After reading the dig article "Kids Outsmart Web Filters" which links to a CNet News Article . I was wondering what measures you have used or know that have been used to bypass internet filters. I have the sole interest of securing internet access in my schools.
Thanks guys!

  • I cant believe no one has said to connect to a remote linux box through xserver and view websites from there. xserver ports are blocked you say? change the config on your linux server to run xserver on port 80 :-). Even the admins asked me how i did this, … Read More

I've heard of lots of different ways. Proxies being the easiest and most prevelent way to do it. But it is simple to ban all proxies from being accessed. I read through all of the replys to the dig article and there are lots of ingenous responses, but i was wondering if there were any others that daniweb's people know about that not many others do.

When I was in the army, they had filters. The problem I had wasn't that I wanted to look at porn or anything silly, but that even legit e-mail sites were locked out. Being a programmer, with access to a linux box that was outside of the network, I wrote a perl script that allowed me to type in the URL, and it used the LWP module to retrieve the HTML, added a base tag to the HTML (to expand all relative paths) and modified the links so that it referenced my perl program, so that it could get the HTML for the HREF'd page, and saved the HTML file on to the server (the linux box running perl, which was also a web-server). I suppose the concept is a proxy, but when someone can program, you have just lost over half of your power to lock them out of things.

hehe...in my school the internet security was simple (that was long time ago, like 5 years). We were not allowed to use forums, look at porn, write email, and go to controversial websites, and play games. Security? Two old ladies ran around the computer lab looking over everybody's shoulder trying to see if they were doing anything wrong. Given their illiteracy, I was caught and warned many times for programming in C++, and VB (they did not even know what it was, but if they dont know, its illegal). Having a DOS window (to run some program), got me yelled at many times. Ahh...the good old days.

yep proxies thats how we do it. We set up a php proxy and someone hosted it. Are school blocked stuff randomly like CNN. Then they made it so you couldn't change the proxy but we went into the registry and edited the actual value or ran live linux and changed the proxy in there. You can also use firefox.

Watch out at my school people get banned for that usb flash drives are better. We ran Quake III off of a cd. We took the installed files and copyed em to a cd

Doesn't matter if they ban proxies. Chances are they already have. If you access it via a secure connection then there's nothing they can do about it.

www.proxify.com will be blocked by the filter, but if you type:

https://proxify.com then it will work perfectly.

for IE go to tools->internet options->connections->lan settings-> x the box to use a proxy and enter the ip for that proxy and port prob. 8080 or 80 for http

You can also set proxy options in the tools/option menu to some ip address that allows it. That way you don't have to constantly go through proxify. There is also a way to edit the URL to include a specific port number or something, but I don't remember how to do it.

Your way didn't work for proxify.

they blocked the use of proxies and our school. Basically any unkownd ip address is blocked and they block all but non essential ports. I don't really use proxies at school becasue the main thing I used them for was games but now that we run live versions of quake off of cds I don't care.

Yea I tried to change the proxy by going into lan setting and putting in a proxy, but it didn't work. Our Computer Specialist is really cool and he teaches us a lot about computers and he told me that our school(s) in our city disable the changing of the proxy. But he said I could use one in there. He mentioned something about the web interface I need to ask him more, but does anyone know how i could do this? He said that there we are bunch of them. He wants to see if I can figure it out.

If you allow traffic out on TCP 443, here's one way of bypassing your proxy. I've been doing this for awhile now. Of course, it's just a matter of finding out which ports are blocked from the inside and finding one that's open in the event 443 is closed, but you get the idea.

I could also do ARP spoofing, IP spoofing, or a number of different things to get around it, depending on how you've implemented it.

Well I'm sure ya all kno how to bypass the Google Images filter and such without using a proxy.

1) Google.de

2) Now, go to advanced settings, and set the main language back to english

3) search pictures away :)

Then again, our WebSense filter's pretty lax anyways...

I think that is pretty sad that schools block google images. They did at our school too. They blocked the homepage of wikipedia once! It is pretty sad, but I guess you have to block the retarded kids from looking at pron at school. The school also gets money from the government if they put filters in.

They dont get money for filtering it, they are protecting their asses by doing it. If a parent decides to sue a school becasue their child looked at porn there, they would win. This is why filters are used. Its just to protect them from lawsuits.

Hmmm, actually I thought they got some E-rate funding or something to help pay for internet and computers, but maybe I am wrong.

Actually only some school districts can get government funding for technology. Most, have to supply most of it on their own from towns taxes.

i had a nice system hardware lockout's that you cannot change anything proxy's and software firewalls and content protection systems download restritions checkpoint firewalls you think of it we had it and i got arround it! using these steps!

1.Got a CGI proxy that was using SSL which the content filter didn't see as well as the download filter!
2.Downloaded portable firefox now i had the web unlocked for me!
3.i was a restriced user and there were no cd drives and floppy's were locked!
4.i broke the SAM for the ADMIN by grabbing it and the syskey in the repair DIR!
5. It took a while even with ranbow tables but i cracked it!
that was level one
Now i hacked into the webserver's password! and from there it's another very long story but in short i got the sql records for all the accounts.......... and found the admin...... and broke free!

I guess we won't be hearing from you in a while. I hope you like the pen.

Oh, as for students like us. Who are not so well versed with technologies. We usually get the IP address of the website and paste it into the browser to surf. It works almost all the time.

Web URLs and their names don't change. IP might change although rare. So proxies block the names rather than their IPs!

right, but aren't the hyperlinks jacked? Like if the link references the same domain, but a different page?
