Android Dev

VPNs are awesome :D

My router has a built in OpenVPN server

And I can access my NAS and stuff even when I'm out :)

@NathanOsman raises hand

TheWanderer

@edwinksl oh

ok

David

02:40

I know I'm going to sound like an absolute moron for asking this, but (backstory) - my 640 GB HDD is finally giving up (after 14 years,) and I need to install Windows somewhere else. Is it possible to partition my 3 TB HDD to have two 1.5 TB partitions, and install Windows on one, and Ubuntu on the other?

Nathan Osman

They were selling 640 GB hard drives 14 years ago???

David

It was an IBM computer

My father brought it home from work

Nathan Osman

But to answer your question, yes, you can partition your hard drive that way.

My recommendation would be to create the 1.5 TB partition for Windows and install it first.

David

Ah.. okay

Nathan Osman

Then create another partition with the remaining space and install Ubuntu.

David

02:42

That makes this harder

Nathan Osman

How so?

David

I'm running Ubuntu on the 3 tb

Nathan Osman

Oh, it's already installed?

David

Yessir

Nathan Osman

What partitions do you currently have?

David

02:43

One massive 2.73 TB ext4 partition

Nathan Osman

Ah, how much free space does it have?

David

2.61 TB

Nathan Osman

Hmm... well, it is possible to resize the partition but with that size, it will be unbearably slow.

David

Crud

Nathan Osman

It may be easier to shrink the partition, create a new one with just enough space for your data, and copy it over.

David

02:44

I mean I have a 60G ssd I could temporarily store files on and then start fresh

Nathan Osman

That would be better.

Starting fresh will be the fastest option.

David

Problem is I don't know how I'll format the 3 TB before installing Windows

Live USB?

Nathan Osman

Yes.

Either a bootable USB stick or LiveCD will work.

David

Okay. I'm gonna get everything prepared sighs

Will let you know how all ends up

Nathan Osman

Alright.

David

02:50

Got some time to kill, 20G of info copying from the old drive to the SSD.

It's surprising how much space Windows takes up on its own..

Nvm another 14G on top of that. Estimated 3 hours ;-;

Nathan Osman

How are you transferring the files? Are both disks connected by SATA?

3 hours for 34 GB is unusual.

I could transfer that amount of data to my NAS over the network in less than 10 minutes.

David

Well considering the 640G is on its way out I'm not sure usual is expected

Nathan Osman

Oh, 640 GB.

In that case, never mind. Carry on :D

David

nonono

Just the drive I'm transferring from is badly damaged

I don't think it's exactly optimized

The SSD is probably running into huge chunks of faults or segments in the drive and getting stuck where it normally wouldn't

As well as my motherboard being cryptically old

Kaz Wolfe

03:05

0AD has the best ads.

Mostly because they're the very first package by alphabetical order

David

Okay, all files moved, and live USB created. Off to tear down all I've made in my life ;-;

David

03:38

@NathanOsman Should I have the Ext4 Partition created before I install Windows or?

Ah I'll just assume it'll be good

Nathan Osman

Ideally, you want to have a partition already created when you go to install Windows.

David

Well I have the NTFS one made

but do I want to create the Ubuntu partition yet?

Kaz Wolfe

woot! 100 flags per day!

David

03:57

Wowowow

Seth

@KazWolfe you only just got there?

David

Rekt

David

04:19

@NathanOsman GAH Does windows need to be MBR or GPT?

Nathan Osman

I think either one will work.

GPT would be better though.

David

THats so weird

I tried to install Windows and it said it couldn't install cause the disk was GPT..

and from gparted I cant make it mbr :/

crap

I may have to go full balls to the wall and install only Windows..

Nathan Osman

Which version of Windows are you installing?

David

10

Unfortunately my workplace ITs decided it would be a good idea to create the network share on a Windows 10 only interface :I

Kaz Wolfe

04:53

@Seth yeah :(

i suck

4

David

05:39

@NathanOsman Threw in the towel on Ubuntu for now. Will most likely shrink the ntfs partition and install at a later date. My mind is fried for tonight

Nathan Osman

Okay.

David

I'll need to either post a Q+A about this when I'm done or update a question cause currently it's a shot in the dark

Does any body know why the size of kernel is too large after building it? (actually 12GB)
I didn't enable any features .
Is there any way to reduce the size without facing a problem?

terdon

08:32

@iliya please ask a question on the main site where you can give all the details. We will need to know what kernel, how you compiled it, where you downloaded it from, what hardware architecture, what tool you used to compile etc etc.

iliya

got it! thank you.

ravery

:P

thanks for the info about Ubuntu on windows, though I have a couple questions

Thomas Ward

@ravery AUGR might be a better place to discuss? Also link to context when you're there.

because I've taken a cleaver to about 30 - 60 posts or so today, I need context :P

ravery

got it

@ravery iptables isn't supported by WSL. It still relies on the Windows firewall for many things (think of it as a NAT'd setup, sharing the host network connection for things). There's no solution other than to ask Microsoft to support iptables as part of the WSL. (Remember that WSL uses a tweaked kernel for Microsoft compatibility - iptables support is needed by the iptables package and the netfilter functionality in the kernel.) Closing as a 'bug report' - go contact Microsoft and Canonical. — Thomas Ward ♦ 18 mins ago

Thomas Ward

ah, rigiht.

Journeyman Geek

MODABUSE!!!!

