A Parent's Guide To Linux Web Filtering
Roblimo writes "Not all parents want their children exposed to everything on the Internet, especially porn. So far, virtually all home-level Net filtering software has been for Windows. This tutorial on NewsForge, by Joe Bolin, shows Linux-using parents how to set up Web filtering for *their* children -- and shows them how to customize filters to fit their own tastes and beliefs instead of relying on a commercial software company's ideas of 'good' and 'bad,' too."
The easier and more accurate it is for parents to filter content for their own children, based on their own values, the less likely it is for them to scream for the government to do it for them.
A nice how-to. This could be fun in the hands of kids to filter their parents Internet to only include toys and cartoons and... uhm... slashdot...

This could really help push Linux for schools and libraries. (who don't need the extra expense of the "secure" kiosk's their paying for now.)

Make sure you add /. to that filter if you ever want your kids to grow up to be productive human beings. Otherwise they'll be just like the rest of us, lurking around until the next item is posted. I've got some work to go not do now ...
Steal This Sig
Those fun-loving shareware dudes and dames over at Freeverse have a customizable browser for kids, aptly named BumperCar. Don't know much about it, but I happened to see it on a browsing jag yesterday, and thought I'd mention it here.
The CB App. What's your 20?
I thought we were mostly in agreement here. Consorware is bad. Filters don't work.
Why is it that censorware suddenly becomes good when it's implemented by an open source program?
Granted all the software is released under GPL and source code included, all it would take is for the kid to either A) Learn a little C++ (or whatever language this software is coded in) to make the software worthless or B) Start hunting for a patch that someone else was nice enough to build. Though if your kid can learn C++ I presume he's probably mature enough to view anything he wants and parents should stay back. However full censorship in Linux,IMHO because of the nature of open source is just next to impossible. As it should be though :-)
...in bed
I say just run the box in console mode, and if the kid can figure out how to configure X and open a browser, they are old enough for porn.
Seriously, this is a little strange in it's scope. In the fourth paragraph, it defines for the reader what a "server" is, and then they expect the reader to be comfortable just jumping right in and editing the squid config. Seems like a little user-friendliness is probably needed before we can consider the parental filtering thing taken care of...
Paper Pusher
I have been developing an algorithm that scans images and can detect whether there is a nipple in the image. If this were incorporated into an http filter, you could get rid of porn and possibly notify parents when nipple-laden images were being downloaded.
The only technical problem at present is that I can not discern between human nipples and animal nipples, so some images of cow udders and the like register false positives. Nevertheless, I think this is a very important algorithm.
I have considered selling this to the Justice Department, as Atty General Ashcroft has expressed an interest in this kind of software. However, I feel this is too important to be closed. I am happy to say the project will be listed at Sourceforge soon, and released under the GPL!!!
Man, if you think the only things that you can find on the Internet are naked people and goatse, you must have been on the Internet for all of about 8 seconds.
Parents need to protect their kids from extreme pornography, highly graphic images (like rotten.com and the like), and websites that foster extreme viewpoints and hate speech, like the Aryan Nations. These things can have a much more profound impact on a child's immature mind than it would on a mature and rational adult's mind.
What your personal threshold for your family is as to how extreme content has to be before you feel the need to protect your kids from it is dependent entirely on your own belief system. This is why systems that allow the parents to decide criteria, rather than depending on things like Net Nanny, is so attractive.
So much is made about filtering content for children, presumably to prevent them from wandering upon unsuitable content. The fundamental flaw with this (techological limitations notwithstanding) is the notion that kids under the age of 13 or so should be left alone to browse the net.
It seems to me that proper parenting requires an active participation with your kids, whether it be in watching TV, checking out books in a B&N, or spending time on the net. Simply throwing in a vchip, blocking channels or applying hole-ridden filters can never be a substitute for actively being entertained, lerning, etc. alongside your child.
At least I think I read that somewhere...

