It appears that unless one explicitly sets all the options (AUTH_SECRET, ALLOWED_SUBNETS, KILL_SWITCH, and CONFIG_FILE) to a value (either an empty value, or a setting), entry.sh fails due to an unbound variable error. I think this needs to be documented, or fixed in the script. As currently written, it sounds like leaving them undefined results in a default setting. At least in my hands, this was not the case.
