[SOLVED] Proxmox change IP address

[sandtech]

Hi,

I recently attempted to change the IP address of my Proxmox server (192.168.3.12---> 192.168.10.54) and updated it in the /etc/network/interfaces file but to no success. Surprisingly, reverting to the old IP (192.168.3.12) while connected to the (192.168.10.XX) network resolved the issue.

Any insights into what might be causing this?

Hey,

you have to update both, /etc/network/interfaces and /etc/hosts.

For other people who might find this thread, this applies only for single hosts. Once you have your host as part of a cluster, it gets more complicated: Corosync and maybe Ceph if you use it.

I tried, but to no luck. I even live booted Kali Linux on the server to check if I actually had internet connection (which I did)

You might also need to change your DNS accordingly by editing the /etc/resolv.conf in case you previously pointed it at your router and not at a public DNS server.

THANKS THAT WORKED!
