I find the usual cause of this is either: |
| 21 |
|
| 22 |
- trying to run programs as root, in which case the nfs server will |
| 23 |
squash the gentoo2 request from root to user nobody (uid 65533 or |
| 24 |
such). Solution is no_root_squash option in /etc/exports, usual |
| 25 |
warnings about running as untrusted root apply |
| 26 |
- mismatched uids between the two machines. You may well have a user joe |
| 27 |
on both machines but that doesn't mean they have the same uid. You'll |
| 28 |
need to have some kind of centralised user management system in place |
| 29 |
for this (such as NIS), or dream up some scheme using groups, or |
| 30 |
manually sync the /etc/passwd files on both machines |
