Are you getting concerned because you're reading something that says "eth0" when you don't have an eth0 interface? If so, I think you're being a bit too picky because the entire thing with predictable network device names means that some third party documentation writer CAN'T guess what yours will be and so has to just use a stand-in like "eth0" or "en0". You can get a list of YOUR network interfaces by opening a terminal and typing: $ ip link show It'll be one that's not "lo". If you see multiple and aren't sure, look what your default route is. $ ip route show $ ip route show default via 192.168.1.1 dev wlan0 proto dhcp src 192.168.1.193 metric 600 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.193 metric 600 It'll be the one that starts "default via…". So in the example above my default route goes through network interface "wlan0". Whatever yours ends up being, it should be that every time (again, the point of predictable network device names), so just use that. Probably ther entire rest of whatever guide you are reading will be relevant. Thanks, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