Thomas Ward

@ravery iptables requires kernel support. If the modules don't load proper for the kernel or the kernel has no support for it, you can't use iptables.

ravery

but I have a more general question

Thomas Ward

ask it :0

@JourneymanGeek lies.

Journeyman Geek

14:01

(yeah, that's a legit reason to move stuff)

ravery

I've seen some post that say there isn't really a kernel

Thomas Ward

@JourneymanGeek (In this case Charcoal doesn't need littered with the "Hey can you clarify what you meant on Ask ubuntu" in its room - this is the one time i'm using mod powers to move things to the room it SHOULD be in :P)

(y'know, other than trash destinations for crap posts)

ravery

is ubuntu on windows similar to WINE?

Journeyman Geek

@ThomasWard yeah, but its funny to joke about modabuse

@ravery not quite.

Thomas Ward

:P

@ravery WSL is what I call "black magic"

it's Ubuntu-esque but not pure Ubuntu

Journeyman Geek

14:03

So... windows has this odd thing

where basically you can have different 'personalities' in the system

a very long time ago windows even had a unix subsystem, and an OS/2 subsystem

Thomas Ward

@ravery I am not 100% fluent in the internals of WSL (aka Ubuntu on Windows), but I believe the kernel is just a way for the Ubuntu components to communicate proper with the Windows components.

which is why it's not a true kernel

Journeyman Geek

so now, you have a linux subsystem (which essentially is like a kernel module) that traps some system calls

Thomas Ward

^ that

ravery

well my current impression is that it is a command interpreter shell, ie covert linux call into windows calls

thus similar to WINE which does the reverse

Journeyman Geek

@ravery en.wikipedia.org/wiki/Architecture_of_Windows_NT is a useful starting point.

then read about interix/Wubdiws Services for unix (which essentially was a non linux thing like WSL)

though yeah

you're basically running a windows kernel, with a subsystem atop that, and the linux userland above that

Thomas Ward

14:06

^ that too

Journeyman Geek

so... probably no proper linux kernel there

Thomas Ward

so in effect a WSL "kernel" is not really a true kernel, and is a hackish one that just properly hands off things to the Windows core kernel.

Journeyman Geek

Its almost like a linux container, but running atop a windows kernel

Thomas Ward

^ this

@JourneymanGeek wait, isn't that basically DOCKER shot

grins evilly

Journeyman Geek

ACTUALLY!

I suspect a long term goal for WSL might be just that

running linux containered servers on a windows server base

now, wine has no deep hooks into the kernel

(in fact, I'm half certain there was (once?) a wine windows port...)

Thomas Ward

14:13

shrugs

all I know is that I prefer pure Linux environments to compatibility layers.

Journeyman Geek

lol

Thomas Ward

Which explains why I have two VMware vSphere hypervisors running a ton of VMs.

ravery

right, with wine, the program calls a .dll and the win dll spits out a linux command

Journeyman Geek

this is why I have two PCs on my desk ;)

Thomas Ward

Less compatibility layer issues :p

@JourneymanGeek VMs, man. VMs.

Journeyman Geek

14:14

@ThomasWard my linux box uses far les power and is run 24/7 ;p

my desktop gets shut down when I sleep

Thomas Ward

@JourneymanGeek true, though when you're me and 90% of your VMs run the core infra for your entire network...

... you kinda don't have a choice :P

Journeyman Geek

@ThomasWard I like having many, low powered machines

Thomas Ward

I did that once.

Journeyman Geek

I'm probably throwing in a x86 firewall box in my network

Thomas Ward

It ended up using the same amount of power my two hypervisors now use.

Journeyman Geek

14:15

linux box is a n3060 based NUC machine

and I want the x86 box cause my current router's starting to flake

and internets r important

Thomas Ward

@JourneymanGeek and this is why i have a physical pfSense appliance and a backup failover in my hypervisor :p

Journeyman Geek

@ThomasWard plan is to experiment with a PFsense appliance in my room, then move it over. and in any case, I have a router and half as backup

but $$ :(

Thomas Ward

gotta love free VMware via my university :P

Journeyman Geek

hah

I can just run KVM

@fl

Avery

running KVM is good

it's complicated at first but once you learn it it's easy

Journeyman Geek

14:25

Its free, and suprisingly easy to manage

@UbuntuQuestionsonU&L lol its gone xD

it's literally as simply as chmod 777

(yes I'm sarcastic, don't 777)

(do chmod +rw)

Nathan Osman

Octal FTW.

Byte Commander

Nathan Osman

You'll want that if you run chmod 777 in the wrong directory.

Eliah Kagan

18:58

Is there something even stronger, in case I run chmod 6777?

Nathan Osman

Just increase the quantity :P

Byte Commander

Drink 6 bottles.

Eliah Kagan

My concern is that no matter how much of it I would drink, its owner would become intoxicated instead of me (u+s), and I planned to share it with my friends, the owner's friends would be drunk instead of mine (g+s)! I mean, if the bottle itself is in the directory where I ran the command.

Storing row order in an SQL database is tricky.

Seth

19:23

@NathanOsman why would you be doing that...?

Nathan Osman

19:37

Well, I've got an app that allows users to reorder items.

And the order needs to be stored.

Byte Commander

20:06

add an index column?

Nathan Osman

Meh, I think I'll just use the date the row was inserted.

The user probably doesn't need to reorder that badly after all :P

@EliahKagan My apologies, but back in the stone age when SoftwareRecs was launched, the mods there asked us if we would send software recommendations to them and as I listen to the mods, we did. I stand corrected. (again!) ;-)
