Error: Sorry, I can't start the sniffer, it says 'undefined'

I just npm install -g htracr it and started with htracr 8080 then opened http://localhost:8080 in Chrome and clicked on Start

Oh, I solve the problem! @est @nobso

I traced the code of htracr, find that there are some problems of pcap, the package.json of htracr wrote "pcap": ">=0.2.8", when we run npm install，it will download pcap@2.0.1, whick changed the output format packet.payload.payload not packet.link.ip

then i modify the package.json "pcap": "1.2.0", and reinstall, it works.

by the way i downgrade the version of node to v0.10.28 and the npm to 1.4.9 to install the node-pcap, (^ - ^)

pcap seems to be a bit of a mess right now 😕 – am waiting for it to settle down.
