LTSP on EL 6.4

[Burke Almquist]

I've been unable to get LTSP to build on Scientific Linux 6.4. When I go to install ltsp-server (yum install ltsp-server) in cancels saying that it cannot find the 'mock' package, which is a dependency for ltsp-server. Has anyone else been able to install ltsp on CentOS 6.4 or RHEL 6.4?

Hi,
Yes, I was hit by same issue. I just added EPEL repository and this helped with "mock".
EPEL contained somewhat older LTSP, however, upgrading it, or installing from elsewhere should not be an issue.
There are other obstacles to overcome on that particular distro, feel warned.

Thanks Emil, I was able to get it working. Well, I was able to get a client to boot to it anyhow. I haven't tested other things like local storage, but I was able to boot into a useable environment.
Using EPEL instead of the "new" s3 repository worked for me. Maybe the install instructions on the wiki need to be changed again? I didn't need to do bridging, as assigning any network device assigned to 192.168.67.1 will make the networking work correctly. Otherwise I followed the older version of the install instructions from the wiki. No need to mess with turning network on or network manager off since we aren't using the bridge anymore either!

I need to replace my Diskless Workstations T1420 thin client because the Eden
processor is no longer supported ie. will not boot with RHEL 6.5.

1. I am considering going with a Diskless Workstations 1600 or 1700, which uses
an N270 Atom processor, which I would assume is still supported, if they're
advertising it. I am a little hesitant to go with this processor, since it was
released in 2008. It seems likely that support for such an old processor will be
dropped in the near future.

Are there other thin client options to consider? This is a single seat thin
client at home, so price is not really an object. What I am more interested in
is ease of management and performance.

2. Should I assume that any thin client hardware that supports PXE boot will
work with LTSP (obsolescence aside?)

3. My server is a 64-bit machine running RHEL6.5 (Essentially Centos6.5). Would
I be correct in assuming that it would be better to have a 64-bit thin client?
As far as I can tell from the Diskless Workstations web sites, their Atom
processors are 32-bit. I would expect that if I did want to run some
applications as local applications, having a 64-bit TC would be simpler. As
well, 32-bit processors are, let's face it, so 1990's. I would expect a 64-bit
processor to be less subject to the fate of obsolescence that my current TC
succumbed to.

Suggestions for thin clients that are known to work with LTSP, and use recent
processors, would be greatly appreciated.

Brian,

Let me share my experience. Perhaps I don't fit exactly your question, but there is my experience:

Regarding 1.
It depends on what you use thin client. If you execute any application on yout thin client locally (like a fat client) thin client performance is essential. If not, older machines used as a thin client are fine. I use d510 NetTop (with 1 GB of memory) http://www.alibaba.com/showroom/nettop-d510.html, and I can say that it is optimal machine for K12Linux. I bought theses NetTops with no internal HDD. From my poing of view D510 NetTop with K12Linux on CentOS 6.5 x86_64 servrer is optimal solution. NetTop 510 price was $178 including VAT. I prefere NetTops because owing to the NetTop with no HDD I can avoid any operating system license payment. Buying thin client machine you pay for OS placed in flash memory.
Regarding terminal memory my tests showed that d510 machine with activated 5 consoles and 5 users logged in and opened Fireox, Libre/Microsoft Office (Ctrl+Alt+F1 ... Ctrl+Alt+F5 - 2xLDM, 1xXDMCP 1xxfreerdp and 1xrdesktop) used no more than 500 MB of memory. So, for standard office user terminal equipped with 1 GB of memory is OK.

Regarding 2.
My experience says that no. K12Linux thin client images don't support all video cards with full resolution (CentOS and Fedora). You can try to add to the thin client image proper driver/module and to solve this problem (I made it for SIS chipset, but I failed with GeForce). Very important is NIC too. You shoul check is CentOS/Fedora/LTSP support terminal NIC.

Regarding 3.
I use x86_64 servers (CentOS 6.5) and all my LTSP thin clients runs using x86 images and I don't see real reasons to change it (I don't use as a LTSP terminals Intel i3/i5/i7/Xeon machines). LTSP server servs thin image to the terminal and thin client binaries runs on the terminal. So, if thin client image offers the protocols we are at home. Let me add that I tested debian 7 LTSP thin client image with K12Linux server and I can say that terminal works. I admit that I dont't tested all functionality (for example multimedia) with debian 7 thin client image, but in general - it works.

Best regards,
Radek

Marc,

I have presented my experience and my favorite LTSP terminal model (http://www.alibaba.com/showroom/nettop-d510.html). I can add two suggestions:

1) If you have old PC (K6 III CPU, Pentium III CPU, Pentium 4) - use them. Owing to thins you can reach computer learning center for free. For AMD K6 III CPU and Intel Pentium III use i586 binaries for LTSP client (nevertheless for Pentium III 1 GHz and newer Pentium III you can use i686 binaries). For old machines (Pentium II, AMD K6 III please remember that theses michines haven't sound card as a standard equipment.

2) Before purchase test with LTSP selected model.

Best regards,
Radek


Am in Cameroon and i will really appreciate if you advise me on models i can purchase for a Computer learning center.

Thanks

Did K12 is a Linux application or a full OS?

And did somebody succeded to use LTSP on Centos-7 or RHEL7?
