  • No DNS on Proxmox machine

    I had some more network weirdness setting up this new Proxmox machine. When I went to run the updates it couldn’t resolve any of the addresses: So some sort of DNS problem. The entry for the DNS is in /etc/resolv.conf when I looked in there, it said: Well, that does not seem great. I feel…

  • Proxmox Dynamic IP

    I ran into a little hiccup today. I’m building out a Jellyfin media server in a little HP G2 Mini PC. The config was going to be a Debian server inside Proxmox (because I love VM snapshots for backups) running Jellyfin in a container. There’ll be an external USB3 hard drive for the media storage.…

  • NAS Storage Calculations

    I’ve been really happy with my two bay Synology NAS – a DS216j. The Synology’s seem to have great reputation for just pushing on. Mine is loaded up with two 8TB Seagate Barracudas in RAID 1 leaving me with a one drive failure redundancy. I guess a more hard-core host-er than me would be building…

  • Recursive list of files in Linux

    I’ve spent a few hours over the weekend migrating a media library from an external USB drive to the NAS, and in the process reorganised it, and in many cases bulk changed file names. I’ve also added a heap of metadata. I’d like to check that I haven’t missed any files, but a side by…

  • Sudoers’ file not working

    A couple of weeks ago, I posted about the sudoers’ file, and how there was a special tool for editing it since breaking it is a bad idea, and that in fact I needn’t bother, since I can just add my user to the sudoers’ group with: That worked (on Unbuntu) since /etc/sudoers contained a…

  • Folder ownership problems with Jellyfin

    After being so blase about the file permissions when mounting the share to the Linux file system, and testing that root could read and write to the share, I ran into problems immediately when trying to add the media folder as a library in Jellyfin – getting the error “The path could not be found.…

  • Accessing a Synology NAS from Linux

    I picked up a Synology DS216j NAS from eBay to use for storage for the rapidly growing home lab. The eventual plan is that as well as my VM backups, it will host the media library, and eventually (when this has all proved itself reasonably bullet-proof) my current DropBox contents. That won’t all fit on…

  • Configuring Proxmox for Free Use

    I installed Proxmox on my second server last night, and tonight when I ran apt update I ran into the error you get when you haven’t bought a license. Even though I guess it was only a month ago (let that sink in people who think the raspberry Pi they just bought is going to…

  • Moving a VM between two Proxmox hosts

    So, the very small datacentre has undergone a major hardware upgrade today. The HP 800 G1 is joined by an HP 800 G2. Four core i7 vs the old two core i5. Double the RAM to 16GB, four times the disk. The old machine will become a dev/play machine – still virtualised, and the new…

  • Uptime Kuma & NFTY

    Uptime Kuma is a monitoring tool suitable for self-hosting, and as well as being a good tool for monitoring the status of your network and applications, it’s a nice smallish app to get started on Docker containers. Since it’s in a container, you need to create a volume for it and pass it in to…
