[RndTbl] DNS Ubuntu

Did you create a zone entry in named.conf and the associated zone file?

zone "example.ca" {
 type master;
 file "example.ca.db";

  IN A

When you restart named, always look in the logs (/var/log/messages on most
systems) to see if any zones got turfed. If you make a mistake, named will
not load the zone, but will happily continue on with the next zone.

Does your forwarder work? eg can you nslookup cisco.com @localhost ? Is
named bound to all the interfaces?

BTW, if you're just trying to get example.ca working for development, the
fastest way is to edit your hosts file(s) and skip DNS entirely. DNS takes a
few "oops" moments to understand, and is often best skipped if possible.
