NFS msg: Unable to find suitable address

[Dennis Wicks <wix@mgssub.com>]

This is what happens:

	sudo mount //robin/znfs/edrv -o user=,password= /mnt
	Unable to find suitable address.

The server is Jessie 8.7 and NFS-V4 (I think!)

The directory is exported as:
	/znfs/edrv/ *(rw,sync,no_subtree_check,root_squash)

And the mount is:	> /dev/sdf1 on /znfs/edrv type ext3 
(rw,relatime,data=ordered)

I can't find any info that looks like a solution to the problem.

Anybody have a clue? A hint? Seen it before?

As usual, Many TIA!!
Dennis
