This plugin allows Prosody to connect to other servers that are running as a Tor hidden service. Running Prosody on a hidden service works without this module, this module is only necessary to allow Prosody to federate to hidden XMPP servers.

For general info about creating a hidden service, see


This module depends on the bit32 Lua library.

To create a hidden service that can federate with other hidden XMPP servers, first add a hidden serivce to Tor. It should listen on port 5269 and optionally also on 5222 (if c2s connections to the hidden service should be allowed).

Use the hostname that Tor gives with a virtualhost:

VirtualHost "555abcdefhijklmn.onion"
    modules_enabled = { "onions" };


Name Description Type Default value
onions_socks5_host the host to connect to for Tor’s SOCKS5 proxy string “”
onions_socks5_port the port to connect to for Tor’s SOCKS5 proxy integer 9050
onions_only forbid all connection attempts to non-onion servers boolean false
onions_tor_all pass all s2s connections through Tor boolean false
onions_map override the address for a host table {}

By setting onions_map, it is possible to override the address used to connect to a given host with the address of a hidden service. The configuration of onions_map works as follows:

onions_map = {
    [""] = "ijeeynrc6x2uy5ob.onion";

or, to also specify a port:

onions_map = {
    [""] = { host = "ijeeynrc6x2uy5ob.onion", port = 5269 };


0.8 Doesn’t work
0.9 Works
