How to uninstall and install hdlm packages;How to perform password less authentication once user id set to NP (NO Password)

Not sure what you are referring to hdlm package. Need more clarification.

On passwordless authentication, you need to setup ssh-key authentication and ssh in to the remote server with with the generated public key from the host. Once you are authorised for the first time, it will allow you without password from the subsequent sessions.

HDLM should be your harddisk driver package not sure about it or what we can do with it. Advisable not to play with.

For SSH:

Create SSH keys with the ssh-keygen command on your local machine, you can use the public key to authenticate to a remote server without needing to know the server’s password. This creates a public key (usually named id_rsa.pub) and a private key (usually named id_rsa) in your ~/.ssh directory.

Copy Your Public Key to the Server: You need to copy your public key (id_rsa.pub) to the remote server you want to access.You can use the ssh-copy-id command, or you can manually add the contents of your public key to the ~/.ssh/authorized_keys file on the remote server.
ssh-copy-id your_username@remote_server_ip

Connect to the Server:Once your public key is on the server, you can use the ssh command with the -i option to specify your private key for authentication. ssh -i ~/.ssh/id_rsa your_username@remote_server_ip

Ssh key addition and update we can login as root and perform. My query is if a user set to no password then how that particular user can make ssh connectivity.

Once you add the key to the ssh server

You can login with different user,

ssh USERNAME@IPADDRESS

if you give the username as user1 you will login as user1 instead of root user

Yes still unable to find exact implementation steps for hdlm package.
Ssh key part customer asking to login as root telling the reason user id set to np so We can not able to access.
Any document or article to get knowledge on ssh authentication background.

இந்த ஆவணத்தில், அத்தியாயம் 3 இல், லினக்சில் எப்படி HDLM ஐ நிறுவுவது என்று குறிப்பிட்டுள்ளனர். இந்த HDLM ஒரு தனிஉறிமை மென்பொருள் என்பதால் இதற்கு மேல் இங்கே இந்த HDLM பற்றி உதவ இயலாது.

Ssh key part customer asking to login as root telling the reason user id set to np so We can not able to access.

சிக்கல் தெளிவாக புரியவில்லை, வாடிக்கையாளர் ssh மூலம் root யூசராக கடவு சொல் இல்லாமல் லாகின் செய்ய முயல்கிறார் ஆனால் அவரால் முடியவில்லை ஏனெனில் root யூசருக்கு கடவு சொல் சிஸ்டத்தில் குறிப்பிடப்படவில்லை. இதுதானா சிக்கல்?

Destination user id set to NP. User reaching out us and providing the reason currently user id set to no password so We cannot able to login by the respective user. Kindly login as root and perform the ssh key addition.

NP என்றால் என்ன? ஏன் userid ஐ NP என்று வைத்துள்ளீர்கள்? userid ஐ NP என்று வைத்தால் ஏன் login செய்ய முடியாது?

Kindly login as root and perform the ssh key addition.

யார் root யூசராக லாகின் செய்து ssh key ஐ சேர்க்க வேண்டும், தாங்களா? அல்லது வாடிக்கையாளரா?

உங்கள் வாடிக்கையாளர் ssh செ்யதால் வரும் தகவலை இங்கே பகிர்ந்தால் நல்லது.

NP means No Password. Currently not having that evidence let me share in future. Thanks for your kind reply.
