Next Knoppix Release to Feature GPL'd FreeNX 238

linuxtag-reporter writes "The first day of LinuxTag, Europe's biggest Free Software event (expecting 25,000 visitors) already has one big highlight. It seems that Fabian Franz from the Knoppix Project hacked up a 'FreeNX Server' based on NoMachine's NX technology (poor NoMachine might lose business now). Fabian Franz presented a first preview of the 'GPL Edition' in a live demo together with Kurt Pfeifle. The demo showed sessions going from Germany to Italy just based on a slow WLAN connectivity (shared with hundreds of visitors). A connection lost due to bad network conditions was easily re-connected to, and a deliberately suspended session was revitalized too -- it was just like 'screen' with a GUI! A report on the official LinuxTag webpage says FreeNX will be publically released for the first time as part of the upcoming Knoppix-3.6 release. The Kalyxo project is building and hosting Debian packages of FreeNX and NX/GPL for everyone to use."

      From the manpage for screen:

      "Screen is a full-screen window manager that multiplexes a
      physical terminal between several processes (typically
      interactive shells)."

      I use it all the time; start an interactive job while I'm at work on a particular machine using screen, disconnect using "CTRL-A d" then go home, log into the same machine, issue the command "screen -r" and I'm right back into that shell session.

      These days, I mostly use TightVNC [tightvnc.com] over a VPN pipe instead, which gives me the graphical equivalent of this.

      Hope this helps.

      Heh, you obviously don't understand the point of Free software. In general, having that product available as Free software will attract much more users than the few at that particular company that might go out of business. If they are -smart-, they will assist the open source development effort, and re-tailor their business to provide expert integration solutions of FreeNX, etc.

      As far as I remember, NoMachine's NX software is based on GPL code, which means they had no choice but to release the source code.

      I remember trying to build it from source when it first came out, but it proved rather tricky. It's nice that someone's now put in the time to make an easy-to-compile distribution of it.

      If I understand correctly, (s)he only took their Free work. The core of the NoMachine product is GPL.

      and made it available for free ... Why is this a good thing?

      Speaking strictly from a capitalist standpoint, it is good because it reduces the cost to businesses that wish to use this technology. Similarly, the freeness of HTTP software (client and server) has been a great boon to corporations that wish to provide easy access to information about their product lines. This has in turn lead to consumers making more informed decisions, which is one of the keystones of free market capitalism. (that's just the good part, in response to your question, see below for a look at the bad part)

      even giving it a similar name.

      The similarity in the name is the "NX" part. I believe NX is a Free protocol. This is much like referring to both Sendmail and Postfix as SMTP engines.

      If F/OSS developers want to speed up Linux, the corporate environment is where they should be looking. By doing this they have enabled corporations to get something for free

      Very well said. This statemtnt (which clearly supports FLOSS) seems to be in contrast to the rest of your post.

      which could cause a company (and a lot of potential Linux users) to go out of business.

      All competition has this effect, whether from proprietary or Free sources. Are Chevrolet and Ford evil because they caused Yugo to go out of business?

      How are the developers supposed to feed their children if they're unemployed?

      They can't. But this makes a leap from "FreeNX removed or reduced the ability to charge twice for solving a problem once" to "developers will be unemployed." That is a spurious leap. The ideal situation, from an economic standpoint, would be for each solution to each problem to be developed once, and the development effort compensated once, freeing the development resource to move on to the next problem. The increased pool of available software labour resources would reduce the time delay businesses incur in solving their information problems, but does not necessarily reduce the time value of solving any given problem the first time. If we begin to approach software development as a temporally-oriented problem solving service, one cannot accurately predict the effect on the wages paid - the economic shift is too great to predict the result on the supply side - but the demand side will be very happy indeed.

      We have not yet developed the economic models to make this a practical reality yet, but with FLOSS operating in tension with proprietary software, the economic stage has been set. This is the typical first stage in every major economic advancement - new technology, in this case zero cost reproduction of information, makes new economic models possible. The shift to the implementation of those new economic models must necessarily occur after the technological advancement, and so a period of market inefficiency occurs. It's not a bad thing, any more than Ford's assembly line was bad for Daimler Benz.

      As with everything in life the hardest part is the first step. Getting users to play with this Linux thing is much easier with Knoppix. People who I interact with all the time, but never wished to try Linux were willing to give Knoppix a try. Ok so maybe they don't switch the next day, but a month later when they need a tool that they saw in Knoppix they give it another whirl or when someone else talks about Linux they think... "Yah I used that, it wasn't hard... I like Linux". Maybe when they get an extra computer they decide to load Linux on it. All because you gave them a Knoppix disk.

