how to export /home to an unfriendly environment

["Thomas Gebhardt" <gebhardt@HRZ.Uni-Marburg.DE>]

Hi,

when exporting /home writable to public pc rooms by nfs
(nfs means "not for security") one has to rely on the
strength of BIOS passwords to preserve data security. I'd
not like to do that. And even if the BIOS password is
save, one may unplugg the linux box and fake the ip
address (and even the ethernet hardware address) with
a laptop to get access to the data on /home.

As I understand, there is no secure rpc implementation for
linux. So is there a secure way to export /home to an
unfriendly environment?

Kind regards, Thomas
