[SOLVED] /root/.ssh/authorized_keys overwritten

[comfreak]

Hi,

i have accidentally overwritten the file /root/.ssh/authorized_keys (more specific the file /etc/pve/priv/authorized_keys, as /root/.ssh/authorized_keys is a simlink to /etc/pve/priv/authorized_keys) in our Proxmox HA cluster. Now I can not login from the WebUI to other nodes VM consoles anymore. Everything else seems still to work.

I searched a bit around and found

pvecm updatecerts

or

pvecm updatecerts --force true

Is this the correct command to restore (generate a new) the key again? I just want to make sure not do destroy something else (the current wrong key inside the file can be deleted/overwritten...).

Thanks!

edit: more details

Solved!

I copied the public SSH key from /root/.ssh/id_rsa.pub of ervery node to the /root/.ssh/authorized_keys file. As that gets synced via the HA cluster to all nodes, I just needed to put it on one node.

if you love your cluster, /etc/pve is a path that should be included in your backup....

Good hint! Thank you!

How do you back that up?

For example, I do it like this:


7z a '-xr!lxcfs*' '-xr!defer*' '-xr!var/lib/vz/template*' /mnt/backup/proxmox.7z /etc /var /opt /root /usr
