Rsync over SSH - (40MB/s over 1GB NICs)

The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

  • a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
  • H: preserves hard-links
  • A: preserves ACLs

Mini tutorial for configuring client-side SSL certificates.

Client-side SSL

For excessively paranoid client authentication.


Updated Apr 5 2019:

because this is a gist from 2011 that people stumble into and maybe you should AES instead of 3DES in the year of our lord 2019.

some other notes:

Both things have been introduced recently, and let you access even private ec2 instances

  1. Without VPN
  2. No open SSH port
  3. Authentication / Authorization is fully delegated to IAM
# Assumes valid AWS Credentials in ENV

ESPHome PWM fan using a Wemos D1 mini lite
# Controlling my Buva Qstream ventilation system using:
# * A Wemos D1 mini lite (an ESP8266 based board)
# * A Wemos power shield so I can power the Wemos from the ventilation units 12V supply.
# * A simple PWM to 10V convertor like this: https://www.cheaptech.nl/pwm-signaal-te-voltage-converter-1-3-khz-0-10-v-pw.html
# * The amazing ESPHome firmware tool: https://esphome.io
# * Home Assistant to tie it all together: https://www.home-assistant.io
#
# I used to use a Raspberry Pi and some Python code for this. See https://gist.github.com/SqyD/a927ab612df767a0cc892bcde23d025c
# The Wemos approach seems more stable and doesn't require external USB power.
