Telnet Vs Rlogin

[Vadivelu Elumalai]

I have used both rlogin and telnet to access a remote machine. But
I don't know when to use telnet and when to use rlogin. I know that
rlogin uses the ~/.rhosts and involves more set up than telnet.

Is it possible to rlogin a machine, which could be accessed by telnet
and vice-versa? I think it should be possible, because most of the
machines have reserved ports for both.

Could someone elicit the main differences between these two?

Thanks.
Vadi.
