SSH is the abbreviation for secure Shell, developed by the IETF Network Working Group, and SSH is a security protocol based on the application layer and transport layer. SSH is currently a more reliable protocol that provides security for Telnet sessions and other network services. The use of SSH protocol can effectively prevent the information leakage in the remote management process. SSH was originally a program on a UNIX system, and later expanded quickly to other operating platforms. SSH can
). Although the SSH process can be run through tcpd on inetd, this is completely unnecessary. After the SSH server is started, sshd runs and listens on the default port 22 (you can use # ps-waux | grep sshd to check whether sshd has been correctly run) if SSH is not started through inetd, SSH will remain waiting for connection requests. When a request arrives, the SSH daemon generates a sub-process that processes the connection. However, due to copyright and encryption algorithm restrictions, m

SSH-Server Configuration Guide I. Introduction to SSH SSH (Secure Shell) is a Secure communication protocol provided by an application. It can securely access the server through the SSH protocol, because SSH has a mature public key encryption system, data is encrypted during transmission to prevent malicious tampering, damage, and leakage during transmission. This effectively prevents attacks such as network sniffing and IP spoofing. Ii. install OpenSSH
