Q: What is 1.1.1.1? Why does it work for traceoute but not ping?

Today while trying out with networks I took traceroute of 1.1.1.1 and found my gateway address. Whereas I pinged 1.1.1.1 it results with packet loss. I googled about 1.1.1.1 and can't find any relevant results. The following were my questions: What is 1.1.1.1? As per my understanding, Default ...

Can we lock that question, 4 answers referencing Cloudflare, on a question asked 3 years before Cloudflare owned the address, is ridiculous

Journeyman Geek

Lol

@Ramhound custom flag it? It does need some pruning and maybe a post notice if anything works and say I said to flag.

Bob

@BrunoFinger You probably won't run in any problems as the 1.1.1.0/24 prefix is currently assigned to APNIC for research purposes, also given that it is widely abused for local networks (especially the 1.1.1.1 address) and is thus not going to host a publicly-facing service anytime soon. But doing so is definitely bad practice. Practically you can (but shouldn't) use any unicast non-localhost IP range you want for your local network, but then if a public site/service uses the same IP, it won't be reachable from your network. — Ale Feb 20 at 20:57

lol, barely a month is probably "anytime soon"

Michael Frank

Yea, that question needs some serious renovating.

I imagine many people fail to look at the date a question/answer was posted.

Bob

@Ramhound I chucked a protect on it.

Should at least stop the low-rep answers. And hopefully higher-rep can read the Q.

@MichaelFrank technically the date shouldn't matter. Except when it does

A: What is 1.1.1.1? Why does it work for traceoute but not ping?

1.1.1.1 is used as the default address of the DHCP server on CISCO routers. However, on the public internet, 1.1.1.1 now belongs to Cloudflare DNS service. Whois record: inetnum: 1.1.1.0 - 1.1.1.255 netname: APNIC-LABS descr: APNIC and Cloudflare DNS Resolver project des...

Srsly?

Michael Frank

Probably?

Bob

Wait. DHCP servers have an IP address?

@magicandre1981,I had the last updates but I didn't see the notification toast.Can I delete the MSU file? Thank you

Bob

12:27 AM

@FMLCat when was the last time you saw cisco respecting standards? :P

FML Cat

@Bob Yes, how do you think the DHCP server communicates with the client?

(To be fair, while it operates on the IP layer it is mostly just broadcasts)

Michael Frank

@FMLCat Instant Transmission!

FML Cat

@MichaelFrank But that's TCP/**IT** not TCP/**IP**

Bob

@FMLCat magic? :P

idk what I was thinking

Q: How do I fully uninstall Pi-hole from my Ubuntu laptop?

Yes, I know I'm lame. I just installed Pi-hole in my laptop... the one I use all the time. I thought this software works as AdBlock and, without reading anything, I ran the curl command in terminal and vòi la... I can't use internet anymore. I have Ubuntu 18.04 installed. I'm trying to remove it...

Q: Why are DHCP Offer and Ack broadcasted?

Why can't the server use the destination IP address of 0.0.0.0 as is used in source IP of DHCP Discover and Request? It can use the MAC address of the client learnt from DHCP Discover and Request to direct the frame to the appropriate client machine.

dhcp

I learnt a lot from this!

(Well the answers to this mostly)

That said while the answers are interesting and informative, none of them actually answer the question

I understand modern autogyros are much more stable, so I've probably angered the autogyro people by impugning their safety. Once they finish building the autogyros they've been working on in their garages for 10 years, they'll come after me.

who was it who had an old MBP with an issue? @MichaelFrank ?

@FMLCat the thing they're erferring to that you "instinctively" do to escape a stall is supposed to be push the nose down, which the pilots of Air France never did, unless the "instinctive" means "pull up" :S

Michael Frank

@allquixotic I did

allquixotic

@MichaelFrank did you ever fix it?

that video basically explains how to fix it, you could probably find a shop to, but more than likely it's that hardware issue

Michael Frank

I dd'd the HDD, but didn't get any further than that with trying to recover the filesystem.

I still have a 320gb image of the drive I keep meaning to investigate though... :|

allquixotic

is it a 2012 model with a GeForce GT650M?

Michael Frank

I'll check when I get home.

I don't think it was a retina display though.

