 woobilicious | Is there any way to validate that my NixOS VPS hasn't got "weird" networking settings issues that might be causing poor throughput? last time I had issues it turned out NixOS ipv6 zeroconfig was misconfigured and would break after a few hours. | 05:11:52 |
| woobilicious | gotta love how my bandwidth halves when I have 2 users streaming: | 05:21:45 |

 kdn | FYI: I've learned with CRS312/routeros only one bridge can be hardware offloaded at a time, so I reconfigured everything for 1 bridge and now I'm getting full speeds | 09:14:24 |

it also explains why the switch was generating significantly more heat recently (had to turn up rack fans)

idk I actually think RouterOS is decent Considering the devices are priced decently, and you get enterprise level configuration, sure, but, and maybe not really mikrotek's fault, but their kernel is really out dated, like lacking fq_codel or fq_cake, and their IPv6 stack last time I checked was buggy on my device. Considering I flawlessly ran IPv6 on a hacked adsl dlink with 8MB of RAM with openwrt like 16 years ago, it's just kinda embarrasing for them. | 05:24:10 |

| zeno | magic_rb: Hello 👋 | 21:33:21 |
 magic_rb | Hey, right so i think the way id debug this is tcpdump it | 21:33:47 |
| zeno | Alright. Gimme a sec | 21:34:09 |
| zeno | Appreciate it, btw! | 21:34:23 |
| magic_rb | Also, sudo tcpdump -i IFACE FILTER -q -w /dev/stdout | wireshark -k -i - think that might work | 21:34:50 |
| magic_rb | I don't recall the exact command but the wireshark portion is correct. You can also run that over ssh, just make sure to exclude the ssh traffic from the capture | 21:35:21 |
| zeno | I did this 👇️
sudo tcpdump -i vlan4 icmp
tcpdump: verbose output suppressed, use -v[v]... for full protocol decode

From my desktop. Below is the result on the desktop:
ping -w 5 192.168.4.100
PING 192.168.4.100 (192.168.4.100) 56(84) bytes of data.

| 21:36:18 |
| magic_rb | Right so blizzard, seems to get the packets but drops them | 21:36:56 |
| zeno | Sure, I'll try 🙂 | 21:37:00 |
| magic_rb | We got enough info | 21:37:08 |
| magic_rb | This to me smells like a firewall problem | 21:37:18 |
