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
Configure remote Linux Server SSH key authentication for automatic logon in Mac OS X1. Create a public key on the local machine
Open the omnipotent terminal, execute the following command, ignore all output, and press ENTER happily.
ssh-keygen -t rsa -C 'your email@domain.com'
-T specifies the
RSA and DSA algorithms. In recent years, DSA has become less secure, so it is recommended to use a key based on the RSA algorithm to establish an SSH secure connection.The basic use of SSH key is to randomly generate a private key
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

If you do not have SSH and rsync installed, you can install it using the command below.

, this article will start the SecureCRT key Logon Setting Process.1. Generate a key on SecureCRT.Next stepThere are two encryption methods: DSA and RSA, which are supported in OpenSSL. You can select either of them. Next StepYou can enter a password here (the password is required for Logon), or leave it blank.This is the password length. The default value is 1024
The recent configuration of the GitHub SSH key, the search for a large amount of data found GitHub official has a related tutorial ... Translate the official tutorials here to deepen your impressionsOriginal link: https://help.github.com/categories/ssh/Generating an SSH key
Step 1: generate a keyRun puttygen.exe and select the required key type (parameters) and length (bits ). Putty uses the SSH1 protocol by default. The default length is 1024,
We will use the SSH1 protocol for the time being. We will discuss the differences between the SSH2 protocol and the SSH1 protocol.

As a Linux administrator, logging on to multiple Linux servers for remote operations is part of the daily work. But with the increase of the server, each login, the system will prompt to enter the user name and password, frequent input user name and password is a very annoying thing. Some people may say that you can use some of the client tools, such as: SECURECRT, and so on, it is very convenient for using these software, but these software is not expensive commercial software is attached to a

Recently, a project needs to use a server as a dedicated deployment server, encountered some problems in the implementation process, as follows:1. The SSH default port of the server and the SSH port of the project Git repository are inconsistent 2. Deployment requires SSH key provided by the project and cannot use the
SSH login verification with RSA key pairThe advantage of using RSA key pair to verify SSH is 1) no password 2) is more secure than password authentication; The disadvantage is 1) The first configuration is a bit of a hassle. 2) The private key needs to be carefully saved. An
