Re: Solution for school lab just a thought
Hello all. Sergio. Would you mind to contact me offline (maybe some people in the list won't be interested) I help communities and non profit (very poor) organizations here and would like to know more about your schema and results. Here also we get donattions of hardware. The old 386 and so, computers that big companies do not use anymore and with that we have to work. We are also trying to giving the kids a chance to learn something else so they can compete in a hard job market.

[OFFTOPIC] Solution for school lab
Hi, I am about to setup a small PC lab for teaching operating systems. Since computers will need to be used for teaching Windows/Unix(FreeBsd)/Linux(Novell) I need to find a way: 1. Systems to coexists on the same hardware 2. Easily restore system images to the initial state. I do not want we to turn into Windows only lab.I was thinking in for some Citrix solutions but I wonder if there is other way we can accomplish this task. Thanks in advance.

Solution for school lab
I use a solution that is: 1) a large Freebsd box (phenon X4,8Gb of memory, 1TB disk) 2) OS=Freebsd 8.2 with all gnome2.32 installed 3) Virtualbox 10.x installed in FreeBSD 4) NT 2003 server with unlimited number of users on rdp (the iso is in internet or torrent). 5) internet connection Here this would cost about US$400 Install the system using zfs, insert all users can hold about 1000 users Setup FreeBSD to boot diskless (and so will run on all the old machines in your place) using either pxe or custom CD. The users will use Gnome interface, and those who wants windows, can use via rdesktop, pointing on the NT server on the same machine. You will need a swith with ONE gigabit port, and the others is 100Mbits... This setup you have: about 1200 applictions (from the FreBSDports), some include: java, eclipse, python, c, c++, multimedia, web browing, office, printing, email, chat, calculator, vector drawing, dia (visio), raster image editor (gimp), monodevelop(.NET devel framework), sql (postgresql), sql administration (pgadmin3).

Re: Solution for school lab
Consider installing VMWare ESXi and instances of whatever operating system you like. We have template operating systems we copy to new/replacement instances. You can export your disks to the instances but with all things you gain some, you loose some. with the small machine (phenon 4, 8Gb), and vmware, the sistems is slow... and the MB does not accept more than 8GB. Besides I would need a version of each operating system for VMWARE.. and I do not know if vmware can be used for free. If even in a school you can, in other places you cannot, so I would cope with several platforms... Here I run a business based on FreeBSD, and the less different solutions the better... As someone else mentioned, consider netboot. The booted instance can do whatever they want to your hardware but disks are likely to have to be re-initialized each time, which is fine if you are using disks for swap and other temporary things. I use PXE because it is in the firmware of the MB... (almost always have)... some very old computers, does not boot anything but: floppy, cd, or HD... I choose CD.. one CD, boot all machines... Netboot is great too... With regard to VirtualBox, someone needs to fix it (probably just update the port). The network driver (IIRC) eats memory. Strange I have been using it in a day basis, and never had problems with that... the machine sometimes suffer power failure (3 months, or 1 month period).. I use FreeBSD 8.2 in zfs... with zmirror, and daylly snapshots... so I can go back anything till 5 days ago... Anyway, thanks for the information [] Sergio ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Easily restore system images to the initial state. 1) A very robust if slightly more expensive way is a separate disk for each OS. Many more recent (last 3 or 4 years?) motherboards have an option during POST to choose a boot device so you don't need to go into the BIOS setup screens. This system has the advantage that OS's are completely separate from each other. 2) Clonezilla. (Not very relevant aside... Back in the day of pentium 1's and 2 dual channel IDE controllers I solved this same problem with 3 hard disks, each set to be master, on a home made IDE cable with an extra connector so the three disks were plugged into the primary controller, and a 3 position rotary switch so only one disk would power up at a time. It took a bit of experimentation to find three disks that could coexist but it worked really well as long as one didn't switch over while the machine was on. I think I had FreeBSD, Windows and Netware).
