NFS Issues

So the other day I was with a friend who owns a Mac (Gasp!) and we wanted to share a file over an ethernet cable and weren't able to; partly because we didnt kow much about what we were doing.

Anyway that made me realize I dont know how to use NFS.  So today i went to the arch wiki and followed the steps there and trying to start a local NFS server and connect to it from the same machine. It doesnt appear to be working and displays:

mount.nfs: access denied by server while mounting 127.0.0.1:/home/bashir/Other/Scratch

I have no idea why this is happening. Any ideas? I should have access since it is the same machine.

here is the only uncommented line in my /etc/exports

/home/bashir/Other/Scratch 127.0.0.1(rw,sync) # Read-write access to a client at IP address

Only uncommented lines in my /etc/host.allow

nfsd: 127.0.0.1/255.255.255.255
rpcbind: 127.0.0.1/255.255.255.255
mountd: 127.0.0.1/255.255.255.255

I dont have the services autostart but i run these to start them

sudo /etc/rc.d/rpcbind start
sudo /etc/rc.d/nfs-common start
sudo /etc/rc.d/nfs-server start

I then try to connect as a client with

sudo mount 127.0.0.1:/home/bashir/Other/Scratch /mnt/Scratch

Both the folders /home/bashir/Other/Scratch and /mnt/Scratch exist.

If there is any other information I need to provide please let me know.  Thanks a ton for the help.

EDIT: I never installed any firewalls or anything.

Re: NFS Issues

IIRC this is an error saying that your permissions don't match. Try temporarily setting permissions for the host-folder to 777 and see what happens...

On second thought: you didn't mention the contents of your /etc/exports? Did you set it up conform the wiki?

Re: NFS Issues

i mentioned the contents of /etc/exports.  Only uncommented line in there is:

/home/bashir/Other/Scratch 127.0.0.1(rw,sync) # Read-write access to a client at IP address

I think that should be correct.

I tried setting it to 777 and it didnt change anything.

I have also been playing around with samba and that works fine.  Even works with the built in gnome tools: can make a samba share with System >> Shared Folders application and mount it with nautilus or from the command line.

sudo mount -t cifs -o username=bashir,password=*** //127.0.0.1/Scratch /mnt/Scratch

Because it works with samba i dont think the paths are an issue; but then again i dont see any reason why it isnt working.

Re: NFS Issues

I have it working with nfs v4. In v4, you need to define the NFS root - maybe try doing that?

Re: NFS Issues

are you sure that 127.0.0.1 is the correct address ? Running "ifconfig" will give you the information you need.

Re: NFS Issues

Hi,
Have you specified a domain in /etc/idmap.conf as per the wiki instructions?

https://wiki.archlinux.org/index.php/NFSv4#ID_mapping

This file needs to be editied on both the SERVER and CLIENT.  The Domain entry should match on both. 

Since you are doing a test on the loopback interface (127.0.0.1), you should only have to modify this once.  However, your other, physical, client PCs will need to have this edited.  I am not 100% positive, but this should translate to any *NIX system where NFSv4 is installed.
