also if you enter 'ifconfig' you should be displayed what the IP address of the modem is. If not you can set it.
At the /# Linux prompt, enter the following command to view the interface configurations: ifconfig The interface configurations are displayed. 2 Annotate what is displayed as the first interface (ixp0 or ixp1); this information is needed in the following steps to configure the IP address and cabling. What follows after the inet addr and Mask fields under the first listed interface is the iNFINITI unitís IP address and subnet mask. 3 If a valid/correct IP address and subnet mask were displayed in Step 1, skip to Step 4. If a valid IP address and subnet mask is not present, configure it by entering the command: ifconfig <interface> <ip address> netmask 255.255.255.0 where: interface = ixp0 or ixp1 (as noted in Step 2) ip address = desired address (192.168.0.1, for example) Note: Changing the IP address using this method is temporary; it will be overwritten by the IP address configured in the Options file when the file is read, which occurs during reboot at the end of this document. 4 Enter the following command again, to confirm the interface configurations: ifconfig Note: Anotate what is now displayed as the IP address (inet addr) of the first interface; this information is needed in later procedure steps. 5 Turn on the SSH daemon by entering the following console command: service sshd start
I believe there is also a command to view the routes in the modem, you might have to alter (default gateway) this so you gain access to it.
