ONCplus B.11.31.04 Release Notes

ONC consists of the following components:
• Network File System
The Network File System (NFS) is a distributed filesystem that provides transparent access
to files and directories that are shared on remote systems.
• AutoFS
AutoFS is a client-side service that enables automatic mounting and unmounting of
filesystems.
• CacheFS
The Cache Filesystem (CacheFS) is a general purpose filesystem caching mechanism that
improves the performance of client side applications when working with NFS servers.
CacheFS client performance is improved by caching data to a fast local file system instead
of going over the wire. Caching data results in reduced server and network load because
the clients have already cached a copy of the data and send fewer requests to the server.
• Network Information Service
Network Information Service (NIS), previously called “Yellow Pages,” is a distributed
database system that enables the maintenance of commonly used configuration information
on a master server and propagates the information to all the hosts in the network.

New NIS Features in ONCplus B.11.31.04
NIS introduces the following features:
• IPv6 support for RPC commands and daemons
ONCplus B.11.31.04 delivers IPv6 support for rpc.rexd, rpc.rwalld, rpc.rusersd, rusers, and
rwall commands and daemons. Other RPC commands and daemons (rpc.statd and
rpc.rquotad) will support IPv6 in a future release of ONCplus.
NGROUPS Expansion
The NGROUPS expansion enhancement to HP-UX 11i v3 Update 3 changes the maximum number
of groups for a user or process to be a tunable parameter. This allows customers to implement
models for file access and protection that were not possible under the previous limit of 20 groups
per user. Before deploying such models, customers must update the HP-UX kernel and utilities,
and ensure that their local applications are compatible with the expanded group limit. ONCplus
has the following limitations regarding the number of groups per user:
• The records, which can be passwords, groups, hosts, netid, etc., in the NIS database are
limited to 1024 characters. The use of extremely long group names can cause the 1024
