Thin client with VCL
Hi All, Is anyone here is using a thin client with VCL? I.e. Dell FX100 or similar? (http://en.wikipedia.org/wiki/Thin_client). This could work well with VCL, since most of thin boxes support RDP. Interesting to see how a thin client compares to a regular PC in classroom environment. Seems like this would be a better option - less expensive, less admin overhead, more secure, and with all the benefits of VCL...

Re: Thin client with VCL
Yes I use chippc thin clents, also you can use an IPAD with cloud share a (RDP app) but in this case you have to write the ip address, user and pwd Juan José Zamanillo -Original Message- From: Dmitri Chebotarov Date: Tue, 10 Apr 2012 09:41:11 To: Reply-To: vcl-user@incubator.apache.org Subject: Thin client with VCL Hi All, Is anyone here is using a thin client with VCL?

Re: VIM_SSH failed to login error
Hello,
Welcome! You do not need the vSphere SDK and you don't need to
configure the username/password in the profile. All that is required
is that the management node is able to SSH without a password to both
the VM host and VM. It looks like this is working.
I don't think the problem has to do with your VCL configuration but
seems to be related to VMware. I can't recall seeing the "Failed to
login: vim.fault.NoPermission" error before and was not able to
reproduce it. Can you log in to the VMware web console as root? If
you can login, select the VM host in the Inventory pane and look at
the Permissions tab. Does root have the Administrator role?
Did you install any other VMware products except VMware Server 2.0? I
have seen conflicts before when the vSphere SDK or VIX API was
installed over VMware Server.
At any rate, you'll need to be able to manually run the vmware-vim-cmd
commands before attempting to capture the image with VCL again. When
logged in to the management node shell, do either of these commands
work?:
vmware-vim-cmd hostsvc/datastore/listsummary
ssh -i /etc/vcl/vcl.key alpha-vcl 'vmware-vim-cmd hostsvc/datastore/listsummary'
If neither works, try restarting the vmware service. If the commands
still don't work, try rerunning vmware-config.pl.

Re: Thin client with VCL
Several years ago, we put thin clients (Sun Ray) in all our public computing spaces and computer-equipped classrooms. They work great for most things, and they do indeed save lots of expense and hassle. We're now in the process of going back to PC's, though. There are several reasons, but the one that might apply to other sites is remote display of graphically-intensive applications. 3D rendering is the obvious one, but there are also a few legacy (DOS-era) scientific graphing packages that don't play well with a network-connected display, and the accumulated latency during real-time graphing appears to the user as a drastic slowdown in performance. So, test all your apps thoroughly before you commit. On Tue, Apr 10, 2012 at 09:41:11AM -0400, Dmitri Chebotarov wrote: >Hi All, >Is anyone here is using a thin client with VCL? I.e.

Re: Thin client with VCL
Michael's point about testing is excellent! :-) Other considerations include comparing prices - the price of desktop computer has decreased greatly in the past few years, narrowing the price difference from thin clients. Also consider how you might want to use the desktop/local machines. The VCL is a desktop augmentation setup - so you likely want to use the local machines for web surfing, e-mail, perhaps word processing ..., what else. That decision impacts the price of the thin client. --henry schaffer On Tue, Apr 10, 2012 at 10:59 AM, Michael Jinks wrote: > Several years ago, we put thin clients (Sun Ray) in all our public > computing spaces and computer-equipped classrooms.
