Troubleshooting

Bob

12:08 AM

@JoeyLópez rsync -v -h -z --progress --partial --port=12000 joey.su.floofyfox.com::files/Win10_1709_English_x64.iso .

could also replace --partial with --inplace

if it gets interrupted, just run it again and it should continue where it left off

Joey López

ok I'll let that run

Bob

yea use inplace

rsync -v -h -z --progress --inplace --port=12000 joey.su.floofyfox.com::files/Win10_1709_English_x64.iso .

when it's done, you'll want to run a sha1sum over it and make sure it matches

Joey López

just gave me details about the file

don't think it's downloading...?

Bob

yea I'm calculating the checksum on my end

1ad928cfef439f6aa4044ddc3a96b0b6830bdd0f  /rsync/Win10_1709_English_x64.iso

Joey López

ok

Bob

12:10 AM

@JoeyLópez what does it say?

should be a progress percentage...

Joey López

rsync -v -h -z --progress --inplace --port=12000 joey.su.floofyfox.com::files/Win10_1709_English_x64.iso
receiving file list ...

it returned to input

Bob

o.O

what OS are you running?

oh

Joey López

Ubuntu 16.04.3

Bob

@JoeyLópez you missed the . at the end

that's a very important . :P

(it's the destination — . represents the current directory)

Joey López

oh that was important... thought it was just ending sentence because people do that kind of weird stuff all the time

Bob

12:12 AM

yea, I tried to include it in the code block but that's not obvious in chat formatting

Joey López

ok here we go

Bob

you could pass in an actual dir instead, like /foo/bar

Joey López

idk how to do checksum stuff, though these days perhaps I should

Bob

@JoeyLópez sha1sum file.iso

just make sure it outputs 1ad928cfef439f6aa4044ddc3a96b0b6830bdd0f

Joey López

oh... that's easy

Bob

12:14 AM

since the rsync server I set up is unauthenticated (didn't want to bother with ssh)

(and if you don't trust me, google for that checksum and you'll find it in win10 iso listings)

Joey López

the max speed it's hit has been 1MB/s...

Bob

should take a little over an hour then

Joey López

I'm guessing either you throttled the bandwidth to make sure your internet remained usable, or you're a long way from the east cost

or my internet is acting up again

Bob

@JoeyLópez erm... it's hosted on a server in Amsterdam

Joey López

oh

Bob

12:16 AM

I can chuck it on a Canadian server if that'd be faster

Joey López

idk

Bob

but ... are you sure you're not mixing MegaBytes and Megabits? :P

~20Mbps is a max of ~2MB/s

Joey López

16Mb/s is 2MB/s, right?

Bob

give or take, yea

Joey López

I know my wifi is faster than 8Mb/s

internet*

the router, and supposedly the wifi

Bob

12:17 AM

I only picked the AMS one cause that was the most accessible

I don't have lxd installed on the CA one o.O

anyway, an hour is probably faster than setting this up

Joey López

the bandwidth I'm supposed to have is either 200 or 250Mbps, and my laptop's wifi maxes at 150... so this is fun

oh it's staying above 1 MB/s now

that's good I guess

Bob

@JoeyLópez actually, if you want speed, UDR would be best

there's all sorts of ways to speed things up

Joey López

UDR?

Bob

github.com/LabAdvComp/UDR

fancy stuff

but tbh it's probably not worth the trouble

Joey López

yeah, I don't use rsync on a daily basis or anything

I'll just let that run for now

Bob

12:20 AM

I've used it before to push a <100kB/s rsync up to >5MB/s

it's great for Long Fat Networks like this one :P

Joey López

huh

Bob

(i.e. plenty of bandwidth from both ends but TCP isn't optimal for long delays from crossing oceans)

Joey López

yeah...

yea uh... definition of LFN? :P

Joey López

pretty much...

thought it wouldn't help to bring it up above 2MB/s or so, because I think Linux and Aetheros wifi don't cooperate, limiting my bandwidth to 16-20Mb/s

Bob

12:30 AM

@JoeyLópez if you want we can test your UDP bandwidth

apt install iperf

Joey López

nah, maybe later

just gonna let it be for now

Bob

iperf -c joey.su.floofyfox.com -p 23223 -u -d -b 1000m

Joey López

might do that in a bit, if it takes a long time

Bob

if that's significantly higher I can set up UDR

@JoeyLópez nah, it's about a minute

Joey López

oh

Bob

12:35 AM

If you're running it, there should be two "Transfer" entries. One for up, one for down.

also, if the rsync transfer gets interrupted, don't forget to resume it

Joey López

the speed checking command isn't doing much

Oh, never mind, it was done- it just didn't show that it was accepting input

until I used Ctrl+C without shift

Bob

...hm. you don't seem to be able to receive UDP. probably some misconfig in a firewall somewhere.

or on my end. yea, probably not worth bothering with UDR

Joey López

yeah

Bob

1:16 AM

@JoeyLópez how's it going?

there should be an ETA

Joey López

it's at 26%

like 100kB/s...

