Log in

Enter the user-side port (port1) or the engineer-side port (port2) for your entry, plus the passphrase you set with keydb.py.

: Either side of your pair works. Log in on port2 and you get the engineer view; either way you reach the same entry.
: The shared MAVLink passphrase for this entry -- the same one set with keydb.py, not a separate web login.
