Some handy resources for thin clients and virtual machines

I’ve been researching options for thin clients over the past few months and trying to get my Fit PCs to boot over LTSP / etherboot (still no joy so far). I do have them working as thin clients via XDMCP thought. Along the way I have found some handy websites which I thought I would make a note of here:

VM from GDM – This one explains how to set up a custom session type so that it logs you directly into a virtual machine instance from the Gnome Display Manager. So you get a full screened windows or whatever session with no Gnome running in the background.

Thin Client Howto – This one is a slightly out of date but still useful run through on how to get clients booting via etherboot.

disklessworkstations.com – This is a commercial vendor of tin client workstations, some of which support dual screen which is useful for GIS workers and software developers. I havent purchased any of their products & would love to hear from those who have.

Ubuntu LTSP quick install guide – contains a useful hint when setting up a 64bit server with 32 bit clients (sudo ltsp-build-client –arch i386 )

This guide has a few handy nuggets like reminding you that every time you update the server you should rerun

ltsp-update-kernels
ltsp-update-image
ltsp-update-sshkeys

One other thing to note is that I believe LTSP is now bundled with the Ubuntu alternate CD so I’m thinking I might do a complete system re-install when 9.10 comes out.

I really want to get this LTSP stuff working nicely – I think its an enviromentally responsible way to go (my FIT-PC’s only consume around 7 Watts of electricity) and makes a lot of sense in terms of configuring and securing one server and all your clients automatically benifiting from a single admin action.
