02 Jul computer networks simple homework
Three C programs have been posted above. (1) p3client.c is a TCP client, (2) p3server.c is a TCP server, and (3) forwarder.c is a combination of TCP client and server. Given forwarder.c is not working.
To compile the c programs, type “gcc –o p3client p3client.c”, “gcc –o p3server p3server.c”, and “gcc –o forwarder forwarder.c” in a terminal on Linux.
Modify “forwarder.c” as the following:
p3server must start first and wait for a forwarder. Write C codes to establish a connection to p3server. For this connection, you must use TCP client. (50 Points)
Once your forwarder is connected to p3server, a server in the forwarder will start (the related code was given). And then, p3client must start. If you type a word on p3client, p3client will send this word to the forwarder (the related code was given). Write C codes for the forwarder to send this word to p3server (50 points)
To run the programs on Linux, open three terminals, type ./server on the first terminal, ./forwarder on the second terminal and ./client on the third terminal.
Please see the detailed examples on “file 1” posted above
Do not modify p3client.c and p3server.c. The modified forwarder.c must be working with the given p3client.c and p3server.c
Submission: your forwarder.c
