Chris, noob here. I have JRiver on my network and just want to send music from my server to the BBB and onto my Dac using the Gizmo app. I'm getting stuck on the commands that follow Type -> nano /etc/fstab. I've entered the ip of my server and the folder of my music files but now I'm not sure if I need to enter a login and password. I guess this is where my brain is stuck. Any help is appreciated.
