network-fingerprint
Capture packet request/response pairs for a port and/or IP to aid in Network protocol based Nuclei Templates creation.
Resources
Usage
▶ network-fingerprint -h
This will display help for the tool. Here are all the switches it supports.
| Flag | Description | Example |
|---|---|---|
| iface | Interface to perform capture on (default "lo0") | network-fingerprint -iface eth0 |
| ip | IP to filter packets for | network-fingerprint -ip 127.0.0.1 |
| port | Port to capture packets on | network-fingerprint -port 27017 |
Installation Instructions
network-fingerprint requires go1.15+ to install successfully and have libpcap-dev installed on the system.
To install libpcap-dev:-
▶ apt install -y libpcap-dev
▶ GO111MODULE=on go get -v github.com/projectdiscovery/network-fingerprint
Running network-fingerprint
To run the tool on a target to capture traffic on a port, just use the following command.
▶ network-fingerprint -port <port>
where <port> is the port you want to capture traffic for.
To also filter by IP while running on more common ports like 80, where there is a lot of noise, you can use the ip flag.
▶ network-fingerprint -port <port> -ip <destination-ip>
Output Format
testing@local# network-fingerprint -port 27017 -ip 127.0.0.1
