Make an SSH Connection
In most cases, you can connect to your host and log in using your password without making any changes to the default settings. Use ssh to connect to the remote server. The syntax is:
ssh [options] [user@]hostname[#port] [remote_command [arguments] ...]
When no user is specified, the client connects using your current login name. When no port is specified, the client uses the default port (which is 22 unless this has been changed in the client configuration file).
When no command is specified, ssh creates a new session on the remote host. When a command is specified, the command is executed on the host and then ssh exits. When no user is specified, the current user name is used.
To open a terminal session to a remote server using defaults
Note: To simplify initial connections and eliminate the risk created by allowing users to accept unknown keys, administrators can manually add the host key to a user-specific or global known hosts list. For details, see Add a Key to the Client Known Hosts List.
