How-to-use guide for SSH

SSH Authentication Methods
  • Password [Using your server's user's password]
  • Public/Private Key Pair
    • Don't use root to login. Instead create a new user
    Create a new user
    adduser chloe[Can be any name]
    Now add chloe to sudo group
    sudo usermod -aG sudo chloe.
    Since you created a new user, add the public key to that user .ssh folder. It's usually located at /home/chloe. Create a new .ssh folder and create authorized_keys if not exist and paste public key inside.
    # Login into remote server and navigate to /home/chloe
# Create a new .ssh folder
sudo mkdir /home/chloe/.ssh
    # Create file 'authorized_keys'
# Paste client public key inside
# Save it
sudo nano authorized_keys
    Next, change the ownership of the folder to chloe.
    sudo chown -R chloe:chloe /home/chloe

    chown - change ownership
    R - Everything
    chloe:chloe - user:group
    /home/chloe - folder path

    Now, on client side, if you're using new public/private key pair then you have to add them.
    ssh-add /path/to/privatekey [eg. ~/.ssh/id_rso_new]
    [optional]There a possibility that ssh agent inactive. Active by run
    eval `ssh-agent -s`
    That all. Hope the steps simple enough to understand. Peace :)
