    Port monitoring

    Hello All,
    Does anyone know of a good method to monitor TCP and UDP port traffic in real time? If there is something free out there, that would be ideal.

    Thanks,
    Mark

    You could use a packet capturing protocol analyzer like Ethereal (http://www.ethereal.com/), but it tends to be information overload unless you figure out how to write better filters than I can.

    Jefferson,

    I use Ethereal *every* time I need to monitor traffic, and have never had a problem. I suppose you're monitoring more traffic than me, but for TCP/UDP (and especially if you know the ports you're targeting) I believe Ethereal is nothing to be afraid of. I haven't made it any farther in their filters than modifying their predefined ones....would you care to share some examples of some of your filters, and explaining what you're trying to capture?

    I also use Ethereal whenever I want to capture and analyse network traffic, it does a great job of interpreting stuff for you.

    There's a Network Monitor 3.1 beta out there somewhere in Microsoft-land, but even my fairly enthusiastic (but incompetent) Googling

    Yes, I got to connect.microsoft.com (by several routes!), but I couldn't find the actual link to download the NM 3.1 beta...

    Guess you'll have to sign in, and then be a beta tester/part of that particular project, as with everything at "connect".

    Re: Port monitoring

    Jeremy, I've been traveling, so didn't see your post until now. I generally am trying to look only at a particular host's traffic, which I can do with an IP address. Usually everything else I try gives zero results. I must not have found the tutorial. <img src=/S/sad.gif border=0 alt=sad width=15 height=15> Fortunately, I need it quite rarely.
