Very well demonstrated and I have to give you credit where its deserved. Nice tutorial for the high-school or common worker were access can sometimes be limited.

2. yourwar - May 18, 2006

Thanks! Complement are always taken with open arms haha. It’s a critical world and when you get good criticism it helps motivate you! Anyway, thanks again!

Great tutorial, the problem with ultraVNC is that it doesn’t provide any encryption natively, you have to install a third-party plugin to make your communication secure.. I think the link to this plugin is on the ultra VNC’s website.

You should also give out a few indications about port fowarding on a hardware firewall, or how to open port on your XP installation to let the traffic destined for your computer to pass through.

Just don’t be too suprised if it doesn’t work at many workplaces. Port restriction runs rampant with many a network admin.

5. Warren - May 19, 2006

Very good tips. Of course, if your school is running Novel and you’re interested in running executables off of a jump drive, try renaming the file to ‘notepad.exe’. Since it’s a Windows required file name, Novel should allow you to execute it.

If that doesn’t work, you can always use the Linux backend that’s built into the Novel clients to mount your iPod and grab the SAM files… I mean… don’t do that, it’s bad…

6. James - May 19, 2006

Cool stuff. But don’t most high schools block you running your own .exe? Mine does and because I tried portable Firefox off a USB stick once and it just said I didn’t have permission to run that file.

7. DoubleYouSee - May 19, 2006

As a Highschool Tech in Canada, assigned by the board to this school (not a teacher :D) I can tell you that the scope of this artical is pretty narrow. First off, you have to assume that the school (or board) isn’t blocking VNC… and of course ANY tech worth his salt knows about VNC and knows the ports to block to prevent access…

That said, if you can get through, and your schools browser alows java applets, run Real VNC and use the web access port (5800), no USB key required 🙂

Cheers!

btw: our Board has central internet provision (and thus firewalling), I’m the tech at this school but even I can’t connect remotely to my home PC… without SSH 😉

8. Eric - May 19, 2006

Good tutorial, I already do this. However, you might want to do a tutorial about using Hamachi or SSH tunnelling to encrypt the connection end to end so you don’t have an open VNC connection on the internet that could be hacked (new VNC vulnerabilities).

It will suck when they disable usb drives on your PC’s.

You’re at school remember? Screwing around on myspace isn’t exactly what I would call learning.

10. Mister Shiney - May 19, 2006

This is an interesting method, but one problem is all of your vnc traffic is sent unencrypted over the internet. Meaning it is trivial for anyone on the internet (or your school’s network) to see everything that is exchanged. To avoid this problem, take advantage of UltraVNC’s support for encryption plugins. There’s a whole bunch of plugins available (most in beta) that will encrypt the traffic being sent through vnc.

11. Rich - May 19, 2006

Don’t you need a static ip on your home computer for this to work?

12. Warren - May 19, 2006

Not if you use a free service like DynDNS

13. heliosphan - May 19, 2006

What a great tool and good job on the thorough instructions!

14. Chris - May 19, 2006

We used to do this for a while when I was at school with VNC. Problem was, they started port blocking everything, and that was the end of that.

15. Steve Brown - May 19, 2006

Yeah, we have really hard restrictions at our school. For months, they block the internet totally. No websites work. And when you need to use it in lessons you the teacher has to go to them to ask them to turn it back on for their group only. We also have exe blocking, etc.

But what I discovered was that if you start logging into Windows, but as soon as the logon box goes, disconnect the nextwork cable, it says “your settings/whatever could not be loaded, etc”. It then procedes to log you on with Admin privilages. A little bit of network sniffing then revealed the proxy that the teachers used to access the internet (they have an unfiltered one). Still, I go no further. But now I can play DOOM in form 🙂

16. yourwar - May 19, 2006

LoL, very cool Steve. I’m gonna have to try that lil cable unplug tool today.

17. bubi73 - May 19, 2006

Port Blocking is a very popular means in some workplaces (such as mine) to prevent VNC connections. For some (incl me) the above approach does not work at all. I currently use the free service from http://www.logmein.com which lets me access my home computer through my browser and can’t be picked up by my company’s port blocking software. Also, lgmein claims that transmissions are secure (128 bit) and the overall process from setup to actual using is very easy.

