OpenSSH is the most widespread and de-facto standard implementation of SSH protocol. Both server and client tools are included.

OpenSSH is the most widespread and de-facto standard implementation of SSH protocol (Secure Shell). It is the default SSH toolset for most *nix systems. The OpenSSH is open source licensed under BSD license.

The OpenSSH suite includes:

  • sshd - SSH deamon
  • sftp-server - SFTP server subsystem (though in current versions of OpenSSH, the SFTP server is built into the sshd. The sftp-server binary is kept for a backwards compatibility)
  • ssh - SSH terminal client
  • sftp - SFTP client
  • scp - SCP client (internally it works as SCP server too)

Other tools included are ssh-add, ssh-agent, ssh-keysign, ssh-keyscan, ssh-keygen and ssh-keysign.

The OpenSSH server (the sshd) is configured using sshd_config files. The client tools are configured using ssh_config file.
