iptables output?
6 answers - 853 bytes -

I have configured iptables on my server, and now now I get output going
to my text windows (in the GUI, do a ctrl+alt+F1 to get to one of them).
This text pops up whenever a packet of some type is intercepted. These
packets also seem to be logged, as logwatch reports on them. The problem
is, I can't do any work from these text windows, because the 2+line long
strings overwrite what I am working on. This is very annoying.
Can anyone tell me how to redirect this output to /dev/null or someplace
else?
This is a sample:
Invalid packet: IN=eth0 UT=
SRC=10.1.4.238
DST=224.0.0.1 LEN=36 TS=0x00 PREC=0x00 TTL=225 ID=5592 PRT=ICMP
TYPE=9 CDE=0
(I transcribed this from the terminal window, so it may not be exact,
but you should get the idea)
Any ideas?
Thanks!

Check your /etc/syslog.conf
You probably have a line that says: kern.*/dev/console
and maybe *.emerg*
Look at your /etc/sysconfig/iptables file.
you probably have a LG target (-j LG)
you can set on that line in /etc/sysconfig/iptables
I think those things are what you are looking for.

The line in /etc/syslog.conf is commented out, so it appears that
/dev/console is the default (man syslog.conf doesn't seem to say).
Does anyone know if sending non critical errors to /dev/null harm anything?
kern.info;kern.!err /dev/null
Thanks,

Why not just send them to a file? better yet, don't log broadcast
messages from IPTables.

I tried creating a log for the output by altering the /etc/syslog.conf
file. I changed :
#kern.* /dev/console
to
kern.* /var/log/iptables
This put the output into /var/log/iptables, but the output is STILL
going to /dev/console as well. Notice that the appropriate line in
syslog.conf was commented out initially.
I don't know how to stop the output going to /dev/console except for
stopping the logging of iptables output.
Anyone know what might be wrong?
