pistol-rs

The library must be run as root (Linux, *BSD) or administrator (Windows), the stable version of rust is recommended.

Import from crates.io

[dependencies]
pistol = "^1"

On Windows, download winpcap here, then place Packet.lib from the x64 folder in your root of code. The other lib like npcap did not test by libpnet.

Cross Platform Support

libpnet bug on Windows

Bug issues: https://github.com/libpnet/libpnet/issues/707, the libpnet cannot get IPv6 address on Windows.

Therefore, until libpnet fixes this bug, Windows is not supported yet.

libpnet bug on rust nightly version

Bug issue: https://github.com/libpnet/libpnet/issues/686

Host Discovery (Ping Scanning)

The implementation of the `pistol' host discovery according to the nmap documentation.

Port Scanning Techniques and Algorithms

The implementation of the pistol port scan according to the nmap pdf and documentation.

Flood Attack

Remote OS Detection

OS Detection on IPv6?

On ipv6, the fingerprints are unreadable and meaningless to humans, see here for details, and nmap uses logistic regression to match target OS on ipv6, but the matching algorithm is quite outdated with confusing design logic.

The first is about the ST, RT and EXTRA metrics in fingerprints in detection on ipv6, these three metrics are not used at all in the code, at the same time, there is no detailed description of how ST and RT are calculated, I don't know why nmap would keep them in the final fingerprint.

The second is NI probes. In the relevant document of nmap, it describes the specific structure of NI probe, but I don't see anything about it in the code, and it seems to completely ignore this probe when do predict use logistic regression.

Furthermore, for the current mainstream operating systems, ipv6 fingerprint support is not as rich as ipv4, so try the ipv4 first.

    let src_ipv4 = Some(Ipv4Addr::new(192, 168, 72, 128));
    // If the value of `source port` is `None`, the program will generate the source port randomly.
    let src_port = None;
    // The destination address is required.

    // Test with an open port `22` and a closed port `99`.

According to the nmap documentation, the novelty value must be less than 15 for the probe result to be meaningful, so when this value is greater than 15, an empty list is returned. Same when the two highest OS classes have scores that differ by less than 10%, the classification is considered ambiguous and not a successful match.
