Is possible to filter some kernel messages using syslog-ng?

Hi all.
I own a small server which set up several p2p vpns using openvpn.
Hosts aren't always connected, so i need to use the option "--ping-restart 60" on the server.
using an udp tunnel, tun devices are set up every minute, and every minute, i have this log messages:

Apr 13 15:11:32 Gozer kernel: tun0: Disabled Privacy Extensions
Apr 13 15:11:52 Gozer kernel: tun1: Disabled Privacy Extensions
Apr 13 15:12:01 Gozer kernel: tun2: Disabled Privacy Extensions
Apr 13 15:12:12 Gozer kernel: tun3: Disabled Privacy Extensions
Apr 13 15:12:54 Gozer kernel: tun4: Disabled Privacy Extensions
Apr 13 15:13:14 Gozer kernel: tun5: Disabled Privacy Extensions
Apr 13 15:13:32 Gozer kernel: tun6: Disabled Privacy Extensions
Apr 13 15:14:09 Gozer kernel: tun7: Disabled Privacy Extensions
Apr 13 15:14:17 Gozer kernel: tun8: Disabled Privacy Extensions

I understood this is not a critical error, but my logs are getting very fat over time.
I wonder if anyone knows if it is possible to configure syslogng to filter that messages.
in /etc/syslog-ng.conf there seems to be some logic to do it, but documentation is very cryptic.

...or maybe someone knows another way to disable those messages without recompiling the kernel.

thanks!

Yes this is possible. It's one of the basic functions of syslog-ng.

Rather than tell you how to do it, I'll point you to good docs. There's a syslog-ng guide you can download from balabit.com. Try http://www.balabit.com/dl/html/syslog-n … index.html.

There's also this: http://www.campin.net/syslog-ng/faq.html.
