A place for all topics related to the Gemini protocol, e.g., applications, capsule setup/maintenance, software development, libraries/languages, and questions about the specification.
Examples of handling TOFU and client certificates with mbedTLS (in C)? — As a rite of passage I've decided to make a Gemini client in C, and as I'm new to SSL/networking, I have no idea how to handle TOFU or client certificates with mbedTLS. Has anyone else specifically made a gemini client with it? Or would you recommend that I try to figure out another SSL library? I avoided OpenSSL because the documentation seemed incomprehensible, but mbedTLS' documentation isn't much better. As an aside, I...

Valid Gemini response with invalid media type? — Valid Gemini response with invalid media type? This is an interesting URL: [gemini link] It returns a status code 20, and a META of "text/plain\n" with a literal new line. A \r\n follows this, so per the Gemini spec, the META field contains a trailing \n character. The Gemini spec says that "For [SUCCESS status] responses, <META> is a MIME media type as defined in RFC 2046." RFC-2046 defines the media type as part of the grammar for a `...
Gemini on old platforms. — With AmiGemini existing for the Amiga platform. What other old platforms does have Gemini client? With my limited knowledge I think that SSL is the limiting factor, right? I would love to see a MS-DOS/FreeDOS etc. client.

Gemini on bare IPs — So, in case there are more people who know this stuff here, is it *in practice* possible to have a Gemini server on a bare IP? So far I haven't seen a single server that can do it, but then again I haven't checked in a while. Currently I've chosen to use Gemini-like simple HTML pages (over Yggdrasil), but still curious if things changed.

I made a tool for Linux (it'll probably work on quite a few flavors of *BSD as well and maybe macOS) that converts gemtext files to pdf using groff, aptly named "gmi2pdf". Can save as "A4", "Letter", "Tabloid", and "Legal" sized PDFs. It can take a local file or a gemtext/plaintext remote gemini resource as input. Has support for TLS client certs as well. Currently only supports ASCII characters, but can optionally convert unicode characters to squares. Some lines can look a bit weird for now...

Telescope by OP added initial certificate support! <3 — Hello folks, good news! Telescope introduced initial support for certificate in the development branch. So far only PEM certificates are allowed and the whole UX needs to be improved. Nonetheless is a great beginning and very long waited! This announce was written from Telescope :D

Gemini capsule with basic server (Agate) but managed with scripts — Amazed about how much I've learned by managing my Gemini capsule with bash scripts which I can run from a SSH connection. Today, I made improvements to the comments mechanism, yes you can get comments with Agate server.

One-line ncat Gemini server ncat --ssl -l -k -p 1965 -c "/usr/bin/echo -e \"20 text/gemini\r\nhi\r\n\"" [`] Then go to [gemini link] to view. It should display "hi". If you would like to create a certificate for your server instead of having it generate a new one every time (and thus get security warnings every time) you can do the following: 1) Create a certificate in Lagrange called localhost (or whatever the name of your server is.) 2) Click on it and choose "Show in File Manager". 3)...

Gemini using ncat: ncat --ssl --crlf example.com 1965 then when connected, type: [gemini link] and press enter Easier than using openssl. The Windows version of ncat has some problems though.

Surveillance in Gemini — Adversary can tell very specifically which one gemini page a user is requesting, based on the size of server response. There is no need to decrypt the channel to learn which page is transmitted there, the only thing that matters is the size of that message. The same thing works all the way around, if someone has submitting a picture or a text to the gemini forum, adversary can see corresponding portion of encripted traffic going from specific user. Again, there is no...

Gemini & PHP — Is there a good way to integrate/use PHP with a Gemini server and what server should I choose for that? Can I use Agate for this?

Recommended Gemini server — Hi, I’ll be migrating my server to bigger machine, and I want to use Debian. The problem is that I don’t see any Gemini server packaged in official repositories, so I might choose any, and got lost in the process. Can anyone point me which Gemini servers meet my wishlist and will be best choice? Currently I’m using Stargazer, simply because it was available in Alpine Linux repositories. My wishlist: some kind of CGI/SCGI/FastCGI support, as I want to write some cool...

With levior it's now possible to include URL rules from external config files. I'll be slowly building a library of rules that can be used to trim down the gemtext output of "heavy" webpages. Rules contributions are appreciated. Here's an example: [https link] [https link]

Big files over Gemini (was Video over Gemini) — I was thinking of how you could do Video over the Gemini protocol. And to quell any fears of bloat, I don't mean to embed video but a way to deliver video (and larger audio). My proposal is to use a playlist like file that includes the location of the video segments and timestamps of said segments, so if you want to jump around you only have to download the particular segment and not the whole file. I probably just over engineered something that...

Can a gemini response redirect to another protocol? — The spec just mentions that <META> is "a new URL", so technically any URL is fine, but I wonder if we all understand the same thing.

gemlogssh a script for gemlogging at gemini — gemlogssh is a script assistant which helps me with my capsule management (posting and keep records in my indexes and archive gems across four gemlogs hosted in there). Since today, I'm sharing it via git repository at Codeberg.

Idea for Remini: Add a "Gemini feed" link to subreddit pages that would provide a feed that could one could subscribe to in Lagrange, for example. Don't know how doable this would be, but there are a couple of subreddits that I still follow and it'd be awesome to follow them from Gemini (best possible user experience of Reddit tbh).

Encryption is a hell — Gemini encription is somewhat unusual. It relies on TOFU (trust on first use) principle. Suppose my provider is a jackass and he is implementing a MitM attack on all gemini connections, then my gemini program will not notice and all gemini capsules from this network perspective will be compromised. And if I use VPN after that, I will get warnings about certificate change. Than I have to guess where MitM attack was happened? Is it my provider messing with that, or is it a...

I am a noob, I do not know what a backlink is. Kennedy search engine has an option "backlink to capsule", is this a button I need for adding my own capsule to the search engine? Why is it called so strange then?
