Ethernet: How can I check my setup?

[Guest]

I am still trying to learn about Linux:

I would be using YOPER if only I could surf the net. It works fine when I install Yoper for the 1st time: Then on subsequent reboots, I cant: Heres a litle more info incase anyone can help. BTW: T41p works with mandrake, suse and Fedora Core 2 no problem. So I guess its to do with my setup?

The laptop is being used as dual boot - XP and YOS.

Everything works fine in XP. Hardware is as follows:

The ADSL modem is a D-Link DSL-302G

The Laptops ethernet adapter is: Intel ® pro/1000 MT Mobile Connection.


So, heres the ifcfg-eth0

ONBOOT=yes
IP=
NETMASK=
BROADCAST=

----------------------------------------------------------

ifconfig:

dd@localhost ~ $ ifconfig

Any help appreciated . I am sure there should be someone here that may be able to point me in the right direction. Yes I have posted on the Yoper site before, only to be told its the "driver" ?

Any response appreciated!

The ifconfig output shows that data is transmitted and received. So the hardware works fine. Your problem is the tcp/ip setup. Make sure that you have a current DHCP lease, maybe restart dhclient.

Generic tcp/ip debugging hints:

Check the route output, make sure you have a gateway.

You have a private ip number, so the firewall rules must include ip masquerading.

Use tcpdump or ethereal to see what is happening on the wire.
