I have just enabled a resolving caching name server on my RH6 box and am
having difficulties understanding the concept of the search criteria found
in the resolv.conf file. This seems to be working correctly.
>From the DNS-HOWTO I am under the impression that for my domain name
(awa.com.au) I should be able to add entries into the hosts file for
local machines on the internal network.
host.conf is set : order hosts,bind
resolv.conf is set: search awa.com.au nameserver 127.0.0.1
nsswitch is set: hosts: files dns
hosts is set: 172.30.65.6 moose.awa.com.au
Under this configuration, the doco suggests that if I ping 'moose', then
resolv.conf would search for 'moose.awa.com.au', then ask dns for that
DNS would check the order via host.conf/nsswitch and first check the host
file and return the addr 172.30.65.6
What I actually see is DNS not checking the hosts file, but returning the
actual internet address of moose from our main nameserver.
Have I configured something wrong ? Do I have the basic procedure totally
In Short, What I am attempting to do is return the internal IP address of
our servers instead of the external addresses if the host name is configured
in the host file. I don't really want to set up a full blown DNS server if
I can help it.
