[2838.78 --> 2846.26] I'd love to have a custom model that could detect our two vehicles versus, say, a DoorDash delivery vehicle or a UPS truck. |
[2847.00 --> 2849.24] Wow, that's a great idea. |
[2849.70 --> 2850.94] Have you seen anything about that? |
[2851.24 --> 2853.38] I wonder if that's possible right now. |
[2853.98 --> 2856.48] Well, we might have something in this space. |
[2856.48 --> 2865.84] We're planning fairly soon a site reliability engineers only live stream with Chris and I to hang out with the supporters and patrons of the show. |
[2866.40 --> 2871.62] And I've been doing some background sleuthing with the author of an app called Double Take. |
[2872.10 --> 2876.88] And essentially what this does is it's facial recognition for Home Assistant. |
[2876.88 --> 2881.08] So it will sort of plug into DeepStack and Frigate and Double Take. |
[2881.18 --> 2889.66] It's all this kind of machine object detection learning type melange of stuff that all sort of kind of works together. |
[2890.02 --> 2894.62] I could see adding a vehicle detection model in one of these programs being quite viable. |
[2894.74 --> 2898.50] And perhaps we'll pick the Double Take author's brain on that on that live stream. |
[2898.50 --> 2898.94] Interesting. |
[2900.48 --> 2901.38] I look forward to that. |
[2901.38 --> 2908.22] I could see, like, the next thing I might want, right, is detecting Levi versus any other animal. |
[2908.76 --> 2909.92] Don't worry about Levi. |
[2910.18 --> 2911.98] Dog, not hot dog, right? |
[2912.28 --> 2912.72] Right. |
[2914.06 --> 2914.70] All right. |
[2915.10 --> 2916.62] This will probably be our last one today. |
[2916.74 --> 2918.98] IA writes in with some network jargon questions. |
[2919.16 --> 2919.44] He says, |
[2919.44 --> 2923.82] I recently graduated and discovered this podcast a few days ago. |
[2923.98 --> 2932.34] So since I've been listening, I've heard the term doubly natted and the term punching a hole through a firewall on the podcast at least a couple of times. |
[2932.56 --> 2934.54] I think TeamViewer was cited as an example. |
[2934.76 --> 2937.98] I'm wondering if you could explain what this is in a bit of detail. |
[2938.38 --> 2942.50] I'd like to know about ways to overcome DoubleNet and the pros and cons of that. |
[2942.68 --> 2944.52] You mentioned Wireguards and VPNs. |
[2944.80 --> 2945.88] Maybe they fit into this picture. |
[2946.14 --> 2946.48] Thanks. |
[2946.48 --> 2950.92] Well, Mr. Carrier Grade, Nat, why don't you start by explaining that one? |
[2951.12 --> 2952.84] I thought you were giving me a hard time. |
[2953.36 --> 2953.78] Right. |
[2954.08 --> 2963.98] So what has just unfortunately become way more common than we'd like is a situation where you have somebody that runs a private network. |
[2964.44 --> 2969.68] So a private network is generally a way of saying a network that doesn't route outside itself. |
[2970.34 --> 2972.96] So if you're on that network, you're not routing. |
[2973.32 --> 2974.48] You're not publicly available. |
[2974.64 --> 2976.10] People can't find you on the internet. |
[2976.10 --> 2977.26] You're a private network. |
[2977.26 --> 2982.66] The most typical example of that would be, say, like an intranet at a school or even just your LAN at home. |
[2983.26 --> 2983.44] Right. |
[2983.56 --> 2985.12] Those are all private networks. |
[2985.12 --> 2992.34] Now imagine that private network set up a network for another set of machines. |
[2992.34 --> 2994.78] And it was essentially networkception. |
[2995.48 --> 2997.62] And it was also a private network. |
[2997.78 --> 3002.86] So you have a private network that is connected to a private network that is then connected to the public internet. |
[3002.86 --> 3011.24] And that, in a really loose way, is what double-nated is, is you were behind two network address translated networks. |
[3011.24 --> 3015.54] You can actually set this up for yourself if you're curious to kind of play around with it. |
[3016.02 --> 3020.44] Spin up OpenSense or PFSense in a VM behind your existing router. |
[3021.14 --> 3025.66] And that would create a network within a network, which is essentially what Chris is talking about here. |
[3025.66 --> 3030.32] So he has a wireless ISP that's, you know, got a mast up on a hill somewhere. |
[3030.54 --> 3033.18] And that thing has a router behind it. |
[3033.50 --> 3036.84] So that router has a public-facing IP address. |
[3037.18 --> 3041.26] Now you know that there are only a certain number of IPv4 addresses available. |
