Filter out inappropriate websites

ok, i have been asked to get some software to Filter out inappropriate websites!! Any suggestions? I know of net nanny but other than that i don't really know where to begin...

any thoughts or suggestions woul dbe great,

thanks

I started to mess with this long time ago, but abandoned that
when I realized the user can always detect and close the program
using the Task Manager. I had the program already blocking
certain websites (according to their URL) by closing the browser
window if it detected such website active.
as for full scale software sorry, not familiar with any...

ah right, well if it is easy to close then it is not worth the money as it will be difficult enough to stop them trying to hack into it anyway. Let alone if they can just turn it off..

thanks SW

the company i'm working for has something on/in their browers (company wide) that prevents the user from going to certain websites (lots actually) ... it redirects them to another page that says basically ... "You should be working, stop playing on the Internet" ... not really sure how they do it though. Luckily I don't have one of their regular desktops and don't go through their network, so I can still play.

i know i can do it on my router so that if they type anything like xxx or porn in then it will send them to a page say NO! but the person who wants this software doesn't have a router...

in theory, I can mask my program by giving it name resembling
system name - it would fool most users, even veterans. however
more "advanced" users will still be able to detect it and kill it.
if only I found out how to make process re-open itself once killed
(or better yet, cause Restart) I could proceed with that program.

My teacher created an awesome program for our library. There are actually two programs, and it somehow makes itself a service and does something to attach to Window's internal thing, I couldn't really tell, but he's a smart guy and he did it with VB6, at which I tried to decompile and of course failed miserably lol

But I believe that he placed a timer on each program, if one of them died, then it would restart the other.

As for the internet filter, it occurs I believe when data hits port 80 on the central internet router for the school, but I could be wrong.

Isn't there a trick for using the lmhosts file?

Can't rememeber the details at the minute though.

reading all this and thinking about it more if tehre is a program on there at the end of the day they will find a way of turning it off. I think he wants to network the computers at some point so i will just suggest my router to him and say i can block things from tehre!

thanks all,

the company I work for runs WebSense on their ISA Server to filter all internal surfing. It is configurable using group policy...and allows for exceptions!

Pain in the arse that thing. Works far too well!
