When running a highly available Kubernetes cluster with multiple control plane nodes, you need a load balancer to distribute API traffic across all control plane endpoints. This guide walks through setting up HAProxy 3.2 on Debian to load balance both the Kubernetes API (port 6443) and Talos API (port 50000). Architecture Overview Component Address Port Purpose HAProxy LB 192.168.66.160 6443 Kubernetes API HAProxy LB 192.168.66.160 50000 Talos API HAProxy LB 192.168.66.160 9600 Stats Dashboard Control Plane 1 192.168.66.161 6443/50000 talos-lon-cp01 Control Plane 2 192.168.66.162 6443/50000 talos-lon-cp02 Control Plane 3 192.168.66.163 6443/50000 talos-lon-cp03 Prerequisites Debian Trixie (or compatible) server for the load balancer Network connectivity to all control plane nodes Root or sudo access on the load balancer server Install HAProxy 3.2 HAProxy 3.2 is available from the official HAProxy Debian repository. First, add the repository signing key and apt source: ...

This guide walks through setting up a highly available Talos Linux Kubernetes cluster with 3 control plane nodes and 2 workers, featuring KubeSpan for encrypted node-to-node communication and Tailscale integration for secure remote access. Cluster Overview Node Hostname IP Address Control Plane 1 talos-cp01 172.16.18.231 Control Plane 2 talos-cp02 172.16.18.232 Control Plane 3 talos-cp03 172.16.18.233 Worker 1 talos-worker01 172.16.18.241 Worker 2 talos-worker02 172.16.18.242 VIP Endpoint - 172.16.18.222 Prerequisites Talos Linux installed on all nodes (using nocloud image) talosctl CLI installed on your workstation Tailscale account with an auth key Network connectivity to all nodes Environment Setup Set up the environment variables for your cluster: ...

Introduction Talos Linux is a modern, minimal, and secure operating system designed specifically for running Kubernetes. Unlike traditional Linux distributions, Talos is immutable, API-driven, and removes SSH access entirely—making it ideal for production Kubernetes clusters. In this article, I’ll walk through how to provision a complete Talos Kubernetes cluster on Proxmox using OpenTofu (an open-source Terraform alternative). This approach leverages infrastructure as code to create reproducible, version-controlled cluster deployments. Architecture Overview Our cluster will consist of: ...

Ideally use 1 # subscription-manager unregister Otherwise: 1 # rm /etc/sysconfig/rhn/systemid should do the trick.

!!!! THIS IS FOR EDUCATIONAL PURPOSES ONLY !!!! These instructions are for setting up and running OpenBTS with Nuand’s BladeRF x40 Board. These are a work in progress and should be taken as is. This was possible with the help of @mambrus on #bladerf and @rwr on #bladerf, and is a collection of different how-tos linked at the end of the post. OS Used: Ubuntu 12.04 LTS Server 32 bit, The ISO can be downloaded from here ...

Was playing around with Mbuni for a friend of mine, who wanted to use it as a VASP gateway and interconnect it with an operator over MM7. Spent a little while configuring it and thought of posting the configs here for anyone who’s trying to achieve a similar configuration. Mbuni consists of: MMS Relay MMS Proxy MMS From Email MMSbox For this specific purpose, only MMSBOX is required. I expect that you’re already familiar with either Kannel and/or Mbuni’s basic configuration. So I’ll just focus on MMSBox MM7 integration. ...

ISPs in PK don’t generally allow incoming traffic to your public IP rendering it useless, this is a real pain when you want to access your machine from a remote location. The solution to it is a reverse ssh tunnel, which will work in the following way: [Home Machine] ==> {Middle Machine} ==> {You} So you’ll map a port from your home machine to your middle machine, which when connected to from the middle machine will forward all traffic to your home machine. I’ll give an example on how to achieve it. ...

Here are the SIP settings if you want to use your VoIP number from Mobilink Infinity on a softphone. Disable SIP ALG You’ll have to first logon to your CPE admin interface, browse to NAT -> ALG and uncheck SIP ALG, then click Apply. If you use an outdoor unit, do the same with the outdoor CPE as well. X-Lite Configuration Fire up X-Lite and configure it with the following settings: ...
