size or not by command : ls -al
>> Check files by command : diff sockit2me-2.5.tar.xz newarchivetar
>> ( should not get output , which means files are the same and the copy work fine )
>> Extract file sockit2me-2.5.tar.zx by command : tar -xvJf sockit2me-2.5.tar.zx

Unix Tools - Sockit , Python , C , Client , Server Programs [Video]

This is where the original code for the C programs in the sockit2me examples comes from. I had to update it a little bit, but the socket information discussed on this web page is still mostly correct. However, modern linux systems do not have the h_addr macro definition any more, so I had to adjust the code for that. Also, atoi() is not safe, so I had to replace that.

Lecture :
1. Download socket2me-2.0.tar.xz from dekdee.buu.ac.th/~mrham >> by links
       
        command >> links http://dekdee.buu.ac.th/~mrham

        >> then choose file socket2me-2.0.tar.xz >> ok

2. Extract it by tar >> tar xvJf sockit2me-2.0.tar.xz       ( xvJf >> .xz )
       
        go to directory sockit2me-2.0/
        comand >> make            to complie program
       
3. There are import file
        in C language >>
        client        with         server
       
        in phyton language >>
        client.py    with        server.py

4. How to send a message to server
       
        * open in 2 windows , one for client and other for server

        * to set name remcommand :
                command >> export PS1="myserver $"                on server windows
                command >> export PS1="myclient $"                on client windows
        * sending message from client to sever
            in C program :
                myserver$
                    command >> ./server 10008                10008 is port number
                    [waiting for client]
                myclient$
                    command >> ./client localhost 10008
                    Type your message : Hello server I am client 10008
                    I got your message
                myserver$
                    Hello server I am client 10008
                    mysever$
            in Phyton program :
                myserver$
                    command >> ./server.py 10008
                    [waiting for client]
                myclient$
                    command >> ./client localhost 10008
                    Type your messgae : Hello server I am client.py 10008
                    I got your message
                myserver$
                    Hello sever I am client.py 10008
                    myserver$
5. Look at source code the program

        phyton >> client.py & server.py
        C >> client.c & server.c
Download :
sockit2me-2.0.tar.xz
This archive contains simple client and server examples for TCP/IP stream sockets in C99 and python3.
