Link local is a way of resolving a url name on your local network.
Some versions of Windows doesn’t support this; you may also need this if your router doesn’t do DNS assignment. Install Apple’s bonjour service to autodiscover the BBB on the network.
If you are on a more exotic network, you might have to find your BeagleBones IP address manually.
Another way is using a USB cable to connect from your computer to the BeagleBone. and check your BBBs assigned IP address with ifconfig.
Another method for connecting to your Replicape is via USB and looking at its assigned IP address with ifconfig. And then connect over the network using that information.
Note that if your computer may recognize the ethernet but not automatically set an IP that allows it to talk to the BBB - in which case you should setup a manual IP on that interface with the address 1.92.168.7.1 and netmask 255.255.255.0
If you have your BeagleBone plugged into the network, you can connect a monitor and keyboard to get the IP address assigned to the board when it boots. When the stack boots, you will see the Toggle interface (you will need to rotate your monitor to portrait mode to make it easier to work with. Assuming you’re running Kamikaze 2.0.8 or higher, you can hit Alt-F2 on the keyboard to change to another terminal, then log in with the username ubuntu and the password temppwd. Once logged in, enter ipconfig eth0 and you will see the IP address in the information. Use that IP to connect via web browser to get to OctoPrint.
