NTL broadband probem still!!
 

Hi everyone,
I have changed my distro from mandrake to fedora core 3.
It came with my book Linux for dummies!!lol
Anyways NTL still aint working.
I duel boot with windoze xp
I have an external cable modem connects to computer via ethernet.

The problem iam getting is the network config says eth0 is up, it says my connection is active, but I cant connect to the internet at all.
Says that it cant find google!!
I have tried ping and traceroute and such like but no joy

Is it because I installed ntl on windows and not on linux??
Is there anyway of installing ntl on linux??
If so why does the network config tell me eth0 is up and working and recieving traffic but nothing is getting out????

Please if someone can tell me anything I would be very very happy
I am not very brainy probably something simple but I think I have tried everything, and linux does work with ntl, even the website says it should!!!!!

Thanx

you can't "install" NTL anything... there is nothing to install, it's a pure ethernet delivered service. That CD doesn't do a thing. if the interface is up, i'd start by believing it... does the output of ifconfig show an eth0 there? if not, use redhat-configure-network (or whatever it's called in fedora) to configure it to request a DHCP address automatically.

i have just switched to NTL myself and did a manual configuration (no cd) which just worked. If your connection is working fine with windows then it should work okay with Linux. Try running a live distro to make sure that its not a problem with Fedora. If it is a problem with Fedora, then run system-config-network.

Yup eth0 is there,
everything is as it should be.

I am just not able to get on the internet!!!
I thought it might have been the MAC address but thats the same as in windoze!!
Its really strange!!!
I tried KNOPPIX that didnt work either!!!

could you actually provide the information we asked for, rather than just using far too many exclamation marks? what is the output of ifconfig?

Sorry Chris
My ifconfig output

Of course the MAC address is the same as Windows, its burnt onto a chip (although this can be spoofed).

What is the IP address you get from within Windows? This will more then likely be the same as the one in Linux as its the cable modem that stores the connection.

As to the comment about the CD doing nothing, that isn't all true. It does actually register the modems MAC address with NTL and allows the service to work. Without this then it won't work in Windows or Linux. It needs to be registered at least once.

You can do this manually by going to the registration address but the CD does it for you.


I have FC3 running on my Linux box dual booted with XP and I also have a cable modem.

I'm surpirsed that the IP address you have been given is a 213. address range, I thought NTLs were all 8*. addresses.


Also, check that the light is on on the network card (if you have them, some onboards don't).

If you can see it flashing or at least green then you know that is up.

Also, now that we know your ifconfig details, type route. I think this sould provide you with some routing details. Paste these into your reply.

yeah the ip address is the same
I have registered with ntl already i installed it using windows.
The internet works fine with windows, yep lights are on.

these are my routing details:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
213.105.253.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0

Sorry cant see it very well here it is again

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
213.105.253.0 * 255.255.255.0 U 0 0 0 eth0
169.254.0.0 * 255.255.0.0 U 0 0 0 eth0

Your internet looks like it is working, as the result of your ifconfig shows " RX bytes:641034 (626.0 KiB) TX bytes:2063 (2.0 KiB)" for eth0.

You could try:
ifdown eth0 and then
ifup eth0

or

ifdown eth0 and then
dhclient eth0

Is there anything relevant in /var/log/messages ?

Is there anything pointing to a nameserver in /etc/resolv.conf ?

[root@localhost ~]# ifdown eth0
[root@localhost ~]# ifup eth0

does that help?

I have done it thank u all for ur help.
I needed to put a default gateway in route!! lol
I tried before with 213.105.253.1 but it was wrong that was someones computer lol
I did some looking up and found the gateway for my ip.
DHCP used the same default address as windoze but it was wrong lol
sorry iam just babbling now
thanx for all ur help everyone
If anyone needs help to set up ntl iam here

I thought that it was going to be the routing, thats why I asked you for that information.

glad you worked it out anyway. Feels great huh ;)

yeah its cool!!!
linux is the best!!!

Downloaded the How Tos from the Linux Documentation Project before and stumbled across this:
