How to stop console alerts?

Hi,

If I login to the console and doing something and the firewall blocks someone I seem to get the alerts come up on the console.

Is there something I can do to stop these alerts appearing?

Thanks

I came here looking for the same answer. What I'm seeing is that while any user is SSH'd in, even a normal user, they see random console messages like:

Message from syslogd@host at Feb 22 18:34:05 ...
kernel:nf_ct_ftp: dropping packetIN= OUT=eth0 SRC=1.2.3.4 DST=5.6.7.8 LEN=65 TOS=0x10 PREC=0x00 TTL=64 ID=5761 DF PROTO=TCP SPT=21 DPT=48357 SEQ=305140503 ACK=1229315770 WINDOW=14600 RES=0x00 ACK PSH FIN URGP=0 OPT (0101050A4945DEB94945DEBA)

Normal users should not see that kind of thing. Any ideas on preventing it would be appreciated.

This specific message is produced by the kernel, not the csf configured iptables, and it broadcasts it at the (r)syslog *.emerg level. If you don't want to see it you'll need to reconfigure (r)syslog on your system.
