i was wondering if anyone knew any good network monitoring software
You looking for something free I assume?
I know there are a couple pieces of commercial software that have a limited free version.

yeah i was looking for something that is free. i know that alot of them you have to pay for
The only free, open source software Im familiar with is OpenNMS, but Im sure there have to be some others.
What exactly on the network do you want to monitor? Your computers? The traffic? Route-tables?
For monitoring service up / down status, use [url=https://www.icinga.org/]Icinga[/url] (community fork of Nagios). For graphing things like load or network usage, use [url=http://www.cacti.net/]Cacti[/url]. Both have a steep learning curve, but once you get the hang of them they're amazingly powerful.
i found a propgram thats decent its called prtg network monitor
... What exactly are you trying to monitor?

tcpdump - [URL]http://linux.about.com/library/cmd/blcmdl8_tcpdump.htm[/URL] - found in practically every Linux/Unix repo out there and the majority of network appliances (firewalls, managed switches, routers etc). Very versatile, lightweight and does exactly what he wants - captures in/outbound packets through a network interface.
tshark - [URL]http://www.wireshark.org/docs/man-pages/tshark.html[/URL] - very similar to tcpdump in that it performs (almost) the same role, but this is developed by the Wireshark developers (read more on that below). This is a good choice if you have little/no prior networking knowledge.
[B]Both of the above tools run on Linux - I am unsure about Windows variants, but I am positive they do exist. If you are running Windows and want a GUI to look at, then read on..[/B]
Wireshark - [URL]http://www.wireshark.org/[/URL] - the "go to" packet analyzer for many network admins. It allows parsing and viewing of packet data in either real time (as it's being captured) or from a capture file (like that captured from tcpdump/tshark above) and has a powerful filtering engine to parse out patterns in the packets. I'd recommend this combined with one of the above - in combination the two make a very powerful packet analysis suite for almost any operating system and support online is abundant.
