An SSH connection can be established to the Linux shell using the service port.

# generated and included in configuration
# for SSHD to work.
# Keys should be stored in
#/etc/ssh/ssh_host_key
#/etc/ssh/ssh_host_rsa_key
#/etc/ssh/ssh_host_dsa_key
#
# You may do this by adding them to /mnt/os/extra-profile
# settings tar.gz file
#
# generate them on Linux using:
# ssh-keygen -q -t rsa1 -f /etc/ssh/ssh_host_key -C '' -N ''
# ssh-keygen -q -t rsa -f /etc/ssh/ssh_host_rsa_key -C '' -N ''
# ssh-keygen -q -t dsa -f /etc/ssh/ssh_host_dsa_key -C '' -N ''

# tar -C / -zcvf /mnt/os/extra-profile /etc/ssh/ssh_host_*
