Files for Multiple Network Interfaces

If a machine contains more than one network interface, you must create additional /etc/hostname.interface files for the additional network interfaces. You must create these files with a text editor. The Solaris installation program does not create them for you.

For example, consider the machine timbuktu, which is shown in Figure 4–1. This machine has two network interfaces and functions as a router. The primary network interface le0 is connected to network 192.9.200. The IP address is 192.9.200.70, and its host name is timbuktu. The Solaris installation program creates the file /etc/hostname.le0 for the primary network interface and enters the host name timbuktu in the file.

The second network interface is le1. This interface is connected to network 192.9.201. Although this interface is physically installed on machine timbuktu, the interface must have a separate IPv4 address. Therefore, you have to manually create the /etc/hostname.le1 file for this interface. The entry in the file would be the router`s name, timbuktu-201.
