Controlling Network Services
Most of the Internet and RPC services are managed automatically by the
inetd(1M)
Internet Services daemon. These services are specified as entries
in the
/etc/inet/inetd.conf
file (or
/etc/inetd.conf
, which is symbolical-
ly linked to
/etc/inet/inetd.conf
).
The
inetd
daemon is started automatically at system boot, or can be started
manually by executing the
/etc/init.d/inetd start
command. The servic-
es that the
inetd
controls are started as needed. Likewise, all Internet and
RPC services controlled by the
inetd
daemon are stopped automatically
when the system is shut down or can be stopped manually by executing the
/etc/init.d/inetd stop
command.
Individual Internet and RPC services can be stopped by using the
kill
or
pkill
command to send a signal to the process that provides the service.
However, the
inetd
daemon should be reconfigured so that it will not try to
restart the service.
To reconfigure the
inetd
daemon, edit the
/etc/inet/inetd.conf
file and
delete the entry for the service. Then use the
kill
command to send the
hang up signal (
SIGHUP
) to the
inetd
daemon. This causes the
inetd
daemon
to reread the
/etc/inet/inetd.conf
file. Also, the
/etc/init.d/inetd
script
(as previously described) can be used to stop and restart the
inetd
daemon or
the system can be rebooted.
The Solaris Network Environment
The Solaris 9 network environment supports several types of system config-
urations, including standalone, diskless, and AutoClient. These configura-
tions provide different capabilities and impact deployment and support costs.
Standalone Configuration
A
standalone
system has local disk space that is used to store all operating sys-
tem files, applications, and user data. This includes the root (
/
),
/usr
,
/export/home
, and
/var
file systems. Likewise, it provides a local swap for
the system's virtual memory. A standalone system can function autonomous-
ly and can be either networked or non-networked. A networked standalone
system can be used as a server, such as a file server, to provide remote access
to shared or common data.
