Problem with SPAN port

I configured a SPAN port so I can view all network traffic with ethereal on a single computer, but no traffic is going through the SPAN port.

I cant access the internet or ping other computers on the switch from the computer connected to my SPAN port.

All ports are on the same VLAN, and it appears I am SPANning correctly:>show monitor session 1
Session 1
Type : Local Session
Source Ports:
RX Only: None
TX Only: None
Both: Fa0/1-23
Source VLANs:
RX Only: None
TX Only: None
Both: None
Source RSPAN VLAN: None
Destination Ports: Fa0/24
Encapsulation: Native
Reflector Port: None
Filter VLANs: None

The green light is on and flashes periodically on the SPAN port.

Why isnt any traffic going through the SPAN port?

how can I view all SPAN port traffic with ethereal?
