Cowboy, the popular Erlang web server, has deprecated middleware and replaced the concept with stream handlers, a more flexible, but more complicated API. This page contains a documented reference implementation of a stream handler, to help others when developing their stream handlers in the future.

Add tailscale to an EdgeRouter and surviving system upgrade

Adding tailscale to an EdgeRouter (and surviving system upgrades)

I suggest you run sudo bash on all of these so you're the root user.

Installing

  1. Download tailscale and put the files in /config/. Find the latest stable or unstable version for your EdgeRouter's processor (ex. ER4 is mips and ERX is mipself)
sudo bash    # if you havent already

open-vm-tools and VMWare Shared Folders for Ubuntu guests

(NB: adapted from this Ask Ubuntu thread -- tested to work on Ubuntu 16.04 LTS through Ubuntu 22.04 LTS (Jammy).

Unlike using VMWare Tools to enable Linux guest capabilities, the open-vm-tools package doesn't auto-mount shared VMWare folders. This can be frustrating in various ways, but there's an easy fix.

TL;DR

Install open-vm-tools and run:

sudo mount -t fuse.vmhgfs-fuse .host:/ /mnt/hgfs -o allow_other
