    Default open ports

    I have just used nmap to scan my ip for open ports and it says that the following ports are open.

    23
    53
    80


    Should i be worried or is this just normal?

    Thanks walls

    What's your external IP address!?!?!

    haha, Just kidding. Look up the ports and figure out what's running on them.
    I felt like bending the bars back, and ripping out the window frames and eating them. yes, eating them! Leaping, leaping, leaping! Colonics for everyone! All right! You dumb*sses. I'm a mental patient. I'm *supposed* to act out!

    OMFG, you have port 53 open? Damn, you better get that one closed and fast.
    A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

    Perhaps you should:
    1) Investigate what services are associated with those ports.
    2) Attempt to connect to those ports with the proper clients/services once you know what they are.
    3) Decide how to proceed based on what you learn.

    I know I seem harsh in some of my replies. SORRY! But if you're doing something illegal or posting something that seems to be obvious BS I'm going to call you on it.

    I just when onto http://whatsmyip.org/ then used this command in nmap.

    nmap -A -v MYIPHERE

    Then it tells me that those ports are open.

    Congratulations!

    If you did -A when you should be able to answer spankdidly's question.

    To resolve your open port issue please re-read my previous post and add:

    4) Learn what nmap is for and what the switches you used tell it to do.
    5) Take an internetworking 101 course or do some reading online to understand what you get when you use whatismyip.org

    ...and for Pete's sake, close port 53. I bet if you were to put wireshark on you'd a good bit of data going on port 53.

    Well i have just seen if port 53 is open with shields up and it says its closed so, i am guessing that because i am scanning my ip and i am on the inside these ports are open to me but not the rest of internet.
