The Linux Lab Robot
12 USD • Write two programs that will communicate through the internet sockets.One will act as a server, the other will be a client application.The server is a demon that is disabled from the control terminal after launch.The server program is required to run with one of two options:
-p port that makes the server work in the background mode, listening to client connections through the port on all available interfaces; only one copy of our server can work in the system at the same time, the attempt to reboot it must be signaled by the corresponding message;
-q, which will force it to check if the server copy is running at the moment in the system and, if it is true, it will be closed.Client (user program) is running with the mandatory four parameters -a addres_ip, -p port, -s string and -o operation, indicating to which server we want to connect and what the server should do for us.After connecting to the server, the client sends him string and operation to perform the operation.Accepted operations: tolower, toupperi invert.The server responds to the customer according to the request received by sending the modified line back (all letters have been reduced, all letters have been enlarged or the letters have been saved in the opposite order)
• After receiving the answer, the customer will display it and complete his work.• Considering the possibility of errors and responding to them accordingly (for example, trying to send a message to the client who has finished).Use the multiplexing mechanism on the server !!The !
