Establishing a connection to your server via SSH

In this tutorial you will find a guide on how to establish a connection via SSH to your Linux server.

Please note that you will have to replace the place holder <IP Address> in the complete tutorial with the IP address of your server.

Linux

In case you are using a Linux operating system on your local machine you will just have to start a terminal.

To establish the connection to your server please type the following command:

The option -l defines the user which will be connected to. In this case we will use "root".
The option -p defines the port which will be used for the connection. Here we will use the standard SSH port 22.

Should this be the first time you connect to the server, you will have to accept its SSH certificate by typing "yes".

Please insert your password, which you can find in our e-mail "Your Login Data". Kindly note that SSH will not display any letters or symbols when typing the password. You can also copy and paste your password by using the right mouse key (please make sure not to copy your password with blank characters at the end - you can check so by pasting the password into an empty editor file before using it).

Now, click the ‚Enter‘-key. Once done, you should get access to your server via SSH:

The connection has now been established successfully.

Windows

In case you are using a Windows operating system on your local machine, you will have to install a suitable SSH client first.

We recommend to use PuTTy as SSH client:

http://www.putty.org/

After installing PuTTy, open the client and enter the IP address of your Server. The port, in this case the standard SSH port 22, can be changed as well if needed.

Click 'Open' to initiate the connection. You can leave all options to default.

Should this be the first time to connect to the server, you will have to accept its SSH certificate:

Afterwards, you will see the following:

Please insert root (login as:) and your password, which you can find in our e-mail "Your Login Data". Kindly note, SSH will not display any letters or symbols when typing the password. You can also copy and paste your password by using the right mouse key (please make sure not to copy your password with blank characters at the end - you can check so by pasting the password into an empty editor file before using it).

Now, click the ‚Enter‘-key. Once done, you should get access to your server via SSH:

The connection has now been established successfully.

Contabo wins German Data Center Award 2018

Last year Contabo was already honored and received the German Data Center Award 2017 for the modernization of its data center in Nuremberg. Now we took part in this year’s contest as well and faced the competition with our modernization measures that have been recently performed at our data center in Munich.

This year’s ceremony was held on April 24th 2018, and the winners of the “Deutscher Rechenzentrumspreis 2018” (German Data Center Award 2018) were honored. Again, and just like last year, an independent jury of data center experts and planners decided which of the 51 submitted data center projects would receive the award. The jury placed particular emphasis on the innovative to visionary character of the data center projects as well as on the energy efficiency which can be achieved in data center operations.

Once again, we have won the first place in category 6 – “Increase in energy efficiency through reconstruction in an existing data center” – this time with our data center located in Munich, and consequently received the German Data Center Award 2018.

This means that both of our data centers have received the German Data Center Award – a huge acknowledgement of all our modernization efforts in recent years and we are very happy about that.

In the course of the energetic optimization of our now award-winning data center in Munich all chillers which had been in use for cooling the data center were replaced by a groundwater cooling system. Now only a few pumps with a low power consumption are sufficient in order to reliably supply the entire data center with cooling – thanks to groundwater which is cool all year long.
Not only you, our valued customers benefit from this measure due to decreasing energy demand and thus rental costs for the server operation: Due to the low power consumption for the data center cooling, the environment is best protected and the groundwater flows back to the soil unchanged.
All this work was carried out without any interruption of the operation of your servers, thanks to extensive planning and project scheduling as well as precautionary activities. We have thousands of servers online in our data center in Munich, and all these actions were performed noiseless.

 

The PUE value (PUE = “Power Usage Effectiveness”) of our data center in Munich could be reduced from 1.4 to less than 1.1 and at the same time, the cooling power was increased. Power capacity which was up to now reserved for peak loads of the chillers in midsummer could be used to accommodate hundreds of new servers in the data center. The electricity requirement for cooling the entire data center is thus negligible for us for the first time – throughout the whole year.

We create more space for your servers!

