Using your nameservers in cPanel and Plesk

To use your domain in the Internet, you need to configure nameservers. The nameservers are needed to resolve the domain names into IP addresses. We recommend to use our nameservers (ns1.contabo.net, ns2.contabo.net, ns3.contabo.net) for your domains. We provide redundant servers in different data centers and you can easily manage your DNS zones over the customer control panel. But for several reasons it can be necessary to use your own nameservers.

This tutorial provides short instructions how to manage your own nameservers with cPanel and Plesk. For most domains extensions (TLD), it is necessary to use at least two different IP addresses for two different nameservers.

In this tutorial we are going to use the domain "yourdomain.com" and want to use the nameservers "ns1.yourdomain.com" and "ns2.yourdomain.com" with the IP addresses "1.1.1.1" and "2.2.2.2".

cPanel

To use an additional IP address for a second nameserver, you will need to add the IP address in WHM at "IP Functions" - "Add a New IP Address". The DNS server will be accessible on all configured IP addresses on your server. You can use different IP addresses for the nameservers than for your website.

To use the nameservers with your domains, you will need to add them in WHM at "Server Configuration" - "Basic Webhost Manager® Setup". At the end of the page you can enter the nameserver you would like to use. After you entered the nameserver, you need to select "Configure Address Records". Please enter the IP address you want to use for this nameserver and press "Configure Address Record". After this is finished you can close the windows using "Close". Please note, that in some conditions -- for example if the nameservers are currently configured on a different server -- the entries for the nameserver will not be updated immediately. After you have finished, please press "Save changes".

Now you can "Create a New Account" with your domain at WHM - "Account functions". The configured nameserver will be used in the configuration of your new account and the DNS zone will be created with default values. You can see all DNS entries at WHM - "Edit DNS Zone".

On this page you can manage all DNS entries of your domain. Most entries are for internal usage and should not be changed. To manage user defined values, we recommend to use the "Zone Editor" at "Domains" in the cPanel account.

At last, you will need to configure your domain settings at your domain registrar. You need to change the nameserver entries. If you want to use subdomains of your domain, for example "ns1.yourdomain.com" for your domain "yourdomain.com", you will need to configure so called "Glue Records". This means, the domain registrar does not only save the name of your nameservers, but also the IP address. In some cases it is required to configure the new IP addresses for the nameservers at the current DNS zone of your domain.

After you have finished the configuration, it can take up to 24 hours until the new settings are propagated correctly. To test your nameservers and the name resolution for your domain, you can use tools like intoDNS. This tool will test the settings at your DNS provider and of your nameservers.

Plesk

At first you will need to create your domain in Plesk. At "Websites & Domains" you can see an overview of your domains.

To use a second IP address for your nameservers, the IP address needs to be configured at "Tools & Settings" - "Tools & Resources" - "IP Addresses". The DNS server responds to all configured IPv4 and IPv6 addresses. You can use different IP addresses for your nameservers than for your websites.

All DNS zones in Plesk will be configured based on a DNS template. You can find the settings at "Tools & Settings" - "General Settings" - "DNS Template". In the DNS template you can configure all entries you need for all domains on your server. Beside some default entries and entries for internal services like webmail, the settings for the nameservers can be found here. By default Plesk creates two nameserver entries "ns1.yourdomain.com" and "ns2.yourdomain.com", but with the IP address of your domain. If you want to use the same nameservers for all your domains, we recommend to change the NS entries and the IP addresses of your nameservers in the template. If you want to use different nameservers, you can also change these settings later in the DNS zone of your domain. After you have finished the configuration of the DNS template, you will need to apply the DNS template to all domains.

Now you can see the new settings also in the DNS zone of your domain. You can manage the DNS zone at "Websites & Domains" - "yourdomain.com" - "DNS Settings". There you can add, edit and delete DNS entries.

At last, you will need to configure your domain settings at your domain registrar. You need to change the nameserver entries. If you want to use subdomains of your domain, for example "ns1.yourdomain.com" for your domain "yourdomain.com" as your nameservers, you will need to configure so called "Glue Records". This means, the domain registrar does not only save the name of your nameservers, but also the IP address. In some cases it is required to configure the new IP addresses at your current DNS zone of your domain.

