  • Borg / k8s / Docker are not the same thing. Borg is the predecessor of k8s, a serious tool for running production software. Docker is the predecessor of Podman. They all use containers, but Borg / k8s manage complete software deployments (usually featuring processes running in containers) while Docker / Podman only run containers. Docker / Podman are better for development or small temporary deployments. Docker is a company that has moved features from their free software into paid software. Podman is run by RedHat.

    There are a lot of publicly available container images out there, and most of them are poorly constructed, obsolete, unreprodicible, unverifiable, vulnerable software, uploaded by some random stranger who at one point wanted to host something.


  • VLANs are lower than IP so you don’t need a router to have a VLAN, but you will need a router to get packets between the networks. I don’t think a WiFi repeater works. You likely need separate WiFi client and AP devices so you can put your WiFi on a different channel. Otherwise you’re probably halving your WiFi performance when connecting to the other network over the same airwaves.

    Unless you can convince the other network to route your IP addresses, this setup will give you another layer of NAT and may cause problems with online games.








  • Having a non-garbage domain provider can be a luxury. I used to work at a place where we were paying boatloads of money for certificates from Sectigo for internal services, and they were charging us extra per additional name and even more if we wanted a wildcard, even though it didn’t cost them anything to include those options. Getting IT to set up the DNS records for Let’s Encrypt DNS verification was never going to happen.



  • A large percentage of those hosts with SSH enabled are cloud machines because it’s standard for cloud machines to be only accessible by SSH by default. I’ve never seen a serious security guide that says to set up a VPN and move SSH behind the VPN, although some cloud instances are inherently like this because they’re on a virtual private network managed by the hosting provider for other reasons.

    SSH is much simpler and more universal than a VPN. You can often use SSH port forwarding to access services without configuring a VPN. Recommending everyone to set up a VPN for everything makes networking and remote access much more complicated for new users.


  • Shodan reports that 35,780,216 hosts have SSH exposed to the internet.

    Moving SSH to ports other than 22 is not security. The bots trying port 22 on random addresses with random passwords don’t have a chance of getting in unless you’re using password authentication with weak passwords or your SSH is very old.

    SSH security updates are very infrequent and it takes practically no effort to keep SSH up to date. If you’re using a stable distribution, just enable automatic security updates.
