In this guide I will quickly show you how to enable root logins for Ubuntu. As you may have noticed while installing Ubuntu, you are not prompted to set a root password. This is why you cannot login as root. There are a couple of solutions to overcome this, here are a couple below.
In this easy guide I will be showing you how to use the Linux date command. The date command can be used to see what the date is, what time it is, as-well as set system time (with root/sudo privileges). I will give a few examples as-well as explain the options below since you can format the output to get exactly the information you are looking for as-well as formatted the way you want it.
One of the things you should do when first setting up your new server is changing the SSH port. This is not because it will actually stop a real attacker but because your server will be hammered with automated random login attempts, so the real reason why we will change the default ssh port is so that when the automated attacks can’t even connect to port 22 then usually it just stops and moves on to the next server. If you are using a cloud droplet or VPS that supports snapshots, now is the time to take one just incase you get locked out if something goes terribly wrong (never hurts to be safe!).
