ssh key forwarding (smart card login) crashes RDM

Hello Patrick,

Thank you for reaching out to us regarding this,

I see, was this working for you without issues in a previous version of RDM?

Would it be possible for you to create a portable installation of the latest version of RDM and see if this issue still occurs? To do so, you will need to do the following:

1- Download the .zip file below:

https://remotedesktopmanager.com/home/thankyou/rdmbin

2- Create a new folder on your Desktop

3- Extract the content of the .zip file into the folder created at #2

4- Go to this folder once the .zip file has been extracted and run remotedesktopmanager.exe

5- Connect to your data source

Let me know,

Best regards,

Hello Samuel,

thank you for your response. My colleague who is the admin of the RDM installation creates a test installation with the newest version of RDM. I will test as soon as possible.

The installation requires a newer version of the database as well, so I cannot test it with the database version right now.

Best regards

Patrick

Hello Patrick,

Thank you for your reply,

No need to upgrade your database for this test, you can use a Local SQLite data source to confirm if you encounter the same behavior.

To create one simply go under "File" -> "Data source" and press the "Add new data source" (+) button, once done select SQLite and recreate your entry configuration.

Let me know the results.

Best regards,

I did that and got the same experience. The RDM crashed completely, meaning the whole window disappears and I have to restart the program.

Create ssh connection

set hostname

set username

enable "Use smartcard" with Certificate method CAPI

in Advanced Tab enable "Allow SSH authentication agent forwarding"

Log into the server with ssh

open another ssh session from there and during opening the RDM window dissapears

For authentication I used a YubiKey with the YubiKey Smart Card Minidriver 4.1 x64 and WinCrypt SSH Agent x64

Hello Patrick,

Thank you for your reply,

I see, do you have any logs from this crash directly in the application under "Help" -> "Application Logs"?

If not, could you have a look in your Windows event viewer and let me know if you find anything?

Best regards,

Hello,

I can confirm the same problem still exists with version 2023.3.32.0, both the fully installed version and the portable. When agent forwarding is enabled with CAPI smart card flag, the application crashes when jumping to a second host, or when querying if agent forwarding is enabled with a "ssh-add -L" command.

Any update here? Willing to test betas!!

Love the product otherwise,

Lee

Sorry for the late reply, was busy with other things.

I looked under "Help" -> "Application Logs", but it is nothing there.

I cleared all entry, let the application crash again and the log was still completely clean.

I translated the event log entrys from german:

RDM:

An error occurred while sending a data source event: An error occurred while sending the request.

I can reproduce the bug, I will need to investigate it to give more details.

Regards

Still no update on this?

A workaround is to use a powershell window and do an:

ssh -A username@host

This works fine, but is is not working from within the RDM

Hello,

Are you encountering a crash of the application when performing smart card login? If so, could you try out the latest version of RDM? The fix for this has been available since 2023.3.34.0. If you encounter a different issue, we would need you to give us more information on the behavior, by way of sending us the application logs in RDM as well as the terminal logs (in the SSH shell entry, enable the logs, in verbose level 2, this will generate a file).

Regards,

I will try the latest version next week, I am still on 2023.2.22.0

Thanks for the Update!

Hello Patrick,

Thank you for your reply,

No problem, let us know if the issue persists for you after updating.

Best regards,

I will do, but I have to wait for my RDM admin, he will deploy the newest version.

Hello,

Thank you for your reply,

No problem, I will wait for your return on this,

Best regards,
