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
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 4-29 and OSS Sockets
Applications on page 4-31 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
/etc/hosts.equiv is bypassed when a remote user attempts to use an rsh
command as the super ID.
These files are sometimes the target of UNIX system intruders. Take standard
precautions for their use on a UNIX system when setting them up for the OSS
environment.
See the hosts.equiv(4) and .rhosts(4) reference pages either online or in the
Open System Services Shell and Utilities Reference Manual for more information
about the content and use of these files.
