PocketBeagle
Connected via usb. Opens up cloud9 IDE, and gives you a web server connected arduino like interface to program the AM355x CPU.
GNU\Linux Sharing internet with Pocketbeagle over USB
Had some trouble with this today. This guide: https://elementztechblog.wordpress.com/2014/12/22/sharing-internet-using-network-over-usb-in-beaglebone-black/ does NOT work. These guides are also no good: https://unix.stackexchange.com/questions/520528/sharing-internet-using-network-over-usb-in-raspberry-zero-based-on-beaglebone
You don't need to setup a bridge. It might work that way, but its not required. What works is the following:
Enable packet forwarding
Check the current packet forwarding settings:
# sysctl -a | grep forward
You will note that options exist for controlling forwarding per default, per interface, as well as separate options for IPv4/IPv6 per interface.
Enter this command to temporarily enable packet forwarding at runtime:
# sysctl net.ipv4.ip_forward=1
Edit /etc/sysctl.d/30-ipforward.conf to make the previous change persistent after a reboot for all interfaces:
/etc/sysctl.d/30-ipforward.conf
net.ipv4.ip_forward=1
Afterwards it is advisable to double-check forwarding is enabled as required after a reboot. Enable NAT With iptables
# iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE # iptables -A FORWARD -m conntrack --ctstate RELATED,ESTABLISHED -j ACCEPT # iptables -A FORWARD -i usb0 -o eth0 -j ACCEPT

At this point, you will have ip routing, but DNS isn't setup yet. To get DNS working put your preferred name server in /etc/resolv.conf
nameserver 192.168.1.1