Putting filtering on Linux doesn't make it better. Filtering still:
a) doesn't work. Kids who want pr0n will find it, or find a way to get around the filters; and
b) creates and adversarial relationship between parent and child instead of a collaborative one.
Having parents set up their own filters instead of trusting an outside organization to do it for them almost GUARANTEES that the filters will not be effective. Who has time to be comprehensive on content, given the rate at which new sites are created? The only alternative is to trust some organization that does have the resources to do a more comprehensive job, and even then will not be complete.
The more serious issue is the loss of trust demonstrated by putting filtering software on the computer.
No matter what people say, how futile it is etc etc, it's an important step in getting Linux to be more common in the educational environment. A school or library needs to be able to say "we tried our best!" when it comes to these things. It helps linux get its foot in the door.
Really, is only naked women or men. In Mozilla Firebird, I have setted it to "Block images from goat.cx" (not visit!) and if my kids pictures of naked people find, fine. I did as child. I run linux but don't need this.
Well, there's naked people, and then there's porn. Personally I'm more worried about sites like bangbus which come 1/2 inch from condoning rape. I don't want my son treating women like that, and I don't want my daughter being treated like that, clothes on or off.
As friend said "You Americans are so puritanical!"
And that is just insulting. How do you resolve the above stereotype with the fact that most the porn *origninates* in the States? I suppose you think each and every German wears liederhosen too?
What "average" users do you know that would be comfortable with modifying .conf files and all that other crap that this forces them to do?
Anyone who calls this process "easy" is completely out of touch with the average PC user.
"Ask not what your country can do for you." --John F. Kennedy
Then go looking for news articles about kids being lured to their death by people in chat rooms, etc. You'll find plenty.
You need to monitor what your kids are doing on the net. The children aren't responsible for their actions, You are.
Yes, my daughters love pill bottles. Love to try and open them and eat anything that pops out.
But according to half the people here I should let them at it.
While this might take care of keeping kids off a large number of porn sites, it still will allow kids through to sites with all pictures. Those can't be filtered by keyword.
My personal belief is that kids under a certain age should NEVER be on the Internet without close supervision. As the kids get older, they should be given more freedom to explore by themselves, but monitoring software is still a good idea.
A close friend of mine who's 18 and getting ready to go off to college still isn't allowed on the computer when her mom is at work during the day. The computer is password protected so the mom has to be around when they're on it. They just accept it and deal with it. She doesn't sit and watch over their shoulder now that they're older, but she's at least around and able to glance at the screen occasionally.
You have enemies? Good. That means you've stood up for something, sometime in your life. --Winston Churchill
Frankly, you're not going to beat sitting down with your kids and talking to them about where to go on the net and where not to. I mean this software helps but isn't that hard to get around. All the kid really has to do is boot the system with knoppix or root the box. Some people might laugh at that notion but think of what you would do at this age. Most linux people have that sort of "I want to do this just because I can" mentality. If that gene has passed on, you'll need a little more than iptables. :)
When I was 10, my dad had a net-nanny type program on the machine allegedly to protect my younger brother. It timed internet access and cut you off after a certain period. So I opened up regedit and ripped the program out manually. Sure, the system was barely functional, the network connection didn't work at all and the machine needed to be reinstalled - but that nanny software never came back.
That's two too many, as far as the target audience is concerned.
Netfilter is part of the linux kernel and doesn't require a separate installation. As for the other two, the entire unix philosophy is build small tools that do one thing well and connect them together. If someone doesn't like Squid, they can use another proxy server without ditching Dan's Guardian (or the other way around). It's called choice. It's a good thing.
Not that it matters; they'd probably already lost most of their target audience.
Their target audience is mostly parents who are already running Linux. The "hoops" (that you admit to not reading yet feel the need to criticize anyway) they have to go through are little different than configuring any other Linux app.
People's desire to believe they are right is much stronger than their desire to be right.
Putting limits on material they want their children exposed to is a HUGE part of parenting. So why do you oppose software intended to let parents do just that?
"Ask not what your country can do for you." --John F. Kennedy
Regarding all the "kids will hack it" and "watch your kids" content so far.
The underlying issue is quite simple - Access to the Internet is the equivalent of allowing your kids to leave the yard without permission, not bothering to know where they are, who they're contacting or being contacted by and generally leaving them at the mercy of the big, bad world.
So, establishing them on isolated segement NAT'd computers where every single 0 and 1 goes through a router that their parents manage or through a proxy service of the same circumstance isn't anything more complicated than insuring that Jack or Jane ask permission to leave the yard and to know where they're going and who they'll see when they do.
With kids, you don't throw out the rules for sake of convenience or with the idea of being "progressive" about child rearing. The consequences are just too dire.
Mod me troll, if you must, I can't help it.
Does this mean parents will actually have to talk to their children? Does that mean they will actually have to teach them values and standards of their own?
You don't say. What a shocker!
I have been on the internet for 10 years. Back then I was 17, which means I was not really a child. However one thing I learned quite quickly is that you have to search for porn/hatespeech/$fill_in_gross_stuff. Yes, I know rotten.com and I have visited it. Stuff there was quite a curiosity the first time I saw it.
Now, 10 years ago there was a child in this house. My sister. She was 12 back then. I did not once see anything questionable on her screen, nor in her browser cache (I used to monitor her stuff as a worried brother, my parents couldn't have done it) This means: if your kids go and visit those sites they have searched for it, or got the link from a friend. In the latter case you can be pretty sure they that they would have gotten the information anyways. I mean: how hard is it to go over to your friends place and ask him/her to show the site that you couldn't visit at home.
So, if I'm ever a parent, I'll just make sure to monitor what my kids do and not block their access. If I catch them doing something I can't condone then it'll just be time for a little chat.
Ahhh...the great dumpster continuum. Many a free computer will be found there. -- sowth (748135)
I honestly don't see what the problem is. Although my world view has changed somewhat over the years, I don't *think* I react that differently to things now as to how I reacted when I was, say, 12 years old.
Has anyone applied a Bayesian filter to web content? This would be an interesting way to give the filter a set of initial conditions from which it could derive an ever-increasing better filtration of content based off the parent's initial criteria.
If there is a pre-existing application, I would interested to know.
You are looking at this as though parents making mods or installing software are trying to prevent kids from looking at something they are actively searching for.
The real reason we want this stuff is so the kids won't stumble on to something bad they had no intention of finding. The lack of trust being demonstrated is a lack of trust toward every jerk on the internet that doesn't care about my kid.
That's my reason anyway. Does anyone here have kids?
This whole article is a complete waste since we all know that people who use Linux cannot attract the opposite sex which therefore means that they won't ever be able to have children. Its in the GPL too, somewhere around the 30th line...
"If you can comprehend the aforementioned statements and use this software, you will not get laid. Ever. I know this because I'm RMS and chicks dig bearded guys. I haven't been laid yet so you won't either."
Still, we all know that chicks dig BSD instead.
What I've done in the past is setup linux boxes for people with all outgoing access closed - with a script, the user entered the address they want to connect to (disney.com). The script then logs this, and allows outgoing access to the sight. This way, there isn't a lot of pre-setup stuff to do. With everyone understanding the usage is logged, it keeps them honest. Mom and dad can checkout the log with a web browser. Submitting content took some work to get figured out.... Not a perfect system, just a little different.

