Description

ISL AlwaysOn - Desktop - Implement constant computer uid (FEATURE) [ISLALWAYSON-1715] More

Description

ISL AlwaysOn now supports constant Computer Unique Identifier (UID). This means that generation of UID is no longer a random string but is generated based on computer properties (motherboard serial/UUID, disk serial/id, hostname, etc.). The entropy of those computer properties is used to calculate a score that determines whether the UID should be recalculated. By default, only the generated UID, entropy score, virtual machine type, and computer model are sent to ISL Conference Proxy. To send and store all computer data to ISL Conference Proxy the "cuid_dump" customization should be set to "raw".

The constant UID feature is disabled by default and it can be enabled in the registry ("HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\ISL Online\ISL AlwaysOn\constant_uid" set to "true") or via customization (set the "ISL AlwaysOn constant uid generation" field to either "always" or "virtual"). It can be set up in a way so that a constant UID is generated either for all machines, or virtual machines only (Hyper-V, VMWare, Virtualbox, and Citrix Xen only, at the moment).

With the constant UID feature enabled, ISL AlwaysOn will switch to a different RPC for removing the connections - a list of connections that needs to be deleted is sent to ISL Conference Proxy. With the previous implementation, all valid connections are sent to the server that deletes the connections that are no longer valid.

The feature is especially useful in VDI environments where the virtual machine is always started from a master image. To prepare a master image the existing procedure should be followed (the "Master Computer Preparation" manual on the help pages) with the addition of the "constant_uid" field in the registry or customization as mentioned above.
