[SOLVED] telnet localhost without port failed

[yanny]

Is it normal that it fails when I type:


telnet localhost


Because when I type telnet localhost 25 I can connect to localhost.localdomain.

Yes, that is normal. port 25 is used for email (SMTP). Telnet uses port 23. You must have telnetd running if you want to be able to telnet to your machine.

To the OP:
Telnet is bad, use SSH instead. Telnet sends passwords in clear text.

Ok, thanks!

So telnet to localhost is not neccessary at all?

I don't see why you would want to open a telnet session to the local host when you could just open a terminal, so yes i would say telnet isn't needed, nor would SSH be needed unless you wanted to remotely access that machine from another.
