SSH Tunnel Issues

Hello,

Thank you for contacting the support department, may I ask you what is the version of RDM that you are using?

Also, some time using 127.0.0.1 and localhost at another place could cause some issue like that.
Could you try on chrome using http://127.0.0.1:12345 and tell me if it works well?

Another test will be to change the local port for an ephemeral port that is free faster by the computer so a port between 49,152 and 65,535.

Regards,

Hi David,

Running 2020.1.20.0 64bit on Windows
I tired the following

• Changing the source to localhost
• accessing chrome using http://127.0.0.1:12345 and http://localhost:12345
• No luck

• Changing the source to port to 58816
• accessing chrome using http://127.0.0.1:58816 and http://localhost:58816
• No luck

Hi David,

I think the error could be the result of a tunnel inside a jump server connection. I would like to do a remote session and look at this with you.

You will receive in the next minutes an email from our ticket system to book a remote session.

Regards,

Thanks David.

Hi David,

After investiguation with the engineering department, to support this command we will need to add the Proxy / Jumphost tab for the SSH Tunnel entry.
A feature request has been open with the engineering department. (RDMW-5198)

Regards,

HI,

The proxy tab for SSH Tunnel and SSH Port Forwarding has been added in the latest release of RDM (2020.2.10.0).

This beta version can be downloaded at https://remotedesktopmanager.com/home/download#Beta

If you could please test it and inform us the result of it?

Regards,

Apologies for the reviving of the old thread. I was trying to accomplish something similar...
Edit: may be not a good idea to revive a 4 year old thread. Will post my question separately.

@everyone,

The new post that alex2 mentioned is here https://forum.devolutions.net/topics/42397/ssh-forward-remote-port-to-local#194625

Best regards,
