I have installed zeroshell for a school and it’s running like a charm! Thanks to Fulvio. However, I have a problem blocking adult materials, I have tried openDNS but it looks like my ISP doesn’t allow me to bypass his DNS servers and use those of openDNS.
I have contacted openDNS, they are trying to help but without success.
So I would like to know if there is another solution to block adult materials, as this is crucial in a school environment.
I saw DansGuardian updates but the last updates were in 2013 and I am running Zeroshell 3.5.0, would this work ?
