Hello all -
I just did a clean install of 12.04 (server not desktop) for a home based web dev platform. "Out of the box" i cannot get any traffic in or out of eth0 (not even a ping). "lo" works just fine.
Install try 1 resulted in me trying to manually reconfigure eth0, open ports and services in ufw, etc... only to result in no joy and a suspicion that I mucked it up worse on my own... So, out of sheer "the Ubuntu gods are all powerful" I did another clean install and got back to "defaults". Still no joy. So, something in the default install configuration is blocking my eth0.
I can see packets coming in/out via ifconfig counts (below) so the physical and link layers are good. The IPs are assigned. I can ping/SSH on localhost so the app layers are good. This keeps bringing be back to some unknown unknown at the firewall.
What am I missing? Thanks
Here's the ifconfig:
