Describe your issue

Hello.

Due to a hardware issue, the motherboard of my dedicated server at OVH was replaced. The server is no longer responding to pings.

After some research, it seems I need to specify the new MAC address in server the configuration.

I edited the file

/mnt/etc/udev/rules.d/70-persistent-net.rules

using nano following this model (with the correct MAC address - provided by the hosting provider - and name - found in /mnt/etc/network/interfaces
)

SUBSYSTEM==“net”, ACTION==“add”, DRIVERS==“?*”, ATTR{address}==“a8:32:E4:CD:3C:FA”, NAME=“eno1”

The server is still not responding to pings.
Could someone guide me to understand what I’m doing wrong?

Thank you in advance for your help.

Hello Linalawl,

This is a classic issue after a motherboard replacement on an OVH dedicated server. You’ve correctly identified the udev rules file, but there are likely other configuration files still referencing the old MAC address, which is why the server doesn’t respond.

OVH has an official guide covering exactly this scenario: Finalize a Maintenance Intervention on a Dedicated Server.

Hope this helps! Let us know how it goes.

Hello and thank you for the reply.

I found this page, but it’s no longer up to date.

After some research, it seems the file /mnt/etc/netplan/50-cloud-init.yaml needed to be edited (in case this is helpful to anyone).
