Description Ray Finch 2001-06-13 15:21:41 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.61 [en] (X11; U; Linux 2.2.12-20 i686)

Description of problem:
the nfs partition appears to mount according to the 'df' command, but the
'ls' command show an empty directory. The following shows up the
/var/log/messages:

Jun 13 07:54:01 sturgeon kernel: call_verify: server requires stronger
authentication.
Jun 13 07:54:01 sturgeon kernel: NFS: cannot retrieve file system info.
Jun 13 07:54:01 sturgeon kernel: nfs_read_super: get root inode failed
Jun 13 07:54:01 sturgeon kernel: nfs warning: mount version older than
kernel

and after the ls command

Jun 13 07:55:08 sturgeon kernel: call_verify: server requires stronger
authentication.
Jun 13 07:55:26 sturgeon last message repeated 10 times



How reproducible:
Always

Steps to Reproduce:
1. mount sunbox:/home /home	
2. df /home
3.  ls /home
	

Actual Results:  'ls /home' showed an empty directory

Expected Results:  we should see a list of user directories.

Additional info:

This machine has a single processor and was configured as a workstation
with almost everything installed.

I suspect the server is expecting some flavor of secure RPC for filesystem
access, but not requiring it for mounting the filesystem.  Currently, Linux does
not have support for secure RPC.  Reclassifying under "kernel", which implements
the NFS client functionality.
