I'd rather not use named. tinydns seems simpler to set up (despite my
problems) and is theoretically far more secure.

What I have done is bind named to a dummy interface, which serves a
psuedo TLD, and use dnsmasq for the local DNS.


2: eth0:  mtu 1500 qdisc pfifo_fast
inet 10.111.1.130/24 brd 10.111.1.255 scope global eth0
3: dummy0:  mtu 1500 qdisc noqueue state
inet 172.17.211.1/24 brd 172.17.211.255 scope global dummy0

Then you have different interfaces to bind to, and different networks
to route to internally.

Well, tinydns must be bound to a different address than dnscache.

If I do a dig @ server1.linux.com it responds with
the correct address.

However, if I put the dnscache IP address in my /etc/resolv.conf,
resolution to *any* IP address (including server1.linux.com and
server2.linux.com) fails.

Thoughts?

What do you mean with "doesn't seem to work"? Timeout? Wrong answer?

I use dnsmasq as my home dns/dhcp server.  It was super easy to  
configure.  You might want to give it a look.

[gentoo-user] help with tinydns setup

[James]

All,

I'm trying to set up a DNS server here for a lab environment.

- hijacking a TLD (linux.com let's say, as an example)
- trying to point several Linux boxen in a sandbox with no internet connectivity

So, here's a copy of my tinydns data file:

.linux.com:172.18.109.125:a:259200
=server1.linux.com:14.17.108.241:86400
=server2.linux.com:14.17.108.242:86400

I've been following instructions on the following two pages in order
to get some guidance on where I'm going with this:

http://www.fredshack.com/docs/djbdns.html
http://wiki.vpslink.com/HOWTO:_Setup_a_DNS_server_with_tinydns

Inside of /etc/dnscache/root/servers/linux.com I have "127.0.0.1" so
that the server knows to query the tinydns daemon running.
Unfortunately, however, a "dig @ server1.linux.com" doesn't
seem to work.

Thoughts? Ideas?

Thanks!
