DNS domain expiration monitoring

@nebulon I'm talking about the actual domain with the registrar

I guess we could implement this through a whois query. Not sure though if this is very useful, as the registrar itself should also warn you. But I understand that this email was overlooked in this case.

I recommend looking into DomainMOD. I believe it would be a good solution to this problem.

Website: https://domainmod.org/
GitHub: https://github.com/domainmod/domainmod

I'll add it to the App Wishlist!

Why not simply filter emails like those and make sure they get your attention?

You can even set up another email with all critical notifications on that you forward those to.

Simple is good.

@robi thanks, here are the arguments:

• you can't cover all registars and I don't have much DNS domains, so domainmod is not exactly a thing
• another e-mail from cloudron is something, I would treat completely different, as opposed to another possible advertising e-mail from registar
• if cloudron will display big red warning at the top of the admin, when domain is about to expire in, let's say less than a week, this would save as well.

I understand, it might be a rare event, but, considering that a complete DNS update takes like 72 hours, quite a nasty one.

@potemkin_ai I don't get how that could happen in the first place, aren't domain renewals usually default and you have to opt-out/cancel the renewal actively?

[timconsidine]

@msbt depends on the registrar and whether auto-renewal is enabled

[potemkin_ai]

@msbt and on the client, holding DNS zone as well...

[nebulon]

I do think that is probably out of scope for Cloudron and the task of the registrar to warn appropriately about this.

Out of curiosity, is this information even available? Is whois generally considered authoritative ? For display purposes, this seems like a good idea to me. Nice to have a summary of when domains are expiring, why not, if it's a whois call away.

[msbt]

@girish the biggest problem will be the various tlds, because there is not one whois server which can do them all, you're looking at something like https://snippens.com/handbk/whois-servers or https://www.mobilefish.com/tutorials/whois_servers_list/whois_servers_list.html

WHOIS is not reliable on this at all ... I have seen several instances of whois saying a domain is about to expire when it has already been updated.

This feature would be cool, but I don't know of any way to implement this, short of having API access to various registrars.

[potemkin_ai]

it doesn't seem to be impossible thought (https://serverfault.com/questions/343941/how-can-i-find-the-whois-server-for-any-tld); and if the domain is not in whois database, you can display message, saying that your domain is not in our whois database - please, let us know what to query, if you would like us to keep you up to date with that - this way, if I'm using rare registar, who doesn't provide data to everyone, I can supply whoise server to query from this registar and be a happy user, knowing, that my Cloudron is also taking care about the DNS (without which it won't work like at all, btw).

[girish]

Looks like the whois list is available as json here - https://github.com/FurqanSoftware/node-whois/blob/master/servers.json and another here - https://github.com/weppos/whois/blob/main/data/tld.json . @potemkin_ai great link! didn't know the ways to discover whois servers.

Yeah.. same, I suspect if we add this, it will be more informational than authoritative. whois is often outdated/lags. So maybe we even let the admin set the expiry date for domains with missing/wrong whois records.

You misunderstand my point : the problem is not finding the correct whois server. That is trivial. The problem is that the information in whois responses about domain registration expiration dates is, more often than not,

[potemkin_ai]

@mehdi even if, it’s better than nothing

[robi]

@mehdi @potemkin_ai

This addresses both of your concerns:

1. Checked when the domain is added to cloudron, that's fairly reliable as the pattern is new domains get added, plenty of time. 1yr+

2. Close to that expiration date for the domain from 1. , it can warn and be checked until a renewal is detected or marked renewed. Better than 72hrs.

@girish Cloudron can keep track of this in the DB and warn/update accordingly. Easy-peasy.

I honestly don't believe so : a check that has more false-positives than true positives is not very useful... It would worry people about nothing all the time.

[potemkin_ai]

@mehdi we definitely have a different perspective here.

I believe, that giving me a chance to prevent service shutdown for 72 hours for the outside world is a very valuable thing.

I also like the idea of fetching fresh data from whois on expiration data and letting me to correct whois server or the expiration data itself.

There is little I can do to turn you into my faith, I'm just saying what I see and experience.
