Install the termux app from the play store. Then type "pkg install openssh". Run the ssh server via "sshd" and kill it via "pkill sshd". Use "ifconfig -a" to discover your IP number.
Type control-C via holding the down volume and C. On your linux host you can contact the ssh server on your phone via "ssh -p 8022 192.168.0.99". However, you need to set up key authorization.
I ran ssh-keygen to generated the .ssh directory with proper permissions, but then just deleted the keys.
What I did was to copy my id_rsa.pub file (from my linux desktop) to a micro-SD card, pop that in my phone, and copy id_rsa.pub to ~/.ssh. The micro-SD card is /storage/extSdCard on my phone, but this seems to be different on every phone and android version. My authorized_keys file was empty, so I just copied id_rsa.pub to it, and I was in business.
After this, things are worlds easier because I can ssh into my phone and use a real keyboard to do things.
Use "scp -P 8022 *.tpq 192.168.0.99:" to copy map files. Things could certainly be bundled using tar, since that is available under termux already with no extra packages. Crazy.
