| CsokiCraft | Hi! I have an /e/n/i file which has IP aliases defined in it (interfaces in the form of `eth0:1`, for instance). `netplan migrate` seems to generate separate `ethernets` from it with colons in the name, which makes NM throw up... Is there any way to make `netplan migrate` handle these (add separate `addresses` instead), or is it not supported? Or | 10:02 |
|---|---|---|
| CsokiCraft | maybe it is, and we just have a too old netplan version? | 10:02 |
| danilogondolfo | Hi, yeah netplan doesn't support interface aliases. You need to add multiple IPs to the same interface. And I'm afraid "netplan migrate" is kinda experimental... | 10:09 |
| CsokiCraft | Is it possible to add multiple IPs to one interface in /e/n/i? | 10:26 |
| CsokiCraft | The problem is we have to incrementally update our fleet from ifupdown2 to netplan/NM... | 10:28 |
| danilogondolfo | I think you can defined the "address" setting multiple times in ifupdown | 10:31 |
| CsokiCraft | Okay, so you can't have multiple `address`es, but you can have multiple `iface eth0` definitions, with different addresses, netmasks etc. However, `netplan migrate` still doesn't convert that to multiple `address`es on one interface, it just keeps the last one defined | 12:38 |
| danilogondolfo | there is one example with 2 addresses in the man page https://manpages.debian.org/unstable/ifupdown2/interfaces.5.en.html | 12:40 |
| danilogondolfo | I know it's for 1 ipv4 and 1 ipv6 but I'd expect it to work with multiple addresses from the same family... | 12:41 |
| danilogondolfo | See this example https://git.launchpad.net/ubuntu/+source/ifupdown2/tree/docs/examples/interfaces | 12:43 |
| danilogondolfo | But still, I don't know if "netplan migrate" understands it... | 12:43 |
| CsokiCraft | Well, it doesn't: `ifup: duplicate option "address"` | 12:51 |
| CsokiCraft | At least not with BusyBox v1.35.0, which is what the old firmware uses... | 12:51 |
| CsokiCraft | Full log: | 12:52 |
| CsokiCraft | root@mymachine:~# cat /etc/network/interfaces | 12:52 |
| CsokiCraft | # /etc/network/interfaces -- configuration file for ifup(8), ifdown(8) | 12:52 |

| CsokiCraft | And FYI even `netplan migrate` doesn't seem to handle multiple addresses in one `iface` stanza... | 13:06 |
