hi friends,

my networking is been granded by p2p tools. i blocked the ports as i saw in a writeup but it not working for me. can any one assist.

All i want to do is to block all clients programs such as LimeWire, BearShare, Shareaza, Gnucleus, Gtk-Gnutella, Acquisitionx, Poisoned, Mutella, Phex, Qtella, Gnotella, XNap and CocoGnut (all of which use the Gnutella protocol) using a Linux firewall.

thanks

You may have more luck turning off everything, and then only turning on the things you really need to use.

Thks for ur responce but p2p clients could connect on a varieties of ports. I have specifically blocked the ports but all to no aveil.

I have been reading on rope which can be used to patch the kernel and iptables to enables the use of certain match strings.

Thanks so much.

If the P2P clients are using ports for other services (example port 80 which you probably want to allow) then there is no way to block them with iptables. You will need a firewall that will actually look into the packet and analyze the data inside it to do that.
