FTP Server Configuration

For WHM version 11.38

(Home >> Service Configuration >> FTP Server Configuration)

This feature allows you to tailor your FTP server's behavior to your preferences.

For more information about your FTP server, see:

• ProFTPd documentation at http://www.proftpd.org/docs/.
• Pure-FTPd documentation at http://www.pureftpd.org/project/pure-ftpd/doc.
• Instructions for using the /etc/ftpusers file to deny FTP access for specific cPanel accounts.

To configure your ProFTP server:

1. Next to TLS Encryption Support, select whether you wish for TLS encryption for FTP connections to be Optional or Required.
2. Next to TLS Cipher Suite, enter the list, in standard format, of the TLS ciphers you wish for your FTP server to use.
   • For more information about TLS ciphers, see http://www.openssl.org/docs/apps/ciphers.html.
3. To Allow Anonymous Logins, select Yes or No.
   • Note: Setting this field to Yes could seriously compromise the security of your server.
4. Next to Maximum Idle Time (seconds), specify the number of seconds an FTP connection may remain idle before being disconnected by the server.
5. Next to Maximum Number of FTP Processes, enter the maximum number of active processes you wish to allow the FTP server to create. Since each connection creates a process, this will limit the total number of FTP connections.
   • Note: Entering none will disable limits on the number of FTP processes.
6. Click Save.

To configure your Pure-FTP server:

1. Next to TLS Encryption Support, select 1 of the following options:
   • Disabled — Disables TLS encryption.
   • Optional — Allows your users to specify whether they wish to use TLS encryption.
   • Required (Command) — Requires TLS encryption on all commands being issued to the FTP server. This will help to protect login and password information.
   • Required (Command/Data) — Requires TLS encryption on both commands being issued to the FTP server and data coming to and from the FTP server. This will protect both passwords and files being exchanged between client and server.
2. Next to TLS Cipher Suite, enter the list, in standard format, of the TLS ciphers you wish for your FTP server to use.
   • For more information about TLS ciphers, see http://www.openssl.org/docs/apps/ciphers.html.
3. To Allow Anonymous Logins, select Yes or No.
4. Select whether or not you wish to allow anonymous uploads. This will allow anonymous users to upload files to your FTP servers.
   • Note: Setting this field to Yes could seriously compromise the security of your server.
5. In the Maximum Load for Anonymous Downloads field. This will prevent anonymous users from downloading file from your FTP server in the event that the system's load average exceeds the average specified here.
6. Next to Maximum Idle Time (seconds), specify the number of seconds an FTP connection may remain idle before being disconnected by the server.
7. Specify the maximum number of FTP connections in the Maximum Connections field.
   • Remember: This limit is applied server-wide and not on a per user basis.
8. In the Maximum Connections Per IP Address field, specify the maximum number of FTP connections to accept from a single IP address.
9. Using the Allow Logins with Root Password pull-down menu, specify whether or not you wish to allow access to all of your FTP accounts using the root password.
10. Using the Broken Clients Compatibility pull-down menu, select whether your FTP server will ignore some protocol standards to improve compatibility with buggy FTP clients and firewalls.
11. Click Save.
