You should watch your network traffic when you are bored

Have you ever wondered how much traffic a specific protocol generates? For example, I listen to Internet radio all of the time and I always wonder "what does the traffic pattern look like?". Well it's easy in Linux just do the following:

sudo tcpdump -i wlan0 -w cap1.dump

then press Ctrl - C to end capture. Then just use wireshark to look at the traffic pattern. Wireshark is a wonderful tool.
