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

Hi there. I switched from Windows 10 to Fedora Linux (Plasma 5) on my work laptop a couple of months ago and I am quite happy with it so far. There are a few annoying things, like detaching and reattaching the laptop to the docking station causes the external displays

Part 1Part 2 Hey there. This is part 2 of my Aruba 8360 basic and VSX configuration. In this part, I want to go through the VSX and LAG/LACP configuration. I said I would do the configuration on the physical device. This turned out to be a bit of
Sophos XG
Hi, a quick one today. We have a customer with a Sophos XG 230, a lot of Site-2-Site VPNs and different Policy-based routes, mainly for the 3 different ISPs they have. The default "route precedence" the Sophos XG uses is as follows.: 1. Static routes 2. SD-WAN policy

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

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&
