| kdn | * nope, not it, this is my config if somebody wanted to take a look while I'm away, linked to the bond definition and configuration variables are at the top of the file:
- I'm renaming interfaces to custom altnames by their permanent MAC address
- I'm forming them all into a bond (by the aliased name)

|  solideva (now @ev4:ev4.me) changed their display name from solideva to solideva (now @ev4:ev4.me). | 18:38:10 |
 adamcstephens | configuring means it's waiting on IP information, no? | 19:58:22 |
| adamcstephens | you could try disabling RequiredForOnline and/or ipv6 | 19:59:20 |
| adamcstephens | * you could try disabling RequiredForOnline and/or ipv6 LinkLocalAddressing | 19:59:56 |
| kdn | isn't LinkLocalAddressing auto-generated? I need it to be online, it'll be the only connection to my LAN | 20:18:48 |
| kdn | * isn't LinkLocalAddressing auto-generated locally? I need it to be online, it'll be the only connection to my LAN | 20:19:01 |
| kdn | oh. unless LLA requires some forwarding on switches? | 20:19:13 |
| adamcstephens | no. maybe i'm misreading this config generation. | 20:28:35 |
| adamcstephens | maybe it would be easier if you shared a generated network unit file | 20:31:30 |
| adamcstephens | and the networkctl status output | 20:31:46 |
 hexa | Redacted or Malformed Event | 23:17:23 |

linkConfig.RequiredForOnline = "carrier";

| hexa | any .network file for the bond interface? | 00:50:32 |
| hexa | ah, the bond interface is lan | 00:51:00 |
| hexa | so no vlans on top or anything | 00:51:12 |
| hexa | DHCP=true means DHCPv4 and DHCPv6 | 00:51:30 |
| hexa | you likely only want DHCP=ipv4 | 00:51:53 |
| hexa |
LinkLocalAddressing=ipv6
is probably redundant
| 00:52:12 |
| hexa | because networkd will not generally set up "link-local" IPv4 addresses (APIPA) | 00:52:40 |
| kdn | riight, I don't have DHCPv6 server set up yet on the lan | 00:53:43 |
| hexa | and you probably don't want or need one | 00:53:58 |
| kdn | shouldn't I still get a DHCPv4 lease even if the DHCPv4 failed? | 00:55:25 |
| kdn | what I'm seeing right now that lan interface is simply down | 00:55:34 |
| kdn | * shouldn't I still get a DHCPv4 lease even if the DHCPv6 failed? | 00:55:54 |
| hexa | it should only be down if networkd has no match block for it | 00:56:27 |
