Why does proxmox have 2 ip address?

[IlyaP]

Hello, I have the same question. Proxmox with Home Assistant installed has three IP addresses on the local network. Is this normal, or should I disable one of the interfaces?

Morning, you get what you Setup. please see your data under your network Setup source directory.

Can you explain in more detail where this directory is located?

No, please read the post #21.

As shown in the screenshot look into the files in /etc/network/interfaces.d/

This happens if you initially allowed the host to come up in DHCP mode, then reconfigured the network but have not rebooted the host yet. Not saying that is this particular issue, but I have ran into it before.

This folder is empty

Yes, that seems to be exactly what happened. I selected DHCP during installation, but later I assigned an address to the vmbr0 interface via the config. How can I fix this now?

I selected DHCP during installation

Not possible as PVE installer wait for static ip validated or entered.

Just reboot

Just reboot

Unfortunately, this situation has been going on for a long time, reboots don't help.

Did you add proxmox to this host or did you deploy with proxmox iso?

 

[_gabriel]

if Proxmox VE ISO used, you've enabled the DHCP client manually somehow, you need to figure out where.
I had used crontab @reboot myself.

Yes, I used an ISO image for installation. Could you please tell me where to find it?

Things to try:
rgrep "d9:21:51" /etc/*
rgrep "d92151" /etc/*
rgrep "192.168.10.150" /etc/*

See if these find any instances of the MAC or IP in /etc.
You might also run those against /var as well (or separate into a few subdirs under var like lib, run, cache).

Post what you find here.

Another idea:
dhclient -r nic0
ip addr flush dev nic0
ifup nic0

nothing found in /etc or /var folders

Another idea:
dhclient -r nic0
ip addr flush dev nic0
ifup nic0

These commands were executed without errors, but the second address remained accessible
