Linux Platform SSH – Shared Key Path

Hi all,

We are trying to configure an element using the Linux Platform SSH connector, version 1.0.1.15, where the preferred authentication method is "Public Key Authentication". Unfortunately, the element keeps getting into timeout and we suspect it's related to how the "Shared Key Path" is formulated.

"Shared Key Path" parameter's description refers to "Shared Key Path, Private Key", however we have tried using what's requested and still the connection could not be established, and the element went into timeout again.

Using the same Public and Private Key works well when using PuTTY.

We do not believe this could be related to any Firewall rule blocking the access as the "Password Authentication" method works just fine - nevertheless, it's not the preferred authentication method.

Could you please clarify what should be placed in the "Shared Key Path" parameter?

Thank you in advance.

Hi Vasco,
To troubleshoot this issue, can you have a look at the log file C:Skyline DataMinerloggingSLSsh.txt?
Maybe you are using an invalid private key?

If the key file works when using a different SSH client, it might be stored in a format that DataMiner currently does not support.

The requirements for the key file are currently:

  1. Stored in the Privacy-Enhanced Mail (PEM) format.
  2. Encrypted with the symmetric cipher 3DES in Cipher Block Chaining mode.

With the tools made available by OpenSSL, you should easily be able to convert the file in a different format and encrypted with a different cipher.
