Hvilket program spærrer min port 20

Mener du at port 20 allerede er i brug når du f.eks. vil starte din FTP server !? Eller mener du i selve routeren ?

Har du evt. IIS installeret, for der følger jo en FTP server med, og hvis den kører så ligger den jo nok på port 20.

Ja, der er et eller andet der spærrer for port 20, hvilket vil sige at jeg kan få adgang til de fleste webhoteller ved at bruge pasv-mode. Jeg kan dog ikke "få fat" på et TDC webhotel, og jeg har slået firewall'en fra.

Jeg har installeret IIS, men kun til brug for test af ASP-sider, jeg kører ingen server-funktion.

Det jeg søger lyder selvfølgelig nem, men et lille program som kunne vise hvad der bruger hvilke porte ...synes jeg har hørt om det.

Så det er altså indefra og ud at din port 20 er lukket ? Troede du mente lokalt på din PC ;)

Lyder lidt underligt. Normalt er alt åben indefra og ud - også på de routere ISP'erne leverer.

It is extremely important for you to know what is going on behind the scenes as this will help you prevent spyware and even hacking on you computer.

Mizo - XP Netstats Bar will fit itself to the top border of your screen. You can let it hide when it losses focus, to make room for other applications. You will then be presented with the icons of the applications trying to open ports on your PC.
