Root server provide boot image > to clients and application servers provide the applications to the > clients.(after login) Yes. That is because of "ldm-server"-package you install in every application server. And because of root servers setup (lts.conf and get_hosts). root@debian-app-01:~# dpkg -l | grep ldm ii ldm-server 2:2.2.11-2 all server components for LTSP display manager In application servers there are nothing more LTSP related pacages. Root server gives ip address (DHCPD) to the thin client and kernel (TFTPD) and access to the chroot directory (NFS). Sep 5 18:03:08 debian-ltsp dhcpd: DHCPOFFER on 192.168.0.202 to 08:00:27:cc:7a:ab via eth0 Sep 5 18:03:21 debian-ltsp rpc.mountd[2292]: authenticated mount request from 192.168.0.203:903 for /opt/ltsp/i386 (/opt/ltsp) Application server gives applications. /home is mounted from root server to the application server. Sep 5 18:04:13 debian-app-01 sshd[3133]: Accepted password for ltsp001 from 192.168.0.203 port 54069 ssh2 Sep 5 18:04:13 debian-app-01 sshd[3133]: pam_unix(sshd:session): session opened for user ltsp001 by (uid=0) root@debian-app-01:~# mount | grep /home 192.168.0.105:/home on /home type nfs4 (rw,relatime,vers=4,rsize=8192,wsize=8192,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.0.106,minorversion=0,local_lock=none,addr=192.168.0.105) Remember that root server for LTSP can be AMD64, but do not have to be; but chroot have to be i386. And also application servers have to be i386. If using LTSP-PNP root server got to be i386. So when I open some heavy program like LibreOffice thin client run it in application server, not in root server. root@debian-app-01:~# ps ax | grep libreoffice 3368 ?Sl 0:00 /usr/lib/libreoffice/program/oosplash --writer 3402 ?Sl 0:02 /usr/lib/libreoffice/program/soffice.bin --writer --splash-pipe=6 Best Regards Asmo Koskinen. -- Slashdot TV.

Re: [Ltsp-discuss] Debian LTSP, load balancing
If you are using Gigabit ethernet, you don't need a crossover cable. part of the gigabit spec is to automatically sense whether the devices are plugged into a switch or directly into another machine.

Though I've definitely encountered thin clients which didn't negotiate a link fast enough for auto-sensing to work, and PXE boot would fail, while a genuine crossover worked. And other clients worked fine with the same server. Nothing quite like real-world testing! live well, vagrant pgpC5FmltuDbk.pgp Description: PGP signature -- Slashdot TV. Video for Nerds.

[Ltsp-discuss] troubles with libreoffice as a localapp
Hello, As reported a month ago, I still have a problem with running LibreOffice as a localapp. Here are some details. When I start it from the menu, the progress bar shows for a second and then abruptly disappears. When I start LibreOffice as a remote app on the server it starts just well. If I start a xterm as a localapp and then launch libreoffice from there, I see no debug messages. The progress bar shows for a second and then disappears. There is another web-based java application that don't start at all. The firefox window shows, but it never starts the application. I thought it is a java problem, but currently am able to start java applications as a localapp. Any help would be welcome, because I am kind of stuck with this problem.