Over the last couple of weeks and due to the turn of the year, it has been a little bit quiet here in our blog. But this does not mean that we have been idle during that time. Quite the contrary: Thanks to you, our valued customers and the many new customers we convince from our services each day, we are growing at a rapid pace and consequently, we need more space for many new servers 🙂

As a result, our technical team has recently put another room for server racks into operation in our data center in Nuremberg. On the picture below, you can see the false floor. In a first step, the cable trays for the network and power supply connection of the server racks were installed. Following this, we have assembled many new server racks!

If you would like to find out more: We provide an overview of our two data centers on our website!

Comparison of administration panels: cPanel vs. Plesk vs. Webmin

We are often asked which panel we would recommend. Since there is a variety of different panels with different functions and focus, we cannot easily answer this question. Currently we offer cPanel, Plesk, LAMP und Webmin, which we will introduce here.

cPanel/WHM

cPanel is a webhosting panel which allows to administrate a great number of users in an easy way and configure the installed services. In order to avoid security breaches many settings are pretty restrictive, which may cause issues due to the demands of your software. In addition, without plugins from external developers, it would not be possible to use nginx as an example. The software cPanel is divided into two parts, the interface for users is called cPanel, the administration interface WHM (WebHostMananger).

The developers provide a really detailed documentation which explains nearly all functions cPanel/WHM provides:

https://documentation.cpanel.net/

If errors occur or special questions appear which are not answered within the documentation, it is always a good possibility to ask for this within the official forum:

https://forums.cpanel.net/

And for those who do not know cPanel/WHM or want to check out what was changed before updating the own installation, a demo and the changelog are available:

https://cpanel.com/demo/
https://documentation.cpanel.net/display/CL/Change+Logs

If you are a new user, you may check out their YouTube channel, too:

https://www.youtube.com/user/cpaneltv

Plesk Onyx

Plesk understands itself as a platform for developers, thus it has a lot of software already installed and software like Docker, Ruby, etc. can be installed with a few clicks. In addition to this, a lot of features can be installed, using free or paid addons, which can be installed with a few clicks, too. Nevertheless, it is even an alternative to start a webhosting. At the moment, three different versions are offered, all details regarding the differences and the official addons can be found within the following document provided by Plesk:

https://www.plesk.com/wp-content/uploads/2017/03/plesk-onyx-licensing-guide.pdf

Plesk provides a detailed documentation, too:

https://docs.plesk.com/en-US/onyx/

In addition, a knowledge base with the most common problems and errors - and corresponding solutions - is provided:

https://support.plesk.com/hc/en-us

Moreover, the developers and community are active within the forum and provide assistance in case of problems:

https://talk.plesk.com/

Webmin

Webmin is no classic interface for webhosting, it is a server administration panel which provides a graphical interface to configure the installed services with the goal making server administration easier. An overview of the supported services can be found within the official documentation:

http://doxfer.webmin.com/Webmin/Webmin_Modules

In addition to the supported modules it is no problem to add additional software via SSH or develop more addons for Webmin to extend the list of services, this is possible due to the fact, that the source code is provided via GitHub:

https://github.com/webmin/webmin

As already mentioned, Webmin is by default no webhosting interface like cPanel or SSH but there was an additional software stack developed which provides the functionality required for webhosting:

https://www.virtualmin.com/

If you only want to use the server as a mail server, cPanel, Plesk and even Virtualmin may be a little bit to heavy, you can think about Webmin, too, since there is an additional addon which provides the basic mail server software:

http://www.usermin.com/usermin.html

LAMP

LAMP has already been offered since a few years and is not a panel like the other ones already mentioned, it is a software stack which contains (Linux,) Apache, MySQL and PHP; this is the basic software to start with your own web presentation. We already published a tutorial about this called "LAMP made easy".

Webmin + LAMP

After we had started offering LAMP, we were often asked why it is not possible to select both Webmin and LAMP. Since we always note down your feedback, we started offering both solutions as one package, so that you can start directly with your webpage after we have sent out the login details to you.

 

Conclusion

As you can see, there are different Panels on offer and the decision, which one to choose, also depends on the chosen operating system: cPanel can only be combined with CentOS, whereas Plesk can also be used with Windows Server. By the way: You can test Plesk one month for free (available for our VPS) and get used to the many functions this panel offers!
