what's -sM

[Darxus <darxus () Op Net>]

You specified more than one type of TCP scan.  Please choose only one of
-sT, -sS, -sF, -sM, -sX, and -sN

I would like to be able to do all kinds of scans at once... like, find me
all open ports, no matter what it takes.

-sM does appear to be a valid flag... what is it ?

It looks like it always says there's no ports open...

nmap -sM localhost

Starting nmap V. 2.12 by Fyodor (fyodor () dhp com, www.insecure.org/nmap/)
No ports open for host localhost (127.0.0.1)
Nmap run completed -- 1 IP address (1 host up) scanned in 2 seconds


And I um... can't get back into my box right now because I accidentally
typed the wrong ipchains flags :)
