A multi-threading tool to sniff HTTP header records beyond TCP flow statistics.
MIT licensed.
- Support both offline PCAP file and live NIC sniffing
- Perform multi-threading process, whereby the tool gets higher performance in face of big tarffic volume
- Export statistics of TCP flows
- Export HTTP request/response pairs if they are present in the TCP flow
- Support JSON format output
The http-sniffer depends on other utilities:
A known issue about json-c is the unused params errors on linux platform,
you can use an alternative to solve it.
You may also need to export the library path where libjson-c.* locate, by
export LD_LIBRARY_PATH=/usr/local/lib
Run scons in root folder to compile:
$ cd http-sniffer
$ scons
Get your live interface with ifconfig in terminal, e.g. en0, then
$ ./bin/http-sniffer -i en0
Or store output flows as json
$ ./bin/http-sniffer -i en0 -o output.json
