Cannot get this thing to work

[siddjain]

I cannot get this thing to work. I run it like this:

sudo http_trace -i en5 -f "tcp port 80"

but it does not capture any trace. It just gives a message Listening on en5. I have verified that en5 is the correct interface on my mac (thunderbolt ethernet port)

How can I troubleshoot/fix this?
Does tcp in filter cause it to capture http traffic?
I am interested in tracing http traffic. With port 80 I expect it to capture all internet traffic crossing my machine

Note to myself. To install run:

npm -g install http_trace

Program gets installed in /usr/local/lib/node_modules/http_trace on mac

Also note that this seems like a node 0.10 vs. 0.12 issue. The http_parser API probably only works on 0.10.
