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
