# 설치 가이드

1. 코드 내려받기

git clone https://github.com/mnot/htracr

깃허브에서 프로젝트 코드 전체를 내 컴퓨터로 내려받습니다.

cd htracr

방금 내려받은 프로젝트 폴더 안으로 이동합니다.

2. Node.js

쉬움 추천

사전 준비물

Git GitHub에서 프로젝트 코드를 내려받으려면 필요합니다.
Node.js npm 명령어를 쓰려면 Node.js가 설치되어 있어야 합니다. LTS(장기지원) 버전을 추천합니다.

npm ERR! Failed at the pcap@0.2.7 install script.

이 명령어를 터미널에 그대로 입력해 실행하세요.

✅ 명령어 실행 후 터미널에 나타나는 주소(보통 http://localhost:3000 형태)를 브라우저에서 열어보세요.

이 레포의 README에 적힌 실제 명령어를 그대로 가져왔습니다.

# htracr

htracr is a packet sniffer and visualisation tool for HTTP. It does not give
you a score, grade, or hold your hand when you're crying because your site
is so damn slow, but it will give you unparalleled insight into what's 
actually happening on the wire between your browser and the Web.

## Installing htracr

First you'll need [Node](http://nodejs.org/) and its package manager, 
[npm](http://npmjs.org/). You'll also need a modern Web browser 
(known to work: Safari 5, FireFox 4, and Chrome).

Then, htracr can be installed with npm like this:

> sudo npm -g install htracr

which will install dependencies automatically.

See 'Installation Problems?' below if you have any issues getting htracr
onto your system.

Under the covers, htracr relies upon
 [node_pcap](https://github.com/mranney/node_pcap/), 
 [Raphael](http://raphaeljs.com/), [JQuery](http://jquery.com/), 
 [optimist](https://github.com/substack/node-optimist), and 
 [formidable](https://github.com/felixge/node-formidable).

## Using htracr

htracr is designed for use on the same machine your web browser or other 
client runs on; while it's possible to run it on a server, it'll be difficult
to make sense of all of the traffic coming to a normal server.

To use htracr, start it up like this:

> htracr [listen-port]

where _listen_port_ is the port you'd like htracr to be available on. Then,
point your browser at it; e.g.:

> htracr 8000

means you should point at:

> http://localhost:8000/

On some operating systems, you may need to specify the interface to listen
on. For example:

> htracr 8000 eth0
  
and in some cases, you may need permission to listen to the device, making 
the appropriate command line something like:

> sudo htracr 8000 eth0

Then, press 'start' to start capturing HTTP traffic, and 'stop' to show it.
Currently, htracr only captures traffic on port 80.

The slider will adjust the time scale. You can use the keyboard arrows 
to navigate between packets and HTTP messages.

## Installation Problems?

### libpcap

If npm complains about problems with pcap, like this:

npm ERR! Failed at the pcap@0.2.7 install script.

it usually means that it couldn't find libpcap when building. See the
instructions here: <https://github.com/mranney/node_pcap>.

On my OSX machine, I have to build like this (becoming root first):

> CXXFLAGS=-I/opt/local/include npm -g install htracr
  
because my pcap headers are in a non-standard place (thanks to MacPorts). 
YMMV.

### npm

Older versions of npm interact strangely with optimist and htracr. If you
have other issues installing npm, try upgrading npm, then re-installing 
htracr.
