3. Connect the DCM's
NETWORK port to your network, and power
cycle it. Log in again.
4. If your network
does not use DHCP, type
gcfgdbset net.eth.0 static
to make the DCM use a static IP address instead, and set the
address with
gcfgdbset net.eth.0.netmask 255.255.255.0
gcfgdbset net.eth.0.address your-address
Here, your-address should be replaced with the IP address
you want the DCM to use. The IP address you choose must be
unique on your network.
If you are connecting the DCM to a machine on the same
network, you do not need to configure any more options at this
stage.
If your network uses DHCP, you will not need to perform this
step. Instead, ensure the DCM is also using DHCP with
gcfgdbset net.eth.0 dhcp/bootp
5. Issue the command ifconfig
The DCM will reply with technical information on its current
network setup. Each interface is listed separately. The
NETWORK port uses the interface eth0:
eth0 Link encap:Ethernet HWaddr 08:00:20:C0:FF:E2
inet addr:192.168.48.187 Bcast:192.168.48.255
Mask:255.255.255.0

If the interface is correctly set up, its IP address will be shown
after inet addr: (here, 192.168.48.187.)
