Proxies

I once knew someone who made proxies that booted from flash drives, and they did exactly what the online proxies do. I was sitting next to a kid who bought one and was able to get on facebook while we were supposed to be researching for an English project.

Well I know one too, and his program just connects to other proxies and tunnels all connections through itself. So it's not quite a proxy server, just a proxy-to-proxy (like C++ pointer to pointer)

So it's not really anything worth looking into since I can access proxies online.

You could download the Tor browser bundle and put them on a flash drive. Tor is effectively a proxy of sorts. (It's more like a network of proxies).

Is there a proxy that allows cookies? I can't access facebook for homework help without cookies.

Feb 9, 2012 at 5:51pm

I think you might be able to enable cookies in the browser.

I have cookies enabled. For some reason hidemyass.com doesn't have cookies, so I can't access it.

@ GRex2595: You're thinking about this in the wrong direction.

OBJECTIVE: To access website X.

PROBLEM: Your school has a proxy in place that redirects access to website X. Also your school will likley be recording any websites you go to including the proxy sites that you are mentioning, this could lead to trouble which can be avoided.

TECHNICAL INFO: A proxy filter like the one your school has is a SETTING for the browser which is often set by a network policy. You need administrator privliges to change this, which is something you do not have and would be more trouble then it is worth for you to obtain.

SOLUTION: Bypass the browser, there by taking the network proxy out of play: http://portableapps.com/apps/internet/firefox_portable enjoy.

NOTE: This is certainly a violation of your schools computer use policy so you should review that, and as always, weigh the costs and risks of your actions against the benefits. Remeber that costs are incured on purchase and benefits are never guaranteed. Also I am only helping you with this stuff to encourage the motivation that I see, the minute you start getting lazy I stop helping.

At both of the schools I've used the computers at, you couldn't run executables that weren't explicitly allowed.

So if I were to use google chrome's portable version, I'd be able to bypass the redirection? My next question is how exactly does that work when it's embedded into the network, everyone who has access to the school's internet is unable to go anywhere that's blocked without using the admin connection, which I don't know how to get codes for if I wanted to. Unfortunately for me, I want to learn everything I can about computers including stuff like this, but I don't have a clue where to start.

EDIT: I missed part of the technical info, so my guess that it was embedded within the connection is probably incorrect. Sorry.

Hmm... if you have a WiFi device and your school has WiFi, try connecting to it (should be your usual username/password) and seeing if any websites are blocked. If so, it could be that the blocking software lives on the router(s), which you won't be able to get around because all network traffic goes through the router(s).

@chrisname: I doubt it's actual software blocking access to these sites because the OP already said he can hit external proxies, which is something software would be able to block. This is probably a simple local DNS redirect, ARP entry poison maybe even a simple host file entry.

I'm on a desktop that is connected with a cable, so I don't think it has wireless capability. Even if it does have wireless capability, I don't have any way of accessing it without the password, which I don't have.

If it's any help. I'm being blocked by St. Bernard iPrism

I don't think so, I think it's software that blacklists certain sites. My school has one, as did the school I used to go to, and in both cases there were certain sites (including proxy sites) that we could still access sometimes. Eventually they would be blacklisted and we'd have to find new ones.

I wondered about setting up my own relay but never got around to it.

Wow!!! I've been a real sysadmin for so long that I didn't realize people still used that stuff! I remember the one from my high school, it was called BES. The retarded chocalate lab is what kick started my interest in this stuff, back then I would rather have been kicked in the face then told no by an adult (yes I was kind of a punk).

@ OP: Can we get a dump of the running processes on that box? start->run->cmd->"tasklist > Tasks.txt" then copy paste the contents of "Tasks.txt". It's either running as a service in the background or more likely as an add-on for IE. Either way the portable application would still be a solution if you launch it from a thumb drive but if you run into the "white list" scenario that chrisname menitoned his schools had we would need to rethink this a bit.

EDIT: @ chrisname: In regards to your thoughts of launching a proxy of your own, just don't make it public. Otherwise you run into liability issues with anything that other people might be using it for.

The software was running on the school's servers, not on the workstations. Plus, cmd and so on were disabled on normal accounts.

Feb 9, 2012 at 6:54pm

If cmd is blocked, which is likely, then try making a batch file. Open notepad.exe, type tasklist > Tasks.txt into it and save it as NAME.bat. Let me know if this works, we are by no means out of options. EDIT: If it turns out that filter software is running on a central server then it won't be able to see any portable applications you launch so we're right back to my origional solution.

@chrisname: Where the heck did you go to school? Father Baker? Crackdowns like that don't usually happen until someone makes the Sys Admin look like a joke. I feel the need to ask, was it you? If so is the statute of limitations up?
