installing a NIC card

/etc/network/interfaces seemed ok but it did have eth0, eth1 and eth2 entries.? I assume that this is due to my modprobe commands.

/etc/iftab was empty except for comments.? I filled in the mac for eth0 and now I can ping other boxes with no problems.? I still can not make Firefox work on the web.? I'll double check my gateways and possibly even try rebooting the box, but I think I may still have one more issue.

sudo modprobe 8139too

if that returns no errors, and actually works,  add 8139too on a separate
line to /etc/modules so it will load on boot:

echo "8139too" | sudo tee -a /etc/modules

or use an editor.

You presumably now have two ethernet cards in your system - you might
check to see if they are listed in /etc/iftab ( although IIRC that file no
longer exists by default) Possibly the system is still trying to use the
old card. I think you could disable the old module
in /etc/modprobe.d/blacklist , if necessary.


should tell you which modules are actually loaded
