Not sure how, but I broke my server during setup
Completely new to this, and new to Ubuntu so I'm pretty lost.
I was going through the tutorial to set up a server and it said to set up SSH. So, I followed the steps exactly as it said then I opened a new tab and went to log in with my new user but the symbols in the console went crazy and it wouldn't let me type.
I closed the tabs (all tabs it was active in) and when I came back it was still messed up. So, I did a power cycle. Then it was fine so I logged in with the new user I created (with all admin rights) and I typed in what it told me to type to make sure I was validated. 'ssh -p port# username@ip' but I get some errors when I do that. Then I went to install LAMP but i get errors with that. So I tried to check the ipconfig with what the tutorial said to type and it didn't work (finally googled it and found you can use 'ifconfig' which worked.
Anyway, I typed that into a new tab and it eventually timed out instead of loading anything. Now when I type my domain in (which I know I set up correctly because I've done it before with a different domain) it just says:
The server at 'domain' can't be found, because the DNS lookup failed. DNS is the network service that translates a website's name to its Internet address. This error is most often caused by having no connection to the Internet or a misconfigured network. It can also be caused by an unresponsive DNS server or a firewall preventing Google Chrome from accessing the network.
Does anyone know what went wrong, or know what I can do to check what could have gone wrong?
Thanks in advance.
