Would be really cool if this wasn't completely ancient
For now i have started with dropbear cuz it was the most annoying part of the bunch.
install the pocketbook toolchain from
https://github.com/Niluje/koxtoolchain
clone my repo from:
https://github.com/notmarek/dropbear-pocketbook
./patch.sh
./mipsbuild.sh
yay you did it the stuff is now built
copy src/dropbearmulti to your pocketbook at /mnt/secure/bin/dropbear
YAYAYY we have working dropbear with key auth and all the jazz

HAVE FUN
