Description David O'Brien 2011-08-09 06:53:56 UTC
Description of problem:

Server = RHEL 6 CSB
Client = RHEL 5.7 workstation

with 5.7 set up as the server I could mount dirs on CSB ok.
With CSB as the server I had to jump through all sorts of hoops (ask steved) to get it working.

Mostly I received the following sorts of errors:
failed: RPC Error: Authentication error
mount: mount to NFS server 'daobrien' failed: RPC Error: Program not registered

Trying with nfs4 produced:
mount.nfs4: Permission denied

Firewall on both ends disabled.
SELinux in permissive.

Command used on client:
[root@jupiter ~]# mount -vvv daobrien:/home/daobrien/sandbox/OpenShift /home/david/sandbox/

# cat /etc/exports
/home/daobrien/sandbox/OpenShift *(rw,no_root_squash)

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. Export a dir on the server
2. Disable both firewalls while setting up/testing
3. Run mount command as described above
Actual results:
Error messages as shown above. /var/log/messages also shows messages like:
Aug  9 02:25:30 daobrien rpcbind: connect from to getport/addr(nfs): request from unauthorized host

Expected results:

Additional info:
eventually ran this to get it to work:
pkill rpc.mountd && service nfslock restart && service nfs restart


commented out all lines in /etc/hosts.allow
# ALL:         : ALLOW
# sshd:           ALL             : ALLOW
# ALL:            ALL             : DENY

http://fpaste.org/Kwtg/ has rpcinfo -p (for now).

I did try adding nfsd to the allow list but that didn't help.

Comment 2 Steve Dickson 2011-08-12 12:11:28 UTC
It turns out this is not a bug... When I added the following entries
to /etc/hosts.allow

rpcbind:           ALL             : ALLOW
mountd:           ALL             : ALLOW

the mount worked.
