nmap says every port is open

shokora · 02-16-2007, 09:25 AM

I have a problem with nmap, and i can't figure out what the cause of the problem is. I've searched on multiple forums, mailingslists and google but i couldn't find anything.

Whenever i nmap a host on the internet, it says every port is open and it can't guess the operating system. If i nmap a local host it does give a normal report, does anyone knows what the cause can be and how i can fix it? I used to use nmap really often and i find it quite irritating that it doesn't work anymore.

An example (contra-media.nl is my own site):

Code:

C:\Documents and Settings\Shokora>nmap -sS -sV -vv -O contra-media.nl

And with linux, the same results?

A firewall problem?

shokora · 02-16-2007, 10:01 AM

Linux has the same problems, it can be a firewall problem yes. I recently had a new multi-pc modem installed behind my router (linksys wrt54), any options i need to look out for?
