However, this isn’t the best way to do things. If you have multiple machines and want to copy your key from one machine to another, then there are better ways of doing that than copying the key files over. This ... Read More

Overview We’ll go through some of the features available on the CPU installed on our computer’s motherboard. We’ll briefly look at the concept of virtual file systems before we dive into the details of the topic. Afterward, we’ll discuss the flags obtained from the /proc/cpuinfo virtual directory for different CPU manufacturers such Intel, AMD, and Arm. Virtual Files A virtual file system (VFS) is an abstraction layer that allows us to treat files as if they were stored on a disk drive. The VFS provides a way to access data without having to know where it actually resides. For example, ... Read More

Abstract It's challenging to envision what would happen if you couldn't control your computer remotely because remote access to computers has long been necessary. The best way to connect to a remote machine is by SSH for Linux-based machines. The SSH client application can be used to log into a distant computer or server and run commands on that computer. When a command is supplied, it is executed instead of a login shell on the remote host or server. Users frequently need to work with distant systems. which requires them to log into the remote server, carry out specific actions, ... Read More
