OpenSSH SSH-2 private key (old PEM format) on Azure Linux VM
To use an old PEM format SSH-2 private key with OpenSSH on an Azure Linux VM, you can follow these steps:
Connect to your Azure Linux VM using an SSH client, such as PuTTY or the native OpenSSH client.
Copy the private key file (in the old PEM format) to your Azure Linux VM. You can use the
scp
command to securely copy the file from your local machine to the VM. For example:shellscp path/to/private_key.pem username@vm_ip_address:/home/username/
Replace
path/to/private_key.pem
with the actual path to your private key file,username
with your username on the VM, andvm_ip_address
with the IP address or hostname of your Azure Linux VM.On the Azure Linux VM, ensure that the private key file has the correct permissions. Use the
chmod
command to set the appropriate permissions. For example:shellchmod 600 /home/username/private_key.pem
This command sets read and write permissions for the owner of the file and restricts access for others.
Open a terminal session on the Azure Linux VM and use the
ssh
command to connect using the private key. For example:shellssh -i /home/username/private_key.pem username@vm_ip_address
Replace
username
with your username on the VM andvm_ip_address
with the IP address or hostname of your Azure Linux VM.The
-i
option specifies the identity file (private key) to be used for authentication. Make sure to provide the correct path to your private key file.
With these steps, you should be able to use your old PEM format SSH-2 private key to connect to your Azure Linux VM using OpenSSH. Remember to replace the relevant placeholders in the commands with your actual values.
