feat(extractors/interface): init

Guide me through what you want done for this extractor

Right now it just shows the interfaces on the nodes.

Thanks for your contribution!

Guide me through what you want done for this extractor

Anything you can come up with really :P More seriously though, I think we can start with whatever you are comfortable implementing and we can always extend it later if we find new interesting stuff. What I usually have in mind for networking is:

• known interfaces, so what you already have
• mac addresses (if specified)
• static ipv4/ipv6 addresses (if specified)
• interface type (ethernet / wifi / macvlan / macvtap / tun / tap / ...)
• you could think about setting addresses = ["DHCP"] if you know that an interface uses DHCP (maybe we'll convert that to a new information option later)
• anything else you can come up with, we can extend the list of extracted information. For the future I have VLANs in mind but that's probably going to need changes in the renderer too.

Just pick whatever you like.

Two additional thoughts:

• I know there is a networking.useNetworkd option, which should probably control this extractor's default enable option, because the systemd extractor would in that case take care of the extraction.
• I believe I already fixed the problem behind the comment about mkMerge not working for the network propagator, but forgot to remove the comment. If you'd like, you can use topology.self as written in the comment and check if network propagation still works.

Okay thanks!

static ipv4/ipv6 addresses (if specified)

Im working on this rn

All are done!

I don't know what to add I will keep looking at the search.nixos.org reference

Generated from:

  networking.interfaces.eth0 = {
    name = "eth0";
    ipv4.addresses = [
      {
        address = "192.168.25.141";
        prefixLength = 24;
      }
    ];

    ipv6.addresses = [
      {
        address = "fdfd:b3f0:482::1";
        prefixLength = 48;
      }
    ];

    macAddress = "3abansdsjh";
  };

DHCP (just remove ip addresses from config):

interface type (ethernet / wifi / macvlan / macvtap / tun / tap / ...)

This isn't done, I missed it when I read the list. whoops :smile:

[IogaMaster]

Also can confirm that topology.self is functional!

[IogaMaster]

@oddlama I don't think there is a way that we can get the interface type?

[oddlama]

It's just something that I did for systemd-networkd. If that information isn't available on networking.interfaces then I'd say just keep the current default (which is ethernet).

I can consider this module done for now! Looking for merge!
