The most annoying problem, Forgetting the root password which usually leaves with no choice but to totally format and reset your entire system or just coming to realization that your stuck with a brick server with limited functions. This walkthrough is focused on the DNS 323 , as I forgot the root password today and it was driving me mad trying to recover it so I could set up some usenet/torrent schedulers. Whats First?
First thing you want to identify is, Does your server have telnet enabled or disabled?
if you haven't disabled telnet it's as easy as jumping on telnet
typing
passwd
and changing your root password (DONE) there can be some differences with what setup your using but leave a comment and i'll try and help out

For the DNS 323 it was simply as downloading the fun-plug.tar , moving it into the main directory of my dns 323, restarting the server
On restarting , telnet with no password will be available which you can now login too

That's it, hope that helps some people out
