 A while back I decided to install Fedora in my old Laptop Gateway M-6806m and used it to test random things like Grafana, Docker, etc.   In the last weeks pi-hole was installed to test it as a docker container instead of the installation done in my Raspeberry Pi 2 Model B , for that I used instead the Gateway laptop.   So, it was really strange to see "fedoraproject.org" in the pi-hole section "Top Permited Domains" Ater a fast search with qwant.com found the answer in Reddit with the same question so, I'm keeping a copy of the answer here for my self (and you) 'cause I don't see the point to keep "asking" the DNS sever about that domain name even when I randomly use this laptop. r/Fedora 1 yr. ago unconcious_insomnia Question: How to stop periodic DNS queries for fedoraproject.org Was just looking at DNS logs while nothing is running. Constant DNS queries for fedoraproject.org without anything running. Edit: Solved by u/aioeu | rpm-ostree o...

I'm doing a hardware upgrade to this  old   laptop by upgrading the RAM from 2G to 4G, removing the DVD and adding a caddy to store the original hard drive were the DVD was and a new SDD to install the OS instead of the original HDD. The caddy I gouth is a PATA IDE to SATA, 12.7mm to connect the original HDD, which you can see over the DVD and the SSD already connected and protected by that metal "cage" to the left. Now, you can see the original RAM installed and the new 4G protected with the envelops they were sent by the provider: And now, these are the brand new 4G RAM installed:  Now, this is how it looks the caddy taking the place and simulating being the DVD (at the bottom): The old BIOS detects the new RAM installed: But I had a problem with the BIOS to put the SSD as the primary boot device and the HDD as secondary,  somehow the HDD went to the "bottom" of the options and it was complicate to put it below the SSD. When I finally got the drives in the boo...

In the last days/weeks I'm seeing people talking about "AdGuard" instead of "pi-hole" so I decided to give it a try. These are the steps I followed to install it using the Raspberry Pi 2 Model B where I have pi-hole running at the moment. First, stop/disable pi-hole: pi@localhost:~ $ pihole disable   [i] Disabling blocking   [✓] Reloading DNS service   [✓] Pi-hole Disabled pi@localhost:~ $ sudo systemctl stop lighttpd pi@localhost:~ $ sudo systemctl disable lighttpd Synchronizing state of lighttpd.service with SysV service script with /lib/systemd/systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install disable lighttpd pi@localhost:~ $ sudo pihole disable   [i] Blocking already disabled, nothing to do pi@localhost:~ $ sudo systemctl stop pihole-FTL pi@localhost:~ $ sudo systemctl disable pihole-FTL pihole-FTL.service is not a native service, redirecting to systemd-sysv-install. Executing: /lib/systemd/systemd-sysv-install disable pihole-FTL Now proce...

A couple of years ago, wife needed a new laptop and bought a new notebook, the "STAR WARS™ Special Edition Notebook" specifically... because "star wars". You can see the model here: https://www8.hp.com/us/en/campaigns/HP_Star_Wars_laptop/overview.html She decided first to use the Windows  OS and later to have dual OS having Windows and GNU/Linux.  Some time later she went full with GNU/Linux distribution. November 11th - The notebook started to fail at boot, you can imagine that after this time the hard drive could have issues and that's what we confirmed. She'll buy a new hard drive... some time in the future. November 30, 2019 the future was that day and the 1TB hard drive was dead. When we had the new hard drive installed and ready, we tried with OpenSuSe but after the installation was done and first boot completed, it felt "slow" and we considered it was too much for this laptop and we decided to try with Mint. Agai...

In the last months I've been using pi-hole to block ads/trackers/etc, here's a guide based on the official document and examples found on different sites/blogs. I'm using a Raspberry Pi 2 Model B along with raspbian  - Download/install/configure pi-hole # curl -sSL https://install.pi-hole.net | bash The installation script runs and you'll be shown the following: "This installer will transform your device into a network-wide ad blocker! " The next step requires you to provide the DNS upstream servers, consider using the Cloudfare DNS servers 1.1.1.1 and 1.0.0.1  or the DNS server you want. The installation is done and you should get the message: Installation Complete! The next steps depends on your home network configuration, on your router find the section where you set the DNS server and use the ip address that you configured for pi-hole. Now, open your favorite web browser and point it to the ip address assigned to the h...

I've been trying to install the Brave browser on CentOS 7 for some time now. The problem was that you had to use an option that is not considered safe to make it work and I opted not to use it that way. Today I went back to check the progress made and if a new option was available to get it installed/running with CentOS 7 (release 7.7.1908). The good news is yes but ,  you have to use a specific version . If you are using CentOS 8 the instructions here might work for you, if you are working with CentOS 7 don't follow them because as stated by " fmarier " on this link : < Given that CentOS 8 is now out and that we do not currently have the resources to do the work necessary to fix the glibc and the keysigning issues specific to CentOS/RHEL 7, we have decided not to support that version at this time and to instead allocate our time to the Linux distros which are currently working. > So, how do we install Brave?!  Here's another li...

After you complete your favorite option (Workstation, Server, etc) of CentOS 8 as a virtual machine using VirtualBox you're going to need to install the following packages (note that I'm  using 'dnf' instead of yum which is a softlink): # which yum /usr/bin/yum # which dnf /usr/bin/dnf # ls -ld /usr/bin/yum lrwxrwxrwx. 1 root root 5 May 13 14:34 /usr/bin/yum - dnf-3 # dnf install kernel-devel-$(uname -r) kernel-headers perl gcc make elfutils-libelf-devel After this, you can proceed as usual to the VirtualBox menu "Devices" and choose the option at the bottom "Insert Guest Additions CD image..." And follow the usual steps when a window pop-up asking you to run the script and proceed with the compilation/installation of the module. What follows is the output of the installation of the packages from previous command (if you choose the "workstation" option: # dnf install kernel-devel-$(uname -r) ker...
