How To Unblock Your IP Address in Manage

Liquid Web has introduced a new feature designed to simplify the removal of errant IP address blocks in the firewall, and allow customers to quickly remove their own address from within their Manage dashboard. In this manner, customers can remove blocks on their IP addresses even when they are unable to access WebHost Manager itself due to the block.

Pre-Flight Check

  • The cPanel Quick IP Address Unblock feature is designed for servers using the ConfigServer Firewall (CSF).
  • The feature does not apply to any server utilizing a different firewall.
  • You must have access to your Manage dashboard to use the IP delist feature.
    Note: Customers with Dedicated, Storm, or VPS servers which are not currently using the CSF firewall can request an upgrade from support to take advantage of this Manage feature. There is no charge, it typically takes only a few minutes and the only service that needs to be restarted as a result is the firewall itself. Our support technicians also can port your existing APF rules to CSF. If requesting an upgrade, please be sure to indicate whether your server uses the Guardian backup service so that its rules also can be configured.

Step #1: Log into Your Manage Interface

  1. In Manage, click on the [+] next to your server’s hostname to expand its details.
  2. Now click on the Dashboard button to open the Server Dashboard.

Step #2: Unblock the IP Address

  1. Click on the Network tab to bring up the Networking pane.
  2. You will see your current IP address, as reported by your web browser, pre-populated in the cPanel Quick IP Address Unblock field. If you wish to unblock a different IP address, simply replace the address shown in the field with the IP address you wish to unblock.
    If you’re attempting to unblock the IP address of a client, developer, or other party who does not know their public IPV4 address, you can direct them to http://ip.liquidweb.com to obtain their address for you.
  3. Click the Unblock IP button to attempt to automatically remove the IP address in the CSF firewall.

  4. The Unblock IP button will change to Working… while it attempts to delist the IP address. Once the process completes, you should see a banner indicating whether the delisting was successful.

Step #3: I Got Blocked Again. Why?

There are many reasons why an IP address can be blocked in the firewall, but the two most common are:

  • The use of an incorrect username or password combination when connecting to the server or a service such as email, ftp, ssh, or cPanel/WHM
  • A mod_security rule violation

If you are unable to determine the cause for the block, feel free to contact Heroic Support®. You also may wish to consult the following Knowledge Base articles: Unblocking an IP Address or Opening a Port in the Firewall and How to Manage the CSF Firewall in WHM/cPanel.
 
 

How To Add a DNS Record For Your Hostname in Manage

Pre-Flight Check

  • These instructions are intended for domain names using Liquid Web’s nameservers.
  • If the main domain uses other nameservers, such as at a registrar, you will need to log in there and add an “A” record for the hostname in the main domain’s DNS zone file. The record should point to the server’s primary IP address.

Whenever you create a new server (or change the name of an existing one) you will need to add (or update) the DNS record for its parent domain.

If the hostname does not resolve, you will not be able to:

  • access WHM, cPanel, or Webmail via the hostname
  • send or receive email over a secure (SSL) connection using a mail client
  • verify the authenticity of email sent by the server (which could result in mail being rejected or flagged as junk by the recipient’s server)

Fortunately, adding the record is a simple process, and you can add the record in your Manage dashboard.

  1. Once logged into your Manage interface at https://manage.liquidweb.com/manage, click on Domains in the left menu and then select the DNS tab in the Domains Dashboard.

    DNS zones

  2. Now, click the [+] next to the main domain name to expand the domain’s DNS record and click the Add New Record button at the bottom. For the host.examplesite.com server, we’ll be editing the DNS record for the main domain, examplesite.com.

    Add a DNS record in Manage

  3. Your hostname will need an “A” record pointing to the IP address of the server itself. In this case, because the server has only one IP address, it is the same as the IP address of the site.

    Add new DNS record

  4. Once you click the green checkmark button, the record will be added and DNS will begin to propagate. Typically only a few hours is needed for this, but it technically can take up to 24 hours to 48 hours for a DNS change to fully propagate globally.

 

How to Enable Two-factor Authentication (2FA)

Pre-Flight Check

  • These instructions are intended specifically for enabling two-factor authentication for Manage users.

What is Two-factor Authentication (2FA)?

Two-factor authentication (also known as 2FA) means that instead of just a password (one factor), you will need two factors (password, plus a rotating authentication token) to login to your Manage account. Only the correct combination of the first and second factors will allow you to log in. Two-factor authentication is more secure than one-factor authentication.

How to Reboot a Server via Manage

Rebooting a server in Manage has been made incredibly easy, and only takes a few clicks. Further simplifying the process, multiple servers can be rebooted at the same time!

What is a Virtual IP (VIP)?

What is a Virtual IP (VIP)?

When you create a virtual IP (VIP) address with Liquid Web you will receive both a Public VIP and Private VIP. The public VIP can be configured on a Storm server just as a non-virtual, or standard, IP would be configured. Connecting to a public service, such as HTTP or FTP, on the Public VIP occurs just as it would on a standard IP.

The Private VIP can be configured on a Storm server’s private interface just as a standard private IP would be configured. Connecting to a private service, such as MySQL or Puppet, on the Private VIP also occurs just as it would on a standard private IP.

So why use a VIP? When utilizing multiple servers, having a VIP is beneficial due to its ability to “float” between servers. This allows the VIP to remain highly reachable in circumstances in which a non-virtual (or standard) IP may be otherwise unreachable. It is possible to move both the Public VIP and Private VIP between Storm servers!

Both Public and Private VIPs can be configured on any server on your Storm account so long is that server is in the Zone where the VIPs were created. Typically software, such as the ones listed below, is used to manage on which server a VIP resides.

Use Cases for VIPs

Here are some of the things that you can do with Virtual IP addresses:

  • High Availability Databases (MySQL, Percona, MariaDB)
  • Non-DNS-based Service Migrations
  • High Availability Web Applications (in tandem with or in place of load balancer)
Examples of Software That Can Use VIPs

This is just some of the software that you can use with Virtual IP addresses:

Proactive Server Maintenance Checklist, Prior to Reboot

Take a Backup, or Be Sure Backups are Running

We have tutorials on How to Create a Storm Server Backup, and How to Restore a Storm Server Backup.

Check Running Processes

Liquid Web’s Heroic Support team closely monitors the load on your servers with Sonar® proactive monitoring and service restoration. That said, it’s always wise to glance at what processes are running on your server to assure your services are running as expected. Check-out our tutorial on Monitoring Server Processes with Top for Linux.

Verify Services Will Start at Boot

Be sure to verify that all of your necessary services are configured to start when the server boots up. For CentOS users, you can follow this tutorial: chkconfig Command Examples for Red Hat and CentOS.

Save, Save, and Save Some More

Always check whether or not there are any unsaved changes to configuration files, etc. prior to a reboot. Save early and safe often!
