DOMAIN(1M) Domain/OS SysV DOMAIN(1M)
NAME
domain - Domain/OS-specific system maintenance commands and extensions
DESCRIPTION
While providing all of the significant capacity of System V Release 3,
Domain/OS SysV actually represents only a subset of the greater capacity
of Domain/OS. Furthermore, Domain/OS SysV omits some features of System
V that are irrelevant to Apollo(R) workstations. The following
paragraphs describe aspects that are visible to the Domain/OS SysV system
administrator and summarize features of System V not implemented under
Domain/OS SysV.
Domain/OS Additions to the SysV Environment
Pages that document Domain/OS-specific commands are identified with the
heading, "Domain/OS SysV"; pages documenting standard System V UNIX
commands are identified with the heading "SysV".
The /etc Directory
This section describes the Domain/OS-specific commands in the /etc
directory. All systems, even if they only have the Aegis environment,
have an /etc directory. This directory contains:
o Standard System V Release 3 commands and programs used for system
administration and maintenance
o 4.3BSD UNIX commands and programs adapted to perform in a SysV
environment.
o Apollo-specific administrative commands and facilities that were
located in the Aegis /com or /sys directories.
The exact contents of the /etc directory depends on the installed
environments.
The /etc directory contains the following Domain/OS-specific commands:
cpboot Copy the system boot file sysboot
ctnode Catalog a node in the network
ctob Catalog an object
drm_admin NCS data replication manager administrative tool
dtcb Dump contents of tcp control blocks

Domain/OS SysV Extensions
This section describes Domain/OS extensions to standard System V UNIX
commands.
Security Features
Domain/OS /bin/login includes new security features for dial-up lines,
/etc/d_users and /etc/d_passwd. /etc/d_users is simply a file containing
a list of users authorized to log in on a node. /etc/d_passwd is a file
containing lines which specify a user's log-in shell, and the dial-in
password for the specified shell as returned by crypt(3) (see login(1)).
Under Domain/OS SysV, /etc/passwd is a read-only object of the type
"passwd," and /etc/group is a read-only object of the type "group," both
maintained by the registry server (see rgyd(1M) and Managing SysV System
Software). The administrator can make the information in the registry
read-only.
Soft links in Domain/OS have no protections associated with them.
Symbolic links are implemented as soft links.
Extensions to Utilities
routed(1M) The routed command includes a number of Domain/OS
extensions:
-n Directs routed not to install changes into the
local routing table. However, the routed
process continues to receive broadcasts from
other routed processes. The -n option is used
for debugging purposes.
-f Directs routed at startup to "flush" (purge)
all routes from the local routing table,
except routes added manually with /etc/route.
-h Exits, if not supplier, when routing table is
stable. Use this switch on hosts only, not on
gateways.
sendmail(1M) Sends a message to one or more recipients, routing
the message over whatever networks are necessary.
tftpd(1M), tftp(1C) The Domain/OS SysV versions of tftpd and tftpd(1M)
are adaptations of the MIT Project Athena
implementations of the tftp protocol. Domain/OS
SysV tftp will interface with any RFC783 compliant
implementation.
trpt(1M) Interrogates the buffer of TCP trace records
created when a socket is marked for "debugging"
(see setsockopt(2)), and prints a readable
description of these records.
The trpt command includes a number of Domain/OS extensions:
-c Clears trace buffer.
-d <PCB addr> Toggles debug on a connection.
-e Exits on a bad trace record.
-l Prints lapsed times, in addition to
the normal output.
- Warns on bad trace records.
TCP/IP Support
At SR10, TCP/IP software is a part of the base operating system. At SR10,
TCP/IP has a single implementation that follows the 4.3BSD UNIX model and
works in all three environments: BSD, Aegis, and SysV.
UUCP Support
At SR10, Domain/OS supports only the System V HoneyDanBer version of UUCP
in both the BSD and SysV environments.
