I use a a program called "tcpdump" and visual one "ethereal".

But usually my firewall tells me if someone is trying to connect to my
box remotely from the net.

After you install tcpdump say you access the internet on eth0: try:

tcpdump -n -lnX -s 1500 -i eth0

Hit a website or wait for some traffic, you will see the packet send;
Hope this helps'
