Logging to the screen

Logging to the screen

[Scott Mayo]

I just noticed that my fireall is sending some of my LOGs to the screen. 
  I had tried setting something up a while back to LOG certain things, 
and was not sure if it was working or not.  Today, I went to the actual 
firewall itself and see all this info that I had my IPTABLES log, on the 
screen.  Any reason why it is not sending it to the /var/log/messages?
Thanks.

The answer is in your LOG rules (--log-level) and syslog.conf(5). LOG 
uses syslog(2) facility "kern" and priority as set in --log-level 
(default is probably "info".)

Thanks for the info.  I got to reading the man pages on syslog.  My 
iptables were logging with the value 'debug'.  From what I read, if I 
understand this correctly, that will cause syslog to send the message to 
the screen.  I changed my iptables to a log-level of 'info' and it is 
now sending the messages to /var/log/messages.

Thanks again.

Yikes, debug level to the screen? Normally it should only be serious 
messages going to the screen. My syslog.conf has *.emerg only to 
console.

NP.

It should be sending to syslog via klogd, if you have that properly
set up. To keep it from logging to the console, set sysctl
kernel.printk to something like 2 4 1 7
