[SLUG] Need to implement a Net Nanny on Ubuntu PDQ

2009-11-04 Thread Kyle

Hi Sluggers,

well, tonight was certainly an eye opener. So, ok, I apparently need to 
implement some form of Net Nanny software and pretty damn quick too.


Can anyone recommend some form of package-based (Ubuntu for the local 
machine or CentOS-RHEL for the gateway) Nanny software pls? I really 
need something I can just install, do some form of basic (I mean BASIC) 
config and it will keep itself uptodate with regular machine updates. I 
really haven't got the time to learn some heavily convoluted new package.


What are my chances?

As I say when the same issue comes up in a business context, this is a social
problem and technical solutions will only get you this far: .

Do you want to pay money for it?  http://dansguardian.org/

The software is free, but I don't know of any well maintained blacklist that
provides filtering of the sort you are likely to want.  The commercial
options, found on the site, do however.[1]


Personally, though, I would solve this in a different fashion: social control,
aided by small technical assistance.  Specifically:

Assuming the problem user doesn't have root, and doesn't have a sensible way
to get it, configure squid, and use a firewall to block any outbound traffic
except via that proxy.[2]

Then read the logs.  Make it known that this has happened, and that you /will/
be reading the logs.  Do it.  Look for proxy sites and HTTPS access, too, not
just the immediate sites, because eventually they will be tested.

Just read them every now and then, or grep them.  After the first month or two
you don't need to be thorough.  Personally, I would have something schedule a
*random* check between three and fourteen days from now, and repeat that every
time.  Genuinely random, so you can't be gamed.

That should sort out the local stuff, at the cost of whining about games and
IM that are no longer easy or pleasant to use.


Um, and assume that this is going to get worked around anyway, because there
is always a way around it.  For example, a friends house, a USB stick, or a
suitable Internet cafe, or the school network, or...

Both valid points Daniel,

but tell a 9yr old not to search for whatever naughty stuff it is that 
happens to be floating around school. Take into account that not 
everything that should be behind youtube's 18+ section IS actually 
behind the 18+ section and you get the picture.


For now, I'll settle for blocking things in-house. I can't control what 
happens outside. At least not fully.

Please, don't get me wrong: I am not suggesting that your desire to police
this is wrong, or anything like that.  I hope you succeed, even if you don't
think it is likely.

 Take into account that not everything that should be behind youtube's 18+
 section IS actually behind the 18+ section and you get the picture.

*nod*  Actually, one of the biggest problems[1] is that there are a huge
number of briefly existing collect the free bits sites out there, usually on
some random blog or other...

 For now, I'll settle for blocking things in-house. I can't control what
 happens outside. At least not fully.

*nod*  Anyway, the dansguardian stuff is pretty decent, and hopefully will do
what you want.

Um, and I forgot to suggest: you might also call your ISP and ask them if they
can offer anything by way of a solution.  For all the moral panic about
needing to implement this stuff a *large* number of ISPs previously offered a
filtered connection service at a fairly reasonable price.

That actually *improves* your solution, because (A) you don't need to support
it, and (B) you are going to have to pay that anyway.
