If you are not using DHCP, the IP address shown should match the static IP address which you

entered during the

netconfig

procedure. If so, log in as “root” at the login prompt and check the

other configuration parameters using

ifconfig

:

Sonoma D12 CDMA(root@host:~)-> ifconfig

Pay particular attention to the settings shown for

eth0

and

eth1

, in particular the

Mask

: setting,

which should match that which is appropriate for your network. Now check the remaining configura-

tion parameters using

route

:

Sonoma D12 CDMA(root@host:~)-> route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default 192.168.1.1 0.0.0.0 UG 1 0 0 eth0
loopback * 255.0.0.0 U 0 0 0 lo
localnet * 255.255.255.0 U 0 0 0 eth0
192.168.5.0 * 255.255.255.0 U 0 0 0 eth1

Here you are interested in the default gateway address. It should match the appropriate one for your

network. If so, then the Ethernet interface of your Sonoma has been successfully configured to oper-

ate on your network and you are ready to check operation of the Sonoma over the network. If not,

you should recheck your configuration and/or repeat the

netconfig

procedure.

If you have configured a nameserver(s) for your network, you may check that by issuing this com-

mand:

Sonoma D12 CDMA(root@host:~)-> cat /etc/resolv.conf
search your.domain
nameserver 192.168.1.1
nameserver 192.168.1.2