After you have finished the configuration, it can take up to 24 hours until the new settings are propagated correctly. To test your nameservers and the name resolution for your domain, you can use tools like intoDNS. This tool will test the settings at your DNS provider and your nameservers.

DomainKeys and DKIM in Plesk and cPanel

DomainKeys and DKIM can help you to increase the reputation of your e-mail server and preventing others to manipulate or fake your e-mails. In this tutorial, we want to show you how you can activate this feature in cPanel and Plesk. Firstly, we have to clarify that Plesk allows you to activate DomainKeys in the web interface and that cPanel is using the newer version called DKIM. Those are both quite similar in many points, but we will use those terms separately. All the images in this tutorial can be shown in a bigger version with all the details, by clicking on them. We will often use the example domain "yourdomain.com". It has to replaced with your own one, whenever it appears.

DKIM in cPanel

After you logged into your cPanel account, please search for "Authentication" in the search bar. The matching tool will now get shown in the e-mail section. After opening it, you might see that DKIM has not been activated so far. In this case, please click on the button "Activate". The notification should now look like this, possibly with an error message:

new

If you have your own server with cPanel and you are using it as a name serrver, the configuration of DKIM might be finished already. In this case, the notification will look like in this picture.

If there is, as already mentioned, an error shown, you will have to translate the raw DKIM record into the final record with the correct syntax and insert it into your DNS zone manually. So please mark and copy the whole raw DKIM record. cPanel offers the code in a form we cannot use directly.  Before we can use it, we have to remove all wrong special characters. For this purpose, we can use Notepad, which is available in every basic Windows installation.

 Please insert the string into the editor:

editor raw

The following has to be removed: everything that stands before "v=DKIM1".  Also all the double quotation marks before,  in the middle or at the end of the key. Furthermore, we have to delete the \ in front of the last ";". Please check that there are no line breaks. Now we have to analyse the part after: "p=". In this part, all whitespaces have to be removed. If you had to remove a " in the middle of the key, there will be such a white space right afterwards. If there are none of the mentioned special characters, it is absolutely okay. The result should look like this:

DKIM fin

Now you have to create a TXT record on your DNS server in the DNS zone for the subdomain "default._domainkey.yourdomain.com". The character string created in the previous step, beginning with: "v=DKIM1...", has to be put into the data part of the record. "your domain.com" has to be replaced with your own domain. If you are using our Contabo nameservers for your domain, please log into the Customer Control Panel, navigate to: DNS Zone Management and edit your domain. Please fill in the fields below "create a new entry" like in the following example:

newnew

When you now reload the tool "Authentication" in cPanel with the key F5 on your keyboard, the following should be shown:

success

If you can see the same message, DKIM has been activated successfully.

If there is still an error shown, you should recheck all the points so far. Are you using the nameservers from Contabo or different ones? Did you change the raw DKIM record correctly?  If you have any questions, you can ask our support. We are reachable over the e-mail address support@contabo.com. It would be a pleasure to help you in this matter

Add-on Domain in cPanel

cPanel uses a new key pair for add-on domains. Therefore you can not use the DKIM record from your main domain for the add-on domains too. You have to extract it from the DNS zone management in WHM first, if you are not using your cPanel as DNS server. Webspace customers do not have access to the administrative WHM panel. So please just ask us for the required key. Customers with their own server have to log into WHM.  There, please open the option "Edit DNS Zone" and choose your domain from the list. You should now see several records of different types. You need the one with the name: "default._domainkey". It should be there, if DKIM authentication got activated in cPanel previously. The needed key is added as TXT record on the right side. Please edit it as explained in the chapter "DKIM in cPanel". Finally, please add it in the DNS zone Management of your really used nameserver, for example the Contabo Customer Control Panel.

DomainKeys in Plesk

Please search in the search bar for: "Mail Server settings" and open the tool. At the point : "DomainKeys spam protection", please check the Box "Allow signing outgoing mail". Afterwards, you have to change to the "Mail Settings" of your domain and activate "Use DomainKeys spam protection system to sign outgoing email messages " there, like in the following screenshot:

newnewnew

Then you can open the "DNS Settings" for the affected Domain. An additional TXT entry for the subdomain: "default._domainkey.yourdomain.com" should have appeared.

neeeeew

If it is missing, please repeat all the steps so far, but firstly delete the tick at "Allow signing outgoing mail" in the Mail Server Settings and set it again after saving. If you are using your Plesk as nameserver, the configuration should be finished now. You should now test the configuration. More about this step in the later point: How to test DomainKeys and DKIM.

