# Contributor Covenant Code of Conduct
## Our Pledge
In the interest of fostering an open and welcoming environment, we as
contributors and maintainers pledge to making participation in our project and
our community a harassment-free experience for everyone, regardless of age, body
size, disability, ethnicity, sex characteristics, gender identity and expression,
level of experience, education, socio-economic status, nationality, personal
appearance, race, religion, or sexual identity and orientation.
## Our Standards
Examples of behavior that contributes to creating a positive environment
include:
* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members
Examples of unacceptable behavior by participants include:
* The use of sexualized language or imagery and unwelcome sexual attention or
advances
* Trolling, insulting/derogatory comments, and personal or political attacks
* Public or private harassment
* Publishing others' private information, such as a physical or electronic
address, without explicit permission
* Other conduct which could reasonably be considered inappropriate in a
professional setting
## Our Responsibilities
Project maintainers are responsible for clarifying the standards of acceptable
behavior and are expected to take appropriate and fair corrective action in
response to any instances of unacceptable behavior.
Project maintainers have the right and responsibility to remove, edit, or
reject comments, commits, code, wiki edits, issues, and other contributions
that are not aligned to this Code of Conduct, or to ban temporarily or
permanently any contributor for other behaviors that they deem inappropriate,
threatening, offensive, or harmful.
## Scope
This Code of Conduct applies both within project spaces and in public spaces
when an individual is representing the project or its community. Examples of
representing a project or community include using an official project e-mail
address, posting via an official social media account, or acting as an appointed
representative at an online or offline event. Representation of a project may be
further defined and clarified by project maintainers.
## Enforcement
Instances of abusive, harassing, or otherwise unacceptable behavior may be
reported by contacting the project team at brandon@skerritt.blog. All
complaints will be reviewed and investigated and will result in a response that
is deemed necessary and appropriate to the circumstances. The project team is
obligated to maintain confidentiality with regard to the reporter of an incident.
Further details of specific enforcement policies may be posted separately.
Project maintainers who do not follow or enforce the Code of Conduct in good
faith may face temporary or permanent repercussions as determined by other
members of the project's leadership.
## Attribution
This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.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.
### 🥧 .deb file not working?
The .deb file only works on AMD64 CPUs. If yours is different (such as a Raspberry Pi) or the .deb file doesn't work, it is easy to build the .deb file yourself.
**Note**: It is easier to install Rust and install via Cargo, then it is to build the .deb file. But this is just in case!
1. 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
2. `cargo install rustscan` if you want the easiest method possible. Otherwise, to build the .deb file `cargo install cargo-deb`
3. Git clone this repo `git clone https://github.com/brandonskerritt/RustScan`
4. cd RustScan (into the git cloned repo) `cd RustScan`
5. Run `cargo deb`
6. Your .deb file is now located in `target/releases/Debian/`

RustScan 1.2.0
Bee https://github.com/brandonskerritt
Fast Port Scanner built in Rust
WARNING Do not use this program against sensitive infrastructure. The specified server may not be able to handle this
many socket connections at once.
USAGE:
rustscan [FLAGS] [OPTIONS] <ip> [command]...
FLAGS:
-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:
-T, --timeout <T> The timeout before a port is assumed to be close. In MS. [default: 1500]
-b, --batch <b> Increases speed of scanning. The batch size for port scanning. Depends on your open file limit
of OS. If you do 65535 it will do every port at the same time. Although, your OS may not
support this. [default: 4500]
-u, --ulimit <u> Automatically ups the ULIMIT with the value you provided.
ARGS:
<ip> The IP address to scan
<command>... The Nmap arguments to run. To use the argument -A, end RustScan's args with '-- -A'. To run
EXAMPLE: 'rustscan -T 1500 127.0.0.1 -- -A -sC'. This argument auto runs nmap {your commands}
-vvv -p $PORTS
```
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 format is `rustcan -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 ulimt (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
## 🔌 Nmap
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"'`.
**Note**: due to how Nmap behaves, sometimes you cannot SIGINT ctrl+c to end the scan and it acts like it is running in the background, but printing to STD::OUT. There is nothing I can do about this, unless I create a TTY shell for the sole purpose of running Nmap. Sorry 😓 I'll try to fix in an upcoming release. If any Rust experts want to help, please do!
## 🎯 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.
