Citrix on Fedora32
In case you need to get Citrix working under Fedora these are the steps that worked for me: First of all download the client from https://www.citrix.com/de-de/downloads/citrix-receiver/linux/receiver-for-linux-latest.html and make sure you download the WebReceiverOnly package as the Selfservice-Package needs webkitgtk to work which is not provided by the Fedora32 repository. Install client and crypto-libs Update libcrypto reference in desktop file Extract system ca-certificates and install in the Citrix cacerts directory Citrix Receiver expects libidn.so.11 so you need to link it to 12.6: Then start your Citrix application via the downloaded ica-file

Unfortunately Windows is still neccessary to do taxes online in Germany (with Elster – Elektronische Steuererklärung). Thats why I need to run Windows on a virtual machine on top of my Debian 10 / Gnome System. With Gnome theres “Gnome Boxes” coming, a interface for QUEMU. While Boxes allows to install and run VMs quite easily working on it through a virtual Windows Interface, is slow and lacks performance. Windows offers gui access through RDP (Remote Desktop Protocol), which is quite fast and comfortable, but even after extensive search and fixing attempts I have not managed to create a bridged...

After having put 4 or more running LXC-containers on the Turris I was disappointed with the speed of the systems that were installed. To be honest: I was using the Router as a server for my whole internet services and thats not what its designed for. Despite the speed everything was working flawlessly, so kudos to the openwrt- and the Turris-Team. I was asking myself how many virtual servers i essentially needed and came up with quite a number for my little homeserver: Webserver for https://arvidortwig.de with WordPress (so Apache, PHP and SQL) plain html Nextcloud (also Apache, PHP and...
