Recently, I have been studying how to automatically log on to linux servers. This article describes how to automatically log on to the ssh key. Update: 2014.3.94: 21PM. after finishing this article last night, I found a complete description of ssh authentication on IBM's Internet. Sad .. Using rs
Recently, I have been studying how to automatically log on to linux
Method 1:
In the following example, ssky-keygen and SSH-copy-ID can be used to log on to a remote Linux host without a password.Ssh-keygen creates the public key and key.Ssh-copy-ID copies the public key of the local host to the authorized_keys file of the remote host.The SSH-copy-ID will also be sent to the user home
Because I often deal with Linux servers at work, I used an SSH key pair-based automatic login to avoid Frequent password input during switching between servers. The following describes the principle of RSA/DSA keys.
Let's start with a hypothetical scenario, assuming that we want to use RSA Authentication to allow a local computer (called localbox) to open a remote shell on remotebox, remotebox is a machine
First, installation environment1. Native system: Windows ten Pro (64-bit)2. Git version: Git-2.11.0-64-bit.exe (64-bit)Second, git installationGo to the official website after downloading the next step to complete the installation, such as:See if the configuration is in the system environment variable after installationThen right-click on the desktop, choose Git bash here, and enter the following code:git --version #验证git是否安装成功,输出版本号就代表安装成功Such as: The installation is complete with the configura
I. Public Key Authentication
1. principle: first, the user generates a pair of keys, and then stores the public key in the user directory of the SSH server. in the authorized_key file in the SSH subdirectory (/root /. SSH/authorized_key ). the private
: "Git remote add origin [email Protected]:mockingbirds/gitlearn.git", Note that the mockingbirds here is my username for GitHub, Gitlearn.git is the name of the remote repository, and we need to change all of them to be the same as yourself.Note that we need to commit the local file to the local repository first, that is, the modified file git add filename and git commit need to be linked to the remote repository first. As follows:This completes the local warehouse and Remote Warehouse Associat
Use the SSH Public Key for password-free Login
SSH password-less logon requires the public key and private key. In Linux, ssh-keygen can be used to generate public/private key pairs. T
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 password
-keygen -i -f Identity.pub >> /home/subsir/.ssh/authorized_keys# chmod 600 /home/subsir/.ssh/authorized_keys
5. Set the logon mode to PublicKey in SecureCRT, and select the created Identity file as the private key.
6. Restart the SSH server on the Ubuntu server.
#sudo /etc/init.d/s
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 SSH
SSH key-based logon and password-disabled logon practices
Preface
Whether it's a personal VPS or a server that enterprises allow access to the public network, if the SSH password authentication method for port 22 is enabled, it may also happen frequently when it is cracked by many hackers. Enterprises can use firewalls for restrictions. Common users may also use

Because the company team uses GITLAB to host the code, while the individual on Github also has some code warehouse, the company mailbox and personal mailbox is different, the resulting SSH key is also different, which caused the conflict, the article provides solutions to such problems: how to use the same on a machine Github and Gitlab services?1.
