Enabling FTP-SFTP Conversion (Windows)

On Windows, the connection capture component required for the FTP-SFTP conversion feature has to be separately selected during installation. For installation instructions, see Installing on Windows .

On Windows, FTP-SFTP conversion is automatically active when the Connection Broker is running and the filter rules enable FTP-SFTP conversion in the Connection Broker configuration. You can make filter rules to define additional settings for FTP-SFTP conversion.

The following example configuration converts any FTP connections to port 21 on any host to SFTP. The user name and the destination host name are taken from the application that initiates the connection.

In addition, if the target SFTP server is configured to send a banner to the client, the Connection Broker can forward the SFTP server banner to the FTP client if the Send SFTP server banner to the FTP client check box is selected.

If a connection profile is used in the FTP-SFTP conversion, you must create a filter rule that specifies the used connection profile, and to make sure that the Send SFTP server banner to the FTP client check box is selected in the rule.


Make sure that you have selected the Show server banner check box either on the General → Default Connection page's Server tab, or in the used connection profile if the default settings are not used.

Sending SFTP server banner to the FTP client will cause an extra connection opening to the target SFTP server for retrieving the banner message.

In case of a failure in retrieving the banner message from the target SFTP server, the banner that Connection Broker forwards to the FTP client includes an error description, a default banner, and the following text:

Can't fetch banner from SFTP Server
