How to sniff wireless networks?

Asked by tashi

Hi to you all,

I use Ubuntu 9.10, and:
1) I'd like to know how to, with "jnettop -p -i wlan1" (my wireless interface) remove the lines which are about myself?

2) I'd like moreover to know how to detect on this wireless network which IP connects onto which website? I would just like to know the name of the program to use to know it, because I'll manage to get it (in .tgz by a google search, or maybe even with apt-get), just the name would be enough yet...

Thanks to please help me about that,
good bye!
