[plug] configuring ssh

[Gavin Corfield]

I'm setting up a debian server to act as a gateway.  I've got the basic
network up, I can ping both ways but I can't get ssh to work.  I have a
keys existing on my workstatin so I copied the identity_pub file across
from $HOME/.ssh/ on workstation to $HOME/.ssh/authorized_keys on the
server.  However I am unable to connect with ssh, I get:

ssh_exchange_identification: Connection closed by remote host

sshd_config is below:

# This is ssh server systemwide configuration file.
