    I know the answer to this is probably no but is anyone aware of the actual legislation that prohibits it, I'm not talking about attacking specific targets I am interested in getting an idea or the surrounding network infrostructure and generally getting used to interpreting the info.

    i don't use nmap anymore but i scanned plenty of networks about 8,9 years ago :D i don't think there are any laws against it but i could be corrected there..a good guy to ask would be probe.

    even if there were such laws in ireland, i can't see you getting arrested.

    Screaming Monkey is old skool, i'm sure he has plenty nmap scans of irelands broken IT infrastructure...well, he might know somebody with nmap logs ;)

    I would imagine it would be extremely difficult to get an arrest, never mind a conviction, for port scanning.

    thats good to know, I have only dabbled in using nmap so I would rather get a feel for what I'm doing before I go bothering anyone with noob questions, but thanks martyr I'll know who to ask if I need to,
    I suppose your main problem would be yoour isp. I'm sure ntl/chorus would not be overjoyed with me if drew attention to myself in any way. and I suppose I must have ticked some box when signing up with them that signs away any right i may have to do that kind of thing. but then again I heard its a pretty quiet program if used correctly. just have to get though my exams before i get stuck in.

    I was using it recently to learn about networking and ports. Mid use it struck me to check was it legal. (I was scanning a friends webs server) Best I can tell there is no law against it but...

    Your Isp will generally have a little sub section stating how you will be banned from their service for port scanning their infrastructure.

    So you wont be arrested but could lose your internet

    It is not illegal but it may be in violation your ISP's T&C under the section of misuse.

    Also I'd suggest you setup a lab using VMWare or box hardware that is NOT connected to the internet.
    Then use they lab to practice and monitor to see how noise your scans can be, nmap can be stealthy but only when used right.

    If your ISP sees a lot of suspicious traffic coming from your connection they may think that you are either cracking or infected with either a virus or Trojan.

    When you set up YOUR OWN NETWORK NOT CONNECTED TO THE INTERNET

    Scapy http://www.secdev.org/projects/scapy/ and friends will also help pass the time.

    Well eircom scans it's own customer's ip ranges at different ports looking for spammers. If they are under a legal right to scan your PC/Laptop - who knows!

    Not saying they do/they don't , out of interest how would that help them catch spammers ?

    I don't think it's to catch spammers but rather prevent customer's boxen (after being hacked) from being used as open mail relays and then causing all sorts of legalites for the ISP themselves as well as being added to blacklists.

    Once a companies network gets added, it can be awfully painful to get it removed.
