by the cache directory (also known as the working set size). This command uses the logfile
created by the cachefslog command to display the information. The cachefswssize
command, used with the -a option, displays the information in ASCII format.
New NIS Features in ONCplus B.11.31.02
NIS introduces the following features:
• Support for IPv6 Protocol
The NIS clients and servers are now IPv6 enabled. Therefore, you can set up an NIS master
server, an NIS slave server, or an NIS client that can be identified using an IPv6 address. The
IPv6 information is stored in ipnodes, which are supersets of hosts that act as the new databases
for IPv6 information.
• Support for Resolving Map Nicknames
NIS supports the creation of nicknames for maps. You can create or update the nicknames
associated with the maps. The ypcat and ypmatch commands use the /var/yp/nicknames
file to resolve or modify nicknames.
• Support for NIS ypbind v3 Protocol
The NIS client supports version 3 of the ypbind protocol. Version 1 of the ypbind protocol
is obsolete and any request from an NIS client to ypbind version 1 is rejected.
• Reduced Usage of Reserved Ports
Reserved ports are the ports from 0 to 1024. Only root users can bind to these ports. In
previous releases, NIS commands attempted to bind to reserved ports by default. If there are
numerous client requests, all the reserved ports can be consumed. This version of NIS enables
binding to reserved ports for select commands or daemons when accessing secure maps which
results in reduced usage of reserved ports by NIS. This change does not compromise
performance or security.

New NFS Features in ONCplus B.11.31_LR
• NFS Version 4 Protocol (NFSv4)
NFSv4 is an IETF standard protocol that provides the following features:
◦ COMPOUND Procedure
In NFSv4, related RPC requests are grouped into a single RPC procedure known as the
COMPOUND procedure.
The COMPOUND procedure decreases transport and security overhead because of fewer
over-the-wire trips between the client and the server. This feature is transparent to the user.
◦ Delegation
In NFSv4, the server can delegate certain responsibilities such as, OPEN, CLOSE, LOCK,
LOCKU, READ, and WRITE to the client. Delegation enables a client to locally service
operations without immediate interaction with the server. Delegations can be revoked by
