NFS does not work with OS X Mavericks

[Mark Halegua]

I’m a novice with macs. Been running a system with CentOS as a server for years, usually Linux (Ubuntu) as workstations. Users sometimes use Windows XP (in a VM – virtualbox connecting via SAMBA).

We just attached a MacMini with Mavericks and have had some problems due I think mostly to permissions issues. The user finds she is locked out of documents she had created previously in Linux, and others are locked out of new docs created now under the mac.

We have the same uer name, now with the same UID. The GID on the mac is wrong, but I want to make sure I don’t bork her system before changing things.

I can, from the terminal, login in as a root or admin user. Can anyone tell me what I can do for her without creating a mess?

Thanks.

There are lots of possibilities on a problem like this:

AFP can be set to “ignore ownership” in which case all the files will be owned by uid 99 (unknown to the server) and set to the UID of the person connected over AFP. (Samba users will see “99”)

Apple supports ACLs as does Linux. Check what ACLs are assigned to the files. (ls -le?)

The immutable bit may be set. Cameras often set this on media and it gets brought over when files are dragged in rather than imported with the camera’s software.
