Your ifconfig shows that eth0 doesn't have an IP address. I would check your /etc/network/interfaces file.

System --> Preferences --> Network connections
Delete all connections and restart it.

Now type in terminal
$ ifconfig -a | grep 'eth'
Now it shows current activated ethernet connection name like eth0, eth1, eth2 or something like this.
Now type in terminal
$ ifconfig eth0 up
where eth0 is the current activate ethernet connection. put your ethernet connection name here.
Now try, it should work.