The only drawback is that file transfers are disabled in the free version, but I usually email files to my hotmail acct and then retrieve them from my work computer (of course all of my important files are encrypted on my home computer!)

18. Hawk - May 19, 2006

UltraVNC is crap! Use Real VNC.

19. Oracle - May 19, 2006

you could just use Remote Desktop Connection, default with windows.

just enable it at home, and open the ports.

too access it at school create a desktop schortcut linking to
mstsc /console /v IP:PORT
*remove the /console if you want to start a new user session isntead of working with curent*

and if that doesnt work, you might be able to copy RDP to a USB stick and use it off that. RDP is also WAY!! faster than VNC.

21. iSEPIC - May 19, 2006

ugh, why go through all the hassle and risk (risk that they block port 5800/5900, or risk they won’t allow the exe to execute) when all you have to do is enable Remote Desktop Protocol (RDP) on your XP Pro and change the port to port 80— unless they whitelist (e.g. block everything but what is on the whitelist) then more than liekly you’ll not be blocked. Also, if you enable IIS, you can connect to your RDP home computer via just a web browser, but most installs have a client version of RDP so you should be fine either way just connect to 0.0.0.0:80 or whatever port you want to use – silly to use the default 3389 because it more than likely will be blocked if you are having to go though all of this.. best of all, it’s encrypted, and you get sound!

22. Shree - May 19, 2006

How about using Services like Logmein GotomyPC myIVO..

These will take away most of the limitations discussed above..
Like port Blocking, These will operate on a Standard Port 80 via a Web Browser and are Secure…

23. Oracle - May 19, 2006

You might also want to chuck a port scanner on the USB stick to see what ports are open.

24. John - May 19, 2006

Some network administrators may be a step ahead of you. On my network, I prevent students from running programs (.exe, .bat, .com, .vbs, etc.) from all locations except the ones I specify. So programs can’t be run from USB keys, the desktop, Web sites, or any other location I haven’t explicitely allowed.

And the locations I do allow programs to be run from, students don’t have Write permissions to–so they can’t drop files in those directories.

Sorry!

25. Oracle - May 19, 2006

if kids wanted there freedom so badly, they would get a bootable NTFS4DOS disk, and just change the admn password in the SAM file, and theyll have full access

26. Alan - May 19, 2006

The cable unplug trick is one we used to use. The problem is most english schools have out bound port filtering. If this is the case like my old school then you will have to find out what ports are open, port 80 (http) is usually open, sometimes 21 (ftp) and at our college 22 (ssh) was open. I have a linux machine setup here – so I used openssh client putty at school to tunnel connections for other blocked ports out, including tunneling to my home proxy server to allow game sites, msn web messenger etc and vnc to it. Have fun but dont get caught folks.

27. yourwar - May 19, 2006

Well yeah there is other ways. You can run knoppix bootable disk and do the same thing with the SAM file, but you would get uber fucked if you got caught.

This is just 1 way out of the many and yes, it won’t work for everyone but it will for some. Those who it helps, I am glad to have been of service and I hope you enjoyed the article!

28. winguez - May 19, 2006

I’m with 17. Based on your network speed at home, and connection through work, lomein.com is a great app. It allows you to browse and control every part of your home PC environment.

Viewing pics and other video elements is not something you do through this app. It is handy and free for the most part. It does require you to install some software.

29. nick - May 19, 2006

I am all for thinking outside the box, and doing your own thing. I think this post is very useful for non-PC people, when the situation warrants remote PC usage.

However, a highschool network is very rarely ever the situation in question.

I worked as a systems admin for a large school board for a number of years, actually it was the highschool I also attended as a student. From the student perspective, it’s about limits and rules and being punshied for being a teen. I totally felt that. Why should the school board impede my computing experience in any way/shape or form?

On the other side, from a tech perspective, I found out why in a hurry. Myspace.com was one of your examples, and it’s a wonderful site… when used properly. There’s also a lot of absolute garbage there as well. The number of parents and teachers that have come forward and complained, and sometimes ~sued~ the school board for “allowing minors to access inappropriate material” is ridiculous. Absolute lunacy.
So here’s where the school board comes from with it’s limits:
These PCs were paid for by you and your parents and your parent’s friends via tax dollars. They were bought for one single purpose… guided academic learning. Not just learning in general, and not just random academic learning, but specifically guided academic learning.

