So when I was setting my server up with LAMP and Ubuntu I was going through the setup and I disabled remote access. Which I need to connect with file zilla to upload files. So, how do I reanable it?
Even if you disable your ssh service you will still be able to access your droplet via the web console in the control panel. From there you can re-enable ssh in order to connect via Filezilla.
What would I do to re-enable it? Like command wise? enable? Or something else?
You should just need to change back the values in /etc/ssh/sshdconfig that you modified in order to disable it. If you did not make any changes to your sshdconfig you may just need to restart your ssh server with:
service ssh restart
