    whenever attempting to get FreeNX working, i've found it to be a total bitch, client-side as well as server-side. by contrast, rdesktop or any other RDP client, client-side and xrdp server-side (which is purely a matter of apt-get install xrdp on debian-based distributions) is so simple to install that a monkey could do it. demo of a monkey (myself) doing exactly that: http://www.youtube.com/watch?v=nbsydsar5Pk [youtube.com]

    • Couldn't agree more. I've tried to setup NX a couple of times and every time I ended up using RDP, VNC or a Xnest solution instead.

      But perhaps the problems with FreeNX is due to the fact that NoMachine also has a commercial version that they want to push.

      I've had the opposite experience. I installed FreeNX on a VM at the office to provide remote desktops to my users. I didn't have any trouble at all setting it up (Kubuntu 9.10), and had it up and running in 15 minutes.

      I had not heard of xrdp before. I'll have to look into it. One of the 'problems' with NX is requiring the user to install the NX client on their machine at home. Maybe if I switch I can eliminate that issue. Although I kind of doubt it's as bandwidth efficient and responsive as NX. Even remote

    • FreeNX is a bitch to set up, I agree. I've never got it to work properly.

      However, NoMachine's free NX server (which allows up to two logged in users...) have mostly been extemely easy to set up (download packages, dpkg -i *.deb), and performance is in a completely different world than RDP, even win7's. Even on a 30-40 kbps connection I can sometimes forget I'm sitting remotely, because of the speed and response. Try that with RDP, every time you scroll or move something, things just stop. And god forbid you

      • What about sound?

        Once of the nice features of RDP is transmission of sound from your computer so I can, for example, listen to my voicemail when remoted into my office computer. Does FreeNX support that?

        • FreeNX? Not sure, don't think so. NX Free? Yes :)

          (yes, I know it's a bit confusing. NX Free is NoMachine closed source client with max limit of two connections, FreeNX is the open source server)

      Checking the EC2 pricing scheme:

      Small Linux install: $.085 per hour
      Up to the First 10TB of data transfer: 0.15 per GB

      And it goes down as you add more instances in. So the cost may be relatively small.

      But I wonder, if you are remoting to this machine, won't you be charged for twice the bandwidth if you are using it as your desktop to surf the web? Incoming data has to go to that instance first and then route to you. AFAIK you'll be charged for total bandwidth usage.

        Twice?! Haha. No.

        Try 10X or so.

        HTML and optimized compressed images are far, far smaller than an un-optimized, on-the-fly compressed X11 display. NX does a good job, but no way are you anywhere near just double the bandwidth. And YouTube? Forget it!

        And let's remember, not only are you paying Amazon twice, you're also paying that much more for your own broadband connection.

      • But I wonder, if you are remoting to this machine, won't you be charged for twice the bandwidth if you are using it as your desktop to surf the web?

        Why would you use the remote system for surfing the web? I can see using it to test a web page under Ubuntu if your normal desktop environment isn't Ubuntu, but since you need a local computer to connect to the remote one in the first place, and most computers will be more than capable of surfing the web, why would you do normal surfing on the remote?

          Yes I would agree with that. I was just trying to point out the costs associated with I/O bandwidth and wondering if anyone has worked out the cost of hosting a working desktop instance in the cloud, regardless of intended use. Requiring an OS to host the remote desktop application kind of moots the advantages of the cloud for personal use. For multi-user use though, this implementation may work quite well.

        The more interesting use case is probably to be found when you combine the existence of this project with the existence of Eucalyptus [eucalyptus.com] which somebody mentioned above. The fact that it works with EC2 is interesting; but paying Amazon is likely not cost effective(since demand for desktop seats tends not to fluctuate nearly as fast as some server loads do and is, in any case, constrained by the number of NX capable thin clients available) a service where you pay extra for the elasticity isn't obviously sensible

        Bonus: if the nettop/netbook is stolen, NO data is lost, as it never leaves our servers (in persistent form, at least).

      Nope. What it is is the natural end-point after 10 years of outsourcing. When you get rid of the growth path for technical resources, eventually you get a profound lack of availability of senior technical resources. At that point you have no choice but to push everything IT-related out to external vendors because you can't hire internal resources to do it (or even just to manage the process) and must rely on external vendors who can maximize use of those types of resources across multiple clients. However you also no longer have the skills available to know if the vendor is taking you to the cleaners, or cutting corners on management/security to raise profits and significantly putting your data at risk. I wouldn't be surprised if there's a Madoff-level disaster with a "cloud" provider sometime in the next 10 years.
