1. Brief description of public key and private key (two-key encryption technology:
Assume that data transmission from data transmitter A to data receiver B (take server a and client B as an example ). B now has a pair of key pairs (public and private keys). B sends the public key

SSH key logon makes centos servers in VPS more secure
As PHP becomes more and more popular, Linux VPS/servers are used more and more, and Linux security issues need to be strengthened. If you have installed DenyHosts and set up email reminders, you may receive several DenyHostsReport messages every day to add the IP address that is used to crack the
SSH key provides a way to communicate with GitHub in such a way that, without entering a password, GitHub can be used as its own remote server for versioning steps to check if SSH keys exist to generate a new SSH key Add
Generating public/private RSA key pair. enter file in which to save the key (/HOME/SCHACON/.SSH/ID_RSA): created directory '/home/schacon/.ssh '. enter passphrase (empty for no passphrase): enter same passphrase again: your identification has been saved In/home/schacon/.ssh
Generate SSH Public keyMost Git servers will choose to use the SSH public key for authorization. Each user in the system must provide a public key for authorization, and none will generate one. The process of generating the public
How Git uses the Generate SSH personal public key to access the Git repository method ( here, for example, the coding platform ):1. Get the SSH protocol addressIn the Project code page click SSH Switch to SSH protocol, get access
First, generate the SSH public key.1. First determine if the machine has created a public key:$ ls ~/.sshThis command is used to check if a id_rsa.pub or id_dsa.pub file already exists, and if the file already exists, the following steps can be omitted and go directly to step 2.If there are no files like Id_rsa and id_
1 if SSH is not installed, then use the following commandsudo apt-get install ssh2 checking the SSH public keyCD ~/.sshSee if it exists. SSH, if present, skim the next step; no, see the next step.3 generating the SSH public key$ ssh
1. Generating the public keyFirst check the native public key:$ CD ~/.sshIf prompted: No such file or directory indicates that you are using Git for the first time. If you are not using it for the first time, do the following to clean up the original SSH key.$ mkdir key_backup$ cp id_rsa* key_backup$ RM id_rsa*To generate
From the gitlab using SSH to pull git code error: The remote end hung up unexpected, after the investigation, is the public key generation may have problems, regenerate, and then add SSH key on the Gitlab, pull the replacement code again.
SSH keys allow to establish a secur
/Etc/ssh/ssh_host_dsa_key. I don't have this file. all the items are in front of the more/etc/ssh/sshd_config file. # try to change it, and restart inetd is invalid. it seems that most of the users do not want to automatically generate the file before the configuration problem. if it fails, check the manual % ssh-keyge
How to generate the SSH public key for GitHub under Windows:1. Install git and open git Bash2. Type the command: ssh-keygen-t rsa-c "[email protected]" "[email protected]" is a github account3. Remind you to enter the name of the key, such as Id_rsa4.
1. See if you already have an SSH key: CD ~/.sshIf there is no key then there will be no such folder, there is a backup to delete2. Survival key:
$ ssh-keygen-t rsa-c "your Mailbox"Press 3 to enter, the password is empty.
Your identification has been saved In/home/t
Approximate step: Generate a pair of keys on the server side, then the public key is saved in the server user directory. Authorized_keys2 under SSH, is a hidden directory. The private key must download the ID_DSA to the client and then generate the. ppk file through Puttygen
the same key to log on to the ssh server.
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.
Note: The public key generally ends with pub, but the file verified by the server is authorized_key.
Method one using the SecureCRT tool1. Open our SECURECRT client and click Tool-->create Public Key.2. Key type We choose an asymmetric type of RSA, follow the prompts next.3, the passphrase settings, when connected to the server need to input, after the settings can be changed by SECURECRT.Next, the key length, 2048.4. The private
