JumpServer manages Linux-related resources, but current security requirements do not allow root users to log in directly. How to log in as a normal user first and then switch to the root user when setting up a bastion host?

In the "Connection Mode" item, if the remote host can be directly connected by the teleport server, you can select the "Direct Connection" mode, for example, the remote host and the teleport server are in the same LAN, or the remote host is a cloud server with a remote connection port open.

By providing a series of dynamic link libraries and two sets of programming interfaces (Service Programming Interface and Application Programming Interface), the services provided by the system are separated from the authentication methods of the services, so that different authentication methods can be flexibly configured for different services as needed without changing the service programs.

Take the private deployment SSH tool as an example, open the SSH tool on the user's local computer (SecureCRT is used as an example here), and click Quick Connect; enter the "IP" private deployment transit server IP (private deployment transit is together with the portal server by default), "Port" 8022 (the transit server firewall must open port 8022), "Username" please fill in your Xingyun Butler account (user admin is used as an example here), "Password" please fill in the password corresponding to your Xingyun Butler account;

If you are connecting directly in a terminal such as Linux, please refer to the following command format to fill in the form, assuming that the Xingyun Manager portal address is yun.baoleiji.com, and the Xingyun Manager user is the domain user bill@cloud.com to log in to the Xingyun Manager portal

Using this plugin, you can replace vim in many cases to directly modify and debug the code on the server remotely. It also has code highlighting and completion functions, just like using VScode locally, without having to repeatedly configure vim plugins on the server side.

Definition and Principle of Honeypot

As the name implies, a honeypot is a "bait" designed to attract and capture attackers. It usually simulates a vulnerable system or service to lure attackers to come and try to attack. By observing and analyzing the attacker's behavior, we can obtain the attacker's intelligence and attack mode, providing important basis for subsequent defense measures.

Application scenarios of honeypots

Honeypot technology can be widely used in various network environments, such as corporate intranets, government agency networks, school networks, etc. It can not only be used to defend against external attacks, but also for internal security audits and risk assessments. In addition, honeypots can also be used to study new attack methods and defense technologies, providing important support for the development of network security.

How to set up and manage a honeypot

Setting up and managing a honeypot requires certain skills and experience. First, we need to select the appropriate honeypot type and configuration, and select the simulated operating system, service type, etc. according to actual needs. Secondly, we need to configure the logging function of the honeypot to collect and analyze the attacker's behavior data. In addition, we also need to regularly update the configuration and patches of the honeypot to prevent advanced attackers from exploiting vulnerabilities to bypass our traps.
