By using Ssh-keygen to generate the public key, a new channel geek is established between the two machines.Suppose the local machine is the client and the remote machine is the server.1. Use Ssh-keygen to generate RSA keygen (this will overwrite the previously generated ~/.
All operations are OK on the client side.The general idea is as follows: On the client side, generate a public-private key pair that uploads the public key to the ~/.ssh/of the specified user on the server (for example, a)Modify the next file, the directory permissions are OK, so you can from the client to the server t

First we need to create SSH key, how to create SSH key?? Go to the directory where our local version is located, execute the following statement: "Ssh-keygen-t rsa-c" registers a GitHub mailbox, and then generates the following files in the user's home directory: (note that
receives the request, first look for your public key in the user root directory of the server and compare it to the public key you sent over. If two keys are identical, the server encrypts the "Challenge" (challenge) with the public key and sends it to the client software. Thus avoiding being "man-in-the-middle" attacks.
On the server side,

This takes the username Zhangsan as an example.
Because of personal habits, I changed the user Zhangsan default directory, in the process of using the key to log in, always prompted to enter the user password, and/var/log/secure also did not have any information,Later in the/etc/passwd the default directory changed
I didn't care much about using SSH before. After the installation is not how to configure. Login is also directly with the password. This is not too safe, in fact, it is more troublesome, because each time you have to enter a password. If the public key of the private key is used to authenticate. You can log in directly (provided that the private

When SSH logs on to the remote host in Linux, the public private key authentication method can be done.① Environment Description: Two Linux hosts, host1:192.168.5.1,host2:192.168.5.10. Now set up on host1 and then go to log on to the HOST2 host.② SSH service is turned on automatically by default. You can view the next netstat–nlutp|grepssh in LinuxThis shows that
server makes a comparison of the information returned by the client. If the comparison succeeds, the authentication succeeds and the client can log on. If the comparison fails, the authentication fails, and the login verification is continued with other means, such as password verification.

In linux, the public/private key is generated to allow putty (ssh) to log on automatically (and ssh to log on automatically using the key in linux). Method 1: Use puttygen.exe. Step 1: generate a key to run puttygen.exe, select th
When you use https://to submit a private item on GitHub, you need to enter your account number and password every time.Like my own notebook, I don't want to enter these every time I push.Then use SSH, which needs to add the notebook's SSH key to the GitHub account.①ssh-keygen-t rsa-c "[Email protected]"Enter an e-mail

When we use a Linux host, we typically produce two forms of key, one that is generated on a Linux host and then distributed with the private key, and one that is generated with the SSH tool and then uploads the public key to the server. The following three scenarios require a key
