Kid filter?

[ToddAndMargo]

Hi All,

Is there any such thing a kid filter to
keep incorrigibles off porn and dating sites
for Fedora?

Many thanks,
-T

The only thing I can think of offhand is using /etc/hosts to assign them 
an address of 127.0.0.0, making them unreachable.  There was a time when 
I used that to block goatse.cx, along with a few of the other more 
obnoxious shock sites, but I haven't needed to bother for a long time. 
One nice thing about doing this on Linux is that you don't need to 
reboot after making changes as you do with Winderz, or at least did when 
I worked with it.

Does anyone publish a list of these site to block?

A quick bit of googlemancy on /etc/hosts block brings up a long list of 
sites discussing this.  It's late at night and I have other things to do 
before going to bed so I'll let you check them out for yourself.  HTH, HAND.

I've used this tool to generate hosts files for a large number of semi-
unamaged PCs at my work.  They are in remote offices and have no real
infrastructure to set up proxy servers.

We use a spare server as a firewall, put untangle on it, works great

An arranged marriage?

But, being serious, does your ISP offer any filtering options?  My
modem/router supposedly offers such a feature, too.  Though if you want
to do it yourself, you can do proxy filtering using Squid.

If they have smart phones, that's going to bypass anything you try
outside of their phone.

If they're using their phones at home and using your WiFi, filters on 
the router will work.  Once they leave home with their phones, what I 
quoted above is absolutely right.

And as noted, any home-based filters will fail if they can connect their
phones to some other wi-fi than yours. School networks are probably
filtered, but of course coffee shops and other public hot spots likely are
not.

At work, we used to use OpenDNS to keep porn off our network. Since we
received US Govt. funds, we were required by an Act of Congress to take
steps to keep porn off our network. Obviously no one can check to ensure
there is no porn on every network that receives funds, there were a few
"approved" methods to comply, and OpenDNS was one of them. I think it's
pretty effective in general, as they do a good job of keeping their list of
porn sites up to date. They also block phishing sites (web sites that mimic
real-world sites in an attempt to convince you to give up the private info
they are trying to get), which is (to me at least) far more valuable than
blocking porn.

We of course had an enterprise account, but you can use the service for
free as long as the number of queries you generate is small enough
(probably most home sites would qualify). You can go to opendns.com for
more info.

+1 to ^^ they are great. I used it with all my kids (really trying to 
avoid accidental exposure).  You can also, on android phones, set a DNS 
server that is queried instead of the ISP / cell provider DNS. I have 
not experimented with this for content blocking but I have used it with 
wanting to use say google's DNS rather than letting whatever wifi i am 
track me. It can cause some problems with things like captive portals 
but generally works pretty well.

Just point the DNS server to Open DNS?

DNS1: 208.67.222.222
       DNS2: 208.67.220.220

[Greg Woods]

That is what I have tested at home and it seems to work. If you want to see
it in action you can go to internetbadguys.com (a site run by OpenDNS) both
before and after setting your forwarding DNS servers to those of OpenDNS
and note the difference.

Not Fedora, but have you consider pie hole? Can put it in a
docker container or vm guest, or in a RaspberryPI as the name hints
at.
