you've arrived that interesting problem of how to administor
(or configure and control) mutiple systems from one place (aka, the administrator's system).
big companies do this with the Domain Controller (DC) software which is expensive and a whole new set of programs to learn - -
not very practical for the home user.
without a DC, there are really just two kinds of choices:
a) use something in the network above all these systems to control what they all get to see or access
b) install some program EVEYWHERE, configure it on one system, and then find some means to copy the configuration settings to all of them.
when we typically have home networks like
Code:
modem==router---> lan attached PCs
One central location that shouts at us as a candidate for centralize control is - - - the ROUTER.
If you can pick a good one and get sufficent control there, then your task is not too difficult.
My NetGet router allows
Key Word Filtering and will block any URL which contains any
word or work fragment in the list of keywords. Sadly, this is limited to a small set of key words and
will never catch everything (ie: too many ways to create URLs which do not imply the content on the page).
