You can do this, but dhcpd.conf is not the place for it. There are three phases of interaction between the LTSP client terminal and the LTSP server. It is useful to treat them separately in discussing this kind of situation. They are: - terminal boot: DHCP and TFTP - terminal run-time: NFS - desktop run-time: X Windows Your question deals with two aspects: load balancing and redundancy/availability. The first two phases, terminal boot and terminal run-time, *don't* need load balancing; they only need redundancy. The third phase, desktop run-time, is the only one that needs load balancing. You'll find that the DHCP booting and even NFS access of the terminal code are not significant load. It's the desktop apps that consume your resources. It is important to know that (warning: LTSP blasphemy!) there is nothing new or revolutionary about the technology in LTSP. What is revolutionary is the incredible packaging and ease of installation and use. Because of this, questions like this are often answered in places that address the particular technology component, and may say nothing whatsoever about LTSP. The load balancing would come at the X Window level with XDMCP; that's what you'd research. Configure the terminals to support DNS name resolution, and use a round-robin DNS name for the LTSP desktop server (XDMCP query target) in the lts.conf file. And definitely share configs by using NIS, and NFS for home directories. > Something my Boss calls 'Round-Robin', but I've never > really understood what that means. It just means configuring a DNS name with multiple IP addresses. Create a generic name to represent a group of machines, and put in the IP addresses of each machine. A client using that name will connect to any one in the group, essentially at random. If it can't connect, it will try another address in the group. This gives a simplistic load balancing and failover redundancy. - Alan ------------------------------------------------------- The SF.Net email is sponsored by EclipseCon 2004 Premiere Conference on Open Tools Development and Integration See the breadth of Eclipse activity.
