Configuring Advanced Settings

The advanced settings page contains options for passive mode, running as a Windows Service, network buffers, and power management.

Send and Receive Buffers

These settings control the size of the buffers used for data transfers. Cerberus will read and write packets of this size for send and receive operations.

• Send - Number of bytes to send at once.
• Receive - Number of bytes to receive at once.

PASV Port Range

Controls passive FTP settings.

• Start - First port in the port range to use for passive connections.
• End - Last port to use for passive connections before wrapping back around to the Start port.
• Deny FXP Transfers - File eXchange Protocol (FXP) is a method of data transfer which uses the FTP protocol to transfer data from one remote server to another (inter-server) without routing this data through the client's connection. Conventional FTP involves a single server and a single client; all data transmission is done between these two. In the FXP session, a client maintains a standard FTP connection to two servers, and can direct either server to connect to the other to initiate a data transfer.
• Deny Reserved Ports - Don't allow passive or active port requests below port 1024.

Windows NT

Settings only available on Windows NT and higher.

• Install as a Windows Service - If enabled, installs Cerberus FTP Server as a Windows Service. After selecting this option and pressing "Ok" to close the Server Manager the user may be prompted for an account with permissions to add a service to the system.
  • IMPORTANT: Remote access using SOAP must be enabled for the administrator to be able to access the GUI when running as a Windows Service. If you haven't already enabled Remote access then selecting Install as Windows Service will automatically enable it and prompt you for a remote access password.
• Use optimized file sending - Uses the built-in Windows API for fast file sending.

Operating System

Controls how the server responds to certain operating system events..

• Respond to power management events - If enabled, Cerberus will attempt to gracefully shutdown and startup in response to power suspend and resume events. May allow more graceful recovery from suspending and resuming the system.
• Shutdown Server when Windows is shutting down - Detects operating system shutdown or restarts and tries to gracefully terminate all connections and ensure all server settings are saved.
