ObjectiveWhether it is the personal VPS or the enterprise allows public access to the server, if the open 22-Port SSH Password login authentication method, by many hacker violence to guess the broken chrysanthemum can also be a frequent tragedy. Enterprises can be restricted through firewalls, ordinary users may also be modified by 22 port and strengthen the weak password, such as protection, but the relatively safe and simple scenario is to let

Every time you log in to Linux need to enter a large number of passwords (sometimes wait a long time to enter the password, the article finally has a solution), password set too short, security is not high, long hard to remember and input trouble.Using a key to log in can not only eliminate the steps of password entry, but also improve the security of the server.1.

SSH does not have password logon to use the public key and private key. Linux can be used to generate a public/private key pair with Ssh-keygen.There is a machine a,b (192.168.0.32). Now want a password to login to B via

If you have used a Linux operating system VPS or other server, you may often be prompted to log in at the number of times you have failed to log in.This logging failure record is actually the attacker using a script to automatically scan the entire network IP and then filter and test, the final script will use the built-in cipher group to try to log on to open 22-Port Linux server.Of course, if the login success means that your server is hacked, in addition to the search for valuable content in

a pair of keys (private key + public key) to place the public key on the server registration. When a user logs on to a server from a client, the server receives a security authentication request using the key (that is, the public key registered on the server), the server is

under the root directory of the user, and then compares it with the public key sent. If the two keys are consistent, the server uses the public key to encrypt the question and send it to the client software (putty, xshell, etc ). After receiving the question, the client can decrypt it with a local private key and then

The important reason for writing this article is that many people feel unable to share a key pair directly with the Linux system when they use tortoisegit under WindowsThe reason is that tortoisegit default to use the Putty format of the Ssh-key, and the Linux system Ssh-
