Sparse files, such as the ones provided here via HTTP and FTP, can be created with something along the lines of: dd if=/dev/zero of=my_large_file bs=1 count=0 seek=10GĪnycasting is a technique where a single IP address is used in multiple locations in a network and packets are sent to the closest server. TCP windows have been slightly tweaked to support higher throughput. A small script called cleandir is used to clean the upload directory of the FTP server to avoid filling the file system with temporary uploaded files. Debian Linux is the operating system used, nginx for serving web pages and sparse files via HTTP and vsftpd is used for FTP. Each location consists of a 1U Supermicro server with an octacore Xeon E3-1240 V2 running at 3.4GHz, 32GB of RAM and an Intel 10GE NIC (82579LM chip). There are countless other uses, but FTP revolves around one thing: making it easier to manage and share files between computers.This page and the listed speedtest services are hosted on a number of servers spread through Europe (see locations). The family photo album is a basic example of how you could use an FTP server. Best of all, your family photo album is backed up, protected against any unforeseen issues. The FTP server doesn't restrict large file sizes, either, unless you specify. Your family photo album is then easier to manage and available to all of your family. A private FTP server (that requires a strong and unique password) provides a file hosting server that your family can access to download and upload family photo albums, all in one place. An FTP server allows you to organize your files as you would in a desktop file explorer, provide access to other users to download files remotely and set specific permissions as to what users can and cannot do to your files.įor example, you want to provide a permanent link for your family photo album online, but you also want to provide your family access to upload their photos. Do you need an FTP server? If you regularly send files to people, an FTP server might suit you. ![]() However, browsers generally offer fewer security options, so you should consider the FTP servers you access and the content you download. In this instance, the URL will look similar to you log in to the FTP server in your browser, you can access files similarly to an FTP client. Some FTP servers allow direct access with the inclusion of your username and password in the URL. When you enter the URL to access the FTP server, you'll have to enter your login credentials, such as a username or email address, and the password. The result will look something similar to this: The address will look slightly different to a regular website address, swapping out the for ftp://. FTP In the BrowserĪs mentioned above, you can use FTP from your browser. Furthermore, you can use the Windows File Explorer as an FTP client, accessing remote files as attached storage. There are several good free FTP clients available for Windows. That's a super simplified version of how IP addresses work- but can an IP address expose where you live? One of the most common examples is the Internet Protocol (IP), which dictates how data is delivered across the internet using IP addresses. The internet consists of numerous protocols, all of which define how the internet works. ![]() In the context of the internet and broader communications networks, a protocol is essentially a set of standardized rules that allow two or more entities to transmit and read information. The data channel is responsible for the transfer of data between the two computers. The control channel creates a connection between the two computers and establishes any credentials. How Does FTP Work?Īs a basic explanation, FTP uses two connections: a control channel and a data channel. It isn't the ideal method (an FTP client is preferred, more on these below), but it is functional.Īs an example, you can send and receive files from a Mac via FTP. Most modern web browsers can access an FTP server from the browser window if you have the correct address and login credentials. ![]()
