Proxy:  Chapter 5

If you check “Permit screen blanking on connect,” you will allow a Proxy Master
to optionally blank the screen (set it to black) during a connection. If you
uncheck this field, then you will always be able to see the screen during a
connection, even if the Proxy Master has requested screen blanking.

Local Security Settings

A set of three checkboxes give the Proxy Host local control to enforce security
on incoming Proxy Master connections. You can select any one of these options:

Š

Reboot on disconnect or termination—while this is checked, the Proxy
Host PC will automatically reboot whenever a Proxy Master disconnects
or the connection is terminated. This is useful to establish a standard
startup process on the PC, and to protect against accidental takeover of a
previous session.

Š

Disable keyboard and mouse on startup—while this is checked, the
Proxy Host PC cannot be changed by someone who has physical access
to the keyboard and mouse. This is useful to guard against tampering
with a configuration once the Proxy Host is started.

Š

Blank screen on startup—while this is checked, the Proxy Host PC
screen will be blanked (all video will become black) as soon as the Proxy
Host is running. This guarantees that any activity by a Proxy Master
cannot be viewed by a passerby.

If you have chosen one of the last two options, the “Confirm Security Settings”
message box will be displayed on the Host PC at Windows startup. To take
control of the Host PC before screen blanking and/or keyboard and mouse
disabling, answer Disable Security Settings within 30 seconds.

NOTE: Choosing one of the last two options and also selecting connection
permissions is incompatible, since the Host cannot acknowledge a message box.
If you attempt to do this, then No Permission Required will be forced as the new
setting.