If you are using other nameservers for your domain, for example the ones provided by Contabo, you have to copy the data part completely and add an identical record in the zone there. To do so, please log into the Customer Control Panel of Contabo, go to the DNS Zone Management and edit the Domain. Please add, like in the following example, a TXT record for the subdomain "default._domainkey.yourdomain.com" with the data part generated by Plesk.

finnew

As you can see in the picture, a second record has to be added. This one defines the policy, that every e-mail has to have a DomainKeys signature. Please add the subdomain "_domainkes.yourdomain.com" with the TXT record: "o=-". With this last step, the configuration of DomainKeys has been finished. To ensure that everything is working perfectly, you should do a test now!

 How to test DomainKeys and DKIM

A good way to test a DKIM or DomainKey configuration, is the DKIMValidator.

After opening the site, you can see a randomly generated e-mail address. Please write an e-mail from your server to this address and, after a few seconds of waiting, open the analysis report with the button "view results". With Strg + F, you can search the site, which gives you a lot information. To check if DomainKeys and DKIM are working, search for: "result =". If it reads "pass", everything is working fine. If there is a "fail" you should start a search for the cause. If you are stuck at some point, you can contact us anytime under the e-mail address support@contabo.com. Our team of experts will stand by your side to get it working!

Integration of the WebDAV feature of Webspace packages

With WebDAV, cPanel supports a helpful function to provision your data over a web service. It works similar to a cloud based data storage and this functionality is also integrated into our Webspace packages. To utilize this feature you will have to log into your cPanel and click on the 'Web Disk' button under the 'Files' section.

If you are unable to find it, we recommend to use the search box and enter 'Web Disk'.

WebDAV1ENG

You will be redirected to the Web Disk main account after clicking on the Web Disk button. This root-account is preconfigured and can be used right away. Username and password are the same as your cPanel login credentials for this account.

WebDAV2ENG

As seen in the following picture, you can create additional Web Disk accounts with custom logins. The default directory is '/', but for additional accounts we recommend to create extra folders for non-root users. You are able to set read/write permissions for the accounts just as you wanted.

WebDAV3ENG

Important note: If you are using a Windows operating system on your home computer and you do not want to use encryption, you will have to activate the Digest-Authentification to establish a connection on port 2077 without encryption. Our server also provides a signed SSL certificate to ensure a secure encrypted connection between your home computer and your Webspace package on port 2078, in this case no activation of the Digest-Authentification method is required.

To proceed click on 'Actions' for the corresponding account and in the following on 'Activate Web Disk'.

You will be redirected to a new screen and prompted to choose the operating system of your home computer, as seen in the following picture.

WebDAV4ENG

Example: If you have Windows® 8 installed, please choose 'Microsoft®-OS' and click on Windows® 8.

WebDAV5ENG

On the same screen, please click on the following button in your cPanel user interface to download the quick start script.

WebDAV6ENG

Run the downloaded script and log-in using your configured Web Disk account credentials at the login prompt.

WebDAV7ENG

A shortcut will be created automatically by the script on your desktop for your Web Disk access. As seen in the following picture, the connection is successfully established if you click the shortcut.

WebDAV8ENG

You are now able to move data between your home computer and your Web Disk space via drag and drop.

Example: test.txt

WebDAV9ENG

You can also see the copied data by logging into your cPanel and clicking on file management. You may browse to the corresponding folder to check if the copied files are there.

WebDAV10ENG

You are now able to copy data between your home computer and your Web Disk space.

Concluding Information: The transfer speed is dependant on your internet connection speed at home. The connection is established in encrypted mode between your local computer and our server.

Configuring additional IP addresses

Upon ordering a Dedicated Server or VPS you will receive one IPv4 address and one /64 IPv6 subnet. As an example, this could be the IPv4 address 192.51.100.10 and the IPv6 subnet 2001:0db8:2a02:c200::/64.

