I'd guess you'd want to make it a bit fancier though, to check whether the IP already exists, etc.
Hi Annihilannic,

I messed around yesterday and got this:

#!/bin/sh
set -x
B=1:
rm /home/banip/output.1
touch /home/banip/output.1

grep "Invalid user root" /var/log/messages|cut -c 68-79 > /home/banip/output.1

#If same entry is there more than 3 times

tmp1="`head -n 1 /home/banip/output.1`"
tmp2="`sed -n 2p /home/banip/output.1`"
tmp3="`sed -n 3p /home/banip/output.1`"

if [ $tmp1 == $tmp2 ] && [ $tmp1 == $tmp3 ]
then

A="`cat output.1| head -n 1`"

echo "$B""$A" >> /etc/config/ipsec_deny.conf
echo "$A is not banned"

I know its ugly and by far bulletproof - I will try to use your line and mess around. Always nice with inspiration Smilie

Thanks for your time much appreciated!
