Docker hub recently announced an upcoming request limit to their registry. So in order to reduce the amount of requests issued there, the idea of a caching proxy solution comes to mind. Possible solutions Fortunately there are some projects already working on that problem. However there are different approaches. Some of the projects I found […]

Wifi-Calling & firewall fun
I had observed odd firewall log entries from my cell phone and now I finally found some time to look into it. So here are my findings – maybe they help someone out there 😉 Traces in firewall logs So what did I observe: First of all my firewall complained about certain connections from my […]
What is IEEE 802.1X anyway? More and more companies run a shared desk strategy. Combined with the possibility of home office this often means that employees use their laptop both at home and at the office. The shared desk strategy however forces them to work at different work spaces (and connect to different network ports […]
As shown in my last post using wireguard over TCP (with a little help of proxyguard) isn’t that hard (once you understood how things work). However most VPN solutions come with certain limitations: They often use their specific ports and protocols and therefore can be filtered by firewalls (either by choice or even sometime by […]
Some time ago I tried to get eduvpn working with wireguard over TCP. As you might remember I wasn’t able to make it work reliably so I skipped that attempt for the time being. Now some time has passed and I decided to start over with a more basic approach to get a feeling about […]
Wireguard is a very nice and fast VPN solution, however it comes with some drawbacks: Most of all it only supports UDP traffic. On an open network this is not a problem, however some networks may deny UDP traffic or may even allow only very specific traffic (like (TCP based) http(s)). So to increase the […]
I’m planing to install eduvpn as a personal VPN solution. I also want to separate the VPN functionality (“vpn-daemon”, hostname “eduvpn-node”) from the management web frontend (controller or “vpn-user-portal”, hostname “eduvpn”). Adding software repository So we start by configuring the required software repos (on both machines, here’s the new APT822 version): Basic installation After that […]
I recently got a few NordVPN licenses, so I gave it a try. The GUI client on Linux seems extremely limited, so settings things up requires some good old shell commands. Basic installation/setup Documentation can be found here: At that point you’ll need to reboot in order to apply the new group membership (at least […]
