102=item B<peer=>I<hostname>
103
104The other gateway providing forwarding.

107
108A public to install as authorized.

110=item B<tunnelip>
111
112True if the testbed uses the DETER tunnelip extension to provide external
113connectivity information

115=item B<use_file>
116
117If given read additional parameters from the file in
118/proj/I<project>/exp/I<experiment>/tmp/I<hostname>.gw/conf where those are the
119current testbed project and experiment and the hostname is before the first
120dot.  The file is option: value.

125=head1 SYNOPSIS
126
127B<prep_gateway.pl> laods the necessary kernel modules for low-level bridging
128configures the local sshd to allow it, restarts that sshd, and installs the
129given key in root's authorized keys.
130
131If the gateway supports DETER gateway, it setablishes outside connectivity and
132adds a host rout to the given peer.
