Hi,
We can't see the screenshot on our side. Could you attach it on the forum, please? That would be great.
Best regards

Hi xdshi,
I'm also trying the same and getting the below exception,
: z_tdmig_dev.shell_copy_0_1.Shell_Copy - tSSH_1 - Connection attempt to 'XXXDBDA03' on the port '22' as 'ramakrn'.
: z_tdmig_dev.shell_copy_0_1.Shell_Copy - tSSH_1 - Authentication using a public key.
: z_tdmig_dev.shell_copy_0_1.Shell_Copy - tSSH_1 /home1/ramakrn/.ssh/id_rsa (No such file or directory)
disconnected
Exception in component tSSH_1
java.io.FileNotFoundException: /home1/ramakrn/.ssh/id_rsa (No such file or directory).
I have created the key file seeing the link below by logging into ramakrn user,
https://www.linode.com/docs/security/use-public-key-authentication-with-ssh
I have given "/home1/ramakrn/.ssh/id_rsa" in Private key field.
Kindly help.
