Lanschool Teacher And Student Fix Full V
Mirthe Luria
As a veteran teacher with more than 20 years under my belt, I believe classroom management is among the greatest challenges a teacher can face. Add in managing in-person and remote students, and this could be a recipe for stress. Back in 2017, Lenovo helped solve that challenge with LanSchool, its powerful classroom management software. Today, the software continues to be an effective tool for managing the hybrid and in-person learning environments.
The Blank Screen feature is also available on LanSchool Air. Like a kill switch in a motor, this feature lets educators shift classroom attention by turning student screens blank and locking their devices.
All students need is an internet connection to use LanSchool Air, making digital learning seamless even when students are learning from home. School districts can easily deploy the app to all school-owned devices so students are ready to go immediately.
LanSchool Classic continues to be my No. 1 classroom management tool for in-person instruction. As teachers and students head back to the classroom, it is reassuring to know that if we ever return to a remote learning model, LanSchool Air is there to offer support in that learning environment as well.
LanSchool Air helps teachers connect with students within a digital space to create more meaningful online experiences, both in the classroom and remotely. It includes features to help monitor and protect student devices, enabling communication and screen sharing, and providing device management to help guide learning, promote collaboration, and maximize teaching time. Top features include screen monitoring, limit web, blank screen, messaging, and push website. With LanSchool Air, educators can help improve student engagement, teach digital citizenship, and provide an immersive learning environment.
I started back at school this week after having a week off and our I.T department did a massive overhaul of our computers, network among other things. One of my funny as Teachers went on a bit of a power trip and was showing off his new found powers via this newly installed piece of software called Lanschool. Which I will admit was impressive and annoying from a student prospective.
Lanschool v7.2. In a nut shell equivocates to VNC on steroids. It allows a teacher to view ever desktop in a class room from his Teacher Viewer client whilst permitting them to carry out some of the following features (some of these features can affect an entire class room and all of its students).
Anyways me and a fellow class mate spent most of our project management class trying find a way to disable it so the teacher couldn't do any of the above (we enjoy our free mass downloading). I will admit it was a sod and I do MEAN SOD to try and remove with your limited student access, mandatory profile and our some what limited computer knowledge. In the end we worked out how to remove it, but obviously it comes back when you log off due to the mandatory profile (still its better than nothing).
We also had a bit of a fiddle and tried to obtain the same powers our teacher was demonstrating, sure enough we managed to find a work around and that work around allowed us more than a single class room (it was so simple it was not funny, which is slightly worrying seeing as the two of us are no hackers). For the record after an hour of some cheap harmless laughs at the expense of fellow class mates we ended up reporting the issue to the school's IT department and demonstrated how we could virtually spy/shut down any class room. Oddly enough they didn't seem to interested and if there track record is anything to go by this issue wont be resolved until they get around to the next upgrade (but meh we tried to do the right thing).
I am well aware of the fact that system administrators congregate on this forum and as for posting technical detail on what I have done, like I mentioned in the above it was really simple, so simple in fact that it really isn't that technical (any idiot could do it, which could explain how we managed to fluke it). Well seeing as I am a fledgling 1st year Network student, I guess that rules me out on displaying it at a Systems Admin level. =P
Obviously there are groups for teachers/students and when a student log's in we get the server software loaded on login to the domain and the teachers get the viewer. Both groups have restrictions on not being able to install software or accessing the desktop to remove it. The teachers lan school viewer has a set channel number that loads for that class room and can not be changed unless it is re-installed hence teachers can not view other class rooms other than the one there desktop resides in.
The next objective was to install the LAN school viewer the teachers were using to see if it would work, we couldn't do this in the host operating system so we thought hey we get to use VMware so why not try booting XP while bridging the network adapter and install it seeing as we have administrator rights in the guest O.S. (it worked a charm). We both also concluded that even if the school didn't provide us with the VMware application we could always just bring along our own laptop and theoretically it should work pretty much the same way.
The most amusing thing is each class room is linked via a channel number (1 to 250 if my memory is correct) this channel can only be set in the initial install process. So seeing as we have Administrator privileges within a virtual environment we could uninstall and reset the channel number to another class room on the next install (which is more than what the teachers can do).
Prior to installing the LAN school view software I was expecting some sort of password for teachers to access clients over the network, but nope nothing. From memory I didn't see anywhere within the programs install process/or the program itself that allows you to set a password. Now I could be wrong about this seeing as I did only have a fiddle for a short time (85% sure though) but I will take a good look tomorrow and confirm it.
It seems rather odd that the only security is your limited desktop access and the fact that only teachers get the LAN school viewer at login. As I mentioned in the above I am simply gob smacked at how easy it all was and if I was a malicious user god help all the students at my crappy tafe.
My school uses essentially the same thing. It's called Vision6. They're still in the process of installing it on all computers and are having trouble for some reason, therefor the computer I use is safe for now. As Sparda said, the easiest way to go about stopping the snooping teachers would be to close the port it uses, which was my initial thought (after "Fuck..."). But I was also thinking about maybe trying to disconnect his computer from *all* of the computers in my class because seeing only one computer during only one class stop responding would seem pretty fishy, especially since I'm already known as "the computer dude." I'm not quite sure how I'll go about doing this but I got a hold of the same installation they're using at my school (i found my teacher's flash drive one day with the file on it) so I plan on setting up my own little test lab to see all the possible ways to get around this. I figure it's being implemented in other classes and probably in the library as well so I'll probably have some fun messing with the other students (if I can find a way to connect to them). The installation can install both the 'Master' and the 'client' so I figure i can install the Master on the school computer to see what I can do. I've installed Master on my computer already and it prompts for a password during installation so I'm thinking the password is only to use the Master on that computer (leaving another Master to connect to the classroom password free) but I'll need to run some tests. I'll keep you guys posted if you want...
I though so to, the only thing I neglected to post was the link to download the LAN School software and the crack, reason being I neglected to send myself the link for the rapid share download during class (I was having a hard enough time hiding what I was doing from my teacher) and posting warez on here would surely equivalent to a breach of policy /instant flame.
But yeah if you only wanted to disable the app so teachers cant hijack your desktop Sparda's suggestion was far better than my own. If you wanted to be an annoying twat (not that I encourage it) all ya need is to know how to use VMware which is a piece of piss and doesn't require a guide IMHO.
We have a computer in the library with a specific purpose for changing your student login password. Its basically a Web browser only minus the Bar at the top for entering url's, back forward buttons etc. The same class mate who helped with the above and myself discovered that you could change any students password who previously changed there's. All you had to do was use a short cut for the back button on a web browser (alt and back arrow). Once that was done you had the students user ID, special word and a blank screen to input your new password. Granted they are only crappy limited user accounts but we could use that to access that student's email. The class mate I was working with in the above and I were discussing that we could create a batch file, to ping its loop back address to buy us time to leave a comp with the stolen student login, then get it to run a a crap load of net send commands (yes the admins didn't even disable that). In the end I talked my mate out of it because it is rather skiddy and whats the point of being an asshole who ruins someones day. We knew we could do it that was enough.
My teacher has this software at my college ccna/win2k3 server class, but he never uses it. it's more like his playtoy to either mess with or help others without getting up. It is a pretty cool ass program though (think about it. If you could get the software to run out side of the domain, you could have all your friends computers in view at all times *discarding weirdness and stalkery* so if they mess it up, it's all there in one interface...