Your server comes pre-configured with this IPv4 (192.51.100.10) and one IPv6 address (2001:0db8:2a02:c200:0000:0000:0000:0001). Additional IPv4 addresses can be ordered by contacting us at support@contabo.com or through our homepage when placing an order for a new server. These additional IPv4 address will not be added to your system automatically but will have to be configured manually.

The following will give an overview on how to configure additional IP addresses on the most popular operating systems. The server used in these examples has the primary IPv4 address 192.51.100.10 and will receive the additional IPv4 addresses 192.51.100.42 and 192.0.2.23. As a general rule we recommend configuring these addresses with a netmask of 255.255.255.255 (/32) and /64 respectively and without adding a new gateway.

CentOS 6.x

CentOS has all its network interface configuration files stored in /etc/sysconfig/network-scripts/. In order to configure additional IPv4 addresses, one virtual interface per additional IPv4 address has to be created. If the main interface is e.g. eth0, the virtual interfaces would be named eth0:0, eth0:1, eth0:2 and so on. Their configurations reside in individual configuration files named ifcfg-eth0:0, ifcfg-eth0:1, ifcfg-eth0:2 receptively.

#/etc/sysconfig/network-scripts/ifcfg-eth0:0
DEVICE=eth0:0
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.51.100.42
NETMASK=255.255.255.255

#/etc/sysconfig/network-scripts/ifcfg-eth0:1
DEVICE=eth0:1
BOOTPROTO=none
ONBOOT=yes
IPADDR=192.0.2.23
NETMASK=255.255.255.255

Additional IPv6 addresses can be specified using the variable IPV6ADDR_SECONDARIES in the interface's primary configuration file (/etc/sysconfig/network-scripts/ifcfg-eth0 in case of eth0). Multiple addresses are separated by a white space:

#/etc/sysconfig/network-scripts/ifcfg-eth0
...
IPV6ADDR_SECONDARIES=2001:0db8:2a02:c200:0000:0000:0000:0002/64 2001:0db8:2a02:c200:0000:0000:0000:0003/64
...

To apply the changes, restart the network service:

service network restart

CentOS 7.x / Fedora

The network interface configuration files of both CentOS 7.x and Fedora are stored under /etc/sysconfig/network-scripts/. Additional IPv4 addresses can be added to the respective interface's configuration file by using variables of the pattern IPADDR0, IPADDR1, IPADDR2 and PREFIX0, PREFIX1, PREFIX2 etc., in case of e.g. eth0 this would be /etc/sysconfig/network-scripts/ifcfg-eth0:

#/etc/sysconfig/network-scripts/ifcfg-eth0
...
IPADDR0=192.51.100.42
PREFIX0=32
IPADDR1=192.0.2.23
PREFIX1=32
...

The old method using virtual interfaces as employed in CentOS 6.x and described above will also still work.

Additional IPv6 addresses can be specified using the variable IPV6ADDR_SECONDARIES in the interface's primary configuration file (/etc/sysconfig/network-scripts/ifcfg-eth0 in case of eth0). Multiple addresses are separated by a white space:

#/etc/sysconfig/network-scripts/ifcfg-eth0
...
IPV6ADDR_SECONDARIES=2001:0db8:2a02:c200:0000:0000:0000:0002/64 2001:0db8:2a02:c200:0000:0000:0000:0003/64
...

To apply the changes, restart the network service:

service network restart

cPanel

With cPanel there is no need to deal with configuration files. Log in to WHM and navigate to "IP Functions" » "Add a New IP Address". Enter the IP address, select subnet mask 255.255.255.255 and click "Submit":

cpanel-ip

Debian / Ubuntu

Debian's and Ubuntu's network interface configuration is stored in /etc/network/interfaces. Additional IP addresses can be assigned by adding them in separate iface192.51.100.42 and 192.0.2.23 to eth0 whose primary address is 192.51.100.10:

#/etc/network/interfaces
auto eth0
allow-hotplug eth0
iface eth0 inet static
address 192.51.100.10
netmask 255.255.255.255
gateway 192.51.100.1

iface eth0 inet static
address 192.51.100.42
netmask 255.255.255.255

iface eth0 inet static
address 192.0.2.23
netmask 255.255.255.255
...

