 OpenSSH is a set of network connectivity tools used to provide secure access to remote machines. Additionally, TCP/IP connections can be tunneled or forwarded securely through SSH connections. OpenSSH encrypts all traffic to effectively eliminate eavesdropping, connection hijacking, and other network-level attacks.
 
-OpenSSH is maintained by the OpenBSD project and is installed by default in FreeBSD. It is compatible with both SSH version 1 and 2 protocols.

 When data is sent over the network in an unencrypted form, network sniffers anywhere in between the client and server can steal user/password information or data transferred during the session. OpenSSH offers a variety of authentication and encryption methods to prevent this from happening. More information about OpenSSH is available from http://www.openssh.com/[http://www.openssh.com/].

 SSH utilizes a key fingerprint system to verify the authenticity of the server when the client connects. When the user accepts the key's fingerprint by typing `yes` when connecting for the first time, a copy of the key is saved to [.filename]#.ssh/known_hosts# in the user's home directory. Future attempts to login are verified against the saved key and `ssh` will display an alert if the server's key does not match the saved key. If this occurs, the user should first verify why the key has changed before continuing with the connection.
 
-By default, recent versions of OpenSSH only accept SSHv2 connections. By default, the client will use version 2 if possible and will fall back to version 1 if the server does not support version 2. To force `ssh` to only use the specified protocol, include `-1` or `-2`. Additional options are described in man:ssh[1].

 Use man:scp[1] to securely copy a file to or from a remote machine. This example copies [.filename]#COPYRIGHT# on the remote system to a file of the same name in the current directory of the local system:
