    Question How do you close an open Port?

    I need to know how you close a port. I know its open because i got it scanned and so on.....I want it shut. Even after re-formatting it is still open. Is this normal? Also i have reinstalled my firewall and it has been blocking a certin someone every ten mins. I have the ip address and the port # . What can i do with this info? I want them to know I know they are the buggers that have been skrewing up my system.

    Well what OS are you running? What firewall are you using? port number? Start with these and I'll try to help.

    Hey. Which port are you talking about? If your firewall is working like it's supposed to all your ports should be "stealthed," that is, they won't show up at all. That is, unless you're running some kind of server on your computer. Who did the scan? Did you scan your own computer or did you have a friend do it, or one of the free scans on the internet? As far as finding out who the person is, I think the best you might be able to do is get "Sam Spade" or use some other tool to do a "Whois" look up on the IP address. Hopefully it will give you the person's service provider and you can complain to them. You can download Sam Spade off the internet. Just put "Sam Spade" in a search engine and you can find their site.

    To close a certain port you have to know what service is running on it and then close the service. Ex: If port 6667 (irc) is open then to close it you simply exit mIRC or what ever client your using. With some firewalls, like agnitium, you can specify how long you want to block a certain IP or even the whole subnet from your computer.

    If you are running Win2K/XP, there is always the net send command to let them know you know... ie net send <their ip addy> <message>
    or something along those lines, I don't use 2k/XP, just remember watching the command on TechTV last night, and it was kinda cool. They have to have port 139 open on their computer for it to work though.....

    Don't worry about it too much as of yet...most 'scans' that occur are just general internet 'noise', especially if it is directed at your HTTP port (80). If it happens every ten minutes, I'd guess that it's your ISP checking your connection status (this is especially true of dial-up connections).
    But your firewall(if configured properly) should probably stealth your connection on all ports...I'd be more concerned about that. You might want to go to http://grc.com/default.htm and use his ShieldsUp features to test your security.

    edit your conf files to not allow this svc and kill, restart your inetd. (if that is the related one)

    Some people have NetBEUI enabled by default in their dail up connection or network settings in win 98 for example.
    Disabling that would be a start.
