Wireshark-users: Re: [Wireshark-users] Connection dropping on en0 on OS X.

Actually, this is strange,

it ONLY seems to be my wireless connection when monitoring it on en1. My ethernet card works just fine. Go figure.

So, I guess the 'bug' here is that wireless drops on OS X as soon as I capture, but I can reconnect it.

Still, I'd love to know how to prevent the wireless from dropping. I thought in might have to do with permissions on my bpf devices in / dev/bpf. As it turns out, as long as the user wireshark runs under has read access, your golden.

As mentioned in the article, I can re-connect my wireless connection
and get the capture going again.

Your wireless connection is on en0?

Or your *wired* Ethernet connection on en0 drops?

(Note that, in OS X, not all adapters with names beginning with "en"
are necessarily Ethernet adapters - 802.11 adapters, in particular,
also have names beginning with "en".)
