I have a stand-alone computer with a PPP connection to my ISP and would
like to experiment with server programming.  Can I do this using
127.0.0.1 (localhost) as my server and client ?

I have some code that creates a ServerSocket and binds it to the
localhost on port 6001 and blocks on the accept method waiting for a
connection.  I have some other code which creates a Socket that attempts

to connect to port 6001 on localhost.  Unfortunately, the ServerSocket
doesn't appear to detect the connection (although the socket says that
it connects)

I guess the big question in this is can I do server programming with my
current setup or do I need a real server ?

I'm working on a linux box, with jdk1.1.7, by the way.

Thanks !

P.S.  Any suggestions on good networking programming books  ?
