[icecast] my icecast problem

[Kelly Lee Myers]

Quick question?
Is there a way to observe the TCP/IP block numbers produced by a client
connected to a server that is not getting data fast enough or too fast in
icecast while it happens in real time? I suppose you might be able to do
this with a sniffer of some sort but I am just wondering about the accuracy
of the results. Having access to this information in real time would help
with trouble shooting. I know it did with our server development and as a
broadcaster I can watch each connection and see who is having problems
without going through the logs. If there is, can someone tell me how this
can be done? cause I would like to try this out and duplicate the problem
and watch what is really going on...
In addition is there a way to set the size of the outgoing packets or is
that completely handled by the stack and not icecast itself. Forgive me if
that sounds stupid, but I didn't really get that deep into icecast
configuration.

Thanks in advance.

Lithium.
