Firefox remote command in Sun Ray

Hi all,
I'm trying to solve a problem in a Sun Ray environment. Our program has to use firefox remote to launch a new browser window in addition to an already opened browser window.
But it does not work. No new browser window is opened. Here is output from the standalone build of remote.c (from original Netscape remote control source) as a test program.
% ./firefox-remote -remote 'openURL(http://www.sun.com,new-window)'
firefox-remote: warning: expected version 1.1 but found version
5.1 (0xc80049) instead.
firefox-remote: (writing MOZILLALOCK "pid63258@xavsun" to 0xc80049)
firefox-remote: (writing MOZILLACOMMAND "openURL(http://www.sun.com,new-window)" to 0xc80049)
firefox-remote: (server 0xc80049 has accepted MOZILLACOMMAND.)
2147500037firefox-remote: (server sent MOZILLARESPONSE "500 command not parseable" to 0xc80049.)
But it works fine if issuing the following command:
% firefox -remote 'openURL(http://www.sun.com,new-window)'
Also our program and this test program work fine in Sun Blade workstation.
Is there anybody who has experienced this or has some idea what's going on here?
Thanks a lot for your help.

I solved it in kiosk mode adding my locale to the option Locale like this:
es-ES

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 1 with remote desktop on windows 7 ultimate

I have a windows 7 ultimate box. I have an unopened Sun Ray 1. Before I open the box, I want to know if I can use the Sun Ray 1 to connect to my windows 7 ultimate box. If I can, how do I do it? Is it easy?
Thanks

No. Sun Rays are truly thin, meaning there is no OS or clients installed on the device. You need a server to use it.

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.

Wed, 27 Jan 2010 09:34:47 -0800
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
#!/bin/sh

Sun Ray error when connecting to Oracle VDI - No Kiosk Sessions Available

When the Sun Ray DTUs go to connect to the Oracle VDI cluster at times they will throw the error "Error starting Kiosk session: No Kiosk accounts configured." We have tried going through the steps to confirm that the Kiosk sessions are configured on the two secondary hosts but the problem persists. When the Sun Ray DTUs do connect they will work for a while and then when left idle for a period of time will loose their connection and be unable to restart the connection with the error mentioned. The Screen Blanking option on the Sun Ray DTUs is set to "0" to prevent them from going into power-save mode but this makes no difference. The Sun Ray DTUs are all updated with the latest GUI firmware and there are no custom options set in the Sun Ray Session Servers.
The thing that bothers me the most is I have not seen any error messages in the logs. I will post up the logs as links in a follow-up post.
Has anyone had any similar issues while connecting with a Sun Ray DTU?
Currently we are running Oracle VDI 3.2.1 on the cluster.
Here are the commands we used to reset the Sun Ray Kiosk accounts:
# /opt/SUNWkio/bin/kioskstatus -c
# /opt/SUNWkio/bin/kioskuseradm status
# /opt/SUNWkio/bin/kioskuseradm delete
# /opt/SUNWkio/bin/kioskuseradm create -l utku -g utkiosk -i auto -u –c

Sun Ray 2 Screen Resolution with 16:9 Monitor

Dear All,
I'm afraid I haven't done anything with the Sun Ray servers for a while and am a little rusty. We're running SRSS 4.2 with SRWC 2.2.
A user has purchased a 23-inch 16:9 monitor whose native resolution is 1280x720, however, this is not listed as an option when I run utresdef. What is the best way to go about making this available please?
Many thanks.
Chris

Anyway, what you're seeing is the expected behaviour. The Sun Ray 3i has only one, fixed resolution. That's 1920x1080. If you hotdesk an existing, smaller desktop to a Sun Ray 3i then that desktop will occupy only a portion of the 3i's screen.
If you're using the latest Sun Ray software you can use the 'xrandr' command to resize the desktop. If you want to do this then you must make sure that the desktop is initially created with the largest dimensions that you will need during the lifetime of the desktop. In this case it sounds like that will be 1920x1080. Use 'utxconfig' to set the desktop to start with these dimensions. Then when the desktop is displayed on a smaller monitor you can 'xrandr' its size down to fit the monitor -- or you can leave the desktop at its full size and let the Sun Ray automatically pan to show the region where the mouse pointer is.
The "Resize and Rotate" X extension (which is what 'xrandr' uses) is relatively new and some applications don't understand it, so depending on what applications you're running you might see some strange behaviour when you use it.

