entries in /var/log/messages

Hi,

In /var/logs/messages I am getting repeat entries every 5-6 seconds that start


17 13:12:02 server kernel: ** IN_TCP DROP ** IN=eth0 OUT= MAC=00:0c:fi:80:30:fc


Should these be there ? what does it mean ?

Probably your firewall dropping packets from a port scan.. not too sure.
