A significant number of people I know seem to have their medical training from facebook, so that's hardly surprising.

When I worked for the state government, they managed to block most chat apps of the time, including their web-based options (1999-2002, for context, and none of us had mobile phones). I had two friends in another building, so weíd use email like IMs. I guess the Exchange admin didnít notice or didnít care that three people were blasting several hundred emails a day at each other with maybe a sentence or two apiece in the body.

I've done that. I also spent much of 2003/2004 using net send to throw messages back and forwards around the labs in college because people refused to use IRC. Messages like "Hey 192.168.0.7 are you Bob or near Bob? If not Bob tell Bob to reply to 192.168.0.69" all day every day, until the network administrators ended up disabling it. Not sure if it was due to sheer volume of stupid traffic, disrupting lab exams, or that one dude who liked to "anonymously" send misogynist abuse to whoever he noticed.

I did this as well, but in middle/high school and it was the Novell Netware equivalent on Windows 3.1/NT3.5 in the mid/late 90s. Much fun was had until some dumbass sent a nasty message to a teacher. I remember seeing a group of people standing around one of the library computers figuring out how the function worked. They eventually disabled it.

All the teachers did allow us to openly play NetWars though, so that was a plus. Some of the computer lab teachers even held NetWars tournaments.

It was a bad idea in hindsight, but we used to play Doom on the shipboard network when I was in the Navy.

It ended up being pretty good for communication, because it had chat that people were always paying attention to.

I answered, with the full might of over 10 years of experience in the field: "Have you tried turning it off, and then on again?"

They user did as instructed, and the issue was solved.


And that, my friends, is why they pay me the big bucks.

They really don't

I've been cursed with doing phone support for about six more months until we spin up some type of tier 0 helpdesk. I've been getting better at not insinuating the problems are all caused by the user. When I need them to turn stuff off and on, but they're not the cooperative type, I'll usually go:

My favorite one was a guy who worked for the ISP asking me to unplug both ends of the cable, flip it around, and plug it back in. (The actual problem turned out to be, inexplicably, "modem refuses to connect at speeds greater than a 56k connection if its power is coming through a surge protector of any kind")

When I first worked at First Job™, all of our desktops had public IPs. Net send got disabled after a spammer found our IP range and hit the entire Class C block.

NAT also became a thing shortly thereafter.

Take care with that! We have not fully ascertained its function, and the ticking is accelerating.


I just bought a supermicro motherboard off of eBay. Itís IPMI port had a public IP address configured.

Of course its credentials were the default ADMIN / ADMIN.

I hope it was firewalled somehow, but I like to think that the reason I got the Xeon / mobo / ram combo for such a steal is that they couldnít figure out why it was mysteriously shutting down and/or rebooting all the time, and decided it was faulty somehow.

You just reminded me that when I went back to university in 2015 the campus wifi network for the "school of computing" for some reason gave every device a public IPv4 address, but allocation was limited so only the first however many people to connect in a day got one. Get in too late and good luck getting wifi for the day! I have literally no idea WTF they were thinking there, and happily there were plenty of other schools AND a university-wide network you could use instead.

This has been wracking my brain for a bit. Given how surge protectors work they're not altering the voltage out of its sine wave like a crap UPS can be built to do. I'm assuming this is a home modem that isn't gonna pull 20A either.

So I searched for the drat answer like a good computer janitor

quote:

Power bars usually contain Metal Oxide Varistors to protect the connected equipment from any over-voltage spikes.  They can operate without any problems for years, but, when they start to fail they can emit a large amount of RF noise into the RG-6 cable and power cable.  This can cause problems as the noise can overpower the cable signal.  Its not a typical failure, but when it does happen it can be difficult to detect..
Yeah that would absolutely mess up a cable modems ability to tune. Of course the thing that smooths with the signal then does the opposite when it breaks, duh.

Now why none of them worked at all is pretty weird. All bought at the same time?

One bad bath would do it.

And if you like that kind of signal interference, USB 3 ports emit noise on channels Bluetooth uses. The strength and frequency of the noise varies so it can be really hard to isolate this as a cause. In 6 years on a campus of 12-15000 people I'lve seen this twice.

It's kind of a lovely request, but it does actually check a lot of good steps. It reseats both ends of the cable, ensures that it's the same cable on both ends and not cut or damaged.

Of course, the main reason for doing it is to check that one end of the cable isn't lying on the floor, despite the user swearing on their mother's life that they checked it was plugged in.

Nope. Just a simple camera module.

It was a real puzzler. It seems that the internal circuit produces some kind of RF intereference - enough to stop a Garmin working, but only when right next to it.

E: it wasn't even a signal from the power cable or the battery charging circuit.

It can happen with an improperly insulated circuit, and those electronics are such low power the interference wouldn't transmit far.

Generally when the OS loads its HAL, it evicts all the I/O code the BIOS supplied and begins using its own drivers entirely. That's why if you try to install an old Windows NT on a system with USB keyboard you will lose the keyboard ability soon after it begins loading its drivers. Unless you supply a USB driver for it too.

thats dumb, tho I can see it making sense on older OS/hardware setups.
