wikiEthtool
Das ethtool ist ein Linuxprogramm mit dem Sie Ethernetports optimieren bzw. diagnostizieren können.
Erläuterung
Mit dem Tool ethtool kann man Netzwerkkschnittstellen auf individuelle Wünsche konfigurieren. Dabei kann man zum Beispiel die Bandbreite festlegen (Achtung: Muss bei beiden Seiten eingestellt werden) oder auf Autonegotiation (Automatische Anpassung der Bandbreite) gestellt werden. Desweiteren können folgende Informationen ausgelesen werden:
- Link Status
- PCI-Slot
- Geräte Version
- Wake on Lan
Installation
Unter Debian oder Ubuntu installieren Sie ethtool via apt:
apt install ethtool
Beispiele
Die angeführten Ausgaben beziehen sich auf ein 10 Gbit/s onboard Intel X722 Netzwerk-Interface (eno1) eines Supermicro X11DPi-NT Mainboards (BIOS Version 3.5).
