If you are using the Linux server as your gateway, you can then configure iptables (or ipchains) to block traffic from the IP that's using up a lot your bandwidth. -Paul Kurczaba ----- Original Message ----- From: "Mike" <mike () superiorholidayadventures ca> To: "Cheetah" <cheetahx () online no>; <security-basics () securityfocus com> Sent: Wednesday, December 03, 2003 4:21 PM Subject: RE: Identifying a computer How are you sharing your bandwidth?

I am helping the sysadmin on my local LAN to manage the network, etc. We have limited internet-bandwidth, and therefore it is necessary to
make
sure no-one is taking to much of the bandwidth, as others will not be able to use
the
internet connection. For the last 2 days, a new IP has appeared, and it is constantly using
a
lot of bandwidth. We have a linux-server running DHCP, DNS and the internet-connection.
I
have checked the dhcpd.leases file, but the IP isn't there. I have also tried to ping
and
scan this IP, but the computer is running a strong firewall, shows no open ports and doesn't even
respond
to pings. Is there any way I can get some information out of this computer
without
running around and asking everyone what their IP is? Tore
