# This script only checks if ports 4661-4663 are open.
# The protocol is not documented, AFAIK. It was probably 'reverse engineered'
# for mldonkey (do you read OCAML?)
# I sniffed an eDonkey connection, but could not reproduce it.
# There were some information on http://hitech.dk/donkeyprotocol.html
# but I could not use it.
