problemes from the internet

i have a computer on my network who is receiving data from the net. I closed the computer, but the trafic is still there.
Is there a way to stop the trafic, or to find out from what ip i get it?

thank you

Could you please tell us if you have a router, firewall, VPN, ADSL, Cable modem, using a share ware -p2p system. FTP running.
Have you downloaded anything from a site called Gator or simular?

Maybe we narrow the serch going from there.....

Our network is like this:

ISP<---->cable modem <---->linux computer<------>our network

we have i firewall but is only checking the mac addresses of the computers and collects data for traffic monitoring.

There is an other linux computer with a ftp server, but i don't know if this helps...
There are no p2p programs.

No Gator downloads.

I hope this answers your questions...

i don't know how to find who is making this...

have you tried running a netstat? How are you sure there is data coming from the internet? Do a tcpdump? Snort?

How do you know you are receiving data?

Just a point your cable modem downstream light will almost definitely constantly flash at various rates such is the Internet.

And what exactly do you mean when you say "I closed the computer" ?
