Re: [Openmosix-devel] [wishlist] untrusted nodes in hpc.map

[Peter W. <psy...@ph...>]

is this trust level supposed to be implemented on the remote nodes or the
local node? in other words, are you trying to stop the local pc from
migrating nodes based on uid/gid, or stop a machine from accepting a
migrated process based on uid/gid? if you're talking about stopping a
certain user/group from migrating a process to another node, that could
probably be done. but if you're talking about letting a process from a
remote node run on a local machine for example, that wouldn't be secure
without some kind of authentication. you could just spoof the uid/gid and
migrate any process to any node.
