Sorry to say that but nobody uses "telnet" nowadays. Telnet is a security hole by itself. Why don't you use ssh?

But to answer your question, you can create a new user and use "sudo" grant to him to execute any required command but "reboot".

When sudo is configured on you server (man sudo, man sudoers) you can telnet (or ssh) your server, login as the above user.

Hi.. problem is that box does not have ssh support.. so I have to go with telnet. – Ashwin Jan 16 '14 at 06:19
Does your box have sudo? The proposed solution also works with telnet. – HelpBox Jan 16 '14 at 09:48
