 # 🔭 Why RustScan?
-Why spend time running fast scans and manually copying the ports, or waiting for a 20 minute scan to finish when you can just do all 65k ports in less than a minute?
 
-![gif](pictures/8seconds.gif)
+RustScan is a modern take on the port scanner. Sleek & fast. All while providing extensive extendability to you.
 
-**RustScan running in 8 seconds and finding all open ports out of 65k.**
+Not to mention RustScan uses Adaptive Learning to improve itself over time, making it the best port scanner for **you**.

+![fast][speed-1]
+
+Speed is guaranteed via RustScan. However, if you want to run a slow scan due to stealth, that is possible too.
+
+Firstly, let's talk code.
+
+We have tests that check to see if RustScan is significantly slower than the previous version. If it is, the continuous integration fails, and we can't commit code to master unless we make it faster.
+
+[HyperFine][speed-2] is used to monitor RustScan's performance over time to answer the question, "Are we getting faster? Are we getting slower?".
+
+Every pull request is reviewed by **one** person, but more often than not, **two** people review it. We test it manually and ensure the code doesn't negatively affect performance.
+

+
+## ⚙️ Extensible
+
+![scripts][extensible-1]
+
+### _RustScan piping results into the custom Python script_
+
+RustScan has a new scripting engine that allows anyone to write scripts in most languages. Python, Lua, and Shell are all supported.
+
+Want to take your found ports and pipe them into Nmap for further analysis? That's possible. Want to run `smb-enum` if SMB is found open? Possible.
+
+The possibilities are endless -- and you can write scripts in whatever language you feel comfortable with.
+
+[Read more here][extensible-2].
+
+## 🌊 Adaptive
+
+![adaptive][adaptive-1]
+
+### _RustScan automatically fine-tunes itself to match the host OS_
+
+RustScan has a cool set of features called "Adaptive Learning". These features "learn" about the environment you are scanning and how _you_ use RustScan to **improve itself over time**.
+
+We use this umbrella term for any feature that fits this criterion. The list constantly changes, so [check out our wiki for more information][adaptive-learning].
+
+## 👩‍🦯 Accessible
+
+![fast][accessible-1]
+
+RustScan is one of the first penetration testing tools that aims to be entirely accessible.
+
+[Most penetration testing tools are not accessible][accessible-2], which negatively affects the whole industry.
+
+RustScan has continuous integration testing that aims to ensure it is accessible, and we are constantly working on ways to improve our accessibility and ensure _everyone_ can use RustScan.
 
 # 📖 Full Installation Guide
-**You need Nmap**. If you have Kali Linux or Parrot OS installed, you already have Nmap. If not, [follow the nmap install guide](https://nmap.org/download.html).
 
