I did start Knoppix 3.7 from CD and had no problems configuring a DSL network connection using ppoeconf. and getting it started with pon dsl-provider. Then I did a HDD install and tried again. ppoeconf found the eth0 device, but at the next step the configuration failed, indicating that there is no connection or the connection used by some other process.

I tried that as user as well as root, with the same result.

Also even inserting the CD again even without myconfig, but I ended up with the same error.

Under Windows the network still works fine. So I desperately had to switch back and look in the web for help:

I also trid netcardconfig, but without success.

Any ideas. Thany a lot in advance.
