Testing the Internet: availability - stability, disruption?

created: 16.05.2022 from Bernhard

More important than the speed of an Internet connection is its availability. If the Internet line does not run stably, this can have several causes. The basis for the connection is of course provided by the provider, who guarantees his customers the highest possible availability. If you operate a router, switch or other devices in your home network, you expand the circle of possible sources of error to include the corresponding devices. In addition, the availability for the individual end device... ... continue reading

Windows : create a missing recovery partition

changed: 14.05.2022 from Bernhard (Initial Release: 15.05.2022)

When cloning a large hard disk to a smaller one, I lost the recovery partition. So far not bad, Windows works without recovery partition, but in case of an error the partition helps to get the PC up and running again. To summarize, here's how it works with the recovery partition: As long as the partition is still there, it can be deactivated and written to a file. If the partition gets lost unexpectedly, it can be recovered from the Windows setup media. This post is also available as a vide... ... continue reading

changed: 13.05.2022 from Bernhard (Initial Release: 04.05.2022)

In order to operate several web services with corresponding SSL certificates on one server, the Letsencrypt-nginx-proxy-companion can be used. The setup is a reverse proxy that handles SSL offloading and certificate management. Once the proxy is started, the companion takes care of the provisioning of multiple websites over a common IP and its certificate management: for issuing certificates for new containers and renewing them for existing containers: everything on the fly and within a few seco... ... continue reading

The best AntiVirus? Is Windows Defender enough antivirus?

changed: 11.05.2022 from Bernhard (Initial Release: 12.05.2022)

In times before Windows 10, the use of an own AntiVirus program was necessary to run the PC reasonably safe. Initially, Microsoft did not offer a solution here at all, later, in Windows 7, the Microsoft AV could be installed later under the name Microsoft Security Essentials and since Windows 8, an anti-virus protection is integrated in Windows, theĀ "Windows Defender". Windows Defender can be found in the settings under"Virus & threat protection". To make it appear that the firewall works in... ... continue reading

use dd to clone the hard disk block by block or create an image

created: 11.05.2022 from Bernhard

The Linux command dd can be used to write one hard disk block by block to another. Since all blocks are transferred, it does not matter which file system, partition layout or operating system is to be cloned, only the target hard disk should not be larger than the partition layout of the source hard disk, see: cloning a large hard disk to a smaller one using free tools. ... continue reading

clone a large hard disk to a smaller one with the help of free tools

created: 11.05.2022 from Bernhard

Free tools for cloning a hard disk cannot usually clone a large partition and thus a large hard disk onto a smaller one. Thanks to the command "Shrink Volume" in the disk management of Windows, the hard disk can be prepared for the cloning process and then cloned with the help of open source tools. Thus, for example, a Windows installation with all data can be moved to another disk.To speed up the PC with very little effort, a smaller SSD is usually used as the target. With the procedure describ... ... continue reading

WLAN and LAN network cable simultaneously - Internet access

What actually happens when WLAN and the network cable are connected at the same time? The routing table provides the answer to this question. By adjusting the routing or the metric in the TCP/IP settings of the adapters, the desired behavior can be set. If you want to see the settings noted here in action, you can do so in a short video. ... continue reading

Find IP addresses in the network even if their firewall is enabled

If you want to get a quick overview of all active devices in a network, you can do this with network discovery, commands in the command prompt, in PowerShell or with special IP scanners. The PowerShell commands presented at the beginning of this post give a quick overview of all devices on the local network and may make special programs for scanning the network unnecessary. ... continue reading
