Thanks Ranier,
The dhclient-script was the piece I was missing.
I made a few modifications if anyone is interested:
function update_static_routes () {
local action static_routes destination gateway
action=$1
static_routes="$2 " # add space for easy looping
while [ "$static_routes" ]; do
destination=${static_routes%% *}
static_routes=${static_routes#* }
gateway=${static_routes%% *}
static_routes=${static_routes#* }
route $action $destination gw $gateway
done
}
I added the following code twice:
# don't need to test old values for domain/host
# no problems if resetting them to identical value??
if [ x$new_nis_domain != x ]; then
echo $new_nis_domain >/etc/defaultdomain
nisdomainname `cat /etc/defaultdomain`
fi
if [ x$new_host_name != x ]; then
echo $new_host_name >/etc/hostname
hostname --file /etc/hostname
fi
# old and new static routes different?
if [ "x$old_static_routes" != "x$new_static_routes" ]; then
# delete old static routes if they existed
if [ "x$old_static_routes" != "x" ]; then
update_static_routes "del -net" "$old_static_routes"
fi
# add new static routes if they exist
if [ "x$new_static_routes" != "x" ]; then
update_static_routes "add -net" "$new_static_routes"
fi
fi
I'm sending a wishlist bug to extend the debian dhclient-script.
