[Gloucs] parental control

[Paul Robertson]

I am coming under pressure to implement some kind of parental control over 
www access at home.
We use both Windows and Linux and as our kids are quite young, the main 
risks are of accidentally turning up unsuitable material on the web.
It would be nice to block popup ads too.
I assume this can all be done using a linux box as a firewall / proxy 
webserver.
Has anyone done this who can point me in the right direction?

Thanks,
