OBJECTIVE The objective of this lab is to leam basics of client/server programming with sockets and gain a deeper understanding of the transport layer protocols such as UDP and TCP. A simple UDP application will be developed to demonstrate the communications between a client process and a server process. BACKGROUND Socket opens a "door" between the application process and the transport layer protocol. By using sockets, two (or more) processes running on different machines can communicate and exchange data. The original Berkeley sockets application programming interface (API) was included in the 4.1 BSD Unix operating system (released in 1981) and comprised a library for developing applications in the C programming language that perform inter-process communication, most commonly for communications across a computer network. Nowadays, many programming languages such as Java and Python all provide socket programming LAB ACTIVITIES: 1. For this lab, make sure you login to the Linux system of the lab computer 2. Skip this step if you are a C programmer. Read carefully the attached source code UDPClient,java and UDPServer.java for a client and a server based on user datagram protocol (UDP). These programs lustrate how two processes can communicate using datagram sockets. The source code TCPClient.java and TCPServer java are a client program and a server problem based on transport control protocol (TCP). These programs illustrate how two processes can communicate using TCP sockets Test and run the server and dient programs as follows. Start a terminal and comple the Java program UDPClient.java using the command javac UDPClient.java. Do the same compling for other Java files. Then run the sever class on your own host java udpServer Then, start an ssh session to remote login to any of the machines in ITD415, using the command ssh username hostname, where hostname can be any of the following hostnames: id415m01.cs.unb.ca id415m02.cs.unb. ca id415m50.cs.unb.ca Run the client class on the remote host, and follow the prompt to enter a short message to send to the server (xx should be the number of your local machine): java udpClient id415mxx.cs.unb.ca