Just rebooted for Patch Tuesday. It's astounding just how fast Astaroth can do this. No more waiting several minutes to half an hour like the old days.

XKCD

HISTORIANS: We've decided to trim the past down to make things more manageable. Using BCE/CE, would you rather we lose the odd-numbered or even-numbered years?

bwDraco

So... how fast do your PCs reboot on major updates?

(heck, even my old gaming laptop would require 2-3 minutes to complete a reboot – this demon needs only about one minute or so to do the same)

Michael Frank

@bwDraco I can let you know when I get home...

My laptop will no doubt take minutes, although my desktop might be fairly quick.

bwDraco

I'd say this improvement is due to the combination of a high-performance NVMe SSD and processor. SATA SSDs are noticeably slower here.

Hard drives, even more so.

allquixotic

5:17 AM

@bwDraco like a monthly cumulative update, or a version upgrade from like 1709 to 1803?

lately, on my desktop, a typical monthly Win10 patch takes like 15-30s on the shutdown part, plus ~45s for POST and the RAID card's Option ROM, plus about 2 minutes once the OS loads before it allows me to login... all in all, not that bad, and a significant chunk of the time is actually my RAID card :P

1709 to 1803 took less than an hour, which surprised me

maybe about 45m

user226528

@allquixotic Yeah. Microsoft promised as much.

user226528

They said they're now doing some of the update process while the OS is still online and you are working with it.

user226528

I, of course, won't get updated until July.

bwDraco

You know, I used to have Paragon Backup and Recovery. Every time Windows 10 updated itself to the next build, Paragon Backup and Recovery deactivated itself. The problem is that you wouldn't know until you, for some reason, pay the app a visit.

Huh... Windows 10 includes a F.Lux-like feature!

I wonder when that was implemented...

user226528

@MichaelFrank Yes, since 1703.

user226528

It's been there for one year and one month now.

Michael Frank

1703 was like.. 315 years ago.

user226528

@MichaelFrank Ha, ha. Very funny. Just for the record, "1703" mean "Windows 10 version 1703", which is released in March 2017.

Michael Frank

Oh, I know. It was just amusing the other way. :)

user226528

8:12 AM

Of course, 1703 in Gregorian calendar means 315 years ago. In Jalali calendar, it is very much in the future.

user226528

I think we are in Jalali year 1397, so that'd be 306 years in the future.

user226528

Windows 10 supports Jalali calendar.

Michael Frank

Interesting that we're only a few years from being exactly in the middle of those two calendars.

12:26 PM

Meaow.

Also odd I've not attracted much mod or CM attention lately, given my last CM warning was for being "sexist" and I've been a lot more sexist since.

Journeyman Geek

this might be a positive development?

FML Cat

Anyway, now I've hoovered my laptop, back to Far Cry 5

@JourneymanGeek That I'm more sexist or that mods are too fed up with me to deal with it?

Journeyman Geek

yes

FML Cat

Or maybe just doing it in a less offensive way

Anyway, it appears I may be suffering from porn addiction

Journeyman Geek

TMI

FML Cat

12:28 PM

(And subsequent sensation seeking addiction)

The great porn experiment | Gary Wilson | TEDxGlasgow

►

Apparently people with this relatively modern condition get frequently misdiagnosed with all that kinda stuff... and I've been pretty much misdiagnosed with all that stuff at one point yet the treatments for it never worked

I blame too much internet/computers

Journeyman Geek

You could always step away ;p

FML Cat

Which my parents tried to steer me away from, yet ironically my shrink also thinks my abusive parents were the reason I'm so messed up in the head... possibly because of the train of misdiagnoses

@JourneymanGeek I probably will at some point, need to see my shrink again first to discuss it

Journeyman Geek

ah ok

I was thinking also the stuff you're addicted to, but computers and the internet have generally have been a mental-health-positive thing for me

FML Cat

Apparently excessive porn exposure drives dysfunctional changes in your brain structure particularly in the areas associated with addiction, mood, and motivation, that affects every other aspect of your life in similar ways to depression

i.e. can cause addictive or sensation-chasing use of other things (like computer games, drugs, motorcycles.... etc.)

There doesn't seem to be evidence that too much computer/internet usage alone is detrimental, just er... spending too much time on certain corners of the internet.

