tunneling arbitrary TCP protocols like ssh or postgresql over localhost.run custom domains

README.md

1. instal stunnel from your package manager. This allows you to wrap any TCP protocol (ssh, postgresql, mysql) in TLS.

2. download the stunnel.conf from this gist and replace the example.com host with your custom domain (also in the ssh command below).

3. run stunnel stunnel.conf in a terminal

4. connect your localhost.run tunnel on port 80 to your backend service.

   ssh -R example.com:80:localhost:5432 plan@localhost.run connects a tunnel to a local postgres on port 5432, change the port for other services

5. connect your client to port 9999 (or what ever port you specified in stunnel.conf), for eg:.

   • psql postgresql://localhost:9999/dbname
   • mysql -h localhost -P9999
   • ssh localhost -p 9999

stunnel.conf

foreground = yes
pid = ./stunnel.pid
[lhr]
client = yes
accept = localhost:9999
connect = example.com:443
