Configure IPv6 for Proxmox Host via Slaac

The Proxmox server running at home only has an IPv4 statically assigned to it. Since I’ve been trying to get all my connected devices at home to get IPv6 assigned, I figured I should try with this Proxmox server next. I’m running Proxmox VE 8.0.4, and it’s based on Debian 12 (bookwarm). The settings for its network interfaces are stored in /etc/network/interfaces: root@pve:~# cat /etc/network/interfaces auto lo iface lo inet loopback auto vmbr0 iface vmbr0 inet static address 192.168.1.8/24 gateway 192.168.1.1 bridge-ports enp2s0 bridge-stp off bridge-fd 0 Here is the output of vmbr0 device: ...

Today, I need to redirect from one url path to another. It took me a while to get it right, and I’d better write it down before it’s forgotten. This is what I want: https://demo.example.com/login -> https//demo.example.com/demo/login. ...

The way I have it setup on my router, running OPNsense, is to set the “Router Advertisements” to “Unmanaged” with DHCPv6 disabled. “Unmanaged” for SLAAC (A flag), and SLAAC stands for Stateless Address Autoconfiguration.

How did I renew Red Hat Developer Subscription

If you’re reading this post, it’s quite likely that you’re fully aware that Red Hat provide a no-cost Red Hat Developer Subscription for individuals.

So today when I turned it on and logged into it, the following message came up when i tried to update the system: ...

Fix cc: error trying to exec 'cc1plus' on openSUSE Leap

It’s currently almost 23:15, and I’m already sleepy. Therefore, this is going to be a short note on how I fixed an minor but annoying issue nvim-treesiter (Neovim’s plugin) on openSUSE Leap (15.5). The error message is or was as below: nvim-treesitter[yaml]: Error during compilation cc: error trying to exec 'cc1plus': execvp: No such file or directory Press ENTER or type command to continue I don’t code in C++ nowadays, but the error looks like the C or C++ compiler was missing. But first, let’s show the version of openSUSE running on this instance, I mean VM: ...
