Reminder of the second assignment, not due for a while yet.

You are to write a matched pair of programs, a server and client, to perform internet file transfers. It is acceptable to use all or any of the sample programs I provided (server.c, client.c), but don't expect to be able to make a few edits and have the assigment done effortlessly. This is not a very difficult assignment, but will take some time.

Requirements

• You should be able to start the server running on a computer and leave it unattended.
• The client should be capable of connecting to the server over the internet, and under user command retrieve a file from the server, or send a file to the server. Make sure that it doesn't only work for text files.
• To prevent unfriendly access to your files, it would be a good idea to require the client to send a password that the server verifies before accepting any transfer commands.

Things to remember

• To start a process running in the background, put an ampersand (&) at the very end of the command you use to start it.
• To make a running program survive you logging out, type nohup before the command that starts it.
• To stop a background process, enter the command kill -KILL processnum
• If you forget the server's process number (which is displayed whenever you start a program with an & at the end of the command line) use the ps command.
• If you forget the paramters required by a particular system function, don't waste hours looking for it in a book, enter the command man&nbps;
