[Discuss] Port Scanning

[Kent Borg]

I seem to remember someone saying that firewalls don't fail "off", or 
something like that.

Well, on a Linode machine I have, running very standard Debian, with no 
real customizations, I noticed today the firewall was off:

> root at www:/home/kentborg# ufw status
> Status: inactive
> root at www:/home/kentborg# ufw enable
> Firewall is active and enabled on system startup

Good thing the firewall is only an extra layer of security and *not* 
fundamental.


(Linode/Akamai recently did a reboot of my VM because of some problem on 
their end. I suspect that is when it quit walling. I'll have to do my 
own reboot as a test.)
