ufw firewall disabled - How to turn it back on?

  • 772

I am using Ubuntu 12.04 and just recently noticed, that my ufw-firewall is turned [off]. I know It's turned [off] by default, but when I set Ubuntu up, I turned [on] the firewall with:

sudo ufw, but today I just noticed that ufw was off, so I tried sudo ufw again in a terminal window:

morgan@morgan-HP-Pavilion-g7-Notebook-PC:~$ sudo ufw
[sudo] password for morgan: 
ERROR: not enough args

I don't know what else to do, to turn ufw back on!! Please help and thanks. -Morgan Beck
