Accessing cable-modem systems is tricky -- as with ppp dialups, they vary a
lot in details of hookup. Some can be a real challenge, while others are a
piece of cake.
If your problem is just DHCP, you need to install and run a package usually
called dhcpcd (for DHCP Client Daemon). There's an .rpm for Red Hat and its
ilk, and a .deb for Debian.
Or your problem may be with the physical hookup. For a Masq'd (not masked;
the term is short for Masqueraded) LAN, you want a setup roughly like the
following (addresses are illustrative):
Linux router
HUB <---> eth1 eth0 <---> cable modem <---> GATEWAY
192.168.1.0 192.168.1.1 10.1.1.23 10.1.1.1
| |
| |
NT Client Internet
192.168.1.10
You get the real eth0 address from the cable-modem ISP (probably via DHCP),
and the gateway may come as part of the DHCP lease or separately from the ISP.
Finally, SOME cable-modem boxes note the MAC (Ethernet) address of the NIC
that they connect to. IF yours is like this, it won't work with the Linux
host if it expects the NT host. Fixing this can be as easy as unpowering,
then restarting the cable modem, or it can require a call to your provider.
Just depends.
If just installing dhcpcd solves your problem, that's terrific. If not,
write again, with as much detail as you can provide.
