[NTLUG:Discuss] Aberrations when connecting to Internet with Knoppix V5.0.1

[David Stanaway]

Thanks for the followup.

 From what you say, I am fairly sure that you have eth1394 loaded (The 
ethernet over firewire driver). This doesn't need anything to be 
attached, just having a firewire controller.

Looking at dmesg, or the output of lsmod should confirm this though.
