This section looks at how to use PowerShell to create CloudFront distributions inside AWS. CloudFront is an AWS-provided CDN service that allows you to create a distribution point that points to S3 or Web server, where DNS is automatically resolved to the nearest edge server for optimal access speed.The specific image interface operation can refer tohttp://beanxyz.blog.51cto.com/5570417/1532813Let's see how

When using windows to manage linux servers, SecureCRT, Xshell, and open-source putty are usually used. Most of my work environments use password authentication for logon. Today I learned some SecureCRT key logon methods. Compared with password authentication, using key authentication for Logon has the following advantages:1. Public Key Authentication allows empty

Use SSH config to configure a custom port this way,

About SSHTraditional network service programs, such as ftp,pop,telnet, are inherently insecure because they transmit data, user accounts, and user passwords in clear text on the network, and are vulnerable to attack by a man-in-the-middle attack that would impersonate a real server to receive data from a user to the server. Then impersonate the user to pass the data to the real server.To meet security requirements, the IETF Network Working Group developed Secure Shell (abbreviated as
OpenSSH
OpenSSH is a free open-source implementation of the SSH (Secure Shell) protocol. It uses secure and encrypted network connection tools instead of Telnet, FTP, rlogin, RSH, and rcp tools. OpenSSH supports SSH protocol versions 1.3, 1.5, and 2. Since OpenSSH 2.9, the default protocol is version 2, which uses the RSA key by default.
