Opening a SSH session to a remote machine
The SSH command line to open a session to a remote machine is called ssh.
The syntax is:
ssh remote_machine_ip/hostname
In this case, you will open a SSH session using your currently logged in user as a user for the remote machine,
the SSH command will interpret the command to:
ssh your_current_logged_in_user@hostname
Example:
[root@geek-kb ~]# whoami
