Hello Friends,
Hope You all are doing well 🙂
Once again “Happy Ramdan Sahrif to All “
Today I am gonna share with you that “How can we access remote machine without password” ??
In this scenario I have a machine linux.sahil.com that having ip 192.168.11.10 and other one is my remote machine is zen.sahil.com having ip is 192.168.11. 98
I have to access 192.168.11.98 machine from 192.168.11.10 without using Password.
Lets start 🙂
Generate Key :-
[root@linux ~]# ssh-keygen -t dsa
Generating public/private dsa key pair.
Enter file in which to save the key (/root/.ssh/id_dsa): Enter passphrase (empty for no passphrase): Press Enter
Enter same passphrase again: Press Enter
Your identification has been saved in /root/.ssh/id_dsa.
Your public key has been saved in /root/.ssh/id_dsa.pub.
The key fingerprint is:
31:e0:70:ab:de:a8:e7:b9:af:c0:80:c9:a0:29:83:09 root@linux.sahil.com
The key’s randomart image is:
+–[ DSA 1024]—-+
| . o |
| + o |
|E o o |
|B+ . o |
|@. . S |
|.+ . o |
| o o . |
| o.. |
| .o=+. |
+—————–+
Copy the key to remote machine for Password less access:-
[root@linux ~]# ssh-copy-id -i ~/.ssh/id_dsa.pub 192.168.11.98
“Thank You !! ”
root@192.168.11.98’s password: Give your remote password for only one time
Now try logging into the machine, with “ssh ‘192.168.11.98’”, and check in:
.ssh/authorized_keys <———- key store here
to make sure we haven’t added extra keys that you weren’t expecting.
Now Try to access remote machine :-
root@linux ~]# ssh 192.168.11.98
“Thank You ji !!”
