SSH-KEYSIGN(8)			   BSD System Manager's Manual			   SSH-KEYSIGN(8)

NAME
     ssh-keysign -- ssh helper program for hostbased authentication

SYNOPSIS
     ssh-keysign

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

     ssh-keysign is disabled by default and can only be enabled in the the global client configu-
     ration file /etc/ssh/ssh_config by setting HostbasedAuthentication 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 hostbased authentication.

FILES
     /etc/ssh/ssh_config
	     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 hostbased authentication is used.

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