<H2>Network Interface Configuration</H2>
<P>
This form allows you to configure the Ethernet and FDDI interfaces
on the Internet Gateway system. The form modifies the <VAR>/etc/hosts</VAR>
configuration file, adding a hostname-to-Internet address translation
for each local address. The form also modifies the <VAR>/etc/config/netif.options</VAR>
file to enable each interface and to provide interface-to-hostname translations,
and the <VAR>/etc/config/ifconfig-*.options</VAR> file to specify the netmask
for each interface.
<P>
Use the Network Interface Configuration form to change the following
parameters:
<P>
<STRONG>Interface Up:</STRONG> This selection controls whether the system 
is able to communicate on the network to which this interface is attached. 
Select <VAR>Yes</VAR> to enable the network interface, or <VAR>No</VAR> to 
disable it. 
</P>
(Default value: No)
<P>
<STRONG>Interface Type:</STRONG> This informational field specifies
whether this is the system's primary network interface or a secondary
interface. The primary interface is typically the interface with the
lowest number on the system.
</P>
(Default value: Primary for the first network interface; secondary for 
all additional interfaces)
<P>
<STRONG>Interface Name:</STRONG> This informational field shows 
the name of this interface and the hardware type. The names are
system-specific and encode information on the type of chip that is
used to implement the hardware protocol and a count. 
</P>
(Default value: derived from system hardware query)
<P>
<STRONG>IP Address:</STRONG> Each interface on the system must be 
assigned a unique number on the Internet. Enter the Internet address 
for this network interface in dotted decimal (such as 1.2.3.4) or 
hexadecimal (such as 0x01020304) notation.
</P>
(Default value: 192.0.2.1)
<P>
<STRONG>Hostname:</STRONG> Each interface must have a unique
name. Traditionally, a name is assigned to the primary interface and
each secondary interface is assigned a numbered prefix to the primary
interface name. (For example, a primary interface is assigned the 
hostname aspen, and secondary interfaces as named gate-aspen, gate2-aspen, 
gate3-aspen, and so on). Enter the name of this network interface. Your
entry must not contain spaces or punctuation.  
</P>
(Default value: IRIS)
<P>
<STRONG>Netmask:</STRONG> The network number and host number are stored
in a single 32 bit value. The netmask determines how many bits are
considered part of the network number and how many are part of the host 
number. Specify a netmask in dotted decimal (such as 255.255.0.0) or
hexadecimal (such as 0xffff0000) notation.
</P>
(Default value: 0xffffff00)
