Easy Start
This section aims to show you how to use Ddosify without deep dive into its details easily.
ddosify -t target_site.com
The above command runs a load test with the default value that is 100 requests in 10 seconds.
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.
Scenario based load test
ddosify -config config_examples/config.json
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.
ddosify [FLAG]
| Flag | Description | Type | Default | Required? |
|---|---|---|---|---|
-t | Target website URL. Example: https://ddosify.com | string | – | Yes |
-n | Total request count | int | 100 | No |

Load Types
ddosify -t target_site.com -l linear
Result:

Config File
Config file lets you use all capabilities of Ddosify.
The features you can use by config file;
Usage;
ddosify -config
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 optionalThis 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 optionalThis is the equivalent of the -l flag.duration optionalThis is the equivalent of the -d flag.manual_load optionalIf you are looking for creating your own custom load type, you can use this feature. The example below says that Ddosify will run the scenario 5 times, 10 times, and 20 times, respectively along with the provided durations. request_count and duration will be auto-filled by Ddosify according to manual_load configuration. In this example, request_count will be 35 and the duration will be 18 seconds. Also manual_load overrides load_type if you provide both of them. As a result, you don’t need to provide these 3 parameters when using manual_load.“manual_load”: [
{“duration”: 5, “count”: 5},
{“duration”: 6, “count”: 10},
{“duration”: 7, “count”: 20}
]
proxy optionalThis is the equivalent of the -P flag.output optionalThis is the equivalent of the -o flag.steps mandatoryThis 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 mandatoryEach step must have a unique integer id.url mandatoryThis is the equivalent of the -t flag.protocol optionalThis is the equivalent of the -p flag.method optionalThis is the equivalent of the -m flag.headers optionalList of headers with key:value format.payload optionalThis is the equivalent of the -b flag.payload_file optionalIf you need a long payload, we suggest using this parameter instead of payload.auth optionalBasic 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
}

Ubuntu 26.04 LTS "Resolute Raccoon" was released on April 23, 2026 with Linux kernel 7.0, GNOME desktop, and standard security support until April 2031. A clean install gives you a known-good starting point on new hardware, when replacing another operating system, or when an upgrade path is not practical. This guide walks through how to install Ubuntu 26.04: downloading and verifying the ISO, writing a bootable USB drive, completing the installer, and doing the initial setup after the first boot. Before you start: You need a USB drive with at least 12 GB of free space. Back up any existing data on the target machine — the installer can erase the entire disk.

The correct timezone affects more than the clock on your screen. It drives cron job scheduling, systemd timer execution, log file timestamps, database record timing, and SSL certificate validity checks. A mismatched timezone can cause scheduled jobs to fire at the wrong hour and make log timestamps impossible to match with real-world events. This guide shows how to change timezone on Ubuntu using the timedatectl command (the recommended approach for servers and remote machines) and through the graphical Date & Time settings on desktop systems. The steps apply to all current Ubuntu releases including 24.04 and 26.04. <strong>Prerequisite:</strong> Only the root user or a user with sudo access can change the system timezone. Check the Current Timezone Before You Change It Run timedatectl with no arguments to see the active timezone and clock status: bashtimedatectl Sample output: Local…
