ssh authentication methods

I. Overview 1, is to allow two Linux machines to use SSH between the user name and password is not required. Digital signature RSA or DSA is used to complete this operation. 2. Model Analysis Assuming that a (192.168.20.59) is a client machine, B (192.168.20.60) is the target machine;The purpose to be achieved:A machine SSH login B machine does not need to enter a password;Encryption method to select RSA|DS

Cvs (Concurrent Version System) is a widely used Version control tool. Although its functions are not as powerful as Perforce and Subversion, it is widely used in various software projects because it is easy to configure and use, and has been released for a long time. First, install FreeBSD and apply security patches. This step is very simple. Download a FreeBSD (the upcoming 5.2-RELEASE is a good choice. This version may already be available for download at the time of this article) mini iso bu

When we use SSH authentication mode, using Jgit to pull the replacement code from the remote repository (for example, GitHub), obviously the local host's SSH public key key has been added to the Remote Repository authorization key list, but when using the SSH authentication

The so-called key Authentication actually uses a pair of encryption strings. One is called a public key, which can be seen by anyone for encryption. The other is called a private key ), only the owner can see it for decryption. Ciphertext encrypted by the public key can be easily decrypted using the key, but it is very difficult to guess the key based on the public key. Ssh key

It is difficult to use pserver-based Remote Authentication in CVS. You need to define the server and user group, user name, and password, Common login formats are as follows:CVS-D: pserver: cvs_user_name@cvs.server.address:/path/to/cvsroot LoginExample:CVS-D: pserver: cvs@samba.org:/cvsroot Login It is not safe, so it is generally used as an anonymous read-only CVS access method. In terms of security, it is better to pass the local account
