Installation

Platform Support. Support for different platforms are organized into three tiers, each with a different set of guarantees. Platforms are identified by their 'target triple' which is the string to inform the compiler what kind of output should be produced. 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.

Install Rust and Cargo

The easiest way to get Cargo is to install the current stable release of Rustby using rustup. Installing Rust using rustup will also install cargo.

On Linux and macOS systems, this is done as follows:

It will download a script, and start the installation. If everything goes well,you’ll see this appear:

On Windows, download and run rustup-init.exe. It will start the installationin a console and present the above message on success.

After this, you can use the rustup command to also install beta or nightlychannels for Rust and Cargo.

For other installation options and information, visit theinstall page of the Rust website.

Build and Install Cargo from Source

Alternatively, you can build Cargo from source.

Turns a 17 minutes Nmap scan into 19 seconds.
Find all open ports fast with RustScan, automatically pipe them into Nmap.

1. Find ports quickly using Rustscan (3 seconds at its fastest).
2. Automatically runs nmap on those ports.
3. ???
4. Profit!

_{Note This is an older gif. RustScan’s current top speed is 3 seconds for all 65k ports. This gif is 26 seconds.}

RustScans only job is to reduce the friction between finding open ports and inputting them into nmap.

• Scans all 65k ports in 8 seconds (on 10k batch size).
• Saves you time by automatically piping it into Nmap. No more manual copying and pasting!
• Does one thing and does it well. Only purpose is to improve Nmap, not replace it!
• Let’s you choose what Nmap commands to run, or uses the default.
• IPv6 Support

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?

RustScan running in 8 seconds and finding all open ports out of 65k.

📊 RustScan vs Nmap vs MassScan

You need Nmap. If you have Kali Linux or Parrot OS installed, you already have Nmap. If not, follow the nmap install guide.

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.

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 for how to fix that.

🖥️ Debian / Kali

Download the .deb file from the releases page:

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 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.

Once Docker is installed, run this command against the IP you want to target.

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.

Then we can:

🍺 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:

Install it:

🔧 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!

🦊 Community Distributions

Here are all of RustScan’s community distributions.

If you maintain a community distribution and want it listed here, leave an issue / pull request / Discord message or however you want to let us know.

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 sizerustscan -b 10 will run 10 port scans for 1 second, and then another 10 for 1 second and so on.
2. Increase timeoutrustscan -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.

Rust For Mac Os 10.10

Run these 3 commands:

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:

Mac OSMac 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 LinuxWindows 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 updatingWe 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 for more.

Rust For Mac Os Versions

🔌 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.
