AWS ssh key-pair authentication problem #237

Closed rickyb30 closed 2 years ago

rickyb30 commented 2 years ago

Describe the bug

I have created a Panorama VM version 1.10.6 using Terraform. The VM gets created successfully but the SSH authentication using PEM key is not working. It falls back to password authentication. I created the instance manually providing the same key pair and then I was able to SSH successfully.

Expected behavior

SSH authentication should work if Panorama VM is provisioned using Terraform

Current behavior

SSH authentication doesn't work using the syntax ssh -i /path/to/key.pem admin@<ip-address>. It falls back to password authentication and password can only be configured after login to VM using SSH.

Steps to reproduce

  1. Create a Panorama VM using this module https://github.com/PaloAltoNetworks/terraform-aws-vmseries-modules/tree/develop/modules/panorama
  2. Note down the IP address of the VM
  3. Try SSH to the VM using syntax ssh -i /path/to/key.pem admin@<ip-address>

NOTE: I tested both with existing key pair and generate key pair locally, passing the public key to Terraform. It fails in both scenarios.

Context

I'm trying to automate the provisioning of Panorama and Firewalls using Terraform. All the Panorama resources like device groups, security profiles, objects, etc will also be managed using Terraform

Your Environment

Terraform Version is 1.0.6 Panorama Version 1.10.6 Panorama AMI is obtained using AWS Marketplace so it's an official AMI.

What type of ssh key are you using ?

What type of ssh key are you using ?

I have tried both RSA and ed25519. RSA was existing SSH pem key in AWS account I use for other VMs. When that didn't work, I generated ed25519 key pair locally and passed public key to Terraform. That didn't help either.

CORRECTION: Panorama version is 10.1.6

Hey @ulm0 Yeah so I figured it doesn't work if we use instance metadata v2. So in my terraform script, I removed metadata {} block configured in aws_instance resource.

I ran into a same problem and this worked for me: ssh -oHostKeyAlgorithms=+ssh-rsa admin@redacted_ip.1.1.74 -i ./key-pair-name.pem