5-10 hours eta

Bob

oof

uhm

@JoeyLópez Do you want to give UDR a shot? Or try downloading the ISO from the MS website again?

Joey López

1:38 AM

Gonna try MS website from laptop and see how it goes

Bob

k

Joey López

well the exe downloaded in seconds, and I have wine

should I run it or get the iso?

Bob

@JoeyLópez you need the iso

MCT doesn't work in WINE

Joey López

oh

figures

so just copy it over once it downloads?

Bob

@JoeyLópez in this case you'd want to extract it to the flash drive

normally you'd install it properly but since we're doing an upgrade the drive doesn't need to be bootable

Joey López

1:42 AM

oh ok

would just copying it over work?

Bob

@JoeyLópez you need to extract it

you want the contents

Joey López

ok

Bob

the ISO file itself isn't gonna do you much good

Joey López

just asking

Bob

1:59 AM

@JoeyLópez basically you want to extract it (google, 7zip, mount, etc.) to the flash drive, go to windows, and run setup.exe

make sure you choose in-place upgrade and not clean install

Joey López

of course

12 minutes left to download normally

Bob

2:16 AM

*12 minutes later~*

Joey López

hey it just finished

folder should be named cccoma_x64fre_en-us_dv9 right...?

doesn't match iso name but whatever

Bob

@JoeyLópez uhh... you probably want the contents of that folder?

doesn't really matter as long as you have the setup :P

Joey López

yeah that's the name of the folder that got mounted

I'm pulling the contents out

Joey López

2:44 AM

ok copied over

Bob

@JoeyLópez reboot into windows, run the setup

Joey López

just gotta swap drives real quick

so what now

just boot as if normal?

@Bob

Bob

3:06 AM

@JoeyLópez yea, just get into that narrator-cmd again

Joey López

ok

what now

Trouble Maker Chat Broom

escape backtick in a comment to actually show the backtick, how do I do that?

I want to show rn for example

But where that's backtick "r" backtick "n".... should I ask meta?

Joey López

I... what?

oh

Trouble Maker Chat Broom

3:22 AM

Sorry, I think I may have posted here thinking it was something else... Is this a room created for general troubleshooting or something created for something else. I may be wrong to post here

Joey López

I think this was created off of my question, linked on the right there

Trouble Maker Chat Broom

Sorry about that Joey, I saw @Bob with you and the title troubleshooting and thought maybe he created it, etc. My bad.... I may post a meta question on this and be more clear if I cannot find anything with search on SU meta.

Joey López

@bob how do I run it :|

Bob

@JoeyLópez cd /d to the drive it's on and run setup.exe

Joey López

Setup couldn't start properly. Please reboot your PC and try running Windows 10 Setup again.

Bob

3:38 AM

...

urk.

hmmmmmm...

@JoeyLópez remind me which exact runas command you've tried, and what happens when you try?

Joey López

runas /user:<my username> cmd

Bob

@JoeyLópez and the exact error?

actually. take a photo.

Joey López

hold on

Bob

I want to see what kind of window it appears in.

Joey López

the runas error?

cmd

Bob

3:41 AM

yea

@JoeyLópez does it ever prompt for a password?

Joey López

yes

Bob

have you tried adding a new user using net user?

Joey López

and it's freaking impossible to type anything due to window focus, I can sometimes get it to stabilize by keeping a steady stream of input

yes

attempting to start cmd as user "JOEYS-FLEX3\<main username>"...
RUNAS ERROR: Unable to run - cmd
5: Access is denied.

Bob

@JoeyLópez what happens when you add the new user?

Joey López

it adds it but runas returns the exact same error

even if I type a user that doesn't exist it gives me that error

Bob

3:51 AM

... hmm.

soooo user login seems screwed

Joey López

I have to go...

Bob

probably the same reason the login screen won't appear?

Joey López

but yes indeed

Bob

psexec might get you out

Joey López

I opened taskmgr to try to figure out what on earth is causing window focus blink, but I got nothing (and yes it opened, just as default profile)

syntax?

winlogon is running, as well as wininit

just in case you wanted to know that

Bob

3:56 AM

@JoeyLópez docs.microsoft.com/en-us/sysinternals/downloads/psexec

download that and extract the zip

(you can unplug the windows installer flash drive and download on the chromebook)

then run psexec -i -u <username> cmd

hopefully that'll get you in, but... ugh

depending on what exact point is broken...

