Using the convenience script (macOS and Linux)

• The script requires root or sudo privileges to move ddosify binary to /usr/local/bin.
• The script attempts to detect your operating system (macOS or Linux) and architecture (arm64, x86, amd64) to download the appropriate binary from the releases page.
• By default, the script installs the latest version of ddosify.
• If you have problems, check common issues
• Required packages: curl and sudo

curl -sSfL https://raw.githubusercontent.com/ddosify/ddosify/master/scripts/install.sh | sh

Go install from source (macOS, Linux, Windows)

go install -v go.ddosify.com/ddosify@latest

Easy Start

This section aims to show you how to use Ddosify without deep dive into its details easily.

1. Simple load test

    ddosify -t target_site.com
   

   The above command runs a load test with the default value that is 100 requests in 10 seconds.

2. Using some of the features

    ddosify -t target_site.com -n 1000 -d 20 -p HTTPS -m PUT -T 7 -P http://proxy_server.com:80
   

   Ddosify sends a total of 1000 PUT requests to https://target_site.com over proxy http://proxy_server.com:80 in 20 seconds with a timeout of 7 seconds per request.

3. Scenario based load test

    ddosify -config config_examples/config.json
   

   Ddosify first sends HTTP/2 POST request to https://test_site1.com/endpoint_1 using basic auth credentials test_user:12345 over proxy http://proxy_host.com:proxy_port and with a timeout of 3 seconds. Once the response is received, HTTPS GET request will be sent to https://test_site1.com/endpoint_2 along with the payload included in config_examples/payload.txt file with a timeout of 2 seconds. This flow will be repeated 20 times in 5 seconds and response will be written to stdout.

Details

You can configure your load test by the CLI options or a config file. Config file supports more features than the CLI. For example, you can't create a scenario-based load test with CLI options.

CLI Flags

Load Types

Linear

ddosify -t target_site.com -l linear

Result:

Note: If the request count is too low for the given duration, the test might be finished earlier than you expect.

Incremental

ddosify -t target_site.com -l incremental

Result:

Waved

ddosify -t target_site.com -l waved

Result:

Config File

Config file lets you use all capabilities of Ddosify.

The features you can use by config file;

• Scenario creation
• Payload from a file
• Extra connection configuration, like keep-alive enable/disable logic
• HTTP2 support

Usage;

ddosify -config <json_config_path>

There is an example config file at config_examples/config.json. This file contains all of the parameters you can use. Details of each parameter;

• request_count optional

  This is the equivalent of the -n flag. The difference is that if you have multiple steps in your scenario, this value represents the iteration count of the steps.

• load_type optional

  This is the equivalent of the -l flag.

• duration optional

  This is the equivalent of the -d flag.

• proxy optional

  This is the equivalent of the -P flag.

• output optional

  This is the equivalent of the -o flag.

• steps mandatory

  This parameter lets you create your scenario. Ddosify runs the provided steps, respectively. For the given example file step id: 2 will be executed immediately after the response of step id: 1 is received. The order of the execution is the same as the order of the steps in the config file.

  Details of each parameter for a step;

  • id mandatory

    Each step must have a unique integer id.

  • url mandatory

    This is the equivalent of the -t flag.

  • protocol optional

    This is the equivalent of the -p flag.

  • method optional

    This is the equivalent of the -m flag.

  • headers optional

    List of headers with key:value format.

  • payload optional

    This is the equivalent of the -b flag.

  • payload_file optional

    If you need a long payload, we suggest using this parameter instead of payload.

  • auth optional

    Basic authentication.

    "auth": {
        "username": "test_user",
        "password": "12345"
    }

  • others optional

    This parameter accepts dynamic key: value pairs to configure connection details of the protocol in use.

    "others": {
        "keep-alive": true,              // Default false
        "disable-compression": false,    // Default true
        "h2": true,                      // Enables HTTP/2. Default false.
        "disable-redirect": true         // Default false
    }
