Getting Started
Download CS365_Lab14.zip and unzip it.
You can import it into Eclipse, or unzip on the command line.
Building from the command line:
ant
Running from the command line:
./run.sh Server port
Your Task
Implement a server that
- listens on a TCP port and accepts connections
- reads a single line of text from each connection
- parses the received text to extract two integer values
- computes the sum of the integer values
- sends a single line of text containing the sum back to the client
- closes the connection socket
You can use the socket example programs from Lecture 16 as a reference.
Hints
You can implement this server as a “one shot” protocol” where the server reads a single request, sends back a single response, and then closes the connection.
If you have additional time, you can consider adding the following features:
- Allow the client to submit multiple requests, one per line, and have the server send back as many responses as necessary
- Use threads to allow multiple clients to connect simultaneously
Testing
You can use the telnet program to test the server. For example, if the server is listening on port 10001, then run the command
telnet localhost 10001
to connect to the server. You can type a line of text containing the two numbers to be added. You should see a response containing their sum.
