Cake day: June 10th, 2023

  • My Linux laptop is set to check for updates daily, which I then apply manually when I notice the tray icon. I sometimes procrastinate when it comes to reboots though.

    My Android phone is on auto-update, which seems to mean whenever it’s being charging for a few hours (so typically when charging overnight). Because the battery is still pretty good and I don’t need to charge daily, that comes down to once every 2-3 nights or so.

    My personal Linux servers (which run my self-hosted apps) are configured to automatically apply all updates (and reboot if necessary afterwards) at the time of day I’m most likely to be awake and available to manually fix stuff if anything goes wrong. The Docker-containers that run on them mostly get auto-updated to the latest version every 6 hours by Watchtower. A few containers have more cautious policies though, ranging from pinning a major version (but auto-upgrading to new minor versions within that) to pinning a specific version and at most sending a notification if there’s an update. The latter is limited to stuff that has broken before and/or where newer releases are known to be buggy or incompatible.

    When it comes to major updates (i.e. new distro releases) of my Linux machines, I typically wait about a month before upgrading because I’ve been bitten by release-day bugs before.



  • You don’t actually have to set all the modification dates to now, you can pick any other timestamp you want. So to preserve the order of the files, you could just have the script sort the list of files by date, then update the modification date of the oldest file to some fixed time ago, the second-oldest to a bit later, and so on.

    You could even exclude recently-edited files because the real modification dates are probably more relevant for those. For example, if you only process files older than 3 months, and update those starting from "6 months old"1, that just leaves remembering to run that script at least once a year or so. Just pick a date and put a recurring reminder in your calendar.

    1: I picked 6 months there to leave some slack, in case you procrastinate your next run or it’s otherwise delayed because you’re out sick or on vacation or something.



  • Any chance you’ve defined the new networks as “internal”? (using docker network create --internal on the CLI or internal: true in your docker-compose.yaml).

    Because the symptoms you’re describing (no connectivity to stuff outside the new network, including the wider Internet) sound exactly like you did, but didn’t realize what that option does…


  • It also means that ALL traffic incoming on a specific port of that VPS can only go to exactly ONE private wireguard peer. You could avoid both of these issues by having the reverse proxy on the VPS (which is why cloudflare works the way it does), but I prefer my https endpoint to be on my own trusted hardware.

    For TLS-based protocols like HTTPS you can run a reverse proxy on the VPS that only looks at the SNI (server name indication) which does not require the private key to be present on the VPS. That way you can run all your HTTPS endpoints on the same port without issue even if the backend server depends on the host name.

    This StackOverflow thread shows how to set that up for a few different reverse proxies.






  • If this is something you run into often, it’s likely still only for a limited number of servers? ssh and scp both respect .ssh/config, and I suspect (but haven’t tested) that sftp does too. If you add something like this to that file:

    Host host1 host2
      Port 8080
    

    then SSH connections to hosts named in that first line will use port 8080 by default and you can leave off the -p/-P when contacting those hosts. You can add multiple such sections if you have other hosts that require different ports, of course.







  • In fact, unless you post your domain somewhere online or its registration is available somewhere, it’s unlikely anyone will ever visit your server without a direct link provided by you or someone else who knows it.

    If you use HTTPS with a publicly-trusted certificate (such as via Let’s Encrypt), the host names in the certificate will be published in certificate transparency logs. So at least the “main” domain will be known, as well as any subdomains you don’t hide by using wildcards.

    I’m not sure whether anyone uses those as a list of sites to automatically visit, but I certainly would not count on nobody doing so.

    That just gives them the domain name though, so URLS with long randomly-generated paths should still be safe.
