SSH password-free login access via Ssh-keygen and Ssh-copy-id commands under Linux

Always want to transfer their server SSH authentication mode from user name password mode to RSA and DSA authentication protocol, through the release of OpenSSH 4.2, today wrote a configuration process and collected some reference articles on RSA and DSA.Idea Finishing:Has not understood the authentication process in the public key mode, here summarizes the method of making and placing the public key and the secret key. The following assumptions are g

Ssh-keygen + SSH-copy-ID for SSH password-less access in Linux

SSH to the 163 host requires a password, which is inconvenient for some scripts because the password is required, that is, manual intervention is required. The method used previously was to copy the authorized_keys file (I can't remember it, I used it before). Recently, I found a command ssh-copy-ID is very convenient. I tried it and it really worked well. It was recorded below: On 192.168.42.142 1) Run

: $ Password: (enter Password) At this point, if the secret is correct, you can log in. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ In the trust environment, if each remote login, you have to enter a password, feel too wasted time, especially the password is very complex, maintenance of the server more than the case. So there is a normal need: you do not have to enter a password to achieve remote logins. The implementation steps are as follows: 1, local generat

Linux uses Ssh-keygen to implement SSH login without password

its own identity flag "private key" to achieve the purpose of verification, and private key can not be inferred from the public key backwards. This avoids the potential for password leaks caused by network eavesdropping. The client needs to be careful to save its own private key to avoid being stolen by others, and once that happens, the server will need to replace the trusted public key list.2, to achieve the effect:The network topology diagram is as follows: A total of 4 servers, the host nam

[Linux] using Ssh-keygen to generate RSA keys in the Linux CLI

, there may be several reasons why the target server has replaced the public key, and the destination server has replaced the IP address or domain name, causing you to connect to the other host causing the public key to be mismatched; Whatever the reason, you should be wary of establishing a connection.    Note:[1] "challenge" refers to the server using public key encryption data sent to the client, the client uses a paired private key to decrypt the data, the client successfully decrypted after
