Some bizarre exception when using SSH key to log on

[nskmda]

Team,

I'm getting the following stack trace when using an SSH key to connect to the target server (actually, an outdated one, for which I had to enable ssh-rsa "stuff".

Here's the trace:

failed to parse public key

do you need any other log messages or this might be telling you something about the key I'm using? maybe the key is wrong or something?

The key is ssh-rsa (in the public portion) and in the private portion it says -----BEGIN RSA PRIVATE KEY-----

Hi @nskmda,

The byte[] pubkey argument you are passing to the JSch.addIdentity() would appear to be an empty array instead of a an actual ssh public key string.

Thanks, Jeremy

@norrisjeremy

The byte[] pubkey argument you are passing to the JSch.addIdentity() would appear to be an empty array instead of a an actual ssh public key string.

So, is it safe to pass null if I don't happen to immediately have the public key info (so that I don't need to try to pull it out of the private key material)?

If yes, you can close the request.

Hi @nskmda,

Yes it should be fine to pass null if you don't have the public key.

Thanks, Jeremy
