Question

Everything in my droplet uninstalled?

Posted April 24, 2020 469 views
Ubuntu 18.04

I ssh'ed into my droplet and everything was… green? the directories are usually blue and I have a ruby on rails API on there. When I try to run it, it says that rails isn’t installed…But I ran it yesterday… and the day before… When I ssh into my other droplet it doesn’t have this issue so… I don’t know what to do. This happened before so I just destroyed that droplet and got a new one but now it’s happening again and I dont’ want to keep getting new droplets so…I really don’t understand whats going on :(

Hello,

This sounds like a command is being executed which causes the issue for you.
There are a few things that I would recommend checking:

  • Check the list of last logged in users. You can do that with this command:
  • last

The output will look like this:

root     pts/0        USER_IP     Fri Apr 24 15:11   still logged in
root     pts/0        USER_IP     Thu Apr 23 17:23 - 20:49  (03:26)
root     pts/0        USER_IP     Wed Apr 22 16:25 - 20:12  (03:47)
root     pts/0        USER_IP     Wed Apr 22 08:40 - 11:19  (02:39)

That way you will be able to tell if someone from anther IP address is accessing your Droplet.

  • Check the last commands that were executed on the Droplet:
  • history

That way you will be able to see which command caused the problem

  • Enable backups for your Droplet, that way you will be able to restore to a working backup rather than starting from scratch every time there is a problem

  • Configure your firewall so that you could restrict some of the access to your Droplet. You can take a look at this tutorial here on how to do that:

https://www.digitalocean.com/community/tutorials/how-to-set-up-a-firewall-with-ufw-on-ubuntu-18-04

  • Use only SSH Key-based authentication rather than passwords

Let me know how it goes!

Bobby

UFW, or Uncomplicated Firewall, is an interface to iptables that is geared towards simplifying the process of configuring a firewall on Linux servers. In this guide, you'll learn how to set up a firewall with UFW on Ubuntu 18.04.
  • I thought it was that too! But I can’t think of any command that I ran that would keep running besides rails s. I checked the last and history and it’s just a bunch of “cd” and “rails s -b” I already have my ufw firewall set up too. I run my rails server on port 5000 but I checked and nothing is running on that. So I really have no idea what to do now
