I got your e-mail on suse-linux-e@suse.com and notice you use comcast.net with a cable modem. I just ordered suse 10 and am a comcast cable user and plan to go broadband with a comcast cable modem, at present I only have dial-up. Did you have any problems using a cable modem and could you give me any tips how you set it up in suse 10? Any help would be appreciated. TIA jozien

I have a cable modem which is a cisco and am using comcast.net. I had no problems with connecting up. I am also using a router with it with no problems. Setup was easy, set it up with windows, but it can also be done with Linux. Art

I'd suggest putting a router between the cable modem and your machine, even if you have only one machine, since that will provide a firewall. Otherwise you'll have to deal with all the firewall issues since your computer will be on the front line of the Internet battleground. Paul

Comcast cable modem gave no problems at all. I've done +/- the firewall router. Susefirewall works great in protecting your system, but the hardware firewall in front cuts down on the clutter in your log files. The only problem is that every few months the router hangs and has to be power cycled. Suse runs for years without problems (8.2 in this case). Paul Alfille

This is my set up on Comcast: I took the Coax and popped it in the Cable modem, then hooked up the cable modem to the router with a Cat5 Cable, then the router has3 other machines on it, and I didn't have to set up anything as it just works out of the box. Then I put a Cat6 cable from the router to a switch which has two more machines on it. Just don't make the mistake most newbies make, when you install don't configure, or TRY to configure the damned connection, every newbie messes up and has no idea what they are doing and thereis no reason to set it up. SUSE uses DHCP by default, just turn the machine on and go. -Allen

Some switches don't ship with firewalls on them from what my hard-ware supplier tells me. You get a "Windows" disk with the software. IIRC SMC did this with a few of their systems. So it's a good idea to ensure that the unit has a fire wall built in.

The most important aspect of putting a device between your PC and the modem is that the device takes care of NAT(Network Address Translation) from/to a public IP to/from private IPs. In case you hook up the modem directly into your PC, your PC needs to have a public IP address assigned by Comcast, let's say 24.120.10.121, which is accessible from anywhere around the world. That's why you HAVE TO set up Firewall on your machine. On the other hand, if you put a device in-between, the device MUST have two interfaces (could be logical interfaces): one has 24.120.10.121 and the other has any private IP address, let's say 192.168.1.1/255.255.255.0. And your PC can have one of IPs in the same subnet, 192.168.1.2-192.168.1.254. It can be assigned via DHCP from the device or assigned statically/manually. This case, everybody outside can try accessing the device using 24.120.10.121 but can't access your PC because of NAT on the device. Of course, if a hacker found a way to break into the device, the hacker can have many ways to attack your PC, like setting up port mapping or whatever. But the chance the hacker or viruses can attack your PC is much less than you hook up the PC to the modem. Needless to say, if you need or decide to add another PC, it would be much easier than installing another NIC into your PC to connect your second PC. Toshi

Well said. It explains just why a router is worthwhile even if there's only one computer connected to it. They're not expensive, they're very easy to install even with little knowledge, and they simplify matters enormously if you ever want to hook more than one computer to the Net. I've often wondered, though, how strong the router firewall is. Routers can be configured to allow settings from outside, though I don't think that's the default on the typical Linksys or Netgear. It's also a good idea to set the password to a non-default value, although I don't know whether that's really necessary if outside access is blocked. Anyone know the story on router hacks? Paul

Are you really talking about a switch rather than a router? I wouldn't expect a switch to provide much if any protection. As someone else pointed out, the NAT (Network Address Translation) provided by the router makes a huge difference because it makes your machine's IP address invisible to the outside world. Paul

I have used a cable modem to connect to Comcast and its predecessors for 10 years, all of which have had at least 1 Linux system on my LAN at home. The only problem with Comcast and Linux is that when you talks to a support

I use a Linksys wireless router for my in-home network.
The cable modem uses a Cat-5 connection that is standard ethernet. Some
cable modems also have USB. Don't use the USB.
