@twobob: Yes, usbnet launches a telnetd alongside dropbear/openssh on the K2/K3/K4
. (It's actually the telnetd busybox applet (launched standalone, no inetd), with a patched login applet to allow passwordless logins. Hence why it's disabled when the wifi setting is enabled in usbnet, to avoid leaving a huge backdoor open to the four winds
).