-The easiest way to install RustScan is to use one of the packages provided for your system, such as HomeBrew or Yay for Arch Linux.
-
-The most universal way is to use `cargo`, Rust's built in package manager (think Pip but for Rust). [Follow this guide to installing Rust & Cargo](https://doc.rust-lang.org/cargo/getting-started/installation.html).
-
-If you face any issues at all, please leave a GitHub issue. I have only tested this on Linux, so there may be issues for Mac OS or Windows.
-
-Note: sometimes Rust doesn't add Cargo to the path. Please see [this issue](https://github.com/rust-lang/rustup/issues/2436) for how to fix that.
-
-## 🖥️ Debian / Kali
-
-Download the .deb file from the releases page:
-
-[https://github.com/brandonskerritt/RustScan/releases](https://github.com/brandonskerritt/RustScan/releases)
-
-Run the commpand `dpkg -i` on the file.
-
-Note: sometimes you can double click the file to achieve the same result.
-
-## Docker :whale:
-
-Docker is the recommended way of installing RustScan. This is because:
-* It has a high open file descriptor limit, which is one of the [main problems](https://github.com/RustScan/RustScan/issues/40) with RustScan. Now you don't have to fiddle around trying to understand your OS.
-* It works on all systems, regardless of OS. Even Windows, which we don't officially support.
-* The Docker image uses the latest build from Cargo, our main source-of-truth package. This means that you will always be using the latest version.
-* No need to install Rust, Cargo, or Nmap.
-
-To install Docker, [follow their guide](https://docs.docker.com/engine/install/).
-
-**Once Docker is installed, run this command against the IP you want to target.**
-
-```
-docker run -it --rm --name rustscan cmnatic/rustscan:debian-buster rustscan 127.0.0.1
-```
-
-Note: this will scan the Docker's localhost, not your own.
-
-This will download the Docker image.
-
-Once done, you will no longer need to re-download the image (except when RustScan updates) and can use RustScan like a normal application.
-
-You will have to run this command every time, so we suggest aliasing it to something memorable.
-
-```
-alias rustscan='docker run -it --rm --name rustscan cmnatic/rustscan:debian-buster rustscan'
-```
-
-Then we can:
-
-```
-rustscan 127.0.0.1 -t 500 -b 1500 -- -A
-```
-
-## 🍺 HomeBrew
-
-**Note for Mac users** Mac OS has a very, very small ulimit size. This will negatively impact RustScan by a significant amount. Please use the Docker container, or tell RustScan to up the ulimit size on every run.
-
-Tap the brew:
-
-```
-brew tap brandonskerritt/rustscan
-```
-
-Install it:
-
-```
-brew install rustscan
-```
-
-## 🔧 Building it yourself
-
-1. Git clone the repo.
-2. Install Rust. You can do this with `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh` which I took from the Rust website https://www.rust-lang.org/tools/install
-3. cd into the Git repo, and run `cargo build --release`
-4. The binary is located at `target/release/rustscan`
-5. Symlink to the binary or something. Whatever you want!
+You can find our guide [here][install-1].

+We have 2 usage guides. [Basic Usage][usage-1] and [Things you may want to do][usage-2].
 
