Thread: Message in log

  1. Message in log

    I get this message repeatedly in my new OpenSUSE 10 linux install that I have
    never seen before but has been constant since the new install:

    Mar 21 22:58:08 gemini kernel: martian source 255.255.255.255 from
    172.16.0.254, on dev eth2
    Mar 21 22:58:08 gemini kernel: ll header:
    ff:ff:ff:ff:ff:ff:00:00:c5:c7:a0:74:08:00

    Can someone tell me why I get it and how to get rid of it?
    FYI, I have a DSL connection coming through one nic and out through second nic
    and into a hub which connects multiple XP machines on a samba network.

    The complaint is that there is some host at MAC address
    00:00:c5:c7:a0:74 that sends a local net broadcast with
    bogus sender address (XP's DHCP? Does anybody know?).

    The address 255.255.255.255 is the local link broadcast
    IP address, and it cannot be a legitime sender address.
