Ssh service is not enabled by default in Ubuntu system. This simple and brief tutorial will show you how to enable ssh service in Ubuntu.
First, launch a terminal window from the dash (or press Ctrl+Alt+T) for running commands.
Paste this command into terminal to hit enter to install openssh-server:
sudo apt-get install openssh-server
That’s it! Now you can use ssh client to connect to this host using the default port 22.
If you would like to change ssh settings, edit /etc/ssh/sshd_config file with your favorite editor. In this case I used the gedit:
sudo gedit /etc/ssh/sshd_config
After edited configuration file, save it and apply the change by restarting the ssh service:
sudo /etc/init.d/ssh restart
For a simple ssh client, download putty from here.
