Practical step-by-step instructions, useful quicklinks, helpful information or FAQ – our documentation portal IT Center Help provides you with answers to countless questions about the IT Center’s services for studying, teaching and research.
Since its launch in July 2020, we have continuously optimized our portal based on your feedback and adapted it to your needs. Today, we would like to introduce you to two new features in IT Center Help, which you can now put through their paces. Read the rest of this entry »

Almost 12,000 people from more than 125 countries currently study, research, teach and work at RWTH Aachen University. This living internationality at RWTH Aachen University is accompanied by strategies, measures and services to promote the internationality of studies, teaching and research. RWTH Aachen sees itself as a member of a global scientific community. For this reason, we are now proud to announce that our RDM Blog can now also be read in English.
Always up-to-date with the status message portal!

Error message. Nothing works anymore?
Have you ever woken up in the morning, started to study or work on your PC, but then you got an error message and didn’t know what was going on? We have the solution! Especially for this purpose, we have the status message portal!
FAIR-Data Spaces – How does locally stored data get into the cloud-based data space?

On our FDM blog, we recently shared news about Gaia-X and FAIR-Data Spaces. FAIR-Data Spaces is a cloud-based data space for science and business, made possible and developed with the help of collaboration between Gaia-X and the NFDI.
The project
- designs the roadmap for collaboration between the two initiatives,
- clarifies ethical and legal frameworks for data exchange between science and industry,
- develops common technical principles
- and demonstrates the use of Gaia-X technologies for making research data available and usable along FAIR principles in different scientific disciplines and industries.
But how does local data get into the cloud-based data space? To show this data space from a user perspective, we would like to explain the process steps and the technical background in more detail.
Backdoors: Access Through an Alternative Access Point

In life, sometimes it can be very useful to have a plan B or to keep a backdoor open. But would you leave your house and hide the keys to the backdoor under the doormat? For burglars, this setup would probably be an easy target. In IT as well, so-called backdoors are a very popular target for hackers. However, these backdoors are much more tricky and discreet than an open door or hidden keys under a doormat. Because even when the original breach of security, such as an open window, no longer exists, cybercriminals can still get in and out as they please via the implemented backdoor.
Data backup made easy

With the year 2021 nearing its end, a whole new year full of possibilities is about to begin. Once again, the time has come for some good resolutions. This year has clearly shown us how essential a good IT infrastructure is. Day after day, huge amounts of data are created, processed and shared, both privately and professionally. But what if this data unexpectedly disappears? While many people may be aware of the danger of data loss, only a few actively take precautions to protect their data from such a loss in a private context. Frequent backups aim to prevent data loss and are an essential aspect of IT security.
The Metadata Form – Migrate Archive Nodes via Metadata

We know it too well ourselves from moves of all kinds: if we know what is contained in the boxes, it is much easier for us to decide whether we still want to keep certain contents or whether we can say goodbye to them. For this reason, we at least write on the box what is included and where it belongs.
The same goes for data that we want to archive, for example. We don’t have boxes available, but we can “label” the nodes to be archived with metadata. To do this, the appropriate node contacts receive a dedicated link to a metadata form about what exactly belongs to an archive node. What this is all about, you can read in this article.
Single sign-on: What does that actually mean?

Our everyday life is closely accompanied by the internet. We communicate with our peers on the net, share memories on social media, we shop online, search for answers to various questions in forums and much more. All these services usually require a login via username and password. With intensive use of various online services, it is sometimes easy to lose track of everything. This can often lead to downright password chaos. Single Sign-On (SSO) is intended to remove or precisely prevent this chaos. Read the rest of this entry »
One becomes two: Goodbye and auf Wiedersehen c6k-rog…Welcome n7ks!

Now it’s official: The c6k-rog was finally switched off from the network at the beginning of November 2021 and is now in a well-deserved retirement. The router, which was the main distributor for all institutes of the RWTH Aachen in the city centre for more than 14 years and routed the entire network, will now be replaced by the two new core routers n7k-carl-1 and n7k-sw23-1.
This means that one router has been replaced by two new, more powerful routers, which will guarantee the IT infrastructure at RWTH Aachen University in the future. This changeover was accompanied by the Network Division of the IT Center which operates the communication infrastructures of RWTH Aachen University. Read the rest of this entry »
Archive becomes DigitalArchive
New technology, familiar service, convenient access
The tape library is the home of the previously archived data. In the future, archiving will take place on S3 object storage.

December 08, 2021 is an important deadline for all users of the archive and all those who would like to archive data from administration, teaching and university operations in the future.
The contents of the current archive will be migrated to an object storage infrastructure beginning in December. We have already reported on the archive migration and will continue to keep you updated. The archive will therefore inevitably be set to “Read Only” from 08.12.2021. However, you can continue to use the archiving service, because the start of the new DigitalArchive will coincide with this date.
