cristian: since the fish is too big to post it, here is how to fish it:

1. create two simple bash scripts using the files I am going to attach
a. client.sh
b. server.sh
(you need the famous "netcat" for them to work)

2. have a look at them to make sure I am not trying to break into your machine
or something :-). after that make them executable and start them; first the
"server.sh", second the "client.sh"

3. start tcpdump like this:

tcpdump -s0 -w /tmp/tcp.pcap -neli lo

make sure you have enough space on the partition where it saves the file.
also: both scripts are quite cpu hungry.
depending on how fast your machine is you'll get enough packets in several
seconds (wow!), minutes or hours (no...). I am testing with a little bit over
500k packets.
