Basic Syntax

The tool on Linux for connecting to a remote system using SSH is called, unsurprisingly, ssh.
The most basic form of the command is:
  • ssh remote_host
The remote_host in this example is the IP address or domain name that you are trying to connect to.
This command assumes that your username on the remote system is the same as your username on your local system.
If your username is different on the remote system, you can specify it by using this syntax:
  • ssh remote_username@remote_host

Later, we will cover how to generate keys to use instead of passwords.
