Yup, should do.

Just make you use the ethernet port on it for an easy life and forget about the usb.

You don't need the direct connect or whatever they call it software, well it won't work on linux anyway, just make sure they give you clear instructions particularly what address you type into your browser to initially get the connection going (can't remember what it was myself now).

Hi

I'm using NTL. When you get your installation, make sure that you install using a Windoze box connected to the DSL modem they supply so that you can run their install software. Write everything down, MAC addresses etc etc.

Then if you are running a single user system, move the ethernet card into your target linux machine (make sure that this card will install on the Linux box before doing NTL install.)

If you are setting up a network you will need a DSL router that allows you to clone or spoof the MAC address on the WAN side. Realtek do these (I use one that has WAN connection and 4 100baseT ports on it and also acts as a simple firewall and provides DHCP service.) This is important because NTL uses the initial connecting MAC address on your ethernet card to identify you to its network so you must always use the same address. On the WAN side you need to set DHCP addressing as well.

Alternatively you can set up your single Linux box as outlined above and then at a later date add another card to it and turn it into a router/firewall (you will need one with DSL) and proxy server.

HIH

Hi all,

Am a newb to all this Linux fun and games and am getting more and more confused the more and more i read.....

Basically i have ntl broadband currently shared through an XP machine with 2 other computers on the net via cat 5 cable and a hub. Themodem connects through USB as i ran their software when i got the thing. I want to replace this with Red Hat 9 (only coz i have been playing with it the last few days on my computer and don't feel ready to move onto the more "advanced" distros). Obviously this means going through a NIC for the broadband and a NIC for the rest of the network.

I have set up red hat so that it can see the other Win Xp machines on the network and also enabled it to share the internet connection if i move the cable modem to another of the win XP machines on the network. This all goes through eth0. However if i plug the modem into eth1 it fails to get the network settings on boot. Also if i do not plug the modem into eth1 onboot it still fails (is this normal). I think the network card is ok as i have tried them both individually as eth0 and they both work so that i can see the other computers on the network.

Is there some problem with the way that NTL register the cable modem to a NIC (got this from an earlier post) and because i used the USB to register NTL won't let the DHCP stuff to its magic???

Any help would be greatly appreciated.

Cheers


Nairnie

The registration of the NIC only applies to Set Top Box Broadband. On a Cable modem it holds a memory of the MAC addresses of the NIC's connected to it. If it is the case that you have reached the limit (called MAC locking) you just power down the modem for 4 hrs or so and the memory will be cleared.

Having used USB originally has no effect on any of the above. The problem could possibly be that the card isn't setup for DHCP.

Cheers phoenixus.

I will give that power down thing a go overnight.

How can i check to see if the NIC is set up for DHCP. The option is ticked in the configuration panel. Also like i said in the previous post i tested the card to see if it could connect to the rest of the network by removing the NIC that was eth0 and replacing it with this one. As it found the rest of the network surly the DHCP stuff is working??! Like i siad i am a newb so my understanding of how DHCP etc works may be a bit wrong Thus any guidance is greatly appreciated.
