Linux – Troubleshooting Static IP Address with Raspberry Pi

after hours of trying various things I'm officially stumped. I can communicate with my raspberry pi via direct ethernet connection (without router or switch) from my windows box but not my linux box! What the heck is going on? Your expertise is needed in this dire situation.

I'm running the NOOBS debian on my pi. I'm trying to ssh in from Ubuntu 12.04 linux.

• I tried using both Ubuntu's networkmanager and also removing it from nm and just using ifconfig to set manual IP address – 192.168.1.2 for pi, 192.168.1.4 for ubuntu. 192.168.1.4 worked for windows box.
• I tried editing /etc/network/interfaces on ubuntu box after removing eth0 from networkmanager, rebooting etc.
• I ran dhclient eth0 -r to revoke the dhcp lease before adding my static ip.
• Tried both crossover and normal ethernet cables – either work with windows.
• Tried disabling my wireless adapter (on dhcp, 192.168.2.X network), wireless works concurrently on windows.

Output of ifconfig

I'm unable to so much as ping the raspberry pi from Ubuntu. Trying to fix this so I can ssh into it. Any and all help is appreciated. Thanks in advance!