Journeyman Geek

ah yup

FML Cat

12:37 PM

There is research into phenomena like social media addiction among teenagers but I suspect that's a symptom of an underlying disorder rather than driving it (same as computer game addiction is often driven by underlying disorders in the dopaminergic reward/addiction pathway but does also sometimes exist in isolation as the cause)

Anyway, that ted talk was enlightening

bwDraco

So... one thing about server gear. The few times I've encountered rackmount servers, the build quality simply amazes me. The chassis construction, especially the front cover and branding (logos, wordmarks, etc.) are often oh-so-beautifully made.

FML Cat

Mostly because I'd never considered porn addiction (personally) before because I thought of it as something completely different... but the way it rewires your brain to mishandle non-porn-related stimuli is actually the problematic part

Journeyman Geek

@bwDraco hah. The older gear's better.

bwDraco

So I wonder: Are there consumer/gaming desktops or cases built to this same standard?

Journeyman Geek

@bwDraco workstations are often built to similar standards

and low end ones are pretty close to consumer boxen

bwDraco

12:40 PM

The closest thing I can come up with is HP's $600 OMEN X chassis, but I can't find much else in the consumer computing world.

It's like build quality has gone to crap on even premium hardware.

Journeyman Geek

well, I've tended to be fond of my enthusiast cases

bwDraco

As for laptops/tablets, only Macs and Surface devices seem to come anywhere near this standard.

FML Cat

It's odd server cases are so robust, given their relative lack of being physically manipulated once installed

Normally they get shoved in a rack and left untouched for years (unless a fault/service is required). And even then that happens less often than on consumer/desktop gear

allquixotic

@FMLCat I wonder. Do men whose wives are that pretty suffer from the same problem?

Journeyman Geek

yup

nor are they really seen much

FML Cat

12:44 PM

That said, my enthusiast desktop cases have always been pretty robust, and server cases are designed to withstand a lot of vibration I guess

bwDraco

@JourneymanGeek The Corsair 760T is honestly quite poor when viewed from this perspective, but it's among the best big enthusiast cases nonetheless.

Goddamn falling baseline.

FML Cat

@allquixotic No, unless they have 20+ wives (watch the Ted talk, it's about availability of huge numbers of novel stimuli not excessive exposure to one single person/stimulus)

Although a different ted talk does suggest having a rotation of multiple partners for an unrelated though similar issue >_>

Journeyman Geek

heh

someone must be a fan of late heinlein

FML Cat

In the same vein as "server" hard drives claim to have (marketing fad mostly) "enhanced vibration tolerance" it may be server cases are similarly designed because they're exposed to large amounts of constant vibration

I know my relatively well built laptop has had screws fall out by themselves over time due to vibration (and the fact it's been serviced a few times so the threadlock has become mostly non-functional)

bwDraco

I mean, the way rackmount servers are made and branded, it exudes a level of authority that I simply can't get from any consumer-oriented desktop.

Even the best gaming PC cases don't give this feel.

FML Cat

12:51 PM

Overclocking my laptop has reduced CPU temperatures... lmao

(Granted my overclocks usually include some substantial undervolting too, thus increasing efficiency at a given load)

bwDraco

I know the profit margins in the IT world are plenty high enough to enable vendors to spare no expense, but has the race to the bottom in consumer computing made this completely commercially unviable?

I mean, I'm sure someone appreciates build quality in desktop gear.

!!/ultraheaddesk

allquixotic

@bwDraco are you talking about the outer surfaces of the box, or the actual components inside? build quality, to me, has nothing to do with the case; it's about the physical durability, MTBF, stable temperature/input voltage ranges, etc. for components on the motherboard, CPU, HDDs, etc.

bwDraco

I'm talking about the chassis specifically.

FML Cat

@allquixotic He's on about the outer surfaces. Though the internals tend to be built quite well on servers as well

Robustness and serviceability, to make datacenter admins' jobs easier. Which I find kinda ironic, given most of the time I spent as a datacenter admin is sitting around doing nothing, I wouldn't mind doing a bit of DIY fidgeting

allquixotic

Apple makes all-aluminum chassis for their kit that feels very high quality on the outside, but the quality is skin-deep; they run their chips dangerously hot; almost every year they recall a Macbook because of some flaw about the crappy board; and their boards have next to zero protection against water or crumb damage
