Monitoring network traffic

[zillah]

I had similar issue before

dunno what router you are using, but you may want to have a look at tools like WallWatcher ( http://www.sonic.net/wallwatcher ).
Most routers nowadays use NAT so you do not see what is happening on 'the outside' of your router. Like hacking attempts, portscans etc.
It also shows you all outgoing traffic, which machine is going out to the internet and where, and what protocol, port, etc.
If your router is supported this tool is really nice !

I use a Netgear DG834G, and the DG834GB is supported so I might be OK. I'm a bit of a n00b when it comes to networking and it looks a little complicated so I can't be arsed to set it up right now (friday night and all that). I'll look at it soon though so thanks a lot.

As for DU meter, I currently use Bandwidth Monitor Pro (and NetLimiter), but they only tell you your own bandwidth, whether on the internet or between you and another computer on the network. They don't tell you how much bandwidth anyone else is using. I'd imagine DU Meter is the same?
