Sun rays missing keystrokes

We started seeing a very odd problem on our Sun Rays this morning. Keystrokes get missed!
You can be typing and for five seconds or so your keystrokes are simply ignored. Then it picks up where you left off (and the keystrokes you had lost do not flood in when things resume).
Could this be a resource availability issue? Nothing has changed config wise with our server in a couple of weeks and they've been working well since then. The only thing that's changed is we've added maybe sixty or so to the system.

This turned out to be an issue with one of our Windows terminal servers.

How to configure Firefox to use cert from smart card reader on Sun Ray 3 Plus

I have a Sun Ray 3 Plus configured so the user needs a smart card to login (CAC card) and bring up a Java Desktop on the Sun Ray Server (Solaris 10 SPARC).
Now I am trying to get Firefox to read the certificate from the smart card reader but not sure how to go about doing that.
From searching online, it seems like I have to load a module in Firefox:
Edit -> Preferences -> Certificates -> Security Devices
But what file do I load? I'm assuming it is a file that's part of the SUNWut package?

I try to test bumblebee with:
optirun glxgears
but I get this error:
Xlib: extension "GLX" missing on display ":8".

Sun Ray Client and VDI 3.0

Hello,
I have a working VDI 2.0 setup and an evaluation VDI 3.0 setup. However, when I point my Sun Ray term, using the GUI firmware, to the VDI 3.0 server I don't get a login screen - just that its connected.
Am I missing something?

Hi again, I just replied to your other thread.
I was having the same problem, when I assigned the pseudo token ID to a virtual machine/desktop.
If that's the case, try unassigning it, and you should get the login prompt.

US Keyboard Mapping on Sun Ray

I am using a Zenity Dialog for password entry, this then gets passed to the uttsc session.
Initially I checked the xorg.conf file on the host Solaris server and changed the keyboard to gb... This worked on the Server (logged off and logged back on and @ worked.
However, my Zenity dialog still has a US keyboard and my UK based customer has complex passwords utilising £"@$ all of which are in different places on US and UK keyboards.
Thanks,
Craig

There are two things that might cause this. The first is that the keyboard might not be telling the Sun Ray that it is a UK keyboard. The second is that 'zenity' (or its underlying Gnome libraries) is not reacting correctly to the notification that the keyboard layout has changed from the initial default US layout to a UK layout. It's possible that both of these things are happening.
If you adjust your kiosk script to wait until at least one keystroke has been collected before you launch 'zenity' to collect the user's password (perhaps by adding an earlier invocation of 'zenity', but anything that waits for a keystroke will do) and the keyboard still behaves as a US layout then there's a good chance that the keyboard isn't reporting its layout correctly. Low-end keyboards typically don't report their layout at all. They report a layout code of zero and expect the system to guess the appropriate layout. If this is what's happening then you can either reconfigure the server to treat a layout code of zero as a UK layout (see [http://blogs.sun.com/ThinkThin/entry/using_sun_rays_with_non] and be sure to check the final comment because at least one of the paths in the article is incorrect) or you can tell the DTU to report a UK layout when it gets a zero from the keyboard. To do that, see the 'kbcountry' keyword in the utfwadm man page ([online here|http://wikis.sun.com/display/SRSS4dot2/Solaris+Sun+Ray+System+Administration+Commands%2B-+man(1m)#SolarisSunRaySystemAdministrationCommands-man(1m)-manutfwadm1m]), or configure it in the DTU's local GUI if it's running GUI-enabled firmware.
If 'zenity' gets the right layout when launched after a keystroke has been collected but not when it runs before a keystroke has been collected then the keyboard is reporting the correct layout and the problem is probably that Gnome is not reacting correctly to a layout-change notification issued by the X server. Editing the keytable to associate a UK layout with keytable 0 might be a workaround for this, because that will cause the X server to present a UK layout from the very beginning, instead of starting with a US layout and then switching to a UK layout when it sees the first keystroke. (Until it sees a keystroke the X server assumes that it will be using the layout associated with code zero, which in the keytables as shipped is a US layout. Then when it gets a keystroke report from the DTU it switches to the actual layout code associated with that keystroke. It does this every time it sees a new layout code.)

How can I redirect USB from Sun ray to Win2003 terminal server

Hi
I am running Sun Ray 4.2 in Solaris with SRWC 2.2 in a Kiosk mod to Windows terminal server 2003 , how can I allow users to use their USB divices from Sun Ray and appear automatically in their Windows desktop ..I try adding the following line to mikioskhdlr_win script
UTTSCPARMS="-m -b -A 24 -r sound:high" - r disk:M=/tmp/SUNWut/mnt/$USER
but it did not work .. please help

If you are using the USB Drive Daemon or manually specifying the mount then there are no issues with user access. That's only an issue with the the built in USB pass through included with SRSS 5 which is connecting directly to Windows and in essence the physical machine. The former is just mounting a network drive which is user specific.

