HAProxy on OPNsense Firewall with Let’s Encrypt

Posted on by

On an Alix APU, I run an OPNSense firewall with HAProxy and Let's’s Encrypt Plugin installed. I run the Read-It-Later Service Wallabag on Openmediavault, which I want to reach encrypted from the Internet. I have described the installation and configuration of Wallabag on Openmediavault here:Wallabag on Openmediavault The Alix APU’s can be found here: https://www.apu-board.de/ More information on Let’s Encrypt is available herehttps://letsencrypt.org/ We start with the configuration of Let’s Encrypt. First we put on Staging Environment, until we are sure, that our configuration is running. We still leave the plugin itself deactivated. Next we set up an account. Assign your hostname, than the url, to be operated with the certificate. An email address is also stored.[…]

Wallabag on Openmediavault

Posted on by

I describe here the installation of Wallabag as Docker Image on Openmediavault, the necessary, other components and their setup. The installation runs partly as a Docker image and partly as a native, on the OMV. This follows from this, that some OMV plugins are available, I prefer native operation or in my view it makes sense, central components, serving multiple clients, to operate outside of a container solution. The system sits behind an OPNsense that runs on an Alix APU. The firewall is responsible for the Let’s Encrypt certificate and the HAProxy listens on port 443 and takes care of the transfer of the requested connection to the respective server internally. At this point I assume, that OMV 4.X installed and[…]

IOS 13 and how to install and use fonts

Posted on by

It has been possible since IOS13, Install and use your own fonts as follows: The Fonts tab is under Settings -> General -> Fonts First install the FontDiner app: After installation, we open the app and switch to the Library tab and activate the fonts. Now we can find the fonts under Settings -> General -> Fonts. Unfortunately, the fonts cannot be used system-wide. With today's update of Pages and Keynote, the fonts can be selected in the respective application.

Displaylink Linux and double login

Posted on by

A display link is connected to my Lenovo laptop which I use 2 Operate monitors. Under Linux 2 Packages needed (Arch: displaylink, house) After installation I was able to do as requested 2 Operate displays, however, I always had to log on to the login screen 2 times sign up. To avoid double registration, page_flip must be deactivated. To do this, create the following file /etc/X11/xorg.conf.d/20-displaylink.conf with the following content: Section “OutputClass” Identifier “DisplayLink” match Driver “house” Driver “mode setting” Option “AccelMethod” “none” Option “PageFlip” “false” EndSection

Windows migration 10 VirtualBox Guest according to KVM

Posted on by

Due to lack of performance on my Linux notebook, Windows was running 10 Guest on VirtualBox not performant enough. After a little research I found a benchmar, the VirtualBox and KVM compares: https://www.phoronix.com/scan.php?page=article&item=virtualbox-60-kvm&a% 20 =% 203 KVM seems to perform better. I wanted to test that. First the hard disk of the source system is converted into the desired target format: qemu-img convert -f vmdk -O qcow2 /Virtual/Box/win10-disk001.vmdk /KVM/win10/win10.qcow2 Now a new virtual machine is created in virt-manager. Sata is used as the controller for the converted hard disk. It is best to add a virtual CD-Rom and insert the Iso image of the Fedora drivers. The current drivers can be downloaded here: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/archive-virtio/ Now we start the machine. In Windows we select the CD-Rom drive and install the guest[…]

Check the availability of a website with wget

Posted on by

The ping command is usually used to test the accessibility of a server. But it can happen, that a ping command is successfully executed, the corresponding website cannot be reached. To test this case, I wrote a little script, that tried with wget, go to the website.

Linux Terminals

Posted on by

For a long time I was looking for the right terminal for my purposes. I am a follower of the Gnome philosophy which I think does everything right with their DE. But this should be a matter of taste. So it made sense for me to use the gnome terminal with transparency. Guake was used as the dropdown terminal. I have been working with the i3wm for a long time now and since switching to my new Lenovo T470P, I also wanted to take a little care of the beauty and functionality of my system. I started to deal with the terminals and came across a post, who dealt with one point, that has long been a thorn in my side. It's about the text selection in[…]

Lenovo T470P with Docking Station on Arch Linux

Posted on by

The Lenovo T470P is almost completely supported by Linux. The fingerprint reader is an exception, that is not supported. The T470p differs from the T470 in a changed CPU configuration and the lack of a USB-C / Thunderbolt connection. There is an overview here: https://wiki.archlinux.org/index.php/Lenovo_ThinkPad_T470 I am using the device with a Lenovo Docking Station, which works out-of-the-box well. Compared to my previously used W530 a dream, because there the docking with an external monitor could only be operated using bumblebee due to the built-in Nvidia graphics. Only the sound could not be output via jack but only via Displayport. A short research turned out, that the problem has already been reported as a bug: https://bugzilla.kernel.org/show_bug.cgi?id = 195161 With the release of Kernel 4.15.5[…]
