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.

Socket Send Specifies the total per-socket buffer space reserved for sends. This value is in bytes.
Socket Receive Specifies the total per-socket buffer space reserved for receives. This value is in bytes.
FTP Send The size of the send buffer used for reading file data and writing data to the network for unencrypted FTP transfers, in bytes
FTP Receive The size of the receive buffer for reading network data and writing data to files for unencrypted FTP transfers, in bytes.

PASV Port Range

These settings control passive FTP options.

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 Do not allow passive or active port requests below port 1024.

Windows NT

These settings are 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.
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.

HTTP/S Advanced Settings

These are advanced settings for controlling HTTP/S web client defaults for all users.

Temp Upload Directory HTTP/S web client uploads are stored in this directory as they are uploaded. When the upload completes, the file is moved to its final destination.

If this edit box is left blank, the temporary upload directory defaults to the temporary files directory for the account running the Cerberus FTP Server Windows Service for native accounts and LDAP accounts. For AD accounts, it defaults to the temporary folder for that AD user on the server machine.

This field can be used to override the defaults for all account types.
