Documentation Updates for Sun Ray Software 5.1 and Sun Ray 3 Series Clients

Sun Ray 3 Series ClientsWe've had some product announcements the past few months and I want to make sure you all remember where to find the latest documentation.

The Sun Ray 3 and Sun Ray 3i clients are now available and you can find out all about their technical specifications and cool environmental stats on the Sun Ray Hardware Information Center.  If you need additional information about these thin clients that you can't find on the site, don't hesitate to ask.

Just this week, we announced the new Sun Ray Software 5.1 release, which has a number of new features aimed at the Windows connector feature (SRWC).  Check out the SRS 5.1 product documentation.

Sharing is Nice: The User Tested USB Redirection List

We all learn at an early age that sharing is the right thing to do.  I get to constantly remind my 3- and 5-year old girls about this very important aspect about being a good person.

How do I get from small kids sharing to the new Sun Ray Software 5 release?  Wait for it...wait for it....

It's another ThinkThin update about the Sun Ray Software wiki!

In my earlier posts, I talked about how you can use the Comment feature on any page to leave feedback. And, I still encourage everyone to keep doing that.

But, since the SRS 5 Early Access releases, we've provided the following User Tested page for all wiki users to share the USB devices they've tested with the new USB redirection feature.

Currently, Sun supports USB redirection for all USB devices that fall within the following device types:  flash drives, printers, scanners, USB-to-serial adapters, and USB-to-parallel adapters.

The USB Redirection User Tested List lets you (the Sun Ray user community) share what devices are working for you, including USB devices not in the supported device type categories.

This page already has over 200 edits and over 100 entries from a number of users. And, I just added a Recent Contributors section that dynamically shows who has made the latest edits to the page.

So, what are you waiting for?  If you are using the USB redirection feature and you want to share the devices you are using with this cool new feature, share away!

SRS 5 Wiki Documentation: Everything is O.K.

Last time I talked to you, I was trying to ease you into the new way we are delivering the Sun Ray Software 5 documentation.  What can I say, I'm a very nurturing person.

Positive Feedback

The good news is that my prediction that everything was going to be o.k. held true.  After going through a vigorous Early Access program (which ended on July 31st), the wiki documentation held its own.  In fact, we actually received the following positive feedback from customers:

  • "I like the new wiki format for documentation."
  • " online documentation is huge improvement"
  • "I relied heavily on the wiki.. certain steps are always tricky during an upgrade and the wiki documents these better."
  • "Again the wiki is cool, but it is hard to find information sometime and customers want pdfs."

Dynamic PDFs

The last feedback brings up a good point about some users still wanting (or needing) PDFs, and I forgot to mention in my last post that we have that covered as well.  On both the SRSS and SRWC documentation sites, you can dynamically build PDFs based on all the information on the wiki.  And, the PDFs will be in sync with the latest content on the wiki.  Here are the specific pages where you can get to the PDFs, and the links to these pages are also provided on the left-hand nav bar on each site:

I know these PDFs are not as slick as what you are used to from Sun, but we are working on that and the output will continue to improve. I'm on it.

Comments, Calling All Comments

Now, even with the positive feedback, there is still room for improvement...there is always room for improvement. We are getting ready for the next Early Access program and we are continuing to improve the content based on reviews and comments.   If you are feeling some post-EA1 blues and want to provide more input to the SRS 5 release, you are in luck.  The wikis are always open for comments and you can make comments on a specific page.

Here's how to provide a comment on the wiki:

  • Log in to
  • Navigate to the page. 
  • Choose Comment from the Add icon.
    The comment section is displayed.
  • Enter your comment. 
  • Click Post.

From our good friends over at the Sun xVM Ops Center team, see the How to comment on a Sun Wiki page screencast for a visual, step-by-step tutorial.

Looking forward to your comments, and I'll be back again soon with some more documentation goodness.

(BTW, if you are wondering why I've included a picture of a koala bear, I don't have a good answer for you.  I like when blogs have pictures and I didn't have one to provide.  So, I thought I would give you a random koala bear picture.  It's hard not to smile when you see one of these marsupials.  Again, I'm all about the nurturing....)

Not Exactly A Sign Of The Apocalypse...

But far bigger news than cats and dogs sleeping together!  I kid, but how cool is this Microsoft Whitepaper on VDI using Sun Rays!

