You would like to access your home computer, but don’t know how? Does your home network with its constantly changing IP addresses jack up your monthly bill? Dynamic DNS services (DynDNS) can help you out. Find out which DynDNS providers are the best and what the advantages and disadvantages of each are in this overview.
Raspberry Pi is an inexpensive small form factor PC that can behave like a standard computer in many respects. Users can use this innovative mini-computer for all kinds of functions, from setting up an operating system to surfing the web, to using it as a server or a media center, and much more besides. Discover 10 interesting Raspberry Pi projects to try out at home.
The duel between Linux and Windows may have an obvious victor on the home computer front, but the battle for server use paints a very different picture: since the beginning, Linux has defeated Windows, as usage figures show. But many users remain unconvinced by statistics and rightfully ask the question: what are the actual differences between the two platforms?
If two computer systems are to exchange data, they must agree on a common protocol basis. For example, the selected transport protocol determines how the information is to be transferred. One of the more recent representatives of this protocol division is the Stream Control Transmission Protocol (SCTP), which the IETF (Internet Engineering Task Force) published in 2000 as an alternative to known...
The Internet protocol family – the cornerstone for communication on the Internet – has around 500 members who work on a wide variety of layers. For example, the connectionless User Datagram Protocol (UDP) is responsible on the transport layer for the transmission of packets that were previously addressed via the Internet Protocol (IP). In this guide, you can find out exactly what distinguishes...
As Android smartphone users will know, a complete backup of the operating system can only be created with the internal backup function that leaves a lot to be desired. The solution? Using a cloud storage solution like Google Drive. However, if you don’t feel comfortable handing all your data over to Google, you will have to search for another online Android storage option to back- up your personal...
A virtual private network (VPN) hides internet users in the network, and protects them from targeted attacks. With the help of VPN services, barriers between countries via geo-blocking can also be overcome. There are now numerous VPN providers based in very different countries. Some offer particularly stable servers, although all of them have their own strengths.
The “pathway to hell” – this is how Eran Hammer-Lahav once called the security protocol OAuth 2.0, on which he himself had worked for years. Others, however, use the service without issue. It enables users to use data and functions across multiple platforms in multiple services – for example, with the convenient single sign-on – using secure API authorisation. But how exactly does OAuth2 work and...
Online activity could be so simple – just enter your access data once and automatically be logged in for all accounts and services on the web, instead of having to remember dozens of passwords. This is, in fact, a reality for many websites, and the process is called SSO – single sign-on – and is becoming ever more popular among private and professional users. But what are the benefits of SSO, and...
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.
