Hello, i am a long term LSTP user but new to ubuntu and to this list. Hopefully we got the right decision to change to edubunt's LTSP 5. Thanks in advance to the people affiliating LTSP to a distribution. You are doing a great job!

Irrespective of the possibility to make beta tests, we made the experience that even small system changes can affect the production use - say the classroom users. Therefore we decided to have redundant systems. As a school with 80 terminals for more than 800 students it is a must to have redundancy. Otherwise no changes can be made outside periods of holidays. Actually we use three secondary servers for xdm plus one of two servers as main server with the LTSP 4.2. for pxe, tftpboot, nfs, nis, cups and other services. The second main server usually is in standby in case of hardware damage of the first one. If one of the secondary servers failes, the other two will take over the sessions. The second main server and one of the three secondary servers actually are used to setup the LTSP 5 system. Main issues for changing from LTSP 4.2 to LTSP 5 are use of usb sticks and sound on the terminals. Experiments with Opensuse and kiwi-ltsp were not successful. We hope that edubuntu 8.04 now is the best choice. We had some problems with the installation on amd64 server with i386 clients: The installation of the packet ltsp-client-core failed because the file /etc/ltsp_chroot is missed. Finally we got the system running. But we are not sufficient with the clients yet. There is still some work of finetuning to do before we can switch over from testing to production. One problem is performance. Login is somewhat slow but acceptable. The windows on the client behave different: terminal windows react quickly, but other windows, e.g. from open office or firefox are slow. I did not observe this on LTSP 4.2. Could it be an effect of ssh on clients with small cpus? -- Kai Wollweber Integrierte Gesamtschule Eckernförde -- edubuntu-users mailing list [email protected] Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/edubuntu-users
