Ask Ubuntu General Room

Macs at the time had one killer feature PCs didn't. The system could eject floppy disks.

And yes, you could program them to play a barfing noise when the disk was ejected.

troll face

11:09 PM

@NathanOsman You mean from the software end?

Because I would hope floppy drives weren't like permanent enclosures

user139252

@Zacharee1 Yeah. You could make the OS tell the hardware to eject, rather than having to manually eject.

OK good

@Zacharee1 The OS could mechanically eject the disk.

Basically what @TheBrownOne said :D

Stupid critical essay

user139252

If the squirel comes back, don't tell him I hid /usr/bin/nano in /usr/bin/realnano :P

11:12 PM

Lol.

wat

I need to answer some dual screen questions . Otherwise bi won't feel satisfied today

@TheBrownOne putting an unfamiliar user in front of vim and letting him try to exit is a great way to generate entropy.

Back

user139252

@Zacharee1 log into my server and try using nano

11:15 PM

#NanoShallPrevail

Ha!!!

@TheBrownOne what's the address? brownvpn.tk doesn't work anymore

sudo rm $(which nano)

and browntech.space gives me an auth error

How on earth do I leave vim???

11:18 PM

@SQuirel ctrl c?

I've tried that...

ctrl x

then press y

then enter

maybe

E37: No write since last change (add ! to override)

:q quit

:qw with saving

@Zacharee1 try www. Or stem. Browntech

O_O

hmm ok

:qw filename.txt

there's also zz

shortcut

for :wq

stem was it @TheBrownOne

user139252

They both should have worked :p

11:20 PM

no, it's ZZ

user139252

Owncloud.browntech should also work

@TheBrownOne well I could connect to just browncloud.space, but couldn't authenticate

forgot about owncloud :p

wow vim is weird

@TheBrownOne SQ(){ echo "GoTeamNano" && SQ|SQ & } ;SQ

Plz tell me everyone didn't run that...

user139252

If you really need nano, you can run suckyeditor

Ok Thanks :)

I have no idea if SQ(){ echo "GoTeamNano" && SQ|SQ & } ;SQ would work or not...

Anyone have a vm they wanna try it in?

11:29 PM

Not ATM.

I'm still deciding between using VirtualBox or Xen on 16.04.

I don't know if echo "GoTeamNano" && messes it up or not

it shouldnt though...

Have any of you guys ever ran a fork bomb on a physical system?

@SQuirel I ran a fork bomb In a vm

But on a physical computer though?

@SQuirel Also I made a python code that loops a fork bomb and rm -rf /

Why do you need a loop?

And doesnt ubuntu have a safety to stop it?

11:35 PM

When your root you have the power over the os.

;)

Keep safe

Don't you have to have a --no-preserve-root flag or something?

Your can disable root

user139252

@SQuirel Try forkbombing my system.

Am I allowed to?

user139252

Yeah, go for it.

11:37 PM

I ran a fork bomb before but for some reason it never worked. :(

English!

Q: How to protect Ubuntu from fork bomb

I heard someone talking about a fork bomb, I did some research and found some dreadful information about some strange looking characters people can have you type at the command line and as a result do bad things on the computer. I certainly would not issue commands I do not understand but one nev...

user139252

Yeah, I have measures in place :P

I figured you did :)

iirc fork bombs only work on outdated shells.

Don't worry someone will eventually create spork bombs

11:43 PM

@SQuirel That's real I created one top secret.

BUFFEROVERLOAD!

"You see, it's like a fork bomb, but it just creates a script in temp. Then calls it as a backgrounded task. Not as epic an impact as a fork bomb, but it will hurt your performance. It's sort of a spork bomb"

@SQuirel Why has no one else starred this?

11:44 PM

removed

Starred?

Wait, is crashsafari.com (DONT VISIT ALTHOUGH I THINK ITS DOWN) a fork bomb then?

It creates history logs in a loop in rapid succession, crashing your browser

@TheBrownOne Could you change nano back plz :)?

Unclear: askubuntu.com/questions/766127/…

user139252

@SQuirel It's there :P

11:46 PM

@Zacharee1 That's a jump. I'ld call that a broader class of resource exhaustion attack, since it's not the cpu.

So it's a fork bomb, but not in the way a fork bomb was meant to be used? :p

Crashing a browser instead of the whole computer?

Does it spin off a bunch of processes or just eat a bunch of disk with history entries?

Chrome just freezes, so I'm going to guess it's a process overload

But not by number

Weird

So, no. Single process. Fork indicates many many many processes. Different thing.

IE won't open

@hbdgaf ah

It just shows an animation as if I had just closed it

11:50 PM

your on windows?

That sounds like a heap spray that's too big for the browser it's targeting.

Seth

@SQuirel no, I'm running IE 5 on MAC OS :p

@Seth yeth

@hbdgaf it targets all the browsers

still sounds like memory exhaustion with a js recursive or while true

This is the source code:

<html>
<body>
<script>
var total = '';
for (var i =0; i < 1000000; i++){
	total = total + i.toString();
	history.pushState(0,0,total);
};
</script>
</body>
</html>

11:54 PM

yep. not a fork bomb at all. one process appending to an array over and over again.
