SQL Data Source through ssh tunnel

Hi,
You need to open your tunnel or VPN without RDM first. Even with that I'm not sure if it's possible.

Are you able to do that from SQL Management Studio? I think that SQL Server use multiple ports to establish the connection.

Regards

Yes from SQL Management Studio I can connect through ssh tunnel. Application unfortunately can't.
After click test server i have got connection time out.

Could you send me your connection string in private for SQL Management Studio?

Regards

Please send me your email.

When I try connect to DB I've got error:

We should have a fix in RDM 12.0.3.0 for this issue, when it is out could you try it and give us some feedback? Thank you.

Hi
I've just tried beta version 12.0.3.0 but tunnel still don't work.

Hello,

I'm unable to reproduce your issue. Are you using the SSH Tunnel entry type for your tunnel or are you using a different entry type? If you are using a different entry type could you try using the SSH Tunnel entry (not the one marked Rebex).

Regards,

SSH Tunnel entry (not the one marked Rebex) works thanks.
Now I have to create xml with this connection as a sample before connect to MSSQL PROD DB.

Thanks for trying it out Grzegorz. Unfortunately since Rebex is a third party we don't have full control over it and I'm unsure if we can support this, which is why we encourage our users to use the non-rebex SSH Tunnel and shell. For now the workaround would be to use the SSH Tunnel entry rather than the rebex one. Sorry about that.

Regards,
