My ISP is ntl with the cable modem plugged into the usb. I have no ethernet card so do not install any Ethernet offered. I am running Debian Sarge and have just upgraded to the 2.6.8-7 kernel.
Installing from the first Woody CD (from maxtux.co.uk £2.00) you must
1. Press F3 and type bf2.4 to install the 2.4.18-bf2.4 kernel
2. install the device driver for CDCEther (module or static)
3. select the DHCP/BOOTP option when it is offered during network setup. Don't know why but it worked a treat. Without this the system never found the MAC address of the modem and I had to add it to the script below.
4. accept installation from ftp and/or http to set up /etc/apt/sources.list
Problem: Connection keeps getting cut off. (The usb light on the modem stops blinking.) Solution - a script to reconnect:
su # change to root
# give password
cd /usr/local/bin/
vi dh
#!/bin/bash
# /usr/local/bin/dh - Script to reconnect to the internet.
#
killall -HUP dhclient # might have to add "-2.2.x" here
dhclient
ifconfig
# End
chmod 0744 /usr/local/bin/dh
dh
Now every time you type 'dh' as root it restarts the connection (OK it is a workaround but I'm learning as I go.) 'ifconfig' only confirms that you have reconnected. You can just type 'dhclient' but this multiplies the number of dhclients running and eventually your system dies for lack of memory. (Guess how I learnt that!)
Apparently the early 2.6 kernels changed the CDCEther.o module to usbnet.o (or something) but look carefully in 'make menuconfig' when rebuilding the kernel and it is still there. There is a new-fangled host-gadget set up but you oly need
CONFIG_USB_USBNET=y
and
CONFIG_USB_CDCETHER=y
whereas
CONFIG_USB_GADGET
does not seem necessary. Also kernel modules are now '.ko' at the end.
----------
Yoper uses dhcpcd and the above script does not work. You must also delete the file stored somewhere it /etc which has the pid number of dhcpcd before restarting. Also, if CDCEther is compiled as a module you may have to issue the command
insmod CDCEther
dhcpcd
to get going. Use 'locate' to find it but it is probably somewhere like /lib/modules/2.4.18-bf2.4/kernel/drivers/usb/ |

Hi paul,
I`ve just read your post about getting linux running on the ambit cable modem as supplied by ntl, I`ve read your post but you have lost me on a few points ! I`m pretty new to this but at the same time fairly logical. As suggested by linux support I have added 99 CDCEther to the /etc/devices/drivers file, this made no difference and the connection wizard still could not detect the modem. It is shown detected under the hardware link as the first root hub (this is a usb device) but I can not lead the system to locate the usb devices, I have read about this dhcp but do not know how this relates, sorry if I sound rather confused and slow but you get told and read such a lot and only a portion of it seems to make sense at the time.
cheers, all help would be greatly appreciated

Culled from http://homepage.ntlworld.com/robin.d.h.walker/cmtips/dhcp.html
New page as of 1 Sept 2002
Some Unix DHCP clients, such as dhclient (from www.isc.org), allow the client_id to be configured. Others, such as the versions of pump used by many Linux distributions, do not. However, pump-0.8.11 or higher, supplied with RedHat Linux 7.1 and downloadable from ftp.redhat.com, has a new command-line option --win-client-ident to match the Windows behaviour. Download, build and install the new version, then edit the startup script /etc/sysconfig/network-scripts/ifup to add the --win-client-ident option. Reboot, and your PC should now keep the same IP address when it boots under Linux as when it boots under Windows. [Thanks to John Stark for the multi-boot DHCP information]. |

This modem is the one leased out by ntl: in the UK with their Broadband package. I've got it running on a SuSE 7.2 distribution with the kernel upgraded to 2.4.19. You need to use DHCP with ntl:.
This can be done with
modprobe CDCEther
dhcpd
and all should work. |
