Proxies

Hey I was wandering is it possible to have a proxy on an offline pages because the proxies at school don't scan pages that are offline so i could use a proxy if it was offline (all the others are filtered out)
If it is possible how would i do this?

When you say offline pages do you mean pages that the browser has placed in a cache and are accessible with "With Offline" checked or do you mean something else?

I think he means that he wants a proxy he can run on his computer at school that will channel all his web browsing, and thus get past the schools proxy server.

In short, it won't work. The reason web proxys do work is because they intercept the packets travelling to your computer and make them look like something they should (i.e. Google) instead of something they shouldn't (i.e. Games). If you run the proxy on your computer, it can't intercept it before it gets to the school's proxy.

However, SSH tunneling (search for it) might work, depending on how smart your computer technicians are. It will all depend on if you can find an all-port SSH server, and which ports your technicians left open.

Hope I've helped.

I once experimented with some software that was supposed to encrypt the data going between the computer and the internet. That way the data couldn't be screened and blocked by any of the school computers I never got it too work. Then one day I found a for pay proxy that sent the data through a https connection so that it was all nice and encrypted. But it was like $50 a month and all it would take is the school admins blocking that main address to stop it from working, there goes $50 down the drain. So basically you can't get through the proxies at school, and you shouldn't try. At my school just trying can get you banned from the internet and ISS(in school suspension).

There are several tutorials online that show how to set up a SSH and proxy server with your own computer, and then just take Portable FireFox along with puTTY to school to connect.

If your school charges for Internet usage, then they probably only monitor what is actually being transfered, with the HTTP request packets going unmodified (e.g. if you are out of credit, you will still be able to send a HTTP request, but the actual contents of the page will be filtered out). If this is the case, then look into something called IP over HTTP, tunnel your SSH connection over your home HTTP server, which then connects to your home proxy.

I was already caught and punished for this in my second to last year of high school, then decided there wasn't much point in continuing in my last year because:
- Assignments became tougher and every minute spent at school there was something to do.
- $20 every 3 months for more credit wasn't really that much.

Hem no, my school doesn't charge for internet use, my teckies are dum as hell, when my house master sent my laptop to be checked (He does routeanly because he thinks i'm some sort of crazy hacker), they had to call me to show them how to boot into windows (I had a linux live disk in). They don't administer there servers themselves, they buy in programs to do it, proxies do work you just have to find one that isn't blocked and there are free proxies.
Thanks for the sujestions i'l look into them.
Thanks,
Jules

I would have removed Windows from my GRUB menu and so they have to boot into Linux, and remove X from automatically starting, and KDE from starting with X.

He can do that? I'd tell him to go to hell.

Wow. So they only check your Windows setup? What would prevent you from keeping all your files under an encrypted Linux partition?

Our school's system blocks any executable that isn't first permitted by them.

The only ports we can use are port 80 (I write some networking apps during class, such as my game).

We aren't allowed to use our own laptops on the school network.

In our elementary school, there are no charges for using the net. Something like DDoSing websites or networking with their laptops... err, the little pupils even didn't know what's networking, neither what is GRUB or Linux. They know how to turn the PC on, search things on the net, and play games. Or watch... the more spicy stuff

[not on the PC though, especially not on the school one

...]. That's all.

Also interesting things you can find in our school, ranging from 80386 PC w/ no PnP, to the 5,25" floppy drive. Also four 25year old (mostly damaged) cheap-o portable turntables, some reel-to-reel recorders from 1980, maybe a PMD-85 somewhere forgotten in the trash, manuals for various things more than 20 years old etc. Many things are in dust for more than 10 years there, and are rare to find
