knoppix ehternet problem

[ezjab]

I've been running Knoppix 3.7 from CDROM on my
PC for about 2 months. Things were running fine until
last week when the power when out. When I rebooted the
PC, there was no connectivity to the network. When
I ran ping, I got the error message: "Network cannot be reached".

I've been assuming that the problem is with the ethernet
hardware interface, because when the PC boots up, the
ethernet looks like it starts ok as the log messages scroll by.

When I called the manufacturer, the tech support guy said
I need to check that the driver is installed ok. My understanding
is that Knoppix detects the ethernet interface at boot time and
automatically loads the driver. And if the driver was ok
on prior boots, it should be ok now.

Am I correct? Is there anything else I can do to isolate this
to hardware, or to software?

A secondary question I have is: Is the boot look stored on disk
someplace? I could not find it in /var/log and it would be useful
to be able to see the log.

Do you connect using a modem? And is there a router connected to the
modem. These tend to not work when there is a power failure or
something like that. You'll have to reboot the modem and router in that
order for the router to get the IP address.

If that doesn't work, please report the output of ifconfig on your PC.

For the logs, look at /var/log/messages and also the dmesg command.

Raghu,

Thanks for you response. No, the connection is not through a modem.

My connection is like this

phone line --> DSL modem -->
ethernet --> router --> ethernet --XXX> PC

I have inserted an 'XXX' where the ethernet connects to the
PC because that is where the problem is, assuming it is a hardware
problem, i.e. the internet interface on my PC. Or it could
be a driver problem at that point as the manufacturer suggests.
