Specifically, when I bring the wi0 device online, as described in ifconfig(8), I can see traffic on my local wireless segment; but only one side of the traffic. I can see one side of the 'conversation' only, however; I see the HTTP requests going out but I do not see the HTTP replies, for instance. When I do a quick 'wicontrol -i wi0 -p 3', followed by 'wicontrol -i wi0 -p 1', to return it to its original state, I can now see both sides of the network traffic. Has anyone else encountered this? Is there an explanation? Is this a bug or a feature? TIA, -- richard -- Richard A Childers/KG6HAC -- Senor UNIX System & Network Administrator "Dont forget nothing."
