Configuration Files for the Network Services Servers
and Tools
These OSS files contain the same kind of information as is used by Guardian sockets
programs in the Guardian environment. Guardian sockets services are configured
using the following files:
$SYSTEM.ZTCPIP.HOSTS
$SYSTEM.ZTCPIP.IPNODES (for NonStop TCP/IPv6 only)
$SYSTEM.ZTCPIP.NETWORKS
$SYSTEM.ZTCPIP.PROTOCOL
$SYSTEM.ZTCPIP.RESCONF
$SYSTEM.ZTCPIP.SERVICES
There are two versions of the resolver that you can use on a node. Each version has
its own rules for the content of its resolver configuration file:
•
The BIND 4 version is described in the resolv.conf(4) reference page online
and in the Open System Services Shell and Utilities Reference Manual
•
The BIND 9 version is described in the resolv.conf(5) reference page online
and in the Open System Services Shell and Utilities Reference Manual
The Guardian resolver configuration file can be changed from
$SYSTEM.ZTCPIP.RESCONF by using the DEFINE =TCPIP^RESOLVER^NAME. The
equivalent ability for the OSS environment is provided by using the OSS shell export
command or the putenv() function to set the TCPIP_RESOLVER_NAME environment
variable to a value other than /etc/resolv.conf.
HP provides a default version of each of these files. See the TCP/IP Configuration and
Management Manual or the TCP/IPv6 Configuration and Management Manual for
more information about these files; see inetd on page 4-31 and OSS Sockets
Applications on page 4-34 for a description of how to provide these files in the OSS
environment.
rshd
The rshd process does not use a configuration file. However, the behavior of the rsh
commands that it services can be affected by the content of files on targeted systems:
•
For a specific targeted UNIX system, see the rsh or rshd documentation of that
system for more information.
•
For users of an rsh command on a remote UNIX system who want to gain access
to the OSS environment, you need to provide and properly secure the following
configuration files in the OSS file system:
°
/etc/hosts.equiv
°
.rhosts
The hosts.equiv file in the /etc directory of the OSS file system describes which
hosts and which users of each host are allowed to start remote shells on an OSS
system. The .rhosts file resides in the home directory within the OSS file system for
each authorized remote user of the OSS environment. The most important copy of
.rhosts is the one that resides in the home directory of the super ID because
