[opensuse] Dumb question on networks and servers

So I want to use my Linux box to monitor network activity. Do I absolutely need to have the box be like a router that the other computers connect to or is just being on the network suitable to act as a server. In the past I've done routing but if I don't need to route in order to monitor, manage, and log network activity, that's awesome. Also, anyone know of how to do those three acts on opensuse 10.2 or of any third party software that will do that? Thanks all. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
