Installed it just now - don't forget to enable incoming connections on the firewall (AFWall+) if you happen to use one - and did some experimenting, especially to find out whether it would open up the device to the deluge of ssh probing. Even though those probes will (in a sane universe) not succeed they're unwelcome anyway. I do notice the device listens on port 22 on both IPv4 and IPv6. Fortunately it is possible to change this by editing /data/ssh/sshd_config where I disabled IPv6 (not necessary in this context) and changed the listening port. You never know on which network your device will end up after all.
