Do not use ',' as delimiter for arguments, use space instead.
And put double "-v" for nc
Like
# nc -z -v -v target ssh ftp telnet sftp rpc
target [22.22.44.11] 22 (ssh) open
target [22.22.44.11] 21 (ftp) : Connection refused
target [22.22.44.11] 23 (telnet) : Connection refused
target [22.22.44.11] 115 (sftp) : Connection refused
target [22.22.44.11] 530 (courier) : Connection refused

Subject: nc question
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.
