12:00 AM
I could possibly throw on a iscsi target on my home box
Not enough space tho
 
Bob
btw, @allquixotic, I figured out how to get the newer supermicro firmware to work properly with uefi boot
it's really fiddly
basically efibootmgr doesn't work
 
@Bob Really weird is my middle name
I wonder if using a mobile hotspot device instead of my mobile phone would work better as a mobile hotspot device
 
Bob
@allquixotic have to remove the efibootmgr entry, install a proper shellx64.efi 2.0+, boot into that, use bcfg to add the entry, reboot into firmware, and within the hard drive suboption select the new entry
 
Mainly as in the positioning and orientation of the antenna may be better optimised for fixed/desktop use instead of handheld
Getting a bit tired of having 80-200Mbps speeds while holding my phone dropping to 10Mbps as soon as I put it down
Lol so they're putting fake, nonfunctional metallic contacts into opto-mechanical keyboards now, to emulate the "clicky" sound of an actual mechanical keyboard
 
12:35 AM
Razer was doing that, weren't they?
 
12:52 AM
Razer have optical keyboards?
> Transcend has announced its first SSDs based on 3D MLC NAND flash memory. The MTE850-series drives are aimed at the higher-end of the market and promise up to 2.5 GB/s sequential read speed along with endurance-related advantages of 3D NAND.

Transcend does not disclose exact specifications of all its new MTE850 series SSDs, but only shows their pictures as well as performance numbers for the flagship 512 GB model.
Oh come on will somebody release something to compete with Samsung's 2TB NVMe SSDs already
Crapdragon X10: Category 9
Crapdragon X12: Category 12/13
Crapdragon X16: Category 16/13
Crapdragon X20: Category 18/13
Consistent and predictable naming ftw
I guess they couldn't inflate their capability nnumbers anymore so just inflate the marketing instead
What's next, X24 modem with Cat 13-19.5 capability?
It's like 3.5G phones being called 4G, 3.9G phones being called 4.5G/4G+, and 4G phones being called 5G all over again...
In fact it's the same market so I guess that's the new normal now
Add moar G's
Real world capability still hasn't even improved over the X10
 
@Bob @allquixotic minor HVing here but how do you guys backup your servers?
 
Bob
@JourneymanGeek uh. You did see my question last night right? :P
 
Bob
@JourneymanGeek the one asking about cloud storage?
 
ah!
Oh, I mean the system not the data
Too much odd stuff to do it otherwise
 
Bob
1:02 AM
@JourneymanGeek Ah, the system ... isn't backed up :P
 
Bob
I have a ridiculously well documented install process now, in the event of loss :P
 
I figure I could do a cp backup
alas. the dedi grew organically
 
Bob
And it actually sits on a ZFS mirror (zraid1 on the other server)
and I take ZFS snapshots before upgrades
 
I want to upgrade major versions of the OS so...
ah
 
Bob
1:03 AM
So I only need to do a rebuild in the event of a full filesystem loss
 
shutting down to image = too much downtime...
 
@JourneymanGeek I run more servers than both of them and you don't care to ask me? :-(
 
@PowershellforLinux What do YOU do? ;p
 
Bob
@JourneymanGeek Weren't you the one who suggested rsync? :P
 
@Bob system, not file level
 
Bob
1:05 AM
For the most part, Linux is pretty happy with a plain file-only backup
@JourneymanGeek I'm quite literally installing a new system right now by exploding a bunch of files into a dir
 
hm. I guess I could tarball the world.
 
Bob
That's what debootstrap does :P
 
Then again my answer as far s my personal servers go... I ... don't? 😖
 
I actually shouldn't really have anything running on the host (byt I do)
@PowershellforLinux gee. That's helpful.
 
When I do it's just snapshot and live image the VM
I only usually do that when migrating or expecting something bad to happen tho
 
1:07 AM
Well, right now I'm shutting down the VM, and tarballing it
the main machine needs an update too.
 
What VM software are you using?
 
Bob
@JourneymanGeek You don't even need to shut down
just do a live backup... :P
 
Perhaps I'm too used to enterprise software but all the VM hosts I run allow live snapshot and imaging
@JourneymanGeek What storage backend?
 
errr
qcow2
 
1:08 AM
QEMU?
 
Last I recall that should support snapshotting easily enough
 
I don't remember the reason for it.
 
Bob
@JourneymanGeek You use libvirt yea?
 
1:09 AM
Or do you specifically need file level from within the VM?
 
