The #mikrotik replacement switch is now in place. UI took a little time to get used to, but wasn't a huge deal. Fan is audible with the current temperatures in my office but at least it doesn't sound like I'll be picking shrapnel out of the walls any second. Plus, I do have the Noctua fan that a lot of people put into these.

So far, so good. Yes, the #Ubiquiti unified UI across all devices is nice, but I don't play with the configuration of my home network often enough for it to make a massive difference.

TIL about MAC address records in DNS.

I was thinking "man, WoL converting IPs to MACs is unsolvable given ND/ARP cache TTLs and powered-off machines". Guess it's another one we stuff in the garbage can that is DNS 😹

"All Flash" is my new homelab storage (6x 4T) & I'm not sure if it'll still be #FreeBSD.

The goal? Providing storage for clients at home (NFS/CIFS) but also to servers like Proxmox by NVMeoF (TCP).

It's not a ready-to-use NAS and more a MiniPC with 6x NVMe slots and 2x 2.5Gbit and 1x 10Gbit network. So, I'm happy to make the best out of it. Unfortunately, the performance with SPDK is really worse and I'm not yet quite sure why.

Monday #Workout:
220 seconds of plank.
11 minutes of yoga for runners.
20 minutes of strength training.
10.1 KM of #Cycling (16°C, 100% humidity, and 8 KM/H wind)

What an interesting day for me; after the workouts and biking to site, I started off with telehandler training (why not? it's fun!), then some #networking fun, including the most insane ping result I've ever seen, before biking home in the hot (35C humidex) afternoon sun.

Not a bad day. But I would appreciate it to be 20°C cooler. 🫠

I am looking for some kind of VM or system I can run to create a network that I can put an untrusted device on to and allow/deny all its connections one by one - think auditioning a new TV or IOT device rather than out-and-out hostile malware. Assume I will also dump packets for investigation.

Security Onion looks like overkill but I'd like to avoid writing my own firewall rules if possible.

@jpm

Any router is a firewall if you configure it badly enough.

Writing my first meshcore PR 🤘🏿

It's still a work-in progress, but having a lot of fun learning this code base!

https://github.com/ripplebiz/MeshCore/pull/96

#lora #meshcore #meshtastic #privacy #networking #esp32 #offgrid

Wrote a little parser for meshcore packets tonight. It's still messy and a lot more to implement. But, it reads the container format so I'm happy for now.

I have meshcore packets flowing from multiple repeaters(on different frequencies) talking on wifi using udp broadcasts.

The repeaters automatically discover each other on the network and now I'm able to watch their chatter with a quick nodejs server.

Fun fact: I've always mounted my access points on the ceiling or placed them high up on furniture, as the technical specs usually recommend. But today, I decided to try something different: I moved mine and mounted it on the wall.
Surprisingly, the Wi-Fi coverage in the most remote parts of my house has dramatically improved! It just goes to show how fascinating the study of wave propagation truly is.

Out of curiosity: are IPv6 addresses some kind of wild west, unclaimed territory?

When trying to look up who owns some of them that I see in my server logs, I frequently run into "the big void" it seems.

For example: 2200:2242:2064:246::42:6

ipinfo.io says... no ASN, no hostname, no nuffin' available.

Similarly, IP Netblocks says it's part of the range :: - ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff (no shit!😂) and that's all.

Can anyone shed some light on this?

Do I have anyone within my reach who would be willing to help me debug a DNAT issue on OPNsense?

I can sincerely say that it's *probably* trivial, and I am *probably* just missing something obvious; but it's not obvious when you're not quite sure what you're looking for. Reading the documentation, browsing the forum and searching the web has not led me to find a solution.

Boosts appreciated.

For those who specialize in DHCPv6 and systemd: Is there a way to tell the DHCPv6 server "If this IP is available, just give me it, don't give me anything else", or at least get systemd to do that? I'm trying to make an oracle cloud instance running Arch+systemd-networkd that uses DHCPv6 for IP configuration only use one of two IPs assigned to the oracle instance, but leave the other one unused so I can do NDP proxying and route it to my laptop over wireguard, giving my laptop a public IPv6 address as a result, but it appears that oracle is forcing my VPS to use both IPv6 addresses, which is not what I want.
Redacted logs, for context:

Jun 18 06:08:27 somewhere systemd-networkd[-1]: eth0: DHCPv6 address 2000::4201/128 (valid for 1d 5
9min 59s, preferred for 23h 59min 59s)
Jun 18 06:08:27 somewhere systemd-networkd[-1]: eth0: DHCPv6 address 2000::1337/128 (valid for 1d 5
9min 59s, preferred for 23h 59min 59s)

Feel free to boost this for increased visibility if you wish, and if you know of any mailing lists or IRC channels I should ask on, please let me know.
