Install SSH Server on Ubuntu 14.04

In order to install SSH server on Ubuntu, you need to install OpenSSH server package. Use the following command to setup SSH server:

sudo apt-get install openssh-server

Configure SSH Server

After installation is done, edit the /etc/ssh/sshd_config file. Take the backup first by typing:

sudo cp -a /etc/ssh/sshd_config /etc/ssh/sshd_config_backup

Now edit the file using command:

sudo nano /etc/ssh/sshd_config

Edit the following

# ports, IPs and protocols
Port 2122

Now for more security edit the following:

Set PermitRootLogin to no so that there is no root login allowed

# Authentication:
LoginGraceTime 120
PermitRootLogin no

Now allow users to access the system remotely by adding to sshd_config file at the end of the file by writing following command:

AllowUsers user1 user2

Replace user1 and user2 with your actual usernames.

Now restart the service by typing:

sudo service ssh restart

Finally ssh server is installed on Ubuntu.
