It’s a per-network setting that can be toggled off for your own private network if you want to.

mark3748@sh.itjust.worksto Selfhosted@lemmy.world•How can I keep my forwarded port secure?English245·10 months agoWhy is port 22 open? Is this on your router as well or just the server?
This is SSH, which you should pretty much never have open (to the internet! Local is fine) MC is by default 25565. You will have every bot on the internet probing that port.
You’re saying that data centers are replacing batteries constantly…just imagine the labor costs on that (and the down time), not even considering the material cost.
I’m the tech doing the battery replacements. The big boy UPSes are typically a 3-5 year replacement cycle. Something like this:
(I just picked the last one on my phone so not a great picture, they’re about the size of a small refrigerator)
On rack mount and desktop style UPSes 18-36 months isn’t unreasonable. Some of the smaller UPSes, like APC 750s, go through batteries even faster. My personal theory is that they just get and stay too hot.
There is typically zero downtime while servicing any of them, every critical system has redundant power supply and battery replacements usually don’t interrupt power output anyway. It would take multiple failures to cause any sort of significant downtime, and if it would, we just do them during scheduled downtime.

mark3748@sh.itjust.worksto Android@lemdro.id•Big oof: The Google Pixel Watch 3 can't be repaired, only replacedEnglish161·11 months agoI’ve worn my Series 4 every day since September 21, 2018. My son is still using the Series 3 I gifted him the same day. I bought that one September 22, 2017. I don’t baby my watch in any way
Thought about an upgrade a few times, but haven’t had a compelling reason to do so
mark3748@sh.itjust.worksto Asklemmy@lemmy.ml•What is something people you encounter at your job say that makes you want to scream? (Job, person & quote)2·1 year agoI’ve had exactly two dishwashers completely stop functioning in my entire life. Both were GE post Haier and within the last 6 years. Also had a Haier made GE microwave completely fail.
I replaced the microwave (and the matching stove) with Samsung and haven’t had one bit of trouble with either.
I thought I had just gotten a lemon, but three separate failures within a couple of years has really soured my opinion of them. I was a lot more worried about the Samsung appliances I bought, but they’ve been a dream.
Note: I am not recommending Samsung appliances, at all. I got an amazing deal and fully expected them to fail shortly after the warranty was up. I’ve had to repair several of my friends and family’s washers, dryers, and refrigerators. Samsung’s poor reputation is well earned, I just got lucky

mark3748@sh.itjust.worksto cybersecurity@infosec.pub•Has ethernet become illegitimate? A librarian flipped out after spotting me using ethernetEnglish47·1 year agoAnother library in the area has ethernet ports but they are just decoys (dead ports). I asked the librarian what the problem is, why they are disabled, and whether we can turn them on.
They’re not decoys, they’re just not patched. Because we don’t generally patch anything that’s not going to be in use. Also because some rando will probably attempt to plug their nasty ass laptop into it, which is also why we block port intrusions.
mark3748@sh.itjust.worksto Asklemmy@lemmy.ml•How do I wipe a modern SSD to prevent data recovery?21·1 year agoIt is the only approved method for data destruction for the several banks and government agencies I support. If they trust it, I trust it.
I have checked a couple of times out of curiosity, after a secure erase the drive is as clean as if it had been DBANed. Sometimes things are standards because they work properly.
They’ll have to get a new SAS controller unless the RAID controller has an HBA mode. Running ZFS under a RAID controller is the best way to lose all of your data.
ZFS is wonderful but it takes quite a bit of planning and specialized knowledge to implement properly. Your fear of a failed RAID controller is a bit much, too. I’ve had to deal with a single controller failure in 30 years of IT (and I’ve done warranty work for all of the major OEMs in corporate IT for most of those 30 years)

Chasing hardware issues by playing with software only wastes time, so ruling out the hardware first is a good idea
mark3748@sh.itjust.worksto techsupport@lemmy.world•Something is seriously wrong with my desktop.2·2 years agoI would probably test both, just to be sure, but I wouldn’t bother with the long test on anything but the system drive unless you suspect a problem with it. The quick test is usually sufficient at catching most issues.
Since you’re looking at data corruption that persists between installs, your boot drive and memory are the most likely culprits. If the test says the drive is fine, then memory tests are next.
mark3748@sh.itjust.worksto techsupport@lemmy.world•Something is seriously wrong with my desktop.142·2 years agoLooks like failing storage. You may be able to initiate a SMART self-test from the BIOS, or you can use the manufacturers tools. Seatools works on non-seagate drives and has a live USB option.
Do the short test first, if it passes, do the long one to confirm. Short test takes about 15 minutes usually, the long one can take a couple of hours.
mark3748@sh.itjust.worksto Privacy Guides@lemmy.one•What do you use for cloud storage and why?English12·2 years agoWeirdly enough, I didn’t say it was my only way to store anything, nor that the program stores photos at all.
It syncs the photos from my devices, the storage for those photos is on a separate server (as is the NextCloud storage) that is encrypted and backed up to Backblaze B2.
Immich is a gallery and organization app that syncs from your devices, the underlying storage is whatever you provide.
I agree that the gatekeeping isn’t a good thing, but you should learn at least the basics of the CLI. It will give you a better understanding of what’s going on behind your GUI and makes troubleshooting and fixing problems a lot easier.
Definitely not required but it is absolutely a skill worth having.
