How can I federate my server with onion servers?
First, you should make sure Tor is installed on your server. Then, there's two ways to go about it. Prosody server has excellent Tor/onion integration with mod_onions.
If you don't want to use this module, or are not using Prosody, you may consider configuring Tor as a transparent proxy. Tor will answer to DNS queries about onion services (for example, on port
5352), announcing a record for a local address (for example in the
127.192.0.0/10 range), which iptables will forward through Tor's SOCKS5 proxy (for example,
Step 1: Add to Tor config (usually
VirtualAddrNetworkIPv4 127.192.0.0/10 VirtualAddrNetworkIPv6 [FE80::]/10 AutomapHostsOnResolve 1 TransPort 127.0.0.1:9040 TransPort [::1]:9040 DNSPort 5352
Step 2: Add in iptables config (usually
-A OUTPUT -d 127.192.0.0/10 -p tcp -j REDIRECT --to-ports 9040
Step 3: Add in dnsmasq or other resolver's config (usually
Finally, configure your DNS resolver to use Tor's exposed transparent onion resolver as source of authority of ".onion" domain. For example, with dnsmasq you may simply add to
