cfdyndns's Issues

SSL error

I am trying to run this service on NixOS but I am facing the following error with both the lastest tagged and master commit.

thread 'main' panicked at 'called `Result::unwrap()` on an `Err` value: reqwest::Error { kind: Request, url: "https://api.cloudflare.com/client/v4/zones", source: hyper::Error(Connect, Ssl(Error { code: ErrorCode(5), cause: Some(Io(Os { code: 32, kind: BrokenPipe, message: "Broken pipe" })) }, X509VerifyResult { code: 0, error: "ok" })) }', src/main.rs:59:10

Seems like a SSL error, but not sure since I don't really master rust

Wrong Cargo.lock in v0.0.2

Hi,

Thanks for releasing new version tag to help me with NixOS/nixpkgs#75865. But in v0.0.2, the version in Cargo.toml is updated but not in Cargo.lock, could you bump the version again.

Thank you very much

Seems like a change in Cloudflare's API?

Config: https://github.com/diogotcorreia/dotfiles/blob/bf6f0ee0fbf956d0983308f7270d7b7698e8d57d/hosts/bro/default.nix#L76-L80
Keep in mind that I'm using a patch from #56 as well.

  sops.secrets."cloudflare/cfdyndns" = { };
  services.cfdyndns = {
    enable = true;
    records = [ "domain.one" "domain.two" ];
    apiTokenFile = config.sops.secrets."cloudflare/cfdyndns".path;

}

allow setting AAAA records (ivp6 support)

It'd be quite useful to set my dynamic dns to my ipv6 address to avoid NAT issues and/or port forwarding.

cfdyndns fails when a `CAA` record (or any other unknown RR type) exists in the zone

Hey 👋,

I have been using cfdyndns for a while on my NixOS systems and it worked without any issues 👍.
Recently, I added a CAA record to my zone using the CloudFlare WebUI. Since I added this record of type CAA cfdyndns fails with an error:

Feb 22 14:25:00 MY-HOSTNAME cfdyndns-start[1661398]:  INFO  cfdyndns::ip > 93.XXX.XXX.XXX
Feb 22 14:25:00 MY-HOSTNAME cfdyndns-start[1661398]:  INFO  cfdyndns::ip > 2001:a61:YYYY:YYYY:YYYY:YYYY:YYYY:YYYY
Feb 22 14:25:03 MY-HOSTNAME cfdyndns-start[1661398]: Error: error decoding response body: unknown variant `CAA`, expected one of `A`, `AAAA`, `CNAME`, `NS`, `MX`, `TXT`, `SRV` at line 1 column 3357
Feb 22 14:25:03 MY-HOSTNAME systemd[1]: cfdyndns.service: Main process exited, code=exited, status=1/FAILURE

I redacted some fields for privacy reasons.

A quick search on the source code lead me to

cfdyndns/src/dns.rs

Lines 72 to 83 in bd02dd0

 match self { 

 DnsContent::A { content: _ } => "A", 

 DnsContent::AAAA { content: _ } => "AAAA", 

 DnsContent::CNAME { content: _ } => "CNAME", 

 DnsContent::NS { content: _ } => "NS", 

 DnsContent::MX { 

 content: _, 

 priority: _, 

 } => "MX", 

 DnsContent::TXT { content: _ } => "TXT", 

 DnsContent::SRV { content: _ } => "SRV", 

 }

I assume extending this would suffice to address this issue.
Given sufficient time I might contribute a fix myself though for now I can not tell when that might be the case.

small failure on update of my nixos system.
Not sure why, just reporting in case it's helpful.

FR: support user API keys

It would be nice to to use users API keys and not the global key.

transfer ownership to nrdxp

Hi, @nrdxp,

GitHub is being picky.

nrdxp already has a repository in the colemickens/cfdyndns network

Want to delete your fork and I'll do the transfer again?
