That’s not how that works. network_mode: host shares the network namespace with the container host, so it doesn’t do any NAT, it only exists on the host’s IP. It would be akin to running a natively installed app, rather than in a container. macvlan networking is what gives a container its own IP on the logical network, without the layer of NAT that the default bridge mode networking that docker typically does.

I would love to if I had them! Haha. I’m working on the dashboard right now, which will be part two.

I don’t have a great answer on the IOPS requirement, but I imagine it’s less than something based on elasticsearch/open search based on the reindexing. I’ll try and benchmark it if possible.

Great question, I’ve asked myself the same thing.

First, in my opinion they serve to achieve different things. While openwrt is a firewall, it’d a simple zone based firewall and it designed primarily as router firmware, not firewall software.

Opnsense is BSD based, openwrt is Linux based. Those both haves pros and cons. BSD has serious pedigree in the networking world. Juniper switches are still based on BSD even. Openwrt gets the Linux traffic shaping goodies like cake though.

I chose openwrt because it’s more suited to my environment, where I have 10 VLANs, a 10G fiber core, and want IDS/IPS. Openwrt is meant to be lighter weight, but is less feature-full.

Isn’t it the best? Somehow all the big log and aggregation stacks are java… Elk, graylog, wazuh…

🤘

Certainly! Feel free to comment on any hardships, if I notice a glaring omission or something I’m happy to fix it. This is also a pretty new setup for me, so I’m still tweaking and working through what will become part 2 here in Grafana, currently.

Hey, the journey is the destination sometimes. Glad you liked it!

There’s no mobile app, but the web app front end is a PWA, so you can select “install” from the page in a WebKit browser and get what is effectively a mobile app.

Awesome! Thanks for the banter. It’s easy to get stuck in your own echo chamber working IT every day, so it’s nice to have these kinds of questions. Feel free to drop anything into comments too, maybe other readers will benefit too!

No worries, and I’ll accept criticism too, that’s how you improve.

Anyway, this is effectively giving you tailscale, a remote access mesh VPN solution, but with total control and ownership of the control plane server, instead of relying on the opaque tailscale owned and controlled infra. I touched on it briefly again the ‘DERP Config’ section of part 2: https://roguesecurity.dev/blog/headscale-quadlet-part2#DERP Config

No, it’s not you, the XML file isn’t including post content yet. I wasn’t sure how to do that, so figured I’d start with the simple thing of generating a list from the posts manifest for the time being. This would at least show you a link for when a new post is up, but you’re right there’s no content yet. When I have a bit more time I’ll research how can I dynamically add the entire post content.

Realized I didn’t answer the last question here on hardening. The answer is sure! I don’t have much planned for the blog, as I was just thinking I’d take “public notes” for my tinkerings as they came. I’ve done linux administration for a long time though so I’d be happy to put together a post on baselines and hardening

Great question. I tried to very briefly touch on it in the post. The bottom line is that its benefits are there mostly for rootless podman, which I’ve chosen not to implement here (yet). You can also configure it so that the socket is always active and that will then trigger the service associated with it, so that you save on resources when the service isn’t needed. However, I didn’t want to do that as it would likely increase page load time for readers.

Okay, rudimentary RSS feed added! It’s available in the navbar, and autodiscovery with your RSS aggregator should work from any page. Let me know if you have issues.

No, and that’s a deficiency. Thank you for asking. I totally had this on the roadmap but let it slip. I’ll work on finalizing that right now. Much appreciated!

The other poster here is correct, this is just an account of my journey through self hosting traefik, and ultimately headscale, without the hurdles along the way. I tried to include a few links to unclear terms along the way in the narrative, maybe those would help you figure things out. Unfortunately I can’t write for an audience of everyone, but hopefully you can still gain some value or learn some new things! Thank you for the feedback.

Ah yes, those examples were helpful and definitely helped inspire this. Glad you found some value in the ramblings. Post 2 will be up soon.

What nice feedback to read. I think you and I are aligned in what this will hopefully become. I really just wanted to start publicly sharing my hobby notes instead of holing them up in a local Joplin file or something, so that’s what I’m going to do. We may have similar hobbies though, which sounds like it’ll benefit you. Haha.
