What is FTP (File Transfer Protocol)

FTP is a network protocol used to transmit files from one PC to another. FTP is a client-server protocol, meaning that a computer running an FTP server software is required to make files available for others to download. 

FTP is typically used to host website files, but can also be used to transfer large amounts of data between computers.

FTP uses a control connection to manage the transfer of data between two computers. An FTP client typically initiates the control connection and uses port 21. 

Once the control connection is established, the client can then request a file transfer over the data connection. The server typically initiates the data connection and uses port 20.

How to use FTP?

FTP

FTP (File Transfer Protocol) is a standard network protocol used to transfer files from one host to another. FTP is typically used to upload files from a user's computer to a server. 

FTP uses a client-server architecture, with a client program that runs on a user's local computer and a server program that runs on a remote host.

To use FTP, a user must have an FTP client program and a user account on the remote host. The user account must have been configured by the host administrator. 

When the user connects to the remote host, the FTP client program will prompt the user for a username and password. 

Once the user has been authenticated, the FTP client will display a list of the files and directories on the remote host. The user can then navigate the file system on the remote host and transfer files to and from the host.

Types of FTP

TYPES

There are two types of FTP: active and passive. Active FTP is the most common type and is used by most FTP clients. 

With active FTP, the client connects to the server on port 21 and then the server initiates a second connection back to the client on port 20. This is known as port forwarding" or "port mapping" and is used to allow data to be transferred between the two computers. 

Passive FTP is less common and is often used when active FTP is not possible. With passive FTP, the client connects to the server on port 21 and then the server listens for a connection from the client on port 20.

FTP security

FTP Security

FTP is a protocol that is used to transfer files between computers. It is a very popular protocol, but it is also very insecure. 

There are many ways to exploit an FTP server, and many attackers do so in order to gain access to sensitive information.

One of the most common attacks is known as a brute force attack. This is where an attacker tries to guess the username and password of an FTP account. 

If they are successful, they can then log in and download any files they want. Another common attack is known as a denial of service attack. 

This is where an attacker sends so much data to an FTP server that it becomes overloaded and can no longer function properly.

There are many ways to protect an FTP server from these kinds of attacks. One is to use a strong password. 

Another is to use a firewall to block incoming traffic from known attacker IP addresses. Finally, it is also a good idea to keep the server software up to date, as new security vulnerabilities are often discovered and patched.

What is an FTP server?

FTP server

An FTP server is a computer that stores files and makes them available to other computers on a network. FTP stands for File Transfer Protocol. 

When you connect to an FTP server, you can download files from the server or upload files to the server.

Conclusion:

File Transfer Protocol (FTP) is a method of transferring files between a local computer and a remote computer, using the File Transfer Protocol (FTP). The protocol was designed to allow users to interactively transfer files to and from remote computers but is also used to move large files (such as software or digital media) from one remote computer to another. Here at (our company), we use FTP to transfer files from our server to our clients.
