Network / traffic Monitor Software ?

[ArealPerson]

Hi,

I'm new to linux, I'm running Fedora Linux ver 12.

I'm looking for a freeware/shareware software program that will allow me to see who is
on/using my wireless network, if anyone is sneeking around my wireless bubble.

Does anyone know of a software for Linux to do that ?

Thanks,
Areal

Question:
How can you not know?
Is that a bigger wifi, where many people can login?
or (I hope not) a open wifi?

In any case, if the clients get their IP via dhcp, then just look at the leases.

I'm sorry, but that really has nothing to do with my post.

I'm looking for a freeware/shareware Network Monitoring software
that will help me ident hackers/snoopers or anyone who is currently
using my wireless network by displaying network traffic data on the screen.

I wouldn't say it has nothing to do with your question, since it could show people connected to your wireless connection just by looking in the GUI for the router, and if your router supports it you could enable logging and see the IP's and match them to the machines on your network that you know.

Regardless, you should check out wireshark and snort.

Download a program called Cain and Abel, you can sniff network traffic using that, only one I can think of without downloading anything onto the other systems.
