Bridging with SSH Tunnels
Here is the scenario:
I use an OpenBSD 2.9 box as my firewall and gateway at the house. One of the boxes behind my OpenBSD box is my FreeBSDBox.
I would like to be able to use port forwarding with SSH to enable a secure connection from work to the OpenBSD box and to have the OpenBSD box foward via SSH to the FreeBSD so that I can use VNC from work to access the FreeBSDBox via the OpenBSD box.
Has anybody in the forum used multiple SSH tunnels across a gateway to accomplish this?
This is not any serious, just something to occupy my otherwise dull and drab life.

ssh-keysign
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 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 authen-
tication.
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, read-
able 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.

ssh-keysign first appeared in OpenBSD 3.2.
