Overview<\/h2>\n

The FTP Server Configuration<\/em> interface allows you to customize your chosen FTP server\u2019s behavior.<\/p>\n

\n
Note:<\/div>\n
\n
    \n
  • \n

    This interface is only<\/strong> available when you enable FTP services on your server. For more information, read our Service Manager<\/em> documentation.<\/p>\n<\/li>\n

  • \n

    We support Transport Layer Security (TLS) protocol version 1.2.<\/p>\n

      \n
    • We strongly recommend that you enable TLSv1.2<\/code> on your server.<\/li>\n
    • You can use RFC4346 or TLSv1.2 to manage your Pure-FTPd server.<\/li>\n<\/ul>\n<\/li>\n<\/ul><\/div>\n<\/div>\n

      How to configure your ProFTPD server<\/h2>\n

      To configure your ProFTPD server, perform the following steps:<\/p>\n

        \n
      1. \n

        From the TLS Encryption Support<\/em> menu, select a setting for TLS encryption of FTP connections:<\/p>\n

          \n
        • \n

          Optional<\/em> \u2014 FTP users choose whether to use TLS encryption. This setting offers the best compatibility.<\/p>\n<\/li>\n

        • \n

          Required<\/em> \u2014 Requires TLS encryption on commands that users issue to the FTP server and on data that comes through the FTP server. This setting protects all traffic from eavesdroppers.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

        • \n

          In the TLS Options<\/em> text box, enter NoSessionReuseRequired<\/code>. This is the default setting. This setting softens the requirement to reuse the SSL session for data connections from the control connection.<\/p>\n<\/li>\n

        • \n

          In the TLS Cipher Suite<\/em> text box, enter the list, in standard format, of the TLS ciphers that you wish your FTP server to use.<\/p>\n

            \n
          • \n

            This setting defaults to HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3<\/code>.<\/p>\n<\/li>\n

          • \n

            Typically, you should only adjust this setting for PCI Compliance.<\/p>\n<\/li>\n

          • \n

            For more information about TLS ciphers, read OpenSSL\u2019s Cipher documentation.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

          • \n

            In the TLS Protocol<\/em> text box, enter the TLSProtocol directive that ProFTPD will use when it establishes SSL\/TLS sessions.<\/p>\n

              \n
            • \n

              This setting defaults to SSLv23<\/code>. This setting allows the SSLv3<\/code> and TLSv1<\/code> protocols.<\/p>\n<\/li>\n

            • \n

              You should only adjust this setting for PCI Compliance.<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

            • \n

              From the Allow Anonymous Logins<\/em> menu, select whether users can log in to your FTP server anonymously. <\/p>\n

              \n
              Warning:<\/div>\n
              \n We do not<\/strong> recommend that you enable anonymous FTP, because it dangerously<\/strong> compromises the security of your server.\n <\/div>\n<\/div>\n<\/li>\n
            • \n

              In the Maximum Idle Time (seconds)<\/em> text box, enter the number of seconds that an FTP connection may remain idle before the server disconnects it.<\/p>\n<\/li>\n

            • \n

              In the Maximum Number of FTP Processes<\/em> text box, enter the maximum number of active processes the FTP server may create. Because each connection creates a process, this setting limits the total number of FTP connections.<\/p>\n

              \n
              Note:<\/div>\n
              \n To disable limits on the number of FTP processes, enter none<\/em>.\n <\/div>\n<\/div>\n<\/li>\n
            • \n

              From the Show Symlinks<\/em> menu, select whether you want ProFTPD to display symbolic links (symlinks) as such, and not as files or directories. The default for this setting is Yes<\/em>. For more information about symlinks, visit Wikipedia\u2019s Symbolic link entry.<\/p>\n<\/li>\n

            • \n

              From the Symlink Compatibility<\/em> menu, select whether you want to allow some FTP clients to display the correct symlinks to directories. The default for this setting is No<\/em>. If you choose Yes<\/em>, you must also enable the Show Symlinks<\/em> setting.<\/p>\n<\/li>\n

            • \n

              From the TCP Wrappers<\/em> menu, select whether you would like ProFTPD to use the TCP Wrappers package. With this package, you can configure the \/etc\/hosts.allow<\/code> and \/etc\/hosts.deny<\/code> files. For more information on how to edit these files, read our ProFTPD Configuration for Host Access Control documentation. The default for this setting is No<\/em>. <\/p>\n

              \n
              Important:<\/div>\n
              \n

              CentOS 8 removed support for the TCP Wrappers package (tcp_wrappers<\/code>). This change means that ProFTPD does not<\/strong> use TCP-Wrappers-based access controls on AlmaLinux 8, CentOS 8, and CloudLinux\u2122 8 systems. The rest of ProFTPD\u2019s functionality still works in those operating systems. ProFTPD\u2019s functionality in cPanel & WHM version 94 on CentOS 6 and 7, CloudLinux 6 and 7, and Red Hat\u00ae Enterprise Linux\u00ae 7 systems continues to use TCP-Wrappers-based access controls.<\/p>\n<\/p><\/div>\n<\/div>\n<\/li>\n
