You end up in a command line on the computer, logged in as one of the users there.įurthermore, we don’t need a PC to connect, even a smartphone can be used. The result of a connection is always identical. However, the remote computer must have a running SSH server, otherwise, we won’t be able to connect it using command or SSH client from our local computer.Īs soon as we have established a connection, a prompt will happen to enter the password of the remote PC user to get logged in and access the same in completely encrypted form. The idea behind using SSH is to establish a secure connection with another computer in the network. Hence, to use SSH on Ubuntu or any other system port 22 must be allowed in the system firewall. It works on a dedicated port number that is 22. SSH, or Secure Shell, means both a network protocol and the software required for its usage.
