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

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

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.

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.①

Test Environment: secureCRT client is used in windows, and two redhat 6.3 virtual machines (linuxA and B, 192.168.1.2/3) are deployed ). The VM and the host use a bridging network and are in the same LAN.
Test process:
Note: The public key generally ends with pub, but the file verified by the server is authorized_key.
transfer the content of pub to authorized_key. Pub files are useless.1. Use CRT to generate a key pair and upload the public key to linuxA. After successful login, the Public Key in the cpoyA machine is sent to machine B, so that the CRT can automatically log on to machine B and verify that the public
receiving the request, the server first looks for a common key 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 pr
, if it succeeds, we will be allowed to log on, and a remotebox shell will prompt you to welcome us.
Although the default SSH authentication method is quite secure, RSA and DSA authentication creates some new potential opportunities for us. Unlike SSH Secure Password Authentication, RSA Authentication requires some initial configurations. We only need to perform these initial configuration steps once. Afte
