Using Citrix GoToMeeting with Citrix XenApp or XenDesktop

Wednesday, September 18th, 2013

Hi Folks,

maybe this information is useful: If you want to use Citrix GoToMeeting you should be aware that you can not use GoToMeeting  together with an Audio Headset and XenApp.

If you are using XenDesktop together with a Desktop OS (not Server OS!) then it will work and you can use the Headset.

This is not related to IGEL, it’s a general behavior for GoToMeeting together with XenDesktop/XenApp and the Client OS (Windows/Linux) is not important!

Cheers

Michael

P.S.: Future versions of GoToMeeting maybe will not show this behavior… 🙂

Solution: cloud-client.info introduces first Apple device support for Linux based Thin Clients

Friday, August 30th, 2013

Hi folks,

so often i’ve been asked to use Apple devices like the Iphone, Ipad or Ipod with an (IGEL) Linux based thin client without using (expensive) USB redirection solutions…

Here is our first custom partition sample introducing Apple device support for all Universal Desktop LX/OS (x86) based devices!

atunes

Apple devices can be used local, in Microsoft Remote Desktop sevices or Citrix sessions and more. The pack includes also a local running Application (Atunes) which works quite similar to Itunes. Itunes will not recognize the device in a terminal server session but you can use file based Itunes alternatives and access the Apple device file system to copy pictures or what ever!

This solution is tested with various Apple devices (Iphone 4, Iphone 5, Ipod 7gen and Ipad 3)but please note: No one will support it. 😉 A jailbreak is not required… 😀

To read more or download the solution klick here: Apple device support

The package is modular designed, so you can seperate not required functions like aTunes….

Have fun and a nice Weekend!

Michael

 

P.S.: Regarding the fact that i don’t own any Apple device i want to thank all guys that borrow me a device without being afraid that i damage any device during my test’s… 😀

Tip: Fixing Keyboard Layout Issues with VMWare Horizon View Client 2.0 for Linux and Mac OS X

Thursday, July 11th, 2013

Hello Folks,

it looks that the current VMWare Horizon View Client for Linux and Mac OS X have an issue with Keyboard mappings, for example you are using Scandinavien or Swiss Layouts on the PC / Thin Client and in the VM the Keyboard Layout changes to English(US). It also looks that it doesn’t matter what Keyboard Layout’s are available in the VM, so as sample also a pure German VM without any US Settings/Layout available(!) switch to English(US).

This behavior is also only related to the current Horizon View Client (IGEL Firmware = 4.12.100), older Clients from VMWare are working fine in my known cases (IGEL Firmware < 4.12.100) incl. the current Client for Mac OS X which shows the same "wrong" behavior like the current Linux Client (old OS X Clients are working fine too). A Workaround to fix this issue is the following registry tweak for the VM's which can be applied thru a Group Policy or set in the local RegEdit if needed. Open the Registry and browse to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout Create a new Registry Setting: Value name: IgnoreRemoteKeyboardLayout Data type: REG_DWORD Value data: 1 Apply the setting/policy to the affected VM's only, the issue should be fixed now and the language settings in the VM will be used for the session. As said and in general, the issue can happen but it don't have to be... Only use it if required, i will not provide any warranty at all and you do this on your own risk. Cheers Michael P.S.: This will also fix issues with other Windows based Remote Sessions like RDP, ICA or whatever if you run in a similar issue. Please note: After done this setting the local client keyboard layout will always be ignored.

Tip: Citrix session drops if you open a second ICA connection in a XenApp/XenDesktop session

Tuesday, July 9th, 2013

Hi Folks,

i just got an issue where the user opens a session from an IGEL Linux / Windows PC to a XenApp / XenDesktop environment. This works fine until the user starts a second session in the first session to an other XenDesktop/XenApp environment.

The connection are done thru a Storefront server.

If this issue happens also to you, try the following registry setting in the Server / Desktop the user connects first.

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Citrix\Dazzle]

“WSCReconnectMode”=”0”

Please note: Test in advance, i do not provide any warranty that this will fix the issue at all or for a data loss in case of a wrong impementation. You are fully responsible if you apply this setting!

