My onion (Tor) capsule is:
gemini://nreqeynb23uo5btcibmpgj3xzrb7rdoe3bojab56golipzysgbbiavid.onion/
In `/etc/tor/torrc`:
HiddenServiceDir /var/lib/tor/gemini/ HiddenServicePort 1965 127.0.0.1:1965
(You don't need to use 1965 in `127.0.0.1:1965`, just be sure that this port is the same as in the Gemini server configuration.)
Restart Tor. You will find the name of the capsule:
% cat /var/lib/tor/gemini/hostname nreqeynb23uo5btcibmpgj3xzrb7rdoe3bojab56golipzysgbbiavid.onion
I used Molly-Brown as the server. Since the server must listen only to local addresses, it has to bind to `127.0.0.1` (or `::1`). Unfortunately, Molly-Brown does not offer a way to bind only to these addresses. I had to patch it:
% git diff
diff --git a/main.go b/main.go
index a616351..a291d9c 100644
--- a/main.go
+++ b/main.go
@@ -63,7 +63,7 @@ func main() {
}
// Create TLS listener
- listener, err := tls.Listen("tcp", ":"+strconv.Itoa(config.Port), tlscfg)
+ listener, err := tls.Listen("tcp", "127.0.0.1:"+strconv.Itoa(config.Port), tlscfg)
if err != nil {
errorLog.Println("Error creating TLS listener: " + err.Error())
log.Fatal(err)
Once it is done, `go build`to recompile, `go install`.
Don't forget to put the onion name in Molly-Brown configuration file:
Hostname = "nreqeynb23uo5btcibmpgj3xzrb7rdoe3bojab56golipzysgbbiavid.onion"
Then just run Molly-Brown.
Here is a test with the command-line client Agunua and the Tor wrapper torify:
% torify agunua -i -d gemini://nreqeynb23uo5btcibmpgj3xzrb7rdoe3bojab56golipzysgbbiavid.onion/

# Stéphane Bortzmeyer's Gemini server
This is mostly an experimental server. You will not find a lot of content.
