When we ssh to a Linux host, we need to enter the account password. In order to password-free login, we usually use SSH key authentication method. The principle is probably as follows:We want to log in from a host SSH to Host B, usually we generate a key pair on the a host,
Git SSH Key settings and gitsshkey settingsI wanted to write an article about SSH, mainly about Git SSH. However, I found that many articles have been well written. You can refer to the "references" below ".Here is a simple record (for Mac), Git SSH
SSH public key verification
It is not safe to log on to the server using the username and password. The SSH public key is used to verify that this method can effectively solve the login server and secure login server features:Objective: to log on to the Server by using Client password-free sshSSH supports multiple logo
SSH login with no password to use the public and private keys. Linux can be used to generate a public/private key pair with Ssh-keygen, below I take CentOS as an example.There is machine A (192.168.1.155), B (192.168.1.181). Now want to a through SSH password-free login to B.First, take the root account login as an exa

First, IntroductionAnsible is strong in the playbooks, but in order to use the playbooks very well, we must first have some foundation. such as: How to write a one-time script command? How do you know which modules are available? How are each module used? such asWith this article, you can learn how to use one-time commands and some modules.After installing Ansible, to get started, you also need to create a list of controlled hosts. Default Read/etc/ansible/hosts, if the file does not exist, you
We have a gitlab in our daily work and some of our own projects on GitHub. This leads us to configure different ssh-key to correspond to different environments. Let's take a look at the specific operation: 1, generate a company Ssh-key $ ssh-keygen-t rsa-c "[email protecte
Many of the online SSH-free password use git commands do not take into account the situation of multiple public key keys, here to collect and tidy up the management of multiple SSH public key keys.

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

You can add multiple SSH keys in the background of GitHub, but the same SSH keys can only be added to an account ("Key is already" when added). The reason is easy to think that SSH public key use is equivalent to the user name password, it is not possible to two different ac
The role of SSH keyWhen we use SSH to log in to the server, it is common to log in using the username/password method.You can also use SSH key to implement password-free login, which is generally used in this way by the GIT server more.Generate SSH
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.

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
