More and more internet access providers are closing port 25 to reduce spam except for connections to their own mailservers. If you run your own mailserver and have problems to connect to it on port 25, you can enable port 465 (smtps) in postfix as a workaround. Edit the /etc/postfix/master.cf file:
vi /etc/postfix/master.cf
and remove the # in front of the smtps line. Example for Debain 5, change the line:
#smtps inet n - - - - smtpd
to:
smtps inet n - - - - smtpd
and restart postfix:
/etc/init.d/postfix restart

Mo¿na zablokowaæ zdalny dostêp do systemu przez SSH. 1. open /etc/sshd_conifg in your favorite text editor.

replacing username1 and 2 with the short usernames of those users who *will* be able to log in via ssh. you can add as many as you want, separated by spaces.
