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.

under the user's root directory and compares it to the public key that was sent over. If two keys are consistent, the server encrypts the "challenge" with the public key and sends it to the client software (Putty,xshell, etc.). After a client receives a challenge, it can be decrypted and sent to the server with a local private key, which is quite secure. First, generate the key Because Puttygen generated key problems may occur: "Server refused our key", it is best to use Xshell to generate th
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. The public key and the key are generated first, and by default the public key has a file name that is more than the end of the key. Pub, for example, to manage SSH pub
Configure dual-host SSH trust in LinuxI. Implementation principle using a "public/private key" authentication method for ssh login. A simple explanation of the "Public/Private Key" authentication method is: first, create a pair of public/private keys on the client (Public Key File :~ /. Ssh/id_rsa.pub; private key file :~ /.
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 send it to the server. This method is quite safe.1. Generate a key Because the key generated by puttygen may have a problem: "Server refused our key", it is best to use XShell to
More and more webmasters begin to use independent hosts and VPS. In order to save costs or improve performance, many independent machines and VPS are all unmanaged bare-metal machines, and everything needs to be DIY. At this time, the implementation of security policies is still important. In the following article, I will take CentOS as an example to briefly summarize how to configure Secure SSH access. Linux
I. Implementation Principle Use a public/private key authentication method for ssh login. The following is a simple explanation of the "Public/Private Key" authentication method: First, create a pair of public and private keys on the client (Public Key File :~ /. Ssh/id_rsa.pub; private key file :~ /. Ssh/id_rsa), and then put the public key on the server (~ /.

First, the realization principle SSH logon is done using a method known as "Public key" authentication. A simple explanation for the "public Key" authentication method is: First create a pair of public private keys on the client (public key file: ~/.ssh/id_rsa.pub; private key file: ~/.ssh/id_rsa), and then put the public key on the server (~/.
