@Clyde Well ifconfig works just fine in Debian Stretch / Retropie 4.4
I just tested it in the linux terminal. It also seems that ip addr works as well.
So doesnt matter which one will be used. Either one will do just fine. :-)
@mitu thank you so much!
Got it to work found out that the file never fully transferred over and thats why it wasn't showing up. Also if you use filezilla to transfer files over a ethernet cable make sure you use port number 22 or it will not let you connect to the pi
