Achieving Persistence in VDI Blaster Systems
Once you have installed the VDI Blaster software, for all intents and purposes,
your system has been converted into a terminal and now possesses virtually all
of the same attributes and behaviors one would expect from a typical terminal.
Your system now runs in a stateless, non-persistent mode. This means any
connections or system settings configured in the Control Panel will be
discarded on reboot unless the terminal is being remotely managed by an Echo
Thin Client Management server. More specifically, a profile must be created
AND applied to these newly converted thin client terminals to maintain
persistent settings across multiple system reboots.
The VDI Blaster terminals run a service, called the Echo Agent, which
communicates back and forth with the Echo server. When a terminal is booted,
the Echo Agent will announce its presence to the Echo server by continuously
sending XML-based messages known as heartbeats. By default, the agent will
be sending these messages out to a server named ws-broker . You can change
the Server Address to another IP in the Control Panel by clicking
Management .
Once the agent heartbeats into the server for the first time, the discovery process
begins and varied information about that device will be displayed in a new row
in the Terminals table in Echo. The default name of the device will be set to a
unique identifier, consisting of 32 alphanumeric characters. The terminal's IP
Address and MAC Address are also reported in this row. The best method for
identifying newly discovered terminals is to match these two addresses with the
IP and MAC addresses reported on the terminal's Interface Status screen.
