Among them, 1, 2, 3 are used for user authentication, while 4 and 5 are used for traffic statistics, 12 and 13 are used for the test phase, and 255 are reserved. 　　 　　 Code Description 1 Access-Request 2 Access-Accept 3 Access-Reject 4 Accounting-Request 5 5Accounting-Response 11 Access-Chall

, the RADIUS server may have three reactions to the new "Access-request": "Access-accept", "Access-reject", or "Access-Challenge ". If all the requirements are valid, radius returns an "Access-accept" response, including the service type (slip, PPP, login user, etc.) and its ancillary information. For example, for slip and PPP, The response includes IP addresses, subnet masks, MTU, and packet filtering information. Data Packet Structure The radius packet is encapsulated in the data field of the

Background: Two-factor authentication (abbreviated as: 2FA, hereinafter referred to as 2FA), where it is the second re-authentication of SSH. 2FA refers to a method of authenticating a user with both a password and a biometric symbol such as a credit card, SMS phone, token, or fingerprint. Through two different authentication procedures, can reduce the risk of password leakage, greatly improve the security of Linux system!First, pre-configuration preparation　　1, to prepare a running OpenSSH serv

As you know, SSH defaults to authentication by default, even if you use an SSH key instead of a password. As a single factor in the way of authentication, once the key leaks, the same will also compromise the security of the server. To address this issue, we will show you how to enable SSH multi-authentication for Ubuntu Server (mfa,multi-factor authentication). When enabled, you need to verify that you have a different authentication factor for your computer or mobile phone when you log on to

give the account and password, and of course the server name. The session object in the mail service is equivalent to the Connection object when the database is connected. MimeMessage: Represents a message class, which is a subclass of messages. It contains the subject (title) of the message, the content, the recipient address, the sender's address, and you can also set up a copy-and-drop, or even an attachment. Transport: Used to send mail. It is the transmitter. Hello world of 4.3 javamail Wh

look at what happens inside Shiro when a verification occurs. We still use the architecture diagram we have seen in the architecture section. Only Authentication-related components on the left are highlighted. Each number represents one step in authentication: Step 2:The program code calls the subject. login method to pass the user's identity and proof to the constructor of the authenticationtoken instance. Step 2:A subject instance, usually a delegatingsubject (or its subclass), transfers t

activation and spam sending. JavaMail can be used. The general process of JAVA mail sending is as follows: 1. Construct a specific class that inherits from javax. mail. Authenticator and override the getPasswordAuthentication () method. This type is used for login verification to ensure that you have the right to send emails to this mailbox. 2. Construct a properties file that stores SMTP server addresses and other parameters. 3. Create a jav
