Hi All,
Is there a way to see who is connected to your network.
Say if you have a wireless network and you need to know if someone got it right to get onto your network.
How do you monitor that and how do you prevent it?
Even on a normal network how could you monitor who is connected to your network?

I'll address the 2nd question: Your wireless network needs to be set up to accept *only* your card's MAC address as well as any member of the family. That prevents anyone else from piggy-backing.
Not too sure if this works for wireless cards to, but you can reassign the MAC address on some network cards. For wireless you want to _also_ enable WEP, with a good secret. A big long hex one like my mate has. He also does some trick whereby you won't see the AP by default. You have to have the correct settings to start or the AP is invisible to you. Don't ask me how he's done it, I don't know. As to a fixed network, it very much depends on your architecture: Hub: Listen for traffic in promiscuous mode. Switch: Tend to offer a special port (RMON) or other facilities for snooping. Some will also allow you to restrict access based on MAC address too, but it is probably open to the same dodge mentioned above. -- Steve Boddy
