NFS Support

The ReadyNAS NFS “just works.” This is unlike the Western Digital ShareSpace which has weird omissions that cause application-level problems; some are showstoppers. ReadyNAS NFS has:

NFS v3, tcp
Appropriate NFS protocol negotiation at mount.
IPv6 seems to be “enableable” on the RNDU4000 (unclear what that means).
NFS v4 from a Fedora client’ has

Root Access

Configurable to add no_root_squash from the (FrontView GUI)
Configurable to a CIDR network; e.g. 192.168.135.0/24
BUT this seems to have been removed on RAIDiator 5-series as experienced on the ReadyNAS NV+ v2 (RNDU4000-200NAS)

SSH Access

Available, by factory add-on, but untested
Voids warranty, apparently
