I have noticed that I am getting loads of these messages in my syslog

Code:

Jan 21 07:22:19 polaris martian source 81.174.224.71 from 81.174.224.69, on dev eth1
Jan 21 07:22:19 polaris ll header: 00:09:5b:1f:16:42:06:05:5d:9f:a3:74:08:00

They all come within my IP range with a couple of exceptions, should I be worried about these?

Hi,

here is a nice description:
http://sourceforge.net/docman/display_doc.php?docid=1445&group_id=13751

You can turn off logging

Code:

echo 0 > /proc/sys/net/ipv4/conf/(all|default|eth0|eth1)/log_martians

Regards,
