probe for unspecified port
From: "testic" <testic () testic demon co uk>

Why is this command
 nmap.exe -v -sS -p21 -O pcgv2

sending a ping and probes to port 80 and 21?
I didn't specify port 80. What did I miss?

I would imagine that Nmaps default behaviour is to "TCP ping" a host before
scanning to determine whether or not the host is up. If you dont want this
behaviour use the -P0 switch to not ping at all.


PS Note to self: Dont request 'read reciepts' when sending to the Nmap
mailing list!
