The goal of this project is to create a FTP server. We must implement a specific protocol defined by Epitech to communicate with the client.
./myftp port path

EPITECH MyFTP Protocol (RFC959 Extract)
You MUST have an "Anonymous" account with an empty password
Each bonus MUST be RFC959 compliant
The following are the mandatory FTP commands from client to server:
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
Command-Reply Sequences (Mandatory part)
The server reply is defined to contain the 3-digit code, followed by Space , followed by one line of text, and terminated by the Telnet end-of-line code .