Joey López

this is a fine mess, isn't it?

Bob

@JoeyLópez could continue another day. or consider saving your data and reinstalling...

@JoeyLópez ayup. It's not quite broken in the right places for sfc/dism to fix, but it's broken enough that the sidegrade isn't working

Joey López

oh hey, it's sysinternals. That's familiar.

Bob

@JoeyLópez you could also head into C:\$Windows.~BT and C:\$Windows.~WS and see if you can find the log files (setuperr.log, setupact.log)

Joey López

I'd have to get back to linux, wouldn't I?

Bob

4:01 AM

Oh and look in C:\Windows\Panther\ for the same two files

Joey López

ok

Bob

@JoeyLópez you could probablymaybe do it from the cmd

Joey López

what do I type for the command?

Can't scroll up on cmd for whatever reason

ahaha I'm stupid I closed winlogon.exe from taskmgr... closed all the windows (sight)

sigh*

Bob

@JoeyLópez you can right click on the title bar => properties => layout tab => increase screen buffer size (height)

@JoeyLópez dir and cd to explore in there ... or do it from linux

maybe leave it for another day - it's getting late over there, yea?

Joey López

I mean for psexec

yeah...

Bob

4:05 AM

@JoeyLópez psexec -i -u <username> cmd

Joey López

"over there" sounds like you're referring to another country... which I guess you could be

ok thanks

Bob

@JoeyLópez I'm in Sydney, AU :P

Joey López

ah

yeah it's getting late over here

Bob

basically, the goal here is to try to figure out what exactly is broken that's blocking the upgrade setup, and try to get it to run

Joey López

see this is why you're running at full mental capacity at 11pm... because it's not 11pm where you are

ok

Bob

4:06 AM

alternatively you could also ask over at sysnative.com/forums/windows-update — I've never been there personally but they seem to know what to do with a lot of these issues (corrupted system files, etc.)

Joey López

Blocked on the Chromebook...

of course

DNS server not authoritative for zone.

uhh

oh I'm on C:\Windows\System32

PsExec could not start cmd: Access is denied.

Bob

sigh

Joey López

Would backspacing a ton before typing my password affect anything? Because that's the only way I can get the window to accept my input for more than part of a second.

Bob

shouldn't be a prob

and didn't you create a new account with no password?

Joey López

oh I can make it without a password? oops

ok let's try this just in case

still asked for a password

ok well I'm going to try again tomorrow...

thanks for the help

@JoeyLópez Windows reports max link speed, doesn't mean you can actually receive data at that speed... Hard drives write at 1,000-1,600Mb/s typically.

@Bob Sounds like something I need, but wtf is UDT?

@JoeyLópez He's in Australia, a long way from Anywhere(tm)

@JoeyLópez Linux and Atheros co-operate the best... Which is why most true Linux routers run Atheros.

@JoeyLópez I run at full mental capacity at 11pm regardless.

@Bob You should have asked for a photo (again). Sounds to me like setup would run, if anything would run

I mean it just sounds like executing anything doesn't work. For some reason. Yet running cmd does, maybe rename setup.exe to narrator >_>

Screw psexec. Setup has to UAC to Admin anyway

Bob

2:12 PM

@FMLCat A custom TCP-like protocol that's not TCP. Runs over UDP 'cause a new IP protocol wouldn't work on most routers. Unlike TCP, optimised for bulk data transfer over LFNs.

@FMLCat well, he was running as system, not aa normal (or admin) user... idk if setup works as system

idea was to runas/psexec into a more normal user first but apparently that's broken too

Journeyman Geek

Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shit.

Joey López

9:11 PM

@FMLCat I can run taskmgr from cmd, and open cmd.exe from there (the title of the resulting cmd is no longer "narrator.exe"), I just can't seem to use runas... or the setup. Also, trying to run explorer.exe from the task manager will end in it closing before doing anything.

I guess it must just be a few specific Atheros chips that I heard don't (or didn't) work well with Linux?

Joey López

10:34 PM

oh also, I wasn't talking about windows' link speed. I believe that was reported at like 300Mb/s, but xfinity's speed test (what I was talking about) reported 150Mb/s on Windows.

@JourneymanGeek basically

Joey López

11:07 PM

hold up...

might be a terrible idea, but would it be worth at least trying to add SYSTEM as an administrator?

FML Cat

11:23 PM

@JoeyLópez But that would make the maximum realistic speed of your wifi adapter to be about 220Mbps, not 150...

But anyway

Joey López

11:46 PM

so... any ideas?

so SYSTEM can't be added to user groups
