WP11468 and WP11473 completed, work on h1digivideo0-2
Work done by Patrick Thomas and Jonathan Hanks

WP11473 was completed.  We adjusted the network setup of the h1digivideo0-2 machines to match h1digivideo3.  Now all 4 systems are dual homed, with one interface on the workstation subnet and on the aux/camera network.  This allows for a simpler multicasting network setup (and matches LLOs setup better).  This is done as a preparation step for eventual replacing the core network switch in CDS (with a simpler multicast setup).

We updated the DNS to move h1digivideo[0-2] to the 10.22... network and added h1digivideo[0-3]-cam entries to reference the 10.106... network entries for the systems.

WP11468 was to reboot the h1digivideo0-2 machines.  We did this as part of our check that things where working after the network changes.  The idea was to restart the system to clear up some long running memory leaks.
