Hi,

Thanks for your advice.

I am testing the Knoppix CD on a RH 8.0 machine with 2 ethernet cards installed, working without problem. It took me several days to find a solution connecting to Internet without solution. The ISP is the same. Both ethernet cards have been detected. Broadband cable is connected to eth 1

I also treid disable "ACPI" on BIOS

Following is my further test per your advice;

PING 216.239.36.10 (216.239.36.10): 56 data bytes
Hanging

I also tried to stop "iptables" without solution

# /etc/init.d/iptables stop
Aborting iptables load: unknown ruleset, "inactive".

# /etc/init.d/iptables start
Aborting iptables load: unknown ruleset, "active".
