Re: ambiguity about nmap results

If I run from my laptop nmap -sT my external ip it shows me all ports
are closed.

4.62 appears as non stable in portage.

How can I measure reliably what ports are open on my laptop. I don't
have root access to remote servers to run something else than nmap
-sT. and the version there appears to be old.

If I try to run nmap on my external ip say at range 1-1024 with flag -sT I get

4.62 is the latest you can download as released.

Interesting ports on some ip .:

Not shown: 1022 closed ports
0/tcp   filtered unknown
139/tcp filtered netbios-ssn
445/tcp filtered microsoft-ds

To check myself again, I connected via ssh to some other site and from
there ran nmap -sT -p 1-1024 ip

From there I got a completely different result. Almost all the 1025
ports are open except very few.

Someone can explain me why I get such a difference?

Also, nmapyourself.com isn't run by Fyodor, so you should probably ask
the guy who runs the site to check it out.