Intermittent missing keystrokes on macbook pro keyboard..hardware/software?

I have a mb pro 2ghz core duo and have recently been having keyboard problems. Intermittently, my keyboard will not recognize keypresses from the following keys:
zero -
p
; return
Sometimes when I reboot they work. I have to carry an external keyboard with me on the road otherwise I can't use the laptop. Do you think this is a software or hardware issue? When I use Cmd-S at startup, I boot to the root prompt and things seem to work at the command line interface. I type reboot to get into os X gui environment, then its hit or miss. I hate to send in my mac for a software issue and wish someone could shed some light on this for me.

Search "keyboard delay", "keyboard sleepy", or "missing keystrokes" . At this moment no fix. Just a half worarround.

Using USB printer on Sun Ray 2

Can someone direct me to a document or explain how I can configure the Sun Ray Software to allow me the ability to print to a USB printer attached to a Sun Ray 2 thin client. I believe this is possibele using the USB redirection utility but only when connecting to Windows XP desktops. I see it's being done when connecting to Windows 2003 Terminal Server. Any help or info on this would be great.
Thanks!

Here is a repost of my article on the sun-ray users mailing list.

This article is for using Solaris as the Sun Ray server.
I have used a Sun-Ray local USB attached printer in two ways.
Precondition1: The printer was using Postscript rendering.
The printer had its own rendering engine.
The printer was NOT a dumb windows-driver dependant printer.
Precondition2 the user logging on needs to have the printer administrator RBAC role to be allowed
to create /destroy printqueues.
1) Printing from Solaris.
Set up a solaris printqueue with
lpadmin -p printername -v " sunray devicename" -I postscript -T PS -m printermodel
This will use the solaris lpfilter mechanism to convert the printdata to postcscript protocoll.
2) Printing from Windows.
Set up a solaris printqueue with
lpadmin -p printername -v " sunray devicename" -m printermodel
Set up the windows printer with a working windows Postscript driver.
The windows included hplaserjet-postscript driver works. for a hplaserjet printer.
or any printer emulating the HPlaserjet like many Xerox printers do,
This setup will generate the Postscript protocol on the windows PC , and it will merely
"pass-though" the Solaris spooler without change.
So if you need to print from both the SR server and the windows PC you need to define two spooler queues for each printer. Below are two scripts that have existed in various versions on sun-rays.org that I enhanced a bit and ran from the VDI superstructure to make it do what I wanted. For windows printing you then need to pass the printername as an argument to the "uttsc" startup command.
uttsc ......... -r printer $printername .........
# the SCRIPT "set-printer.sh" for printing from a unix desktop

PrinterName=$MACAddr

if [ -n "$PrinterPath" ] ; then

else

fi
else

Bug or wrong configuration of the Sun Ray Server+DTU+17" and 24" screenres.

I have 2 DTU, one has a 17" screen with a resolution of 1280x1024 and the other DTU has a 24" screen with a 1900x1200 resolution attached. The setting of the Sun Ray server is configured only that registrated cards, can make an kiosksession to VMware View 4.6.
When I start the DTU's, there is nothing wrong. The correct screen resolution is displayed on the screen for both DTU's. When I put a smart card into the DTU that has a 17" attached, it's indicates the correct resolution. The problem starts when I hotdesk to the other DTU with the 24" attached to, the session what was builded on the 17" will be showed on the 24". So the the resolution is 1280x1024. With this action there's nothing wrong, because the kiosksession is made on the 17" and no disconnection is made, so this is a correct resolution at this point. When I pull the card out of the 24" DTU, the screenresolution will be still at 1280x1024. It's looks like the setting will be saved on the DTU. Only a restart of a DTU will turn back the good resolution.
When I do the same as the case before, but only I start at the DTU with 24" screen the kiosksession will start at 1900x1200. When I hotdesk to the Other DTU the kiosksession is still at 1900x1200, but only this time when I pull out the card out of the 17" DTU, The DTU will give the right screen resolution of 1280x1024
the DTU's are Sun Ray 3 Plus, it doesn't matter which DTU's I place, the problems seems like that the DTU will save the last screen resolution. I got 300 of these DTU's and try a lot of them, but still the same issue.
Note: with each case explained in this thread, the kiosksession will be started at first time, the kiosksession is not builded yet or has been disconnected.
This behaviour is with a standard installation and configuration of Sun Ray server software 5.1.2. No extra script is implemented. Also I tried the UTRESIZE script that I've found on this forum, but it didn't helped.
Is this problem a bug (known issue) or is this a wrong configuration of me? This is a big issue for me

I have also a lot of fun with different screens, so I walk the "hardwired" mostly when I run into my screen does not look like correctly.
utresadm -a -c MAC -t default 1280x1024@60 ... and then this is nailed, whatever you do with this box. Very effective especially for beamers ...
what you can set, utresdef is your friend, utresadm -p show all the devices overwritten in case you need to change for a new monitor. And finally utresadm -d -c MAC -t default clears the setting.

