Can someone kindly explain what is going on here:
Machine A: FreeBSD - was running 8, just upgraded to 9.1-PRE
(I don't recall seeing the behavior described below
in V8, but then, I don't think I ever tried it).
Machine B: Linux Mint Desktop
- Machine A acts as an NFS server for Machine B.
- Machine A exports a particular directory like this:
/usr/foo -maproot=myid -network ...
- /usr/foo/bar is owned by root on Machine A and has files therein
owned as root:root with permissions of 600.
- If I access /usr/foo/bar/file1 from Machine B, I cannot read it
but - and this is the part I don't get - I CAN *rename* it.
What's going on? Since /foo/bar/ is owned by root and everything
in it is 600 root:root, I would not expect a remote access to allow
things like renaming. Clearly I am missing something here, but I
don't get it.
What are the permissions on the directory /usr/foo/bar?
775
Let me correct something. The files in that directory are
owned by root:wheel (not root:root - I got my *nixes
confused), but they definitely have 600 perms.
On Machine A, user 'myid' is IN the wheel group but I still
don't see how he's getting permission to rename the file.\
Renaming a file does not change the file itself. It updates the directory.
Any user in group wheel has the authority to write to the directory (e.g.,
change a file's name). The directory permissions are rwx for group wheel. You
can either try a user on machine B who is not in group wheel or change the
directory permissions to 755 on /usr/foo/bar. Then it would work as you expect.
D'oh ... of course that's it. Thanks.
