Has anyone looked at or successfully integrated DNS filtering into NethServer?
I’ve been using NxFilter: https://nxfilter.org/p3/ in a school environment, yet it is running on a separate server. It’s working well and, for me at least, a better solution than the previous transparent proxy setups.
Are there perhaps any other linux based products that I’m not aware of? Or some tricks to implement filtering (in a simple way) in BIND etc?
Alternatively, according to theiur docs you can nxfilter on a linux syste, nxfilter is a java application, so you could give it a try on centos. There are already several java applications for nethserver: Webtop5 and SavaPage.
Maybe you want to give it a try to install nxfilter on nethserver? If you run into issues, you can always ask for help.
Nxfilter looks like a very nice project. Especially for school environments. Another option could be using shallalist, but I believe those can be implemented in squidguard.
Maybe we should start an effort to get nxfilter available on NethServer by starting with a feature request.
