Cable modem problem.
 

Hello everyone. Please help me to solve this problem.
I'm using cable modem, in knoppix everything works fine.
I have this problems on mandriva 10.2

ifconfig eth0 81.XX.XX.25 netmask 255.255.255.0 broadcast 255.255.255.255 up
ifconfig eth0
Link encap:Ethernet HWaddr 00:07: etc
IPV6 ........... etc
inet addr:81.XX.XX.25 Bcast:255.255.255.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1


After this i'm trying to ping yahoo and as you guess no response [img]Download Failed (1)[/img]
When i'm trying to open any website in mozilla, it writes "Looking up for"
and that's all [img]Download Failed (1)[/img]


pump -i eth0 --status
it writes Error

Also I've tried to use drakconnect.
I've filled all fields with info from knoppix, everything is the same [img]Download Failed (1)[/img]
Mozilla writes "Looking up for"

Also I've tried to configure dhcp, but the result is the same.
I don't know what is the dhcp hostname ?

Here is some info from knoppix:

IP: 81.XX.XX.25
Netmask: 255.255.255.0
Broadcast: 255.255.255.255
Network: 81.XX.XX.0
Boot server 62.253.128.20
Next server 0.0.0.0
Gateway: 81.XX.XX.254
Gateways: 81.XX.XX.254
Hostname: Knoppix
Nameservers: 194.168.8.100 194.168.4.100
Renewal time: Mon Oct 31 06:34:51 2005
Expiration time: Mon Oct 31 11:24:26 2005

I've used this info to configure dhcp but the result is the same as always:
Determinig ip for ....
Failed.

And I don't know why the mac address of the modem is different on knoppix and mandriva ? It seems to be I'm getting ip then registering my mac ?

Knoppix 00:0E:9B:FA:45:FD
Mandriva 00:11:d8:57:ec:33

I don't know what to do [img]Download Failed (1)[/img]
Please help me, thanks

Re: Cable modem problem.
 

Hmm, weird... when using Mandrake 10.1 I don't have to manually configure my nic, it's picked up automagically. Can you let Mandrake auto-configure your nic?

Alternatively, can you post the output from Mandrake of ethtool eth0 for me?

Oh, and also, can you do a netstat -an?

Re: Cable modem problem.
 

Don't know about pump, but dhclient works perfectly fine with NTL. It's a bit dodgy that you're getting two totally different MAC addresses though. The only MAC address Linux should see is the MAC address of the card. If Knoppix works, I would say the MAC under Knoppix is right. You may want to check the NIC card driver module under Mandriva. If it's sending the wrong MAC address out when your dhcp client is making a request, the dhcp client is never going to get an answer sent back to it as it needs the MAC address to be correct for this.

Consider trying Ubuntu instead of Mandriva :)

Re: Cable modem problem.
 

When switching from one operating system to another, you should re-boot the cable modem. The two operating systems probably send different client_IDs in DHCP. If you could make them both use the same client_ID in DHCP requests, then you would might need to reboot the cable modem.

Hmmm... Mandriva picked up wrong driver for my modem :)

Here is knoppix info for eth0 :

eth0 Link encap:Ethernet HWaddr 00:0E:9B:FA:45:FD
inet addr:81.XX.XX.25 Bcast:255.255.255.255 Mask:255.255.255.0

Here is Mandriva info :

[root@localhost ~]# ifup eth2

[root@localhost ~]# ifconfig eth2
eth2 Link encap:Ethernet HWaddr 00:0E:9B:FA:45:FD

But it doesn't work :(

[root@localhost ~]# ping -c 1 81.XX.XX.25

[root@localhost ~]# ping yahoo.com

I've added new interface and I have chosen usbnet driver.
Well my mac address changed successfully, dhcpclient works fine, but as you saw I have no connection :(
And I'm confused with this :
inet6 addr: fe80::20e:9bff:fefa:45fd/64 Scope:Link
I don't think that this must be in my eth2 ?
May be you will recommend me what driver you are using ?
Thx for attention.

Re: Cable modem problem.
 

the inet6 address is the IPV6 address of the interface, its fine. Right, try pinging this IP 195.20.109.115 if you can ping that, the likelihood is that you need to specify the NTL DNS servers which are:

Pri: 194.168.8.100
Sec: 194.168.4.100

Re: Cable modem problem.
 

I've specified this dns servers. They are in my resolv.conf
ping results :

From 81.XX.XX.25 icmp_seq=1 Destination Host Unreachable
From 81.XX.XX.25 icmp_seq=1 Destination Host Unreachable

Re: Cable modem problem.
 

Well now is more interesting after ifup eth2 I'm running my shell as
[root@81XXXX25 ~]#
in resolv.conf only 2 nameservers, in hosts only localhost.

my ifcfg of eth2

DEVICE=eth2
DNS=194.168.8.100
DNS2=194.168.4.100
BOOTPROTO=dhcp

Can anyone help me I'm so tired of this.

Re: Cable modem problem.
 

Can anyone send me to pm what driver are you using ?
The problem was in the driver as i've mentioned when I've changed the driver to usbnet everything was beginning fine. On knoppix I've seen CDCether in the modules, but to install it on my box I need to recompile the kernel :(

How to create a new eth3 interface or change the driver to my eth0 ?

Re: Cable modem problem.
 

Solved this problem without your help.
ANYWAY THX FOR HELPING.
Moders please close the thread !!!
