(Also the limitations in internet search in the year of our lord 2025: I can find answers for solving issues in specific one-to-one connections within this network, but they leave out other crucial components such that I can't get the whole thing going all at the same time.) So I am here, appealing to you, to help me think this through.</p> +<p>I have AT&amp;T fiber coming into my house, with a BGW320 modem/router combo. I have a 3-device Eero mesh wifi network, with the gateway Eero connected to the BGW320 via ethernet. I have a Synology NAS connected to the Eero gateway via ethernet, and I'm soon going to have a mini server that... will get connected to all of this somehow that I haven't yet figured out.</p> +<p>I have turned off the wifi radios on the BGW320, so that I only have the wifi network provided by the Eeros. Right now, I have IP Passthrough turned on on the BGW320, set to DHCPS-dynamic; the WAN IP address is being picked up properly by the gateway Eero and the WAN type on the Eero is set to DHCP (Default). The bajillion devices in my house are being doled out IP addresses appropriately vis DHCP, including the NAS, and are for the most part getting good bandwidth (though the gateway Eero seems to have to reconnect to the internet periodically, so there's clearly some setting in the BGW320 that needs futzing with already).</p> +<p>But here's where things start to get complicated: I have purchased a block of 5 static IP addresses from AT&amp;T (really 8, but one gets assigned to the router and 2 are unusable), with the intent of assigning the NAS and the forthcoming server a static IP. So in the BGW320 admin interface, I have both a private LAN subnet and DHCP range (of the <a href="http://192.168.1.XXX">192.168.1.XXX</a> variety) and a public subnet that includes my public gateway address, my public subnet mask, and the 5-address DHCP range.</p> +<p>In passthrough mode, the BGW320 just hands off all DHCP stuff to the Eero mesh, which has the gateway address of 192.168.4.1 (the Eero default). In the Eero admin interface, I can use Reservations &amp; port forwarding to assign a static IP address to a device, like the NAS. However, my static IP addresses are outside the Eero's subnet range, so it won't accept them.</p> +<p>On the NAS, I can use the admin interface to assign the static IP address right there, and it will accept the address, but doing so breaks a bunch of connections between the NAS and the outside world, like Synology's software updaters, whose IP addresses it cannot resolve. I am guessing that this is because assigning the static IP on the device breaks the DNS connection, but it's also possible that it's got something to do with the way I've set up the NAS's firewall rules, which, ugh.</p> +<p>Anyhow, I am wondering at this point whether going with IP Passthrough on the BGW320 is at the root of the problem. If instead I let the AT&amp;T device handle all the WAN/DHCP stuff, and put the Eeros into bridge mode, will the static IP addresses become assignable to devices via the BGW320? If so, will devices connected to the private subnet via the Eeros still be able to talk to the devices on the public subnet?

It's good to see foregrounded the idea that preservation is not a matter of technological development (quite the contrary) but of human care buttressed by financial investment. I found myself particularly struck by this:</p> -<blockquote> -<p>The advantage of print is that it can be a practice. What was printed before can be reprinted. The downside is that, in order to take advantage of the full preservational powers of the codex form, what you are saving and printing has to be valued by the public.</p> -</blockquote> -<p>In the digital realm, of course, we've long heard that Lots of Copies Keep Stuff Safe -- and it's true -- but we still have to care enough to make those copies, and to ensure that they're properly stored and checked and migrated as needed. Perhaps the public might be enlisted in preservation efforts by being <em>encouraged</em> to make copies of cultural objects they value rather than by being <em>punished</em> for doing so. As Neely-Cohen notes, &quot;The most enduring decentralized [preservation] efforts don’t owe their success to technological or organizational innovation, but rather by having enlisted generations of people with an emotional and intellectual investment in their worth.&quot;</p> -<p>The scale of the digital preservation problem is going to require massive investment, and the political will necessary to generate it -- a requirement easily generative of despair here at the end of 2024. But here we are, with stuff we care about and want to keep safe.</p> -<blockquote> -<p>[I]f you, an individual reading this, want to store something and ensure it survives a century, what should you do? More than one thing. You should combine every method available to you, layers of backups, armies of copies, and most of all, practices and sites that encourage a culture of watchfulness and care. You should fight for a society that values the sciences and arts and that which they produce. And then, each day, you should do whatever it takes to keep your something safe, do whatever you can to empower the next generation to do the same, and then entrust that battle to them, to repeat into futurity.</p> -</blockquote> \ No newline at end of file diff --git a/feed/masto.xml b/feed/masto.xml index d9a233821a..cac4ab9e8a 100644 --- a/feed/masto.xml +++ b/feed/masto.xml @@ -545,13 +545,21 @@ pre[class*="language-diff-"] { The long-running and erratically updated blog of Kathleen Fitzpatrick. - 2025-04-20T14:56:45Z + 2025-05-11T12:39:42Z https://kfitz.info/ Kathleen Fitzpatrick kfitz@kfitz.info + + Networking + + 2025-05-11T12:39:42Z + https://kfitz.info/networking/ + This post is going to put my full nerdiness and my full cluelessness simultaneously on display, but I am building a home network that is going to include a server hosting much of my online presence, and I am running into some issues that are... + + Gitea diff --git a/gitea/index.html b/gitea/index.html index e9b20e008b..8f082532e2 100644 --- a/gitea/index.html +++ b/gitea/index.html @@ -676,7 +676,7 @@ hr.new {

It's super zippy and very lightweight, and has allowed me to migrate my repositories from GitHub quite seamlessly. And there's lots of room to grow, resource-wise, so if those friends decide they want to test things out I can invite them to join me.
