Thin Clients, VDI and Linux integration from the front lines.... Raw and sometimes unedited notes based on my experiences with VMware, Thin Clients, Linux etc.

I Had a client ring in with an issue today, although they are still testing, they wanted to be sure that the Speed Screen Latency was enabled for the users testing from Johannesburg, Sth Africa. They pointed out that they had already checked CTX103204 and CTX344154.
 
I had a quick check of these and then rang him back and we initiated a GoToAssist Session. I explained the background of the template.ica file as it has been used in the older NFuse Implementations and how it is now based on the default.ica file in ver.4. I also pointed out that there is also the three other "templates" for the ica file depending on the bandwidth available (high, medium and low), and how these can be set by the user under "Advanced Settings" prior to login.
 
Interestingly the details in the CTX344154 actually appear to be incorrect, although it states in CTX344154 that these ZL States can be set under the [NFuse_IcaWindow] the default.ica file actually states in the preamble at the start of the file that all NFuse_XXX settings are ignored. When we examined the default.ica file for Low Bandwidth the details for the ZL States are just set under the general [Application Settings](?)
 
After I discussed this with the client he decided that for the moment the default.ica file has been modified to add
ZLKeyboardMode=1
ZLMouseMode=1
so that all users will have this setting enforced. I also pointed out to the client that he really should then check this is the case with further testing to ensure that this is the case. We were unable to test this reliably from his PC at the time due to the fact that he had been running PNAgent on it also and this had appeared to cause some instability on his PC but not others.
 
I also pointed out that if he wanted to seriously stress test this component/function then he might check out something like
www.shunra.com who do have trial copies of their product available that can mimic high latency connections to validate their checks.

+++++++++++++++CTX344154 Details++++++++++++++++++++++++++++++++++++++++
To enable SpeedScreen Latency Reduction for NFuse / Web Interface applications, modify the Template.ica (default.ica in Web Interface 4.x) file with the following entries under the [NFuse_IcaWindow] section.

[NFuse_IcaWindow]
ZLKeyboardMode=1
ZLMouseMode=1

Now when you open ICA Connection Center, you will see SpeedScreen Latency Reduction = ON.

Hopefully this is of some help to others? and I'll chase up the typo(?) with Citrix tomorrow
