Warning: Limiting to a single IP will break our Web SSH Terminal functionality. Otherwise your trusted IP may change and you will not be able to access your server. Please note: Make sure your trusted IP addresses are static. You do this by configuring your firewall to only accept connections from a specific IP to a specific port on your server. Restrict your SSH server to accept the connections from your trusted IP addresses only. The default configuration of the SSH server allows the SSH server to accept connection from any IP address. $ sudo systemctl restart sshd Allow only a single IP to login A password protected SSH server is more vulnerable to the brute force attacks.Īnd set the PasswordAuthentication option to no. Using a public/private key pair to access an SSH server is more secure than using password based authentication. You can enable Password authentication (not recommended) on the Shell Users screen in Webdock. Please note: This is already the installed default in Ubuntu and thus on Webdock Servers. $ ssh -i -p 5333 Using public/private key pair instead of password Logout of your server and re-login using port 5333. Restart the SSH server to apply new configuration. Please note: Every time you change the configuration file, you need to restart the SSH server to apply changes. In case of a Webdock perfect server stack where we have ufw installed, open port 5333. Warning: Changing the SSH port will break our Web SSH Terminal functionality which assumes SSH is on the default port. Please note: Make sure you open the new port before closing the old one. In this guide, we will set up port 5333 for SSH server. Therefore using port 22 for SSH server makes your server, in theory, more vulnerable to hackers. SSH server by default uses port 22 to create connections and everyone knows about it. Webdock cloud Ubuntu instance (18.04 or later).
