On OS server. root at nas1:~# share -F nfs -o rw,root /files/files
On Ubuntu client. root at www:~# mount 192.168.10.50:/files/files /mnt/test root at www:~# cd /mnt/test/ root at www:/mnt/test# ls root at www:/mnt/test# touch ff touch: cannot touch `ff': Permission denied root at www:/mnt/test# ls -ld drwxr-xr-x+ 2 root root 2 Sep 13 02:25 . root at www:/mnt/test# id uid=0(root) gid=0(root) groups=0(root) Now, here is something strange, using same setup from above. On server. root at nas1:~# cd /files/files/ root at nas1:/files/files# mkdir tmp root at nas1:/files/files# chmod 777 tmp/ On client root at www:/mnt/test# cd tmp/ root at www:/mnt/test/tmp# ls -l total 0 root at www:/mnt/test/tmp# touch ff root at www:/mnt/test/tmp# ls -l total 1 -rw-r--r--+ 1 4294967294 4294967294 0 Sep 13 14:30 ff root at www:/mnt/test/tmp# su - www-data www-data at www:~$ cd /mnt/test/tmp/ www-data at www:/mnt/test/tmp$ touch tt www-data at www:/mnt/test/tmp$ ls -l total 1 -rw-r--r--+ 1 4294967294 4294967294 0 Sep 13 14:30 ff -rw-r--r--+ 1 www-data www-data 0 Sep 13 14:33 tt Looks like files created by root on the client get mapped to some other user. Mat be related to reason why I can't create files as root in the root of the mount. And to answer the other question, this is not production. It's at home right now. Thanks for the help so far.
