Of course, DHCP assignment doesn't have to determine the client's eventual XDMCP host. It's quite possible to use broadcasts for the clients, so they get an XDMCP session from the first server that responds (aside: is there any way to make servers delay their response based on their load level, making it more likely to connect to a less loaded server?). You can also set things up so that a chooser is displayed and the user can pick which of the responding XDMCP servers to connect to. While I don't have a use for it personally (I'm currently begging the boss for the cash for even an underpowered cold spare server), I wonder if there might be a need to start documenting this side of things. No, I'm afraid I'm not volunteering - my documentation writing abilities are stretched enough trying to write the odd (poor) bit for the Cyrus IMAPd people. There's clearly significant (growing?) interest in issues with scaling LTSP setups and improving availability. I know there was a fairly big discussion about it a while ago, but IIRC it was directed toward a fairly specific purpose rather than general scaling/availability improvements. Is there a wiki or something where ideas and links to software could be collected? -- Craig Ringer ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _____________________________________________________________________ Ltsp-discuss mailing list.
