Connect with database standing on host which requires SSH connection using Qt

Hi,
@Christian-Ehrlicher suggested to change the port on your local host side to avoid the clash no the two. You can also disable temporarily your local PostgreSQL during the testing.

@marcus74 said in Connect with database standing on host which requires SSH connection using Qt:
I've done it on screen and it didn't work as well
ssh -L 5000:localhost:22 userFromAboveHost@host.with.database.comNo, you're now connecting to port 22 on your database server

The procedure is pretty good (and officially) documented by PostgreSQL

@Christian-Ehrlicher On screen code I tried in second line:
ssh -L 5000:localhost:5432 userFromAboveHost@host.with.database.comand it gave above output.

Again hmm,, in the screenshot above you're using
server.using.tunnel.com(not ```host.with.database.com``)?Edit: I mean you should try this SSH:
ssh -L 5000:host.with.database.com:5432 userFromAboveServer@server.using.tunnel.com@hskoglund Again, I receive errors about not accepting TCP/IP connections. Maybe I should pass by some way a password in process object for
userFromAboveServer@server.using.tunnel.combecause in Windows cmd I am requested for password after doing this:
ssh -L 5000:host.with.database.com:5432 userFromAboveServer@server.using.tunnel.com -
Yeah, if you're establishing the SSH tunnel via a command line, then there's no stable way to submit the password.
I think putty can be used in an automatic way, or, if you have a admin rights on server.using.tunnel.com you could create keys, so that no password is needed, more for example here -
Ok, after long perturbations I used program:
https://geekflare.com/create-port-listener-in-windows-or-linux/
and created listening port 5000, then ran Qt project and everything is fine.
Thanks for all your patience :)To conclude, passing passoword as I mentioned above is not mandatory.
