For the past 30 years, the file transfer protocol (FTP) has supported computer users with the transfer of data in TCP/IP networks. FTP servers enabled not only the upload but also the download of files, in which each access is controlled via a separate connection. In this Ubuntu FTP server tutorial, you’ll learn how to install, configure, and run your own server under the Linux distribution.
Whether a home PC, work laptop, or website server – without an operating system, the management of hardware resources wouldn’t be possible. Windows systems have proven themselves over the years, and Apple computers run with Mac OS X as the standard, but Linux distributions are no longer a niche in the server environment. Ubuntu, for example, continues to build on traditional open source...
FileZilla is considered to be the standard in software for transferring data between locally connected computers and online servers. The network protocol is able to transfer via FTP and its encrypted variants, SFTP and FTPS. We’ve created an overview of the client program’s features and break down the details of this program from installation to data transfer.
Computer systems and applications use time stamps for communication purposes. Synchronous system times are highly important for these so-called temporal signatures to be of any use – especially for systems that exchange information via the internet. A protocol that has provided valuable assistance for decades is the network time protocol (NTP) – here is an introduction to NTP, as well as some...
Traditionally, cloud solutions are designed for central data processing. IoT devices generate data, send it to a central computing platform in the cloud, and await a response. However, with large-scale cloud architectures, such a system inevitably leads to bandwidth problems. For future projects such as connected cities and smart manufacturing, classic cloud computing is a hindrance to growth. The...
Autonomous cars, intelligent factories and self-regulating supply networks – a dream world for large-scale data-driven projects that will make our lives easier. However, what the cloud model is and how it works is not enough to make these dreams a reality. The challenge of effectively capturing, evaluating and storing mass data requires new data processing concepts. With edge computing, IT...
Try and imagine a world where you don’t have to memorise passwords: Thanks to FIDO2, this could soon become a reality. Authentication in online shops or for online banking can be done through a fingerprint or hardware token. The latter can communicate with laptops of PCs through a USB, NFC or Bluetooth. To enable conversations between two devices, FIDO2 uses the Client to Authenticator Protocol...
Assuming that you’ve already decided that Kubernetes is the way to go, this article will provide a comparison of public cloud vendors to assist you when deciding where to run Kubernetes. It’s important to understand the main features and capabilities of the main cloud providers before choosing your target platform.
Many people use several devices and have data stored on them. What should you do if your data carrier fails or the data gets lost? Backing up data is extremely important and an online backup makes perfect sense. By doing this, you don’t risk losing your important files due to a system crash or criminal activitiy. What is the best option? Here is a comparison of online backup service providers.
Passwords are not an ideal way to surf the World Wide Web safely. They are either so complex that they are hard to remember, or so simple that they can be guessed in next to no time. FIDO2 takes a different approach and relies on modern technology. The open standard has the potential to make surfing the net safer and more convenient at the same time.
Servers are what make up the physical basis of the internet. Setting up your own professional site, putting products online for sale, or connecting multiple company locations with one another: all of these tasks require the support of high-performance computers. And it doesn’t matter if you purchase hardware resources for your own data center or opt for the flexibility of cloud services: operating a server comes with the challenge of independently configuring and administering hardware components. But don’t worry, there’s a lot of support out there for these tasks. In the Server Guide of 1&1 IONOS’s Digital Guide series, you’ll find regular articles, news, and tutorials on how to operate this indispensable component of today’s IT infrastructure.
Packed with practical tips, our guide covers a wide spectrum of topics primarily aimed at mid-sized companies, freelance developers, and tech hobbyists. While some articles, like ‘What is a server?’ or ‘DNS – name resolution online’ cater more to beginners, experts are by no means left hanging; there’s a wide range of detailed texts and tutorials on important tasks like choosing the best operating system, filling security gaps, or getting the best possible performance out of your software and hardware.
If you take a look, you’ll notice our guide is divided into four different subcategories, each covering a different topic. The ‘KnowHow’ area sets out to familiarise beginners with the basics of operating a server. Details on different server types and how to use them are also laid out here. Tips and tricks on managing server software is found under the keyword, ‘Configuration’. The category, ‘Security’ is all about dealing with potential problems server operators may encounter from online threats. Conventional methods of attack, like viruses, worms, and Trojans, and what you can do to combat them are explained here. And the category, ‘Tools’, provides useful guidance on what resources can help make administering your server a more manageable task.
