I just port scanned some targets with nmap ,but i seen many ports are filtered,
on some targets nmap finds and tell me the services on filtered ports,but on some secured targets it cant find the services running on filtered ports,
what should i do to find the services running on filtered ports?
also will the exploits works through filtered ports?
will it cause any problems?


Looking for some ideas...

http://www.issociate.de/board/post/8448/nmap_and_%22filtered%22_ports.html

Code:

The obvious guess is that "filtered" means that a SYN probe resulted
in neither a SYN-ACK nor a RST.

Sending a SYN probe to a port which wasn't filtered and on which no
process was listening would result in a RST.

Sending a SYN probe which gets blocked by the filtering rules will
produce the same result (e.g. no response, ICMP destination
unreachable) regardless of whether or not anything is listening on
that port.


So it's obvious, that you can't use exploits against filtered or closed ports.
You need target with open TCP port able to complete 3-way handshake.
