Will Novell Adopt The LTSP Project? 277

SafeTinspector writes "Yesterday I attended a Novell/HP Linux seminer "Delivering & Deploying Linux Across the Enterprise" Among the boring and expected stuff, the Novell representative had several slides in his presentation claiming that Novell is going to get heavily involved with LTSP (Linux Terminal Server Project) to bring policy based security and administration to the LTSP similar to those found in Microsoft and Citrix terminal servers--probably through their venerable Zenworks product line. Also heavily hinted at would be an install wizard provided by Novell that would greatly simplify the installation and configuration of LTSP, which is currently quite complex. I can find no hard information about this on LTSP or Novell websites, nor any information within Google newsgroup search. Does anyone know more about this? On a side note, the laptops of both the HP rep and Novell rep were running SuSE Linux Desktop with Ximian XD2 installed and the presentation was made using OpenOffice Presentation."

    We all like to decry all the networking cruft that X has designed into it, but this kind of participation of a first tier vendor like Novell in redeveloping the X remote terminal service really shows how necessary all that cruft really is.

    It doesn't really explain why they feel the need to reinvent the wheel, but it just goes to show how far Linux has come when it can attract the likes of Novell into its growing ranks of corporate sponsors.

      Sorry but X SUCKS compared to RDP/ICA. I can be quite productive using RDP on a 28.8 dialup line if I turn on bitmap caching and turn down the resolution/bpp. X on the otherhand is almost unusable across a slow DSL line. Multiply this times hundreds or thousands of employees and the bandwidth savings are HUGE. X was great for when it was invented but it doesn't hold a candle to RDP/ICA.

        no, X doesn't suck. it's based on a client/server model when all computing was networked. the computer on every desk mentality eminated in redmond. X works great across networks. in fact, instead of LTSP, i just used a singe X server and had several X clients running in my classroom last year. (i am at a new school this year.) i had a P3/933 w/512MB running 7 X clients, OO.org, moz, etc., without a hiccup. in fact, i had a knoppix boot cd that i could pop into any old box on campus and get X from anywhere. freaked some people out.

The problem with X is that it sends the entire bitmap across every time there is an update, whereas RDP/ICA caches the bitmap and will reuse it, even across sessions. This makes for some heavy network traffic. Add to RDP the advantage of not losing the session because of network or client problems and it's a clear winner. I loved X when I first used

      No, it is because tons of managers that just need IE, Outlook, and Wordpad, opps Word, and Access won't stand it. Managers have to have a scanner, digital camera, video capture cards, and dual monitors. It doesn't matter what they are managing they approve the budget. If it wasn't the manager, it would be the IT guy or the desktop publishing/web guru that needed it. The managers would generally argree that they need to lock down and micromanage all their employees. They want all that on the same platform as all their toys.

      Thin clients should be on almost every business desktop. Other than call centers, I'd doubt that will ever happen. Remember if it was good enough for the manager it is good enough for his sec. or assistant.

      If you are using ssh+x forwarding the client still has to have an operating system.

Both need to boot up a local kernel and minimal userspace, the only difference is that one uses 'X -query' to do an XDMCP request, where the other SSH-es to a server and runs the desktop start script.

    Novell Brewing a New 32-Bit GUI Environment (PC Week)

    >From PC Week for April 25, 1994 by PC Week Staff

    Novell Inc. is developing a low-cost, 32-bit multitasking operating
    environment based on a "freeware" version of Unix that sources said will
    run Windows, DOS, NetWare, and Unix applications.

    Novell is expected to demonstrate the software -- which it is developing
    under tight security at an off-site warehouse -- to a few select users
    at next week's NetWorld+Interop trade show, said sources close to the
    Provo, Utah, company.

    The new system, code-named Expose', is not a derivative of Novell's own
    UnixWare; it is based on Linux, a full-featured Unix clone for PCs that
    is distributed under a free GNU Public License, sources said. Linux 1.0,
    which shipped in March, runs on 386- and 486-based ISA and EISA
    computers.

