SSH-KEYSIGN(8)          NetBSD 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 signature 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 configuration 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 authentica-
     tion.


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.
