Hi Casey & Gina, I want to do a postgre shift soon as well away from sql server... This is my sql server version on Windows if that could be of any help: ; ************************************************************************** ; * Global options * ; ************************************************************************** ; Debugging stuff (may be useful for troubleshooting) debug = 7 output = stunnel.log sslVersion = all sslVersionMin = TLSv1.2 sslVersionMax = TLSv1.2 ; ************************************************************************** ; * Service definitions (at least one service has to be defined) * ; ************************************************************************** ; ***************************************** Example TLS client mode services [Sql_Sil] client = yes accept = localhost:<Port> connect = <IP>:<Port> ciphers = PSK PSKsecrets = C:\Program Files (x86)\stunnel\config\pskSQL.txt I am not aware of what a UNIX socket is, why would you want to move away from TCP?

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?
