 matthewcroughan | the .vm attribute of two nixos configs | 19:25:14 |
| matthewcroughan | [root@nixos:~]# ip addr del 10.0.2.15/24 dev eth0
[root@nixos:~]# ip addr add 10.0.2.15/24 dev br0
| 19:25:20 |
| matthewcroughan | Is this what you mean btw? | 19:25:24 |
 Nico | Isn't 10.0.2.15 the virtualbox default nat ip?
You're sure you running qemu? | 19:26:55 |
 casey © | at least for testing, yes. i assume that the ipv6 addresses are working and being natted or something by qemu maybe? | 19:27:04 |
| matthewcroughan | Yeah maybe, the reason I'm doing this in QEMU is to test ofc | 19:27:24 |
| matthewcroughan | 100% it's qemu yes | 19:27:31 |
| Nico | Ok | 19:27:43 |
| Nico | So, since you moved the address, does your ping now work again? | 19:28:01 |
| matthewcroughan | It doesn't no | 19:28:06 |
| matthewcroughan | it's all broken after the br0 exists and has members | 19:28:14 |
| casey © | is ygg finding neighbors via v4 or v6? did you update your default route after moving the ip? | 19:29:00 |
| matthewcroughan | ygg is v6 only | 19:29:13 |
| Nico | On the inside, but what about the outside? | 19:29:27 |
| matthewcroughan | I'm not aware of it doing anything v4 related | 19:29:46 |
| Nico | There are at least public peers with v4 | 19:29:48 |
| Nico | https://publicpeers.neilalexander.dev/ | 19:29:51 |
| matthewcroughan | ah yeah, guess so | 19:29:57 |
| Nico | Ok so can you confirm you have internet access | 19:30:18 |
| matthewcroughan | yeah, all I have is two nixos vms, that you can make yourself by calling nixosSystem with services.yggdrasil.enable | 19:30:42 |
| matthewcroughan | I run the .vm attribute | 19:30:49 |
| matthewcroughan | I then run theip commands from the ifstate webpage | 19:31:04 |
| matthewcroughan | * I then run the ipcommands from the ifstate webpage | 19:31:13 |
| Nico | They vm's are in the same network right? | 19:31:18 |
| matthewcroughan | before br0 it pings fine, afterwards not | 19:31:22 |
| matthewcroughan | they're two separate VMs, but I can't rule out something being funky | 19:31:32 |
| matthewcroughan | yes they're in the same network technically since they're running on the same laptop | 19:31:41 |
| Nico | And the will be for the application you want to use the gretap for right? | 19:31:58 |
| Nico | * And the will be for the application you want to use the gretap for, right? | 19:32:16 |
| matthewcroughan | I don't understand what you're asking? | 19:32:28 |
