    Okay, I didn't know about ipconfig, thanks. I already used the command ping /?, but it doesn't tell me what ping is used for. Can anyone give a good explanation.

    Also in zonealarm, under securty and under 'local zone contents', should I have anything listed. I keep blocking my IP, is that okay?

    If you want to know specifically what the command from DOS does try:

    Or DOS commands in general (point 9 is ping):

    And from ZDNet:

    hope this helps.

    Does the Internet Provider (IP) get ........ed off when you have a firewall?

    I don't know, but my firewall keeps blocking my Internet Provider. Infact it blocks about 200 people per day, at least today so far. Many of those, about 10% are from my IP.

    Are you using ZoneAlarm? Then set your local settings to medim, and internet to high.

    Your ISP shouldn't be blocked, but you are no doubt receiving a stray packet from their servers. I wouldn't worry about that, I get those all the time.

    Yes, I downloaded Zone Alarm today. It's great. So you just block everything? Do you examing the log much to see who is trying to get in. I'm thinking of writing a C program to check the IP's for me and report to me who's trying to get in and how often.

    Don't view everything as an attack. It sometimes seems that way, but many times ZA gives you bent information.

    The idea of the firewall is to make you invisible to the world. You are not supposed to exist.... it makes you a harder target.

    If a person scans a block of IP adresses and yours is in that set, ZA will pick it up and let you know... but they are not trying to get in per say. They are only looking for services to exploit. Most of them are looing for the easy door. Webservers on port 80, ftp, telnet. If they don't even get a reply back from your computer... they pass by without a thought. That is what ZA does for you. Still you can give your IP away through other means... (like coming here for example or signing up for one of my contests) Then your existence is known... but there is a way around that too...

    Look into "A4 Proxy" If you truly want to not exist... A4 Proxy, ZA, and a hardware router like NETGEAR. That is about all you need to make even a network in your house invisible.

    I used to be really into being hidden. Now I just don't give a crap. I run a triple boot entry computer and could care less if I lose a leg of it because I have daily backups and other computers on the network. Format C... reinstall.

    p.s. You might be seeing a lot of traffic because you have a trojan. Close all internet software programs (Browser etc) and run "netstat" from the command line. If you are connected... be concerned...)

    Port 80 is your HTTP Port

    When I use netstat it gives me information but how do I know if that information is bad? What should I look for?