A "USB Drive" daemon for Sun Ray sessions

\*\*\*\* THIS VERSION OF usbdrived IS DEPRECATED - see \*\*\*

A lot of people ask me the age-old question: how can I see thumb drives (and others) attached to my Sun Ray on JDS/CDE/Windows? (it probably works unchanged for SLES and RHEL.)

The inelegant, user-unfriendly solution that is always there for you (JDS/CDE):
Without doing any further work, the answer is quite trivial: SRSS mounts the thumb drive on a non-trivial directory (non-trivial as in "not in your home directory") - namely at:


(mounted disk names and #s appear here)

You can then access this via the file manager - for example, in JDS, (right-click) Launch -> Browse Documents (Nautilus) and point to this directory. Better yet - bookmark this directory under Nautilus as soon as you can!

However, the above is typically unacceptable for customer deployments, and until the time Solaris/JDS can handle this automatically, I've scripted a couple of workarounds. See next section.

The elegant solution: "USB Daemon (usbdrived)"
The following instructions will automate USB drive "show-up" so that when you insert a thumbdrive into your Sun Ray:
1) a file manager window (Nautilus) will automatically open up showing the top-level directory of the USB drive, and
2) a link is created on your desktop, called "USB Drive" (I just couldn't come up with a better name...)

Once you pull the drive out, the above disappear, so it's important to make sure that any copying process is done before pulling it out. (actually, the file manager window disappears only if its on the root level of your USB drive. If anyone can tell me how to close any Nautilus window that's open on sub-directories, please let me know!)

The instructions here also integrate the script with utaction so that disconnected users don't chew up unnecessary Sun Ray server resources.

HOW TO (Basic instructions for JDS):
These instructions assume that you'll install this for your user account. Extrapolate for server-wide deployment as required...

1) If you don't have one, create a bin directory in your home directory
- run this: mkdir $HOME/bin

2) copy usbdrived to your newly created "bin" and give it exec permissions
- run this: chmod +x $HOME/bin/usbdrived


3) If you're running version 1.23 or better of utdiskadm, skip to step 6. To find out, this command will tell you the version number
- run this: head /opt/SUNWut/bin/utdiskadm | grep ident | awk '{ print $4 }'

4) If you're on version 1.22 or lower of utdiskadm you need to patch an 'alternate' version that includes a little fix: copy the standard utdiskadm to your bin directory (call it utdiskadm.fix) and change one line (because, under certain circusmtances, logname returns nothing...) - the script will probe for an up-to-date utdiskadm and ignore yours when the system has been patched as required!
- run this: cp /opt/SUNWut/bin/utdiskadm $HOME/bin/utdiskadm.fix
                vi $HOME/bin/utdiskadm.fix
                find the line UTUSERNAME="`logname`"
                change to UTUSERNAME=$USER
                :wq (save the file ;)

5) If you are \*not\* placing the updated utdiskadm.fix file in your bin directory, update your "usbdrived" script to reflect the location of utdiskadm.fix.

6) add a line to your .profile (bash/ksh/sh) or .login (csh) in your home directory that will enable the daemon on card insertion (change the path accordingly if the script is not in your bin directory)
- run this: echo '/opt/SUNWut/bin/utaction -c  "$HOME/bin/usbdrived start" -d  "$HOME/bin/usbdrived stop" -i &' >> $HOME/.profile   (or .login if csh)

7) Log out, log in... That's it. (or you can run the above line to test as a one-off until you log out).

If your are using CAM/CDE, make sure you edit the script and change the USEJDS variable to 0, so that:
1) Nautilus is not invoked automatically (though you can, but...)
2) The "USB Drive" link is created in the user's home dir and not the Desktop dir, which doesn't exist

You can then add a CAM menu entry to open dtfile on this, such as "Open My USB Drive". You do this anyway without usbdrived by following the earlier section, but it won't open in the exact mount, but rather in the parent folder. These instructions are particularly useful for the next section...

Under Windows
You need to run the daemon like above under either JDS or CDE (whatever it is you are using underneath) and make sure you start up uttsc with the appropriate -r option, e.g. -r disk:U="$HOME/Desktop/USB Drive" for JDS. This will let you browse the U: drive when there is something mounted, and it will allow for changing USB drives without disconnecting your Windows session, as usbdrived depends on utdiskadm to create the "USB Drive" link on demand.

Make sure that if you are using CAM with the Sun Ray Windows Connector, you make USEJDS=0 in the usbdrived script.

This only allows for one USB drived at a time to show up and be managed. That's enough for now ;)
