Network analyzer software

Posted on 2004-11-12

The network I'm on is having slowness issues occasionally, on top of that I've been tasked to draw out a network map.  What are my options available for a network analyzer program.  I want someone I can use to show me the network as a whole and report on it.  Not just 1 PC at a time.  Also what tools can I use to aide in my network map drawing as It's quite difficult to trace where every single cable goes without unplugging servers and such.

    FOr your network analyzer, you could use Ethereal, wich is the best, FREE open-sourced tool on the net.. it works beautifully:

    Btw, to use ethereal, you have to to connect your computer on a HUB, because only hubs receive packets from all the networks since there is no micro-segmentation on them.. If you use it on a switch, you have to use a managable switch and enable port listening on one port (also known as SPAN or port monitoring), which copies a portion of the switch’s traffic to a specific port,  and plug your workstation using the network analyzer on it..
