At that time, the channels were not yet as fast as in the modern world, so a tool was needed for the reliable remote exchange of documents. This tool was the FTP protocol, which was distinguished by its simplicity and speed of work.<br \/>\nWe propose to study in detail the topic FTP-server: what it is, how it works, how to connect to it.<\/p>\n<h2><span style=\"font-weight: 400;\">What an FTP server looks like<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">What is an ftp server? <a href=\"https:\/\/unihost.com\/dedicated\/hosting-for-files\/\">FTP server<\/a> is one of the basic network file transfer protocols between PCs. Works over a local network and the Internet. This is the TOP technology for uploading and downloading information from remote servers.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4683 aligncenter\" src=\"https:\/\/unihost.com\/blog\/minio.php?2021\/11\/unnamed-1.png\" alt=\"ftp server\" width=\"550\" height=\"316\" \/ title=\"What is an FTP server and what is it for - Image 1\"><\/p>\n<p><span style=\"font-weight: 400;\">The external picture of the server depends on the system for the login. The well-known program FileZilla, in which data is entered through the file manager Total Commander. Most hosting sites have their own management system, which consists of a set of file folders.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since its inception, the <\/span><a href=\"https:\/\/unihost.com\/dedicated\/hosting-for-files\/\"><span style=\"font-weight: 400;\">ftp server<\/span><\/a><span style=\"font-weight: 400;\"> has changed significantly, although the basic essence is the same. There are now additional control commands as well as a separate data connection. The system allows you to perform two main operations: downloading and uploading files for storage. So, for example, when creating a web resource, all the information regarding the site is contained on the server and when you need to make some edits, change the settings, the developer goes to the ftp server, downloads the required file and, after the adjustments, uploads it back.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">FTP Server Features<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">What is ftp and what its main task is clear, but what about the technical aspects? The protocol works in a systematic way, in case of an error, the transfer process is stopped, the user is notified. If there were no errors, then the file was delivered with all the necessary elements. The protocol, in comparison with web servers, has a number of distinctive characteristics:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">all connections are made through different channels;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">access to ftp server only after authentication;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the presence of binary and text modes;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">multiple connection;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">can determine the type of file being transferred.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">It is the File Transfer Protocol that is considered the top one for remote data transfer.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How FTP-protocol works<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The server is necessary for fast operation and reliable transfer of information in file form via the Internet. Local networks can also be used. Due to the multiple connection, several channels can be used at the same time. So how does the ftp protocol work? We will try to describe this process in more detail.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Multiple connectivity implies the operation of multiple channels, thus increasing the speed and efficiency of the workflow. Management work takes place through one channel &#8211; commands and feedback, and with the help of others, files are transferred.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">There are two modes of server operation:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Active. The control connection sends an IP address. The port number on which the requested data will be received is also indicated. After receiving the information, the server makes a connection to the designated host. The session is activated and the transfer of documents starts.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Passive. It is used when the client is protected by a firewall with a firewall. With this option, it is impossible to accept the incoming connection, the PASV command is used for the IP address and the port number of the server itself.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Now it is clear how ftp works in two modes. But the exchange of information itself also takes place in several modes:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">streaming &#8211; data moves in a stream without protocol processing;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">block &#8211; the protocol divides data into blocks;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">compression mode &#8211; information is compressed.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">The client device is authenticated through the login and password, after checking for compliance, the server sends an invitation. But you can connect anonymously.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4689 aligncenter\" src=\"https:\/\/unihost.com\/blog\/minio.php?2021\/11\/unnamed-1-1.png\" alt=\"ftp\" width=\"647\" height=\"361\" \/ title=\"What is an FTP server and what is it for - Image 2\"><\/p>\n<h2><span style=\"font-weight: 400;\">Installing an FTP Server<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">To create an ftp server for storing files, you need specialized software. After the 6th version of the Windows operating system, Microsoft launched the IIS tool for sharing. It is thanks to Internet Information Services that a Windows-based <a href=\"https:\/\/unihost.com\/dedicated\/hosting-for-files\/\">FTP server<\/a> can be created. With this option, no third-party software is needed.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We suggest using the example of Windows 10 to figure out how the ftp server installation is going on. So, the order of actions:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In Control Panel, look for Programs and Features and Turn Windows features on or off.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the pop-up window, the &#8220;IIS&#8221; folder will appear, then the &#8220;FTP server&#8221; folder.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Check the &#8220;FTP Extensibility&#8221; and &#8220;FTP Service&#8221; checkboxes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the &#8220;Web Site Tools&#8221; folder, activate &#8220;IIS Management Console&#8221;, &#8220;FTP Management Service&#8221;.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Confirm all changes with the &#8220;OK&#8221; button. It will take some time for the server to start.