SubjectRE: Best way to setup 128MB box that can only cache 64MB
I should have also mentioned that I use this box for playing DVD's (with a

Of course linux does not need 128MB for a firewall.


P.S. The memory zones stuff sounds very interesting and I am looking forward
to any input from the MM gods ;)
