Chapter 10. Network Administration

10.1 Network Startup at Boot Time

At IPL time, the /etc/inittab will start /etc/rc.tcpip after starting the SRC. If you have installed the IBM AIX SNA Manager/6000 (program number 5765-233), /etc/inittab will start SNA too.

The /etc/rc.tcpip file is a shell script that, when executed, uses SRC commands to initialize selected daemons. It can also be executed at any time from the command line.

Most of the daemons that can be initialized by the rc.tcpip file are specific to TCP/IP. These daemons are:

• inetd (started by default)

• gated

• routed

• named

• timed

• rwhod

Note
Running the gated and routed daemons at the same time on a host may cause unpredictable results.

There are also daemons specific to the base operating system or to other applications that can be started through the rc.tcpip file. These daemons are:

• lpd

• portmap

• sendmail

• syslogd

The syslogd daemon is started by default.
