acarsd-info
NSE detection rule by Brendan Coles · Same as Nmap--See https://nmap.org/book/man-legal.html
Retrieves information from a listening acarsd daemon. Acarsd decodes
ACARS (Aircraft Communication Addressing and Reporting System) data in
real time. The information retrieved by this script includes the
daemon version, API version, administrator e-mail address and
listening frequency.
