Why 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.
When you pay a lot, the support is a lot better…
I’ve worked for both individual owners and corporate owners, and it really really depends on the franchise. Chick-Fil-A is like owning a money printer as an individual owner. Pizza Hut is nearly impossible for even a large company to run profitably.
My last job was with the largest operator of both Pizza Hut and Wendy’s in the US, they filed for bankruptcy two months after I quit because Pizza Hut was such a loss that even the Wendy’s profits could not cover the losses.
I currently work with a bunch of CFA operators and no one owns more than two stores and they all seem to do quite well for themselves while paying their employees pretty damn good wages.
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)
ATA was rolled into the SCSI subsystem, so both sata and pata are covered by SDX.
BSD is, FreeBSD and OpenBSD (and every other open-source descendant) are not unix-certified, so they are not. BSD was discontinued in 1995 so I assumed that was not what the meme is referencing.
“Very weird to the UNIX world”??? It’s the only one that’s actually UNIX.
The only complaints on this entire post are down to people that have no idea what they’re doing. It’s full-on Dunning-Krueger. There are plenty of training wheels, but they are trivial to disable/bypass if needed. People need to get a lot more comfortable with justifying their preferences with “I don’t like it” rather than inventing problems and proving their own ignorance.
NextDNS is also a DNS server. It is a much more robust service but it is not self-hosted.
I use it because it’s insanely easy to use and isn’t limited to my own network. For internal DNS I use PowerDNS with NextDNS upstream. Since I have 6 users and 4 servers (3 of which are VM hosts) I pay for it, but most home users would never need to.
Check it out, NextDNS.io
If I had a store that sold everything in the world two blocks away, I wouldn’t need Amazon, that’s an excellent point. Unfortunately, in the real world, there’s just a 7-11 with a big yellow box in front.
