I have a LAN with a Linux server running BIND for addressing of local computers. When a workstation is connected to the local network (where there is no Internet access), I can successfully address devices using hostnames without any problems:
$ host server1.local $ server1.local has address 192.168.2.2 $ host 192.168.2.2 $ 18.104.22.168.in-addr.arpa domain name pointer server1.local.
When that same workstation enables WiFi (or any secondary interface) and connects to the greater Internet, the machine can no longer address local devices by hostname. Presumably this is because it is using the wrong network interface's DNS server to address my devices.
My BIND configuration is as follows:
$ORIGIN local. $TTL 604800 @ IN SOA server1 admin ( 2008080101 ;serial 04800 ;refresh 86400 ;retry 2419200 ;expire 604800 ;negative cache TTL ) @ IN NS server1 @ IN A 192.168.2.2 server1 IN A 192.168.2.2 workstation1 IN A 192.168.2.44 workstation2 IN A 192.168.2.45
and the reverse DNS:
$ORIGIN 2.168.192.in-addr.arpa. $TTL 604800 @ IN SOA server1.local. admin.local. ( 2008080101 ;serial 604800 ;refresh 86400 ;retry 2419200 ;expire 604800 ;negative cache TTL ) NS server1.local. 2 IN PTR server1.local. 44 IN PTR workstation1.local. 45 IN PTR workstation2.local.
How can I force clients to look at the correct network interface to find hosts in the ".local" namespace? Is it possible to do this from the BIND-configuration end, since I may not have complete control over the individual clients?
