I have an Ubuntu 16.04 AWS instance that I accidentally locked myself out of by enabling UFW without allowing port 22 for SSH. I've created a new instance and mounted the volume of the affected instance to it.
Now I have access to the file system of the affected instance, how do I stop UFW from running on startup so that I can access the instance again through SSH? Alternatively, how do I allow access to port 22 for SSH through config files?
I've looked around online and my file structure doesn't seem to match what other people are using. In
/media/myDrive/lib/ufw I don't have
user6.rules; these are in
/etc/ufw/. I've edited the
user*.rules files as below to allow access, but when I rebooted the server, I still couldn't access it via SSH.
#user.rules -A ufw-user-input -p tcp --dport 22 -j ACCEPT -A ufw-user-input -p udp --dport 22 -j ACCEPT #user6.rules -A ufw6-user-input -p tcp --dport 22 -j ACCEPT -A ufw6-user-input -p udp --dport 22 -j ACCEPT
