Title: NT10 Letsencrypt and DNS
Post by: Sibuya on January 12, 2019, 10:56:32 AM

Hi,

Port 80 is blocked by my ISP and I'm unable to present challenge to Letsencrypt using http file challenge and Letsencrypt don't allows me to change port number to other than 80.

There's another way to do this using dns challenging where challenge is set in DNS TXT record. I'm using dynamic DNS duckdns.org and with a simple GET I could set and clear DNS TXT record.

Is there a way to use this challenge option?

Thank you.

Best regards,

Marcos Sibuya

You're ISP blocks port 80?  That's weird.  I'm guessing they charge extra for that.

I think you'll have to use port 80.

I recommend signing up for Amazon AWS.  You can have an affordable virtual server setup in a few minutes and you can do pretty much anything you want with it.  You can choose from multilpe operating systems up to Windows Server 2016.  Their domain registrar, Rout53, is pretty nice to.

I'm pretty sure Bruce has covered setting up an Amazon server in one of the user group webinars.

Hi,

This is a low budget project and I'm preparing to deploy it.

I'm just trying to figure out on how to renew LE automatically using Duckdns.org provider.

I renwed LE manually using Certbot in Windows 10 Ubuntu and have to create scripts to be done because it depends on dynamic dns provider specific commands to set and clear TXT DNS record.

I'll study a way to do it by using Certbot.

The explosion of LE is remarkable because big companies like IBM are using it in their products.

Thank you guys!