You miss the point entirely. This article is good because it puts the power of filtering in the hands of the parent, where it belongs *NOT* the government.
we have a few on our street who demand "GO SLOW! We love our children!" signs from the town instead of teaching their kids not to run into the road
You're obviously not a parent. If you were, you'd never make such a moronic statement. Kids do stupid things. You can teach your child not to run in the road - is that a guarantee that 100% of the time the lesson is going to stick?? Hell no!!!! That's why residential neighborhoods usually cap the speed limit at 25.
I don't see how filtering for linux is going to help. You're not very likely to find linux running in in a trailer park, folks.
Insightful, my ass. This article isn't for Joe Sixpack. It's for Linux users who want a filtering solution. If I'm a Linux user, and I want to apply net filtering for my kids, this is how I do it. Pretty simple logic, huh bubba??
Xenon, where's my money? -Borno
My wife (OMG, ./er who is married) calls these parents "Helicopter Parents" because they just hover over their kids, but as soon as there is an incident with regards to the child and the school and/or teacher, they immediately fly on in assuming that they (the school/teacher) are the cause of the "accident".
It's sad when my wife is surprised that the parent(s) supports the teacher's or school's position. She actually got offered $5k by a parent to pass her child so that they could get the kid out of the house (this was in the affluent Plano west high school). She turned it down which is probably why she's a teacher and I'm not...I'd take the $5k and still fail the dumba$$
"Look Lois, the two symbols of the Republican Party: an elephant, and a fat white guy who is threatened by change."
My proxy system enforces just a few basic rules:
I told her straight out, if you think a blocked site is legit, just tell me and I'll see about unblocking it. I have blocked a few fringe science, religion, and political web sites. When she refused to discuss the contents with me, I blocked the sites. I was perfectly willing to leave them unblocked, but only if she was willing to discuss them rationally with my wife or myself.

I have used dansguardian on ipcop for several different sites (schools, homes etc), and have been please by the relative ease of installing (as far as linux stuff goes) and the configuration options.
I have used IPCOP v 1.2 and 1.3 w/o any problems. Sidenote :it runs well on an older pentium 133 box.
Well, I am a parent and the reasons are not always what you'd think. First, note that my 3 year-old doesn't do any more with our computers than type his name and those of his friends (hey, it makes him happy
That said, children vary in their responses to different things. I tried watching Miyazaki's Spirited Away with him. Yeah, I read the "scary for kids" warning, but I figured I'd gauge his response to it. He was terrified. By what you ask? The scene where the child's parents turn into pigs. He's not afraid of pigs, he thinks they're funny. But he was terrified that his mother and I might turn into pigs like in the movie. Make sense? No, but he's three years old!
In real life, we already have issues with him being influenced by kids whose parents (if you can call them that) apparently have wildly different ideas about childrearing than we. So he already knows a few words he we don't want him using and has made a few statements that would be pretty nerve-wracking if he actually knew what they meant. We can handle stuff like this because it's out front. If he were learning this stuff online it would be much more difficult to figure out the source and decide how to handle it.
Most parents' response to the net is similar to how they view books or movies: I don't want my son watching "Saving Private Ryan" for quite a while because I know how many nightmares he'll have. But if he happens to see the occasional bare tit on TV, no big deal. He'll just giggle and forget about it.
The fundamental issue is that of not exposing a child to material that he's not yet ready for. And this decision should rest solely with the parent. Our job's hard enough as it is; for those who want to use it, filtering is just one more tool.
Most of the posters seem to be parents here, so I'll give another perspective - the childs. I'm nearly 17, and I've had fairly unrestricted access to the internet for, hmm, probably about 5 years and used it a little before then. I've read and seen things on the internet that could be grouped into pretty much every category conceivable, and guess what? It hasn't done me any harm at all. In fact, I'd agree with the people who say it prepares you for the real world that little bit more. I don't have urges to rip my ass cheeks apart, drive around in a bangbus, or hate black people. My parents set a few (fairly unrestrictive) rules about my internet usage, and as long as I behave in a reasonably acceptable way in general, they won't have any reason to look at internet usage or anything else.