Additional IPv6 addresses are configured similarly:

#/etc/network/interfaces
...
iface eth0 inet6 static
address 2001:0db8:2a02:c200:0123:4567:89ab:0001
netmask 112
gateway fe80::1
accept_ra 0
autoconf 0
privext 0


iface eth0 inet6 static
address 2001:0db8:2a02:c200:0000:0000:0000:0002
netmask 64
...

To apply the changes, restart the networking service:

service networking restart

Or:

ifdown eth0; ifup eth0

openSUSE

openSUSE has its network interface configuration files stored under /etc/sysconfig/network/. All settings concerning e.g. eth0 are saved in ifcfg-eth0, additional IPv4 and IPv6 addresses can be added using the pattern IPADDR_1, IPADDR_2, IPADDR_3 etc:

#/etc/sysconfig/network/ifcfg-eth0
...
IPADDR_1='192.51.100.42/32'
IPADDR_2='192.0.2.23/32'
IPADDR_3='2001:0db8:2a02:c200:0000:0000:0000:0002/64'
IPADDR_4='2001:0db8:2a02:c200:0000:0000:0000:0003/64'
...

To apply the changes, restart the network service:

service network restart

Windows Server 2008, 2012 and 2016

Open the "Network and Sharing Center" and click on "Local Area Connection".

In Windows Server 2016:  Open the "Network and Sharing Center" and click on "Ethernet".

ws2008_01

In the newly opened windows, click on "Properties".

ws2008_02

If you want to add an additional IPv4 address, select "Internet Protocol Version 4 (TCP/IPv4)" and click on "Properties".

ws2008_03

In the newly created windows, click on "Advanced..." and in the following one on "Add..." under "IP addresses"

ws2008_05

Enter the new IP address and its netmask into the dialog and then click "Add".

ws2008_06

The new IP address is now active.

ws2008_07

IPv6 addresses can be added similarly by selecting "Internet Protocol Version 6 (TCP/IPv6)":

ws2008_08

ws2008_09

ws2008_12

cPanel/WHM: Best practices

Our Dedicated Servers and VPS's with cPanel are very popular among our customers. The easy to use administration panel renders web hosting comfortably even for inexperienced Linux administrators. Almost all settings can be done via WHM, SSH access is rarely necessary.

We deploy cPanel servers automatically with a working standard configuration. Most settings are left default, some had to be added to make the server accessible. I want to show you a few points that are important after the installation.

The following steps can be done in your server WHM. Please log in to https://[server-IP]:2087 as root to continue.

Even if you have not worked with the WHM interface yet, you will be able to navigate through it easily. I find the search bar very useful to access the needed function quickly. It acts similar to the Windows 7 start menu search.

cPanel Search

  1. We start with Basic cPanel & WHM Setup.
    1. Notice the contact e-mail address in the first configuration line. We recommend changing it to a personal address to keep yourself informed about server activities. cPanel is quite active in this regard, so a separate in-box is advisable.
    2. You will find the default nameservers at the bottom of the page. We have predefined our nameservers here. Domains that you bought from us will work out of the box using this setting. If you run domains on other nameservers, you can define their addresses here.
  2. We continue with Configure Remote Service IPs. Choose the tab Remote Name Server IPs here. The following list of IP addresses are associated to the nameservers defined before. If you only use domains from us, no changes are necessary here. If you have domains on other nameservers, you can add their IPs to the list. Otherwise cPanel will refuse to add those domains as addon domains.
  3. The next point is Change Hostname. Our predefined hostname does not resolve to your server IP by default. You will have to define a new one with a working domain to avoid problems with e-mail transmission. You may leave the first section as it is, e.g. "vmi1234.example.com". If you use a domain that is not hosted on our nameservers, make sure to add an A entry for the sub-domain in your DNS management.
  4. A correct RDNS entry is another important factor for RFC compliant e-mail transmission. The PTR of an IP must match the server hostname. Please use our Customer Control Panel to set the entry for your server IP, e.g. "vmi1234.example.com".
    Update 19 December 2014: We now set a default host name in the contabo.host zone which resolves correctly. There are no adjustments necessary in this regard anymore.

After these steps, your cPanel server is ready to fulfil all general hosting tasks. If you need more help material, please see the comprehensive cPanel documentation.
