It is also tied to your pam configuration. PAM configurations with
pam_securetty will limit root logins to ttys listed in /etc/securetty.
As others mentioned, it is a *Bad Idea* to allow root logins via telnet
over the wire, secure network or not.
If you are looking for a way to be root on a remote machine, 'su' provides
you a minimal layer of protection, 'sudo' provides you a lot more, and
replacing telnet with ssh makes the security issue disappear entirely.
Replacing password logins with RSA/DSA key logins makes your system hard
as nails.
Do yourself a favor and disable telnet entirely and install ssh.
