Assignment 8 -- Internet Programming Assignment

• Below you will find links to two binary programs, a chat server and a chat client. In the end, you should turn in a program that has the same functionality as the client. Do not start programming now (unless you want to).
• Step 1:
  • Download the programs and understand what they do.
  • To start the server, type ./chat_server <port>, where <port> is an integer greater than 1024
  • To connect to the sever, type ./chat_client <ip-addr> <port> <nick>
    • <ip-addr> is the IP-Address of the server host (use 127.0.0.1 if the server runs on the same host, use nslookup <name> for other hosts)
    • <port> is the same number as used for the server
    • <nick> is the nickname under which you will chat
  Caveats:
  • Due to firewalling, do not expect to be able to reach a server from outside the lab.
  • The binaries only run under Linux.
• I will try to keep a server running on lee on port 6666 for all of you to share.
• ./chat_client 172.19.0.2 6666 <nick> should connect to it.
• The programs. In Mozilla, right-click and choose "Safe link target as". You may (or may not) need to chmod ugo+x them after download.
  • The chat server.
  • The chat client.
