Simpler method for fat/thin client setups

I have a problem with DNS , the client boots up and /etc/resolv.conf on the client gets written as dnserver , even through the original file on the server points to the gateway ip. I tried setting it in lts.conf DNS_SERVER=
but that doesn't seem to help

second problem is I don't see the network printers setup on the server on the thin clients ??

Hi David,

as I write on the ltsp-pnp wiki page, PAE kernels support up to 64 Gb 
RAM. And since fat clients don't consume almost any server memory 
anyway, that memory would only be useful for the thin clients in a 
mixed-mode environment.

Sure, 3 Gb server RAM would be enough for 30 fat clients. Do some 
benchmarks about disk speed and network bandwidth though, you might e.g. 
see that a second PCI-e NIC on the server (with bonding) proves useful.
