That's debug output from my script, not from shred

@BenStumpf you ever hear of the famous Simon Stumpf in the Reformation?

user136984

My ears aren't that great, is there any chance someone could have a listen to this song and tell me what it is about?

user136984

Sabaton - Ghost division

@JamesTobin Nope

@BenStumpf ever hear of Ulrich Zwingli?

user136984

6:02 PM

Because I'm very confused, half of the time it sounds pro-Nazi, and half the time is sounds anti-Nazi and they appear to change very quickly, but then that's only from what I can make out from the song. But after reading some of the comments I am thoroughly confused.

@BenStumpf what's the actual script you're trying now? There's no such debug output in the script in the answer.

Just paste the script directly here

insert_name_here

it's the one from my answer

#!/bin/bash
lsblk -ld | grep -o '^sd[b-z]' | while read -r filename; do
    filename="/dev/$filename"
    echo "Processing $filename"
    if (hdparm -i "$filename" > /dev/null 2>&1); then
        shred -fvz "$filename" > /home/ben/ProjectsInProgress/ShredLogs/$(hdparm -i "$filename" | grep -o 'SerialNo=\S*' |cut -f2 -d=).log 2>&1 &
    else echo "Ignoring $filename"
    fi
done

user136984

Because I don't want to be listening to pro-Nazi music, however even though it does seem to be praising the German tank 'elite', they are actually signing anti them in the second half of the song so I am now very confused.

#!/bin/bash
logpath="/home/ben/ProjectsInProgress/ShredLogs"
lsblk -l | grep -o '^sd[b-z] ' | while read f; do
    logfile="$logpath/$(hdparm -i "/dev/$f" | grep -oP "(?<=SerialNo=)\w+")"
    shred -fvz "$f" &> "$logfile"
done

@BenStumpf I edited mine, try it again

gah.

why the hell can't wsl use systemctl

all i want is gitlab, and it seems to be impossible :/

user136984

Also, I think today is the Yakkety DocumentationStringFreeze. Is that correct?

@BenStumpf What happens when you run that one? That's the one I had a hand in writing.

@ParanoidPanda Yep.

@terdon eek. you did? I am so checking that for dubious code :+

A: How can I shred all disks but /dev/sda and log the output to a file?

This script should do what you want. Note that it must run as root! #!/bin/bash logpath="/home/ben/ProjectsInProgress/ShredLogs" lsblk -l | grep -o '^sd[b-z] ' | while read f; do logfile="$logpath/$(hdparm -i "/dev/$f" | grep -oP "(?<=SerialNo=)\w+")" shred -fvz "$f" &> "$logfile" done ...

are you trying to wipe usb drives?

6:08 PM

@BenStumpf Looks like it's working although it's a mite too fast.

running two is hard work sorry

@ParanoidPanda it should be frozen at 2100 or so

don't quote me on that though.

Right!

The one Byte started gets HDIO_GET_IDENTITY failed: Invalid argument

@BenStumpf Of course. No problem

6:09 PM

i got thoughs backward sorry

insert_name_here

@BenStumpf that error is normal for USB drives...you can't use hdparm on them. you'll have to find another way of naming your log files if you're dealing with USB drives

no hhds via usb

i have hhd docking stations

@Downgoat Very carefully.

one moment something started working but ive been getting errors

is there a way to see what is using the drive?

insert_name_here

ok

6:12 PM

though no new logs have been made

insert_name_here

I think shred is working but the logfile isn't

yep

insert_name_here

i think i know how to make the logfile work for USB HDDs...just a minute

is there a way to tell what process is working on which drive?

nvm

@BenStumpf sudo lsof /dev/sdN

insert_name_here

6:16 PM

ok

That should show you who's accessing the drive

insert_name_here

Log files should work now

Q: Mirror ubuntu repos from Linux Mint

I have a desktop with Linux Mint 18, and a number of PCs with Ubuntu server 16.04 installed. For security reasons, only the Linux Mint desktop has access to the internet, while the server PCs are connected only to the Linux Mint desktop. I want to mirror the ubuntu repo on the Linux Mint desktop...

server mint apt-mirror

is this OT or OT? >:-D

@insert_name_here That worked but the log file names were a mess S1D15ZGT .log and L3ABFZMG L3ABFZMG.log

@BenStumpf do insert a name there :P

insert_name_here

6:35 PM

@BenStumpf there was a space between the T and .log? weird

I just made this account and wanted to get started, ill change it later if i can

huh, those drives are reporting weird serial numbers

i can limit the serial number to only the first "word" (string of non-space characters) if you want

6:42 PM

I have drives that will have longer s/n

does that matter?

so. can we get a mod to change this room name to apt chat ubuntu?

for example WD-WMAL93928092

insert_name_here

they should work fine as long as the first "word" is unique

insert_name_here

i don't know why drives would report a serial number with spaces in it...does anyone else know if that's abnormal?

