Hi, I'm trying to build a ltsp-server as versatile as possible (old kernel or not, fat or not...) because clients can be very different... We have actually about 20 servers on Wheezy with NFS chroots with no fat.
At the moment, i install everything in a Jessie virtualbox... with the script attached (thks Richard K and Vagrant C) And i have many questions - NBD seems to be really stable. The only advantage of NFS seems to be able to modify chroot in real time... What do you think ? - I can't login in gnome flashback when the client is not fat... Apparently because there is no 3D acceleration... What can I do ? - In my virtualbox, i can't try ltsp-pnp ... ltsp-update-image --cleanup / remain stuck. Is it possible to have an ltsp-pnp in a virtual machine (will surely be a kvm) ? - Can ltsp-pnp have many kernels ? 586, 686-pae and amd64 ? Thanks for your advices, Nico The script i use... #!/bin/bash #1 install packages (if ltsp-pnp install ltsp-client on the server) apt-get install -y lightdm ltsp-server task-mate-desktop task-french-desktop task-lxde-desktop gnome-session gnome-session-flashback gnome-session-fallback ldm-server ltspfs dnsmasq ltsp-docs aptitude iceweasel-l10n-fr inetutils-ping libreoffice-l10n-fr hyphen-fr mythes-fr chromium-l10n chromium pepperflashplugin-nonfree iceweasel-l10n-fr nano inetutils-ping htop gimp ssh nfs-client gnome-flashback vlc #2 add loop to /etc/modules and reboot the server (reported athttps://bugs.debian.org/756990)* #???????? #3 edit /etc/ltsp/ltsp-build-client.conf to have ARCH="i386" and DIST="jessie" cat > /etc/ltsp/ltsp-build-client.conf << EOFbuild BASE="/opt/ltsp" ARCH="i386" DIST="jessie" FAT_CLIENT_DESKTOP="task-french-desktop" LATE_PACKAGES=" iceweasel-l10n-fr nano inetutils-ping libreoffice-l10n-fr hyphen-fr mythes-fr chromium-l10n chromium pepperflashplugin-nonfree iceweasel-l10n-fr nano inetutils-ping htop gimp ssh nfs-client gnome-flashback gnome-session gnome-session-flashback gnome-session-fallback task-mate-desktop gnome-shell-extensions task-lxde-dekstop vlc " MOUNT_PACKAGE_DIR="/var/cache/apt/archives/" LOCALE="fr_FR.UTF-8" EOFbuild #4 aptitude update && aptitude -y full-upgrade && aptitude clean aptitude update && aptitude -y full-upgrade #5 ltsp-build-client (without parameters) ltsp-build-client --copy-sourceslist --purge-chroot #6 ajout de noyaux ltsp-chroot -a i386 apt-get install -y linux-image-686-pae linux-image-amd64 linux-image-586 #7 Config dnsmasq ltsp-config dnsmasq --overwrite cat > /etc/dnsmasq.d/ltsp-server-dnsmasq.conf << EOFdnsmasq #log-dhcp dhcp-range=192.168.0.0,proxy dhcp-option=17,/opt/ltsp/i386 dhcp-vendorclass=etherboot,Etherboot dhcp-vendorclass=pxe,PXEClient dhcp-vendorclass=ltsp,"Linux ipconfig" dhcp-boot=net:pxe,/ltsp/i386/pxelinux.0 dhcp-boot=net:etherboot,/ltsp/i386/nbi.img dhcp-boot=net:ltsp,/ltsp/i386/lts.conf dhcp-option=vendor:pxe,6,2b dhcp-no-override #pxe-prompt="Press F8 for boot menu", 3 # The known types are x86PC, PC98, IA64_EFI, Alpha, Arc_x86, # Intel_Lean_Client, IA32_EFI, BC_EFI, Xscale_EFI and X86-64_EFI pxe-service=X86PC, "Boot from network", /ltsp/i386/pxelinux # A boot service type of 0 is special, and will abort the # net boot procedure and continue booting from local media. #pxe-service=X86PC, "Boot from local hard disk", 0 enable-tftp tftp-root=/var/lib/tftpboot/ # Disable the DNS server functionality of dnsmasq by setting port=0 port=0 # Don't listen on lo, to prevent conflicts with Ubuntu's local resolver hack (LP: #959037). #except-interface=lo #bind-interfaces EOFdnsmasq service dnsmasq restart #8 Config NFS cat > /etc/exports << EOFnfs # /etc/exports: the access control list for filesystems which may be exported # to NFS clients.
