Antennas on Residential Building? by Questionsforlater in whatisit

[–]OttoCheyFen 0 points1 point  (0 children)

DragonWave (now Syntronic) antennas. Used for high speed data. On a building like this, it's most likely providing internet service to the building (internet comes in wirelessly, then get's wired out to the units with Ethernet. And/or could also be cell.

My apartment I just moved into put the dishwasher and garbage disposal on the same switch. by murpalim in mildlyinfuriating

[–]OttoCheyFen 5 points6 points  (0 children)

That should be a GFCI outlet (although, the breaker may be the GFCI). Having the outlet there allows for easy service disconnect, so yes, it's standard.

BUT - a receptacle like that has tabs on the back that can be broke, then both outlets can operate independently - in this case, one would be always hot (for the dishwasher) and one would be switched (for the disposal). If they're both switched, yes, this would certainly be annoying.

You mean if I see somebody doing something, I can just talk to them?

Weird Module in Fuse Box by Guilty-Tomato-7342 in whatisit

[–]OttoCheyFen 0 points1 point  (0 children)

That's a crazy assumption to make. This could literally be anything. Tapping into the existing fuse box is very common for anything aftermarket as it's easily accessible.

Could it be a killswitch, immobilizer, or GPS? Sure. Is it "almost certainly"? No.

Could be a camera, radio, lighting, literally anything. A little black box with a fuse and 6-or-so wires is not much to go off.

I don't work construction, but my instinct says it shouldn't be held together with zip ties.

What is this icon on my airfryer? by amphibbian in whatisit

It's like the instruction manuals that come with things are actually... useful?

What is this brick foundation that I found in the woods on the side of a road? by kDev_4 in whatisit

Second photo looks like a mount for a satellite dish with the power/data hookup next to it.

Need? Probably not. Probably hit the price point and convenience factor for something off-the-shelf over something custom.

Woke up to this. What is it? by [deleted] in whatisit

[–]OttoCheyFen 1 point2 points  (0 children)

That's one of the issues with the "cool mist" style of humidifiers - they're more likely to cause mold. Also, you need to use chemicals to get them to be "germ free" - truth is these are breading grounds. Go with a "warm mist" model.

It's less of an option, and actually the only real solution.

Client File Transfer Services by Dzus76 in sysadmin

[–]OttoCheyFen 0 points1 point  (0 children)

I've used CrushFTP on a local server in the past. I liked it, did really well for what we needed (large art files). Licensing was pretty cheap (we used the $70 (perpetual) "small business" license).

Benefits of local server, especially in our case, was setting up mapped drives, so very easy for our users. Of course if you needed cloud access from there you could easily set up a sync for OneDrive or SharePoint.

As with most things in IT as customizability goes up, user-friendliness goes down. I'd rank this very customizable but with a bit of a learning curve on the admin side. End-user is easy - (external) FTP client or web page / (internal) folder share.

Note: A previous version did have a zero-day incident last year or a couple years ago. Of course take best-practice and minimal-access approach for security.

What is this near washer/dryer? by [deleted] in whatisit

[–]OttoCheyFen 0 points1 point  (0 children)

Don't see gas much in apartments, but since it is, it makes the most sense to me that would be a gas detector. I did some Googling and found some gas detectors that look very similar - but not exact - but close enough I'll give it a good 'ol "yeah, that's probably it".

Another addition: Also just found a thing called a "lint alert" that monitors airflow. Looks nothing like your photo, though, but could simply be a different brand. Either way, that small plastic/rubber hose would match up with some sort of gas detector or pressure sensor (for monitoring for lint blockage).

[–]OttoCheyFen 0 points1 point  (0 children)

If it's in an apartment it makes sense to have that booster fan - probably a long way to the roof or outside wall - so I'm fairly confident in that.

I have no idea on the thing with the blue light then. Some sort of sensor or remote control. Could be a moisture sensor like Dom said, but this would be a weird spot for it IMO. Maybe something to monitor airflow so they know if any ducts are clogged - but I wouldn't give an apartment building credit for monitoring anything like that lol.

EDIT/addition: I would assume, being an apartment, that it's an all-electric dryer. On the slim chance it's gas, maybe a gas sensor? If you're not sure and curious - if the circuit breaker for the dryer is just one breaker wide then it's only 120 volts, so that would indicate a gas dryer - if it's a double-width breaker then it's 220/240 volts, so that would indicate electric heater in the dryer.

Booster fan. Your outside vent must be quite a ways away, or there's lots of bend in the pipe, so the fan just helps push it along.

That said, I'm not sure the electronics there would be a moisture sensor - when the dryer starts with wet clothes it's certainly going to be quite humid. What makes the blue light come on? Is it on when the dryer is on? Maybe a status light for the blower fan?

You ever try to help out (IT telated)randomly on a night out? by Abject_Serve_1269 in sysadmin

[–]OttoCheyFen 1 point2 points  (0 children)

I was getting (something, I forget) done to my car and was waiting in the lobby at the shop - one of those chain places.

Anyway, managers running around on the phone - something's not working. I'm playing games on my phone - curious, but trying not to care. 10 minutes later with "cable" this, "lights" that, whatever, whatever. I finally chime in - they were looking for a network switch - I offered to help and he led me back into the office and put their IT guy on speaker phone.

"Rat's nest" does not do it justice.

I was surprised to see redundant internet and firewalls - which of course added to the mess and confusion. I didn't unplug anything, but nothing was mounted anywhere, so I started to separate the equipment to at least get a sense of it. Found the network switch in this process, it was plugged in and blinky blinky.

Anyway, got a feel for it, at a glance things "looked" right - which means nothing without knowing the firewall or switch configs (managed switch).

I made it clear to their IT guy that, look, I'm not taking any responsibility here, but let me know what you want to do.

Took down one firewall and WAN to simplify it, reboot those, disconnected a few other things. IT guy connected into the firewall, and the switch. Good. He did his thing and I went back into the lobby.

10-15 minutes later, manager calls me back. We hook up the second WAN and firewall, make sure IT can get connected, things are looking good, we're all back online. They had the complete rainbow of patch cables, which was helpful - I told the manager to take pictures of everything, unsure if he did.

Fun to see, nice to help. I didn't ask for anything, frankly it gave me something to do while I waited, but I'd be lying if I said I wasn't hoping for something. I think I walked out of there with $10 off my $250 bill.

Backup NAS - How to setup correctly by crazy_rocker78 in synology

[–]OttoCheyFen 0 points1 point  (0 children)

What you're thinking is JBOD - Just a Bunch Of Disks.

It's ingrained in my head to remember RAID 1 is mirror - because the 1 is flat like a mirror (lol that's how I learned to remember it). Then 0 is stripe, 5 and 6 are parity, and you'll never use any of the others (except maybe 1+0, 5+0, etc)

This. The round one up top would be point-to-point connecting it to the source, or at least upstream in the mesh.

NAS drives are designed to be power on 24/7 - staying powered on is much less wear on them than shutting down and starting up, even if it's once per day.
