Blocking sites by keyword

    I would think the easiest way to block sites of ones choice (porn, for example) is through their router. Many routers have an area where one can use keywords and domain names to block whatever is needed. If one doesn't know how to get into their router, look for the manufacturer and model number of the router and enter it into a Google search and include "router access." Many manufacturer's sites offer easy to follow instructions. 

    I'm new to OpenDNS and thought to try it for the reason of the incessant everyday hacking of my own ISP's DNS of which they stated is secure. So far, so good with OpenDNS. I made it through a full day of hack-free enjoyment. I would think one of the reasons Open DNS was created was to help avoid the hacking issues at hand and offer protection. There is quite a bit of DNS poisoning/phishing and many are unaware of this fact, leaving many unaware of what to do about it.  It is far more dangerous having your DNS hacked and having your computer rerouted to other unsecured sites where phishing is prevalent, and this includes porn sites as well. So OpenDNS is doing what they were meant to be doing as well as the other protection they offer.

    There are other companies who offer website and keyword blocking, and/or the use of your own router settings as I mentioned.

    OpenDNS is a great service.  However, I too think it would be nice to have domains blocked that contained keywords.  Perhaps, it's not a DNS service in terms of a technical implementation.  It could be another service.  As stated there are alternatives, so I would not stop using OpenDNS for this reason alone.  They are running a business and need to do what is right for their strategy.  So, I'm sure if enough demand existed, they would find a way to offer such a service.  I know I would even pay extra to have it in one package for the convenience.

    We must also consider that this potential feature isn't bullet proof either, so many other measures should still be utilized.

    One additional tip I have for autism parents is to use OpenDNS to review traffic periodically to discover new sites to add to the blacklist.  If they are repeaters, you should see the same site being accessed a lot.  I've found a few that way and added them to my blacklist.

    It is tough to balance the benefits of the internet while keeping some of its openness away from our kids.

    potentially useful if not overly aggressive... sooo many domains, too many to challenge as they go up and down instantly...

    I agree that being able to block keywords at the domain name level via OpenDNS would be a nice feature, and provide additional flexibility.   No regex -- just plain text matching with generic wildcard (* and ?).

    Having someone who has a seriously bad addiction to porn in our family is why we use OpenDNS sadly it fails when you use sites like tumblr because without keyword filtering you can goto twitter, tumblr etc and look at the same porn without triggering a URL filter rule from the root domain.

     

    Our issue at home is very serious and is something we're working through to resolve its not something to joke about with either, You may want someone to see tumblr.com but not xxx.tumblr.com so a filter system would be great I would even pay the $$ for it if the thad it

    Well, first to say, I am really happy to see at least some comments coming in backing my request.

    Some comments though make me wonder if I proposed to change the entire opendns service or so.

    Am using this service for some years now and everywehere where I am asked to install internet, I set OpenDns because it's great. No bashing at all as is said in this discussion somewhere.

    Just the plain simple question if OpenDns could add another quite simple service as I indicated above.

    A domain request is received, a small check is done if the user of the home network wants stringchecking. If so, a (limited?) list of strings is matched to the requested domain and if a string is found, an error can be returned except when the concerning domain is on the whitelist.

     

    All fully optional, so user who do not want this just don't turn it on. Just like stats or contentfilter or whatever.

    Of course you have to block tumblr but why when I only want to block tumblrs porn content - now thats where domain specific keywords could be very useful ... Im looking at other cloud solutions that are not too pricey as well as running my own proxy VPS to serve this feature perhaps.

    Many routers support keyword based blocking. Check your router for something like "Parental Controls".

    Very interesting thread. I will make an assumption that most paying customers, like myself, want the ability to filter out content on the dashboard and have it 'just work' (as an example, pornographic images). I imagine some purchase it so they can get to Facebook.com 'faster' using OpenDNS, I think others, like me, felt that by paying for the service and updating DNS on their firewall/gateway/modem device, they would magically not see porn (you know, by blocking the following categories: adult themes, dating, lingerie/Bikini, Nudity, pornography, proxy/anonymizer, sexuality, or video sharing. I've got a lot more blocked as well, including all search engines (yup, google, too), and am trying to use just bing for searches, but even that returns porn (search for 'sex' or 'vagina'). The keyword filtering, which is not available using OpenDNS, is what I am seeking, and open to your recommendations for this service. While I am happy with my OpenDNS service, it isn't doing what I expected it to do. perhaps I should have educated myself by reading these forums before purchasing.  Anyone know a kid-friendly search engine?

