Create a drop-off directory within your Computer Science home directory by typing the following commands:
Like in homework 4, you'll create either a client or server. The networked application is simple. A server accepts connections from two clients. When a client first connects it receives the message:
This message is always followed by a Java end-of-line. Note that this same message is sent even if the connecting client is the second client to make the connection.
After both clients have made a connection, the server transmits:
where hostname is the name of the computer running the other connection. In the case, different message are sent to the two clients.
Then both clients transmit a three-character string followed by a Java end-olf-line.
The server responds the six-character string formed by concatenating the two three-character strings sent by the clients.
This assignment must be written in Java.
This is a 20 point assignment that can be completed at different levels. Your completed assignment should be stored in the directory ~/csci/343/home07 that you created above.
You write the client program. This program will be a minor modification of the example Java client shown in class.
You write a sequential server application, one that can handle only one pair of connections at a time. Start with the example Java server discussed in class.
Do more that the B-level. You can write a concurrent server, you can write a server with logs, or you can do something imaginative.
You can do this assignment at any level in groups of up to three people provided each of you keep a diary as discussed in Homework 4
You are not allowed to show (or email) your code to someone who is not a member of your group without the explicit permission of the instructor. You are also not allowed to review the code of others without their explicit permission.
A server is running at port 2362, that's 1999 + 363, on enka.cs.unca.edu that you may use to test your client.
This assignment is due at 12:00 noon on Friday, 10 December. No late assignments will be accepted because grades are due the following day.
