Hi! I'm trying to set up stunnel for postgres, and cannot get it working. For the moment, I'm just trying to test locally on a Mac. I have set up postgres SSL correctly and confirmed that direct connections to the db with psql work with SSL. Here's the most promising config I've come up with: foreground = yes client = yes [postgresql] protocol = pgsql accept = 127.0.0.1:5433 connect = 127.0.0.1:5432 verify = 0 cert = /opt/homebrew/var/postgresql@16/server.crt key = /opt/homebrew/var/postgresql@16/server.key CAfile = /opt/homebrew/var/postgresql@16/ca.crt Here's what I'm getting: $ PGSSLMODE=disable psql -h 127.0.0.1 -p 5432 -U casey -d postgres -c 'select 1' -At 1 $ PGSSLMODE=require psql -h 127.0.0.1 -p 5432 -U casey -d postgres -c 'select 1' -At 1 $ PGSSLMODE=disable psql -h 127.0.0.1 -p 5433 -U casey -d postgres -c 'select 1' -At psql: error: connection to server at "127.0.0.1", port 5433 failed: server offered SCRAM-SHA-256-PLUS authentication over a non-SSL connection $ PGSSLMODE=require psql -h 127.0.0.1 -p 5433 -U casey -d postgres -c 'select 1' -At psql: error: connection to server at "127.0.0.1", port 5433 failed: FATAL: unsupported frontend protocol 1234.5679: server supports 3.0 to 3.0 Also, is it possible to connect to stunnel via UNIX socket instead of TCP? Thanks, -- Casey
