Exhausted available authentication methods error

shubham9818 — Thu, 10 Feb 2022 15:26:24 GMT

We tried with root user and with test user also, but still getting the above error.

We also did below config change for root user

sudo vi /etc/ssh/sshd_config

Search and change the below lines as below,

PermitRootLogin yes

sudo systemctl restart sshd

For test user, we did below config change

sudo vi /etc/sudoers

added below line

ec2-user ALL=(ALL) ALL

However, with doing the the above changes we are not able to login with both root and test user. Can you please help us on this

Is this related to CDP? Where is your environment?

Without the context we can't help.

Is this a CDP Data Hub?

How did you create the VM?

We created the VM manually through portal. We installed the CDP manager and completed pre-requistes and now we are setting up the cluster through UI, where it is throwing this error. Refer attached screenshot for same. Let me know in case you need more info on this.

Thanks. The context of it is much clearer now.

Could you also provide a screenshot of the Login Credentials page of the wizard?

From the extension of your key file (key.ppk), my guess is that you're using PuTTY to connect to the VMs. Is that correct?

PuTTY uses a different key format than OpenSSH clients. If the above is correct, try converting your key.ppk to OpenSSH format using PuTTYgen (see link below) and try again using the converted file.
