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@www:/home/kentborg# ufw status
Status: inactive
root@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.)
