Linux TCP/IP Settings 
The instructions for setting up boot-time DHCP vary dramatically 
by distribution, so you may want to refer to your particular 
version’s documentation. 
Once you have followed the instructions for your Linux system, 
continue with 
Step 3: Establishing Communication
on page 12. 
Note:
If you have more than one network card installed, you will need to 
pick distinct Ethernet identifiers for each (eth0, eth1, eth2, and so 
forth). If you select an identifier other than eth0 for your ADSL 
modem, use that identifier throughout. 
RedHat 
Edit or create 
/etc/sysconfig/network-scripts/ifcfg-eth0 
so 
that it contains the following three lines: 
DEVICE=eth0 
ONBOOT=yes 
BOOTPROTO=dhcp 
SuSE 
Edit the file 
/etc/rc.config
; search for the variables 
NETCONFIG
, 
NETDEV_0
, and 
IFCONFIG_0
. 
Set them as follows (see the instructions in 
rc.config
): 
NETCONFIG="_0" 
NETDEV_0="eth0" 
IFCONFIG_0="dhcpclient" 
Reboot with this command: 
/sbin/shutdown -r now
. 
Debian 
Add this line to the 
file /etc/network/interfaces
: 
iface eth0 inet dhcp 
Reboot with this command: 
/sbin/shutdown -r now
.

Windows TCP/IP Settings 
How you configure your Windows computer’s network settings 
differs, depending on your operating system. Go to the section that 
corresponds to your Window’s operating system. 
Note:
If you are using a Windows computer, you do not have to 
configure the TCP/IP settings. This is because your Windows 
computer will automatically configure them for you. Only 
Windows users who are troubleshooting the 
X6
will need to verify 
the TCP/IP settings.
