Title: I don't get any incoming connections to my tor hidden service
Post by: Relaxo143 on November 01, 2019, 10:40:55 AM
I'm trying to run Bitcoin Core entirely over Tor. Everything with the outgoing connections is ok, but I don't get any incoming connections, even though I see
2019-11-01T10:26:18Z tor: ADD_ONION successful
2019-11-01T10:26:18Z tor: Got service ID 6yewk7gn3ifmvudz, advertising service 6yewk7gn3ifmvudz.onion:8333

in the logs. I also tried to check if the node is available with https://bitnodes.earn.com/. It doesn't work with the .onion address. Any ideas?
I also noticed a weird thing: I got one inbound connection from localhost... how is this possible? I don't run any other nodes. https://imgur.com/a/49gGNwE

update: Actually I think incoming connections will always say 127.0.0.1 since I specified bind=127.0.0.1 when in fact they are over tor. Am I correct?

Bitnodes is not 100% reliable. Your hidden service is definitely up: I can connect to it without problems. There are no errors in the log you posted either.

I also noticed a weird thing: I got one inbound connection from localhost... how is this possible? I don't run any other nodes.
A Tor hidden service works as a reverse proxy (https://en.wikipedia.org/wiki/Reverse_proxy): other users connect to your Tor server, which forwards the connection to your Bitcoin node, which sees the connection as coming from the IP address of your Tor server (localhost if both Tor and Bitcoin are running on the same machine). This is exactly what you should expect to see if your hidden service is working normally. Over time, you should start to see many more such connections.

EDIT:

No, bind simply blocks all incoming connections from any other IP address (ie, clearnet connections). Even if you omit the bind option to accept clearnet connections, you will still see Tor connections coming from localhost.
