I use variables in my firewall script. For my IP address, I use the
variable "IPADDR", and I define it at the beginning on the script as :
IPADDR="`ifconfig eth0 | grep inet| cut -d : -f 2 | cut -d \ -f
1`" . That way I don't have to go through the entire script and change it
every time my IP address changes. I also run the firewall script out of
cronttab every 1/2 hr to pick up any changes.
