Re: Portscanner für Port 5800 und 5900 gesucht

Hallo Thomas,


jetzt hat es doch geklappt.
Bei folgendem Befehl erhalte ich folgende Meldung:


Befehl:
nmap -p 5900 frank.dyndns.org

Meldung:
Starting Nmap 4.68 ( http://nmap.org ) at 2008-08-20 21:36 Mitteleuropäische Sommerzeit
Interesting ports on p5B13F37F.dip.t-dialin.net (91.19.243.127):
PORT STATE SERVICE
5900/tcp open vnc

Nmap done: 1 IP address (1 host up) scanned in 0.534 seconds


5900/tcp open vnc
Der Port ist also offen
--------------------------------------------------------------------

Auch den Prot 5901 habe ich im FritzRouter SL ebenso freigebeben wie den 5900. (System Vista Ultimate Firewall deaktiviert)


Befehl:
nmap -p 5901 frank.dyndns.org

Meldung:
Starting Nmap 4.68 ( http://nmap.org ) at 2008-08-20 21:38 Mitteleuropäische Sommerzeit
Interesting ports on p5B13F37F.dip.t-dialin.net (91.19.243.127):
PORT STATE SERVICE
5901/tcp filtered vnc-1

Nmap done: 1 IP address (1 host up) scanned in 0.654 seconds


Dieser Port ist allso nicht offen, oder was bedeutet "filtered"?
5901/tcp filtered vnc-1

--------------------------------------------------------------------


Frage 2

Wenn ich im Dosfenster Start/Ausführen/cmd eingebe

und dort
ping frank.dyndns.org
erhalte ich folgende Meldung
0% Verlust.

Wenn ich aber
ping frank.dyndns.org:5900 eingebe erhalte ich folgende Meldung

"Pinganforderung konnte HOst "frank.dyndns.org:5900" nicht finden Überprüfen Sie den Namen und versuchen Sie es erneut"


Frage:
Kann ich mit Ping keine einzelnen Ports am eigenen Rechner anpingen?

Oder ist die Befehlszeile falsch?


Vielen Dank
Frank
