How about passing different users to a different desktop server? Balancing them across a number of desktop servers could definitley be useful for also reducing the damage when a server goes down.
My biggest point of failure is the network switches. Once every two months or so, one of them will freeze and blast the network with garbage. It's not so bad if only a subset of workstations go down but even when problems are rare, one big massive outage of workstations can really piss people off. Did he by chance mean that perhaps dhcpd.conf migh somewhere be able to send a client to different LTSP images to lead balance the desktop servers where lts.conf files piont to different desktop servers? BTW: I wonder if it's possible to make X sessions remain when cut-off, so one could just login and continue where he/she left off? This is a big plus with Windows Terminal Services. BTW: rdesktop's 24-bit color support (CVS version) is working pretty well! It did disappear on me once in the last two days since I've been using it in production, but the work was waiting untouched when I logged the user back into Windows. --- Julius Szelagiewicz <[EMAIL PROTECTED]> wrote: > On Fri, 24 Oct 2003, Gad wrote: > > I've read yours Embedded Terminal Server howto and > i'm very interested in > > doing something like > > this.
