To determine error recovery and detection, we unplugged the two test computers from the Shunra Storm and connected them to a 100-Mbps hub. We started a remote-control session and a file-transfer session for each program and unplugged the host from the hub. We did this three times for each product and averaged the three tests.
To test whether these applications encrypted the authentication and data stream to prevent clear text from passing on the wire, we used WildPackets EtherPeek NX 1.0.0 to capture and analyze all packets transferred between guests and hosts while connected to a 100-Mbps hub. For the Novell, Spartacom Technologies and uRoam products, we added the server into our packet-capture sequences.
Finally, we looked at the memory usage on hosts to determine the cost of remote control on corporate desktops and servers. We were careful to compare apples with apples in the memory requirements. For both Altiris and Novell ZENworks, we included the base client footprint and the remote control applications. Other components of the packages were not included in the calculation. Memory usage was measured while the programs were in memory and dormant (no remote-control session active) and active in a remote-control session.
