Reference URL: https://www.gnu.org/software/screen/manual/screen.html1 backgroundAs a system administrator, we often need SSH or telent telnet to a Linux server and often run tasks that take a long time to complete, such as system backup, FTP transfer, compilation, and so on. Usually we open a remote terminal window for each of these tasks because they take too long to execute. Must wait for them to complete, during this period cannot shut down the window or disconnects, otherwise this task will

mentioned here, and more information is available in the standard SLES 8 documentation, which can be found on the SLES 8 release CD. Why use a serial connection for installation? Some (not all) System P models are equipped with supported video adapters. Supported video adapters include GXP-120, GXP-130, and GXP-135, but GXP-135 require a CRT with a digital video connector. For other System p models, the serial connection is used for installation through approved terminal clients. Approved ter

. Console, that is, the console, is the system output management information of the character output device, these management information is generated by the kernel, such as System log, alarm information. The default console for Linux is the keyboard and monitor, while some old-fashioned sun, HP, IBM servers use serial port-connected text Terminal[1] (character terminals, such as the famous Dec VT100) as consoles, which is the way it will be introduce

As with all shells, when you need to visualize data, the upper limit is limited. such as Pssh, OSH, fabric and other tools, management returned data methods are not the same, they have different ways to aggregate output fr

many kinds of machines, but how do people use these machines? They are connected to these machines by means of dumb terminals, which are connected to the central computer (computer) by a machine consisting of a keyboard, a display, and enough electronics (electronic components). On these terminals, the user can knock the character (Teletypy), which is the string ' tty ' representing the terminal equipment file, and the ' Getty ' Command's name history. You might ask, where are these things now

1. Preparation The least secure method is to run only one or two services on the host. Using a machine is much safer than using a machine with all the rights, because it can be isolated and easy to find the problem. In short: Run some of your most essential services on your machine. Consider removing the keyboard, screen, so that you can avoid using X11 and knowing the command line to test in an isolated, trusted network segment. Be clear about what kind of results your system and hardware conf
