Setting up Broadband Internet Connection-IP Spoofing:
Cable Modems and Linux Add broadband connectivity to your Linux box. Set Up Broadband Linux Getting your cable modem to work under Linux can be a daunting task with all of the different providers out there to choose from.
However, if you follow these steps, obtaining that super-fast connection in Linux will be as easy as stealing cookies from your grandma's cookie jar.
Step one Install your Ethernet card. Most cable companies will do it for you, and depending on your provider, most will install some sort of 3Com NIC. The most common NIC for anyone with an @Home installation is the 3C509B. You should compile your kernel to reflect the NIC and reboot.
When you start up your computer, you should see some variation of the following:
eth0: 3c509 at 0x220, 10baseT port, address 00 20 af a6 37 83, IRQ 5. 3c509.c:1.16 (2.2) 2/3/98 becker@cesdis.gsfc.nasa.gov.
After that, you should grab that paper that your cable provider gave you that lists the information needed to connect to its network. This list should include DNS servers, how your IP is assigned (DHCP or static), and the gateway. If you don't have this information, take a look at your networking settings in Windows.

Step two Start linuxconf. Go into Networking/Client tasks/Basic host information and enter the following items:
Config mode: It's Manual if you have a static-assigned IP address, or DHCP if you have a dynamic assigned IP address. If you don't know which one you have, ask your provider.
Host name: They should have given you a hostname, such as c324396-a.plstn1.sfba.home.com
IP Address: If you answered DHCP to the above, then you can leave this blank. If you answered Manual, then this is the IP that they gave you. It should be a series of numbers like this: 65.0.122.25
Netmask: Set it to 255.255.255.0 unless otherwise instructed.
Net device: Set this to eth0 unless you have two NICs in your machine. If you have 2, and this is the second NIC, then set this as eth1.
Step three Go to the nameserver specification section
default domain: Set this to the actual domain address. For example, plstn1.sfba.home.com would be the domain.
nameserver 1: Set this as the primary DNS IP they gave you, such as 24.4.0.26
nameserver 2: Set this as the secondary DNS IP they gave you, such as 24.7.0.26
Step four Head into the Routing and gateways section and edit the following:
Default gateway: They should have given you a gateway address.
Other Routes: Select Add, and set the gateway as the IP address that they gave your modem. The destination is the gateway that you defined earlier. The netmask is optional.
Step five Save everything and exit.
Now, we're going to assume that you have a dynamic assigned IP address. So, you need to make sure that you have the "pump" package installed. It should be already installed on your machine. However, if it's not, then you can obtain pump by clicking on this link.
Reboot your machine, and look for the following as you start up:
Starting up eth0
If you see this, you're set. Log in, do an "ifconfig," and verify that your IP and eth0 device is up and running.
