iperf3 as a Service

To make sure that iperf is always running when you restart your machine you can set it to run as a service

first step is to make a nologin user for the service

useradd -M iperf

then build a service file, the location depends on the Linux OS.

• REDHAT/FEDORA create/usr/lib/systemd/system/iperf3.service
• DEBIAN/UBUNTU create /etc/systemd/system/iperf3.service

[Unit]
Description="iperf3 server"
After=network.target

[Service]
Type=simple
User=iperf
ExecStart=/usr/bin/iperf3 -s
KillMode=process
Restart=on-abort

[Install]
WantedBy=multi-user.target

enable and start the service

systemctl enable --now iperf3

now since it is a service, the logs could be picked up easily in a journal

journalctl -u iperf3
