tcpdump -npi [ifname, exp0 for example] -X -s220

You can throw other parameters in such as:

host 100.2.3.4 and port 80

There are some other commands that you can use to
filter it down to a specific stream as well if that
isn't good enough.

If I am looking for something specific, I will
redirect it to a file with:

> /home/dump.txt

for example and then grep for whatever I am looking
for.
