Full Discussion: Need help about read() and write() on TCP/IP
Top Forums Programming Need help about read() and write() on TCP/IP Post 302469557 by Loic Domaigne on Sunday 7th of November 2010 01:49:29 AM

Is it a homework? In this case, post in the Homework forum...

You first need to define a protocol between your server and your client (on top of TCP), so that both understand the command "server is busy update", "select beer", "light/black", "select quantity", "liter/bottle"

On the client side:
- The client connects to the server.
- The client reads the answer from the server. Note that you will have to implement a timeout on the read().
- The client sends back answer to the server as appropriate.

On the server side:
- the server accepts the connection
- the server sends reply to the client
- the server reads reply from the client
The implementation of the "server busy update" is tricky: you'll have to fork (or create a new thread) upon each connection. Only one client can be served at a time; the other children/threads should take care of the "busy update".

HTH,
Loïc

bup-server

bup-server(1)						      General Commands Manual						     bup-server(1)

NAME

       bup-server - the server side of the bup client-server relationship

SYNOPSIS

       bup server

DESCRIPTION

       bup server  is  the  server  side of a remote bup session.  If you use bup-split(1) or bup-save(1) with the -r option, they will ssh to the
       remote server and run bup server to receive the transmitted objects.

       There is normally no reason to run bup server yourself.

MODES

       smart  In this mode, the server checks each incoming object against the idx files in its repository.  If  any  object  already  exists,	it
	      tells  the  client  about  the  idx file it was found in, allowing the client to download that idx and avoid sending duplicate data.
	      This is bup-server's default mode.

       dumb   In this mode, the server will not check its local index before writing an object.  To avoid writing duplicate  objects,  the  server
	      will tell the client to download all of its .idx files at the start of the session.  This mode is useful on low powered server hard-
	      ware (ie router/slow NAS).

FILES

       $BUP_DIR/bup-dumb-server
	      Activate dumb server mode, as discussed above.  This file is not created by default in new repositories.
