It seems that with current nfs-utils, "proto=udp" (either in /etc/nfsmount.conf or on the command line) restricts the mount to using IPv4, not IPv6. For IPv6 you need "udp6". This isn't made crystal clear by the documentation. I could fix the documentation, but first I wanted to check if this really is appropriate. Is there a good reason for this, or should we make "udp" mean "udp4 or udp6" and require either "udp4" or "udp6" if we want a particular IP version. i.e. instead of treating the "proto=" value as a "netid", should we treat it as a "protoname" and match any "netid" in /etc/netconfig with that "protoname"?? Thanks, NeilBrown
