NIS Vs. NIS+
NIS and NIS+ are only similar in their purpose and name; otherwise, they have completely different implementations. They differ in the following ways:
- NIS+ is hierarchical.
- NIS+ is based around Secure RPC (servers must authenticate clients and vice-versa).
- NIS+ may be replicated (replicas are read-only).
- NIS+ implements permissions on directories, tables, columns and rows.
- NIS+ also implements permissions on operations, such as being able to use nisping to transfer changed data from a master to a replica.

Famous quotes containing the word nis:
“O yonge fresshe folkes, he or she,
In which that love up-groweth with your age,
Repeyreth hoom fro worldly vanitee,
And of your herte up-casteth the visage
To thilke God that after his image
Yow made, and thynketh al nis but a faire
This world, that passeth sone as floures faire.”
—Geoffrey Chaucer (1340–1400)
