LTSP server

Подбор железа

У меня сервер для толстых клиентов(FAT client) построен на ASUS P5KPL-VM, Intel Core2 Duo E4500, 4Gb RAM (2x 2Gb DDR2 Synchronous 800 MHz), md raid 1 250Gb (2x WDC WD2500YS-18S), тоесть на том что не жалко.

Установка

Устанавливаем

sudo apt-get install ltsp-server-standalone

External DHCP server

if you have external dhcp server you maust add several lines to your dhspd.conf

shared-network eth0 {  # your network interface
  subnet 10.11.25.0 netmask 255.255.255.0 {   # your subnet
  #
  #  other setings
  #
  # LTSP TFTP
       next-server 10.11.25.111;       # ltsp-server ip
       option root-path "/opt/ltsp/amd64";
               if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {
       filename "/ltsp/amd64/pxelinux.0";
       } else {
               filename "/ltsp/amd64/nbi.img";
       }
  #
  #  other setings
  #
}

if you buil i386 client change amd64 on i386 path
