I've recently learned about ssh and have attempted to get a server running via Openssh server on windows 10, and juicessh on Android. I must be doing things completely wrong as the last time I attempted it powershell wouldn't even recognize the command "ssh". Google around I can't find any information on this specific scenario. So: 1. Is this possible? 2. If so, how do I set this up? 3. If not, what can I use to remotely access my PC and retrieve files from it to my android?
With Windows 10 Pro, you can run the RD Client on your mobile device. You'll need to turn on remote access on your computer, and possibly portforwarding if you want it to function when you're away from home.
It looks like you haven't set up an SSH client on your device. I'll assume your Windows firewall is configured correctly. Install Termux on your phone, then run apt update (or pkg update). Install SSH using apt install openssh. Then connect with the command: ssh YOURDESKTOPSLOCALIP. Alternatively, you can use RDP, telnet, or a Samba share on your PC for file access.
