Can't telnet anything

Suddenly telnet stopped functioning..

# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

Then whatever I input, nothing seems to respond. Please advice.

Re: Can't telnet anything

What's the output of 'sudo netstat -tupl'?

Re: Can't telnet anything

Seems to work here.  What if you try something like telnet archlinux.org 80 Then enter anything, followed by return.

You are trying to hit a smtp port.  Do you know whether the problem could lie there?

Re: Can't telnet anything

It was problem with upgrading dovecot2. I fixed postfix configs, that's why port 25 works now. But port 995 does not.

Re: Can't telnet anything

okay, removed dovecot altogether and using cyrus for sasl now. dovecot such as pain. Works fine now.
