Two general methods to help you achieve remote server control

The most common components that make up a computer are the monitor, keyboard, and mouse, and you can start clicking and printing. For a local server, these are possible, whether in the office or in the data center. But in recent years, servers are gradually beginning to change locations: on the other side of a building, another building, another city, and sometimes even another country. Therefore, it is very important to be able to efficiently manage the server remotely.

The method of remotely managing a server varies depending on the server, operating system, and available software, but there are many ways that most servers can be used. According to the professional, the two most common methods are remote command line access and network control panels.

Remote Command Line

Many years ago, Telnet was the most commonly used protocol for connecting a terminal to a server. It is standardized by the Internet Engineering Task Force (IETF) and is supported by almost all operating systems. Unfortunately, Telnet is not very secure. As servers are gradually migrating from within the enterprise to the rest of the country, network security issues are spreading from campus to the world, and security risks are rising.

SSH was developed as an alternative to Telnet. Currently, most UNIX and Linux servers use the SSH protocol as the default. In addition, Windows system administrators can install SSH versions very smoothly on Windows Server 2008.

Using the SSH protocol, network transactions are verified using a public key cryptosystem. Encrypting user passwords ensures that hackers cannot intercept network transactions and steal sensitive information.

The most widely used SSH server and BSD and Linux client are OpenSSH. It is free open source software and can be used in most software libraries. Use a regular UNIX username and password to log in and access real-time server real-time systems. Users who are authenticated can even log in as root and perform system tasks as if they were running on the server.

Since the protocol is hierarchical, the SSH protocol can be used for the verification and delivery of file transfers. SCP (Secure Copy) and SFTP (SSH File Transfer Protocol) are two such protocols.

On unmanaged Linux or Unix remote dedicated servers, SSH is the most basic. System administrators can accomplish many tasks from the network control panel, and more advanced features and troubleshooting require shell access.

Network Control Panel

The Network Control Panel is an application that can act as a real server outpost. Depending on the type of software, the Control Panel can be used for system management, virtual private server management, shared hosting site management, and individual user access. Most control panels on the market are proprietary and require a commercial license, but there are also some free open source panels that users can download and use for free. Other websites can also create their own custom control panels for their server users.

Some control panels need to change the operating system or software on the server in order to perform functions correctly. In some cases the Control Panel can compile and install custom configurations of freeware. Others use the actual shell command line to perform functions. The reason is that for some control panels, it is difficult to uninstall without affecting the website. So it's important to make sure your panel is up to you before creating a live site.

The more common control panels are: cPanel/WHM, Parallels Plesk, H-Sphere and open source Webmin/Virtualmin.

Server Monitoring - When the server is remotely set up, it is important to have some sort of remote monitoring system to issue an alert notification when the server encounters a problem. These tools and services may be as simple as notifications such as Apache are terminated or they can provide complex load balancing, network security, and real-time data such as website usage.

KVM is a remote KVM device that can be used to access a server. It requires the data center administrator to configure the necessary hardware, but once the connection is successful, the user has a virtual keyboard and display to directly manage and repair their servers. Websites usually provide this extension service and charge for the time of use.

Reboot Switch - This tool allows the server administrator to control the power switch or power supply on the computer. If the server is completely unresponsive, the administrator can remotely reboot the power without contacting the data center staff.

Overall Control

The work of a dedicated server system administrator is cumbersome. Overall control of the server gives you more freedom and flexibility in managing your servers. It also gives the administrator greater responsibility. The root access capabilities of SSH can be fully applied to the server. Even control panel accounts can access highly corrupted administrative commands. So make sure you know what you are going to do before you decide to make a change. With sufficient preparation, management of the server will become easier and more efficient.
