| 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 |
| hexa | * it should only be down if networkd has no match block in a network conifg for it | 00:56:35 |
| hexa | * it should only be down if networkd has no match block in a network config for it | 00:56:41 |
| hexa | I'm not sure BindCarrier is super useful | 00:56:49 |
| hexa | if the four links are down, then the lan link will be down anyway | 00:57:11 |
| kdn | the four links are up | 00:57:25 |
| hexa | yeah, I'm saying the BindCarrier= config is redundant | 00:57:41 |
| kdn | so BindCarriers= is equivalent to the Bond on the other side? | 00:58:50 |
| kdn | * so BindCarriers= is equivalent to the Bond= on the other side? | 00:58:55 |
| kdn | * so BindCarrier= is equivalent to the Bond= on the other side? | 00:59:04 |
| hexa | you don't need an equivalent | 00:59:08 |
| hexa | you define a bond, various interfaces join the bond | 00:59:22 |
| hexa | all that happens in netdevs | 00:59:26 |
| kdn | I don't think I have a netdev for the children interfaces | 00:59:59 |
