Enabling SSH on Engenius EAP600 (and maybe other models)

This tutorial will walk you through the steps needed to get root SSH access on an Engenius EAP600 dual-band WiFi access point. SSH doesn't come enabled out of the box on these things, so if you want to SSH into the device (which is running an old version of OpenWRT), keep reading.

Fingerprint-based certificate validation in Python (including pin-sha256)

# For Python <3.7, we monkey-patch ssl.SSLSocket directly, because ssl.SSLContext.sslsocket_class
# isn't available until Python 3.7. For Python 3.7+, we set ssl.SSLContext.sslsocket_class
# to our modified version (which is sort of monkey-patching too).

# As the "bufferbloat" folks have recently re-discovered and/or more widely
# publicized, congestion avoidance algorithms (such as those found in TCP) do
# a great job of allowing network endpoints to negotiate transfer rates that
# maximize a link's bandwidth usage without unduly penalizing any particular
# stream. This allows bulk transfer streams to use the maximum available
# bandwidth without affecting the latency of non-bulk (e.g. interactive)
# streams.

View elligator2.h
There used to be something that resembled an Elligator2 implementation here ported from agl's
Go code. The implementation is unmaintained and has severe issues (as pointed out in a comment),
and should not be used for anything.

Setting up ISC dhclient on debian / ubuntu for prefix delegation
View README.md

My ISP (Time Warner Cable) hands out IPv6 addresses with DHCPv6; it will delegate a /56 if asked. So long as I keep refreshing the lease, it won't renumber me. I have my cable modem set to bridge, and do all the firewalling, NATing, etc., on a Debian box. In what follows, eth0 is the internal interface.

The dhclient that ships with debian/ubuntu does not support asking for a prefix delegation, so I had to build one from sources.
