3.5 (Re)Configuring a Network Card (Solaris^TM )

First of all, if you installed a new network card, let your system know it. Stop the boot process with -. In the boot prompt type boot -r to rebuild the physical mapping. Next, find the device name that corresponds to your network interface card (NIC). You can find it in the file /var/adm/messages or /etc/path_to_inst. In file /var/adm/messages, search for a line like ... PCIdevice: network@5.1, eri0, which shows the presence of a network interface at device eri0. In file /etc/path_to_inst it would appear like "/pci@1f,0/pci@1/pci@1/SUNW,hme@0,1" 1 "hme". In this case the device is hme1. Other names of devices for netowrk cards are bge, le, and ce, depending on the driver used. The trailing number says if it is the first (0) or second (1) NIC attached using this driver. Once you found the device name, type ifconfig eri0 plumb to make the device (here eri0) available for the system. Plumbing is not really necessary here, once we will reboot the system. But it is always good to test if a device can be plumbed. If now want to configure your computer for a fixed-IP LAN, do the following:

Write the hostname to the file /etc/hostname.eri0:
my_hostname

Write the following contents to the file /etc/hosts:
127.0.0.1 localhost loghost
myhost_ip my_hostname

Write the following contents to the file /etc/resolv.conf:

       domain    	        my.domain.com
       nameserver1  		ip1
       nameserver2  		ip2
       search 			my.domain.com
       search 			domain.com

Write the following contents to the file /etc/netmasks:
my_netowrk my_netmask

Write the following contents to the file /etc/nodename:
my_hostname

Write the following contents to the file /etc/defaultrouter:
ip_address_of_defaultrouter

reboot

OBSERVARTIONS:

• The field my_netowrk in the file /etc/netmasks is for your network address. Search in the internet for ``network calculator'' if you do not unterstand it.
• When Solaris^TM detects two network cards, both are set to the same MAC address by default. Also IP forwarding is enabled automatically. You can disable it by editing the file /etc/rc2.d/S69inet.
• You can also do the whole procedure with ifconfig and avoid rebooting. Try man ifconfig for more info.
