HI again Lutzer!
Probably it would work (and be worth my learning and doing) to add an
editing script to the last section of the initialization process during
boot. This should hold since the DHCP lease should be renewed if the
machine is on, and will handle any change if it is rebooted or turned
off/on. My basic idea is to use sed to parse and edit resolv.conf keying on
the modem's IP. My guess is that it will go into the /etc/rcS.d directorey
with a very high "s" number. I have done little of this sort of thing.
Lots of reading if by this method.
Before I do that I suppose I should look at "man dhclient" and "man
dhclient.conf" and see if there is a way to control dhclient's use of
The bad news is that I have other projects, and Monday I start a project
which will consume most of my time for about eleven days. I may not have it
for a couple of weeks to share and frankly it would be good to write on this
again if you still need it since I tend to get distracted.
May God Help Us!
