If eth0 is your connection to the internet then your this looks
like IP-spoofing or somebody on your eth0 segment is being attacked.

You can block it with activating the kernels IP-spoof protection
or with ipchains rules.

If you can find out the MAC of the attacker you can report him to
your ISP. Be friendly and say that the 'attacker' has mis-configurated
his computer, he wil get the message...

It is being logged every 4-5 minutes.

What does this mean? Please help?