6:45 PM

I can't think of any reason why that would not work

insert_name_here

@BenStumpf OK try it now, it should only use the first "word"

very nice

ty very much, checked and up'ed

insert_name_here

you're welcome

I'll remove the debug output now

does anyone know a good resource on regular expressions for someone who knows very little about them?

@insert_name_here I'm getting a HDIO_DRIVE_CMD(identify) failed: Invalid argument

7:04 PM

@BenStumpf cheatography.com/davechild/cheat-sheets/regular-expressions/…

and the script ended far too quickly sorry about the fail success

insert_name_here

hm, is there any output before that?

yes it was the same as before, that was after i put the script into a bg proccess

what was the "Serial number without grep -o, cut, or sed"?

checking the drive that matters for that dock

insert_name_here

yeah, it looks like that drive just got suddenly disconnected

i don't think that error could be caused by the script being bad

yep

its the dock, thank you for being so helpful

I really think that the qTox developers have crossed a line:

user136984

First they stop providing their package to Linux because of a personal argument and just say that people should switch to Windows, then they are rude to their users, show private communications with screenshots where they are using the f word and other such foul language, and now after being criticised for basically never fixing anything, they are rude to a developer.

user136984

"trying to promote crappy uTox" is not the sort of thing rival mature developers should say to one another.

(CC: @cl-netbox)

yesh that is rude indeed

@NathanOsman would you be willing to host some sort of analytics if I made a script? It'd be interesting to see how many people use it if I announce it on Meta (if I can do that)

That looks like a whale @edwinksl

you are getting out of hand is what it is

@Seth oh come on, I think that deserves a star :p

@edwinksl well I think I fit my description

5 hours ago, by Kaz Wolfe

@ParanoidPanda it should be frozen at 2100 or so

fun fact: earwigs are horrible

@KazWolfe did you actually have one go in your ear?

because that's supposed to be rare

@Zacharee1 no, they completely infested my telco terminal block

oooh fun

10:41 PM

as in, it was literally packed full of earwigs. Everywhere. In the connectors, behind things...

lol

so i had to re-caulk that.

And there are now about seventy cryogenically frozen earwigs on the ground by said box.

"Get Telco. We have tons of 'features!'"

@KazWolfe Did you blast them with a fire extinguisher or something? o-O

@Zacharee1 compressed air thingy

ah

10:42 PM

upside down. so... yeah.

yay cryogenics!

Q: SSH only works/keeps alive while ping running in background

A brand new linux box running Ubuntu 16.04.1 (LTS) Server was installed into a Citrix VM. It was set up with openSSH. When connecting to it via, it will timeout. This happens even immediately after I exit a live ssh session and try to ssh again. If I'm in a session, it will often cut me off, wi...

ubuntu ssh ping timeout

@KazWolfe is there a picture of that? i would like to see how it looks like

@edwinksl i don't want to look that up

heh, understandable

@Zacharee1 oh, and some butane too for good measure.

because earwigs suck

10:47 PM

lol

@edwinksl noooo!!! "what it looks like" or "how it looks"!! Not both

@edwinksl next time i have to cryo-freeze the box, i'll remember to take a picture of everything

the problem with them is they pack in real tight. One cubic inch can hold a lot of earwigs.

there were probably upwards of 300 in that box, and one-third are now waiting for us to discover how to un-thaw things stored cryogenically.

on that note though. DSL is cheaper than my current ISP, and double the speed.

So now I want to figure out how to trunk two DSL lines together :D

@Zacharee1 hehehe so now i know what triggers you

DSL, cheap AND faster? waaaaat

@KazWolfe dual wan router

@Zacharee1 i have one of those. in fact, i have lots of those.

mods! hide!

@KazWolfe use em

10:51 PM

i just have never used the dual-wan feature.

@Zacharee1 6Mbps for 30 (DSL) vs 3Mbps for 65 (current WISP)

o_O

Cooool

though our wisp can give us up to 30, but they're annoying and will charge a literal arm and a leg for that.

My stagrecraft teacher is letting me draw a sketch on my tablet

but i dont know if i want to go back to AT&T

i like my static IP lol

WISP == Wireless ISP?

10:52 PM

@Zacharee1 yep. you can guess how good they are.

and that explains the price

lol

Who is it?

some local thing that I'm not telling you because it gives you a really good idea of exactly where i live

the trust in this one

as in, you'll get my home down to a 15 mile radius

I don't think you're high-profile enough that someone will want to look through the whole area to find you :p

unless you are.... o_@

10:54 PM

but yeah. and the problem with them is we need to buy the equipment

heheheheheh

they just remote in and force us to hand it over, and they configure it and slow everything down

lolol

i kinda want my nice ten-mile wifi thingy back.

o_O

wat

10:55 PM

that thing can reach 10 miles LOS

What can?

hang on let me find a picture

user image

I should probably clean it...

how is a 10 mile WiFi network legal?

