FTP_service

A Terminal Based File Transfer Application

Server: ftserver.c

To Compile:

• make or make ftserver (using the makefile provided)
• gcc -g ftserver.c -o ftserver -lpthread (on the command line)
• compilall (to use provided bash shell script)

To Run:

• ftserver <port number> Server then runs indefinitely, servicing clients that connect until killed with SIGINT

To Remove Executable:

• make clean

Client: ftclient.py

To Run:

• [python3] ftclient.py <server> <server port> <command> [file name] [directory] [data port]

  • <server> is the host where the server is running,
  • <server port> is the port where it's expecting connections,
  • <data port> is the port where the server can send the requested document or directory.
  • The client can send 3 commands to the server: -l (list directory) -g (get file) or cd (change directory).

• so, more specifically:

  • ftclient.py <server> <server port> -l <data port>
  • ftclient.py <server> <server port> -g <file name> <data port>
  • ftclient.py <server> <server port> cd <directory>

Note: client will be prompted for username (admin) and password (password)... points for originality?

The program is able to transfer all kinds of files, tested up to 920 MB video file.

NOTES:

The programs run better (user experience-wise, not functionality) when they're in different directories, I created a folder for the client program and its transfers.

• Server is multithreaded
  • The server will create a new thread for each new connecting client
• Requires a username and password to access the server
  • user name: admin
  • password: password
• Client is able to change directories
• Program can handle various (all?) file types in addition to text.
  • tested with 920 MB .mp4 file, 88MB .Mv4 file, 8MB .pdf, 150KB aliceASCII.txt file, and 0MB .txt file
