NFS Share To OS X

NFS Share To OS X

[MJ Jenkins]

I have a user who is on a Mac, and has some data on our RedHat 
Enterprise Linux(RHEL) server that needs to be shared to another RHEL 
box and to her Mac.  All seems to be fine on the RHEL box, and somewhat 
on the Mac.

The problem comes in when the user on the Mac writes files to the NFS 
share.  On the RHEL side the files are owned by user root and group 
nfsnobody.  Has anyone else run into this issue?  I'm not sure if the 
issue is how I am exporting the share to the Mac, or how I have the 
share mounted on the Mac.

Any assistance is greatly appreciated.

Without the content of your /etc/exports, it's impossible to know
what's happening. Mac behave like regular NFS clients. Maybe you have
"all_squash,anonuid=0,anongid=5" in your export parameter, maybe it's
something else entirely.

       I really want to say you need to export the fileshare with the
"insecure" option to make the Mac happy. Unfortunately I cannot check
that right now.

This is the /etc/exports file.  129.169 is the Mac I'm exporting to.  
129.183 is the other RHEL machine.

##### Mount point for Britney Schmidt's Mac Pro #####
/nfs/bsmac 
192.168.129.169(rw,all_squash,no_subtree_check,insecure,anonuid=0) 
192.168.129.183(rw,no_root_squash,no_subtree_chck)


This is /etc/fstab from the Mac.
#storage:/nfs/bsmac       /data1          nfs 
resvport,nolocks,locallocks,intr,soft,wsize=32768,rsize=3276
storage:/nfs/bsmac        /data1          nfs 
vers=3,noowners,nolocks,nolockd,nolock,nonlm,automounted,nosuid,hard,bg,noresvport,intr,rw,tcp,nfc

That 1st line in /etc/fstab is another way I was mounting the share 
trying to solve this one.

Thanks for any assistance that can be provided.

Well you're squashing every user (all_squash) to the anonymous uid 0
(which is root). So you obtain the expected behaviour. Why did you put
these options in the first place?

The only special option you need is "insecure" for BSD (including Mac OS
X) clients.
