You may or may not find some of them useful for your use case: (1) T50 - be *really* careful with this one: - Source: https://gitlab.com/fredericopissarra/t50 (2) Yersina (can be used for DHCP stress testing) - Source: https://github.com/tomac/yersinia - Useful info for DHCP-specific stress testing: https://www.amirootyet.com/post/dhcp-dos-attack-with-yersinia-in-kali/ (3) wrk - L7 endpoint load testing - I typically use an Ansible playbook to generate artificial load from multiple source systems, which also allows you to consolidate the stdout reporting from each system - Source: https://github.com/wg/wrk -- -G On 2024-02-23 17:33, Brandon Martin wrote: > Before I go to the trouble of making one myself, does anybody happen to > know of a pre-canned program to generate realistic and scalable amounts > of broadcast/broad-multicast network background "chatter" seen on > typical consumer and business networks?
