How I connect by ssh after configure my vps droplet?

Hello, I create and change the configuration of one user diferent of root, for permissions is like a root. and i create the public key and paste into a ‘/home/<newuser>/.ssh/authorized_keys’ file, I do that exactly:

ssh <newuser>@46.101.46.71 sudo mkdir .ssh sudo chmod 0700 .ssh sudo touch .ssh/authorized_keys sudo chmod 0644 .ssh/authorized_keys sudo chown <newuser> ~/.ssh -R sudo nano .ssh/authorized_keys // i paste the pub key here a goout
// saving file sudo nano /etc/ssh/sshd.config

// in this file I put that Port 222 PubKeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys PermitEmptyPasswords no PermitRootLogin yes // by the moment

// I go out saving file

sudo systemctl restart sshd.service // restart service exit

// now in my local ubuntu

ssh -p 222 <newuser>@46.101.46.71

// the response from server is that: debug1: connect to address 46.101.46.71 port 222: Resource temporarily unavailable // its the same that i treat to connect whit root

ssh -p 222 root@46.101.46.71

Hi there,

I could suggest a couple of things:

  • I would set the permissions to 600 rather than 644 for extra security:
sudo chmod 0600 .ssh/authorized_keys
  • Also if you have a firewall like ufw, make sure to open port 222, as the error that you are getting indicates that your local PC is unable to connect to the Droplet on that port.

  • You can add the -vvv argument to your SSH command for some extra debug information:

ssh -vvv -p 222 <newuser>@46.101.46.71

Let me know how it goes! Regards, Bobby
