![]() The range for passive ports depends upon how many concurrent user clients you expect to have. Whatever the case, just open ports 20 and 21 for TCP connections and open a range of ports for passive FTP connections. Most of the Linux systems use ufw to manage firewalls, however, some cloud service providers like Microsoft Azure have firewalls outside of the Virtual machine and you have to configure that from their portal. If you do not use any firewall, you can skip this step. We need to open these ports from our firewall. Step 2: Configure FirewallįTP uses port 20 for active mode, port 21 for commands, and a range of ports for passive mode. The –now flag ensures that enable command affects our service immediately and not after a reboot. If your vsftpd is not active, then type in sudo systemctl enable -now vsftpd We can also use this command to enable and disable services on Linux. systemctl command is used to manage and check services on Linux. You can see under the Active heading that it’s active and running. Now we will check if the vsftpd service is active or not. There are two types of connection modes for transferring data: For transferring data, a data port is used. The client issues the command to the FTP server on port 21, which is the command port for FTP. A client makes two types of connection with the server, one for giving commands and one for transferring data. You can either upload a file to a server or download a file from the server. How does the FTP server work?įTP server facilitates the transfer of files between client and server. In this article, we will see how to set up an FTP server, configure user permissions, configure firewall and finally encrypt our FTP traffic with SSL. A client connects to the server with credentials and depending upon the permissions it has, it can either read files or upload files to the server as well. FTP server enables the functionality of transferring files between server and client. It is similar to other internet protocols like SMTP which is used for emails and HTTP which is used for websites.
