[Network Interfaces] So many of them, I don't understand !

    Hello,


    I run the last version of openmediavault on my DIY NAS, in which I have this motherboard : ASRock H470M-ITX/AC

    On this motherboard, I have 2 ethernets ports (1GBPS and 2,5GBPS) and a wifi card.


    But in the OMV network interface page, I don't understand, there are so many intefaces.

    There is the eno1 which is enabled and blinks when I use the 'identify' button, on which is connected my ethernet cable. Ok.


    But I wanted to simply have and display my 2 ethernet ports + my wifi card. But when I run ip a, or even when I click add, there are more than 10 interfaces.


    Could you please help me understand why, and moreover what do they represent.

    (Bonus question: how can I use my wifi card to make a wifi hotspot ?)


    Thank you for your time.

    Don't know about creating a wi-fi hotspot.

    But the long list of interfaces is typical and perfectly normal. There's the loopback interface "lo" (127.0.0.1), Docker private networks, bridge interfaces for networking between VMs and the host, etc.

    The simple answer is: don't worry about the many interfaces. Just work with the ones you know (Ethernet and wi-fi).

    Looks like the Ethernet ones are eno1 and enp2s0, and your wi-fi is wlp1s0.

    Oh okay, thank you for this simple response.


    For the wifi point, I thought I could make a bridge by using my second ethernet linked to the router + wifi card (hotspot) to let the connection go through the server without mixing this up with the other ethernet which puropose is only to manage the NAS itself.


    Idk if I'm clear or if this is even possible but I'd be looking for something like this.


    Thanks again though.
