Hello,

Which version of java do you use? The updates for Talend products delivered in May 2024 came with the requirement to start most of the modules with Java 17.

https://help.talend.com/en-US/installation-guide-windows/Cloud/compatible-java-environments

What's your key type? Is it ssh-ed25519?

Here is an article about:

https://github.com/mwiede/jsch#are-ssh-ed25519-ssh-ed448-curve25519-sha256-curve448-sha512--chacha20-poly1305opensshcom-supported

I'm supposing you need either higher version of java or add bouncy castle with a tLibraryLoad component.

Best regards

Sabrina

Hello,

I downloaded the Bouncy Castle and included that in tLibraryLoad component. I got the same error.
I am not sure how to tell what the key type is. I am fairly new to Talend.
I am trying to upgrade an existing project from Talend 7 to Talend 8

Thank you.

Hello,

1. Please try adding the parameters below to the "Config client" option of tFTPConnection as below and let us know if that resolves the issue:
Client Parameter : "PubkeyAcceptedKeyTypes"
Value : "ssh-rsa"

or
JSch.setConfig("PubkeyAcceptedKeyTypes", "ssh-rsa," + JSch.getConfig("PubkeyAcceptedKeyTypes"));

https://help.talend.com/en-US/components/8.0/ftp/tftpconnection-standard-properties

2. If the suggestion above does not work, can you please try using downloading jsch-0.1.55 and see if that allows the job to run? This can be added to your job using tLibraryload or using the "Custom maven uri"/manually adding the jar in Studio.

Best regards

Sabrina

Hi Sabrina,

Thanks for the recommendations.
RE:

1. I am using tFTPPut component, and I added Client Parameter : "PubkeyAcceptedKeyTypes"
Value : "ssh-rsa".

However, I am not sure how to add:JSch.setConfig("PubkeyAcceptedKeyTypes", "ssh-rsa," + JSch.getConfig("PubkeyAcceptedKeyTypes"));

2. I added tLibraryload component using jsch-0.1.55.jar; and that one also errored out. However, this time the error is different :

Hello,

The "Config client" option is available in tFTPConnection component which is used to set JSch encryption algorithm properties.

Please use tFTPConnection-->onsubjobok-->tFTPPut to put files onto an FTP server.

Best regards

himanshup — Thu, 08 Aug 2024 17:26:57 GMT

Thanks Sabrina,

Where do I use:
JSch.setConfig("PubkeyAcceptedKeyTypes", "ssh-rsa," + JSch.getConfig("PubkeyAcceptedKeyTypes"));

Also,

I added tFTPConnection component with Client Parameter : "PubkeyAcceptedKeyTypes"
Value : "ssh-rsa".;
Then tFTPConnection-->onsubjobok-->tFTPPut.
Added bouncy castle and jsch-0.1.55.jar in tLibraryLoad component for each; I get this INFO/Exception messages with Exit Code = 1:

Hi,

I have tried to open a support ticket, with no success.

Then support person helped me open a case, case number 00302380,. But I am not able to see that case at all.

This is where i log into to check my case:

https://status.qlikcloud.com/

I don't see any thing, Says: No incidents reported today. (yesterdays date and todays date as well).

This is very frustrating., I wish some one could do a zoom or a session where I can share my screen and demonstrate what I am experiencing.

I need to have this issue escalated. Can you help with that?

Hello,

My job is now functioning as expected.
I deleted the project from Git. Re-Imported it into Git. Then I renamed the project folder in my workspace folder. Then I added one client parameter in tftpput component;

Client Parameter : "PubkeyAcceptedKeyTypes"
Value : "ssh-rsa"

The job ran successfully after the above steps.

Thank you.
Since I can't access the ticket(Case number 00302380) that was created for me by support, I ask that it be closed, if possible.

Thank you.
