You can configure listeners in ActiveTransfer Server. Each listener is associated with a host, port, and protocol. Clients can connect to ActiveTransfer Server through the configured listeners to transfer files and execute other commands, such as obtaining a directory listing. For example, if you create a listener with port 21 and FTP protocol, clients can connect to ActiveTransfer Server through port 21 by using any standard FTP client, and then transfer files or execute FTP commands.

You can create and manage any number of listeners on the Listeners page. Ensure that you select an ActiveTransfer Server or an ActiveTransfer Gateway instance before you start creating listeners. Each listener in ActiveTransfer Server awaits for a client connection to initiate file transfers.

You can add listeners to an ActiveTransfer Server or an ActiveTransfer Gateway instance by configuring basic settings, such as name, port, and protocol using the quick add feature that enables you to perform file transfers. To configure additional settings for listeners, see Configuring Advanced Settings for a Listener.