In my experience 75% of the student body is there to use the PCs in a legitimate fashion. 25% is there to violate, hack, or otherwise tear down the network. Those restrictions are in place to keep the 25% from stopping the progress of the other 75%. If those 25% suddenly evaporated or otherwise disappeared, most of the restrictions would also disappear.

It got so bad that we had to go with NetSupport School (a wicked package, but evil in the eyes of the students).

Sorry kids, but you’re there to learn and that’s about it. If you want to mess around, go home.

32. John - May 19, 2006

The boot disk option, just like the USB key option, won’t work on a machine that has been properly locked down by a sysadmin. On my network, I don’t allow boots from USB keys, CD’s, diskettes, or anything other than the hard drive. This is configured in the BIOS, which in turn is locked with a password that’s a random combination of letters, numbers, and special characters.

33. HA - May 19, 2006

Ok kid there is a MUCH MUCH better way to do this, and it doesn’t involve a thumb drive!!! Just set up a proxy server on your home computer……. If you don’t know how check the wiki….. Then get on any computer at your school work etc… and open internet explorer, go to tools, internet options, connections, and lan settings. Then us the IP address of the computer at your home as the proxy server…. Not that hard is it now????

34. elusid - May 19, 2006

I’m at a workstation that has access to local drives disabled. So no access to thumb drives. One way around this is just upload all these EXE’s to a personal web server and execute them off the server. That way you can access them from any internet computer and avoid any questions asked about your thumb driving poking out of the PC.

35. Mike K - May 19, 2006

If you are able to do this with VNC or remote desktop, then you are really, really lucky! These are usually blocked, and even if you have them listen on a common port (such as 80), they can still be blocked. A web-based proxy server (like SSL Explorer) would be a better way to do this, since it is highly unlikely they will block port 443 (required for https). Once you establish that connection with your browser you should be able to tunnel ALL traffic back through your home PC. No need for a thumb drive, just internet access. One caveat, though – this requires Java and depending on how locked down the systems are you may not be able to get through this.

36. JAK - May 19, 2006

Excellent article for non-techies. However, this only works until your company/school remotely sniffs the ports you’re using due to “steaming video” activity. Then they’ll just shut off the port that VNC uses.. For a techie, this is farily simple to overcome, but to a non-techie, they’ll just be like “oh. well that sucks.”

Or, even worse, the network admin at the school was smart and has remote access to the computer you’re using at school, like at my High School right before I graduated 5 years ago. He’ll just shut down your VNC session, or even worse just come over and proceed to report you.

Also, with this method, you risk having keys logged, which is sometimes even stated when you log on to the computer.

If none of this is in place, then your network admin either 1.) needs more staff to deal with the “lesser” evils of the network so he can deal with things like this or 2.) isn’t worth what he’s being paid, at all. It’s a huge liability issue.

37. Kano$$ - May 19, 2006

Thank you god, i hate how schools block some stuff that isnt even “adult Content” For instance … graffiti website. I myslef enjoy graffiti and like to watch videos and other things, but school says it is “adult Content. Thats a fucking lie right there

38. paulie - May 19, 2006

This will work somewhat well if you have a retard for a sysadmin.

39. thatguy - May 19, 2006

In most of the schools I work with the only way out of the network is through a proxy on port 80 and 443, and they log every click by user name. Kids were using remote proxies for a while untill they changed the AUP to state that any method to bypass the schools filters was tantamount to accessing porn. They use real time monitoring programs to parse the log files during heavy use and can remote into machines without students knowing. If a site is found or IP address for proxy out they grep the last 30 days of log files for any accesses by students. They then output the logs to a file and send them to the building administrators. So watch out, not all school networks are wide open and not all school admins are chumps.

40. GWBush - May 19, 2006

RE Comment 24: Agree. The SA just disables exacutable files from running on USB drives. Can do this with Group Policy or with a freeware program like Trust No Exe. Sorry. If you want to screw around on the coumpter, do it at home. Why don’t you try reading a book instead?

