Re: Kernel Compiling

Understood everything. THanks for clarifying.

I will send you the info for my server. I would like to give you an always
up server but it's not the case. The only one I have access is my ISP one
and I cannot put that for you. But I can give you access to a part of my
home server and it's almost always up.
