SSH is one of the feature remote access program on ubuntu. It is make easier our job in access set of Equipment. Here I assume install ssh on the mail server using Ubuntu Linux and later we will remote mail server using putty from windows machine. The following step by step setup SSH on ubuntu :

root@server:~# aptitude update && aptitude install ssh

Edit file sshd_config at folder /etc/ssh/sshd_config

# change port 22 with port 888 ( can used with other port )
# change PermitRootLogin yes with change PermitRootLogin no

– save by pressing :wq and Enter –

Then restart SSH

root@server:~# /etc/init.d/ssh restart
