that uses (network) sockets. The client-server application that you are to write is a server

that can run arbitrary shell command lines on the (remote) server machine and return the

output to the client. This lab is to be implemented in two separate files, to be named: (1)

lab4-server.c and (2) lab4-client.c. Each file must be able to be compiled into an

executable, which means they must contain a main, etc.

The server program should not take any command line arguments. When run, it is to

do the following: (1) create and set up a listening TCP socket　(2) go into an infinite loop

accepting connections from clients　(3) for each connection, follow the remsh application

protocol specified below, running each received shell command, and redirecting any output

from the commands back to the client. Continue accepting commands from the client until

the client closes the connection. The server
