RustScan: Find all open ports fast with Rustscan
RustScan
The Modern Port Scanner. Find ports quickly (3 seconds at its fastest). Run scripts through our scripting engine (Python, Lua, Shell supported).
✨ Features
- Scans all 65k ports in 3 seconds.
- Full scripting engine support. Automatically pipe results into Nmap, or use our scripts (or write your own) to do whatever you want.
- Adaptive learning. RustScan improves the more you use it. No bloated machine learning here, just basic maths.
- The usuals you would expect. IPv6, CIDR, file input and more.
- Automatically pipes ports into Nmap.
🔭 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?
RustScan running in 8 seconds and finding all open ports out of 65k.
📊 RustScan vs Nmap vs MassScan
| Name | RustScan | Nmap | Masscan |
|---|---|---|---|
| Fast | ✅ | ❌ | ✅ |
| Actually useful | ❌ | ✅ | ❌ |
| Realizes it’s not useful and pipes the only useful data into the only useful port scanner | ✅ | ❌ | ❌ |
🎯 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”.