Tip: USB Storage security with IGEL Linux (LX/OS)

Thursday, June 6th, 2013

Hi Folks,

maybe you already noticed that you have an USB Security configuration in the Device section of the IGEL Setup.

If you want to allow a special USB Memory mostly people use the Vendor ID (VID) and Product ID (PID) for this. This works quite well but has one big disadvantage…. It works for all USB Memory with the same VID and PID.

To extend this, you can use the UUID (Unique ID) but how can you setup this?

1) First of all, it will only work with an Filesystem that supports a UUID… NTFS will do, FAT16 or FAT32 will not. So you need to format the USB Memory with NTFS.

2) Now use a thin client where one or more storage devices are allowed without any USB restrictions.

3) Open a console session and type in the command: “ls /dev/disk/by-uuid”. You will get a short list now and insert the USB Stick. Type in “ls /dev/disk/by-uuid” again, compare these lists and write down the new one. The UUID should look like “FE1CFEABB210AA”.

4) Create a new USB Device configuration and type in the PID/VID and the UUID you have written down and assign the configuration to a client. Don’t forget to allow HID devices (Mouse/ Keyboards) in General before assigning the configuration. For VID and PID, use always 4 Digits like 0C00 and remember: Linux is case sensitive! If you don’t know how you can get the VID and PID type in lsusb.

5) Done… Now you have a unique USB Memory to use with the client, all other will not work anymore. Also if someone format this USB Memory it will also not work anymore. Secure and easy to setup.

Tip: Troubleshooting VGA Display issues for IGEL Linux based Operating Systems

Friday, May 31st, 2013

Hi Folks,

if you’re using a Linux based IGEL Thin Client together with an analog Monitor or TV and you get only a black Screen/frequency error or the Monitor goes in the standby mode this article will provide you some guidance how this can be fixed.

1) Don’t use a KVM Switch in general for your tests.

2) Make sure that you have the right VGA cable in place, there are two Versions available: 14 and 15 pole. Depending on the Display you could be required to use an 15 pole cable.

3) Not all issues can be fixed and if possible test also the connection with a DVI cable.

4) If using a DVI-I splitter cable to VGA / DVI-D make sure that the cable is an original IGEL Y-Cable or if using a Universal Desktop OS converted device a Y-Cable certified by the Vendor of the inbuild Graphic Card. Splitter cables DVI-I to 2x DVI or DVI to 2x VGA (both are not DVI Standard and only used if a vendor extend the DVI standard by there own) are not supported with original IGEL Thin Clients, for Universal Desktop OS converted devices this depends on the inbuild GFX Card: Please contact the hardware Vendor in this case.

5) If you’re using VGA and you got an issue try the following Settings in the IGEL Setup->System->Registry:

x.xserver0.analog_timings= Enabled
x.xserver0.connector= VGA, if you’re using two Displays also set x.xserver0.screen1.connector to the right port
x.xserver0.noddc= Enabled

Assign the configuration and reboot the device, if this did not solve the issue try 1-4 or open a support case at IGEL but mostly the issue should be fixed thru these Settings.

Cheers

Tip: Setting default ICA (Citrix) Audio Device for a IGEL Universal Desktop Linux based OS

Monday, March 25th, 2013

Hi,

if you’ve connected several Audio Devices to an IGEL Linux based Thin Client, you might want to be able to configure the default Audio Device for your Citrix Session. This will only work for IGEL Firmware with Citrix Receiver 12 or 12.1!

Currently this can’t be done via the IGEL Setup but there is a way how this task can be performed.

First of all: This will only work as long the Client configuration is not touched or modified by the IGEL Universal Management Suite or the local Setup! If you change something here, you have to reboot the Client to setup the configuration again.

