Package: ltsp-main Version: Skolelinux 2.0r1 The problem:
A lot of schools that has upgraded from Skolelinux 1.0 to Skolelinux/DebianEdu 2.0 and lost the support for thin clients on 50% machines. This is on reused machines from 1996 with 32 MB RAM. In the Municipality of Nittedal we talk about 250 machines. The reason for this is the disabling of swap in the new LTSP solution that comes with Skolelinux/DebianEdu 2.0. In Skolelinux 1.0 the default was swap on the thin clients over the network file system. Some have suggested to upgrade the hardware to use 64 MB RAM. But for Nittedal it's not an option to use 38.000 EURO extra baying 250 reused PC's that replaces the machines that has 32 MB RAM. The Municipality in Nittedal don't have the manpower to put in extra RAM. The persons that maintain the machines at schools just have 1-2 hours a week to do technical support on 50-100 clients. Because of the scarce resources the "swap not turned on" problem gives bad publicity for DebianEdu when the schools "loses" a lot of clients. Sugestions: There are three different solutions that I can think of to handle the "swap not turned on" problem, but just one that takes into account that Skolelinux 2.0 uses the next ltsp-solution: 1. Downgrade to the LTSP to 4.1 or 4.2 with the SWAP over NFS solution (To use Skolelinux 2.0 pr05 could be a solution) 2. Replace the LTSP beta 5.0 and use Lessdisks 3. Turn on the Network Block Device (NBD) in the configuration on LTSP 5.0. (This is on the TODO-list from Petter Reinholdtsen) http://wiki.ltsp.org/twiki/bin/view/Ltsp/SwapNbd#Configuring_Swap_over_NBD_in_LTS http://developer.skolelinux.no/~pere/bzr-archives/ltsp-main/TODO When it comes to diskless workstations schools has experienced the application freezes the whole desktop. e.g by using the spell-checker that underlines misspelled words with a reed line. The problem evaporates when turning swap on the diskless workstations. So also the diskless workstations should have the swap turned on as default. It's also important that the maintenance person at every schools don't get any trouble or hassle when configuring swap. It should work out of the box. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