-```
-rustscan 1.7.1
-Fast Port Scanner built in Rust. WARNING Do not use this program against sensitive infrastructure since the specified
-server may not be able to handle this many socket connections at once. - Discord https://discord.gg/GFrQsGy - GitHub
-https://github.com/RustScan/RustScan
-
-USAGE:
-    rustscan [FLAGS] [OPTIONS] <ips>... [-- <command>...]
-
-FLAGS:
-    -a, --accessible
-    -h, --help          Prints help information
-    -q, --quiet         Quiet mode. Only output the ports. No Nmap. Useful for grep or outputting to a file
-    -V, --version       Prints version information
-
-OPTIONS:
-    -b, --batch-size <batch-size>    The batch size for port scanning, it increases or slows the speed of scanning.
-                                     Depends on the open file limit of your OS.  If you do 65535 it will do every port
-                                     at the same time. Although, your OS may not support this [default: 4500]
-        --scan-order <scan-order>    The order of scanning to be performed. The "serial" option will scan ports in
-                                     ascending order while the "random" option will scan ports randomly [default:
-                                     serial]  [possible values: Serial, Random]
-    -t, --timeout <timeout>          The timeout in milliseconds before a port is assumed to be closed [default: 1500]
-    -u, --ulimit <ulimit>            Automatically ups the ULIMIT with the value you provided
-
-ARGS:
-    <ips>...        A list of comma separated IP addresses to be scanned
-    <command>...    The Nmap arguments to run. To use the argument -A, end RustScan's args with '-- -A'. Example:
-                    'rustscan -T 1500 127.0.0.1 -- -A -sC'. This command adds -Pn -vvv -p $PORTS automatically to
-                    nmap. For things like --script '(safe and vuln)' enclose it in quotations marks \"'(safe and
-                    vuln)'\"")
-```
-
-The format is `rustscan -b 500 -T 1500 192.168.0.1` to scan 192.168.0.1 with 500 batch size with a timeout of 1500ms. The timeout is how long RustScan waits for a response until it assumes the port is closed.
-
-The batch size determines how fast RustScan is. Set it to 65k, and it will scan all 65k ports at the same time. This means at at 65k batch size, RustScan will take TIMEOUT long to scan all ports. Essentially, if timeout is 1000ms, **RustScan can scan in 1 second**.
-
-Your operating system may not support this, but it is worth it to play around and see where your open file limit is. Shortly I will be releasing a dockerised version with a much larger open file limit, so this will be possible.
-
-## ⚠️ WARNING
-
-This program, by default, scans 5000 ports at a time (5000 per second).
-
-This may cause damage to a server, or may make it incredibly obvious you are scanning the server.
-
-There are 2 ways to deal with this;
-1. Decrease batch size
-`rustscan -b 10` will run 10 port scans for 1 second, and then another 10 for 1 second and so on.
-2. Increase timeout
-`rustscan -T 5000` will mean RustScan waits 5 seconds until it scans the next ports.
-
-You can also use both of these at the same time, to make it as slow or as fast as you want. A fun favourite is 65535 batch size with 1 second timeout. Theoretically, this scans all 65535 ports in 1 second.
-
-**Please** do not use this tool against sensitive servers. It is designed mainly for Capture the Flag events, not real world servers with sensitive data.
-
-## 🚨 Thread Paniced at Main: Too Many Open Files
-This is the most common error found in RustScan.
-
-The open file limit is how many open sockets you can have at any given time.
-
-This limit changes from OS to OS.
-
-RustScan does not automatically create defaults (other than 5000) like Nmap does with their -T1, -T2 system.
-
-By figuring out for yourself the optimal batch size, you will know that RustScan is the most optimised port scanner for your system.
-
-There are 2 things you can do:
-1. Decrease batch size
-2. Increase open file limit
-
-Decreasing batch size slows down the program, so as long as it isn't too drastic, this is a good option.
-
-Run these 3 commands:
-
-```
-ulimit -a
-ulimit -Hn
-ulimit -Sn
-```
-
-They will give you an idea on the open file limit of your OS.
-
-If it says "250", run `rustscan -b 240` for a batch size of 240.
-
-Increasing the open file limit increases speed, but poses danger. Although, **opening more file sockets on the specified IP address may damage it**.
-
-To open more, set the ulimit to a higher number:
-
-```
-ulimit -n 5000
-```
-
-**Mac OS**
-Mac OS has, from what I can tell, a naturally very low open file descriptor limit. The limit for Ubuntu is 8800. The limit for Mac OS is 255!
-
-In this case, I would say it is safe to increase the open file limit. As most Linux based OS' have limits in the thousands.
-
-Although, if this breaks anything, please don't blame me.
-
-**Windows Subsystem for Linux**
-Windows Subsystem for Linux does not support ulimit (see issue #39).
-
-The best way is to use it on a host computer, in Docker, or in a VM that isn't WSL.
-
-**Automatic Ulimit updating**
-We are currently working on automatic Ulimit updating. If it is too high, it will lower itself. If it is too low, it will suggest a higher Ulimit. Watch [this issue](https://github.com/brandonskerritt/RustScan/issues/25) for more.
-
-## 🔌 Nmap Custom Flags
-To run your own nmap commands, end the RustScan command with `-- -A` where `--` indicates "end of RustScan flags, please do not parse anything further" and any flags after that will be entered into nmap.
-
-RustScan automatically runs `nmap -vvv -p $PORTS $IP`. To make it run `-A`, execute the command `rustscan 127.0.0.1 -- -A`.
-
-If you want to run commands such as `--script (vuln and safe)`, you will need to enclose it in quotations like so `--script '"(vuln and safe) or default"'`.
-
-## 🎯 Increasing speed / accuracy
-* Batch size
-
-This increases speed, by allowing us to process more at once. Something experimental I am working on is changing the open file limit. You can do this manually with `ulimit -n 70000` and then running rustscan with `-b 65535`. This _should_ scan all 65535 ports at the exact same time. But this is extremely experimental.
-
-For non-experimental speed increases, slowly increase the batch size until it no longer gets open ports, or it breaks.
-
-* Accuracy (and some speed)
-
-To increase accuracy, the easiest way is to increase the timeout. The default is 1.5 seconds, by setting it to 4 seconds (4000) we are telling RustScan "if we do not hear back from a port in 4 seconds, assume it is closed".
-
-Decreasing accuracy gives some speed bonus, but my testing found that batch size dramatically changed the speed whereas timeout did, but not so much.
+We also have documentation about our config file [here][config-file-here].

