Chapter 2: Setting Up a Linux Multifunction Server
Logging in Remotely
When you finish your installation, you should log into the server from a remote con-
sole on your desktop. We recommend you do further administration from another
system (even a laptop), because a secure server normally runs in what is called head-
less mode—that is, it has no monitor or keyboard. Get used to administering your
server like this, as if you were at a production site. On the remote machine you need
only an SSH client, which virtually all Linux distributions have and which can be
downloaded for other operating systems as well.
The following printout is typical of what you’ll encounter the first time you SSH to
your new Linux server:
$ ssh admin@server1.centralsoft.org
The authenticity of host 'server1.centralsoft.org (70.253.158.42)' can't
be established.
RSA key fingerprint is 9f:26:c7:cc:f2:f6:da:74:af:fe:15:16:97:4d:b3:e6.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'server1.centralsoft.org,70.253.158.42' (RSA)
