Dear list readers - Having an interesting problem that i cannot seem to find a good answer for, so i thought i would throw it out to the list and maybe learn something in the process. I have an unusual issue on an auto-mounted over NFS data directory. The users are complaining that they get permission problems when copying files in their own directories, and when i took a look from one of the workstations that had the data directory mounted, at first things appeared ok, i saw what i would expect to see, example: drwxr-sr-x 2 yangj2 qinlab 98 Jun 2 20:08 PDB_files -rw-r--r-- 1 yangj2 qinlab 4567 Jan 18 2008 prompt.txt drwxr-sr-x 2 yangj2 qinlab 6 Apr 10 2007 .qt -rw-r--r-- 1 yangj2 qinlab 111789 Aug 13 12:21 Restraints.py.pdf drwxr-sr-x 18 yangj2 qinlab 18 Oct 16 11:43 Scripts drwxr-sr-x 7 yangj2 qinlab 7 Aug 4 2006 Setup_Files drwxr-sr-x 8 yangj2 qinlab 34 Aug 21 13:13 Test drwx--S--- 3 yangj2 qinlab 3 Apr 3 2007 .thumbnails drwxr-sr-x 2 yangj2 qinlab 2 Oct 31 16:39 Transfer -rw-r--r-- 1 yangj2 qinlab 2 May 10 2005 update_20060201 -rw------- 1 yangj2 qinlab 5703 Apr 10 2007 .viminfo -rw------- 1 yangj2 qinlab 160 Apr 10 2007 .Xauthority note: that is from a fedora core 2 machine. But when i took a look from another one of their machines mounting the exact same share, i see the following: drwxr-sr-x+ 2 yangj2 qinlab 98 2008-06-02 20:08 PDB_files -rw-r--r--+ 1 yangj2 qinlab 4567 2008-01-18 15:59 prompt.txt drwxr-sr-x+ 2 yangj2 qinlab 6 2007-04-10 13:50 .qt -rw-r--r--+ 1 yangj2 qinlab 111789 2008-08-13 12:21 Restraints.py.pdf drwxr-sr-x+ 18 yangj2 qinlab 18 2008-10-16 11:43 Scripts drwxr-sr-x+ 7 yangj2 qinlab 7 2006-08-04 15:49 Setup_Files drwxr-sr-x+ 8 yangj2 qinlab 34 2008-08-21 13:13 Test drwx--S---+ 3 yangj2 qinlab 3 2007-04-03 16:56 .thumbnails drwxr-sr-x+ 2 yangj2 qinlab 2 2008-10-31 16:39 Transfer -rw-r--r--+ 1 yangj2 qinlab 2 2005-05-10 15:20 update_20060201 -rw-------+ 1 yangj2 qinlab 5703 2007-04-10 14:38 .viminfo -rw-------+ 1 yangj2 qinlab 160 2007-04-10 14:56 .Xauthority note: that is from a fedora 7 machine. The mount is auto-mounted over nfs from a Solaris 10 x86 running ZFS. What is puzzling me is the '+' character in the permissions, which i am honestly unfamiliar with. After a little digging i believe this is indicative of some extended ACL that is applied somewhere but i cant seem to determine where. Its not the older FC boxes, i dont THINK its the solaris box, and i am hedging a bet its the F7 boxes, but not sure at this point exactly what it is. Is it NFSv4, or something else? And how can i remove that set bit from the files and directories. Not sure if thats really the problem, but on systems that i DONT see that '+' we dont have the problem. Any direction or ideas would be greatly appreciated. Thanks in advance Michael Weiner
