RE: nc question

I am not sure of the syntax for single ports but port ranges are expressed
as follow:

nc -n -v -w 3 -z [target] 20-250 500-600 5990-7000  

Maybe you do not need the , in between your ports.

Take care

Clement

hello friends!!

I have a query regarding netcat's usage for port scanning.

I am scanning a windows machine which has 2 ports open 80 and 3389.

c:>nc -z -v target 80,3389

It shows only port 80 open,it does not consider 3389 port as an argument...

My question is if I want to scan only known ports like 21,23,80,3389
using netcat,then how can i specify them as argument?

regards,
Vijay.
