     ssh-keysign - ssh helper program for host-based authentication


     ssh-keysign is used by ssh(1) to access the local host keys and generate
     the digital signature required during host-based authentication with SSH
     protocol version 2.

     ssh-keysign is disabled by default and can only be enabled in the global
     client configuration file /etc/ssh/ssh_config by setting EnableSSHKeysign
     to ``yes''.

     ssh-keysign is not intended to be invoked by the user, but from ssh(1).
     See ssh(1) and sshd(8) for more information about host-based authentica-

	     Controls whether ssh-keysign is enabled.

     /etc/ssh/ssh_host_dsa_key, /etc/ssh/ssh_host_rsa_key
	     These files contain the private parts of the host keys used to
	     generate the digital signature.  They should be owned by root,
	     readable only by root, and not accessible to others.  Since they
	     are readable only by root, ssh-keysign must be set-uid root if
	     host-based authentication is used.

     ssh(1), ssh-keygen(1), ssh_config(5), sshd(8)

     ssh-keysign first appeared in OpenBSD 3.2.
