For example, consider the system timbuktu, which is shown in Figure 4–1. This system has two network interfaces. This system also functions as a router. The primary network interface le0 is connected to network 192.9.200. The IP address of the system is 126.96.36.199. The host name for the system is timbuktu. The Solaris installation program creates the /etc/hostname.le0 file for the primary network interface. The installation program also enters the timbuktu host name 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 the timbuktu system, the interface must have a separate IP address. Therefore, you have to create manually the /etc/hostname.le1 file for this interface. The entry in the file is the name of the router, timbuktu-201.
