5.You now have access to the DCM's console and all of its functions. You

should change your password, if you have not done so already, with the command passwd

For full details on how you can configure the serial ports of the DCM, see Section 4.3, “Serial port configuration”.

Connecting over Ethernet

You can use a “crossover” Ethernet cable to connect the DCM directly to your computer. This has the same effect as connecting the DCM and your computer to a separate hub using standard Ethernet cables: the two machines will consitute a network segment, and each will have its own IP address on that segment. See Section 2.4, “Connecting to a local network” for details on how to configure TCP/IP on the DCM.

If your computer has two network interfaces, and one is connected to a local area network, you may be able to set up a network bridge between the DCM's segment and the rest of the network. For example, if you are using Microsoft Windows XP:

1.Connect to the DCM's console over a serial link.

2.Because you are connecting the DCM to a single computer, you will probably not be able to use DHCP. You should configure the DCM to

disable DHCP and use an IP address in a private range such as

192.168.0.x:

gcfgdbset net.eth.0 static

gcfgdbset net.eth.0.address 192.168.0.2 gcfgdbset net.eth.0.netmask 255.255.255.0

Here, 192.168.0.2 should be replaced with the IP address you want the DCM to use.

Allow a short time for the DCM to reconfigure the network.

3.On your computer, select Start → Control Panel → Network Connections. Right-click on the interface connected to the DCM, and select Properties.

4.Click on Internet Protocol (TCP/IP), then Properties.

5.Select Use the following IP address, and fill in an address on the same subnet as the DCM (e.g. 192.168.0.49). Click OK, then OK in the Connection Properties window.

6.Check that you can connect to the DCM using its new IP address by
