    ntop

    Hi All,

    I have been playing around with this openssource tool an my linux machine, and found it very good. Thought that I would post it here.

    It is not so much a security tool, but more a network analysis tool.

    ntop is a network traffic probe that shows the network usage, similar to what the popular top Unix command does. ntop is based on libpcap and it has been written in a portable way in order to virtually run on every Unix platform and on Win32 as well.

    ntop users can use a a web browser (e.g. netscape) to navigate through ntop (that acts as a web server) traffic information and get a dump of the network status. In the latter case, ntop can be seen as a simple RMON-like agent with an embedded web interface. The use of make ntop easy to use and suitable for monitoring various kind of networks.
    It can be downloaded from here:

    I've mentioned about ntop here while discussing some other network management tools:

    Yes, I've been playing with ntop and it's cool. It's a network traffic analysis tool, it can run on win32, and that leads into a question: why did you post in *nix Security Discussions?

    Peace always,

    Another great network protocol analyzer is Ethereal and this is my personal favorite for *nix and windows.

    Source: Ethereal
    Ethereal is a free network protocol analyzer for Unix and Windows. It allows you to examine data from a live network or from a capture file on disk. You can interactively browse the capture data, viewing summary and detail information for each packet. Ethereal has several powerful features, including a rich display filter language and the ability to view the reconstructed stream of a TCP session.

    From what I understand ntop sniffs only sniffs the local segment to get it's data right? So you'd have to have sensors spread in each segment if you wanted to use it as a permanent monitoring tool?
