I find the usual cause of this is either: - trying to run programs as root, in which case the nfs server will squash the gentoo2 request from root to user nobody (uid 65533 or such). Solution is no_root_squash option in /etc/exports, usual warnings about running as untrusted root apply - mismatched uids between the two machines. You may well have a user joe on both machines but that doesn't mean they have the same uid. You'll need to have some kind of centralised user management system in place for this (such as NIS), or dream up some scheme using groups, or manually sync the /etc/passwd files on both machines alan -- Optimists say the glass is half full, Pessimists say the glass is half empty, Developers say wtf is the glass twice as big as it needs to be?
