Knoppix 5 have some ports close?

Hi

I tryed Knoppix 5.0 and Knoppix 5.01 and both the XMMS stop the radio streaming, anf Gmail and Hotmail account don't work, is not possible read or send messages, why?. Anyone know if Knoppix 5 have some ports close?

I was looking about that but I didn 't find it.

When I use IPTRAF to chekit, some work for a few seconds, but sudenly it CLOSE, of course when radio streaming stop too. But change the number of the port to XMMS, I don't know about ports, and I don't understand IPTRAF, obviusly I can't understand. But, I can see some ports close sudenly, why?. And I was looking about open the ports but is a very technique information, about IPTABLES and more...

Thanks
