By default, Novell® ZENworks® Handheld Management uses TCP/IP for communications between the ZENworks Handheld Management Access Point and ZENworks Handheld Management Server and between the handheld device and the ZENworks Handheld Management Access Point.
If you have just one ZENworks Handheld Management Access Point (installed as part of the ZENworks Handheld Management Server), there is no reason to turn on HTTP or SSL because the traffic between the ZENworks Handheld Management Access Point and the ZENworks Handheld Management Server is not going over the network. But you can enable HTTP and SSL for communication between handheld devices and the ZENworks Handheld Management Access Point.
If you configure SSL at the client and the server, additional encryption and verification is done on the data and the data source.
If you have installed the ZENworks Handheld Management Access Point on additional computers outside your firewall or if you have handheld devices connecting from outside a firewall, you might want to enable HTTP or SSL so that you do not need to open a port in the firewall or if you want all ZENworks Handheld Management communications to be encrypted.
If you enable HTTP at the ZENworks Handheld Management Server or ZENworks Handheld Management Access Point, these services listen to both TCP/IP and HTTP protocols.
SSL is supported on Palm OS devices running Palm OS 5.1 or later, and on Windows CE devices running Windows CE 3.0 or later. HPC 2.11 is not supported for SSL communication.
To use SSL communication in PPC 2000 devices, you must install the High Encryption pack for Pocket PC 1.0. You must reinstall the pack on every Hard-reset of the device. For more information about the High Encryption pack, see Microsoft’s High Encryption Pack for Pocket PC Web site.
