Comcast: Changing ip's

[ronnie gauthier]

I dont see the problem. Set dhcp to expire every 24-48 hours. Whats the big deal with renewing if you keep the same IP, everything in from the outside will still be OK. Beat them to it and keep em happy, thy will never notice you then. I have charter not comcast and have never had a problem and I keep ports open most of the time. In fact charter hardly ever prokes around my ports. I renew every 2 days and have yet to get a different IP.

They said I had my computer set up to use a static ip number. They were
right. That is to say, my computer wouldn't reconfigure itself when the DHCP
server on the comcast end said to reconfigure. I have since rectified that
problem, but keeping dhcpcd running all the time is something I have to be
careful about. I may have to write a script which monitors dhcpcd and
restarts it or turns of my NIC if dhcpcd refuses to run.
DHCPCD is the only way I will have of knowing when they change
me. The problem was, they gave me an infinite lease last time and dhcpcd
turns itself off when the lease is infinite. I have written this script which
runs every time dhcpcd starts or, hopefully, detects a change in the ip
number assigned by comcast:

ifconfig eth1 down
echo "IP has changed" | mutt -s "IP CHANGED" jlh
/sbin/dhcpcd -d -h tow33dhcp1252.towson01.md.comcast.net eth1
 . /var/run/dhcpcd-eth1.info
/sbin/ifconfig eth1 down
/sbin/ifconfig eth1 $IPADDR netmask $NETMASK broadcast $BROADCAST
/sbin/route add -net default gw $GATEWAY eth1                           

This won't fix up my firewall or hosts.allow files, but I'll be working on
those in the near future! And, for all I know the route command won't work,
but I don't care as long as comcast doesn't cut me off.
