Getting Started with OpenPanel After Deployment

After payment for the order received on the email address registered during registration, you will receive a notification about the server's readiness to work. This notification will include the VPS IP address as well as login and password credentials for connection. Our company's clients manage their servers through the servers control panel and APIInvapi.

After clicking on the webpanel link, you will be directed to an authentication window. Here, please use the credentials provided in the Info >> Tags tab. The login is root, and the password is specified in the :fontawesome--solid-tags: opencli_root tag.

The authentication data can be found either in the Info >> Tags tab of the server management panel or in the email sent:

  • Link for accessing OpenPanel web interface: in the webpanel tag. The exact link, in the format https://<Server_ID_from_Invapi>, is sent via email upon server delivery;
  • Login: root;
  • Password: in the :fontawesome- solid-tags: opencli_root tag.

After clicking on the link, you will need to authenticate in OpenAdmin:

The startup menu of OpenAdmin contains the following categories:

  • Dashboard: The main page of the control panel, providing an overview of the system, including user accounts, installed packages, resource usage, and operational notifications.
  • Users: A section for managing user accounts. Here, you can create, edit, or delete accounts, assign hosting plans, set resource limits, manage domains and databases, and more.
  • Plans: Allows you to configure and manage hosting plans that define limits and resources for user accounts, such as disk space, traffic, database quantity, and other parameters.
  • Backups: A tool for creating backups of user accounts, websites, databases, and the entire system. You can also restore from backups and schedule automatic backups here.
  • General Settings: Global settings for the control panel, including language preferences, email settings, firewall configurations, DNS settings, FTP settings, and other global configurations.
  • Docker: A section for managing Docker containers, allowing you to create, start, stop, or delete containers on your server.
  • OpenPanel: Settings and information related to the OpenPanel itself, including updates, licenses, security parameters, and event logs.
  • Firewall: Management of your server's firewall, setting rules for the network, blocking or allowing IP addresses, and more.
  • ModSecurity: Configuration and monitoring of ModSecurity, a web application module designed to enhance security against attacks.
  • OpenAdmin: The OpenAdmin utility for managing your Linux system at a lower level, allowing you to control services, processes, file systems, and other system components.

Setting up a New Web Hosting with OpenAdmin

On the startup page of the OpenPanel web interface, you will find an interface for setting up a new hosting plan:

The process of setting up consists of several steps:

  • Set custom domain instead of IP address: Instead of using a numerical IP address that is difficult to remember, this step allows you to assign a user-friendly and memorable domain name to your website or server. By default, it is set to <Server_ID_from_Invapi>;
  • Set at least 2 nameservers: This step assumes setting up at least two name servers (DNS servers) for ensuring fault tolerance. Name servers respond to domain name resolution and IP address mapping;
  • Create new Plan and create User account: Here, you need to create a new hosting plan that defines limits and resources for the user account (disk space, traffic, databases, etc.). After that, you must create a user account and assign it this plan;
  • Install & Enable ModSecurity WAF for domains: ModSecurity is a web application firewall (WAF) designed to protect websites from various attacks such as cross-site scripting (XSS), SQL injections, and other vulnerabilities. This step assumes installing and activating ModSecurity for ensuring the security of hosted domains;
  • Schedule remote Backups: On this step, you need to set up regular creation of backup copies of user accounts, websites, and databases on a remote storage for enhancing reliability and data restoration in case of failures.


Detailed information about the main OpenPanel settings can be found in the developer documentation.

Opening SMTP Ports for Corporate Email Service

To ensure security and prevent spamming, outgoing TCP ports (25, 24, 2525, 387, 465, and 587) and UDP port (5060) are blocked by default on all VPS servers. To unblock these ports, follow these steps:

  1. Register your domain zone. An A-record for the domain must point to the IP address of your server at HOSTKEY.

  2. Submit a request to our technical support, specifying that you need to open outgoing SMTP ports for sending email and providing the domain (or subdomain) from which it will be sent.


    We reserve the right to ask additional questions about your domain name and its usage scenarios.

  3. After analyzing your domain name, we will make a decision on opening the ports for SMTP operation and notify you.
