Description K2 2000-11-27 18:38:36 EST
Every minute I get message from kernel in messages log

Nov 28 00:30:45 <host> kernel: martian source fffff082 for f3c9f082, dev
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 07:38:54 EST
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