Preparing the configuration: Connect all Audio Devices to the Thin Client and open the Sound Mixer Tool (Speaker Symbol in the Taskbar), to open the Tool use the right mouse button and click on the Symbol->Select Audio-Settings

Now select Input and click on Advanced Settings, in the drop down menu “Soundcard” write down the name for the device without the (Alsa mixer) extension. Sample UD5 Internal Soundcard= HDA VIA VT82xx or the 1st USB Headset = USB Headphone Set

After this is done and you got the name for the Audio Device close the Audio Mixer and open the local IGEL Setup or the UMS Profile. Now browse to System->Firmware Customization->Custom Commands->Desktop Commands->Custom Command Desktop final and enter here:

echo “[ClientAudio]” >> /config/ica/wfclient.ini
echo “AudioDevice=HDA VIA VT82xx” >> /config/ica/wfclient.ini

Replace HDA VIA VT82xx with the name of the Audio Device you want to set as default, after this is done you can assign the configuration and reboot the device. Now the default Audio Device is configured until a new Audio Device is connected to the Client, a new device will be automaticly set as default.

For Firmwares with an ICA Client 11 or older change the Audio Device Name to /dev/dsp0 (1st Audio Device) /dev/dsp1 (2nt Audio Device) and so on…. The ICA Client Version 11 and below is using an other Audio System and will not work with the Device Names shown in the Sound Mixer.

Cheers

Tip: Tabs bar is not hidden in the IGEL Linux Firefox/Webbrowser if starting/configured for a Kiosk mode look and feel

Thursday, March 14th, 2013

Hello Folks,

if you’ve configured the Firefox Browser coming with the IGEL LX/OS Operating System to start in Kiosk Mode (no menus available) you maybe have noticed that still the Tabs bar is shown and the user can open an other Website. I’ve currently not found a setting in the regular IGEL Setup GUI but you will found it in the registry.

To hide the tab bar again open the local Setup or the UMS Profile and browse to System->Registry->Sessions->browser*no*->app and enable the setting “tabs_bar_hidden”, after this configuration is applied the tab bar will not be shown anymore.

This is related to the newer Firefox Versions coming with the IGEL Linux and you will not see this issue with older Firmware Versions.

Cheers

Michael

P.S.: There are a lot of more Settings in this part of the registry to configure the browser session a lot more then in the GUI, just check it out.

Test: Using IGEL Linux based Thin Clients together with Citrix CloudGateway Enterprise

Friday, February 15th, 2013

Hi Folks,

today i’ve tested the IGEL Universal Desktop LX/OS together with Citrix XenApp 6.5, XenDesktop 5.6 and VDI in a Box 5.2 and Citrix CloudGateway Enterprise (LAN and WAN thru Citrix Netscaler).

I’ve used the internal Webbrowser coming with the IGEL Linux for the connection, in both cases (LAN and WAN) it works like a charm. For my test i’ve used the IGEL Firmware 4.11.100.

CloudGateway thru IGEL Universal Desktop LX Webbrowser

 …and connected to a session (XenApp 6.5)

 

Connection thru CloudGateway to XenApp 6.5


If you plan to upgrade your Citrix Environment to CloudGateway this should work for you, so the IGEL Linux based Clients seams to be ready for the new Citrix products. Official i’ve read no confirmation from IGEL about this, so in anyway you should test this to confirm the results. If you discover issues here feel free to contact me.

Update: I forgot, in the screenshots the Desktop Connections to XenApp,XenDesktop and VDI in a Box are missing but i works also fine for me.

Cheers
Michael

P.S.: The old PNAgent Service Site is now called “Legacy” in Citrix products…..

Tip: Setting up a disclaimer for public used IGEL Linux based Terminals.

Friday, February 15th, 2013

Good morning,

i’ve been asked if it is possible to Setup a public dislaimer with use Terms for the IGEL LX/OS based Clients.

This can be done but the configuration is hidden in the registry, open the local IGEL Setup or the UMS Profile and browse to system->registry->userinterface->disclaimer. Here you will find several Settings to configure the disclaimer, the disclaimer will pop up after a boot and prevent Access until the disclaimer is confirmed or perform a shutdown/reboot after the user denied the disclaimer.

Cheers

Tip: Fixing mouse pointer issues with IGEL Universal Desktop LX/OS

Friday, February 1st, 2013

Hi Folks,

this is really rare but sometimes it might happen that you have issues with the display of a mouse pointer in an ICA or RDP session. If this is the case, try first this setting: IGEL Setup or Profile->System->Registry->x.xserver0.sw_cursor

Mostly this will fix the issue.

Cheers
Michael
