ssh keygen linux

On two Linux hosts due to the needs of the environment, often to configure the two host between the password-free login, which will be used to key authentication, that is, the so-called public key authentication. Easy to understand, I'm here to specify two hosts for A and B. If a host wants to be password-free to log on to the B host, the host computer holds the private key, and the B host holds the public key. The two files generated by the

Linux SSH without a password login, linuxssh password login I. ssh schematic: 1. the user name and password are not required for two linux machines to use ssh. Digital signature RSA or DSA is used to complete this operation. 2. Model Analysis Assume that A (192.168.000059)

Method One, Sometimes need to login ssh, each need to enter a password, will be more cumbersome. So set up to use RSA public key authentication way to log on to Linux. First you need to set up/etc/ssh/sshd_config on the server side # Vim/etc/ssh/sshd_config Modify the following two behavior yes. In fact, most of th

A is a local host (that is, the machine used to control other hosts); b is the remote host (that is, the controlled machine server), if the IP is 172.24.253.2; A and B systems are linux on a command: # ssh-keygen-t RSA (three consecutive returns, that is, the public and private keys are generated locally, no password is set) #

Linux uses ssh password-free remote login to another machine. 1. use the ssh-keygen command under your own machine (master) to create a public key, if you use ssh-keygen-trsa to create a directory, the program will ask you about t