[3041.80 --> 3044.80] They're expensive as a consequence, relatively speaking. |
[3044.80 --> 3048.82] And so what a lot of these wireless ISP guys do is to save a bit of money. |
[3049.60 --> 3059.66] They will just give you a private IP and essentially translate your local devices on your local network in Chris's RV, for example. |
[3060.78 --> 3065.14] They won't know, you know, everything he's got behind their little router that they've given him. |
[3065.68 --> 3070.72] But his router will have an IP address on their network, not the public internet. |
[3070.72 --> 3070.90] Yeah. |
[3071.36 --> 3081.22] And because of this, software like VPNs or other types of software that want to, quote unquote, punch a hole through a firewall, |
[3081.52 --> 3086.96] they can't just open up a port on the firewall through something like Universal Plug and Play and start receiving connections. |
[3086.96 --> 3095.00] Because even if they open up a port on that firewall, there's just a private network on the other side of that that can't talk to the internet. |
[3095.00 --> 3105.34] And so when you're double-natted, you need something that is sort of like a proxy between whatever is on the private network and whatever is on the public network. |
[3105.64 --> 3109.64] And that's usually what you hear us talking about ways around double-natting or something like that. |
[3109.64 --> 3117.20] And really what it just means is that if you want to host something on a double-natted network, you're going to have to work to make it happen. |
[3117.32 --> 3119.80] And it's not going to be the most efficient way to do it. |
[3120.46 --> 3128.88] And they probably don't want you doing it because another place you'll often see this is on cell networks and mobile networks and some satellite internet. |
[3129.28 --> 3132.86] And so they probably don't want you hosting anything either. |
[3132.98 --> 3133.66] That's very common. |
[3133.72 --> 3137.16] And that's where something like our sponsor, Linode, could be useful. |
[3137.16 --> 3150.24] Yeah, and this is one of the reasons why I found Tailscale so useful is they host a lighthouse, a third-party kind of witness node somewhere that does all that natraversal stuff for you. |
[3150.58 --> 3154.20] So then you end up with a peer-to-peer connection to the remote host. |
[3154.32 --> 3163.52] And I'm very pleased to say that I've been using Tailscale now for, what, a couple of months and doing all my backups to England on my Synology box over Tailscale. |
[3163.80 --> 3165.50] And it's just working. |
[3165.50 --> 3167.12] I really like it too. |
[3167.16 --> 3167.40] Yeah. |
[3167.78 --> 3169.40] Higher phrase you cannot find. |
[3169.50 --> 3170.18] It just works. |
[3170.48 --> 3174.40] It is so simple to get up and get going and have a mesh network. |
[3175.24 --> 3184.80] The only thing about Tailscale that I'm not a huge fan of is you are placing a lot of trust in them because they are doing the key exchange and managing all of that stuff for you. |
[3184.80 --> 3194.56] And if you want something like Tailscale but you want full control and you want to be completely trustworthy setup, I still think Nebula is better in that regard. |
[3194.56 --> 3199.38] Especially in a server-to-server-to-server scenario, I might be more comfortable with Nebula. |
[3199.74 --> 3203.54] But if it's like phone workstation server, that might be where I are. |
[3203.80 --> 3206.44] Or workstation, workstation, workstation among friends. |
[3206.60 --> 3207.68] I'd probably go Tailscale. |
[3207.68 --> 3212.90] But when it's server-server-server, I might be more inclined to go Nebula just because you have complete control. |
[3213.10 --> 3217.00] It is also exceedingly good at punching through double nat. |
[3217.46 --> 3221.32] And you have complete control over the keys in that scenario. |
[3221.32 --> 3223.48] You know what I'd equate that to? |
[3223.84 --> 3225.36] Tailscale is a bit like Plex. |
[3225.78 --> 3231.08] Like I'm not totally 100% on board with what they're doing, but it's very slick. |
[3231.66 --> 3233.26] And Nebula is kind of like Cody. |
[3233.68 --> 3234.16] Jellyfin. |
[3234.48 --> 3235.06] Nice, Jellyfin. |
[3235.06 --> 3235.64] Or Jellyfin. |
[3235.88 --> 3236.84] Jellyfin, you know what? |
[3236.88 --> 3242.04] I didn't say it during the compute module review, or at least first look. |
[3242.72 --> 3247.48] But Jellyfin, in a way, is a lot more appealing now. |
[3247.48 --> 3251.78] Because, you know, Plex has added a lot of stuff, and Jellyfin remains kind of lean and mean. |
