Shell Script to Block the IP addresses

Hi All,

I have created shell script to block the IP addresses in 4 servers.
============================================================
#!/bin/sh
LOG=/home/logs/ip.log

. /home/server.conf

for n in ${HOSTS}
do
ssh -q -A -i /home/.ssh/id_home $n "/sbin/iptables -I INPUT -s $LOG -j DROP"
done
============================================================

Where
vi /home/server.conf (contain all the 4 host server IP addresses)
HOSTS="10.40.11.1 10.40.11.2 10.40.11.3 10.40.11.4"

LOG=/home/logs/ip.log contain all 2 IP addresses that I needs to block in iptables of above 4 servers
say-
11.22.33.44
11.22.33.55

Thanks,
