How to setting SSH keyless linux system Centos

  Tidak ada komentar
Some time as sysadmin we need to setup the host to login using ssh without typing password
Step 1: Generate RSA key
Generate RSA public and private key by running following command line
[maswachid@ccontrol90 ~]$ ssh-keygen -t rsa
Step 2: Create .ssh directory on target machine
Create .ssh directory by running following command line
[maswachid@ccontrol90 ~]$  ssh [email protected] mkdir -p .ssh
Step 3: Copy the client public key to target machine
Create .ssh directory by running following command line
[maswachid@ccontrol90 ~]$ cat .ssh/id_rsa.pub | ssh [email protected] 'cat >> .ssh/authorized_keys'
Change directory and file privileges
[maswachid@ccontrol90 ~]$ ssh [email protected] "chmod 700 .ssh; chmod 640 .ssh/authorized_keys"
you can enter to target machine via ssh without password now

[maswachid@ccontrol90 ~]$  ssh [email protected]
