Re: resolv.conf misbehaving

[Danny <dannydebont@gmail.com>]

Hi Guys,

Looks like it was a combination of a few things.

First of all (according to man "resolvconf") I had to add "dns-" hooks to
/etc/network/interfaces.

DHCP was also a little problem (like some of you pointed out).

"resolv.conf" now has both the router and Debian as nameservers automatically.

e can now do "dig fever.havannah.local" and it resolves correctly. It queries
the Debian (10.0.0.5) server by default, which I want.

However, if I do "dig -x 10.0.0.5" (the Debian server which is
fever.havannah.local) it fails to resolve simply because it queries the router
(10.0.0.2) instead of the Debian server which is 10.0.0.5. It is not even making
attempts to query the Debian server.

But if I force dig with "dig @10.0.0.5 -x 10.0.0.5" it resolves correctly.

Is it because 10.0.0.2 (router) is pushed into resolv.conf first?

Any pointers?

fever.havannah.local    =       10.0.0.5        =       Debian
router.havannah.local   =       10.0.0.2        =       router
