What's wrong about "adduser" ?

Remove that space after the comma!

If what you're asking is "Do I have to configure an account
to allow telnet logins?" the answer is no.  UID 0 is an
exception due to security concerns.

As the other replies already pointed out, superuser login via
telnet (apart from being bad in a big way for sending a root
passwort in cleartext over a potentially unsafe wire) needs to
connect to a pseudo-tty that has been set to "secure" in /etc/ttys.

What you really want to do is to use a secured connection.  Install
ssh(d) on the BSD machine and use a secure telnet client.  These are
available for a MacOS client machine as well.  Just take a look at

Get yourself a good book about unix administration ?
