    1313Get a linux laptop with a serial port.  Connect the Soekris serial port to it using a crossover serial cable.  There are a lot of these, unused, floating around ORBIT.  They have "X OVER" written on them.

    15 Run minicom in a terminal window that can handle vt102 (any of them can).  The first time you start a console, minicom should be set for 19200 baud, 8 databits, no parity, 1 stop bit, no flow control.  Be sure to turn hardware and software flow control off in minicom.  The UNIX device for talking to the console is almost certainly /dev/ttyS0 or /dev/ttyUSB0.  Usually when linux runs its console on a serial port, it goes at 9600 baud, so set the console baud to 9600 (see below) when you have the chance.

    1717Minicom and the Soekris console driver seem a little fragile.  If you do wind up dumping junk to the serial port (as will be the case if you run pppd carelessly), you may gum it up so badly that you need to reboot.

    161 5. Change iptables and the routing table in the Soekris net4801 so that the traffic coming in over ppp0 goes to the right interface on the ORBIT node, and so that all traffic from the ORBIT node's interfaces goes to ppp0.
     1615. Configure the Soekris net4801 as a router (echo 1 >> ip_forward) over ppp0.

    163 6. Change iptables, the routing table, and multi-homed interfaces in the landing so that packets for the remote ORBIT nodes are routed on the rest of the ORBIT network.
    164 
    165 7. Install and configure dhcp proxy on the host.
    166 
    167 8. Try L2TP instead of SSH for tunneling.  We don't care about encryption, particularly.
    168 
    169 8. Re-engineer voyage so it can be installed fifty times.
    170 
    171 9. Think about using a bigger CF card and making the net4801 a caching proxy for tftp.
