Time & Date

Default Timezone

The default timezone is stored in newly created user accounts.

Default Datetime Format

The default datetime format is stored in newly created user accounts. It defines how the user interface shows the datetime format (e.g. hh🇲🇲ss).

UI Settings

Precheck redirect checkbox on add server

Precheck the "redirect to server page" checkbox when adding a new user.

Precheck redirect checkbox on add user

Precheck the "redirect to user page" checkbox when adding a new user.

Precheck delete VPS on backend checkbox

Precheck the "Delete on Hostsystem" checkbox when deleting a virtual server.

Network graphs: Display summary by default

By default, the extended statistics that include a summary of the selected time range for 95th percentile, average mbit, transfer volume, and current data rate are hidden. You can display this information by clicking the "Show Summary" button.

To expand the statistics by default, activate this option.

Network graphs: Display 95th percentile line

To display a 95th line in the network graphs, activate this option.

Don't allow duplicate external provider assignments

Enable this option to ensure that external provider assignments are unique. This allows identical item ID assignments only if they are managed by a different external provider account.

For instance, this option ensures that the same Proxmox server cannot be assigned multiple times. However, if you manage two Proxmox accounts with servers that have the same ID, servers with the same IDs can still be assigned since they are managed by different external provider accounts.

Don't allow duplicate IPMI IPs

Enable this option to ensure that each server has a unique IPMI IP address. This allows duplicate IPMI IPs only if they are managed by different agents.

Don't allow duplicate DHCP MACs

Enable this option to ensure DHCP MACs are unique per agent. This allows duplicate MACs only if they are managed by different agents.

Open dialog during requesting server console

The server console is opened in a new tab, which could be blocked by popup blockers. By enabling this option, an additional dialog (modal) opens when a console is requested, which contains a direct link to the console.

Connection assignments: Don't show already assigned items

Enable if already assigned items (e.g. a switch port) should not be available in the item-selection dropdown of other servers.

Admins: Allow power actions during PXE boots

This feature enables the execution of power actions by admins through the 'Power Options' button while a PXE boot is in progress.

Users: Allow power actions during PXE boots

This feature enables the execution of power actions by regular users through the 'Power Options' button while a PXE boot is in progress.

This option is not recommended for regular users, as they could potentially restart the server during installation, thereby putting the successful completion of the PXE boot at risk.

Censor IPMI passwords

Three modes are available for selection:

  • Show IPMI passwords in clear-text.
  • Hide IPMI passwords and censor them in API responses.
  • Mask IPMI passwords with an option to reveal.

RDNS Automation

Delete RDNS entry when removing IP assignment

Deletes the RDNS entry when you remove an IP assignment from a server. Using the next option, you can replace the entry with a default value.

Set default RDNS entry after removing IP assignment

This feature lets you reset the RDNS entry to a default value. Besides static text, you can use the following variables:

  • {reverseip} - IP will become
  • {reverseipNoArpa} - IP will become
  • {ip} - Replaces {ip} with the IP address. E.g. {ip} becomes
  • Leave the input field empty to remove the RDNS entry.

You can combinate multiple variables, and you can use the same variable multiple times (e.g. {ip}-{reverseip}

RDNS entry verification mode

Verification mode when the RDNS entry is being updated. Possible values:

  • Valid domain, but must not resolve to IP.
  • Valid domain and must resolve to IP.
  • Allow all strings.

System Settings

IPMI-KVM NoVNC Docker container deletion mode

Available options:

  • Delete unused containers after 5 minutes (Default)
  • Delete unused containers as fast as possible

Docker containers are terminated when they are no longer in use. The default setting is to delete them after around 5 minutes. Some IPMI vendors may only allow one KVM connection at a time, leading to new sessions only being available after previous sessions have ended. The main benefit of the default mode is that the same NoVNC window can be re-opened for up to 5 minutes.

Alternatively, a quick deletion mode is available, where containers are removed within seconds after the user disconnects. This is useful to solve the above described issue, but it also means that the same NoVNC window can only be re-opened for a short time (which is generally not a problem).

IPMI-KVM NoVNC: Disable IP verification

If enabled, anyone knowing the unique URL token can access console sessions from any IP. For security reasons, it is highly recommended to leave this option disabled.

Hardware inventory callback IP validation

When activated, this feature verifies the IP address of the server during the retrieval of hardware details through the hardware inventory shell script. This ensures that data callbacks are only accepted if they originate from an IP address linked to the server. This verification step prevents the acceptance of hardware details from a server whose IP does not match those on record in Tenantos, thereby eliminating the risk of storing incorrect hardware data.

In other words: If you accidentally run the hardware inventory shell script on the wrong server, the system will prevent the storage of hardware details. This is because the origin IP address won't match with the server's IP assignments in Tenantos.
