Configuring Bind

[laidlaws]

I am playing with OSGrid, and trying to get my computer to talk to itself via loopback. I have a NetComm router. From the OSGrid Wiki:

Connecting to your locally hosted server from behind a DSL router using NAT

Loopback Most DSL routers/modems prevent loopback connections as a security feature. This means that a NATed IP address ( such as 192.168.2.40 ) can not connect to your forward facing IP address ( such as 199.149.252.44 ) from behind your DSL router/modem. In a case like this, external IP addresses may connect to your server/region but you can not ( this applies to both standalone and grid modes ).

DNS solution(Linux) It's possible to host your own DNS-server, so you can prevent some of the dns-naming problems mentioned before. If http://example.org resolves to the external ip, and that loopback connection is prevented by your router, you could point your resolv.conf to a local nameserver like:

Code: Select all

nameserver 192.168.2.2

Now you need bind/named installed in order to handle the dns-requests. You can find a bind example configfile here.

(It isn't even a link )

At present I have installed bind with the default parameters. Is there a guide on what to do next? I assume that a caching nameserver is needed. The intention is to make the loopback happen locally, not in the router.

If you only want to resolve several hostnames, why not just add them to /etc/hosts and make sure that /etc/nsswitch.conf uses files first for hosts name resolution ?

Regarding named/bind setup, check e.g. https://wiki.mageia.org/en/Virtual_Mach ... t.2FVM_LAN for a few pointers ...
Or lookup a generic bind / named howto e.g https://wiki.archlinux.org/index.php/BIND or take a look at dnsmasq: https://wiki.archlinux.org/index.php/dnsmasq

Thanks Doktor. I want it as simple as possible, and I don't really need the extra speed from a local nameserver. I looked at a Ubuntu post, but Archlinux is very good for command-line stuff.

The problem arises when I put up the sim from my box then try to view it from a viewer on the same box. The IP address would be the same. I was thinking of logging in from my wife's laptop on the same network. That wouldn't be a loopback.
