Where did you get the no_subtree_check options from? If you'd read it in the man page you'd have seen that you also need no_root_squash. Without this option, the root user on the client is mapped to a non-root user on the server. -- Neil Bothwick WinErr 079: Mouse not found - A mouse driver has not been installed.

[gentoo-user] NFS mounts and uid/gid/user names
Hi, to not to stress the SD-card of my single board computer too much I mounted a directory of my PC via NFS at my single board computer, so that compilations and other task which need to be done while installing will access the hd and not the SD-card. (The singleboard computer is a Cortex A8/OMAP based one: 32 bit. The PC is 64 bit AMD based.) So far so nice...everything works fine: I can see the directory on both ends. In /etc/exports on the PC I entered this: /tmp/NFS 192.168.178.25(async,rw,no_subtree_check) When setting chmod 700 /tmp/NFS, chown root:root /tmp/NFS on the server side (PC) I cannot write to the directory as root on the client side (single board computer). On both sides root is 0:0. When setting chmod 777 /tmp/NFS on the server side, I am able to write at the client side to the that directory, bit listing that files shows me that they become owned by nobody:nobody which is nobody:x:65534:65534:nobody:/nonexistent:/bin/sh on the server side. How can I acchieve, that files written on one side remain the same uid/gid assignment on the other side? Thank you very much in advance for any help! Have a nice weekend! Best regards, mcc
