Fall 2003 CSCI 363 Exercises

Unless otherwise indicated all exercises are due at noon on the day indicated. Because a shell script will be run to collect the solution, you must have your program in place by 11:00 am of the due date.

Exercise 1 -- Due 5 September

Modify the client program of section 1.4.2 of the textbook to open a TCP connection to port 3630 of etowah.cs.unca.edu and send a single line containing your name and your student id. You should do this assignment by yourself. [I assume you would not share your student id with another.]

Use the following lines to create a read-protected directory in your UNCA CSCI account.

 [user@mach dir] mkdir -p ~/csci/363/exer01
 [user@mach dir] chmod 700 ~/csci/363

Store your completed program in ~/csci/363/exer01/solution. You may write your program in C, C++, Java, or Perl.

Log of connections

• Connections logged by the Perl based server

Exercise 2 -- Due 3 October

Write TCP client program that performs the following actions.

• Connects to port 3630 of etowah.cs.unca.edu.
• Reads a line of input from the server. That line will contain from 37 to 73 characters and will be terminated by the string "\r\n".
• Counts the number of times the character '#' occurs within the input line.
• Writes a line of output to the server. That line should contain the '#'-count encoded as an ASCII string and followed by the line terminator string "\r\n".
• Reads a line of input from the server. That line will contain YES if the count was correct and NO is it was not.
• Closes the socket connection.

Store your completed solution in your UNCA CSCI account in one of the following files depending on the programming language you use.

Exercise 3 -- Due 21 November, 11:00 am

See the Exercise 3 page. You can also download my test programs for the assignment. It is written in Perl and will acquire some tweaking to get it to work.

Exercise 4 -- Due 3 December, 11:00 am
