this gives details of the network programming

This is a simple rpc-based 2-way talk program (2-way chat). 
rpcgen isn't much help with this (as far as code generation), as we
need a custom server and client within the same program. rpcgen is used
to create xdr filters and a header file...

This is old code, written in the days when sockets was the native
network API on Suns. Now sun RPC is based on TLI, so to get this to
work you need to do a few things:

1. include the compatability library librpcsoc - this is in
/usr/ucblib. The Makefile is already set up with this...

2. put up with a bunch of warning messages (or clean things up
to get rid of them).

3. To run on a sun you need librpcsoc and must have
/usr/ucblib in LD_LIBRARY_PATH (your environment variable).

Start the first talker with "rpctalk"

start the second one with "rpctalk hostname", where hostname is the host
running the first talker. Both can be the same host...
