Secure Meshcentral server on Vultr

@scottalanmiller said in Secure Meshcentral server on Vultr:
Isn't Ubuntu's firewall on by default?
UFW is not installed or enabled by default.
But it just manages iptables, and that is active I believe. but minimally. SSH works without letting anything through. prior to enabling UFW.

Oh, that makes more sense. Firewall is on, firewall manager is absent.

I went the LTS route as I used Vultr's image and its what I know at the moment. No other reason.
What do you mean? You have to intentionally select one of the older versions on Vultr to not be up to date. The top choice is, and has been basically since release day, the current version. They always OFFER out of date versions for people who desire or require that, but they don't promote them in any way.
I missed that. I was just "blinded" once I saw the 18.04. Habit apparently. Really have to stop that.
As for the FW, I didn't know if it was on, off or otherwise so I just set it up. For this single instance, management is not a factor.
@JaredBusch
Thanks for the confirmation on the FW and SSH. Will take that knowledge forward. -

That's what I suspect happens throughout the Ubuntu ecosystem. Somehow they've managed to get "go old" as a habit and everyone just does it and never thinks about the ramifications or what a good default choice is and automatically goes to one that is less ideal.

Oh, that makes more sense. Firewall is on, firewall manager is absent.
UFW is installed by default on Ubuntu but it is not enabled by default. So yeah @JaredBusch said it right

I don’t use Ubuntu. I have no idea wtf it does.
I believe that the Debian image on vultr does not have it pre-installed. But I would have to verify.

Debian doesn't come with it so yeah that is right.

Upgraded from 18.04.2 LTS to current. Accepted default answers for individuals packages during upgrade.
Had issue with MC and the meshcentral-data/meshcentral.db getting set with root:root perms and this caused a few errors with starting MC from meshcentral.service
Changed perms to back to <user>:<user> and all is well. Don't know what would change those perms though? Either way, all is well now.
