You are right. Sagar can you confirm the same. On Mon, Jul 19, 2010 at 2:27 PM, Andre Pawlowski <sqall () h4des org> wrote:
This means, that nmap cannot check these ports because you are filtered. So it is possible that there is a service running and reachable from other IP-addresses. But it could also be that there is no service running.

Now, this could be because either a firewall or the scanning host is generating ICMP ports or silently dropping packets. By marking them as filtered does it mean that there could be a service running on these ports but that service is only accessible by internal users or limited public IPs and blocked for other hosts? ------------------------------------------------------------------------ Securing Apache Web Server with thawte Digital Certificate In this guide we examine the importance of Apache-SSL and who needs an SSL certificate.
