Re: [PLUG] Defaulting the domain for a name lookup

["K.S. Bhaskar via plug" <plug@lists.phillylinux.org>]

Fred –

The /etc/hosts technique does not scale well beyond a half dozen or so machines. We have a couple dozen. If we had to make the /etc/hosts trick work, we would probably set up a machine as the source of truth, with an alternate in case the main is down, and run a cron job to periodically copy that file. It' would be about the same level of effort as managing DHCP from the firewall.

Bhaskar,

If you're willing to look at alternate solutions (hacks), you can always
add a line to /etc/hosts containing the IPv4 address, FQDN, and short
name of the machine you're trying to connect to.  That bypasses the
entire DNS system.  Example line:

192.168.1.10    foo.mydomain.org       foo

Just a thought...
