DNRD - Domain Name Relay Daemon

What is DNRD?

DNRD is a proxy name server. To clients on your home network, it looks just like a name server. In reality, it forwards every DNS query to the "real" DNS server, and forwards responses back to the client.

So, why would you want to use it? DNRD was designed for home networks where you might want to dial into more than one ISP (ie, your home ISP and a dialup connection to your office). The problem with multiple dialups is that you need to change /etc/resolv.conf for each one. With DNRD, this is no longer necessary.

Your dialup machine will run DNRD (with appropriate options for forwarding messages to the desired DNS servers). All other machines on the home network, including the dialup machine itself, will use the dialup machine as its DNS server. Configuring DNRD is a simple matter of passing the correct command-line parameters.

I originally wrote DNRD to work with masqdialer. It works very well with masqdialer, but should also work with other dial-up systems.

Is there a mailing list?

Tomislav Filipcic was kind enough to create an i386 RPM for DNRD, including a source RPM.

Although a Makefile is included, you may wish to grab a copy of CONS in order to build it.
