SSH (Secure Shell) is an encrypted network protocol. It has many useful applications that solve all kinds of communication and security problems.

Secure Shell

The most obvious use for SSH is to allow remote machines to access a shell on the host computer. The host machine must be running an SSH Daemon (sshd) which usually runs on port 22. The remote machine must use an SSH client to connect to the host. On Unix based systems, the command "ssh hostname" will connect to the host specified by hostname with the same username as the user running the command. Alternatively, the user can type "ssh username@hostname" to log in as a different user. In either case, the user will usually be asked to enter the password for the specified user on the host.