    @Davidlev:

    I use OpenDNS primarily for the malware protection, secondarily for content filtering, and lastly for speed.  I can't speak for everyone, but I imagine the majority of users are some mixture of those 3 categories.

     Understand: no search engine, no matter how much filtering is applied, is immune from someone purposely gaming the algorithm in order to deliver inappropriate responses to your queries.   Google SafeSearch is a good alternative, and while it is possible that some inappropriate content can get through, it is very reliable overall.

    I applaud your effort to block ALL material you deem inappropriate material; perhaps OpenDNS will provide keyword searching, but if you understand how DNS works, you will see how daunting a task it is.  Unless and until that happens, it may be that replacing your router will give you the more granular control (keyword blocking) you seek.

    Some have gone to something called "Pandora's Hope" which is a router of some sort for the whole house and have disabled safari on the other devices. I've got an Actiontec Q1000 that I have put OpenDNS into. Not sure what the Pandora's hope device does compared to my setup, but guessing if I search for 'vagina' on google safe search I won't find anything - even news articles - for vagina.

    This seems to be a very lively discussion. @tuckson what would you think about a petition to Google asking them to revert to the images.google.com domain? Services like SumOfUs.org and Change.Org are great for getting quick "signatures" from a network of subscribers. Thoughts from anyone?

    Indeed a lively discussion. So lively it actually surprises me a whole lot.

    As for the "Many routers can block" comments... true.... And many don't or just in a limited way. On my own router, I have 10 slots to place rules. I have 4 kids for whom I have set time slots, so half of those slots are filled... Then I have3 slots for additional rules, which make me have 3 slots left for string filtering... But .... each slot can only conatin up to 4 strings. 

     

    So yes... been there, done that.... And when I look around (I come regulary with friends/ acquintances who ask for help on their systems) I often see less expensive routers. Mostly bought because they don't have the s;ightest idea why paying more for a router would be useful if the cheaper one does it's primairy job. ;-) .

     

    So yes, many routers do, but also many routers don't offer this functionality.

     

    @ getrede...

    I don't really understand your suggestion? but again, this is only google... The fun of DNS is that it's at the beginnen of every webrequest.

    De domain is not relevent in what I mean. Because when a string is matched, the reauest should not be processed but immediatly be returned as being blocked.

     

    Acxtually the idea is quite simple ;-)

     

     

    Cheers

    We can talk, and we can suggest, but this history is that the idea bank gets no attention from OpenDNS. No matter how simple, how rational, how pressing your input may be, OpenDNS has little inclination to respond on these boards, let alone change how the system works. No key words, no time of day control, no category voting changes, no nothing.

    This thread began its life 10 months ago, and OpenDNS has not said word one.

    The other idea ban threads have the same sad history.

    Unless you have a technical issue thread, don't expect OpenDNS to respond.

    Look at www.covenanteyes.com if you want a filter system that works and responds to your needs. It aint happening here.

    @tuckson You know, I have exactly the kind of blocking that should be enough for you, combined with open DNS it seems to work really well.
    I use a good old fashioned hosts file. My hosts file currently has over 350,000 domains blocked in it and I use hostsman to manage it and also to display a message when a blocked site is attempted to be accessed. Lots of kids today know absolutely nothing about hosts files and so it's a very effective way of blocking specific sites. Of course you can't start blocking them manually, but if you install hostsman then it has the setting to download the latest updated blocking list and there's a porn blocking one too.
    I also would advise looking at routers and seeing what parental control solutions some of them have.
    Don't underestimate the hosts file though!
    I wish you every success mate, good luck!

    Hi
    I think dns ip use to block website very good and reliable way to control adult content website . But between all this there are weakness in it , for example when you search about image & videos in google search drive web you can see adult content very clear so what we can do to block this one also . Thanks for opendns

    You either block the search engine (e.g. Google) itself, or your make use of the search engine's family filtering features like SafeSearch in case of Google.

