1 ONCplus Release Notes This document contains the most recent product information pertaining to the Open Networking Computing (ONC) product, version B.11.31.03, which is supported on the HP-UX 11i v3 operating system. This document addresses the following topics: • • • • • • • • • “Announcement” (page 8) “Overview” (page 8) “What's New in ONCplus B.11.31.03” (page 9) “Fixes in ONCplus” (page 10) “Installation Information ” (page 12) “Features Introduced in ONCplus B.11.31.
Announcement This version of ONCplus (B.11.31.03) is supported on systems running the HP-UX 11iv3 operating system. Availability of ONCplus as an ISU Prior to the HP-UX 11i v3 release, ONC was delivered as a core product called NFS. Core products cannot be released independent of the operating system. Any changes (defect fixes, for example) to core products are only available to customers by installing HP-UX patches. For HP-UX 11i v3, ONCplus is available as an Independent Software Unit (ISU).
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.
server, can traverse the file system “/a/b” on the server without mounting the file system explicitly. • Referrals and Multi-server Namespace The Cross Mount Traversal feature allows an NFSv4 client to traverse the servers shared directories and seamlessly cross the physical file system boundaries on the server. The Referrals feature allows an NFSv4 client to traverse shared directories and seamlessly cross the physical file systems located on different servers.

Installation Information This section specifies the requirements for installing ONCplus B.11.31.03. It includes information on installing ONCplus B.11.31.03 and verifying the ONCplus B.11.31.03 installation. System Requirements The following requirements are necessary for installing ONCplus B.11.31.03 : • • • Hardware Requirement: Itanium / PA-RISC Software Requirement: HP-UX 11i v3 Free Disk Space: 50 MB Installing ONCplus B.11.31.03 To install ONCplus B.11.31.03 on your system: 1. 2. Login as root.
2. To check which version of ONCplus is installed on your system, issue the following command: swlist | grep ONCplus The output should be similar to the following: ONCplus B.11.31.03 ONC+ 2.3 Reverting to a Previous Version of ONCplus You cannot remove the current version of ONCplus with the swremove command. However, you can revert to the previous version of ONCplus. The following section describes how to revert to the previous version of ONCplus.
New CacheFS Features in ONCplus B.11.31.02 CacheFS introduces the following features: • Support for ACLs An access control list (ACL) offers stronger file security by enabling the owner of the file to define file permissions for specific users and groups. HP-UX supports two types of ACLs: HPUX_ACLS and SYSV_ACLS. HPUX_ACLS are non-POSIX compliant. SYSV_ACLS are POSIX compliant. This version of CacheFS supports caching for only SYSV_ACLS.
Features Introduced in ONCplus B.11.31_LR The following features were introduced in ONCplus B.11.31_LR: 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.
firewalls and enables applications that run on heterogeneous operating systems to access shared files. • Secure NFS With Secure NFS security can be implemented at the Remote Procedure Call (RPC) level. This standard authentication system is known as Secure RPC. When NFS uses the facilities provided by Secure RPC, it is known as Secure NFS. RPC authentication enables you to use a variety of authentication systems, such as DH, UNIX, and KERB, and is not dependent on the version of NFS used.
• Backend Support AutoFS supports the storage and distribution of AutoFS maps in the following: — Files — Network Information Service (NIS) — Lightweight Data Access Protocol (LDAP) • Filesystem Support AutoFS supports the automatic mounting and unmounting of the following filesystems: — NFS (All versions including NFSv4) — CacheFS — HFS — VxFS — CIFS — AutoFS • Secure NFS Support If the NFS client supports mounting of secure directories, AutoFS supports Secure NFS filesystems.
— — — noconst Disable consistency checking. demandconst Consistency checking is performed on demand. weakconst Consistency check used to verify cache consistency with the NFS client's copy of the attributes. weakconst is the consistency checking level similar to the default behavior in HP-UX 11iv2. NOTE: • Consistency is not checked at file open time. Switching Mount Options You can switch between mount options without deleting or rebuilding the cache.
• Ipnodes Support Ipnodes is the new map that stores IPv6 information. Ipnodes acts as the new hosts database for IPv6 information. NIS provides support for ipnodes using the /etc/nsswitch.conf file. • Alternate Directory for passwd File Users can now specify a directory other than the default /etc directory where NIS must look for the passwd file. This feature enhances the security of the system, as information regarding this alternate directory is known only to the administrator.
