Proxmox Configuration After Installation

Contents

Objective

Provide a guideline on essential basic Proxmox configurations after successful installation.

On WinSCP, connect tot the Proxmox server.

Then, run this command to move to the following directory.

cd /var/lib/vz/template/iso

Afterwards, transfer the ISO file from local to the remote site.

Remove the existing Proxmox logo with the following command.

rm /usr/share/pve-manager/images/proxmox_logo.png

Then, change your current directory to /images/ using the following command.

cd /usr/share/pve-manager/images/

After that, download your company logo with the following command.

wget http://www.netonboard.com/download/proxmox_logo.png

Backup the existing pvemanagerlib.js file using the following command.

cp /usr/share/pve-manager/js/pvemanagerlib.js /usr/share/pve-manager/pvemanagerlib.js_BKP

Then, edit the pvemanager.js file with nano.

nano /usr/share/pve-manager/js/pvemanagerlib.js

After you have opened the file, search for the line that writes

if (data.status !== 'Active') {

After you have found that line, change it to the following:

if (false) {

On Proxmox, make sure to enable firewall on Datacenter, cloud, and the selected VM.

Then, on your selected VM, under the Firewall option, select and create a new IPSet (e.g. ipfilter-net0).

Next, click on your newly-created IPSet and select Add to make a new IP/CIDR (this specifies what IP can access) – Use your VM’s IP address

Navigate to Firewall > Options and enable IP filter.

Afterwards, navigate to Hardware and click on Network Device. Select Edit and tick the Firewall option.

For testing, replace your VM’s IP with a static IP via nmtui and do a ping test.

Any other IP addresses than the specified IP/CIDR would not be able to ping external sites.