Ok, two problems
1) Backing up VMs
2) Backing up the dedi it runs on
1) I shut down the VM, make a copy (actually gzipped it, which was dumb - copying THEN gzipping makes more sense?)
2) I have no idea
 
I don't get why you don't just do Snapshot VM, copy/gzip/tar/7zip the snapshot, delete snapshot for 1)
 
snapshot with?
 
If you're happy with a compressed full image backup, which isn't the most efficient thing in the world but works
 
Eh, I'm happy with a compressed full image backup.
 
1:13 AM
@JourneymanGeek Well qcow2 pretty much supports it natively
 
> Making any changes to a base image (centos-cleaninstall.img in our example) will corrupt its snapshots.
which indicates I need to shut it down while backing up anyway ?
or switch the VM to run off the snapshots..
actually...
 
@JourneymanGeek No
It's qcow
The base file remains an immutable clone of the VM at the time the snapshot was taken
 
Changes get written to a new file, which becomes the "delta" since the last snapshot
 
1:17 AM
It can become a bit space inefficient though, if you don't compact/coalesce them once in a while (I dunno how qemu handles deleting snapshots tbh)
 
@allquixotic I read through that and it dosen't tell me anything ;p
OH
 
@Bob what was that web based KVM front end you were talking about?
 
1:19 AM
Beep, beep - I'm a sheep
 
@PowershellforLinux I'll look up the equivilents for KVM :)
 
> Live Snapshots

Overall concept
The idea is to be able to issue a command to QEMU via the monitor or QMP, which causes QEMU to create a new snapshot image with the original image as the backing file, mounted read-only. This will allow the original image file to be backed up.
 
Bob
@JourneymanGeek uh.
 
kimchi or something?
 
Bob
1:20 AM
 
@JourneymanGeek Uh
 
Bob
@allquixotic I dunno if you saw above (supermicro/ovh thing)
also, s/eep/aaa/
 
@Bob What?
Beep beep I'm a shaaa?
 
Bob
lol
 
I'm a power user and I do none of those things
IMO how much of a power user someone is on a mobile device should be defined not by how much CPU, apps, data, or battery they use, but by how long it takes before the oleophobic coating is worn off their display.
 
1:22 AM
I only do #2 and #3
 
Well if you s/power/heavy
I use spotify a lot now but most of it is pre-downloaded not streamed
But err... yeah. Coating on my phone rarely lasts more than 4-5 months from purchase.
 
I make Verizon bleed for offering limited-unlimited data and hog tons of data watching youtube on my iphone's nUDP
 
@allquixotic -_-
 
Bob
@allquixotic can't remember if you did a firmware update or switched back to legacy boot or what
 
I'd normally say it's people like you that drive operators to withdraw unlimited services but right now I'm making 3 bleed for offering limited-unlimited data and sucking up hundreds of gigabytes per day
 
Bob
1:25 AM
@allquixotic streaming music/video doesn't sound like a exclusively power-user-ish thing to do...
maybe a power-hungry-user
 
@Bob Tjat's probably what they mean anyway, given their image is of a power usage comparison
 
@Bob it's UEFI iirc
 
When I think power user I think root, system mods, advanced functionality, customization, low level tools ,etc.
@Bob Wait, did you buy a new new server or is this the OVH Australia one you ordered something like 8 months ago?
 
I never updated the firmware on my current box, and last I checked it was updated to the latest
what gen is yours? mine is an E5-v2
 
Bob
@allquixotic is it still in that state where you have to boot override on boot?
@allquixotic X11SSE-F 1.0b
 
1:28 AM
@Bob no; I got rid of that a long time ago when I downgraded from the 2 x E5-v3 (too expensive) to the year with a huge discount of the SP-128-S (1 x E5-v2)
 
Bob
The brand new AU "Discover" servers
@PowershellforLinux same
@PowershellforLinux AU, was delivered about a month ago an I finally got around to setting it up
@allquixotic Oh. Might be a bug in the newer firmware then.
 
it's a C600 based chipset apparently
 
Bob
Basically efibootmgr doesn't write the right things, so you have to get a custom EFI shell and set things up via bcfg
 
@Bob Eww, stuff like this is why I hate EFI booting
(Similar problems wiht my Windows laptop lately)
 
@Bob mine is the X9SRE, two generations older
 
Bob
1:30 AM
@PowershellforLinux Except I can't even get grub to see my ZFS root, soooo. yea.
@allquixotic Yea, probably the same as my working CA one if you've got an -S
But your previous newer one had a similar bug, yea?
 
at one point or another
 
@Bob My EFI would only see the boot manager on my non-boot drive, which Windows refused to add my real boot drive's boot thing to the bcd of

but I'm 110% positive that the USB is just a recovery Debian install and is not the boot device in any capacity
no ESP but partition table is GPT format
 
I have 2 x 2 TB HDD in software RAID, so I guess the actual bootloader is GRUB Stage 1 in the first logical blocks of the disk, then it loads the rest from sda2
 
1:34 AM
Don't you need an ESP to boot EFI?
 
