LTSP notes

Category:Server administration We spent a fair amount of time trying to set up an LTSP box recently for a small office. This was a new AMD-64 dual processor box. After messing around with Edubuntu 6.10 for AMD-64, we've decided to try the i386 version instead, mainly to get Flash working with sound on the remote clients.

Done:

  • Install Edubuntu-amd64
  • ltsp-build-client for i386
  • Install firefox32 and upgrade
  • Install flashplayer9 (no esd support)
  • Name specific clients in attempt to get local device support working.
  • Install NX Server-Free version (allows 2 users and 2 connections--go to small business server to get 10, or FreeNX)

Notes:
  • LTSP supports primarily ESD for sound. Flashplayer 9 does not support ESD, only ALSA.
  • w32codecs switches Totem/other items to 32bit engine. 32bit sound appears to work on console, but not on clients.
  • Clients register devices as they are plugged in, but do not appear to have them mounted. This is supposed to work, according to the Edubuntu release announcement.
