Rustdesk

June 13, 2026

What is Rustdesk?

RustDesk is an open-source remote desktop software that allows you to access another PC’s desktop, for example to help friends and family when they have problems, or let them help you.

It is a free alternative to TeamViewer, AnyDesk, and similar programs.

A client application is needed on both PCs. A remote desktop access is only possible when the client is started, access is impossible without the Client being started, so the user is always in control.

How to install:

Download the latest Rustdesk client from here: https://rustdesk.com
Once downloaded, start the file:

In the lower left corner, click on “Install”.

Adapt to your needs and click on “Accept and install”.

Afterwards, you should have an Icon for Rustdesk on your desktop, and Rustdesk should be running:

Click on the “three dots” (as marked in the picture), select “Network” and click on “Unlock network settings”, the select “ID/Relay server”:

Fill the fields with the following data:

rustdesk.landrocks.world
rustdesk.landrocks.world
https://rustdesk.landrocks.world

It should look like this:

Press OK, and click on “Home” in the upper left corner.

Congratulations, you have successfully installed a Rustdesk client on your system.

How to use Rustdesk:

On the left side you see your ID and your password. If you give this to somebody else, he or she can access your desktop.

If somebody else gives you his/her ID from their left side of the window, you can access his/her desktop by entering that ID in the “Control Remote Desktop” field and clicking “connect”.

Amazon Echo devices cannot be pinged, here is an alternative

May 16, 2026

I want my Home Automation to check if my Amazon Echo devices are present on the network or not. However, Amazon Echo devices cannot be pinged.

NMAP comes to your help (If you do not have NMAP installed, apt install nmap should solve the issue).

The following code will give you a 1, if the Amazon Echo device is present at the given IP address. It gives you a 0 if not.

nmap -T4 -F 192.168.178.120 | grep "host up)" | wc -l

Clean/Format a USB stick that windows cannot handle anymore

May 16, 2026

OK, you need a Linux based system to do so.

Without the Memory stick being plugged into the Linux system,use the following command:

lsblk

Now plug in the usb Memory stick and use that command (again):

lsblk

The “new” device name should be easy to spot


Now, flaten the content of the Memory stick by using

mkfs.ext2 /dev/sdX

where sdX is the device name you found with lsblk.

Check which program hinders windows going to sleep

May 16, 2026

Todo: Fix last two broken screenshots…

Sometimes, windows doesn’t go to sleep when expected. Here is a little hint on how to find out which program is the reason.

Open a command window by right clicking on the 4 blue tiles and select “Terminal (Admin)”.

If the following window pops up, select “Yes”.

Enter the following command:

powercfg /requests

Now, the processes which hinder windows from going to sleep are shown. In this case there was a youtube video running in a browser window.

After closing that browser window, the problem was gone and all sub systems had the status “None.”
