Example with duo 2fa for webmin

Hi all I'd like to ask if duo 2fa would be an interesting for the GUI to implement natively. In the meantime this is my shortcut on how to do it on Ubuntu16.

(Of course you need a duo.com account, a registered app, and every user used must be enrolled, and confirmed). This shouldn't lock ssh out of the system AFAIK.

Best, Manu

echo "deb http://pkg.duosecurity.com/Ubuntu xenial main" > /etc/apt/sources.list.d/duosecurity.list

curl -s https://duo.com/APT-GPG-KEY-DUO | sudo apt-key add -
apt-get update && apt-get install duo-unix

apt install libauthen-pam-perl

mv /etc/pam.d/webmin /etc/pam.d/webminBAK
cat > /etc/pam.d/webmin << EOF