<\/span><\/li>\n<\/ol>\n<h2><span style=\"font-weight: 400;\">Setting up an FTP server<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">If you successfully managed to create a ftp server, now you should proceed to the configuration stage. Using the same Windows 10 example, consider the step-by-step steps:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Find IIS Manager through the Administrative Tools section. Select &#8220;Add FTP Site&#8221; in the Sites folder. Next, set the name of the FTP protocol and the path to the data folder, confirm the actions.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Server parameters. An important point is entering the IP address, you can bind to a specific address or choose extended access to client devices.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Verify that port 21 is being used.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">If the server will operate in a permanent mode, check the &#8220;Start FTP site automatically&#8221; checkbox.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">In the &#8220;Authentication&#8221; section, you can configure access for registered or anonymous users.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The next step is to configure the operating system firewall. In the &#8220;Advanced Settings&#8221; section there is an item &#8220;Rules for Inbound Connections&#8221;, select &#8220;FTP Server (Inbound FTP Traffic)&#8221;.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">To connect visitors to the server, find the item &#8211; &#8220;Local users&#8221; and create a group with a name and description. Add users here.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Setting up a FTP server does not take much time, it is done quickly and easily.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">How to connect to FTP server<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">How to set up a <a href=\"https:\/\/unihost.com\/dedicated\/hosting-for-files\/\">FTP server<\/a> is clear, but how to connect? This can be done most conveniently using special programs. Let&#8217;s take a very famous application as an example. Almost everyone is familiar with Total Commander, which has the necessary functionality to connect the server.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Let&#8217;s say you need to add a new server. Selecting the Ctrl-F combination, run the &#8220;Connect to FTP server&#8221; item and add the following data:<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">the address;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">connection name;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">username and password;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">connection type.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">The connection is made in two ways: SSL &#8211; anonymous connection and TLS &#8211; using the secure FTPS protocol. FTP server provides access to all files stored on the server.<\/span><\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4693 aligncenter\" src=\"https:\/\/unihost.com\/blog\/minio.php?2021\/11\/unnamed-2.png\" alt=\"FTPS\" width=\"490\" height=\"341\" \/ title=\"What is an FTP server and what is it for - Image 3\"><\/p>\n<p><span style=\"font-weight: 400;\">Do not forget, if the password field is left blank, Total Commander will ask you for a password every time, which is not very convenient. But on the security side, it&#8217;s even better. With the correct settings, the connection will quickly be established and it will be possible to work with the information on the remote computer.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">What else is FTP used for<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">You already understood the main purpose, FTP is a server for transferring files. In addition to loading and unloading files, other file system commands are executed. You can store information of different volumes, both business and personal. Ftp server example of use &#8211; uploading photos, videos, creating catalogs. Using FTP, you can organize high-quality website administration and upload files to shared hosting. Almost all the information that a lot of people use every day is on FTP storage. This is software, and demo versions of programs, and e-books, in other words, everything that can be formatted into a file. Thanks to FTP, you can forget about the existence of disks and USB drives. Users from anywhere in the world can have access to the information they need.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Disadvantages of FTP servers<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Overall, FTP is a great server that is fast and guaranteed to deliver files to the user upon request. But there is an important drawback &#8211; weak protection against hacker attacks and hacks, so many do not risk storing confidential information. If someone connects to the local network or tries to intercept Internet traffic, then the data will be available for download. Another disadvantage concerns the security of the entrance. The File Transfer Protocol does not have protection against password guessing, which means that through trivial trials, someone can guess the password and gain access to the files. How to organize an ftp server so that there are no hacks? Make sure your computer is free of viruses. SSH is often used to encrypt username, password and data. By default, the exchange of data between the server and the client is in a completely open format. To avoid file theft, you can use FTPS. What it is? This is a protocol created to extend the basic version. With its help, a secure connection is established and all input commands and information are encrypted.<\/span><\/p>\n<h2><span style=\"font-weight: 400;\">Conclusion<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Let us summarize the information block in which you learned: what is File Transfer Protocol, what it is used for, how is the step-by-step creation of an FTP server, how to open an ftp server.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An FTP server is ideal for material sharing, cloud storage, and driver archives. It is quite easy to connect, there are methods for different OS, as well as the Total Commander program. We looked at the example of the Windows 10 operating system.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To understand the specifics of the server operation, you need to pay attention to the main features: connection through authentication, different channels for connection, several modes. The main, and perhaps the only, drawback of the FTP protocol is its security vulnerability. All information, including personal data for authentication, is transmitted unencrypted. The FTPS extension is used for the cipher.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Using an ftp server will greatly simplify your work, since today remote file management saves time, increases the efficiency of the workflow of companies and users.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You can use the services of the Unihost company by going to the site.
