User Provisioning & SSH Security

Initialize a new system user on the monitoring server and generate cryptographic keys for secure authentication.

1. Create System User​

Provision a new administrative user with a home directory:

create user:

sudo useradd -m -s /bin/bash pandu-hakam

set password:

sudo passwd pandu-hakam

add user

2. Generate SSH Keypair​

Generate an Ed25519 SSH keypair (recommended for security and performance) for the new user:

switch to user and generate key:

sudo -u pandu-hakam ssh-keygen -t ed25519 -N "" -f /home/pandu-hakam/.ssh/id_ed25519

generate ssh key

info

The -N "" flag creates an empty passphrase, while -t ed25519 specifies the modern elliptic curve algorithm.
