What is SSH and why use it?

SSH (Secure Shell) is a protocol used to establish a secure connection between two computers or servers. SSH is primarily used to manage files on a server via the command line.

With SSH, you can perform the following actions and more:

• Securely transfer data between server and client (using SFTP or SCP)
• Edit files directly on the server
• Use version control tools (CVS, SVN, Hg, Git)
• Use the Drush tool for Drupal users
• Access MySQL/PostgreSQL via command line
