NTL Home problems


Hi,

I have installed my cable modem (NTL:home 100 - Actually Ambit USB/Ethernet modem) using Ethernet on my linux box and have used dhclient which ships with Redhat 8.0 to gain a DHCP lease.

My main problem is that when my ethernet card is being brought up during the boot it tells me that it could not bring up eth0 and determine it's ip address because the link may be missing....That's not the exact message I will get that if you need it but I know that the text of that message is given in the 'ifup' script. After booting I am then able to bring up eth0 and run dhclient which does give me a correct ip address and I can browse the net.....Not for long. Ususally when I start a reasonable size download e.g I was download the list of newsgroups from NTL the cable modem resets itself and when it has booted again has a different ip address itself rather than the usual 192.168.100.1. At this point if I reboot the modem myself it reverts back to what it should be.

On top of all this i get error messages about lo (loopback) I can't remember exactly what they are but it means that I am unable to ping 127.0.0.1

I am mainly worried about just bringing the modem up automatically without it rebooting........does anybody know how?

looks to me like you've not read the instruction manual properly.

Hello Dolbz.

Welcome to LQ.org

Try not to double post - acid's undergoing a very demanding BOFH training course and it irritates other people easily

I have a similar problem, but I'm actually doing this with an lfs system. Sounds mercenary, but that's why I'm doing it. First off, you show me your and I'll show you mine:
Code:
more /etc/sysconfig/network

HOSTNAME=localhost
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY_IF=eth0

more /etc/sysconfig/network-devices/ifconfig.eth0

DEVICE=eth0
BOOTPROTO=dhcp
onboot=yes
NETMASK=255.255.255.0
DHCP_PROG=/sbin/dhclient
The interface appears to boot up properly but the dhcp interface doesn't retrieve an IP address.
If I include that last line invoking the dhcp program (which my redhat distro doesn't appear to require) I get is a strange message about /var/state/dhcp/dhcp.leases not being writable when the ifdown script is exectuted to bring the interface down.

In the redhat distribution I believe they put their ifconfig script somewhere funky - have a look in the sysconfig directory and post them.
