rsyslog server saves logs from remote also in /var/syslog

Question

I have setup my ubuntu server as syslog server to accept all my logs from my router and save them in a seperate mikrotik.log file in the /var/log/ folder.

Everything works but i notice that all messages are also copied in the /var/syslog logfiles.

Is there a way I can stop having these routermessages in my /var/syslog log?

Below are my config files for syslog:

/etc/rsyslog.d/10-mikrotik.conf

$template RouterLog, "/var/log/mikrotik.log"
:fromhost-ip, isequal,    "192.168.2.1" -?RouterLog
& stop

/etc/rsyslog.d/50-default.conf

Solution

Just before posting this question i changed :

/etc/rsyslog.d/mikrotik.conf

to:

/etc/rsyslog.d/10-mikrotik.conf

It did fix my problem then but i just discovered it now.

as I understand & ~ is deprecated and & stop should be used from v7 and up, so your suggestion does not help.

The config which was creating problem in this is case was /etc/rsyslog.d/50-default.conf on my ubuntu 14.04 with rsyslog 7.4.4. This file contains a ine to forward logs to /var/log/syslog. Adding a 10- in front of the mikrotik.conf in your case solved the problem because now it is opened before 50-default.conf and because you have added a line & stop in your 10-mikrotik.conf, it drops all the logs matching the defined criteria for further processing.
