Sample Files

This section covers the following sample files:

script Resource File

The following is an example of a customizing script that configures the target's TCP/IP domain name resolution and routing.

Manual customization is still necessary when configuring Domain Name Services for AIX 4.1 NIM clients. The resolv_conf resource should be used when installing clients running the latest version of AIX.

#!/bin/ksh  CUSTOMIZING SCRIPT to set the hostname,
#             establish the nameserver and DNS domain name,
#             and configure the routing table for the
#             target standalone client

# Truncate the host name
# if the host name is set to the fully qualified host name
#
#NOTE: This procedure will NOT result in a truncated host name if
#the bos installation operation is installing a mksysb image
#(ie. -a source=mksysb) unless the bos_inst operation is
#instructed not to configure the target as a NIM client upon
#completion (ie. unless -a no_nim_client=yes is specified)
#
chdev -l inet0 -a hostname =$(/usr/bin/hostname | cut -d. -f1)
# Set Name server and Domain Name

if [[ -f /etc/resolv.conf ]]
then
   /usr/sbin/namerslv -E '/etc/resolv.conf.sv'
fi
/usr/sbin/namerslv -a -i '9.101.1.70'
/usr/sbin/namerslv -c 'enterprise.ca'

# Flush routing table and add default route

/etc/route -n -f
odmdelete -o CuAt -q "name=inet0 and attribute=route"
chdev -l inet0 -a route=net,,'0','9.101.1.70'

Definition File for the nimdef Command

The following is an example of a definition file for the nimdef command:

# Set default values.

default:
    machine_type  = standalone
    subnet_mask   = 255.255.240.0
    gateway       = gateway1
    network_type  = tok
    ring_speed    = 16
    platform      = rs6k
    machine_group = all_machines

# Define the machine "lab1"
# Take all defaults.

lab1:
# Define the machine "lab2"
# Take all defaults and specify 2 additional attributes.
# The machine "lab2" uses IPL ROM emulation, and will be added to
# the machine groups "all_machines" (by default) and "lab_machines".

lab2:
    ipl_rom_emulation  = /dev/fd0
    machine_group      = lab_machines

# Define the machine "lab3"
# Take all defaults, but do not add the machine to the
# default group.

lab3:
    machine_group=

# Define the machine "lab4"
# Take all defaults, but do not add "lab4" to the default group
# "all_machines".
# Instead add it to the groups "lab_machines" and "new_machines".

lab4:
    machine_group =
    machine_group = lab_machines
    machine_group = new_machines

# Change the default "platform" attribute.

default:
    platform = rspc

# define the machine "test1"
# Take all defaults and include a comment.

test1:
    comments = "This machine is a test machine."
