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

mosh-client

MOSH(1) 						      General Commands Manual							   MOSH(1)

NAME

       mosh-client - client-side helper for mosh

SYNOPSIS

       MOSH_KEY=KEY mosh-client IP PORT
       mosh-client -c

DESCRIPTION

       mosh-client is a helper program for the mosh(1) remote terminal application.

       mosh  itself  is a setup script that establishes an SSH connection, runs the server-side helper mosh-server, and collects the server's port
       number and session key.

       mosh then executes mosh-client with the server's IP address, port, and session key. mosh-client runs for the lifetime of the connection.

       The 22-byte base64 session key given by mosh-server is supplied in the MOSH_KEY environment variable. This represents  a  128-bit  AES  key
       that protects the integrity and confidentiality of the session.

       For constructing new setup wrappers for remote execution facilities other than SSH, it may be necessary to invoke mosh-client directly.

       With the -c option, mosh-client instead prints the number of colors of the terminal given by the TERM environment variable.

SEE ALSO

       mosh(1), mosh-server(1).
