EC2 Instance Connect meets AWS Session Manager via SSH

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

LVM cache in Debian

From the man-pages: "The cache logical volume type uses a small and fast LV to improve the performance of a large and slow LV. It does this by storing the frequently used blocks on the faster LV. LVM refers to the small fast LV as a cache pool LV. The large slow LV is called the origin LV. Due to requirements from dm-cache (the kernel driver), LVM further splits the cache pool LV into two devices - the cache data LV and cache metadata LV. The cache data LV is where copies of data blocks are kept from the origin LV to increase speed. The cache metadata LV holds the accounting information that specifies where data blocks are stored (e.g. on the origin LV or on the cache data LV). Users should be familiar with these LVs if they wish to create the best and most robust cached logical volumes. All of these associated LVs must be in the same VG."

Assuming LVM is already setup in HDD (e.g. from anaconda) and SSD is untouched.

# * 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

# 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.

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