      It is a great simple way to let management play with Linux too. Where in the management world of MSOutlook and MSProject they can't load Linux on their box, but they can give Knoppix a whirl on *their* box and play with it on their own. Then when you want to use Linux for your next project they are more likely to let you because it is something they have used and doesn't seem so foreign.

      It might surprise you the number of people who want to play around with Linux, but just haven't yet. I put up a small note that I was giving away Knoppix disks for free at work. I have given away (averaging two) a day for the last month. Try it at your work and see what happens. You might be surprised at whom is interested in playing with Linux.

I run debian stable as a sysadmin on old workhorse machines which are used primarily as servers (including command-line timesharing, so not just "invisible" machines). I can't stand running it more than a year after its typical release on a desktop -- the linux desktop is moving fast and woody already lacks a lot of hardware support.

        • Uhhhh.... You are using X11 over a remote ssh tunnel to "locally" view a VNC session. (i.e., VNC client and server are running on the same machine.) This is not the best use of VNC, and in fact the ONLY benefit you get from using VNC in that case is reconnectability.

      • use x0rfbserver instead. it lets you connect to an existing X session with VNC, instead of having to spawn a new Xvnc session from vncserver.

        It's available as part of a Dag Wieers RPM [wieers.com], so if you're running Red Hat or Fedora Core you're set. And of course the source is a google away.

    • It's far faster than VNC -- think how X runs over a 100mbit network except over, NX gives that performance over a 1.5mbit DSL connection. It is still tolerable at 56k (more so than VNC, in my own experience).

      (By the way, it is actually just connecting to your X server with nxproxy over an SSH link.)

    • Because it uses protocol specific compression and caches, it's much faster than using simply ssh compression (which knows nothing about what it's carrying).

      You can read about it on the NX website.
    • As I understand it, NX probably won't give you a huge improvement over compressed ssh on a local network. The big gains come in high latency networks (e.g. internet), as the NX server can eliminate a lot of expensive and unnecessary delays due to X11 round-trips.

    ...when it was called Citrix.
    • ... when it was called X Window System.

      I'm not sure if any multiuser graphical windows systems preceded X, I'm not old enough to remember.

      Citrix took the X foundation and added useful features like local file and printer sharing.

    There was nice article about the NX:

  • Is it a sad day when the papers linked to on slashdot are no more credible than the comments posted in reply to them?
  • In thier 3.4 release they had integrated wine (perhaps even before that, but they made it fairly obvious in 3.4), unfortunately it doesn't work. Even after countless configuration attempts it seems like a flawed addition to the distro.

    Its something I was looking forward to aswell...

    Just to clear things up, this is no problem for NoMachine at all -- NoMachine has released the core components as GPL -- the only non-GPL parts of NX are the client software GUI,, which simplifies the setup of basically (under Windows) cygwin ssh + X + nxproxy, and under Linux, just a GUI for ssh+ X + nxproxy.

    NX is even mildly supportive of an open-source complete solution -- on the source download page (their site is ./'ed right now) it clearly says something to the effect that they expect a community-created packages will be assembled.

    It's not obvious from what I've been able to connect to so far that isn't slashdotted as to whether you can connect to a Windows box from a Linux box (the orangecrate.com article linked further down shows a connection going from a windows box to a linux box)

    That's actually 2 questions, though - "Does the technology support it" AND "does the LICENSE allow it?"

    I'm assuming that the technical capability is there (just as it is in VNC)...

    Last time I saw the EULA for a recent Windows version I saw in infamous "you may not connect with 3rd-party tools" clause in the license. Is that still there? Is using FreeNX (or VNC or anything else) to connect to a windows box remotely still a violation of the license?

  • I was reading about NX a few months ago and saw that someone is writing a NX-extension for X11 so you can just ssh to a box, set DISPLAY to something like "nx/192.168.0.1:0,port=6789,ssl=1" and run single applications using the NX protocol, MUCH MUCH faster than plain old remote X. It also enables you to "take over" an existing session. It requires that the extension is enabled on both X-servers. Unfortunatly their site is currently slashdotted so I can't find a link..

    I wonder how this affects the proposed KDE/NX integration supposedly under development by Aaron Seigo? If you'll remember, this was mentioned way back in December [kdenews.org] in response to UserLinux shipping Gnome, but I haven't heard anything about it since... let's hope this FreeNX is desktop-independent.

    For those still mystified as to what NX is, it is essentially X11 tunneled through SSH, with some clever caching to drastically limit the number of connections an X server/client need to make, to make the connection feel much quicker.

    untechnical explanation: Normally a remote X session will have to make many hundreds/thousands of trips between the server and client, but NX uses a cache at both ends, only making the most necessary trips, and usually just sending a diff of the changes rather than the whole stream of data. (roughly speaking, of course, as I have absolutely no idea what I am talking about.)
