To appeal to the windows users you need everything packaged in a simple i...

Hmmm..... These must be really interesting proteins as I am folding 12 of them now!

Results from completed WUs:

09.33 DUAL P3 1.4G(1 client)
07.18 P4 2.2G (400FSB) (farm client)
07.17 P4 2.2G (400FSB) (win2k)
07.29 MP 2200 (1 client)
06.32 P4 2.4G

Nice to see linux folding just as well as win2k.

The standard LTSP kernel uses modules for ALL NIC drivers. None of them are compiled in.

The heatsink here is about 40 pounds ($100AUD) so it does seem pretty expensive there. As for running only one PSU fan, with my system it works ok but only because I have undervolted from 1.5 to 1.1 volts (bios won't let me go any lower). Without undervolting another fan would probably be needed. I...

No bridge neccessary.
I've read where this value goes away following a reboot, so needs to be placed in a startup script. Where should it go?

Type the following as root on the farm server,

echo "1" > /proc/sys/net/ipv4/ip_forward

To test you need to connect a PC to the subnet and ping the dlink router.
