Last post by Suhitha - Sep 27, 2025, 05:55 AM
Question: How to Create a VPC 2.0 Network

A process that prepares and configures a server or service for use after initial deployment.

A Virtual Private Cloud (VPC) 2.0 network creates a secure, enhanced, and isolated private networking environment for instances to connect and share resources. VPC 2.0 networks support IPv4 network addresses to enable communication between instances.

Follow this guide to create a Virtual Private Network (VPC) 2.0 network using the Vultr Customer Portal, API, CLI, or Terraform.


Vultr Customer Portal

1.Navigate to Products, expand the Network drop-down and select VPC 2.0 from the list of options.

2.Click Add VPC 2.0 Network to set up a new VPC.

3.Select your target Vultr location to create the VPC network.

4.Click Configure IPv4 Range to enter a custom private IPv4 subnet to assign the network, or keep Auto-Assign IP Range selected.

5.Enter a new label in the VPC 2.0 Network Description field to identify the network.

6.Click Add Network to create the new VPC network and verify that it's available in your Vultr account.

Last post by senthil - Sep 27, 2025, 05:54 AM
Applicable to:
  • Plesk for Linux
  • Plesk for Windows
Question
  • Does Plesk provide Encryption at Rest?
Answer
Plesk is not equipped with encryption software that provides at-rest encryption capabilities.

However, most cloud service providers already do provide it on the hard disk level, either by default or with some configuration:

  • Azure Encryption at Rest
  • Google Cloud Encryption
  • AWS Encryption of Data at Rest

Our recommendation is to consult your service provider for further information on that.

Additionally, there is a suggestion for this feature in Uservoice:

Question: How to Attach a VPC 2.0 Network to a Vultr Instance


A feature that allows you to connect additional resources like block storage volumes to your Vultr instances for expanded capabilities.

Attaching a VPC 2.0 network to an instance enables a new private networking interface that supports communication with other nodes on the same network. You can attach multiple VPC 2.0 networks to an instance to enable connections with other hosts on each subnet.

Follow this guide to attach a VPC 2.0 network to a Vultr instance using the Vultr API, CLI, or Terraform.


Vultr API

1.Send a GET request to the List VPC 2.0 networks endpoint and note the target VPC 2.0 network's ID in your output.

Code Select
console


$ curl "https://api.vultr.com/v2/vpc2" \
    -X GET \
    -H "Authorization: Bearer ${VULTR_API_KEY}"


2.Send a GET request to the List Instances endpoint and note the target instance's ID.

Code Select
console


$ curl "https://api.vultr.com/v2/instances" \
  -X GET \
  -H "Authorization: Bearer ${VULTR_API_KEY}"

3.Send a POST request to the Attach nodes to a VPC 2.0 network endpoint to attach the instance to the VPC 2.0 network.

Code Select
console


$ curl "https://api.vultr.com/v2/vpc2/{vpc-id}/nodes/attach" \
    -X POST \
    -H "Authorization: Bearer ${VULTR_API_KEY}" \
    -H "Content-Type: application/json" \
    --data '{
        "nodes": [
            "<instance-id>"
        ]
    }'


Vultr CLI

1.View the list of VPC 2.0 networks in your Vultr account and note the target network's ID.

Code Select
console


$ vultr-cli vpc2 list

2.View the all instances and note your target instance's ID.

Code Select
console


$ vultr-cli instance list

3.Attach the VPC 2.0 network to the instance.

Code Select
console


$ vultr-cli vpc2 nodes attach <vpc2 id> \
    --nodes="<instance id>"

Terraform

1.Open your Terraform configuration for the existing instance.

2.Add the VPC 2.0 network ID to the instance vpc2_ids list, then apply.

Code Select
terraform


resource "vultr_instance" "server" {
    # ...existing fields (region, plan, os_id, label)
    vpc2_ids = [var.vpc2_id]
}

3.Apply the configuration and observe the following output:

Apply complete! Resources: 0 added, 1 changed, 0 destroyed.

Last post by senthil - Sep 27, 2025, 04:01 AM
Question
After updating Plesk to 18.0.69 with MariaDB 10.11 and higher, the "root" user is added to MySQL users. Why
is it needed?
Answer
The behavior change was introduced in Plesk 18.0.69
Specifically due to:

  • Updating MariaDB to version 10.11 in Plesk on AlmaLinux no longer causes issues with log rotation.
    (PPPM-14895)

The reason behind this is to address an issue with the MariaDB logrotate post-rotation script from the
configuration files provided by MariaDB.

Last post by senthil - Sep 27, 2025, 03:57 AM
Question
  • How to configure rate limiting for login attempts in Plesk?
Answer
Starting with Plesk Obsidian 18.0.70, Plesk supports rate limiting for login attempts. This feature is enabled by
default on all installations, and can be additionally customized via Panel.ini Editor extension with the following
options in the [security] section:

  • Option "bruteforceProtection.enabled". This option defines whether brute force protection is enabled or not.
    (Default value true)
  • Option "bruteforceProtection.rateLimit". This option defines the number of failed login attempts per IP
    address.(Default value 5)
  • Option "bruteforceProtection.rateLimitPeriod". This option defines the period in seconds for catching the
    failed attempts.(Default value 300)

Example:

Code Select
[security]
bruteforceProtection.enabled = true
bruteforceProtection.rateLimit = 5
bruteforceProtection.rateLimitPeriod = 300Based on these settings, if the client has five failed login attempts, the next attempts will not be
processed for 300 seconds starting with the first failed attempt.
