   Please describe the feature you’d like to see added.

   • onion uses 127.0.0.1:9050 and i would like to set it to use unix:path_to_variable used by tor

   Is your feature related to a problem, if so please describe it.

   Avoid people try access local ips or 127.0.0.1 with miss configured torcc.

   This is at least partially a duplicate of #5029 with preliminary work done in #9979 and #9919

   However it sounds like your use case is a bit narrower? This isn’t about RPC or tor hidden service or P2P connections, just tor proxy?

   Just run a node using tor . there is away to set SocksPort to unix … but bitcoin seems dont have this way to set it . Just in case i resolved ask to be sure if is possible or not do that. Those implementations doesnt cover case user wish run a node using interprocess only right ?

   Example -onion=127.0.0.1:9050 -externalip=wdwudwuihdiuwhdhwhfefhiefhie.onion Example -onion=unix://path_to_soc.socks -externalip=wdwudwuihdiuwhdhwhfefhiefhie.onion

   Oh nice work @pinheadmz! I will help test #27375 too.

   I have a small bash script which uses socat to pipe between an inet and unix socket, but native support is much better:

    0#!/usr/bin/env bash
    1
    2# default tor sock on debian
    3socat -v tcp-l:9050,reuseaddr,fork unix:/run/tor/socks 2>&1/dev/null & disown
    4socat_pid=$!
    5
    6while true; do
    7    sleep 5 # check every 5 seconds
    8    if ! pgrep -x "bitcoind" >/dev/null; then
    9        # bitcoind not found, terminate socat and exit loop
   10        kill "$socat_pid"
   11        break
   12    fi
   13done
   

   (this can be run by bitcoind using -startupnotify=/path/to/the/script.sh)
