Re: Fast UDP scan

["Jamie Riden" <jamie.riden () gmail com>]

-T5 is fastest, -T3 or -T4 is probably a better compromise between
speed and accuracy - e.g.:

nmap -sU -T4 -p1-65535 -P0 xxx.yyy.zzz.aaa

(This may impact your network performance -T3 is also known as normal,
-T4 is aggressive and -T5 is 'insane'. You have been warned :)

cheers,
 Jamie
