Failed connection help

If you see an error like this one:

$ ssh username@195.14.102.215
username@195.14.102.215: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,keyboard-interactive).
$

You can increase the verbosity of the client with:

ssh -vvv username@195.14.102.215

If towards the end you see some lines like these:

debug1: Offering public key: /home/username/.ssh/id_rsa RSA SHA256:mAk/jta+FlaiRfD0sB0x/UWxWU/Tv2000PDuuuPDcmi

It probably means that you are sending the wrong private key (id_rsa) to our server.

If you have chosen a different name for your keys (E.G. id_rsa_orfeo) and/or you have saved your key pair outside of the default path you have to specify the path of the private key with the following syntax:

$ ssh -i id_rsa_orfeo username@195.14.102.215

If this is not your case then there's the chance your private key is lost.

Lost private key

Please send an email to support@areasciencepark.it with subject [ORFEO] Lost private key for account username stating your user name and copying the contents of your new public key in the email body.
