Next Knoppix Release to Feature GPL'd FreeNX
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."
But an F/OSS hacker has taken a company's proprietary work and made it available for free, even giving it a similar name.
Why is this a good thing?
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 which could cause a company (and a lot of potential Linux users) to go out of business.
How are the developers supposed to feed their children if they're unemployed?
How's NX any different/better? When it first came out, I gave it a look but didn't think speed was overly impressive...
In my case Knoppix-STD has been awesome! It's allowed me to play with wireless security tools that I had previously had a bitch of a time trying to configure in a standard Linux Distro. No driver fiddling, no recompiling, no patches, no hair pulling! i fire up Knoppix-STD, plug ni my Lucent card, run an applet to configure my wireless, and away I go with Kismet, Airsnort, Wallenreiter (sp?), Airtraf, and other tools like Ethereal. Knoppix has allowed me, a Windows user, to experience and get accustomed to Linux without having to worry about hosing a drive or sweating arcane drivers issues. If I screw something up or get lost I can simply reboot and be back to square one with no damage done. as soon as I figure out how to mount a USB FOB and install my own apps on it etc. I'll be well on my way to moving a Linux partition onto my HD full time :-)

IMO, Knoppix provides a terrific way to introduce people to Linux. You can also use it to (more) securely surf on strange computers if you want. I see someone has linked to soemthing called Gnoppix below this - I'll be checking that out next! Live Distros rock!

I've found it to be a nice tool for "caulking up" holes in many ways. So far at my research/computer scientist job, I've used it to fix a windows machine (dd, repartition, fiddle a few files) and, more interestingly, run numerical-computation intensive linux applications on the new, faster (winXP pro) management computers, many of which were sitting idle.
:( I am presently mulching up a USB memory stick as my home directory.
The Quantian variant is very good for the latter; it has almost all of the basic GNU sci/math software: R, gnuplot, octave, &c. set up and ready to "just work". It also has some built-in cluster support; drop-and-churn clustering for numerical computations sounds pretty nice, though I haven't tried that yet.
Unfortunately, the NTFS support is poor. This is probably for legal reasons rather than bona-fide technical ones.
Like anything else, it depends upon what you're trying to do and how much performance you need/want.
Me, I use TightVNC over a VPN tunnel (cable modem) and it has acceptable performance. I do pay a performance hit when I use a graphical program such as a place & route tool (I'm an ASIC engineer) but it's by no means unusable.
Of course, I have been forced to use that same place & route tool over a 128Kbit ISDN line (years ago) so I'm quite pleased with what VNC allows me to do, both in terms of speed but more importantly in terms of freedom. When you do ASIC layout work for a living, you sacrifice a lot of family time if you can't detach/reattach ala VNC. So I'm pretty damned thankful.
That's not to say I don't welcome new applications if they better meet my needs. I'll be delighted to learn more about what NX offers just as soon as I can actually visit the proferred links!

You don't use science to show that you're right, you use science to become right.
NX is about networking - high latency/long distance(many hops) - are enough to run X applications.
....
Printing support. Connect to remote NX server - and print on your local printer.
Multimedia support - launch xmms remotely and hear the sound in your headphones
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.

Do you changes clothes while making the "chee-chee-cha-cha-choh" transformation sound?
argh I forgot to mention the disk shareing - so you export your local disk/home directory to the remote server trough SMB that is encapsulated in NX protocol and here it comes - you can use your files on remote server copy them/edit them and do whatever you want in secure way without the need to scp every few minutes.
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?

It is also a good place to start if you want more graphics in a gentoo install. Knoppix sometimes find hardware better then the gentoo install CD and it has all that is needed to install it. Which of course is basically nothing if you have a net connection.
Hmm. I was also trying to RTFA to see WTF freeNX is, but it seems as though ALL the links are slashdotted except for the kalyxo page which didn't seem to mention it.
I agree 100% that articles should give a very brief overview (hell - a one liner would be enough) so interested people can do more reading. Without the overview we have no f-ing clue what the article is talking about. Oh yeah, a google for freenx only comes up with 2 links for porn and an intro to Linux. No help there.
I'm sorry, no. Gnoppix is for some idiotic reason based on debian stable. 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. I honestly don't know how the gnoppix folks are compensating for this with hardware detection and all. Also, I know gnoppix has modern gnome packages, but they're backports, which makes them different from debian testing by default, and it's just one more variable to debug. There's really no point in basing a bootcd on stable; it's like basing a bootcd on RHEL.
