SSL Cert

https://certbot.eff.org/lets-encrypt/debianother-nginx.html

This worked. For renewing the cert automatically, I used this in crontab:

23 0,12 * * * ./opt/certbot/certbot-auto renew --nginx

raspberry pi auto mount usb drive

my drive is hfsplus usb 2TB

get the usb UUID from blkid

pretty print drive locations lsblk -o NAME,FSTYPE,SIZE,MOUNTPOINT,LABEL

followed this, with special attention to the order. Drive must be unmounted before running fsck.

Installing Emby on a Raspberry Pi 3

note: this is probably not a good idea if any of the media need transcoding.

another note: was able to install the open source verion of Emby called JellyFin, using Docker: https://hub.docker.com/r/jellyfin/jellyfin

dependencies

https://www.mono-project.com/download/stable/#download-lin-debian

sudo apt install apt-transport-https dirmngr

Foward requests to one port to another on the same server

I wanted to forward requests comming to a server on port 2222 to the same server port 22.

I'm using ufw for the firewall on the server.

1. allow port 22 and 2222 on the server.

$ sudo ufw allow 22

Local DNS dnsmasq

Use case

I wanted to have an outside domain name resolve to a computer inside my local private network. I am tyring out duckdns.org to handle the resolution. The DNS resolves fine outside of my local network, yet locally the fqdn will not resolve. To enable this, a local dns needs to handle the request, routing to the local server.

This is where the raspberry pi dns comes in. I'm running Raspbian GNU/Linux 9 (stretch), a Debian variant. http://www.raspbian.org/

NOTE

I have been unable to get dnsmasq to start correctly on reboot. Nothing stands out in daemon.log. sudo service dnsmasq status shows one particular line that is different from the status of a reboot vs a manual service restart:
