porno filter...

Are there any free porno filtering software for Windows that anyone can recommend?

I'm trying to setup a public hotel terminal and the owner wants the porn sites blocked. I've begged and pleaded with him to let me install Linux with Dansguardian, but he just kept whining about Windows. So I ignored him and installed Xubuntu anyways (it's an older low-spec Dell machine P4 2.4 Ghz with only 256MB mem). He grudgingly admits to liking it, but it's gotta be able to go back to Windows on-demand. I'm tired of arguing, so it's back to Windows.

The only thing I've seen so far is K9 Web Protection. I can't tell if they charge or not. They appear to be giving it away for free.

Open source is fine, but I'm talking free as in beer. I just want something that works. I'm not looking for a lot of control over the program, but it needs to block porn sites (without me needing to enumerate them), and if necessary it needs an option to whitelist sites that shouldn't have been blocked in the first place.

edit your hosts files perhaps?

but then he'd have to spend countless hours finding every single porn site

Time well spent. I'm on it.

let alone that there are places (http://hostsfile.org/hosts.html) that contain said files ready for porn filtering.

Is this just a walk-up free terminal that people can use to check something real quick? Or a more specific purpose? Honestly, you're never going to be able to blacklist ALL possible porn sites. And that's not even considering what or who defines the porn. I guess your boss, in this case.

Anyway, if this terminal is in a public-enough place, I suppose a good blacklist and the shame of looking at it in public would prevent most people from browsing porn.

However, if the terminal is in a semi-private place, and/or has a more specialized use, you could block all traffic except on a whitelist. That would do the trick.

run this dansgaurdian as the gateway for the network.

Just run OPENDNS. You get a faster DNS server and can set optional filtering options.

I tried this once. The terminal seems to be behind a proxy somewhere that is caching DNS requests. OpenDNS was never able to block anything.

The owner doesn't want the entire network blocked. If you bring a laptop to your room and use the wifi, browse porn all you want, just not at the public terminal in the lobby.

Public free walk-up terminal in the hotel lobby for guests to check email, browse the web, and open office documents. That's all it needs to do.

I don't need it to block every porn site with 100% accuracy, it just needs to block the majority (let's say > 95%). As for what constitutes porn, I'll use the definition of anything you wouldn't want your mother or your kids to see you looking at.

A decent blacklist (and an implementation method) is all I'm looking for. General web browsing rules out using a whitelist.

The link says service unavailable, but that's an idea. The problem is that I'm just setting this up, a one-time thing. The owner is NOT tech savvy. He would not be able to update the list.

Surely there is something like Dansguardian for Windows. Dansguardian (for those who don't know) is a content filter. It requires a proxy to fetch pages for it. On Linux, you can setup iptables to route all web traffic to the proxy which then uses Dansguardian to filter. You can black/white/graylist specific urls or sites, but in addition, it also uses a weighted phrase list. So it's not just blocking playboy, it's blocking google searches for playboy (and generic terms).

Hmmm... Now that I think about it, I wonder if I could compile Dansguardian under cygwin...

or, as you said, have the terminal in question use dansgaurdian as a proxy...
