Fluent-bit rocks

A short survey of log collection options and why you picked the wrong one. 😜

Who am I? Where am I from?

I'm Steve Coffman and I work at Ithaka. We do JStor (academic journals) and other stuff. How big is it?

Export TOTP tokens from Authy

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

Docker Registry with Minio storage example

Running a docker registry with Minio S3 backend

Use docker logs to retrieve access key and secret key from minio container

docker logs minio

Create config.yml for Docker Registry

This file will have to be mounted to /etc/docker/registry/config.yml

# $LOCAL_IP: 'localhost' or machine from local network
# $LOCAL_PORT: open port on local machine
# $REMOTE_IP: remote localhost or IP from remote network
# $REMOTE_PORT: open port on remote site

# Forward Tunnel: map port from remote machine/network on local machine
ssh -L $LOCAL_PORT:$REMOTE_IP:$REMOTE_PORT $USER@$SERVER

# Reverse Tunnel: make local port accessable to remote machine
