Cloudflare inadyn stopped working

[Laxarus]

Hello guys,
RT-AC5300 merlin 384.19

I have been using inadyn for some time now. without a problem however today I noticed an inadyn issue in the logs. I have been trying a number of things to fix this but got no results. I know that there is a newer merlin firmware but currently it is not possible for me to update it (after a month maybe?).

Is there anyway for me to patch this up to get it working? Any suggestion is welcome.

I know that there is an indayn update in the new 386.2 alpha. I don't think you can update this in the firmware you're running without compiling it with the new inadyn version 2.8.1. You would have to upgrade to the latest alpha release to see if it fixes your issue.

Asuswrt-Merlin 386/NG Changelog
===============================

386.2 (xx-xxx-2021)
- UPDATED: inadyn to 2.8.1.

Updating mw firmware is definitely in my to do list but it is going to take a bit of time due to some other problems in my home setup. I wonder is there any other temporary fix. If not, I will just disable ddns until then. I noticed that due to inadyn constantly failing, the overall stability of the unit is compromised.
What I noticed so far,
- High CPU and memory usage after some time.
- Inability to access GUI
- Responsiveness

Having the same issue as well, hopefully the new alpha/beta with the updated indayn resolves the issue

How do you update you cloudflare domains ip? I'm using dnsomatic but I'd really wanted to use a direct solution

Yeah, but specifically with cloudflare... I was never capable dealing with the api and it never worked with me

First, you need to have a domain managed by cloudflare.
Then you have to create an API key from your cloudflare domain page.
Inadyn documentation covers what to do exactly

When my wan up changes, does inadyn auto detects that change?
Or what's the frequency for it to run?
I set it at 8pm. It's now 9pm and looking for the logs, it didn't run again.

Those are my only two configured files. I don't see a cron job. Are they ok? Or did I miss something?

Because, it doesn't need to run. It runs with ddns-start script. This means that as soon as your router establishes an internet connection, it runs. You don't need to set up any time or frequency. For your WAN ip to change, your internet connection needs to go down momentarily. So, when your router reconnects, inadyn runs.

Thanks for your explanation perfectly clear!

Is it possible to update an AAAA record using this?

Also... If I set on webui to get internal Ip, does it get internally? Because I'm seeing yahoo queries each time inadyn runs. So I assume it is getting the ip externally.

I am not exactly sure. If you can make sense of it, you can take a look at the file.

I'm afraid I don't understand the In-a-dyn configuration for Cloudflare:

provider cloudflare.com {
    username = zone.name
    password = api_token_important_read_comment
    hostname = hostname.zone.name
    ttl = 1 # optional, value of 1 is 'automatic'.
    proxied = false # optional.
}

Suppose my domain name is "domain.net". What should I use for "username" and "hostname" in the configuration file?

 

[XIII]

Do these sample configurations on Github help? https://github.com/troglobit/inadyn/tree/master/examples

Unfortunately not, because they use the same cryptic terms (that I don't understand) as the configuration I quoted:

• zone.name
• hostname.zone.name

It's not clear to me what those should be.

I don’t use any of this myself, but if your domain (zone) is domain.net, then the username would be domain.net. The name you want to update within domain.net (e.g. myrouter.domain.net) would be your hostname.

How did you end up choosing Cloudflare if it didn’t make sense to you?

My domains are registered by a registrar that does not offer an API, so I decided to use the free Cloudflare plan nameservers for my domains to:

• automatically update router.domain.net
• automatically create and renew Let's Encrypt certificates for router.domain.net (and a few more subdomains)

Not knowing how to do it yet is hopefully not a problem, because learning about this was a secondary reason to chose this setup.

I use the router's inadyn to dnsomatic (in the WebUI) and then dnsomatic pushes to cloudflare. No fiddling required

I’d like to prevent yet another step/party in the mix...

your call, obviously. it helps me push out my IP to multiple providers, or did I should say back when I used OpenDNS.
