This is gonna be a little strange

i have an onboard ethernet card and a usb one.

I know both works since in windows they do, and in mandrake they each worked in different instances(as follows)

onboard was eth1 and usb was eth0 ( dunno how it got assigned)

both eth1 and eth0 got ip from dhcp but eth 0 got the following:

PING 172.20.67.1 (172.20.67.1) 56(84) bytes of data.
From 172.20.67.78 icmp_seq=1 Destination Host Unreachable
From 172.20.67.78 icmp_seq=1 Destination Host Unreachable
From 172.20.67.78 icmp_seq=1 Destination Host Unreachable
From 172.20.67.78 icmp_seq=1 Destination Host Unreachable
From 172.20.67.78 icmp_seq=1 Destination Host Unreachable
From 172.20.67.78 icmp_seq=1 Destination Host Unreachable
ping: sendmsg: Operation not permitted
From 172.20.67.78 icmp_seq=2 Destination Host Unreachable
ping: sendmsg: Operation not permitted
From 172.20.67.78 icmp_seq=3 Destination Host Unreachable
ping: sendmsg: Operation not permitted

then i tried to reinstall mandrake and then

onboard became eth0 and and usb became eth1 and then eth0 got that error before

i don't know how to fix this, anyone expereince this before? it is defeinitely a SW issue on this box... thanks in advance

Do you have iptables running?

This is typically an error that a rule in the 'output chain' of iptables blocks outgoing icmp messages.

Try (as root)
"iptables -L -n -v"

If there are any rules listed in 'output chain', especially with reference to 'eth0' that is where the trouble comes from.

You can also check /var/log/messages for any log entries related with iptables, but this does not give 100% guarantee. Blocking rules might be applied without logging.

You can delete rules with
"iptables -D OUTPUT <rulenum>"

Rule numbers start with 1.
