Save yourself some time and tune the kernel tcp settings before testing with lots of connections, or your test will fail and you’ll see lots of Out of socket memory messages (and if you are masquerading, nf_conntrack: table full, dropping packet.)
Here are the sysctl settings I ended up with - YMMV, but these will probably do:
$ cat /etc/sysctl.conf
# General gigabit tuning:
net.core.rmem_max = 16777216
This guide will use either a macOS or an ArchLinux base system, to prepare a microSD card with Arch Linux for Raspberry Pi.
If someone managed to do the initial setup using Windows, please let me know, so I can add to this guide.
This guide will be verbose at times for some simple tasks. This is intended to help people just starting out, so it's not confusing. If something confuses you, let me know and I'll try my best to answer it.

This is a guide how to install mosquitto on Ubuntu with websockets enabled.
It is more or less the same as explained in the article "Six Steps to install mosquitto 1.4.2 with websockets on debian whezy" http://www.xappsoftware.com/wordpress/2015/05/18/six-steps-to-install-mosquitto-1-4-2-with-websockets-on-debian-wheezy/comment-page-1/
Exceptions:
rsync (Everyone seems to like -z, but it is much slower for me)
