# 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
