Creating SSH2 RSA key; this may take some time ... 2048 SHA256:WubjfWd5Qa4kW3WxGg5y4AcCItRBnSMkWqG1yEQDnnM root@Linx (RSA)

It looks like you are generating a new SSH2 RSA key on a Linux machine with a 2048-bit key length and SHA256 hashing algorithm. This process may take some time depending on the speed of your machine. Once the key is generated, it will be associated with the username "root" on the machine named "Linx". This key can be used for secure remote access to the machine via SSH.
