Keyboard layout problems with Sun Ray Connector for VMware VDM

[originally posted by Sarah Fortune 24-Feb-09]

There have been a couple of problems reported with international keyboards and the Sun Ray Connector for VMware VDM.

Some of the issues are:

  • Inability to enter characters that require Alt Gr combinations
  • When numlock is enabled the Enter, backspace and arrow keys don't work
  • In the Windows session, the keyboard is mapped as US

The first two are caused by a problem with Java and xkb. The solution is either to turn of the xkb extensions using this command '/opt/SUNWut/bin/utxconfig -k off' in the kiosk script: /etc/opt/SUNWkio/sessions/vdm/vdm. Using Java 6 also solves these problems, (you will need the Java 6 update 12 JDK, other versions can cause problems). You may need to change the kiosk script to point to the correct Java install. Change the line 'theJavaExec=/usr/java/bin/java' to point to the new location.

The third problem is due to the locale not being set for the windows session. You can set it in two ways. In the Sun Ray web administration go to Advanced > Kiosk Mode > Edit and enter the correct value for Locale. Or you can pass the locale as an argument to the kiosk script. On the same page add the argument -l <locale> after the double dashes.

The names of the locales can be found here. These solutions assume that everyone on the site is using the same keyboard layout. Other configurations will require some extra changes to the kiosk script, that's left as an exercise to the reader.

Thanks to Tomas O'Connor for the solutions.

Original Comments:

The issue with numlock is not limited to international keyboards. We have the described behavior with type 6 (on Ray 1) and type 7 (on Ray 2) keyboards, with SRSS 4.1 and 4.2 early access on Solaris/x86. We have not tested java 6 jdk, but the problem exists in jre 1.6.0_13-b03 shipped with early access.

Thanks for the note on this issue.

My mistake, jre 1.6.0_13-b03 does indeed fix the issue.
http://blogs.sun.com/mprove/entry/srvc11 says "some minor bug fixes, e.g. the Java 5/6 issue to solve some keyboard issues (http://blogs.sun.com/sjf/entry/keyboard_layout_problems_with_sun) is gone" but this doesn't include the numlock issue in my earlier post.

Hi I've configurated the locale settings in the advanced tab of srss web interfaces but nothing happen

srss 4.2 srvc 1.2 locale = it_IT

what do you mean with " after double dashes" where?

thanks

Troubleshooting Sun Ray Connector for VMware VDM

[originally posted by Sarah Fortune 3-Dec-2008, updated 26-May-2009]

This page is updated as more solutions become available, also see this page for keyboard issues.


Log messages

The log messages for the VDM connector are located in /var/opt/SUNWut/log/messages
Look for messages beginning with 'kiosk:vdm'.

It may also be helpful to look at the VDM Connection Broker log messages, they can be found in the VDM web administration under Events.


Error connecting to VDM server: javax.net.ssl.SSLException: java.lang.RuntimeException

Error message: 

Error: Error connecting to VDM server: javax.net.ssl.SSLException:java.lang.RuntimeException:
Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty 

Solution: 

The SSL certificate is not set up correctly on the Sun Ray server. Follow the instruction here: http://blogs.sun.com/mprove/entry/setting_up_ssl_and_sun


This desktop is currently not available. Please try connecting to this desktop again later or contact your system administrator. 

The desktop sources for this desktop are not responding.  Please try connecting to the desktop again later, or contact your system administrator

There are several causes for these error messages. They usually means the desktop is not set up properly, or is already in use. 

Some of the possibilities are:

  •  Some one is already logged in that machine (over remote desktop or via the console in VirtualCenter).
  • The machine is powering on/off or suspending.
  • There are no free desktops for that user.
  • The VDM tools are not installed on the desktop, or are not working correctly. Check that the desktop status is available in the VDM web administration.
  • Active Directory and/or DNS is not setup properly on the desktop.
  • There is a network communication problem between the VDM server and the desktop.
  • Windows firewall is blocking connections to the desktop.

There may be more details in the VDM event log in the web administration. You can get help with the VDM configuration on the VMware communities site.


Connection tunneling is required to connect to the desktop but it is not supported by this client

Connection tunneling provides security across a WAN. It allows an encrypted connection from the client to the desktop, by tunneling it through the VDM server. To use the Sun Ray VDM connector, you need to disable connection tunneling.

VDM 2/2.1: 

Open the VDM web administration, go to Configuration and enable

     "Direct Connect to virtual desktop"

VDM 3

Open the VDM web administration, go to Configuration > VDM Servers > Edit, and enable

     "Direct connection to desktop"


Exception in thread "main" java.lang.NoClassDefFoundError

Solution:

This error occurs if you are using an incorrect version of Java, Java 1.5 is the supported version. If you want to use Java 6 you will need the Java 1.6 update 12 JDK.


Desktop tries to open but immediately disconnects

Error message:

Dec  3 12:41:17 host kiosk:vdm[12656]: [ID 702911 user.error] uttsc exited with errorcode: 1

 Solution:

There are several reasons why this error message can occur. To diagnose the problem further, try to connect to the desktop manually from the Sun Ray Server using:

    /opt/SUNWuttsc/bin/uttsc <desktop IP>

It should open a remote desktop connection to the virtual machine. If it fails, it can give you an error message with some further information.


This desktop is not currently available

Hotdesking is not enabled in the Sun Ray VDM Connector 1.0, so if your desktop session is already in use, it will be unavailable if you try to use it from a Sun Ray client.  Yes, this is contradicatory to the behaviour of other clients, but it has been fixed in version 1.1.


Usernames containing spaces are not correctly detected

Problem:

If the user name assigned to a token contains spaces, then only part of the name will be automatically entered in the login window.

Solution:

There is a problem with how spaces in the user name are handled in the kiosk scripts. You can get versions of the scripts containing the fix here: vdm and vdm-user.sh. You will need to replace the files:

/etc/opt/SUNWkio/sessions/vdm/vdm
/etc/opt/SUNWkio/sessions/vdm/vdm-user.sh

It is necessary to restart any existing kiosk sessions for the changes to be applied.

Original Comments:

 

Issue:
- Having a user already connected to a desktop via Sun Thin client, if the same user tries to connect to the same desktop from a second thin client, the system doesn't allow him to connect and send the following error: " All available desktops source for this desktop are currently busy"

Other:
- Performing the same same test but using Wyse client, View Client or RDP will not give any error and works as designed (the first session is disconnected and user can login).

Desktop tries to open but immediately disconnects

Running SRSS 4.1 with SRVDM 1.1

getting error:
ay 20 13:43:35 <server> kiosk:vdm[29861]: [ID 702911 user.error] Error: Could not locate Virtual Machine for 'username': exit code: 2 Java Accessibility Bridge for GNOME loaded.

May 20 13:43:35 <server> Error: Internal error parsing response from VMware View Manager: Premature end of file.

any ideas?

Hi,
Has anyone experienced issues when the username (under &quot;Owner&quot; in token registration) has a space, hence; &quot;lastname firstname&quot;. It fails to pass the full information to the VMView server on logon. Hence when that user inserts the smartcard, it displays only LASTNAME in the User Name field.
Cheers, Ed

I'm using Sun Ray connector for VMWare View...

Posted by Eduardo on May 21, 2009 at 12:51 PM GMT 

Hello all

Jose you can tell the view manager to allow session override, works flawless on our configuration.

The problem we have is if you use Xinerama with two SunRay FS the ViewClient display is splitted betewen two monitors and there is no way to move it. At least we were unable to find it.

Sunray Server 4.2 and Solaris x86 v 10

Regards