 I cannot pay you :-( But, I can place your GitHub profile on the README under `#Contributors` as a thank you! :)
+
+## Contributing development environment
+
+To ease contribution to RustScan, you can use the `contributing.Dockerfile` to create a Docker image ready to build and play with RustScan.
+To build it you just need to run:
+
+```bash
+you@home:~/RustScan$ docker build -t rustscan_contributing -f contributing.Dockerfile
+```
+
+Then you need to run the container with a volume so it can access, _with read and write permissions_, to RustScan files:
+
+```bash
+you@home:~/RustScan$ docker run -ti --rm -v "$PWD":/rustscan -w /rustscan rustscan_contributing bash
+```
+
+You can now modify RustScan files with your favorite editor, once you want to compile and test your modifications, type the following in the container prompt:
+
+```bash
+root@container:/rustscan# cargo build
+```
+
+You are now ready to use RustScan:
+
+```bash
+root@container:/rustscan# cargo run -- -b 2000 -t 5000 -a 127.0.0.1
+```
+
+You can also format, lint with `clippy` and test the code with the following commands:
+
+```bash
+root@container:/rustscan# cargo fmt
+root@container:/rustscan# cargo clippy
+root@container:/rustscan# cargo test
+```

+//! Scripting Engine to run scripts based on tags.
+//!
+//! This module serves to filter and run the scripts selected by the user.
+//!
+//! A new commandline and configuration file option was added.
+//!
+//! ## `--scripts`
+//!
+//! ### `default`
+//!
+//! This is the default behavior, like as it was from the beginning of RustScan.
+//!
+//! The user do not have to chose anything for this. This is the only script
+//! embedded in RustScan running as default.
+//!
+//! ### `none`
+//!
+//! The user have to use the `--scripts none` commandline argument or `scripts =
+//! "none"` in the config file.
+//!
+//! None of the scripts will run, this replaces the removed `--no-nmap` option.
+//!
+//! ### `custom`
+//!
+//! The user have to use the `--scripts custom` commandline argument or
+//! `scripts = "custom"` in the config file.
+//!
+//! RustScan will look for the script configuration file in the user's home
+//! dir: `home_dir/.rustscan_scripts.toml`
+//!
+//! The config file have 3 optional fields: `tag`, `developer` and `port`. Just
+//! the `tag` field will be used forther in the process.
+//!
+//! RustScan will also look for available scripts in the user's home dir:
+//! `home_dir/.rustscan_scripts` and will try to read all the files, and parse
+//! them into a vector of [`ScriptFile`].
+//!
+//! Filtering on tags means the tags found in the `rustscan_scripts.toml` file
+//! will also have to be present in the [`ScriptFile`], otherwise the script
+//! will not be selected.
+//!
+//! All of the `rustscan_script.toml` tags have to be present at minimum in a
+//! [`ScriptFile`] to get selected, but can be also more.
+//!
+//! Config file example:
+//!
+//! - `fixtures/test_rustscan_scripts.toml`
+//!
+//! Script file examples:
+//!
+//! - `fixtures/test_script.py`
+//! - `fixtures/test_script.pl`
+//! - `fixtures/test_script.sh`
+//! - `fixtures/test_script.txt`
+//!
+//! `call_format` in script files can be of 2 variants:
+//!
+//! One is where all of the possible tags `{{script}}`, `{{ip}}` and `{{port}}`
+//! are there.
+//!
+//! - The `{{script}}` part will be replaced with the scriptfile full path
+//!   gathered while parsing available scripts.
+//! - The `{{ip}}` part will be replaced with the ip we got from the scan.
+//! - The `{{port}}` part will be reaplced with the ports separated with the
+//!   `ports_separator` found in the script file
+//!
+//! And when there is only `{{ip}}` and `{{port}}` is in the format, only those
+//! will be replaced with the arguments from the scan.
+//!
+//! This makes it easy to run a system installed command like `nmap`, and give
+//! any kind of arguments to it.
+//!
+//! If the format is different, the script will be silently discarded and will
+//! not run. With the `Debug` option it's possible to see where it goes wrong.
