IPv6 and HE certification web server question

@Gertjan said in IPv6 and HE certification web server question:

I don't think HE will ask you to fire up a mail server

You misunderstand. You need to be "sage" to be able to open port 25 incoming with HE. I just asked what else you gonna gain.

[Gertjan]

@Bob-Dig

aahhhh, I get it.
HE can be considered as an ISP, and as such - see above - the will block "TCP 25".
So being sage unblocks that ? Nice to know.

[Bob.Dig]

@Gertjan Yepp. Go to your tunnel and then klick on advanced. If it is not there when you are "sage", you might have to contact support.

@Gertjan said in IPv6 and HE certification web server question:

Btw : there should also be a comparable test for DNSSEC test. And a Letsencrypt-like certificate (certification ) test. With these two, "DANE" becomes possible and that will be the end of all CA's as they are not needed anymore.

I stopped using DANE because it became to burdensome with Letsencrypt. Sadly.

But you are right, something certbot-like together with DANE could end things.

Here : this will take care of your issues : https://dnssec-stats.ant.isi.edu/~viktor/x3hosts.html

Add these to your zone :
I have a domain name 'test-domaine.fr', and added the current 5 signing certificate hashes :

$ORIGIN mail.test-domaine.fr.
_25._tcp	TLSA	2 1 1	2bbad93ab5c79279ec121507f272cbe0c6647a3aae52e22f388afab426b4adba
_25._tcp	TLSA	2 1 1	6ddac18698f7f1f7e1c69b9bce420d974ac6f94ca8b2c761701623f99c767dc7
_25._tcp	TLSA	2 1 1	919c0df7a787b597ed056ace654b1de9c0387acf349f73734a4fd7b58cf612a4
_25._tcp	TLSA	2 1 1	025490860b498ab73c6a12f27a49ad5fe230fafe3ac8f6112c9b7d0aad46941d
_25._tcp	TLSA	2 1 1	f1647a5ee3efac54c892e930584fe47979b7acd1c76c1271bca1c5076d869888
_25._tcp	TLSA	2 1 1	8D02536C887482BC34FF54E41D2BA659BF85B341A0A20AFADB5813DCFBCF286D

and now I'm good up until the moment these start to fade out, and new one get added and used.

Check here : https://dane.sys4.de/smtp/test-domaine.fr - one of them matches, so DANE will be ok.
I'm using Letsencrypt certs for everything : web, smtp, pop, imap, you name it.

[Bob.Dig]

@Gertjan Thanks but I pass. Also, no one had a problem with my servers when DANE was failing...

Well they had a problem with the info you published in your DNS zone info ^^
Publish the correct info, and everybody is happy.
Like DKIM - like SPF - like DMARC. Like a correct reverse host name. H*ll, like a certificate on your web and mail server that is in the 'valid' for your servers. Like DNSSEC.
Some of them are a must have these days, some are more or less optional.
Try sending a mail from your domain - mail server to a gmail, and then check how gmail 'scores' your mail.

And normally, we don't want a A+ because it's looks nice (no one cares actually), we want the A+ because it means we probably, maybe, understood the things we work with.

[Bob.Dig]

@Gertjan No A+ for me because I don't run any public web server.
And there is no score in an email to gmail right? It just says if you passed the usual stuff.
But I "enabled" gmail's Postmaster Tools now. Probably will do nothing because I rarely send email.

Understanding of IPv6 and how it functions being the top one to be honest. And the cool tshirt..

[JonathanLee]

@Gertjan Ooooo yeah!!!

mirroredanalytics.com is up and running :) ipv6 and ipv4

Now I have to create a ipv6 webserver with the port 25 thing you guys are talking about. I am going to use iRedMail over Kali. I just have to make a new copy of Kali my current one is to old to download anything anymore...

Got to tell you I loved my old CD days with PHLAK linux Pen testing software

[JonathanLee]

I can almost make a post in the HE forum ... almost to sage...

I just need An IPv6 enabled mail system, with working RDNS.

The last step took my gmail as a working ipv6 email. I guess there was a time that was not the case...

[johnpoz]

@JonathanLee If I recall with the email section - I just used their free dns and setup the PTR records, etc.

[JonathanLee]

@johnpoz thanks for the recommendations again!!

I know the basics of IPv6. I can configure an ipv6 webserver that is behind a secure firewall inside of a IPv6 tunnel broker that tunnels inside of a IPv4 only ISP provider. I can manage and parse out AAAA records for streaming services that do not support tunnel brokers. I understand glue-records and have my website mirroredanalytics.com working (just the basics I have not spent any time really designing it. Right now, my web server is still under construction) YEAHHHH Buddy!

Plus they said I get a T-Shirt :)
