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

NAME
     sssshh-kkeeyyssiiggnn - ssh helper program for host-based authentication

SYNOPSIS
     sssshh-kkeeyyssiiggnn

DESCRIPTION
     sssshh-kkeeyyssiiggnn 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.

     sssshh-kkeeyyssiiggnn is disabled by default and can only be enabled in the global
     client configuration file /etc/sshconfig by setting EEnnaabblleeSSSSHHKKeeyyssiiggnn to
     ``yes''.

     sssshh-kkeeyyssiiggnn 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-
     tion.

FILES     /etc/sshconfig
             Controls whether sssshh-kkeeyyssiiggnn is enabled.

     /etc/sshhostdsakey, /etc/sshhostrsakey
             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, sssshh-kkeeyyssiiggnn must be set-uid root if
             host-based authentication is used.

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

     sssshh-kkeeyyssiiggnn first appeared in OpenBSD 3.2.
