Replace Motherboard

[voodooutt]

I changed the motherboard from the "original" one that proxmox was installed on. The Ethernet port is not working now, and who knows what else. How to update so proxmox can initialize the new mobo/ethernet port?

What output do you get from: ip l (l means letter l)
And also what output does cat /etc/network/interfaces show

Probably the name of the ethernet device changed.

Like others already posted, the interface name probably changed.

List all interfaces with their settings via "ip a"

Make sure the right interface is configured under /etc/network/interfaces

Please post the output of "ip a" and "cat /etc/network/interfaces"

Thanks for the help

output of "ip l"
output of "ip a"
output of " cat /etc/network/interfaces"

Your new motherboard only has 1 nic available.

To fix your situation remove the line "iface enp2s0 inet manual"
And replace "bridge-ports enp2s0" with "bridge-ports enp1s0"

Your network interfaces should look like this afterwards:

auto lo
iface lo inet loopback

iface enp1s0 inet manual

auto vmbr0
iface vmbr0 inet static
    address 192.168.1.111/24
    gateway 192.168.1.1
    bridge-ports enp1s0
    bridge-stp off
    bridge-fd 0

reboot the host and you should be able to ping it

to make sure all other mainboard features are working check the output of "dmesg -T" for any red warnings / errors, only in really rare cases you might have to set custom kernel options to get features working

changing the interfaces did the trick! Can access now.

Also, the output of dmesg -T scrolls too fast. How to show line-by-line?

pipe to less, and then scroll trough with arrow keys or page scroll down/up.

But you are most likely fine, most messages might confuse you.

dmesg -T | less

all looked good. Thanks for the help. I figured it was something simple, just did not know the commands to do so.

what code to type to remove the line and change the bridge port?

also, what should i do in this situation? (attached)

type "nano /etc/network/interfaces" to edit the file

then replace "enp4s0" with "enp3s0" ( 2 times in total )

hit ctrl+x to exit, type "y" to save and hit enter

cat the file again to make sure the changes got applied.

then "reboot"

this is simple for you but it was a lifesaver for me. you save my lots of time.
Giving thanks is too little.
