Hello,
I am connecting to my BBB running Angstrom using “ssh” either over USB using 192.168.7.2, or remotely by enabling port-forwarding on my Belkin N+ router and using the WAN IP address from whatismyip.com. I am able to ping and ssh back and fourth between the BBB and my laptop computer with no problems, but I cannot establish communication over the LAN network.
I can tell from my router that my laptop is at 192.168.2.2 and the BBB is at 192.168.2.9 (also confirmed by ifconfig on both machines). Both my laptop and the BBB can successfully ping the loopback addresses (127.0.0.1), their own IP addresses (192.168.2.2 and 192.168.2.9, respectively), the router’s IP address (192.168.2.1), a wireless printer on the network (192.168.2.5), and www.google.com, but they cannot ping/ssh with one another over LAN. My laptop is dual booted with Mac OSX 10.8 and Ubuntu 13.04 – neither OS works.
Obviously this isn’t of the utmost importance since I can access the BBB locally over USB or remotely over WAN – however I’m more curious than anything else why things aren’t working over LAN (which I assume should be easier than connecting over WAN).
Any ideas?