44. TIM THE HACKER - May 19, 2006

Ummm yeah VNC is a good tool for remote desktop. Especially on public PC (Such as school which I am at now) But if you are trying to access restricted web sites and stuff you may want to go a different route. Essentially what you are doing is connecting to your personal computer so that you can go to restricted sites. This is basically a proxy. A proxy allows you to connect to another computer and use their Internet connection. By using a proxy you do not have to host a VNC server always, maintain it and keep your computer running so that you can use it. If you are using Internet Explorer (Which most of you are.) Click the tab at the top that says Tools. Then go to Internet options. Click the connection tab and then go to LAN settings. Then click the box under proxy settings. Then you enter the IP of the server that is hosting a proxy. I recommend using codeen. This method is a lot simpler and you have a smaller chance of getting caught. Plus, the staff will not see a whole different desktop window. Good method yeah…

45. yourwar - May 19, 2006

Maybe I’m just lucky, but the sysadmins and staff at my school are totally ignorant, lol.

46. Network Guy - May 19, 2006

————-
I know I hate getting onto ANY computer that tells ME what I can and cannot do. I mean aren’t we the humans?
————–
Kids kids kids. The reason computers are telling you what you can and can’t do is that it saves the school districts money. A school district that saves money passes that on to its local population in lower taxes. Lower taxes mean more money for things you actually like, like music, books, sporting events, and other stuff. When you are busy trying to circumvent all of that stuff then you end up giving someone else a job. They get to keep shutting down newly created ways of getting in/out.

Let’s put this in numbers you can better understand… the school district I was part of two years ago raised our tax rates by 13% or $650. As I’m sure you can imagine, that can buy a lot of stuff. Food, clothing, vacations, etc. So rather than let you kids get a better education, go on a field trip, etc, I’m funding some person hunting people down on the network.

47. LOL - May 19, 2006

Well, the article is okay. A bit immiture, but has a good grasp on the average user, helping them through the steps A – Z. So, congrats on the article…

However, notice if your school is equiped enough to “knock off” the latest website, and kill your favorite search terms, they will with out a doubt have egress filtering, or port block. There is no way any network admin would allow 5900 going out, for far too many reasons. Chances are good, only HTTP (80) HTTPS (81, 8080, 443) and possible if you are lucky FTP (20, 21). Although I am seeing FTP be restricted more and more. Point being, this will work, if and only if you run it on a port which is unblocked. So running it on 80, or 443 might not be a bad idea. Just watch it, some ISP’s block you from using port 80, or other common service ports.

Also, think about using SSH, not only for secure remote access, but for tunneling as well, you can tunnel all traffic, and not worry about the skimpy background you have on your home computer, you will still be using the schools system. You could even tunnel your VNC session, keeping any “nice” network admins from picking up the traffic, and your passwords….

48. CrazyShrum - May 19, 2006

http://www.w00ttech.com/node/5

This is how we get around the port blocking, and web browesing. All you would need to do is be able to run puTTy and find a port that is open to run SSH through.

53. Mike - May 19, 2006

I restrict PCs for a major University. This should not work on any computer set up by someone worth their pay. We do not allow executables to be run from any removable media.

Using a web browser to access the java client as Matt said would work though. And we have no problem with this. Restriction for us are not about blocking access to websites (we don’t restrict web access at all and likely never will), it’s about keeping our PCs reliable, and preventing them from being used for malicious purposes such as spambots, network sniffers, etc.

Remember that a school computer and network are not the same as your property. The bodies that allow you to use them have every right to tell you how you can use them.

My feeling is that in a high school if they catch you doing this they are going to suspend or expell you anyway. The policy probably is not restricted to “hacking” the PC, but extends to using the computer for inappropriate use; which is a catch-all for anything they don’t want you doing.

Good luck,

Mike

54. AK - May 19, 2006

SSH tunnel software is a huge caveat that should be mentioned in the article. I’d hate to find out that all of the posters above who DON’T use SSH tunnel software above or know what it is are logging into their home pcs and checking bank statements, using passwords, sending important email, etc. It’s a huge risk.

