How-To

The theme I’m using in Hugo hides list numbers and bullets. Not sure why anyone would ever want that, but that’s why the text after The Solution is indented. If you were to inspect the code, you’d see that it’s actually an ordered list, the numbers are just not visible. So, until I fix the theme…
The “Why”
I used to pay Zoho for their Desk product (I don’t remember what level) that included a custom domain. This was also before my switch to Netlify so my https://support.woostertech.com URL was not going to work. I did have to have Zoho remove my domain entirely since my DNS settings weren’t correct and I could no longer access the portal at all!
What I didn’t want, however, was to have to give customers and clients the entire non-custom URL https://desk.zoho.com/support/woostertech.
The Solution
- Use “Deploy manually” to create a super-simple new site on Netlify; download a landing page demo that is offered as an example. This site will never be seen.
- Unzip the downloaded file to your local computer.
- Add a file named
_redirectsto the root of that unzipped folder. - Add the following line to that file:
https://support.woostertech.com/* https://desk.zoho.com/support/woostertech 301! - Drag-and-drop the entire folder, with the new file, into the Netlify “Deploy manually” page. This will create the page which could be accessed at their special subdomain, but that’s unlikely, and could probably be blocked with some other trickery that I’m not interested in today.
- Add the custom domain under “Domain management.” Netlify will recognize that the domain is already managed by them, so it will be more than happy to manage the subdomain.
That should be all of it. It might take a minute for all of the DNS stuff to update properly and the certificate may need to be renewed to handle the new subdomain, but it should start working. Anytime someone tries to go https://support.woostertech.com, they’ll automatically be redirected.
That should be everything. Unless I think of something else…

Basic Steps
Create Non-Root User and Adjust Permissions
See Initial Server Setup with Ubuntu 22.04
Setup User
adduser karl
usermod -aG sudo karl
ufw app list
ufw allow OpenSSH
ufw enable
ufw status
Test access
SSH Settings
rsync --archive --chown=karl:karl ~/.ssh /home/karl
Setup Docker and Docker Compose
See Install the Compose plugin
Setup Repository
See Install Docker Engine on Ubuntu
sudo apt install ca-certificates curl gnupg
sudo install -m 0755 -d /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
sudo chmod a+r /etc/apt/keyrings/docker.gpg
echo \
"deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
"$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt update
Install Docker Engine
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
sudo docker run hello-world
Install Plugin
Should already be installed with Docker Engine above.
docker compose version

This is just so I can be consistent. Hope this helps!
For some reason, this is harder to find than it should be, so here’s a GoEngineer link and the actual link to the MS page.

Create a persistent TUN
SSH into your NAS
ssh user@local-ip
The following setup steps must be run as root
sudo -i
Write script to /usr/local/etc/rc.d/tun.sh that will setup /dev/net/tun on startup
echo -e '#!/bin/sh -e \ninsmod /lib/modules/tun.ko' > /usr/local/etc/rc.d/tun.sh
Set executable permissions on script
chmod a+x /usr/local/etc/rc.d/tun.sh
Run script once to create a TUN
/usr/local/etc/rc.d/tun.sh
Check for the TUN
ls /dev/net/tun
/dev/net/tun
If you experience trouble getting the TUN to work check out Rui Marinho’s guide
Install docker on your NAS
Package Center -> Search ‘Docker’ -> Install
Set up container
Make directory to store ZeroTier’s identity and config
mkdir /var/lib/zerotier-one
In the next step we bind mount to the host’s /var/lib/zerotier-one created above in order to store ZeroTier’s identity. This is not guaranteed to survive DSM updates. I would suggest placing this on an automatically-mounted volume where your other private user data resides. The location you choose to store your identities should be kept secure and never placed on a shared volume that others can access.
Make Docker container called zt (Repo: zerotier/zerotier-synology)
docker run -d \
--name zt \
--restart=always \
--device=/dev/net/tun \
--net=host \
--cap-add=NET_ADMIN \
--cap-add=SYS_ADMIN \
-v /var/lib/zerotier-one:/var/lib/zerotier-one zerotier/zerotier-synology:latest</pre>
Usage
Previous versions of our package contained a GUI, however this is no longer the case and it is for the better. The CLI can be used as follows:
View node status
docker exec -it zt zerotier-cli status
Join your network
docker exec -it zt zerotier-cli join <network id>
Authorize the NAS on your network. Then view the network status:
docker exec -it zt zerotier-cli listnetworks
Show running container (optional)
docker ps
Enter the container (optional)
docker exec -it zt bash
Upgrading ZeroTier
To upgrade ZeroTier you’ll need to stop and remove the container, then pull latest and start a new container:
docker ps
Example output:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
52c7cb58a1dd zerotier/zerotier-synology:latest "zerotier-one" 5 weeks ago Up 9 days zt
Stop the container
docker stop 52c7cb58a1dd
Remove the container
docker container rm 52c7cb58a1dd
Pull latest updates
docker pull zerotier/zerotier-synology:latest
Now, re-run the commands from the Set up container section.