    Expose' will be based on a graphical X Window System environment called
    Looking Glass, which Novell licensed from Visix Software Inc., of
    Reston, Va. It is expected to use an advanced 3-D desktop metaphor to
    allow users to easily navigate through it, sources said.

    Expose' "is not as much an applications environment as it is a front end
    to many environments, [including] NetWare, Unix, and Windows
    applications," said a source who has been briefed on the project. Users
    also will be able to run Expose' as a front end to the Internet, possibly
    through the Mosaic GUI, sources said.

    Basically, this was a X11 terminal server sort of thing that could also redirect Windows apps. The project was eventually killed, and Ray Noorda picked up the Linux pieces and formed Caldera (later SCO).

    Although thin clients have been around for a few years now, in those days 300 MHz server CPUs and 10 Mbit/sec Ethernet were top-of-affordable-range. And the performance was a bit clunky.

    I'm running Ximian Desktop at home, and I've got a remote X display in a comfortable, sunny room (servers are in the basement). I can definitely attest that full support of LTSP would be a wonderful thing.

    There's lots of talk about Linux desktops replacing Windows desktops, but too many people want to use Linux as a drop-in Windows replacement. That's unfortunate, because to really get the most out of Linux, you have to treat it like Linux -- play up its strengths. The remotability of X11 on a window by window basis (as opposed to the whole desktop, which is how it's done in Windows) is central to this.

    This is, in fact, how the folks in Largo, FL made their system work so well [zdnet.com]. Everything runs from big servers. The nice thing about this model is that you can roll out dedicated servers for various applications. You could have a big box dedicated to OpenOffice, for example. It would run lots of instances of that application (and you get the associated memory footprint savings) being displayed on everyone's desktops. Easy to deploy, too: you just publish the icon or menu item to fire it up, and it executes remotely and transparently. The user doesn't even know that the app is running on a different server -- not even when he/she goes to load and save files, because you're using NIS and NFS to unify the authentication and the document directories across all servers.

    It's a beautiful, beautiful thing. Elegant and seamless. And it's only possible in a Unix/Linux environment -- Microsoft doesn't have anything even close to this. They can't, because it screws up their pricing model. And we all know that money is more important than technology in their world.

    I am currently running 150 desktops off of two servers using thin client deployment. Instead of going with ltsp we use a slackware live cd that gets it's final config from a web server using wget and a php script that passes out configurations based on the sent mac address.

    Finally it just lanches x against the servers using the -query option. This is one hell of a lot simpler than ltsp and we do not have to worry about nfs mounted root or none of that junk.

    The servers are actually redhat AS 3.0 running in clustered mode. Now if redhat would just hurry the up and release GFS I could run a shared /home which would be really cool.

    The gnome guys could also help out greatly by adding the ability to deploy desktop icons to multiple users from say root's desktop. I have scripts to do this but it would be nice to have it

It's kind of hard for me to take you seriously about your commitment to a Linux product line when you're using M$ products. If your company has so few people that are Linux literate that they have to send M$ drones to represent them, how do you expect to produce a native Linux product? I wish them success and hope for the best. But, their failure won't stop me from using my Linux boxen. ;)

    In spite of this, if you want an HP laptop, you have to buy Windows (XP Home). Since their upgrade to XP Pro is $50, about half the retail difference, I suppose you could only expect saving 50% of the retail price of XP Home ($200*50% = $100) if they were to leave it off. While saving $100 would be nice, NOT sending anything t

    If they could work on other enhancements to LTSP or X such as "screen" like session management [uni-klu.ac.at] or vnc session management [sourceforge.net] or load balancing like Citrix.

    I think its greating them getting involved, LTSP is quite a mature project and while I'm not quite sure what kind of extra value they would add hopefully they will be looking at solidifying LDAP/Edirectory integration [pcxperience.org] and other enhancements (like bandwidth optimisation).

