[SOLVED] NFS access denied by server while mounting

Lumify · 03-19-2012, 02:14 AM

I followed the guide to stopping IPtables precisely. Because I have Grub2, I added selinux=0 to the GRUB_CMDLINE_LINUX_DEFAULT line of /etc/defaults/grub and ran #update-grub.

I checked this:

Code:

# netstat -ntlp | grep 111
tcp        0      0 0.0.0.0:111             0.0.0.0:*               LISTEN      686/portmap

Yet still-

Code:

# mount -t nfs -o hard,intr 192.168.0.69:/media/nfs/ /home/laptop/nfs/
mount.nfs: access denied by server while mounting 192.168.0.69:/media/nfs/

I tried without the two options hard and intr, but that doesn't make a difference.

can you change your nfs server format for testing

Code:

#vi /etc/exports
/mount/point  *(ro, no_root_squash)

Code:

#exportfs -a

now try to mount

Code:

#mount -t nfs    serverip:/mount/point  /mnt

After following the instructions on deep27ak's post, it is somehow working (that mount command is a little off though, should be this: #mount -t nfs serverip:/mount/point /mnt).

To find the problem, I've backtracked through these changes. I've re-enabled SELinux and IPTables. Still working. Then I added the two mount (client-side) options, hard and intr. Still working. Then I changed the /etc/exports IP address back to my laptop's specific IP address instead of the wildcard IP, 192.168.0.13. It's still working!?

I essentially reverted everything back to how it was after post #8 of this thread, and it suddenly now works. That's strange. Thank you for your help in troubleshooting this.

P.S. I'm now using 192.168.0.* in /etc/exports, and it works!

I saw lots guys met with nfs login problem.
Well I found what the .... is the problem with that.
You have to give each ip access in /etc/exports file.
Because it is not manage well same ips 192.168.1.0/192.168.1.254 or * same

Just one ip each line and will work it.

I hope it will be helpful to others!
