One of the best remote access tools in Linux is SSH, a protocol that allows remote command-line interfacing with a remote computer. When setting up a system like the VCR, where the screen may not necessarily be readable from across the room or (like many “Internet of Things” applications) may not have a screen at all, remote access to terminal is essential.
Ubuntu 14.04 does not enable SSH by default, but does provide easy access to the OpenSSH service via its software repositories. On the server machine (the one you wish to access remotely), run the following:
sudo apt-get install openssh-server
Once the packages are installed, you can change settings by editing the configuration file located at /etc/ssh/sshd_config in Nano (or other text editor).
Once your configuration settings are saved, restart the service to enable SSH access from your client computer:
sudo /etc/init.d/ssh restart
