Description:
Your task is to write client and server programs in C and in Java using UDP and TCP. You are required to do them on a UNIX based system.
Deliverables:
The server will receive a text string of up to 80 characters length. The server is expected
to run on one machine and wait for requests. Your client code will contact the server
using its host address (IP host or address and port number) and pass it a string. The server
will then change this string and send it back to the client. The client will display the
received string and exit.
Example
Assume that you started a server on machine machine1.ut.edu listening to port
number 32000. The syntax should look like the following:
-----------------------------------------------------------------------------
machine1> server 32000 <enter>
[Eventually, after the server responds, it should just
exit]
machine1>
-----------------------------------------------------------------------------
Then you ran a client on a machine (say machine2.ut.edu) using the following
arguments:
-----------------------------------------------------------------------------
machine2> client machine1.ut.edu 32000 <enter>
Enter text: This is my text to be changed by the
SERVER. <enter>
this.is.my.text.to.be.changed.by.the.server.
machine2>
-----------------------------------------------------------------------------
Important points:
•The client should send the string, wait for a response, print the response and then
exit.
•After sending the modified text string, the server should exit.
•The client should accept as input either a host name or an IP address and then the
port number.
•The client does not need to do any error checking, e.g. check to see if the host
name or IP address is valid, check to make sure the string is less than 80
characters, etc.
•If there are no upper case letters and no spaces, the server will return the exact
same string that is sent.
Your task is to write client and server programs in C and in Java using UDP and TCP.
You will end up writing (and turning in) 8 different programs:
1- Server in C using UDP (file name to turn in : server-c-udp.c)
2- Client in C using UDP ( file name to turn in : client-c-udp.c)
3- Server in C using TCP ( file name to turn in : server-c-tcp.c)
4- Client in C using TCP (file name to turn in : client-c-tcp.c)
5- Server in Java using UDP (file name to turn in : server_java_udp.java)
6- Client in Java using UDP (file name to turn in : client_java_udp.java)
7- Server in Java using TCP (file name to turn in : server_java_tcp.java)
8- Client in Java using TCP (file name to turn in : client_java_tcp.java)
Platform:
UNIX based system
Note: Apache server preferred.
