Example text

Unfortunately, the entire authorization scheme relies on the IP address of the source machine, which can be spoofed, particularly on an unsecure network. The most secure way to use SSH is to use password-protected public/private Rivest, Shamir, and Adleman (RSA) or Digital Signature Algorithm (DSA) key pairs. Access to any given account is granted only to users who not only possess the private key file, but also know the passphrase used to decrypt that file. Another component of SSH is a program called ood)]cant.

You can use an empty passphrase, or you can use the ood)]cajp command as discussed in the next section. One major disadvantage of empty passphrases is that they are easy to guess, even by people with little skill. SHOULD YOU USE AN EMPTY PASSPHRASE? Some think that using an empty passphrase is one of the seven deadly sins of system administration. We think it can be appropriate within an isolated environment, especially when the security implications are minimal. For example, a Beowulf cluster generally has an internal private network containing only one machine with an external network connection.

This prevents a specific key from forwarding any ports over its connection. jk)T--)bkns]n`ejc6 SSH can also forward X11 connections over the encrypted connection, allowing you (and the nkkp user) to run X11 applications that display on the computer initiating the SSH connection. The jk)T--)bkns]n`ejc command disables this feature for the key in question. jk)]cajp)bkns]n`ejc: This prevents an ood)]cajp connection from being forwarded to the host when a user connects to it with the specified key.
