Subject Re: [users@httpd] Best practice for restricting access to exact IP addresses
Date Fri, 01 Dec 2017 15:36:23 GMT
That is almost identical to what I discovered independently.  I read every
active .conf file in entirety to realize this.

I was on the assumption that from a web client perspective, a2dissite on
all sites had the same effect as stopping apache, essentially forcing it
idle.  It appears that a2dissite doesn't really truly take all sites
offline, but instead defaults to a precompiled string for the document
root.

That seems to invite a hazardous situation, say for example a user is
virtual hosting n sites and uses a directory structure inside /var/www/
such as:

/var/www/www.example.com
/var/www/www.example1.com
/var/www/www.example2.com

and then believes that running a2dissite on all these, perhaps to make a
backup of a php-encrusted website (such as mine) that the document root
will default to the top level of all these sites and perhaps reveal SQL
passwords in the process.

I hope this is not true...
