The Network Device

When the krpc kernel module is loaded, it also creates a network device, rpc0. This lets you run IP over the RPC radio, similar to a wireless Ethernet card in ``peer-to-peer'' mode. All IP protocols (e.g. TCP, UDP, ICMP) work as usual--just a lot slower. In fact, the interface is so slow and unreliable that it is not especially useful for interactive applications such as telnet or X terminals. However, it may be useful for sending occasional debug or control information.

The rpc0 network interface is used just like any other interface. For example:

   ifconfig rpc0 192.168.1.1 (on one machine)
   ifconfig rpc0 192.168.1.2 (on a second machine)

The two hosts should then be able to ping each other, telnet to each other, etc.
