OK, I wasn't sure if you'd know Radio Shack as you are in Barcelona, right?
Anyway, I did set to worker up to netboot on my gigabit switched ethernet LAN (no crossover cable) and node 0 seems to be assigning a ton of IPs in a row but my worker node is never found....
I guess I'll try to netboot with a crossover cable next. However, I really would like to get all 50 cores into a pelucanHPC cluster!
Thanx for your help,