55. LOL - May 19, 2006

Matt, port 5900 is for the viewer, whereas 5800, is the Java connection.

Again, yes SSH tunneling is the way to go here.

Agreed, this will still get you in as much trouble…

56. PC - May 19, 2006

As an admin at a school system, I have to say: “These blocks are there for a reason”
If the streaming a/v sites weren’t blocked, all the bandwidth goes to kids surfing them instead of doing work.
Some places will use VNC for helpdesk admin, as it allows you to show someone exactly what to do at a different site, however most of us use remote desktop. Depending on your school computer/net use policy, getting discovered using this method would result in termination of your account, and loss of privelages for the duration of the year.
At a “work” envrionment, you can be fired for that.
If you’re not allowed, it’s for a good reason.
If you are allowed right now, it’s only beacuase no one has happened to catch you.
I’ve worked in places where the only things on the comptuer that were open, were the things needed for our jobs. The main app, and IE for scheduling. If you tried to change IE settings, you weren’t allowed. If you tried to run from a usb key/CDROM, you weren’t allowed. There was no Explorer shell. the shell was the main app, and it had a schedulin button that launched the IE page.

Also, in our school, there’s no proxy set in IE, it’s done at the router level, all requests from port 80 go through a main proxy.
Also, we’re implimenting a hosts file based DNS posioning for inappropiate sites.

There’s no reason for kids to go to school these days and look up pron/tasteless stuff. Most have ‘net connections at home or can go to a friend’s place enough, or have a laptop and have free wifi somewhere in your area.
You’re at school to learn, but not to learn pron/hax0ring. Do that on your own time, with your own bandwidth.

60. Chad - May 19, 2006

ok, first off Ultra and Real VNC suck,. Use TightVNC for better performance. Do what the above says, and just use your browser. If you are worried about a certain port being blocked, thats fine. Just change it to an open on the server. Then, instead of the 5800 (5800 for web, 5900 for vnc viewer) change it to whatever you know is already open. Talk about making an easy proccess complicated!

Do you really think that they are secure? Oh wait, it says so right on thier website. We caught one of our users trying to access his home computer through this site. His personal computer was on an untrusted network. Therefore his work computer was wiped and rebuilt. His account was also terminated.

62. Invartact - May 19, 2006

The techies at our school are complete jerks about everything. I can understand some of the sites blocked…cuz I can get around any of them thanks to proxys and I can understand blocking some executables and such. The problem occurs when your class is caught messing with the entire network at your school and the tech guy has to reimage all the computers.When this happened to me and what is the first thing I do…install firefox. The thing I didnt know was that they were watching us cuz we had messed with them before. I got 2 weeks of In School Suspension (ISS) for installing firefox on a school computer…where is the logic there? Thats right, its not there and they are just trying to get people in trouble. I was logged into a differnt server and I changed a ton of files to allow more access when I logged into my account…but thats not the point. Why cant the tech people just block pr0n and maybe .exe, .bat etc etc etc

63. Mike - May 19, 2006

Hey Dude,

Ive done that so many times, nut to let you know, the admins know exactly what your are doing. Most schools monitor the outgoing and incomminf connections. However, if your conncetion is deemed suspicious, (like mine was one day), the server or proxy beem and immediately notifies the administrator. There the admin can judge from what going on and get you in trouble. Trust me this happened to me and it was not pretty afterwards.

64. Simon - May 19, 2006

The easiest way to “bypass” the filters at school/work is to upload this PHP script to your server:

When I was at school, I created something that encoded all url’s using base64_encode, so that they wouldn’t be picked up by the filters. Couple that with image caching, and you have your very own web based proxy. 🙂

65. Simon - May 19, 2006

Ok, you can’t include PHP in the comments…

include(“urlhere”);

Just add the PHP start/end tags around it. (Hopefully it’ll display this time…)

Any machine that’s properly locked down will prevent you from changing IE’s options (to point to a proxy server, for example).

I really can’t be too critical of school districts that don’t have properly-locked-down machines, because it wasn’t so long ago that we were in the same boat. It has really just been within the past year or so that I’ve leveraged GPO to block all of the tricks that I’ve seen posted here. Being a sysadmin at a school district isn’t like being a sysadmin at a Fortune 500 company; we often can’t afford good training or technology, and we generally have to wear multiple hats.

