The /sbin/set_parms program is run automatically when you first boot the system after installation. If you do not install HP-UX onto the system yourself, or you do not provide networking information during the installation, you can add this information later by running /sbin/set_parms initial. See set_parms(1M) for details.

You can reset networking parameters at any time by running /sbin/set_parms again and rebooting the system. Any modifications should be made as soon as possible after the initial installation.

To enter the appropriate set_parms dialog screen to manually add or modify information after booting, log in as superuser and specify

# set_parms keyword

where keyword is one of the keywords in Table 2-1. You will be prompted for the appropriate data. The list of keyword choices is displayed when you enter set_parms without a keyword:

set_parms Usage: set_parms <argument>    Where <argument> can be: hostname timezone date_time root_passwd ip_address addl_netwrk    or initial (for entire initial boot-time dialog sequence)

Changes you make using set_parms will take effect after you reboot the system. See the HP-UX System Administrator’s Guide: Routine Tasks.

NOTE: If a system is having trouble communicating with other systems, check that /etc/rc.config.d/netconf, /var/adm/inetd.sec, and /etc/hosts files all contain the correct official host name.

Table 2-1 The set_parms Keywords

Keyword

Description

initial

Run the entire initial boot-time dialog sequence, in the order hostname, timezone, date_time, root_passwd, ip_address, addl_network.

hostname

Set your unique system or “node” name. This name must contain only alphabetic characters, numbers, underscores, or dashes, and must start with an alphabetic character.

The maximum name length is eight characters unless long host names is set, when the maximum is 255 characters. See “Setting Long Host Names” for details.

timezone

Set the time zone where your system is located. Changing the time zone does not affect the system clock or file dates, which are always maintained in Universal Time (UT).

date_time

Set the current date and time for the time zone. See “Setting the System Clock” for important details.

root_passwd

Set the root password if the current password is null, usually when the system is first initialized. Otherwise, it does nothing.

ip_address

Set the internet protocol (IP) address. If networking is installed, this is an address with four numeric components, each of which is separated by a period with each number between 0 and 255. For example the IP address of example.com is: 192.0.34.166.

If you do not have networking installed, you will not be prompted for the IP address.

addl_netwrk

Set additional network parameters. These allow you to configure additional network parameters, such as the subnetwork mask, network gateway, network gateway IP address, local domain name, Domain Name System (DNS) server host name, DNS server IP address and Network Information Service domain name.

locale

Configure local language settings. You can select the language from a menu provided by set_parms or enter a new language (not shown in the menu) by selecting Others. set_parms will verify that a user-specified language is installed. If not, you must install the language before you can use it with set_parms.
