SSH key authentication for Linux systems

in the on Linux clients Build ssh keys for RSA

Id_rsa is the key

Id_rsa.pub is the public key

[email protected]xuegod128~]# ssh-keygen-t RSA

Generating public/private RSA key pair.

Enter file in which to save the key (/ROOT/.SSH/ID_RSA):

Enter passphrase (empty for no passphrase):

Enter same Passphrase again:

Your identification has been saved In/root/.ssh/id_rsa.

Your public key has been saved in/root/.ssh/id_rsa.pub.

The key fingerprint is:

e2:19:f2:b4:e3:90:b6:36:08:70:1c:1d:2d:67:53:16 [email protected] localhost . CN

The key ' s Randomart image is:

+--[RSA 2048]----+

| .. O. E. |

| .         o =. |

| . .         + . |

|. o |

|.. . + S |

|. * =         |

| . .+ *          |

| ..         o+. |

| ....          |

Then send the client public key to the Linux server (192.168.31.129)

[Email protected] ~]# ssh-copy-id-i/root/.ssh/id_rsa.pub 192.168.31.129

[email protected] ' s password:

Now try logging to the machine, with "ssh ' 192.168.31.129 '", and check in:

. Ssh/authorized_keys

To make sure we haven ' t added extra keys so you weren ' t expecting.

Test Client logon Status

[[email protected] ~]# ssh 192.168.31.129

[[Email protected] ~]# exit
