Dns

I would like to set up a DNS on my system, just to learn really, how difficult and what all is involved in the set up? How difficult?

Hello!!!
Please give us OS you want to install DNS. You can see pre-compiled binary for DNS-Bind from http://www.isc.org/index.pl?/sw/bind/
You can also download source and just go through simple README. In short you need to do it run "configure" then "make" and "make install". Then read man pages. Also you can refer Bind HOW-To

running mandriva

well, you should search for an "rpm" package for your Linux.

rpm?.........

Is not really so dificult , you may even have DNS server installed on your server , only have to start the bind daemon. ( use nmap , to see if port 53 for DNS server is open ).

DNS , is not hard to set .Default settings are just very good for a begginer , but if you want to set up zones , and other thing's , you have much more to work.

For rpm's try yum command ( not sure working under Mandriva , works under Fedora ..)
