Component parts of the OpenSSH protocol suite

The OpenSSH protocol suite comprises the following programs and commands:

• On the server side: Server program sshd (see "OpenSSH server daemon sshd")

• On the client side (see the interNet Services User Guide):

  • Client program ssh or slogin: replaces rlogin and telnet.

  • scp: replaces rcp.

  • sftp: replaces ftp.

• Administration utilities (see the interNet Services User Guide):

  • ssh-agent

  • ssh-add

  • ssh-keygen

  • ssh-keyscan

  To permit secure communication of Windows systems with BS2000 via SSH, the open source software PuTTY, for example, provides the functionality of the client side of OpenSSH.
