 zeno | Hmmm... | 21:37:28 |
| zeno | I am running a Unifi UDM SE | 21:37:36 |
 magic_rb | NixOS by default logs dropped packets in dmesg, check dmesg | 21:37:39 |

I am running a Unifi UDM SE The what now, i dont use corporate bullshit so my knowledge is limited | 21:37:52 |
| zeno | Do you have the full command? We're beyond my knowledge here 😅 | 21:38:28 |
| magic_rb | sudo dmesg might say dropped packets | 21:38:44 |

| zeno | Does it start off easy? Networking is not my strong suit, even though it is really fun | 21:41:23 |
| zeno | Hmmm... this is what the latter portion of sudo dmesg tells:

| zeno | I don't actually have any devices with that MAC address among the devices connected to my switch | 21:46:53 |
| zeno | I mean, I can read it but not understand it 😂 | 21:47:18 |
| magic_rb | oh its cni0 sorry | 21:47:37 |
| magic_rb | thought it was eth0 | 21:47:42 |

| magic_rb | can you rerun this with -n for numeric? the hostnames are astoundingly useless in debugging this | 21:52:06 |
| zeno | tcpdump? | 21:54:04 |
| zeno | or ping? | 21:54:14 |
| zeno | Because tcpdump does not seem to have that flag? | 21:54:46 |
