Accidentally ufw aws disable

Detach and fix the volume of the problem instance using another instance

• Launch a new instance (recovery instance).
• Stop the original instance (DO NOT TERMINATE)
• Detach the volume (problem volume) from the original instance
• Attached it to the recovery instance as /dev/sdf.
• Login to the recovery instance via ssh/putty
• Run sudo lsblk to display attached volumes and confirm the name of the problem volume. It usually begins with /dev/xvdf. Mine is /dev/xvdf1
• Mount problem volume.

$ sudo mount /dev/xvdf1 /mnt
$ cd /mnt/etc/ufw

Open ufw configuration file

  $ sudo vim ufw.conf

• Press i to edit the file.
• Change ENABLED=yes to ENABLED=no
• Type Ctrl-C and type :wq to save the file.
• Display content of ufw conf file using the command below and ensure that ENABLED=yes has been changed to ENABLED=no

  $ sudo cat ufw.conf 

Unmount volume

 $ cd ~
 $ sudo umount /mnt

• Detach problem volume from recovery instance and re-attach it to the original instance as /dev/sda1.
• Start the original instance and you should be able to log back in.
