Aside from a few that are set up for testing, no Linux NFS servers support IPv6 yet. exportfs and mountd in mainline nfs-utils don't yet support IPv6. It's supported in rpc.nfsd, but hardcoded off for now until mountd and exportfs catch up. Chuck Lever has a patch stack for mountd and exportfs in his nfs-utils tree that basically works, but it's still preliminary and not ready to be committed yet. More testing of that code would be helpful. -- Jeff Layton <jlayton@xxxxxxxxxx> -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
