Developed by Bohdan Ivashko (https://github.com/Arriven)
This is a simple distributed load generation client written in go. It is able to fetch simple json config from a local or remote location. The config describes which load generation jobs should be launched in parallel. I do not intend to copy or replace it but rather provide a simple open source option. Feel free to use it in your load tests (wink-wink)
The software is provided as is under no guarantee. I will update both the repo and this readme as I go during following days (date of writing this is 26th of February 2022, third day into russian invasion into Ukraine)
Synflood implementation is taken from https://github.com/bilalcaliskan/syn-flood and slightly patched. I couldn't just import the package as all the functionality code was in an internal package preventing import into other modules. Will figure it out better later (sorry to the owner).
go to releases page and install latest version for your os
run command in your terminal
go install github.com/Arriven/db1000n@latest
~/go/bin/db1000n
how to install docker?
https://docs.docker.com/get-docker/
make sure you've set all available resources to docker
https://docs.docker.com/desktop/windows/#resources https://docs.docker.com/desktop/mac/#resources
run d1000n
docker run --pull always ghcr.io/arriven/db1000n:latest
for experienced users, see instructions in helm/
run install script directly into the shell (useful for install through ssh)
curl https://raw.githubusercontent.com/Arriven/db1000n/main/install.sh | sh
the command above will detect the os and architecture, dowload the archive, validate it, and extract db1000n executable into the working directory. You can then run it via this command
./db1000n
Enter k8s directory
$ cd k8s-manifest
Create deployment
$ kubectl create -f ./
Scale it, if you have resources
$ kubectl scale deployment/db1000n --replicas=10 -n db1000n
Usage of /tmp/go-build781992389/b001/exe/main:
-b string
path to a backup config file in case primary one is unavailable (default "https://raw.githubusercontent.com/db1000n-coordinators/LoadTestConfig/main/config.json")
-c string
path to a config file, can be web endpoint (default "https://raw.githubusercontent.com/db1000n-coordinators/LoadTestConfig/main/config.json")
-h print help message and exit
-l int
logging level. 0 - Debug, 1 - Info, 2 - Warning, 3 - Error (default 1)
-m string
path where to dump usage metrics, can be URL or file, empty to disable
-r duration
refresh timeout for updating the config (default 1m0s)
The config is expected to be in json format and has following configuration values:
jobs
-[array]
array of attack job definitions to run, should be defined inside the root objectjobs[*]
-[object]
single job definition as json objectjobs[*].type
-[string]
type of the job (determines whhich attack function to launch). Can behttp
,tcp
,udp
,syn-flood
, orpacketgen
jobs[*].count
-[number]
the amount of instances of the job to be launched, automatically set to 1 if no or invalid value is specifiedjobs[*].args
-[object]
arguments to pass to the job. Depends onjobs[*].type
http
args:
method
-[string]
http method to use (passed directly to gohttp.NewRequest
)path
-[string]
url path to use (passed directly to gohttp.NewRequest
)body
-[object]
http payload to use (passed directly to gohttp.NewRequest
)headers
-[object]
key-value map of http headersclient
-[object]
http client config for the jobclient.tls_config
-[object]
tls config for transport (InsecureSkipVerify is true by default)client.proxy_urls
-[array]
string urls for proxies to use (chosen randomly for each request)client.timeout
-[time.Duration]
client.max_idle_connections
-[number]
tcp
and udp
shared args:
address
-[string]
network host to connect to, can be eitherhostname:port
orip:port
body
-[object]
json data to be repeatedly sent over the network
http
, tcp
, and udp
shared args:
interval_ms
-[number]
interval between requests in milliseconds. Defaults to 0 (Care, in case of udp job it might generate the data faster than your OS/network card can process it)count
-[number]
limit the amount of requests to send with this job invocation. Defaults to 0 (no limit). Note: if config is refreshed before this limit is reached the job will be restarted and the counter will be reset
syn-flood
args:
host
-[string]
host to attack, can be either DNS name or IPport
-[number]
port to attackpayload_length
-[number]
refer to original syn-flood package docsflood_type
-[string]
type of flood to send, can besyn
,ack
,synack
, andrandom
Warning: packetgen
requires root privilleges to run
packetgen
args:
host
-[string]
host to attack, can be either DNS name or IPport
-[string]
numerical value of port to attack (string to allow template generation)payload
-[string]

-[number]
tcp.urgent
-[number]

-[object]
flags for tcp (every flag has it's respective name)
Warning: slow-loris
from testconfig.json is not yet finished and may overload the app due to not handling config refreshes
Almost every leaf [string]
or [object]
parameter can be templated with go template syntax. I've also added couple helper functions (list will be growing):
random_uuid
random_int
random_int_n
random_ip
random_payload
random_mac_addr
random_port
local_ip
local_mac_addr
base64_encode
base64_decode
Please refer to official go documentation and code for these for now
