Coturn: TURN Server in Docker installieren

Ich brauchte kürzlich für ein Update einen funktionierenden TURN Server. Ohne den lief das neue Feature schlicht nicht. Meine erste Idee war bequem. Öffentlichen TURN Server nehmen, fertig. Kostenlose Basisversion, 20 GB Traffic im Monat, klang ausreichend.

War es nicht.

Ich hatte Verb...

Two weeks ago we published our analysis of TURN security threats. Today: how to fix them.

New guides covering implementation-agnostic best practices (IP range blocking, protocol hardening, rate limiting, deployment patterns) and coturn-specific configuration with copy-paste templates at three security levels.

coturn guide: https://www.enablesecurity.com/blog/coturn-security-configuration-guide/
Config templates on GitHub: https://github.com/EnableSecurity/coturn-secure-config

coturn 4.9.0 dropped yesterday with fixes for CVE-2026-27624 (IPv4-mapped IPv6 bypass of deny rules) and an inverted web admin password check that had been broken since ~2019. The guides cover workarounds for older versions.

#simplex #coturn #selfhosting

Few days ago I successfully configured #coturn to have a TURN/STUN server for in-family calls. But … looks like bots or some bad guys constantly trying to connect to my TURN server to use it for something :-(

Of course, it is impossible, since anonymous access or any other access without right key is impossible. But, there are no IPs of attackers in the log file, even wth "Verbose" directive — only my local and public IPs and my server's hostname  

Maybe, there is some way to force coturn to display IP addresses of connected clients, so I could ban them all with fail2ban?

So, der prosody #xmpp server läuft mit #coturn für Voice und Video, allen Features passen und wir haben 100% Compliance. Yay.

Mal sehen, was es jetzt wieder für einen Kampf wird, vom Test- auf den Prodserver umzuziehen.

Das letzte Zahnrad für die digitale Unabhängigkeit … #selfhosting

Question de noob:

Le multipath TCP ca a un interet pour les transitions entre connexions 5g/wifi les apps voip? Genre une app android #conversations qui communique en vers un service relai #coturn ?

Je crois que la voip utilise UDP en general.
