Citrix Recevier for iPad shows “Error” but Reciever for Android works

Posted on February 21st, 2012

Came across  this interesting problem today.

Users connecting to a XenApp deployment via a Netscaler 9.3 & CAG Enterprise Edition using the Citrix receiver for iPad and Android. Web Interface for Netscaler was used to provide the XenApp services site.

The Android receiver worked as expected but the iPhone/iPad receiver did not enumerate the apps. On the creation of a new connection, the following errors were shown:

  • iPhone: There are no applications available at this time
  • iPad: Error

After much messing about, it seems that when creating a XenApp service site on the Netscaler, a checkbox is provided stating “enable connection through mobile receiver”. When this is selected a few “rewrite” rules are created to resolve a problem with the iPad/iPhone receiver connections but the rewrite feature is not enabled at the same time on the Netscaler. Simply right clicking the “rewrite” menu in the left panel and selecting to enable the feature is enough to resolve the problem.

After doing this, all mobile receivers can connect as expected.

Customize logos on Citrix Access Gateway Enterprise Edition Logon Screen

Posted on July 12th, 2010

This is based on Netscaler version 9.2 Build although nothing appears to have changed from previous versions, so the same information will probably work on most Access Gateway Enterprise versions (CAG EE)

Change to a white theme

This is detailed in several places but most notably here: CTX123607

This gives the default logon screen in white.

Identify the images used

Here is a screen shot of the default view and list of the associated images & resolutions

There are five main images used in this page and they are:

Image Filename Dimensions
1 ctxHeader01.bmp 265 x 62
2 ctxHeader02.bmp 1175 x 62
3 LoginIcon.png 81 x 128
4 CitrixWatermark.gif 115 x 62
5 LoginPaneCenterLeftBorderGlow.png








As original

I have found it better to stick to the same dimensions when replacing these images as sometimes the style sheets need to be modified to allow larger image sizes. If you can, stick to the same dimensions.

The background for image 1 & 2 is in the image itself. If you want to keep the same shading and blue bar, then edit the existing image and keep the background.The same applies for the logon logo (image 3) as the shading is part of the image.

To modify the border glow it is best to open up the existing image and use the dropper tool to fill the line in the desired colour.

File locations

These image files need to be copied to the /netscaler/ns_gui/vpn_images location on the Netscaler device. However, when the netscaler is rebooted the changes are lost so they must be copied here at every startup.

Copy all the images to a folder under the /var/ folder (I use /var/mods/) and this can be the store for all modifications.

Startup script

The /nsconfig/rc.netscaler file runs at every boot, so add entries to this file to copy the modified files from the /var/mods/ folder to the correct location. For example,

tar -zxvf /var/mods/AGEEwhite.gz -C /netscaler/ns_gui/vpn/images
cp /var/mods/images/ctxHeader01.gif /netscaler/ns_gui/vpn/images/ctxHeader01.gif
cp /var/mods/images/ctxHeader02.gif /netscaler/ns_gui/vpn/images/ctxHeader02.gif
cp /var/mods/images/CitrixWatermark.gif /netscaler/ns_gui/vpn/images/CitrixWatermark.gif
cp /var/mods/images/LoginIcon.png /netscaler/ns_gui/vpn/images/LoginIcon.png
cp /var/mods/images/LoginPaneCenterLeftBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneCenterLeftBorderGlow.png
cp /var/mods/images/LoginPaneCenterRightBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneCenterRightBorderGlow.png
cp /var/mods/images/LoginPaneFooterLeftBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneFooterLeftBorderGlow.png
cp /var/mods/images/LoginPaneFooterMidBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneFooterMidBorderGlow.png
cp /var/mods/images/LoginPaneFooterRightBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneFooterRightBorderGlow.png
cp /var/mods/images/LoginPaneTopLeftBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneTopLeftBorderGlow.png
cp /var/mods/images/LoginPaneTopMidBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneTopMidBorderGlow.png
cp /var/mods/images/LoginPaneTopRightBorderGlow.png /netscaler/ns_gui/vpn/images/LoginPaneTopRightBorderGlow.png

Final steps

Ensure you boot the netscaler device to confirm the start up script is running correctly and make the same changes to the secondary device if running in an HS pair.

The web page can now look how you want it to!
