Currently when I login to SSH the name is root@my-initial-droplet-name, how to change it to root@new-droplet-name?
Thanks

Add a new user, with sudo permissions
- copy your current
root@ssh key pair some place safe. - generate a new key par for your non-root user with
ssh-keygen- (keep it to a different place to your root keys). - create another user on your droplet call him
mrwww. - You’ll need a way for your new user to become
root.sudoordoasare god for this.
- as root grant your new user access with
echo 'mrwww ALL=(ALL) ALL' >> /etc/sudoers
- copy the
.pubfrom the new key pair into~mrwww/.ssh/authorized_keys, and chmod 0400 it. - test your key will let you in with
ssh -i /path/to/new-id_rsa mrwww@yourdroplet
- test that you can do stuff as root
sudo touch /tmp/whatls -l /tmp/what# this should show the file created byroot.
Hi, thanks for answering, but it seems your guide is to create new user, what I want is changing the name after @ on SSH command line, from root@my-initial-droplet-name to root@new-droplet-name.
Changing droplet name doesn’t change this SSH address. I already deleted the login detail on my winscp and recreate it, but doesn’t change anything either. Thanks
For most distros you will use hostnamectl on the command line.
