I want to login into my linux server through telnet but it is giving me errors. but I can login using any other user not root. how can I enable this?

1. First off you should NEVER telnet to another machine. Your password can be easily picked up off the network. Use ssh instead. It works just the same.
   You should also never directly login to a machine as root. You should login as a regular user and su to root. This will give you a bit of an audit trail in case something goes wrong.
   If you really must do what you ask (and I would NEVER recommend it) then edit /etc/default/login and comment out the line:
   CONSOLE=/dev/console
   (so it reads #CONSOLE=/dev/console)
   But really, don't do it…I cannot stress it enough…

3. I'm going to just repeat what's said above - SSH rather than Telnet. And SU or sudo if you don't find it too tedious, rather than logging in as root.

   Which distro is it? Some don't have a root user. (k)ubuntu, for example, to stop you doing this.
