Re: Fast UDP scan

-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

Hi Group:

Is there a way to increase speed of UDP scan?

I'm running a full UDP scan since 3 days on 3 IP
addresses and it is still not complete.

I gave following command:

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

One way I can think of is is running parallel nmap
scans by dividing ports like:

nmap -sU -p1-30000 -P0 xxx.yyy.zzz.aaa
nmap -sU -p30000-65535 -P0 xxx.yyy.zzz.aaa

Would appreciate some inputs on this.

Regards
