Extracts information from Quake game servers and other game servers which use the same protocol.
Quake uses UDP packets, which because of source spoofing can be used to amplify
a denial-of-service attack. For each request, the script reports the payload
amplification as a ratio. The format used is
nmap -n -sU -Pn --script quake1-info -pU:26000-26004 -- <target>