Sun Ray - How to get external USB Card Reader working

Dear All,
i have the following problem. Maybe someone could help me or give me a clue to solve it.
SunRay Software 5 installed
Window 2003 R2 TerminalServer
Here my question:
I use a kiosk session with a smart card to conncet to the windows server - works perfect.
Login Screen and go.
Now i have to have to authenticate myself with an external usb card reader and smart
card (connected to the sun ray) to use a certain application on my win2003 server.
Via the windows rdp session (from the laptops) everthing is ok. The information from
the card reader is transferred to the server.
If i use the Sun Ray nothing happens. So here is my problem:
How do get the authentication information from the smart card to the server?
Thanks in advance
Best regards
Hans-Peter

Basically, reinstall the Boot Camp video drivers manually and if that doesn't work then go to the AMD/Radeon website and install the Windows drivers directly for your video card model.
If you want to do a search you will find others that have pretty good luck doing it either way.

How can we get Sun Ray DHCP address in Windows XP?

We need the DHCP address (served by Windows) of our Sun Rays as a variable in our Windows XP session (served by VDI 3 / vBox 2.0.10). Customer wants to use this for a windows script which maps the room printer to the Sun Rays Windows XP session. So the user can get always the room printer automatically mapped as the default and don't need to choice the right printer. How can we do this and will this work wor hotdesking too?

currently you can not use SGD and Sun VDI on dual monitors. There is a Request for Feature Enhancement to provide this feature in a future version.

Sun Ray Server x64 or T2?

Hi,
I have been searching around looking for some advice/benchmarking for what hardware is best for Sun Ray servers. My plan is to use the Sun Ray VMware View Connector and so the Sun Ray server will only be managing the sessions rather than providing the desktop.
Therefore, would a T2 system give more consistent performance than a x64 system? and, how many Sun Ray sessions could be expected to be managed by a T5120 or a X4100?
Finally, is running the Sun Ray server in a VM a supported config?
cheers,
Simon.

We have found that x86 series server far out strip the T series boxes for Sun Ray.
A X4100 with 8GB RAM should be able to handle 100 odd sessions. We build for our Customers on a model of around 125 sessions per server. We used to use X4100 but have moved to X4140, if you bumped the RAM on these to 16GB you should get more.
Sun Ray runs poorly under VMware and if you need to go down that route run lots of little Sun Ray servers with no more than 20 odd DTU per server.
Hope this helps

Sun Ray workstations and Server Win2K.

Hi guys,
I wondering if you can help me to figure out how could I configur run Sun Ray sessions from the Server Win2K. I'm using a Server 2000 + Citrix Metaframe on it.
Also I have 2 Sun Ray workstations that linked(by router) to an one small network with the server.
I'll appreciate for any help or suggestions.

I did not have any problems getting my test Sunray server running version 5 to access Citrix. However the issue we are having is getting the credentials passed through with the DOD CACs.

Sun Ray server software and Sun DSEE

I want to have a centralized user administration in the latest sun java 7 directory server. i want to set up the system in that the users of the sun ray thin clients will be authenticated from
the DSEE. Please assist me in how to make this work.

Basically, you Sun Ray server must be an LDAP client: it must be set up so that when logging in, it actually authenticates users against DSEE.
DSEE can be installed on the same host as the Sun Ray server, but it's not a requirement. On the contrary, in such a case, you've got to be
careful in the start order of services at boot time. So the easiest way is to have DSEE and the Sun Ray server on separate machines.
How to configure both servers is explained here: http://download.oracle.com/docs/cd/E18752_01/html/816-4556/ldapsetup-1.html
Or at least, it's a good starting point.

Sun Ray and Tarantella error in DISPLAY

I am facing the same problem.
I installed Tarantella 4.2 on Solaris 9. It worked well. I can open
sessions on both Windows and Unix servers.
But when I installed Sun Ray Server Software the error began to appear
when I connect using Tarantella to Windows servers.
I can login to the web interface and launch X-Applications. But Windows
applications give the error:
"can't read "DISPLAY": no such variable (error = NONE)
ErrCommandExecutionFailed

jhaddad,
1. Do not start sgd from the rc files start it manually after the system has
booted.
2. Change the permissions on the /tmp/X11-unix directory to allow non root
processes to write to it.
3. Change the sgd binary ttaxpe so that its group is set to root and chmod it so
that it has the "set guid" bit set (This means then when it executes it will run
with a group permission of root, which is how the standard Sun Xsun process runs).
Our recommendation would be to use option 3.
