Here is a shell script snippet that I use on my laptop. It gets called from make_resolv_conf() in /etc/dhclient-enter-hooks, where I make sure not to overwrite /etc/resolv.conf (it always points to localhost). Extracting nameserver addresses from resolv.conf is trivial, though. A prerequisite is that the "forwarders" clause in named.conf is on a single line by itself, for example: forwarders { 192.168.250.254; }; ----8<------------------------------------------------------------ LOGGER=echo named_conf=/etc/namedb/named.conf # Args: one or more nameserver IPs update_forwarders() { address_list= for nameserver in $* ; do test X$nameserver = X127.0.0.1 && continue # Stupid server... address_list="$address_list $nameserver;" done address_list="{ $address_list };" sed_command='/^options/,/^}/s/\([^#\/]*\)forwarders.*/\1forwarders' sed_command="$sed_command $address_list/" sed "$sed_command" $named_conf > $named_conf.dhcp if cmp -s $named_conf $named_conf.dhcp; then : else $LOGGER "New DNS servers: $*" if [ ! -f $named_conf.org ]; then cp $named_conf $named_conf.org fi cp $named_conf.dhcp $named_conf ndc reload fi return 0 } ----8<------------------------------------------------------------ It is more elegant in perl, but dhclient-enter-hooks is a shellscript, so it felt easier to just add it there. $.02, /Mikko To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-questions" in the body of the message