Bob
@allquixotic So legacy boot then?
@PowershellforLinux Not if you have a single partition, which causes EFI to boot in removable media mode (which is often glitchy too)
But I think if you have a GPT you'd need an ESP yea
 
@Bob seems like it - CSM is capable of booting in BIOS mode with a GPT disk, something you refused to believe before :P
 
Bob
@allquixotic Hm... I don't recall refusing to believe that...
I do remember saying Windows won't do it.
 
Bob
As a policy decision by Microsoft, AFAIK
Not that it's technically impossible.
 
1:36 AM
that's what it was... it works fine on Linux but doesn't work on Windows, right
 
Bob
GPT intentionally has enough of a fake MBR space for bootloaders to insert themselves
 
@PowershellforLinux do it
 
> For reverse compatibility, Linux can use GPT disks in BIOS-based systems for both data storage and booting, as both GRUB 2 and Linux are GPT-aware. Such a setup is usually referred to as BIOS-GPT.[30] As GPT incorporates the protective MBR, a BIOS-based computer can boot from a GPT disk using GPT-aware boot loader stored in the protective MBR's bootstrap code area.
 
Bob
You can boot a GPT drive from an old BIOS that doesn't understand EFI at all, given a legacy bootloader in that fake MBR
... what @PowershellforLinux just quoted :P
 
@JourneymanGeek And live in a faraway town I don't want to live in just for hte money, again?
 
1:37 AM
@PowershellforLinux yes.
 
If the job wasin Melbourne I'd totally go for it
Maybe I should actually look for jobs in Melbourne
 
Bob
@PowershellforLinux job => money => move to better place => better job
 
Bob
as the old saying goes, it's easier to find a job when you already have one :P
 
Job => Money => Move to better place => ??? is where I am atm now anyway
Had job, had money, moved to a better place, now move to a worse place again for another job? confused
Sounds like a bootloop to me
 
Bob
1:39 AM
@PowershellforLinux see, the problem is somewhre along th eline you forgot to get the better job :P
 
btw, I finally got all 3 of my Dell U2417H monitors set up; they're amazing
mDP -> DP "Out" (a specific socket) daisy chained, one to the next to the next, then regular DP to DP or mDP to DP to connect to the computer, and both my work laptops pick it up in MST mode
 
Bob
\o/
 
3 x 1080p60, smooth as non-G-Sync butter can get
 
Bob
lol
 
@Bob Uhh yeah
 
Bob
1:40 AM
the ultrasharp monitors are quite nice
 
i5-4300U and i7-4700U both drive them pretty well
 
But your timeline shows move to better place before getting better job
> In case of GRUB, such a configuration requires a BIOS Boot partition for GRUB to embed its second-stage code due to absence of the post-MBR gap in GPT partitioned disks (which is taken over by the GPT's Primary Header and Primary Partition Table). Commonly 1 MiB in size, this partition's Globally Unique Identifier (GUID) in GPT scheme is 21686148-6449-6E6F-744E-656564454649 and is used by GRUB only in BIOS-GPT setups. From the GRUB's perspective, no such partition type exists in case of MBR partitioning. This partition is not required if the system is UEFI-based because no embedding of t
 
Bob
@allquixotic ^ FYI & FMI supermicro uefi boot instructions
 
i7-4800MQ*
@Bob did that before :P
 
Bob
@allquixotic Hm?
 
1:41 AM
my old server had that setup
 
Bob
This is the EFI shell/bcfg way :P
Which is apparently necessary on the new firmware
 
also I was surprised (maybe I'm just behind the times) that a 2014 Intel driver on Windows 7 64-bit on the i5-4300U box could do 3 x 1080p60 MST
 
Yay for buggy UEFI
 
I just found a link to the original audio recordings of the BBC radio show of THGTTG. So... Suppose I were to link it here. On a scale from meh to OHMAGAWD PIRACY, how would it fly? cc @JourneymanGeek / @DavidPostill
 
(Another reason I hate uEFI)
 
Bob
1:42 AM
also, adding -b makes efi shell commands use a pager
 
BIOS never had these bugs. If it existed, it booted.
 