    Sometimes it's hard not to kick oneself for being an early adopter. I've been successfully deploying LTSP labs at work [k12.or.us] this year using SuSE 9.0 as a base system, and the project has been a success, but it's been a heck of a lot of work. As we're deploying these as student lab computers in a K12 environment, lockdown is key, so I've had to learn (and make good use of) the KDE Kiosk API [kde.org], and of course this is before the Kiosk admin tool [kde.org] became available. Additionally, we have an Active directory with accounts for all secondary students, so I got to learn how to compile, install, and configure Samba 3 to get winbind to do some of the tricks I needed it to do besides just auth. Also, our primary students don't have an account of their own but rather use a shared school account, and Mozilla has that very annoying profile problem when a user tries to run multiple instances of it, so I had to write a wrapper [k12.or.us] so that it could run sandboxed (which also provides the benefit of keeping the kids from setting bizarre configurations which are then replicated to all the other users as they are wont to do in our other labs).

    All in all, I'm kind of glad I did all this work by hand - I learned a lot, and most of it is now very easy for me to do. On the other hand, had the rumoured deployment tools been available when I started the project, I would have jumped on that and quick. I'm frankly not sure which is better in the long term, but I know it would have been faster to just click'n'run =]

    One last thing - before someone flames me for being stupid and not just using K12LTSP, I have to say I tried it, and didn't like it - for one thing I needed more flexibility than was provided by K12LTSP, especially where AD auth comes in, and besides that, as a matter of preference I like what the KDE Kiosk api provides, and we all know just how much Redhat-based distros Don't Support KDE =] In the end, I got to know the system a lot better, and can do a lot more with it than I would have been able to do under a K12LTSP system. This isn't to disparage the effort and amazing work produced by the K12LTSP team - they really do have an excellent product and I recommend it wholeheartedly for K12 staff needing to get a fast deployment out - it just wasn't the fit I needed for this project.

    Our company [lumensoftware.com] has been been doing LTSP server installs in local area school for a year, now. In that time we've learned a lot about what LTSP needs and doesn't have and have developed tools to deal with those issues. Novell has a long road ahead of them to deal with that list of challenges. Off the top of my head, here are some common ones:

    1. Devices connected to thin clients are extremely difficult to bind back to the server for enumeration and individual user access. Think users in different rooms want to print to their printer on their desk. Our tools handle that but took months to develop.
    2. Managing the KDE Kiosk API to lock down user desktop is not currently possible in anything but config files; again, our tools manage those things but took months to develop.
    3. Managing the rolling out of user profile changes requires scripts and GUI interfaces to those scripts.
    4. Changes in hardware configurations require close relationships with customers where an advanced Linux technician can respond timely. This is a huge cost to our company but it make the stuff work and makes our customers happy.
    5. People that purchase LTSP servers have no interest in learning or administering Linux. They want it to just work; they're tired of adminstering variances in Windows labs and networks. You have to have a Linux tech to closely support the server.
    6. Upgrades between releases of SuSE cannot be done, AFAIK. Presently, the only distros that can continually upgrade without breaking are Gentoo, Debian, LFS, and Slackware. This is Novells biggest challenge. This means that users of Novell's implementation would have to reinstall to receive any new software.
    7. With currently available SuSE tools, it's not possible to boot from CD remotely and do a complete server rebuild or forensics in case of absolute disaster. We can do this by using Gentoo boot CD's.
    8. Clients invariably have one Windows app that they just have to run in Wine. It requires time, patience, and working with the Wine folks and good debugging skills to get some of these things to work. I don't think Novell has the time or interest due to costs of such things.

    Novell has their work cut out for them but I think that, ultimately, a company this large will find that the cost of supporting these servers running in places with noone with any Linux knowledge is too high -- they'll get out of the business or their customers will not get sufficient support and leave.

    ... IMHO, of course.

      Really? I just did a quick lookup in the login script to set the PRINTER environment variable to the right printer depending on the hostname/display (depending on if it was an LTSP terminal or full Linux system). It's a little ugly but dead simple. If

    Mandrake already offers what Novell is now getting around to implement. Look at Mandrake's terminal server, which also does audio and local terminal to floppy file saving through some pretty nifty tricks.
