FTP (file transfer protocol), is the standard protocol for moving computer files from a remote server to a client. It makes use of separate data and control connections. It is used often to transfer large files like videos from one machine to another. It is based on the client-server model.
Passive mode ftp server
Passive mode can be used by FTP servers and clients to bypass firewall filtering of incoming connections. Passive mode uses two random, unprivileged ports to allow data transfer between the client/server. Passive mode will be the default setting for WinSCP.
Active mode ftp server
An active mode FTP server differs from a passive one. In active mode, the client sends a port number to the server, and the server responds by connecting to it. In passive mode, the server opens a port and waits for a client to connect.
File transfer protocol (FTP).
The File Transfer Protocol server (FTP) can be used to transfer and store data between clients or servers. The protocol is a standard communication protocol used for transferring computer files. It uses separate data connections and control to transfer data to one end.
NATs
FTP servers with NATs can pose a challenge for many reasons. The routing devices should be able to interpret the protocol and modify the control connection dynamically. In order to maintain data connections, they must also keep state information. This ensures that packets arriving from an acceptable external address will transparently be rerouted to their internal server.
Firewalls
There are two basic types of firewalls. One on the server side and one in the client. The former is for servers running in private networks, while the latter is for servers on public networks. The main difference between these two is that the former denies all traffic except well-known ports. FTP clients cannot therefore connect to the servers.
Protocol client-server
FTP allows users to send and retrieve files from one computer. FTP comes in two main modes. There is an ASCII mode that allows text to be sent, which uses 8 bits per line, and a binary mode that allows images to be sent, which uses 36 bits per line. Both modes can either be specified in server settings or via an allow rule. ASCII mode is where the sending machine sends the file bit-by-bit and the recipient stores it when it receives it.
