netpeek

netpeek is a layer 7 sniffer. Like tcpdump, but at the application layer.

It has support for the HTTP protocol currently, so it can reconstruct the HTTP request and response from the packets flowing thru the network interface and display it with latency, packet level stats.

Some flags for filtering the packets based on host and ports:

• sport
  Source port of the packet

• dport
  Destination port of the packet

• shost
  Source host of the packet

• dhost
  Destination host of the packet

• i
  Network interface to sniff on

• protocol
  One of http, drain, dump
  -- http
  will dump the request and response on stdout
  -- drain
  will dump the packet metadata on stdout
  -- dump
  will dump the packet payload on stdout

• v
  Verbose logging

• cui (experimental)
  Use CUI (character user interface) mode

I've liberally taken inspiration and code from the JulienBreux/pody project for the CUI interface.
