When you click
OK
, the primary user who is active will receive a request to allow sharing unless Automatic has
been enabled. If the user confirms, you will be given target access.
•
Preempt a user’s connection - When you are prompted to preempt the user’s session and you click
Preempt the
other user
, the user requesting access to the target will be connected and existing user(s) will lose their
connection to the target. The existing user(s) will be notified that their sessions have been preempted.
To display a list of users sharing their port or channel, select
View - Connected Users
in the Video Viewer window. Users in
stealth mode are excluded from this display.
Encryption level
In the Encryption Level area, specify an encryption level for the keyboard/mouse, video and virtual media:
•
3DES - SSL Triple DES encryption
•
128-Bit SSL - 128-bit encryption which used an ARCFOUR (RC4®) SSL cipher
•
AES - AES encryption
At least one encryption level must be specified for the keyboard and mouse. When you specify more than one SSL
encryption type, the appliance negotiates the strongest algorithm that is supported by both sides. The strongest algorithm
is AES, followed by 128 bit, 3DES and DES.
Session settings
Under the Session Settings heading you can configure the Input Control Timeout, enable and configure the session timeout,
set the keyboard language, set the EDID (video) resolution and enable video noise control.
NOTE: If a user connects to a target with a higher screen resolution than the local computer, the Video Viewer window
will display a portion of the target screen, with scroll bars for viewing the remainder of the screen. The user may view
the entire screen by adjusting the resolution on the target, the local computer or both.
Session preemption
Under the Session Preemption heading, you can enable preemption and set the time-out. Session Preemption Control
specifies whether the user will be notified before the KVM session is preempted. If Session Preemption Control is enabled,
the Session Preemption Timeout specifies the number of seconds to wait, after notifying a user the KVM, to preempt the
session.
For more information on preemption, see
Virtual media
Under the Virtual Media heading you can enable virtual media, lock to KVM session, allow reserved sessions and select the
virtual media access mode.
•
The locking option specifies whether a virtual media session is locked to the KVM session on the target. When
locking is enabled (default) and the KVM session is closed, the virtual media session will also be closed. When
locking is disabled and the KVM session is closed, the virtual media session will remain active.
•
Allow reserved sessions ensures that a virtual media connection can only be accessed with your username and
that no other user can create a KVM connection to that target. When the associated KVM session is
disconnected, the virtual media session may be disconnected according to the Locked setting in the Virtual
Media dialog box.
•
The virtual media access mode allows you to set the access mode for mapped drives to read-only or read-
write. When the access mode is read-only, the user will not be able to write data to the mapped drive on the
client server. When the access mode is read-write, the user will be able to read and write data from/to the
mapped drive. If the mapped drive is read-only by design (for example, a CD-ROM drive, DVD-ROM drive or
ISO images), the configured read-write access mode will be ignored. Setting the read-only mode can be helpful
when a read-write drive such as a mass storage device or a USB removable media is mapped, and you wish to
prevent the user from writing data to it.
You can have one DVD drive and one mass storage device mapped concurrently. A CD drive, DVD drive, or
ISO disk image file is mapped as a virtual CD/DVD drive.