But after reading the methods on this blog, I feel pretty good about the measures I’ve taken to lock our system down. They stop pretty much all of them.

John, can you stop SSH tunneling, on a open port, like port 80?

Cool stuff. But don’t most high schools block you running your own .exe? Mine does and because I tried portable Firefox off a USB stick once and it just said I didn’t have permission to run that file.

Same here. I hate IE, and the school forces us to use it. To get revenge, I just change the comments in the properties of the shortcut so that when you mouseover it talks about how IE is no good. I’ll have to try this some time.

77. Dathker - May 19, 2006

it would work if you had an adminstrator that doesn’t really care about what you do as long as it’s not pron, etc., but some admins block all ports except 80, and filter that.

78. teh funkytommyman - May 19, 2006

wtf???? any 1337 pwer haxx0r would know a way betyter way. instead of doing all that, if you already have the usb drive, just install linux on it and boot off the usb instead…….. or you can do a WIN repair and go all backdoor by pressing shift fsumthin at the “installing devices” to acces the dos promt to open the admin password reset box

I think all the network admins should go fuck themselves and rot in hell. And school isn’t about learning. It’s about a bunch of assholes making kids take tests and do projects and shit.

This is not going to work for the host server behind a NAT router. In addition, if you are using DHCP for your host server, it is not prone to failure, once a different IP has been dynamically assigned to your computer.

81. Piranha - May 19, 2006

Guess what, I WORK in a school district’s IT department. You don’t have a right to do “what you want” whenever you want. You don’t own the system, and just like you can’t bring a gun to school (whether you are 18 or not) you can’t do whatever you feel like.

Why?

#1. Kids CHEAT using instant messanger programs, share answers to tests, share questions to tests, and whatever we haven’t uncovered yet.

#2. Kids go to game sites, myspace.com, and other websites that teachers don’t want them to be at and have nothing to do with learning. You’re in school, screw around on your own time.

#3. Kids hack our servers, and try to find any loopholes and exploits possible.

As a “victim,” you’re lucky you even HAVE access to a machine that can run the internet, some school systems don’t even have internet access. Some are still running 200 mhz computers.

You’re way behind the curve anyway… any kid smart enough to know about VNC (it’s been around before you knew what it was) is already using it and us people ahead of you guys already blocked it.

Another whiney “high school” victim of being in high school *rollseyes*… ahh.. teenage angst.

82. DarthBalls - May 19, 2006

Any school of some decent size with have an IT admin who will control the firewall and settings on PC’s effectively to prevent much of what was discussed. Yes there might be a few workarounds but as one poster stated, it will still get you suspended etc.

You are at school to learn and use the computers to aid in this, not surf porn, stream a/v, listen to music from home with shoutcast etc. When you are talking about a school and protection of all computers networked, admins will take every precaution to ensure their protection.

Nice tutorial though.

Geeks R Sexy: Here’s a short tuorial on port forwarding I already had, if you were actually inquring vs stating, http://forum.ryanmetcalf.net/viewtopic.php?t=83

Warren: Another way to execute blocked files through Novell would to be to shutdown the novell background client be either using the program “What’s running?” (assuming tasklist is blocked) or executing a .bat “taskkill /f /im n*” I had to use the bat for a couple weeks when my district blocked firefox……enough people gave them crap for that it didn’t last long.

85. LP - May 19, 2006

Good post and helpful (mostly) comments.

The few elitist IT people who are pulling out the “kids today” routine are ridiculous. I’d like to know how many thousands of dollars in software they’ve pirated over their tenures and how many systems and sites they’ve hacked themselves. Not to mention the “pron” these guys spent hours downloading from their ancient bulletin boards. And finding a way around computer restrictions is hardly bringing a gun to school. Experimenting and taking reasonable risks are part of an education. The punishment that your schools threaten you with mean nothing in the long run. I say be arrogant and look up myspace at school and try things out. You’ll learn things you won’t any other way, like being unique and creative, and most likely end up with a great career – something more than IT support for a high school.

