictly as monitoring interfaces, this ''multihomed'' machine can
sniff all N networks at the same time, solving the time-base problem.

Hey Alan,
I'm about to order one of your boxes.
I hope it works :-)

If you use ntp on all the machines you shouldn't have any problem merging
the capturefiles.
