AWI Client: Connection Management Interface Session Settings

Select the Connection Management Interface session connection type from the Configuration > Session page to configure an external connection manager other than View Connection Server as the connection broker for the client to use.

Note: External connection managers can simplify the administration effort for large, complex systems. In a managed connection, an external connection manager server communicates with a device, and can remotely control and configure it. The connection manager can also locate an appropriate peer for the device to connect to, and then initiate the connection.

AWI Session Connection Type – Connection Management Interface (Client)

AWI Session Page Parameters

Parameter Description

DNS Name or IP Address

Enter the DNS name or IP address of the connection manager.

Enable Peer Loss
Overlay

When enabled, the “Network Connection Lost” overlay appears on the display(s) when a loss of network connectivity is detected. Normal hypervisor scheduling delays can falsely trigger this message.

Note: This option is only available for a zero client. Desktop applications that require the peer loss notification should re-enable the feature through the OSD, AWI, or MC.

Enable Preparing Desktop Overlay

When enabled, the "Preparing Desktop" overlay appears on the display(s) when users log in.

Note: This overlay provides assurance that login is proceeding if the desktop takes more than a few seconds to appear.

Enable Session Disconnect Hotkey

When enabled, users can press the Ctrl+Alt+F12 hotkey sequence to pop up the "Zero Client Control Panel" overlay, which lets them disconnect the current session on the workstation or power off the workstation.

Note: Before users can use this disconnect hotkey sequence, certain other configuration options must be in place. See Disconnecting from a Session for details.

PCoIP Utility Bar Mode (Tera2 zero clients only)

When enabled, the PCoIP Utility Bar appears at the top of the primary display when a user is in session and moves the cursor directly under the bar. The utility bar can be used to disconnect a session or to shut down a remote workstation. For Direct to Host session connection types, Local Cursor and Keyboard must be enabled in order for the zero client to process mouse events for the utility bar. For all connection types, the mouse must be locally connected (i.e., not bridged).

  • Disabled: Disables the PCoIP Utility Bar. Note: (By default, the utility bar is disabled.)
  • Enabled: Enables and auto-hides the PCoIP Utility Bar. Users can show the utility bar by pointing the mouse at the top of the screen directly under the utility bar. Users can slide the utility bar to the right and left at the top of the screen.
  • Enabled and Pinned: Enables and pins the PCoIP Utility Bar at the top of the screen. Users cannot hide the utility bar, but they can slide it to the right and left at the top of the screen.

Note: This feature is configurable from the MC and AWI only. It requires firmware version 4.2.0 or newer.

Enable Event Log Notification

When enabled, the client sends the contents of its event log to the connection management server.

Session Negotiation Cipher

Important: In release 4.8.0, the security cipher features listed below are supported on Tera2 zero clients only. In order to use a non-SHA-1 cipher, both the client and host endpoints must support it.

Note: For sessions with software hosts, the zero client should be configured to use the Maximum Compatibility option.

For Tera2 zero clients:

Configure the Transport Layer Security (TLS) cipher to use for negotiating the TLS session between the PCoIP client and the PCoIP host.

  • Maximum Compatibility: TLS 1.0 or higher with RSA keys including ciphers that use SHA-1: This option provides maximum compatibility.
  • Suite B: TLS 1.2 with Suite B-compliant 192-bit elliptic curve encryption. This option provides a higher level of security.
  • Disable SHA-1: TLS 1.2 with RSA keys and strong ciphers using only SHA-256 or SHA-384: When selected, only devices running firmware 4.8.0 or greater are affected.
    Note: Currently this option can only be used with Amazon WorkSpaces hosts.

For Tera1 zero clients:

Configure the Transport Layer Security (TLS) cipher to use for negotiating the TLS session between the PCoIP client and the PCoIP host.

  • Maximum Compatibility: TLS 1.0 with RSA keys and AES-256 or AES-128 encryption: This option provides maximum compatibility.
  • Suite B: TLS 1.2 with Suite B-compliant 192-bit elliptic curve encryption. This option provides a higher level of security.

Enabled Session Ciphers

Enable or disable an encryption mode for the device. By default, all encryption modes that pertain to a device are enabled.

  • AES-128-GCM (Tera1 and Tera2): An encryption method implemented in first-generation Tera1 and second-generation Tera2 processors. This method offers the best performance between hardware endpoints for Tera1 devices. AES-128-GCM also may offer improved performance for Tera2 clients when connecting to VMware 4 or newer if there is more than about 7 Mbps available on the network.
  • AES-256-GCM (Tera2 only): A more secure encryption method implemented in second-generation Tera2 processors that offers the best performance between hardware endpoints. When connecting to VMware 4 or newer, AES-128-GCM is recommended.
  • Salsa20-256-Round12 (Tera1 only): A lighter encryption method implemented in firmware that may offer improved performance for Tera1 clients when connecting to VMware View 4 or newer if there is more than about 7 Mbps available on the network.

Note: For more information about connecting to VMware Horizon virtual desktops, see “Using PCoIP® Zero Clients with VMware View User Guide” (TER0904005) in the Teradici Support Documentation Center.

Note: The enabled encryption mode must match between the host and client for a session to be established. If more than one mode is enabled, the firmware selects the following:

  • Host to Tera1 or Tera2 clients: AES-128-GCM or AES-256-GCM for the PCoIP session.
  • VMware View 4.5 and later to Tera1 client: SALSA20-256-Round12 for the PCoIP session.
  • VMware View 4.5 and later to Tera2 client: AES-128-GCM for the PCoIP session.

Disconnect Message Filter

This field lets you control what type of messages appear when a session is disconnected. There are three categories:

Information: User- or administrator-initiated actions affecting the session:

  • You have been disconnected because you logged in from another location or your host was shut down or restarted.
  • You have been disconnected because an administrator disconnected you.
  • You have been disconnected because you logged in from another location.
  • You have been disconnected because you disconnected from your workstation.

Warning: System-initiated, but expected actions affecting the session:

  • You have been disconnected because your session timed out.

  2. Show Error and Warnings Only – This option hides info messages and displays only error and warning messages.
  3. Show Error Only – This option hides Info and Warning messages and displays only Error messages.
  4. Show None – Don’t show any disconnect messages.

Enable DSCP

When enabled, the device populates the Differentiated Services Code Point (DSCP) field in the IP header, allowing intermediate network nodes to prioritize PCoIP traffic accordingly.

Enable Transport Congestion Notification

When enabled, transport congestion notification is enabled to allow PCoIP endpoints to react accordingly if an intermediate network node sets the congestion notification bit in either the IP header or PCoIP transport header.

Note: For more information about the PCoIP transport header, see PCoIP Packet Format.
