*Vanity* Can I really bring down the entire network if I plug in a LAN switch? *Vanity*

Hey caught this thread... but your administrator is right. You can absolutely bring down a network. There are several reasons, but I’ll give you the big one.

Your network is running something called Spanning Tree Protocol. In a nutshell, this prevents routing loops at the Switch layer. If you introduce a new switch into the network, STP has to recalculate the “flow” of your network so there are no loops at the switch layer. During the time it takes for your network to converge (figure out the most efficient way to route your information), which can be up to 30 seconds depending on what version of STP you’re running, your network is down. There are new versions of STP which take seconds to converge, but of course this depends on the equipment.

You violently jam the power-cord into the RJ-45 jack, but it won't plug in.

You turn and walk away in frustration. Suddenly you hear a sound almost but not quite entirely unlike anything earthly and you turn to see...

Ironically, you have made a point that has more impact than you can ever know.

I could go into the technicalities of it with you, but it would get long and boring.

Essentially, it boils down to hackers, viruses, cyberattacks and the like.

And, it isn't the device itself, it's what that device does. Network types all over the world operating secure networks have to deal with the consequences of someone doing exactly what you want to do. And, those consequences can cost corporations billions in lost productivity and/or lost or corrupted data. Increasingly, corporations are making this a terminable offense, that's how serious it is.

I can tell that you don't take it very seriously, but you need to. The kinds of things you are working on could as easily be affected as anyone else in your company.

That is so odd..

Yes... ;-)

Stole it from my son who is, umm, odd... (But no more so than I was at his age... ;-)

Back in the day maybe we could have gotten an IT text adventure out of Infocom - add all the stuff from Zork and H2G2 (except that Douglas Adams estate won't let you license his stuff anymore I hear..)

Speaking of which, someone just tried to connect the controls for flood control dam number 3 to the network...

And on that note... catch you later.. ;-)

(Must arise and earn some Zorkmids in the morn ;-)

I’ll put in a ticket (Evil user laugh), then call my boss’s boss!

Get that ticket in, then call immediately! 30 seconds certainly should be enough time for IT to address any issue that you have. Especially if it's after hours! And, after you call and make the biggest stink possible, go home, or make yourself unreachable in some way. IT guys certainly don't need your assistance in addressing your issue. They're all clairvoyant.

And, make sure that your boss's boss *can't* fix the problem, as well. That's the most sensible alternative, if you're a user.

(That's a major IT complaint. Users need something fixed. So, do they call me, who can actually FIX the problem? No. Or, do they call my boss, who either can fix it, or who can walk to my desk and ask me? No.

Nope, users call the CEO of the company. Which makes perfect sense, because he knows NOTHING about computers other than how to check his email and watch DVDs, and because he's at least 3 or 4 levels removed from someone who actually CAN address the issue....)

I wonder how a text-based IT Adventure game would do....

Actually that might be pretty cool if it was done by text message. You text your next move to the server and it sends the response back to your phone. Please cut me in on the profits.

That’s because s*** rolls downhill, and in order to do that, one must start at the top!

(I’m on much better terms with my guy than that. I’ll give him a ring later this morning. Oh, figured out why #34 was pulled. AM didn’t like me threatening you. Hope you didn’t mind much, it was completely in jest.)

I didn't realize that you HAD threatened me.

I feel so.....victimized. Will see if there's a government program for that.

Installing a router on the network WILL bring the whole thing down if the router is giving DHCP IP leases. I mean, instant down with a difficult restoration.

LOL...yeah, that'd do it alright. Ouch.
