KVM | Resize Virtual Machine using LVM

Hello there. Today I want to take a look at how to resize a virtual machine that uses LVM for its vdisks. As I mentioned in a post before, I am using primarily LVM for VMs on my servers. This makes resizing the disks a bit more of a process

Aruba 2930F base, Device-Profile and VSF configuration

Hello there. This is technically a continuation of the "Aruba 8360 Basic and VSX configuration" post, which is part of a larger project. But I will separate it since this is different hardware. Most of this will be similar to the Aruba 3860 configuration. The main differences will

Incremental Backups of KVM virtual machines on LVM with Borgbackup

Hello there. I am currently running two home servers with KVM for the virtualization. Mentioned it a few times already. For the vdisks I am using LVM which should give me a tiny bit better performance since the VM does not have to go through an additional layer in form

Wireshark remote capture Sophos SG traffic over SSH (Linux)

Hi there. there are a few options to track traffic in Sophos, but none are as in-depth as tcpdump (as far as I am aware at least). The problem here is, that it is not as intuitive to capture the packages, copy the pcap file locally on your PC, and

Simple Wake on Lan Script

A short one today. In my last post, I mentioned my "home server". That thing actually does not run 24/7, even though it's a "server" (electricity is quite expensive here). There is no point in it running when I am not home and/

CentOS 8

Installing required modules for Supermicro AOC SAS2LP-MV8 (Marvell 88SE9485) in CentOS 8/Rocky Linux 8 (Update)

This took me a while to figure out... So I have a "home server". It is basically a lot of old hardware thrown together with a bunch of hard disks, running CentOS 7 with KVM for the virtualization. A few months ago I decided to upgrade to CentOS

How to get the backup file from a non booting/dead Sophos SG

Hey there. This will be a shorter one. A few weeks ago, I had a weird issue with a customer, where two Sophos SG 135 in an active / passive cluster died at the same time. They started to "only" drop a few packages at first, but slowly declined

Run GNS3 VM on KVM | Fedora Linux (Part 1)

Part 1Part 2 So... I have been using GNS3, to run my Network Simulations for a while now. Mainly to try out and learn new things, but also to test new configurations for customers, before implementing them. I also like it as a teaching tool for the new trainees. That&

Powershell connect to O365/M365 on Fedora Linux (Update)

(Update) Small update to this post. I changed the recommendation to the "alternative way". I think it works much better, since the release of V3. The first real post will be a short one. Last week there was an issue on a customers M365 tenant, which required a
