So a while ago the plan was to add load balancing support to ltsp since at the school of Engineering at Oakland we have multiple boxes that use to server out thin clients to Sunrays. The Sunrays went away due to their general crappiness, but mostly due to the crappiness of the Sunray server software. Few months before we moved to X terminals for thin clients using LTSP. One snafu is that we lost the ability of having more then one machine for people to log into. So for the past month or more I’ve been working on adding some support for that to ltsp.
Now I finally got some things going. Now this is still rudimentary addition, with little testing but it’s a start. I added support to ldm for connecting to multiple machines basically what happens is ldm has a list of server and as it sits there ldm just checks them constantly (every 5 secs or so). When a user puts a username and password ldm already has the best server picked out. The is a bzr branch available at http://ltsp.mindtouchsoftware.com.
We’re getting 3 more machines to serve out thin client desktops. So this will make a great addition so we can use all of them.
In other news I got a “real” job…

Hi,
If you have time, I would greatly appreciate it if you could write an LTSP load balancing HOW-TO doc. (or if you could point me to an already existing one.)
I’m currently writing a paper on Thin Client Computing for a project to reduce electronic waste (ewaste) in Latin America. I’ve already writen 100 pages and figure that I have about 30 more pages to write. The goal is to teach people how to use their old computers for longer periods, since throwing away old computers creates toxic waste which isn’t properly recycled in Latin America or many other parts of the world. In addition reusing old computers avoids buying a new computer, and 81% of the total energy used by a computer lies in the original manufacturing. I am trying to recommend free or open source software solutions so that people don’t have to violate software licenses. For that reason, I would be very interested in finding a load balancing solution that I can recommend in my paper.

Hi,
I would also really appreciate it if you could put together a how-to doc. I am in South Africa and we would like to be able to re-use oldish desktop computers as thin client cluster ltsp servers. The idea is that instead of schools having to buy a big expensive server, we could use cheaper or second desktop computers in an ltsp cluster for their thin clients. So I would really love to see what you have done.
