    I have messages like (on a centos 3.8 box)

NET: 21 messages suppressed.
martian source from, on dev eth0

on my screen.  In the same time it is being logged to a file.
Are there any way to stop the logging of these messages on the console 
and still logged to a file (/var/log/messages)

Thank you.
