Proxmox Container with Debian 10 does not work after upgrade

Howto install Wireguard in an unprivileged container (Proxmox)

April 14, 2019 Wireguard is the new star on the block concerning VPNs – and yes it has some benefits to the old VPN technologies but I won’t talk about them as there is much information about that on the Internet. This blog post just explains how to set it up in an unprivileged container. In my case everything is done on a Proxmox server. Let’s start: On the Proxmox…

Howto install Bitwarden in a LXC container (e.g. Proxmox)

As many of you know me, I’m quite serious about security and therefore a believer in the theory that a service which is not reachable (e.g. from the Internet) cannot be attacked as easily as one that it. Looking at password managers this makes choosing not that easy. Sure there is Keepass and the descendants, but they have the problem that the security is based solely on the master password…

QuickTip: Howto secure your Mikrotik/RouterOS Router and specially Winbox

I didn’t post anything about the multiple security problems in the Mikrotik Winbox API, as I thought that whoever is leaving the management of a router open to the Internet should not configure routers at all. Of course it is common sense to open the management interface only on internal network interfaces and to source IP addresses you’re managing the routers.  But as this is quick tip I’ll show you…

Some VPN providers leak your IPv6 IP address

Just a short note. Today a friend called me if I could help him to get TV streaming from TV stations in the US running. When I looked at it, he even selected a VPN provider which offers servers in the US to circumvent the Geo restrictions, but still it didn’t work. He showed me the NBC website where the first ad was shown and than the screen stayed black….

How to configure a Mikrotik router as DHCP-PD Client (Prefix delegation)

Over time more and more IPS provide IPv6 addresses to the router (and the clients behind it) via DHCP-PD. To be more verbose, that’s DHCPv6 with Prefix delegation delegation. This allows the ISP to provide you with more than one subnet, which allows you to use multiple networks without NAT. And forget about NAT and IPv6 – there is no standardized way to do it, and it will break too…

Tips / Solutions for settings up OpenVPN on Debian 9 within Proxmox / LCX containers

When I tried to migrate my OpenVPN setup to a container on my new Proxmox server I run into multiple problems, where searching through the Internet provided solutions that did not work or were out of date. So I thought I put everything one needs to setup OpenVPN on Debian 9 within a Proxmox / LXC container together in one blog post.   Getting a TUN device into the unprivileged…

Howto setup a Debian 9 with Proxmox and containers using as few IPv4 and IPv6 addresses as possible

My current Linux Root-Server needs to be replaced with a newer Linux version and should also be much cheaper then the current one. So at first I did look what I don’t like about the current one: It is expensive with about 70 Euros / months. Following is responsible for that My own HPE hardware with 16GB RAM and a software RAID (hardware raid would be even more expensive) –…

A security minded guy forced to buy a Wifi enabled cleaning robot

First I want to tell you all that I wanted a vacuum cleaning robot without Internet connection, but I couldn’t find one which fulfilled the requirements. At first I thought the DEEBOT M81 from ECOVACS would be such a device (vacuum and mop combo and possible to carry between rooms as it works randomly), but don’t buy it if you’ve stairs. On the first day alone at home it went…
