    Installing Virtualbox Guest Additions on Debian 11

    I have been working with Debian 11 and running docker on it to host a few applications at home. As per best practice, I setup a virtual machine to test configs and updates first before deploying it to my production infrastructure.

The Virtual Box Guest Additions makes features such as copying and pasting between the host OS and virtual machine as well as running the virtual machine in full screen. This article has a good write up on what the Guest Additions provide you. I used this article as…

    Kernel driver not installed (rc=-1908) and modprobe vboxdrv

    I created a new VM in Virtualbox on my Pop_OS! machine to install Rocky Linux but received the below error when trying to start the virtual machine:             A quick search on the internet took me to the solution in this post. Thanks to Ali Razmdideh for the answer. I’m posting the steps here in case I need to find it again quickly.

    ESET NOD32 for Linux needs the following packages to install: libc6-i386, /lib/

    I tried to install ESET Antivirus on one of my machines and received an error stating: “ESET NOD32 for Linux needs the following packages to install: libc6-i386, /lib/“ I had to install libc6 but just running an apt install libc6 showed that I already had libc6 installed. After some head scratching I noticed the -i376 (doh!) and installed the missing dependency using: sudo apt install libc6-i386 which resolved the issue and I was able to install ESET Antivirus.

    Unable to browse samba shares when internet connection is down

    We’ve been having a lot of outages on our internet connection and I noticed that we are unable to browse the samba shares on our CentOS 7 server. After some searching on the internet I saw a few comments around adding the server’s host name and IP in it’s own hosts file. I proceeded to open /hosts/etc and added the IP and server name to the hosts file. Sure enough I could now browse my samba shares on the server with our internet being down.

    Installing Manjaro

    I started using Manjaro on my laptop and found that installing applications and using it differs quite a bit from the Ubuntu distributions that I am used to. I started this mini series to show how to use it, install the OS, install applications and show off some features I found that works great. The below video shows the installation and some features of Manjaro using the Gnome desktop environment.

    Redesign of my home network

    I have started a redesign of my home network. In short I installed and configured an OPNSense firewall with the WAN, LAN and Wifi segmented. More on the OPNSense installation later. I will be moving my CentOS file server and all current networked devices behind the OPNSense firewall. This includes all PC’s, Raspberry Pi’s, Televisions etc.
