FTP Server (my_ftp)

• binary name: myftp
• language: C
• compilation: via Makefile (all, clean, fclean, re)

Description

The goal of this project is to create a FTP server. I implemented request sequences that are explained in the protocol (more information could be find in RFC959). The network communication is achieved through the use of TCP sockets.

Server

USAGE: ./myftp port path
    port is the port number on which the server socket listens
    path is the path to the home directory for the Anonymous user

The server is able to handle several clients at the same time by using select for command management and fork for data transfer

The server has an authentication with an Anonymous account and an empty password. Data transfers uses active or passive mode.

Client

You can use any ftp client. I also made one that you can use... cd src/client && make or make at root.

Commands

USER <SP> <username> <CRLF>   : Specify user for authentication
PASS <SP> <password> <CRLF>   : Specify password for authentication

CWD  <SP> <pathname> <CRLF>   : Change working directory
CDUP <CRLF>                   : Change working directory to parent directory

QUIT <CRLF>                   : Disconnection

DELE <SP> <pathname> <CRLF>   : Delete file on the server

PWD  <CRLF>                   : Print working directory

PASV <CRLF>                   : Enable "passive" mode for data transfer

PORT <SP> <host-port> <CRLF>  : Enable "active" mode for data transfer


HELP [<SP> <string>] <CRLF>   : List available commands

NOOP <CRLF>                   : Do nothing

(the following are commands using data transfer )

RETR <SP> <pathname> <CRLF>   : Download file from server to client
STOR <SP> <pathname> <CRLF>   : Upload file from client to server
LIST [<SP> <pathname>] <CRLF> : List files in the current working directory
