Re: [Ltsp-discuss] Computer Lab with LTSP
Hello, So I just found out that my school will have to use LTSP over wifi because of costs. I have some questions: How will I do this? Will it be cheaper to use ethernet? What hardware specs do I need?

We have ca. 50 THIN clients (2 labs + some groups and single ones) running on an Intel Xeon system (simplest Xeon CPUs with "only" 4 cores, i. e. 2 real, 2 virtual, so 8 in total), 8 GB RAM, 6 SATA HDs (no RAID).

Re: [Ltsp-discuss] Computer Lab with LTSP
It sounds like your requirements for a switch are minimal. Buy the cheapest, they are all the same at the entry-level. Buy 2 because they are cheap and LTSP will utterly fail if the switch fails. I am not knowledgeable about SSDs, but buying one that exceeds the speed of the SATA controllers in your T40 and T60 (SATA1 1.5gbps as near as I can tell) is probably a waste. You will be better off buying a server with SATA2. http://forums.lenovo.com/t5/T61-and-prior-T-series-ThinkPad/T61-Support-SATA-II/td-p/64464/page/6 On Tue, May 29, 2012 at 7:07 PM, Abraham Close wrote: > Hello, > > Thanks for all of the replies!

I don't think so (so, you should probably do fat clients in your case). If I understand right, your clients are just as powerfull as the intended servers (same machines, right ?). So you should probably not divide the server power between clients which are themselves as powerfull : you will waste clients ressources in this case. By doing fat clients, you still benefit from the centralized setup that LTSP provide (only one installation for whatever clients you have). > And what network switch do you recommend for 20 clients?

I've always found Netgear switches to provide good value for the money. The GS724T is my workhorse, but you might want something with more ports.

Re: [Ltsp-discuss] Computer Lab with LTSP
Fat clients are a good way to go because they take less from a server, however they are more difficult to control in a classroom environment. The new fat client system with 12.04 looks very exciting. https://help.ubuntu.com/community/UbuntuLTSP/ltsp-pnp I think you should check out the cluster server setup for a thin client setup to start off. Yes you need a switch and all the wiring . I have setup quite a few Tuxlabs and have documented it all . Email me at pdk.gmail.com if you are interested.

Re: [Ltsp-discuss] Computer Lab with LTSP
Further on that, you can only PXE boot computers over an Ethernet connection, so it must be connected at all times. You are talking about T40 and T60 laptops, but it will be impossible to make them mobile with LTSP over wireless, you'd need to install the Linux distro to hard disk. Otherwise, if you are running them as fat clients, with a spare one used as an LTSP server, I could see you being able to support 20 clients. Gigabit for fat clients, fast ethernet for thin clients.

Re: [Ltsp-discuss] Computer Lab with LTSP
Jay, 7 clients connected to a server comes from the fact the T60s have a limited amount of computing power to sustain 7 clients. At least thats what I read from a guide by Edubuntu. BTW, thanks for the fast answer. Now my only question now is: how do I connect the clients to a server? I have heard that I need a network switch. Still lost on that subject.

Re: [Ltsp-discuss] Computer Lab with LTSP
Not sure where this '7' number is coming from... But, the way that fat clients work is that they boot the same central root OS from a central server, and execute that OS using local resources. Once a user logs in, the LTSP login manager will automatically mount directories from the central server that are supposed to be persistent, ie if jdoe logs in, /home/jdoe is mounted and the jdoe sees his/her files just like if he/she logs in on any of the LTSP clients, whether fat/thin.
