If you need anything else (configuration file), post reply. I would show you.
Thank you very much. I am a newbie. Not good english. Please explain clearly.

0) If the port uses SSL then you don't want to telnet as you can't do a SSL handshake. Instead use something like

Code:

true | openssl s_client -connect localhost:465

1) If a port seems "closed" when it should be open always check: a) tcp_wrappers (/etc/hosts.{allow,deny}), b) iptables-save output, c) system and daemon logs in /var/log/ and d) the daemon configuration for clues.
