 Cadair | so why is tcpdump seeing responses, but ping is not seeing them? | 14:47:31 |
 Ramses 🇵🇸 | your firewall might be intercepting them | 14:57:59 |
| Ramses 🇵🇸 | or things like the kernel reverse path filter | 14:58:27 |
| Ramses 🇵🇸 | have a look at the firewall, and if you can't find a potential issue, you can insert log statements in the firewall to figure out at which point the packets are being dropped (and if they reach the firewall in the first place) | 15:00:46 |
| Cadair | oh it was the firewall | 15:37:12 |
| Cadair | thanks | 15:37:13 |
| Cadair | it's working | 15:37:15 |
| Cadair | I can recieve email again | 15:37:19 |
| Cadair | This finally motivated me to migrate to networkd on my router, so it's achieved something lol | 15:39:10 |

 Andy Hamon | I stumbled upon https://docs.dent.dev/ and their hardware table: https://dent.dev/ecosystem/hardware-compatibility/
the "48x1G PoE + 4x10G SFP" Delta switch mentioned is a Delta TN48M-P
Claude seemed to think that most of the hardware support is fully upstreamed in the linux kernel.
Bought one, and i got stock aarch64 nixos booting cleanly, linux kernel 7! And the prestera driver loads, all switch ports appear in ip link. All i had to was build a device tree for it (which claude made short work of, based on the device tree from the dentos project).
I am super pelases, as my mikrotik poe switch is one of the only things in my network rack that doesn't run nixos.
| 01:12:38 |
| Andy Hamon | Anyways, thought I'd share here, in case there are others who have been on the prowl for a network switch that can run nixos. | 01:13:30 |

| Andy Hamon | oh and the non-poe version i can confirm is actually pretty quiet. poe one hasn't arrived yet. (yes i bought two lol) | 01:20:13 |
| Andy Hamon | * oh and the non-poe version i can confirm is actually pretty quiet even before any fan mods. poe one hasn't arrived yet. (yes i bought two lol) | 01:21:18 |
 hexa | they do sound like they eat energy for free | 01:41:41 |
| hexa | anyway, 48x1G is not really interesting in 2026 | 01:42:22 |
| hexa | recently played with https://novalinktrade.com/wp-content/uploads/2024/07/SKS8300-12E2T2X.pdf | 01:43:32 |
| hexa | but with openwrt | 01:43:36 |
| hexa | 12x2.5 Gbps, 4x10Gbps (2 Copper, 2 SFP+) | 01:43:59 |
| hexa | but sadly no PoE | 01:44:02 |
| Andy Hamon | PoE is the main reason it is interesting me. If you remove PoE as a restriction then I agree there are more interesting options | 01:46:58 |
| Andy Hamon | * PoE is the main reason it is interesting me. If you remove PoE as a constraint then I agree there are more interesting options | 01:47:05 |
| hexa | yeah, but even with PoE I'd want ports with more than 1G ideally | 01:47:23 |
