Networking tutorials
Configure network traffic shaping with tc and HTB for bandwidth management and QoS
Set up hierarchical token bucket (HTB) traffic shaping with tc to control bandwidth allocation, prioritize network traffic, and implement quality of service policies for optimal network performance.
Configure network load balancing with keepalived and VRRP for high availability failover
Set up keepalived with VRRP to create highly available network services with automatic failover. Configure virtual IP addresses that move between servers when one fails, ensuring zero-downtime load balancing.
Configure network interface bonding with LACP and failover for enterprise networking
Set up LACP bonding for high-availability network interfaces with automatic failover. Configure both Linux bonding drivers and switch-side LACP for enterprise network redundancy and increased bandwidth.
Configure network bridge interfaces for VM networking and container communication
Set up Linux network bridges to enable communication between virtual machines, containers, and physical networks. Configure bridge interfaces using netplan, bridge utilities, and implement security policies for production environments.
Configure Tailscale mesh VPN with subnet routing and ACL policies for secure network access
Set up a zero-trust mesh VPN network with Tailscale that includes subnet routing for local network access, granular ACL policies for security, and exit nodes for secure internet access.
Configure OpenVPN server with certificate management and client automation
Set up a production-grade OpenVPN server with Easy-RSA certificate authority, automated client configuration generation, and certificate revocation management for secure remote access.
Configure network bonding and VLAN tagging for high availability and network segmentation
Set up network bonding for link aggregation and failover protection while implementing VLAN tagging for network segmentation. This tutorial covers bond configuration with Netplan and NetworkManager across multiple interfaces.
Set up BGP routing with FRRouting for dynamic network routing and failover
Configure BGP routing with FRRouting to implement dynamic network routing, automatic failover, and high availability for enterprise network infrastructure with route filtering and policy management.
Automate WireGuard client management with scripts for provisioning and configuration
Create automated scripts to provision WireGuard clients, manage configurations, and monitor VPN connections. This tutorial builds comprehensive management tools for production WireGuard deployments.
Configure HAProxy with Consul for dynamic service discovery and automatic backend updates
Set up HAProxy with Consul integration for automatic service discovery, health checking, and dynamic backend updates. This tutorial covers consul-template configuration for zero-downtime scaling and failover in microservices architectures.
Configure Envoy proxy rate limiting and circuit breakers for microservices resilience
Learn to implement production-grade Envoy proxy with global and local rate limiting, circuit breakers, and health checks to build resilient microservices architecture that can handle traffic spikes and service failures gracefully.
Install and configure HAProxy for high availability load balancing
Set up HAProxy with SSL termination, keepalived for high availability, and comprehensive health checks to distribute traffic across multiple backend servers with automatic failover.
