I can't seem to find a quick command to just view all the banned IP's on the server. Or is there a file I can just edit?

I'm guessing fail2ban is the one that inputs all the IP's to ban. Where do I adjust the settings for it?

I seem to be able to only login to my server remotely only if i disable ufw. I can't seem to find out how to unban myself. I don't even know why i was banned in the first place. Is there a log of some sort to view all the attempts made?

sudo iptables -L INPUT -v -n | less

This tells iptables to List all rules in the INPUT chain, providing verbose numeric output. We are piping through less so that we get it a page at a time.
