Ozark-Connect/NetworkOptimizer v1.15.6

on GitHub

One fix this release: the speedtest container now boots cleanly on kernels that don't have the BBR TCP module loaded. See v1.15.0 release notes for what's new in v1.15.0+

Fixes

• Speedtest container fails to start on kernels without BBR - The speedtest container previously tried to enable BBR congestion control via Docker compose sysctls, which hard-failed docker compose up on hosts whose kernel doesn't ship the tcp_bbr module (Synology, QNAP, some Proxmox / LXC setups). The sysctl is gone, and the container now inherits whatever CC the host has configured. If bbr is loaded and set as the default on the host, speedtests still use it; the entrypoint prints the current CC and, if applicable, shows the exact host-side command to enable bbr (modprobe tcp_bbr or sysctl -w net.ipv4.tcp_congestion_control=bbr).

  If you hit this error, grab the latest compose file and upgrade:

  curl -o docker-compose.yml https://raw.githubusercontent.com/Ozark-Connect/NetworkOptimizer/main/docker/docker-compose.prod.yml
  docker compose pull && docker compose up -d

  (macOS with port mapping instead of host networking: curl -O https://raw.githubusercontent.com/Ozark-Connect/NetworkOptimizer/main/docker/docker-compose.macos.yml && docker compose -f docker-compose.macos.yml pull && docker compose -f docker-compose.macos.yml up -d)

Installation

Windows: Download the MSI installer below

Docker:

docker compose pull && docker compose up -d

macOS (native, recommended for accurate speed tests vs Docker Desktop):

git clone https://github.com/Ozark-Connect/NetworkOptimizer.git && cd NetworkOptimizer && ./scripts/install-macos-native.sh
# or if you already have it cloned
cd NetworkOptimizer && git pull && ./scripts/install-macos-native.sh

Proxmox:

bash -c "$(curl -fsSL https://raw.githubusercontent.com/Ozark-Connect/NetworkOptimizer/main/scripts/proxmox/install.sh)"

For other platforms (Synology, QNAP, Unraid, native Linux), see the Deployment Guide.
