==== iperf3 ====


Messung der Netzwerkgeschwindigkeit

Auf dem Server , in meinem Beispiel ein Raspberrypi, wird zuerste die Software installiert.
<code>
apt-get install iperf3
</code>

\\
Dann wird die Software als Server gestartet:
<code>
iperf3 -s

iperf3 -s
-----------------------------------------------------------
Server listening on 5201
-----------------------------------------------------------



</code>

\\
Auf einem Client wird die Verbindung getestet:
<code>
iperf3 -c servername oder ip

iperf3 -c 192.168.178.29
