tcpdump-style filtering

[boristian]

Hi,

i have another question.
For the project i'm working on, i need tcpdump-style packet filtering. Here is the tcpdump-call what does the job:

$ tcpdump -i en4 ether proto 0x22f0

I something like this possible with the layer2 module?

I saw there is some filter related code in src/js/capture.js. When i naive tried to pass the filter as an option in the capture.Live constructor like this:

var capture = new layer2.capture.Live('en4', {filter: 'ether proto 0x22f0'});

all i got was an error:

> Error: link-layer multicast filters supported only on ethernet/FDDI/token ring/ARCNET/802.11/ATM LANE/Fibre Channel

Greets and thanks in advance,
Christian

Filters weren't fully implemented yet (hence the missing documentation :) ). I just released a new version (0.1.6) which should support them. Let me know if you run into any issues.

Works perfect, thank you.
