B<combo_active.pl> - Do both the active configuration of a connectiveity gateway and service port forwarding.

=head1 OPTIONS

=over 8

=item B<fedkit=>I<install_dir>

Directory in which this software is installed.  Generally not needed.

=item B<interfaces=>I<interface table>

A list of interfaces to forward data on of the form:

=begin text

iface ip_addr

=end text

The interface is the operating system name of the interface and the IP address
is given in standard dotted decimal notation.  Other characters on a line are
ignored.

=item B<peer=>I<hostname>

The other gateway providing forwarding.

=item B<perl=>I<perl_binary>
 
Location of the perl binary.  Usually unneeded.

=item B<port=>I<port_spec>

Forward the given port.  The port is specified as 
for B<port_forward.pl>

=item B<ssh=>I<ssh_binary>

The pathname of the ssh binary.  Unusally unnecessary.

=item B<ssh_pubkey=>I<keyfile>

A public to install as authorized.

=item B<ssh_privkey=>I<identity_file>

The identity to use for remote access

=item B<tunnelip>

True if the testbed uses the DETER tunnelip extension to provide external
connectivity information

=back

=head1 SYNOPSIS

Call B<active_config.pl> and B<port_forward.pl> with the relevant parameters.
