running by themselves, or under the Enterprise Toolkit—NonStop Edition. rexecd is
started by the inetd process, which must be running for remote SQL/MX
compilations.
For information about the behavior of the rexecd process, see the rexecd(8)
reference page either online or in the Open System Services Shell and Utilities
Reference Manual.
portmap and RPCINFO
The portmap process is a Guardian server process or process pair that converts host
port numbers to Remote Procedure Call (RPC) program numbers. portmap is started
from a TACL prompt, runs as a process named $ZPMn, and is required by products
such as the OSS Network File System (NFS) that use the RPC interface.
The Guardian portmap process corresponds to /etc/portmap on UNIX systems.
For more information about the portmap process, see the portmap(8) reference
page either online or in the Open System Services Shell and Utilities Reference
Manual.
The RPCINFO process is started from a TACL prompt and reports the status of certain
servers, including portmap. RPCINFO is a Guardian process that reports RPC
program numbers and can be used to modify the status of RPC servers available from
your node. RPCINFO provides a means to monitor and change portmap behavior;
RPCINFO is required by the same products that require portmap.
For more information about the RPCINFO process, see the rpcinfo(8) reference
page either online or in the Open System Services Shell and Utilities Reference
Manual.
BIND 9 Domain Name Server and Tools
The Internet domain name server (DNS) runs in the OSS environment as the named
process. It is started from an OSS shell.
The named process provides services comparable to the older Guardian-based T6021
DNS product but implements part of the Berkeley Internet Name Domain (BIND) 9
distribution from the Internet Software Consortium (ISC). Two versions of named are
available:
•
Product T0685, a version based upon BIND 9.2.3, without security features
•
Product T0708, a secure version based upon BIND 9.3
Both versions can be run on an HP NonStop node at the same time if they have been
started on different IP addresses and configured to maintain their own sets of data
files.
The secure version of named can be used with the DNS security extensions. The DNS
security extensions (DNSSEC) are a collection of resource records and protocol
modifications that add data origin authentication and data integrity to the DNS. Domain
name servers that employ DNSSEC add digital signatures to their zone files. By
