LOADING N0PERM…
Active measurement tool for testing maximum achievable bandwidth on IP networks, tuning TCP buffer parameters, and assessing packet loss.
A standard NETWORKING utility used across offensive reconnaissance, packet forensics, and defensive system administration.
Direct visibility into network interfaces, protocol frames, access controls, or filesystem structures without graphical overhead.
During live system triage, initial reconnaissance, forensic capture inspection, or baseline configuration auditing.
# Debian / Ubuntu
sudo apt install iperf3
# macOS
brew install iperf3Network throughput benchmarking:
- Start server daemon: iperf3 -s
- Client test (default 10s TCP): iperf3 -c 192.168.1.50
- Test UDP throughput with target bandwidth: iperf3 -c 192.168.1.50 -u -b 100M
- Multi-stream TCP test: iperf3 -c 192.168.1.50 -P 4
