first remove 172.17.20.17 from the listen-on list,
best remove the whole listen-on statement ...
then copy named.conf to /etc/named.conf and verify
that "/usr/sbin/named" will start a bunch of processes
with "pidof named" which should show something like
15788 15787 15786 15785 15784
if this works, you could start named with the
following line on the root server (if not
try the minimalistic config file below):
# chbind --ip 172.17.19.1 /usr/sbin/named
you should now be able to connect from e.g.
172.17.19.2 to 172.17.19.1:53, verify that
with dig or nslookup on _another_ host
# dig www.13thfloor.at @172.17.19.1
if this works (and it should), you can change
to the usual vserver scripts (v_named) and
configure the address in /etc/vservices ...
some minimalistic named.conf file could be ...
# cat /etc/named.conf
options {
directory "/var/named/";
pid-file "/var/run/named/named.pid";
auth-nxdomain yes;
forward first;
forwarders { 212.16.32.2; 212.16.32.101; };
};
best,
Herbert
