Purpose

configure_network is a simple script to configure the network adapter according to the values of the nvramrc variable network-boot-arguments.

The nvramrc variable network_boot_arguments is used for WANBOOT on SPARC machines.

Language / type

Shell script

Prerequisites

The nvramrc variable network-boot-arguments must be set, e.g.:

bash-3.00$ /usr/sbin/eeprom network-boot-arguments network-boot-arguments=host-ip=192.168.1.5,router-ip=192.168.1.1,subnet-mask=255.255.255.0,hostname=v240,client-id=C0A80105,file=http://192.168.1.246/cgi-bin/wanboot-cgi

Usage

    configure_network
To use it in a boot image (e.g. for WANBOOT or for failsafe booting) copy the script to /etc/init.d and create a symbolic link in the directory /etc/rc3.d; e.g.

    root@v240:/tmp/milax# ls -l etc/rc3.d/S90configure_network     lrwxrwxrwx   1 root     root          27 Nov 9 19:32 etc/rc3.d/S90configure_network -> ../init.d/configure_network

Examples:

# ifconfig bge0 ifconfig: status: SIOCGLIFFLAGS: bge0: no such interface # eeprom network-boot-arguments network-boot-arguments=host-ip=192.168.1.5,router-ip=192.168.1.1,subnet-mask=255.255.255.0,hostname=v240,client-id=C0A80105,file=http://192.168.1.246/cgi-bin/wanboot-cgi # /tmp/milax/etc/init.d/configure_network Configuring the network ... + ifconfig bge0 plumb 192.168.1.5 netmask 255.255.255.0 broadcast + up ifconfig: SIOCSLIFNAME for ip: bge0: already exists + route add default 192.168.1.1 add net default: gateway 192.168.1.1 + set +x Configuring the nodename ... # ifconfig bge0 bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3         inet 192.168.1.5 netmask ffffff00 broadcast 192.168.1.255         ether 0:3:ba:52:7d:5

The script does nothing if the network adapter is already configured:

root@v240:/# /tmp/milax/etc/init.d/configure_network ifconfig: SIOCSLIFNAME for ip: bge0: already exists Network adapter bge0 already configured: bge0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2         inet 192.168.1.5 netmask ffffff00 broadcast 192.168.1.255         ether 0:3:ba:52:7d:5 Nothing to do here Configuring the nodename ... /etc/hosts already configured.

Configuration & Internas

Nothing special -- the script just reads the nvramrc variable network-boot-arguments and configures the network adapter with the values from this variable. The network adapter to configure is the network adapter that is configured in the nvramrc adpater "net".

Notes

The script is used in the Extended MilaX WANBOOT image:
