Description K2 2000-11-27 23:38:36 UTC

Hi!
Every minute I get message from kernel in messages log

Nov 28 00:30:45 <host> kernel: martian source fffff082 for f3c9f082, dev
eth0
Nov 28 00:30:45 <host> kernel: ll header: 00 50 ba b5 de 6b 00 a0 24 1b ed
15 08 00

It appears even on start. What should it mean? My log become 200k more
every day

These problem is connected in some way with Samba, cause after I stop it the
messages dissaper

Comment 2 Arjan van de Ven 2000-11-28 12:38:54 UTC

You can disable the message by doing
echo 0 > /proc/sys/net/ipv4/conf/eth0/log_martians

you can also use Powertweak or sysctlconfig-gtk or add
"net/ipv4/conf/eth0/log_martians=0" to the /etc/sysctl.conf file 
to make this permanent.

This option stops the message about a "funny" packet being received by your
network card. ("martian" => funny enough to be from the planet Mars)

This can possibly be caused by a machine with a defective network card on
the network. This message in itself is harmless, but if you experience other
network problems as well, you (or your network admin) should find the defective 
card.