    I too think it would be great to be able to block key words and I would love a Christian based browser that didn't show all the nasty ads that are on the regular ones as well as news sites. You can't even read the news online without being visually assaulted!

    OK.. I have extensive networking knowledge and a server at my disposal, have the ability to kick the kids off anytime I want.  But I have to get that special balance with what the kids can have access to and what they cant.  If you have full control over the PC (Windows based) there is nothing easier and more effective than K9 by Bluecoat Proxy (www1.k9webprotection.com) And its free... It creates a proxy on the computer and forces it as the gateway.. Works with all browsers old and new, and even the hacker browsers that claim to get by crap, also even VPN proof.  But what if your using a computer without admin access (such as the one the kids bring home from school), Iphone, Ipad, Android, Tablets, nooks, etc.

    Here is my setup, adult friendly, and kid friendly, and quite easy to setup.

    Adult Friendly -- For example I need YouTube for hardware tutorials for work, my wife needs Facebook for her small business.  We in the past had in incident on facebook that requires me to block it out from the kids (along with all social media).  Youtube is a timewaster for the kids they use it to entertain themselves when they should be working on school work or homework.  Also we wanted the network to lock for the kids at night (bedtime).  We needed much more controlled access in early afternoon when homework was being done, loosen up a little in the evening, then off at night.   HERE IS THE SOLUTION.

    Cable Internet into Primary Router w/ WIFI (Network called Witech77) using ip range 192.168.77.xxx

    Purchased a cheap Net-gear N150 that had keyword blocking and Open DNS proxy (The cheaper the router the more likely to block keywords - dont know why)   44$ at the walmart.

    Plugged my cheap Net-gear routers internet port into the primary router.

    Went into the settings of the Net-gear and set it to be (Witech Proxy 78).  using ip range 192.168.78.xxx

    Turned on the parental controls, set the DNS to point to Open DNS, setup the keyword blocking.

    Gave Adults access to 77 Network, Kids access to 78 Network.  Due to standard routing table rules, the kids will

    still have access to things on the 77 network (such as my NAS and printers), but will be constrained to the

    parental rules set in place on the 78 network....

    Setup will take about an hour, this includes unboxing, installation, registration with OpenDNS, setting up router, and clients.

    The most novice of network users can do this to secure one network while leaving the other intact.

    Ok.. yes its 44$ that you might not have, but just about the most effective way to lock down kids, without screwing up yourself.

    I did not see this Post, until after the fact I added mine. But, I do not agree about the search engine keyword filter. But, I do agree that OPENDNS is a awesome, but they really do need to add an Automatic Categorization on Keywords located in the Web Address or Domain...

    For example WWW.PORNHUB.COM has been on the categorize and tag listing for over a year or more, and it is still not categorized as a Pornographic Site. Why is that? I know for a fact that I have categorized it around 10 or 12 times, but it still is not in a category.

    This is what I would like to see happen, because it would possibly, categorize hundreds if not thousands of pornographic sites, simply by the keywords found in their Web Address, or Domain name..

    As for the Problem that Tuckson is having, simply do what I have done here at my home. I have blocked all search engines. Along with the categories that I have selected, my network is very protected from pornographic material. Of course you are never going to block everything, as you can see by example, that www.pornhub.com wasn't blocked under the PORNOGRAPHY category, because it hasn't been classified or categorized. Go. Figure that one!. So, I added it to the blacklist along with the other 10 or so that I have found.
    I have 3 teenage boys, and if it wasn't for OpenDNS, my water bill would be over 150.00 a month from all the showers. ;)

    This is because you raise false facts.  It is clearly categorized since ions already (March 2008): https://domain.opendns.com/pornhub.com

    What do you mean by "allowed" and why do you think it shouldn't be allowed?

    I am assuming that you are an OpenDNS user and that your account and network are properly configured to use OpenDNS. Is the domain properly categorized? Is that category one of the categories you are blocking? If no to either of these questions have you added it to your blacklist?

    @markjc2002   All you need to is to add "Video Sharing" to your blocked categories, or  "aways block" "vimeo.com" can do that through your "Manage individual domains" options.

    So the answer to "WHY"?" is that YOU ALLOWED IT.
