Quick configuration for IGEL Linux based devices without the IGEL Universal Management Suite

Tuesday, June 26th, 2012

Maybe you’re environment don’t need a UMS Server, UMS configuration is not possible or it’s just to small to setup an extra management server… A quick and easy configuration is also possible in environments like this, all you need is a FAT32 formatted USB Memory.

Note: If you want to deploy background pictures or firmware updates just create a folder on the USB Memory and place the files into this folder.

1) Setup the first thin client like you want it, enable at least one USB Device in the Devices->Storage Devices! If you want to use the USB Memory also to deploy firmwares, change the update settings to file and point to the folder on the USB Memory where the firmware or other files are placed. For all related settings point to the Update configuration (like background picture or in the flash player download configuration)!

2) Press ALT+CTRL+F11 and login as root, now execute “store_usbconfig”. You will be asked for the configuration name (you can store a couple of different configurations if required) and you’re done here.

3) Boot the client where you want to deploy the configuration and press ALT+CTRL+F11. Execute “load_usbconfig”, you will be asked to replace the existing configuration and after this you can select a configuration from the USB Memory. Reboot the device and execute the “update” command if you want to start the firmware update (needs to be configured and the firmware @ the USB Memory).

4) Proceed 3) at all clients where you want to deploy a configuration….

That’s it… If you want to switch back to the IGEL Desktop just press ALT+CTRL+F1.

Fixed: IGEL LX/OS and images are Tinted Blue in Published Photoshop when using XenApp 6 (CTX128332)

Friday, June 8th, 2012

In XenApp 6 environments it can happen that images are tinted blue in a published Photoshop session, for the Windows Citrix Receiver is a fix available which is mentioned here: http://support.citrix.com/article/CTX128332

To setup this for a Linux based IGEL Thin Client or a UDC converted device open the profile or IGEL Setup and set System->Registry->ICA->wfclient->enableoss to disable. In general tweaks like this can be found in the wfclient area in the IGEL Setup or the profile in the IGEL UMS. If a setting is not available it might be a good idea to contact the IGEL support to provide information’s like this to the IGEL development.

USB redirection issues

Wednesday, May 30th, 2012

If you enable USB redirection for Citrix XenDesktop, VMWare View, Fabulatech or Microsoft RemoteFX the rule to enable USB redirection in general does not mean that this will redirect all USB devices now. You need also to setup class rules (Printers, HID..) or device rules to get it working.

Configuring VMWare View Display settings

Wednesday, May 30th, 2012

If you want to setup the monitor configuration for VMWare View sessions, you need to configure this thru the RDP Global configuration in the IGEL Setup or UMS Profile. It’s not really clear and i noticed this today in a workshop, so a good reason to post it here.

Fixing WiFi connection issues when using IGEL Universal Desktop LX / OS

Thursday, May 24th, 2012

If you run into WiFi connection issues try the following settings as add-on to your WiFi configuration. All settings can be found in the IGEL Setup / Profile -> System -> Registry -> network -> interfaces ->wirelesslan.

wireless_mode = IEEE 802.11 b/g
device0.channel = Try to setup the used channel if possible

Make alway sure that you setup the right regulatory domain and location in the regular wireless configuration in the IGEL Setup, this can also cause a lot of issues if configured wrong.

Using Citrix VDI in a Box 5 with IGEL Linux clients (Firmware 4.09.100 or higher)

Saturday, May 19th, 2012

Hello,

before the firmware release 4.09.100 it was only possible to use Citrix VDI in a Box 5 thru the XenApp configuration in the IGEL Universal Desktop LX/OS but not with the Firefox browser. Since the 4.09.100 you can also use the firefox browser but:

You need to enable a setting in the registry for this, it’s only mentioned with a short context in the release notes for the 4.09.100 firmware.

Open the IGEL Setup or the UMS profile and go to System->Registry and enable the setting browser_plugin.ica.vdi_fix.

After this configuration the VDI in a Box Webinterface works like a charm for the users.

Improve USB storage write performance

Saturday, May 19th, 2012

To improve the write performance for USB storage devices in general follow these steps:

1) Open the IGEL Setup or your UMS Profile and go to System->Registry
2) Disable devices.autofs.sync_option

Note: This will not work for “true” USB Redirection (View, XenDesktop, RemoteFX, Fabulatech and so on) but it will improve the general performance for RDP, ICA and other drive mappings. Test in advance!

Cheers
Michael
