C HAPTER 4: A DMINISTRATIVE F UNCTIONS 49
− SSL authentication, SSL data encryption: This mode secures user names and passwords, and provides
high-level security for KVM data. 128-bit Secure Sockets Layer (SSL) protocol provides a private
communications channel between Dominion KSX and the Remote PC during initial connection
authentication. 128-bit SSL encryption is also in place during remote KVM data transfer.
Note: SSL data encryption increases the amount of data that must be sent over the remote
connection, and is, therefore, not recommended for modem or very slow Internet connections. The
default setting “SSL authentication, data encryption” offers exactly the same level of security with
a higher level of efficiency.
• Remote link blanks user port: Determines whether the Direct Analog User port will be blanked out locally
when a remote user is accessing the corresponding KVM port. This keeps a local user from seeing what the
remote user is doing.
− NO (default): User port can be viewed locally during remote user access.
− YES: User port cannot be viewed locally during remote user access. The local or Direct Analog user
console will stop displaying video.
• Allow remote administration:
− NO: To keep access to all Administrative Functions available only from the Dominion KSX Admin
Console, and not from a Remote PC.
− YES (default): Allows remote access to all Administrative Dominion KSX Functions by administrators
logged on at a Remote PC. See 9. Remote Administration.
• PC Share Mode: Determines global concurrent remote access. Enables up to eight remote users to
simultaneously log on to one Dominion KSX unit and concurrently view and control the same Target KVM
Server through Dominion KSX. Control is based on first active/keyboard mouse input, so multiple remote users
attempting keyboard input or mouse movement at exactly the same moment may experience uneven control.
− Private Mode (default): No PC Share. Each Dominion KSX path can be accessed exclusively by only one
user at a time.
− PC Share Mode: Dominion KSX ports can be accessed by more than one user (administrator or non-
administrator) at a time. Control is based on first active keyboard/mouse input, so multiple remote users
attempting keyboard input or mouse movement at exactly the same moment may experience uneven control.
− PC Share Admins Only: Dominion KSX can be accessed by more than one user (administrative users
only) at a time. Control is based on first active keyboard/mouse input, so multiple remote users attempting
keyboard input or mouse movement at exactly the same moment may experience uneven control.
Note: PC Share Mode is a global setting. For individual user access settings see Keyboard and
Mouse Control and Concurrent Access Mode on the User Account Settings screen. Each user
profile can be set individually to enable/disable keyboard and mouse control, and concurrent
access.
• Logout idle users: Offers an option for Dominion KSX to automatically disconnect remote users after certain
selected time intervals of inactivity have passed.
− Never (default): Idle remote users will never be disconnected.
− After 5, 15, 30, 60, or 120 minutes: Idle remote users will be automatically disconnected from Dominion
KSX after the selected time period has passed with no active input from the Remote PC.
• Restrict remote IP address: Determines which remote IP address locations will be granted access to Dominion
KSX.
− NO (default): Remote access to Dominion KSX is unrestricted.
− YES: Dominion KSX will grant remote access to up to four designated IP addresses or address levels.
Administrators can set Dominion KSX to accept requests only from the company’s intranet and/or from
just a few outside IP addresses
. The IP Mask fields determine what remote IP addresses Dominion KSX
will grant remote access to.
A specific IP Mask instructs Dominion KSX to grant remote access only to this specific remote IP address. For
example, a mask of 10.0.0.1 instructs Dominion KSX to grant remote access from the remote IP address
location 10.0.0.1 only.
The value 255 acts as a wildcard in any location of the IP mask address. For example, a mask of 10.0.0.255
instructs Dominion KSX to grant remote access from any remote IP address location within the range 10.0.0.0
to 10.0.0.255. Similarly, a mask of 192.255.255.255 instructs Dominion KSX to grant remote access from any
remote IP address location beginning with 192.