@PowershellforLinux BIOS had a fuckton of bugs
 
Bob
@PowershellforLinux ...you were a lucky one, then
of course, with BIOS they weren't bugs
 
aside from being completely unable to ever boot off of a 4TB or larger partition
 
Bob
they were just different implementations
 
1:44 AM
@allquixotic If that's a bug then is EFI's inability to boot off 8ZiB or larger partitions a "bug" too?
 
@PowershellforLinux Give it 20 years and it will be. ;P
 
@PowershellforLinux sure, just like how Win16 can't address more than 65k RAM, Win32 can't address more than 4GB, etc... it's just that the priority of the "bug" goes from "not a single living soul cares" to "OMG THIS IS KILLING ME" as technology advances
we'll probably never (in our lifetimes, at least, with digital circuitry at least) ever reach a point where 128-bit is at all concerning in terms of its limits though
for IPv6, for the 128-bit indexes of ZFS, for a 128-bit pointer size in memory, etc... it's pretty much the end of the road, with the "limit bug" being insignificant probably almost forever
but 32-bit limits are pretty constraining in any computing resource these days
good old exponential function
16-bit didn't last long; 32-bit was venerable but easily surpassed; 64-bit is humongous and will take gargantuan efforts and incredible advances to bump against; and 128-bit is so impossibly large that it's basically the end
 
Bob
@allquixotic headless firefox bug is getting lots of patches :P
root@ubuntu:~# reboot
A dependency job for reboot.target failed. See 'journalctl -xe' for details.
@_@
so reboot depends on systemd and is broken
I can fix this!
*switches to kvm, set power reset*
 
...and my Nexus 5X has started to bootloop. I may not be able to recover it.

noooooooooooooooooooooooooooo
it booted but blank screen :(

Heh, I just realized that if Moore's Law could continue unhindered by the laws of physics, then the "useful life" of each bitness would be a constant
Whether it be 10 or 20 or 30 years, 16-bit would last as long as 32, 64, 128, 256, world without end
 
Bob
@bwDraco just LG doing LG things, eh?
 
@Bob just supermicro doing supermicro things, eh?
 
Bob
@allquixotic :P
I bet I have to nomodeset it again
@allquixotic In this case it might be Linux doing Linux things
YES
IT WORKS
 
@Bob Yeah. The same issue is known to affect the LG G4.
 
Bob
2:04 AM
*happy dance*
@bwDraco ik. I have G4.
 
I guess I'm forced to get a OnePlus 3T.
 
Bob
Got the S7 to replace it before the inevitable bootloop
 
The question at this point is "how fast can OnePlus ship a new phone?"
 
Bob
Hm. I don't have networking :(

Q: Why my ethernet interface is called enp0s10 instead of eth0?

Nico RodsevichJust that, when I run ifconfig -a I only get lo and enp0s10 interfaces, not the classical eth0 What does enp0s10 means? Why is there no eth0?

This world is new and scary.
 
...ordered a OnePlus 3T. 64GB, Soft Gold. I'll need a case for it, though.
 
Bob
2:17 AM
uh. @bwDraco I was going to say you might want to shop around a bit. Unless you've had your eye on the OP for a while.
 
This was the phone I've had on my mind for quite a while.
Feb 16 at 13:10, by bwDraco
Well, my Nexus 5X is probably coming to the end of its service life. It will very likely be replaced with a OnePlus 3T.
 
2:48 AM
@bwDraco I'm fond of my OP3. They're good phones

@Bob: Samsung's actually made fast charging with screen on worse under nougat.

4:03 AM
@GypsySpellweaver almost 5:1
 
@Rahul2001 (20-1):(5-1) = 19:4 = 4.75:1, yea close to 5:1. worse odds for the rest of the guys now. Better odds for the gals. Unless one was looking at you, now her odds are nearly infinite against :D

Q: How to download HTTP directory with all files and sub-directories as they appear on the online files/folders list?

OmarThere is an online HTTP directory that I have access to. I have tried to download all sub-directories and files via wget. But, the problem is that when wget downloads sub-directories it downloads the index.html file which contains the list of files in that directory without downloading the files ...

