Filter syslog
 

Hello

I wonder how i can filter the syslog ? ie there is a message that i dont want to se logged in there etc?

This depends on the syslog service you're using. I personally prefer syslog-ng which has various ways to do this which you can read about in it's standard documentation. More standard older syslog daemons don't really permit this, although rsyslog is very similar in terms of config to the normal syslog.conf but does provide more options.

i was loooking trough it and i dont quite understand. Can you give me an example in syslog-ng of how i filter(so it wont get logged) anyting that has a certain word/phrase in it ?

Here's an example for rsyslog:
which blocks out certain 'restorecond' messages. As you can see it's just a basic string match.
