问题
I'm using macos and required to connect to an azure server via ssh. The previous system admin provided me with a .ppk file which he was using to open ssh connection via putty. I want to connect to the server via ssh shell, I believe I need to convert the .ppk file to .pem but the when I run the below command it's prompting me for passphrase which I don't have.
puttygen server.ppk -O private-openssh -o server.pem
I'm thinking of connecting to the server from a windows pc and disable the .ppk file requirement on the server so that I can connect to the server just with username and password. How can I do that? Or does anybody know other alternative to connect to the server via ssh(creating a new ssh user account in azure portal?)
PS: We will be moving AWS soon so these servers will be decommissioned. Hence I'm not worried about the security.

According to your scenario, you could create a new ssh key pair and add id_ras.pub to your VM. Then, you could use the new key to login your VM.
1.Create a new ssh key pair with ssh-keygen.
2.Add pub key to your VM, you could do it on Azure Portal.
Note:It does not overwrite original keys.
3.You could use new private key to login your VM. If you want, you could enable password login. Modify /etc/ssh/sshd_config.
PasswordAuthentication yes
