let me make a small clarification. The DHCP thing was a wild guess. I know
that 512 is rlogin. but the webpages of SB3100 states that a DHCP server
is running inside the modem. Also the attempt to rlogin to the modem
failed as the rlogin just waited with out any response. Here is the
relevant para as it appeared in lynx.
[X] Enable DHCP Server
The SURFboard cable modem can be used as a gateway to the Internet by
a maximum of 32 users on a Local Area Network (LAN). When the Cable
Modem is disconnected from the Internet, users on the LAN can be
dynamically assigned IP Addresses by the Cable Modem DHCP Server.
These addresses are assigned from an address pool which begins with
192.168.100.11 and ends with 192.168.100.42. Statically assigned IP
addresses for other devices on the LAN should be chosen from outside
of this range
Even though the DHCP was listed as enabled nmap did not show that. That
was why I made a wild guess ;)
Now some more info
This page provides information about the servers your Cable Modem is
using, and the computers to which it is connected.

As it can be seen, the IP of the cable interface (HFC) is 10.1.15.42 But
my first attempt to connect to port 80 was refused. May be with luck it
may be possible to map the entire Fiber-Coax lan of the provider.
