Answer / sathyaraj

Using the below command to generate the ssh keys

ssh-keygen -t rsa
cat .ssh/id_rsa.pub | ssh docadm@172.25.64.71 'cat
>> .ssh/authorized_keys'

copy the ssh keys to the other server in the authorized
keys file once the 2048 passphrase has been copied the user
can able to login to the server without password.....

Answer / jani

Step 1: Create Authentication SSH-Kegen Keys on – (192.168.1.1)
First login into server 192.168.1.1 with user tecmint and generate a pair of public keys using following command.
[tecmint@tecmint.com ~]$ ssh-keygen -t rsa

Generating public/private rsa key pair.
Enter file in which to save the key (/home/tecmint/.ssh/id_rsa): [Press enter key]
Created directory '/home/tecmint/.ssh'.
Enter passphrase (empty for no passphrase): [Press enter key]
Enter same passphrase again: [Press enter key]
Your identification has been saved in /home/tecmint/.ssh/id_rsa.
Your public key has been saved in /home/tecmint/.ssh/id_rsa.pub.
The key fingerprint is:
af:bc:25:72:d4:04:65:d9:5d:11:f0:eb:1d:89:50:4c tecmint@tecmint.com
The key's randomart image is:
+--[ RSA 2048]----+
| ..oooE.++|
| o. o.o |
| .. . |
| o . . o|
| S . . + |
| . . . o|
| . o o ..|
| + + |
| +. |
+-----------------+
Step 2: Create .ssh Directory on – 192.168.1.2
Use SSH from server 192.168.1.1 to connect server 192.168.1.2 using sheena as user and create .ssh directory under it, using following command.
[tecmint@tecmint ~]$ ssh sheena@192.168.1.2 mkdir -p .ssh

The authenticity of host '192.168.1.2 (192.168.1.2)' can't be established.
RSA key fingerprint is d6:53:94:43:b3:cf:d7:e2:b0:0d:50:7b:17:32:29:2a.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.1.2' (RSA) to the list of known hosts.
sheena@192.168.1.2's password: [Enter Your Password Here]
Step 3: Upload Generated Public Keys to – 192.168.1.2
Use SSH from server 192.168.1.1 and upload new generated public key (id_rsa.pub) on server 192.168.1.2 under sheena‘s .ssh directory as a file name authorized_keys.
[tecmint@tecmint ~]$ cat .ssh/id_rsa.pub | ssh sheena@192.168.1.2 'cat >> .ssh/authorized_keys'

sheena@192.168.1.2's password: [Enter Your Password Here]
Step 4: Set Permissions on – 192.168.1.2
Due to different SSH versions on servers, we need to set permissions on .ssh directory and authorized_keys file.
[tecmint@tecmint ~]$ ssh sheena@192.168.1.2 "chmod 700 .ssh; chmod 640 .ssh/authorized_keys"

sheena@192.168.1.2's password: [Enter Your Password Here]
Step 5: Login from 192.168.1.1 to 192.168.1.2 Server without Password
From now onwards you can log into 192.168.1.2 as sheena user from server 192.168.1.1 as tecmint user without password.
[tecmint@tecmint ~]$ ssh sheena@192.168.1.2

visit following link to accuratly setup password-less ssh

Answer / teja

open the ssh configration file /etc/ssh/sshd_conf like this
