This way zoneedit is only updated when ip changes.
Do I have script correct?
/etc/dhclient-exit-hooks.shwith this content
#!/bin/sh
# This script only gets called when dhclient runs

# Old and new ip address fields are populated by dhclient,

updater_prog = /usr/local/bin/wgetrest of command # my wget pgm
if [ x$old_ip_address != x$new_ip_address ]; # old not EQ new

Looks like that should work...

RE: Using dhclient to update zoneedit with my dynamic IP address
Thanks for the in-sight into the script code.
I could not get the /etc/dhclient-exit-hooks.sh to run at reboot.
After doing some research I found that dhclient-script
was checking for /etc/dhclient-exit-hooks.
Changed /etc/dhclient-exit-hooks.sh to /etc/dhclient-exit-hooks
and it worked.
Thanks again

RE: Using dhclient to update zoneedit with my dynamic IP address
Ceri Thanks for the pointer to the 'man dhclient-script'. I read through it 3-5 times and the best I can make out of what it says is, that if I create an file like this /etc/dhclient-exit-hooks.sh with this content #! /bin/sh wget -O - --http-user=username --http-passwd=password, 'http://dynamic.zoneedit.com/auth/dynamic.html?host=www.mydomain.com ' Then every time dhclient runs (IE: at bootup and lease expire) the dhclient-exit-hooks.sh gets run. I this the correct interpretation? My wget command does not need the ip address or even know that it changed, the event of running and making contact with the zoneedit site will give zoneedit the ip address value of the system requesting the http url request. I just need this to be launched at the correct time and dhclient is the correct facility and timing to do this. Any help would be greatly approached Joe -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Ceri Davies Sent: Friday, February 13, 2004 1:17 PM To: JJB Cc: [EMAIL PROTECTED] ORG Subject: Re: Using dhclient to update zoneedit with my dynamic IP address On Thu, Feb 12, 2004 at 05:32:42PM -0500, JJB wrote: The zonedeit FAQ says this command can be used in dhclient to update my dynamic ip address at zoneedit when ever dhclient gets an new IP lease from my ISP. wget -O - --http-user=username --http-passwd=password 'http://dynamic.zoneedit.com/auth/dynamic.html?host=www.mydomain.com ' Anybody doing this, or know what to add to /etc/dhclient.conf to make this happen Check the manpage for dhclient-script, specifically regarding the BOUND hook and /etc/dhclient-exit-hooks.

Yes.
As another example, my own script for a similar purpose:

updater_prog = /usr/local/bin/noip2
if [ x$reason = xREBOOT ] || \
[ x$old_ip_address = x ] || \
[ x$old_ip_address != x$new_ip_address ]; then
