Step 4: Install the extension package. Go to the official website to download the Vbox. Remember to make it consistent with your Vbox version. If it is wrong, stop shouting.
Now you can open the Vbox manager you installed and add the downloaded extension package to the global variable extension.

RemoteBox is a good application. RemoteBox is a graphical tool used to manage remote servers or local VirtualBox virtual machines. Although the management interface of VirtualBox is sufficient to meet most of the usage requirements, it is a pity that it does not provide the function of Remotely Managing virtual machines. That is to say, as long as the virtual machine is shut down, the user will not be able
more advanced authentication features, then please read on. How the RSA/DSA key works The following is a general overview of how the RSA/DSA key works. Let's start with an imaginary scenario, assuming that we want to use RSA authentication to allow a local Linux workstation (called Localbox) to open a remote shell on Remotebox, Remotebox is a machine from our ISP. At this point, when we try to connect to
, we will discuss in detail how to correctly use RSA and DSA authentication protocols, so that we do not risk any unnecessary security risks. In my next article, I'll show you how to use ssh-agent to hide a private key that has been decrypted, as well as an introduction to keychain, which is the front end of Ssh-agent and provides many conveniences without sacrificing security. If you've always wanted to master OpenSSH's more advanced authentication features, then please read on.How the RSA/DSA
Because I often deal with Linux servers at work, I used an SSH key pair-based automatic login to avoid Frequent password input during switching between servers. The following describes the principle of RSA/DSA keys.
Let's start with a hypothetical scenario, assuming that we want to use RSA Authentication to allow a local computer (called localbox) to open a remote shell on remotebox, remotebox is a machine

Step 3: create a secure channel to your POP3 server
Now let's assume that the user's local system is named localbox, and the host name of the target POP3 mailbox of the competent user is remotebox. The next step is to create an encrypted SSH channel between port 110 (Standard port for POP3 connection) on the remote
