I'm getting a pc for my daughter. I'll install Fedora KDE Spin. I'm looking for a parental control solution that also integrates with her Android phone. I'm currently using Google's Family Link which while not great it offers enough. I'd be happy to move to any other solution that can count both device's usage screen time as one so she doesn't use up her phone and then move to the PC.
Personal opinion, I don't understand why more parents haven't moved to use Pi-Holes for content blocking. Since you can tailor your own blocklists, it's not impossible to do, and I'm pretty sure some enterprising folks have already made a Pi-Hole block list for porn and various adult websites.
Further, if your child figures out how to bypass the block, they're learning valuable skills, if nothing else.
To be fair, it seems like you're more concerned with overall screen time, and I don't have a better solution for that than you already have.
Run pihole with a MikroTik router at your houses demarc.
Set up firewall rules in the tik to redirect any packet with dst tcp/udp 53 outbound on wan to the pihole. If you’re worried about dns when pihole is down, create disabled rules to allow the dns traffic as well, then set up a scheduler script using if blocks to toggle the sets of rules depending on status.
This will force any client on your network, even one with hardcoded dns IPs, to use the pihole.
If the client is configured for DoH you’ll just have to build out an ip block list in the MikroTik and block all known DoH IPs.
Create firewall rules to drop all vpn traffic you can, combining port based rules and similar IP lists as for DoH, but subbing in VPN provider IPs. If you want to route your home traffic over a vpn, set up a vpn client in the router itself and basically site-to-site your home to the vpn provider you use.
This would block the vast majority of kids trying to bypass parents blocks, but it’s asking quite a lot from the parents who don’t have experience configuring this stuff already.
I knew the forced dns thing because I have a pihole, and blocking port 53 traffic not heading to my two PIs has not happened yet, despite my best efforts. Shit aint simple for me, much less regular people.
I can’t quite get a read on if you’re being sarcastic or not, but if you are you should know that there are curated porn blocklists for pihole. This obviously won’t stop anyone from accessing porn via nsfw channels on sites that are not exclusively nsfw, like lemmy, Reddit, tumblr, or whatever.