FCC permits, ISM band,

specialized equipment needed

huh

10:59 PM

(hence the dish lol)

That one specifically can hit 18 miles

(or 30km for people with useful measurement)

@KazWolfe AirSpeed?

@Zacharee1 ubnt.com/airmax/nanobridgem

Ubiquiti equipment is actually really good. Once I get our network in a good state, I'll be getting a nice AP from them

nice

wait, Ubiquiti

Yes.

They have enterprise WAPs too right? For schools and businesses?

11:10 PM

yep

that's what i'm getting lol

@KazWolfe How tight is the beam on that dish?

i don't need one of these for my home wifi

@RobotHumans honestly not sure

and I wonder if they'ld let me mount the far end of a point to point at the dslam ... I can only get 10Mb out here. would be nice to get it to 150, and sell the excess to the campground so everybody could get cheap high speed

they'll let you mount it i think, but maybe not connect to anything

you need a high-power transmitter too

eh. they sell rackspace in the dslam here. so, if they sell the rack space, they'ld let me connect it. i'm concerned they wouldn't let me mount it

11:15 PM

dl.ubnt.com/datasheets/nanobridgem/nbm_ds_web.pdf

there's the DS for it

ty

you just need a clear line of sight.

this thing can't go through anything. A single tree kills it

that is usually the way with highly directional ptp links

there's a tower across the street. i could get the elevation i need there.

can you run the cable that far?

not realistically. but i could use consumer grade stuff to hit it then instead of the commercial grade stuff.

11:25 PM

need one more CV askubuntu.com/questions/825462/…

@Zacharee1 technically we could have duped it to the how to install ubuntu on a chromebook question and edited out kali... but i suspect that would have started a fight

o/ @Mateo

hi @RobotHumans

@RobotHumans I don't think it's valid to remove Kali from that though (case in your point here). The installation for that is pretty different from Ubuntu, and we wouldn't be answering OP's question

I just thought I'ld write that down, so if someone contests the close and they check the chat log - they can see we thought about that alternative.

@Zacharee1 do you have more details about this analytics thing?

11:37 PM

@NathanOsman just like how your chat script works, where it has a live updater for how many people have the script active, and possibly how many sites it's used on, if I end up making it for multiple SEs

What does it track?

Well I haven't actually made anything :p. Couldn't it do some sort of polling thing every 30 seconds or something, where the script, when installed, pings a server to tell it that it's there?

sigh, why can't people do even a single Google search before hijacking forum threads?

someone just asked on the XDA KingRoot thread if there are any rooting apps that work for the T-Mobile Note 4

Does anyone here work at a large ISP? Because I need like 10 miles of fiber line.

So... someone would install the script and it would send pings when the user is on Ask Ubuntu telling us which page they're on?

@KazWolfe Nope. Although there are times when my house feels like an ISP. ("My Internet is busted! Halp!")

really. why is it so hard to buy just fiber line?

11:48 PM

I'm sure you could get 10 metres, but 10 miles...

that's a lot

put it this way. i'm willing to run my own fiber just to deal with my crap internet.

It's not that simple - you need special hardware at each end.

It's more than just the cable.

And for long runs you need repeaters as well.

distrib point is about 10 miles away, and i can probably get the needed equipment.

O_o

Are you an ISP? :D

state of CA has a lot of surplus garbage :D

11:50 PM

Maybe it would be easier to move your house to a place with better internet than to get better internet to your place.

What about cable tv?

but this is why i'm not a backbone engineer. because that stuff is confusing as hell

You can also get internet over tv cable.

@ByteCommander if there were a TV cable run.

Living in the middle of nowhere, literally, has its downsides.

Satellite is always an option.

:P

@NathanOsman i'd rather go up from my WISP

11:52 PM

Sure, it'll cost an arm and a leg, but it's an option.

user image

"middle of nowhere" sounds so poetic. What we in Germany call that would literally translate to "near the ass of the world"...

@NathanOsman no, just if they have the script installed. If I make templates for other SE sites, like SO or U&L, then maybe it can have a detector to count the number of sites it's being used on currently

@ByteCommander we're near the pimple on the ass of the world.

Ah, nice. How is the view from up there?

@ByteCommander up? o_O

11:54 PM

not that bad. if we weren't on a site where literally nothing ever goes away, i'd send a pic

deleted messages go away

what about Discord?

@Zacharee1 A pimple is normally standing up from the otherwise rather flat surface of the skin, right?

@ByteCommander oh, I thought the ass was up :p

Depends.

There was a funny tv ad about this from an online furniture shop. Let me find it...

...

@ByteCommander what's the German phrase?

11:58 PM

Home24 Möbel TV-Spot / Werbung: Am Arsch der Welt

@Zacharee1 "am Arsch der Welt"

lol

Well now I know where we get ass from