Does anyone here know an online webapplication which will directly download the folder for me.
I just put in the link and I get the download.
I want all the contents of this directory : data.ceh.vn/CEHv9
 
Bob
@Nick If you need recursive subdirectory traversal, you're looking for a 'crawler'
httrack is one of the easier ones to get started with
or you could just use one of the answers over there...
 
@Bob It's required for 2FA.
 
@Bob Used and like httrack, but it's not an online webapplication
 
It's getting really late here. Good night.
 
Bob
@bwDraco 2FA is optional, but the mobile number is not. I suspect it's more to stop people from spamming the free tier.
 
6:19 AM
HEH.
 
Hmm...
 
Bob
@GypsySpellweaver Oh, missed that bit.
That's ... an odd requirement.
 
@Bob yeah
 
Its funny when you see a question, click on it, and the answer is yours.
 
@Bob as easy as wget is, I just want to a paste and get solution. If a webapp is't made yet for this, I think I should probably make one. Would make for a nice project.
 
6:22 AM
@Nick And get all kinds of copyright holders very upset, not to mention the bandwidth you'd use.
 
@GypsySpellweaver google this -> intitle:"Index of" movies
You no longer need torrents. Direct downloads ahoy
I'm not stealing anything here. I'm just helping is all.
 
"helping"
@Nick so you essentially double the bandwidth you use + storage ;p
 
@JourneymanGeek mhh... ok, I sound dumb when you point that out.Here's an even dumber question... Is there anyway I can invoke the wget command from the client system? Security lol
 
@JourneymanGeek client system
 
6:27 AM
._.
I'm missing something then
You can just run wget on anything ;p
 
Web site link triggers browser to invoke wget
 
ah.
er. why would you want to do that though?
You wouldn't always have wget in the same location
 
@JourneymanGeek Hi there, I'm just your average everyday friendly website that wants to ssh into your system and invoke a command that you're too lazy to type. Ofcourse I won't steal your valuables.
 
Preformat the proper line to download the URL supplied by the user
 
AH
^ that
but the problem there is you can't assume every system has wget, or they want to use that or curl...
And you might as well run wget dodgyscript.sh and run it
 
6:30 AM
So, how to cope with having no phone for the next few days, especially given that I have a photo assignment tomorrow? I probably won't have my OP3T until at least Friday.
 
@GypsySpellweaver Is that theoretically possible?
 
@bwDraco don't you have something old as a spare temporarily?
 
Sadly not.
 
@bwDraco get a handy ham radio. All calls are free.
 
@Nick Not likely. JS is rather tight. Maybe with Flash, but doubt that too.
 
6:32 AM
I have access to campus Wi-Fi, but the airwaves don't quite reach the job location.
 
@bwDraco Why not skype for a while. or google talk. Still don't help photos. Got a laptop? Use the webcam.
 
@GypsySpellweaver What I'm seeking does sound like the biggest security flaw in existence. I mean, if you could remotely run commands on a system, you might as well ftp your clients nudes onto your server and blackmail him with it.
 
@bwDraco what do you need it for?
could manage without I guess.
 
Just basic communication, just to stay safe.
 
6:34 AM
@Nick If you wanna blackmail him, make his box download the nasty stuff. Leaves a trail for the authorities to follow. Don't have to assume he has bad pics, give him some instead.
 
@GypsySpellweaver he could purge/rm it as soon as I upload it to his system.
This is all assuming I have access to his/her system.
 
The ISP logs and/or the source server will still have the trail. Especially if it's a government honeypot :D
 
I always have a Nexus 9 tablet with me. It's not the LTE model, though.
Hence, I have an AT&T Nano-SIM that's completely unused for the time being.
 
does it so any cellular networking?
ah, wifi only
I'm a bit slow today
 
@Bob Just used it. Kind of messy because it downloads everything and more. Using wget is easier and frankly, neater.
@GypsySpellweaver Thankfully I don't hate anyone enough to do that... yet
 
6:46 AM
@Nick That's good. Hope you never get there either.
 
Bob
man
 
i'm guessing it thinks the yellow stripy bars are a sign
 
Bob
why are we talking about blackmail
 
@Bob Skip is the proper choice.
BTW< I don't like those things
 
Bob
@GypsySpellweaver Yea, but sometimes it's a toss-up whether Google agrees with the correct choice -_-
 
6:54 AM
Of the three choice for those tests, I think the one I dislike the least is the one where you have to type in the numbers from address signs.
 
Bob
@GypsySpellweaver I hat ethe ones with slowly fading and replaced images.
It takes bloody forever.
