Sure... now, how do you check the dashboard or fuel cap "REMOTELY" ? :) (checking the fuel cap is like checking the labels on the server, or the model of the box ,etc). > Rebooting with an SMP kernel seems like the slow way to find out.

(or get them to open the box and see how many cpus it has ;) ) Beto
