I can either check which policies have gotten corrupted or how the IP configuration is broken or which of a thousand different files is a trojan, or I can just wipe it all and go back to something I know works and isn't corrupt. Gpupdate is an essential tool in a managed environment. Rebooting really does cure a multitude of ills. Flatten and re-image is the only way to go in a very large environment, or anywhere there's a shortage of engineering talent to really dig into the cause of the one weird issue on one laptop. Root cause investigations on one-off issues are luxuries that you pay for with the time of your most skilled desktop engineers. You want them spending their time making sure the image is stable, not fixing isolated issues. The key issue is, is a re-image faster than spending a lot of time researching an issue ? Your priority should be getting the user back to work as fast as possible. Slow day ? Interesting problem ? Already got the user back to work somehow ? Go for it, dig deep. But any issue that survives a re-image to a known good state either has some weird interaction of non-standard apps, or is a hardware issue. And if it looks like hardware, swap drives to a good system to rule out software.

The first time a weird issue happens that I can't fix in 15 minutes, I have the PC reimaged. It's just not worth the time delving deep into event logs, procmon, and similar poo poo to find out why it happened simply to satisfy my curiosity. If the same issue shows up a few times then that's justification for spending a half day on trying to find out which arcane configuration item exactly causes it, if only to save time on future incidents because I can forward the solution to 2nd level.

You both are missing the point. It's not that those aren't useful or that they don't solve problems. It's that for some people that is the ONLY way they know to solve problems. They have absolutely no understanding other than a rote recitation of commands or mouse clicks. And when the time comes where those tools are the wrong thing for a particular problem, these people are ineffectual at best or actively exacerbating the issue at worst.

flosofl posted:You both are missing the point. Well that's certainly true. We had an outbreak of "reset it to factory default" in our desk side group a while back. Factory default on Elitebooks is UEFI boot, and we use Legacy. A reset makes it unbeatable, and also triggers Bitlocker. Every one of those tickets had to go to the hardware group who knew the correct BIOS settings and could retrieve Bitlocker keys. They did a printer too, goodbye name and DNS entry ! Also, the third desk side visit to that printer ended up with the transfer roller removed. Why yes ! It is printing very faintly !

Ever get a case/ticket that you know is the leading edge of a very massive shitstorm, but the case creator just doesn't know it yet? I got a support case escalated to me, followed by a very nervous phone call by <customer> VP of Operations saying basically the same thing: "Hey Agrikk, we are running low on IP addresses in our Production VPC. Can you please increase the number of available IP addresses?" So I take a look at the VPC in question and it has a /20 mask specified. and almost all of the four thousand IP addresses are in use. Welp! Edit: For those who might not know, it is currently impossible to resize a CIDR block on an existing VPC. Choosing the right-sized CIDR is literally The One Thing You'd Better Not gently caress Up when examining your VPC design for just this very reason. AWS has a helpful doc on the subject: quote:You can't change the size of a VPC after you create it. If your VPC is too small to meet your needs, create a new, larger VPC, and then migrate your instances to the new VPC. To do this, create AMIs from your running instances, and then launch replacement instances in your new, larger VPC. You can then terminate your old instances, and delete your smaller VPC. For more information, see Deleting Your VPC. That's it, just snapshot all of the production instances of a $XX billion company and flip them over to a new VPC! What could possibly go wrong with migrating and re-IP-ing several thousand EC2 instances, RDS databases and service endpoints? Yeah, this is going to be a fun conversation to have. But at least I know what I get to work on for the next few months. Agrikk fucked around with this message at 20:14 on Apr 20, 2017 |

I would say this does not only apply to your instance, but just in general, it's a pain in the rear end to deal with something like this when you could have just planned bigger from the start. You current needs are a /26, so you think a /24 is good enough? gently caress it, make it a /16 or whatever.

Previous job had a bunch of small satellite sites with like their own /30 carved out, almost all sequentially, so you'd have to re-ip everything to a different subnet instead of just expanding it. Guess what happened when they went from analog to voip?

I'm ornery today, and the users aren't improving my mood.Special Needs User posted:Subject: Printer connection down Next on the hit parade, a user who had to be told twice that access to an application wasn't handled by my Service Desk, but by filling out a form that was then automatically sent to a security review team for that application, since it deals with a lot of PII. Then they forgot their password to a different application, I reset their password with a flag to expire it on next log-in. It took 3 emails to direct her on how to change her password after that when the screens are: 1. Standard log in screen 2. Screen saying password is expired and must be changed, with big "Click here to change password" link. 3. Screen with fields for current password, new password, repeat new password, submit. That's it. That's all that's on all 3 of those screens. Then we got a user who emailed wondering what the criteria to use on-site printers, and when to use the 3rd party printing service we have are. That's not so bad, except for directing it to Facilities instead of any IT department. Head of Service Desk answered her "There are no criteria, use your judgment." About 20 minutes later we get another email asking what the criteria are. As a reply to my boss's email. People are extra stupid today. ETA: so, the second user managed to lock herself out of her computer account. It was reset, and then she managed to fail to set a new password on that.

jre posted:Why would you migrate them rather than just use cloudformation to bring up new machines in the new vpc ? If you have several thousand pets you're doing the cloud thing wrong Who said anything about pets? It has nothing to do with the servers themselves. Those get shot in the head over the course of several days. but setting up routing into and out of the VPC from your global operations and your network of partners and vendors is non-trivial. Also migrating terabytes and petabytes of data from RDS instances into your new VPCs RDS instances. Also vetting and testing your new infrastructure, etc. Yes, I built my data center in five minutes. But moving existing data there, hooking up connections and testing all the interoperability will take weeks at the minimum.

I've seen places assign /16's to every network, and eventually you're taking up a good chunk of RFC 1918 addresses and connecting to another company's network probably involves bidirectional NAT or something.

Dr. Arbitrary posted:Aren't most phones on ipv6? Depends on carrier and how old the phone is. For instance on Verizon Wireless these days, you will still get IPv4 only service in some areas because the local equipment was not actually able to handle IPv6 routing at all, or had such problems that it's temporarily disabled. Most other carriers have some level of problem like that from place to place. And then of course you have things like some older phones not supporting IPv6 at all, or only supporting them with updates the users haven't applied, though that's becoming rarer each day.

One day I was sitting at my desk in my home office, and I noticed the can was full. So I threw it out. Later that day my wife asked me where all the trash went, and I said "I threw it out." Turns out she had put all the receipts for her recent clothing purchases in my desk trash and needed to return something. She was a little angry about it, and my laughter didn't help any. So while I can't claim I've ever done the deleted items folder comparison to trash can thing, I can unequivocally say that my wife would be able to say "yes" when I asked if she felt the trash can was the appropriate place for something she might need later.
