I'm pleased to announce that tanelorn.city is now open. I'm catering mainly to writers, but TBH I'll probably give an account to anybody who wants one as long as they aren't a fascist, a white supremacist, or a TERF. -- Matthew Graybosch gemini://starbreaker.org #include <disclaimer.h> gemini://demifiend.org https://matthewgraybosch.com gemini://tanelorn.city "Out of order?!

Amen. Happy to have another server! However, in Bombadillo I get the error "Cert hostname does not match". Make sure you're serving up the right certificate! makeworld ???????

I just downloaded Bombadillo so I could see for myself, and checked my Gemserv config on kanajana. As far as I can tell my config is OK and I'm using the correct cert for each hostname, but the problem might be that kanajana isn't only serving tanelorn.city but demifiend.org and starbreaker.org as well. I'm not sure what to do about it, though since all three sites are accessible using Castor and bollux. -- Matthew Graybosch gemini://starbreaker.org #include <disclaimer.h> gemini://demifiend.org https://matthewgraybosch.com gemini://tanelorn.city "Out of order?!

Kristall and elpher also show no error, by the way.

I guess various best practices for non-conventional certificate validation should be hashed out in, well, the best practices doc, or even a dedicated document. For what it's worth, AV-98 expects either the Subject CN or one of the SubjectAlternativeNames to match the hostname in the URL it's trying to fetch and will complain otherwise. I can visit tanelorn.city just fine, so I guess there's a valid SAN that perhaps Bombadillo isn't seeing? Cheers, Solderpunk

I might have gone about creating my certs the wrong way, too.
After RTFMing FreeBSD's openssl implementation I came up with the
following shell script.
```
#!/bin/sh
DOMAIN=${1}
SSL_CERT_PATH=/usr/local/etc/ssl/${DOMAIN}
if [ ! -d "${SSL_CERT_PATH}" ]; then
mkdir -p $SSL_CERT_PATH
fi
openssl req -x509 -nodes -days 365 -newkey rsa:4096 \
-keyout ${SSL_CERT_PATH}/ssl.key \
-out ${SSL_CERT_PATH}/ssl.crt
openssl dhparam -out ${SSL_CERT_PATH}/dhparam.pem 4096
```
It looks like I'm getting prompted to create a CSR for each cert as
well, and I might be putting in the wrong information.

I think it should be noted, that to my knowledge, Kristall, Elpher, Castor and Bollux all do not check certs. makeworld ??????? Original Message ???????

TOFU implementation and certificate-checking is on the Very Important list for writing. So there's another good reason to make sure the certs work.
