Why is Packetyzer not displaying any Adapter ?

Question

I am trying to open a new capture window to monitor incoming/outgoing traffic on a machine. But there is no network card to be seen on in the Adapter combobox like the machine didn't have one. The machine is hooked into the Lan and can be pinged and can ping. Firewall is off. What could be blocking packetyzer?

Answer 1

You didn't write what system you used. Under Linux, for example, such things happen when you start network sniffer without root privileges.
