TCP and UDP can listen on the same port, DNS is a great example of such. You’d generally need it to be part of the same process as ports are generally bound to the same process

They don’t even need to be the same process. I’m pretty sure that’s just a common practice if something needs both protocols, but there’s nothing stopping you from having a web server on TCP 443 and a VPN server on UDP 443. Ports are an abstraction brought by each protocol, they aren’t in anyway related.

There’s The Serial Port, It’s not really ‘home networks’, but he finds and sets up very early (~80-90s) ISP gear and explains how it works and the history of it. Similar to how Ben Eater uses an ‘old’ 6502 to explain stuff.

I have no idea how CoW interacts with NTFS

With btrfs you can disable COW for specific files, that might give you a little performance boost.

Cloudflare tunnels uses a QUIC connection between the cloudflared on the server and Cloudflare itself, which is encrypted similarly to HTTPS.

Whatever protocol cloudflared uses to talk to your webserver locally is configurable through the Cloudflare access web UI (just change http to https). I’ve actually got it configured to use unix sockets, which lets me treat it differently in my nginx config.

IIRC the RTL chip inside them was originally designed for TV, so it works great! I’m actually using very cheap AliExpress clones for the TV ones, because they otherwise don’t work very well.

I’m also using the outdoor TV antenna on my roof (common in Australia, idk elsewhere), and a splitter and adaptors. And with that I get every channel with no artifacts, at 30% strength, but that’ll probably be higher with not awful SDRs.

I’ve got an interesting setup I’d like to share:

So I’ve got a Raspberry Pi with 4 RTL-SDRs, 2 for TV, 1 for radio, and 1 for plane transponders. That runs SatPi for the 2 TV SDRs, which TVHeadend running on my main server connects to, to record and stream. Jellyfin also connects to TVHeadend to properly index everything and for easy access to recordings and live TV.

Looks like 2x 4 pin fan headers:

But yeah I’ve got an AliExpress X99 board, which threw all sorts of hardware errors, had no fan speed control (100% all the time), no working hwmon sensors, and I ended up buying a used Supermicro board instead.

Will I see any performance increase?

Like others have said LLMs mostly use VRAM, they can use system RAM if you’re running them on CPU, but that’s ridiculously slow.

It will however increase the speed of your compile times, which is especially useful if you’re compiling something large like the Linux kernel on a regular basis.

I’m also worried about not having ECC RAM.

If you are using it purely for LLMs, if it’s going to get bit flips, it’ll happen in VRAM.

If you are compiling large things for customers, I’d recommend ECC, just in case, e.g. you don’t want a bricking firmware from a bit flip. But according to EDAC and my TIG stack, my server’s ECC RAM has never even detected an error in the past year, if I understand EDAC properly, so it’s really not important.

If the HOA’s router supports UPnP/NAT-PMP/PCP then you might be able to use that to get some ports forwarded.

I have also added all Cloudflare IPs in Jellyfin’s known proxies

You should only need to add the IP of the last proxy before reaching Jellyfin, which would be Caddy.

If you can’t get the VPS to work, alternatively there’s Cloudflare but last I checked streaming was a little out of their free terms. With it, you should just have to set your AAAA record and make the cloud orange, that way Cloudflare will proxy it, and IPv4 will work. There’s also Cloudflare tunnels which lets you host websites without port forwarding anything.

I doubt this will be any use, but my Telstra 4G has a public IPv6.

Yeah, I’d avoid the cloud version, but SNMP monitoring on the networked version is nice when you want multiple things to shutdown without relying on a single host.

Cloudflare Tunnels will let you proxy any port, as long as it’s HTTP(S) or SSH, even on free tier.

Also I believe there’s a thing now for proxying other ports anyway on free tier without tunnels, but I haven’t looked too much into it.

if you want to use different SSID for different VLAN

With newer versions of the controller you can actually use PPSK for a different VLAN per password (same SSID), but at the moment you’d be stuck using WPA2.

That’s true, but because of that you can get Cisco certifications, which could be helpful if you end up in an network related job. Those certifications will also give you a lot of knowledge of how networks work. (I’m currently completing a CCNA, and quite enjoy it)

A few other companies also clone the Cisco CLI, so there’s that too. I wouldn’t touch the Web UI if it has one though.

He’s saying you’d probably have more luck finding any simplified photo editor, rather than limiting yourself to just hosted. Something like MS Paint or KolourPaint but I don’t believe they will let you rotate text.

Came across these HP NC522SFP 10Gb NICs

Yeah I have one and they’re pretty good, and I haven’t had an issue using it with generic stuff.

any 10Gb SFP switch

Some switches from bigger companies (like the ones listed on fs.com products) are vendor locked, but you should just need a DAC cable compatible with the switch to work.

a transceiver to get the link from the ISP to the router

Correct! Make sure to get an ethernet/10GBase-T one, because there are other transceivers.

would be easy enough to do some fiber runs there, and it’s all short.

I did forget to mention that you would need more transceivers to convert between the fibre and SFP+, and they are rated for up to different lengths but they should reduce their power for shorter distances. They also come in different speeds too, but unless you’re really strapped for cash, it’s not worth it to go below 10G.

I currently have a 300m ones doing a run of 30m, and I’m about to do a 10m run too. Also these are about AU$10-$20, I find FTLX8571D3BCLs the cheapest, but there are others. (I actually got mine for free off a guy on Reddit)

Also 10G is really cheap if you go with used SFP+ gear. Like I’ve got a managed 48x 1G + 4x 10G Dell switch I got for AU$78 running my network. The NICs are about US$40 used, ConnectX3s seem the cheapest, I usually use Intel X520s which are a little more (watch out for clones though).

For the accessories: DACs are AU$20 new from fs.com, and because you’ll probably need ethernet for that router, a 10GBaseT transceiver is AU$90 new off eBay. Those you could probably buy cheaper used too.

Additionally you wouldn’t be adding 10G to all your devices, I’d just definitely do between your router so you can have 3 1G devices maxing out your 3Gb internet, and maybe add it to a server or two.

And if you do your own runs, in my experience, fibre is slightly cheaper for the longer runs than CAT6 itself too.

No worries! I’d probably prefer bridge mode instead of double NAT, but I guess whatever works for you.
