# Netgraph

Netgraph is a packet sniffer tool that captures all HTTP requests/responses, and display them in web page.

![Screenshot](https://raw.githubusercontent.com/ga0/netgraph/master/screenshot.png)

You can run Netgraph in your linux server without desktop environment installed, and monitor http requests/responses in your laptop's browser.

## Compile, Install, Run

      1. go get github.com/ga0/netgraph

      2. run $GOPATH/bin/netgraph -i INTERFACE -p PORT

      3. open the netgraph web page in your browser (for example: http://localhost:9000, 9000 is the PORT set in step 2)

      Windows user need to install winpcap library first.

## Options

      -bpf string

            Set berkeley packet filter (default "tcp port 80")

      -i string

            Listen on interface, auto select one if no interface is provided

      -input-pcap string

            Open a pcap file

      -o string

            Write HTTP requests/responses to file, set value "stdout" to print to console

      -output-pcap string

            Write captured packet to a pcap file

      -output-request-only

    	      Write only HTTP request to file, drop response. Only used when option "-o" is present. (default true)

      -p int

            Web server port. If the port is set to '0', the server will not run.  (default 9000)

      -s	Save HTTP event in server

      -v	Show verbose message (default true)

Example: print captured requests to stdout:

      $ ./netgraph -i en0 -o=stdout