Redirecting Sun Ray sessions

Apparently I have to update my Sun Ray Server to 4.2 or at least apply some patches so that i can recieve audiio to my 2fs DTU's. I do not have a lab environment so I am wanting to move all of my users over to one server.
According to the doc's, I can do a UTSELECT cmd from the command line on the DTU and choose my server, however I don't know how to get to the command line on the DTU. Is there another way I can move/migrate all of the users off of one server without interupting? Is there a 'maintenance' mode I can put the server in or perhaps shutdown a service without hurting the users.
Thanks in advance!!
Jake

First you have to use the GUI Firmware, then you can set manually the network details via Pop-up GUI.

Sun Ray connector interface is invalid

I think I have some kind of configuration problem with my Sun Ray server. When I try to run the utadm -A "I.P. address" command, it comes up at the end with a message about the "Sun Ray connector interface is invalid" or something like that. The problem seems to be with this because the Sun Ray server will not update the firmware on the Sun Ray Clients. Even using the utfwadm -A -e "MAC address" to force an update it just sets it up in the dhtptab.conf file with the macro to download the firmware but when I power cycle the Sun Ray client it does not update the firmware. The only thing I can think of is that it must have something to do with the "Sun Ray connector interface is invalid" error that is preventing it from updating.
The DHCP server will also not update the "LeaseTime" nor the "LeaseNeg" options that I have configured.
Can someone tell me how to get rid of the "Sun Ray connector interface is invalid" error and/or if this might be what is preventing my firmware updates to my Sun Ray clients?
Thanks,

Is Sun Ray a suitable solution for system administrators?

My company is deciding if Sun Ray can be a viable solution for system administrators for additional level of security since Sun Ray clients are diskless...less worries about malware or virus...etc.
However, looking through Sun's available thin client machines, there is no selection of laptop form. As you can guess, sysadmins are mostly remote and on the go...it cannot be expected that they are always at their desks or homes to access the thin client machines. I understand the availability of the web client solution...however, have my doubts about that and how much would sysadmins actually embrace it.
On the other hand, the inability of copy & paste as they are currently doing with traditional thick clients can be problematic too. One use case is when they test and build config on their desktops (say notepad), then upload to server hosts...or opposite, when they need to download logs to their machines and investigate...
I am not going into questions about support of OS X and other tools sysadmins usually use...since the support of true remote access will be the biggest hurdle up front.
Any comments?

Hmmm. Very late to this conversation, but couldn't help to throw some change into the hat.
For casual use of light-weight, non-power hungry applications, running apps via SGD over a Sun Ray (soft client or not) is probably ok. But if you were to try to do this for normal users who need PC-like performance, you'd be delusional. Display information will travel over the network 3 times and you can't take advantage of any of the new, faster graphics capabilities of the newer Sun Ray's when you introduce SGD as the means to access Windows desktop applications.
To be explicit:
Sun-Ray -> Sun Ray Server uses ALP.
Sun Ray Server -> SGD uses AIP.
SGD Server -> Windows Server uses RDP.
If you deploy this widely, better go buy some stock in Cisco.
I'd use SGD only for remote PC/Mac/Unix users who need to bounce in from the wild west.
I'd use Sun Ray -> Sun Ray Servers + Windows connector (uttsc) for thin client access.

27D error on Sun Ray client

My Sun Ray setup was working before i tried to reconfigure the Admin Gui. Once the GUI changes were added i rebooted the server and the clients would not come up. Instead of booting, they display a 27D error along with an hourglass and a DHCP address. Can someone please tell me how to get them running again. Thanks.

Not to throw this way off tangent, but is the "requirement" for Internet Exploiter ... er ... Exploder ... er ... that MS security hole ... {grumble} ... is it technical or "just because"? As long as the page doesn't use ActiveX or other MS-proprietary code, it should run fine under Firefox or Mozilla.

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.)
