I bought a Pineapple Nano awhile back, and I can't remember what I did during the setup process, but when I tried to connect to it today, port 1471 is closed and the only available open ports are the following: 22/tcp open ssh 88/tcp open kerberos-sec 1947/tcp open sentinelsrm 3283/tcp open netassistant 5900/tcp open vnc I have tried to ssh but the password I saved seems not to be working.. Any suggestions on how to reset the Nano back to factory settings, without knowing the password ?
