One thing which is very useful on embedded systems is to setup a zeroconf hostname so that you can access your BBB using SSH without actually knowing its IP address which may change from boot to boot. So how does this work?
- Install avahi-daemon on BBB:
$ sudo apt-get install avahi-daemon
After installing it, Ubuntu automatically starts it and enables it so that it gets launched on every boot.
- Change the hostname of BBB (default was arm for this Ubuntu image) to something meaningful like beaglebone by editing the file /etc/hostname. You can now reboot your BBB and it will be accessible on the network as beaglebone.local!
- Make sure you have nss-mdns installed on your host computer and mdns host lookup is enabled in /etc/nsswitch.conf. On Fedora, you have to install the package called nss-mdns from the repositories and change the hosts line in your /etc/nsswitch.conf file to look like below:
hosts: files myhostname mdns_minimal [NOTFOUND=return] dns
Now you should finally be able to ssh into your BBB with:
$ ssh firstname.lastname@example.org
