I have a Motorola Surfboard 4200 USB cable modem on my computer (I have just purchased a new computer to be my linux box - an MSI motherboard, athalon processor.

I can't get the modem working, and really have no idea where to start - can someone please help.

Hi PB,

a mate of mine got this working fine also on my previous box, but that was during a session of way too much home brew :P

I am stuck around the CDCEther bit.

I get "CDCEther 14108 1" when I issue lsmod comand.

When I issue "modprobe CDCEther" I get nothing

and here's where the real problem is for me, - redhat nas no directory /etc/network - I can only see where the how to tells users of debian how to !!

????

Regards,

hello,
redhat keeps thier stuff in /etc/sysconfig
anywho, odds are you have need to do that. fire up redhat-config-network and select a new ethernet connection. select cdc usb for a module. odds are this will assign a DHCP address so try that. here is a pic:

else you can go into /etc/sysconfig/networking and create the scripts for ifcfg-eth1 and get it going like that.

is it significant that in tail -f /var/log/messages, when I plug in the modem I get (amongst other things)

localhost /etc/hotplug/usb.agent: setup acm CDCEther for USB product 7b2/4200/101
localhost devlabel: devlabel service started/restarted
localhost dhclient

HCPDISCOVER on eth0 255.255.255.255 port 67 interval 5
*it does this a few times*
localhost dhclient: No DHCPOFFERS received.

hummss, try assigning an static IP. it is using DHCP - right?

**dwainsworld** · 02-12-2004, 05:10 AM

I am asuming so since I see it written so many times here and there - but I am not sure what DHCP is...........

How would I asign a static IP to it?

OK PB - now it's going and you won't believe this - I had to turn the modem off for 30 seconds then turn it back on as I rebooted the linux machine .............and now for some reason It is a goer - but i am still at a loss as to why - I have done a lot of stuff today and not learned much i am afraid.

Anyone else reading this - if you have any nice SIMPLE reads in mind for me to learn how to network linux I would appreciate them.

Regards,

Dwain.
