How Do I Log in to Ubuntu Machine

Question

A while back, I set up an Ubuntu VM.
During that setup, I downloaded a PEM file.
I was not able to log in with it and gave up in frustration.
I thought I'd try again, but now I cannot even find the PEM file.

How do I get from here, to a working SSH session on the VM?

Answer 1

Hello, @David Rogers !

You'll want to use the Reset password feature under Support + troubleshooting in the portal to reset access to your VM (see instructions below). Once you have your PEM again, one of the more straight forward ways to connect is to use the SSH wizard in the portal which will generate a command for you based on your PEM file location:

Reset Password: What do I do if I lose my PEM file and need to connect to my Ubuntu Virtual Machine?
When you create a Linux virtual machine, you will be warned that Azure does not store the private key used for SSH (a copy of the public key is on the virtual machine). If you've lost the PEM file and need to connect to your virtual machine you can use the Reset Password feature in the portal under Support + troubleshooting.

Thanks for the link about resetting the key. That seemed to work.

Unable to log in with it though. Here is a snippet of some of the commands that I've been running (using Windows subsystem for Linux):

dave@GOLIATH:/mnt/f/zLoad$ chmod 400 dave.pem
dave@GOLIATH:/mnt/f/zLoad$ ssh -i ./dave.pem dave@23.99.182.143
The authenticity of host '23.99.182.143 (23.99.182.143)' can't be established.

Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Thanks @Anonymous ,

I swapped over to bash shell (git) and it worked. That's good enough.

Appreciate the help.