PS – I’m sure you know this already but for those who don’t Boing Boing’s got a comprehensive guide to defeating censorware:

86. Joshua Gigg - May 19, 2006

Its a good blog, and I’ll say that I am a student.

How long is the average school day? 6-7 hours? You can’t wait less then 6 hours to get home and use your own PC, in the comfort of your own home, with no IT techs logging what you are doing.

A remote desktop connection (vnc etc.) can be a good idea, running over an SSL tunnel. However, say you use a the viewer for it, and putty to setup the tunnel. These are going to be logged somewhere on the network (the process’s that you have run), and if anything is suspicious, it will be looked into.

My school is quite lenient in terms of processes, we can run stuff of pendrives, so I have my portable firefox and a copy of putty. Now this is the odd bit – My school seems to have blocked 2082 etc. (all the cPanel ports), so I can’t do any of that sort of server control from school, but port 22 remains as wide open as the atlantic.

Also, a hint for Techs: If you disable windows explorer getting to certain directories, such as the c:\ drive etc., beware of firefox 😀 – Using Firefox, you can get into the c:\ drive, browser directories, and download files. I’ve personally done this onto one of the school’s servers, and during a boring lunchtime browsing the web, I went into it, and managed to find the school’s licence and registration key/password’s for Ranger Remote Control in a file called “README FIRST.txt” – I love single layers of security 😀

87. Mateo - May 19, 2006

in regard to 33. if booting is disabled and there is a BIOS password, unplug the machine, open it up, take out the litle round battery and leave it out for a bit. Then all BIOS passwords are reset. Dont know if this works with newer machines but some older ones it did.

94. Johnny B Badde - May 19, 2006

I’ve read many of the responses here from both the kids and the techs/admins, and I thought I would chime in (FYI, I’m 39 and school is waaaay back in my mental rearview mirror).

Kids: Hate to tell ya, but the techs/admins are right. Unless you’re pursueing a career in IT, you’re there to LEARN, not to hack computers (you have plenty of time to do that at home). However, I do laud your perserverence, focus, and ingenuity in trying to circumvent barriers. Don’t passively accept whatever computing experience your school doles out. Keep it up!

Techs/Admins: Hate to tell ya, but the kids are right. Unless you’re pursueing a career in playing whack-a-mole, your only duty is to prevent the most egregious abuse of computers, not play babysitter and/or cyber-cop. However, I do laud your perseverence, focus, and ingenuity in trying to protect students and school property. Don’t passively accept whatever clever hacks the kids figure out. Keep it up!

95. Mike - May 19, 2006

Do you guys want to know something that is interesting? Lake Washington School District, the district that covers all or most of MIcrosoft has not blocked running executables off of removable drives nor have they any CGI countermeasures. They blacklist sites and some buddies of mine have been able to use ProxyFox to go anywhere they want. LWSD administrators ARE in fact, Chumps.

But if we do something that we shouldn’t be doing, then we shouldn’t be able to do it. I recently got into some trouble; but, it did make him block the program. What would fix everything would be just to make it bare minimum, all blocks.
I am a high school student, and i do resent this motion but i wanna hear them stop complaining about having to do work ‘blocking’ things that kids found out. If they’re smart enough to do somet things, make them your assistant and they’ll help you. Jeeze, quit complaining about kids these days.

Oracle – If a kid has full physical access to a machine, the machine can be compromised; there’s no preventing it. Yes, there are ways around the BIOS password if you can open the machine; you can generally remove a battery or use a jumper to clear the BIOS settings. But most schools don’t allow kids to use the computers with no supervision, so that option isn’t usually available.

Jonny – Sadly, the role of schools has changed. These days, we *do* babysit. Besides, the whack-a-mole game is kind of fun; just as the kids enjoy the challenge of trying to get around my restrictions, I enjoy the challenge of trying to stay one step ahead of them.

my school does let us use pendrives and the system admin and my group of nerds are great friends after we helped him reset several bios passwords (we set them is the great irony), and as long as we don’t screw the network up he doesn’t get us in trouble but he moniters us like a hawk so everyday we have to find a new way to do everything, but we’ve never gotten in trouble. could someone explain the cable trick a little more explicitly?
