    Hello.

    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
