Re: Network and serial port

Hey Bob, how are things in happy valley? Anyway, I've done what you're talking about
many times (for head-to-head linux Quaking!).  Here's whatcha do: I'll assume your
network uses the 192.168.1.0 network and your setup is this:

 BoxA (192.168.1.1)     BoxB (192.168.1.2)        BoxC (192.168.1.3)
       |-------- ethernet -------|    |------- serial ------|
                                   /dev/ttyS0           /dev/ttyS0

On BoxB run the following script:

#!/bin/bash
while true
do
    /usr/sbin/pppd /dev/ttyS0 115200 nodetach noauth proxyarp passive asyncmap 0
192.168.1.2:192.168.1.3
done

on BoxC run a similar script:

#!/bin/bash
while true
do
    /usr/sbin/pppd /dev/ttyS0 115200 nodetach noauth defaultroute asyncmap 0
192.168.1.3:192.168.1.2
done

(the pppd lines above are not supposed to be line-wrapped but I'm guess my naughty
mailer will do this)

That should do the trick.
