@Zacharee1 Try it.

Zacharee1

@terdon Not in Ubuntu and no thanks

terdon

$ sudo rm -rf /
rm: it is dangerous to operate recursively on ‘/’
rm: use --no-preserve-root to override this failsafe

Zacharee1

huh

Then why do so many people have trouble with it?

terdon

rm won't remove / unless you use --no-preserve-root. It hasn't for quite a few years now.

@Zacharee1 They don't. They think they would.

Or they did rm -rf ~/ or similar. It will break most things. Including /boot, /etc /usr` and so on. Just not /.

It's in the POSIX specs.

Terrance

Yeah, but putting the /* is very dangerous

Seth

00:03

or rm -rf ~/$STEAMHOME ;)

Terrance

I just ran it in a VM safely, and bam no more boot in the VM

Seth

@Terrance globs are extremely dangerous.

Terrance

@Seth Indeed they are! =)

Glad I have VMs to play with that can be easily set back up. =)

Terrance

00:15

Suicide Linux can be quite brutal.

Zacharee1

@Terrance Why would someone make that?

Terrance

@Zacharee1 Don't know. Maybe it should be called "Roulette Linux".

One more dangerous thing I can think of would be running the sudo rm -rf with the /* on a WUBI installation since it has a /host folder that is your hard drive. It would obliterate everything!

Lucio

00:47

I'll just leave this right here.. github.com/NARKOZ/hacker-scripts

/cc @hbdgaf

Zacharee1

That again?

Lucio

Sorry buddy, what do you mean?

terdon

@Seth Oh, that was that mindbogglingly stupid bug where they weren't checking whether the variable was defined and ended up deleting everything in ~/ right? Idiots.

Mateo

@NathanOsman lol, that was awhile ago

Nathan Osman

Yup.

Zacharee1

00:59

@Lucio It was brought up about two weeks ago

Mateo

other news I sent off the email recommending the touchscreen kiosks, and stands, should be a cool project

here is the stand: displays2go.com/P-23320/…

found the source code for the touchscreen, and got it working as well

Zacharee1

nice

Mateo

I should write a post or something if I have time for it, the documentation had a lot of information for old Linux distros was hard to see what needed to be done

including a .exe file that was actually an archive...

Seth

@terdon yes on both counts.

xD

terdon

That's why you don't get people who put "MS Word" under "Computer skills" in their CV to write your code for you.

Seth

01:08

ikr

Zacharee1

ō_ô

@NathanOsman That's me :p

Mateo

tables for steps was intresting, it did make comments for the code kind of nice though I think markdown style might be better google.com/url?sa=t&source=web&rct=j&url=http://…

so, I totally should remake a simpler how to for it just targeting Ubuntu

@NathanOsman that is the "in" color right now websafe version ;p

Nathan Osman

01:24

:P

Mateo

lol, remember when you had to worry about people that had only 256 colors

Zacharee1

Someone just asked why downgrading iOS wasn't working for them on a thread about the new jailbreak for iOS 9.0

If that isn't thread-jacking, I don't know what is

Zacharee1

Some interesting rounding and math by Gmail

Thomas W.

@Zacharee1 lol

downgrading ain't possible xD

not easily

Zacharee1

@ThomasW. Unless you're iH8Sn0w, not at all

Thomas W.

Zacharee1

except for the 4S, which can go to 5.0.1 or 6.1.3

For some reason

@HeatherBrown I have resurrected my server :p

Seth

@NathanOsman I figured it all out...

@NathanOsman not sure what I did, but it works...

3 messages deleted

whose idea was it to put the delete room button right above the delete messages one? -.-

Journeyman Geek

Did you nearly accidentally the room?

Seth

@JourneymanGeek yeah xD

Nathan Osman

This is bizarre.

Suddenly my desktop only does 100 Mbps.

It's only negotiating for 100 Mbps with the router, instead of the full 1 Gbps.

I wonder if this has anything to do with the virtual bridge I set up...

nathan@nathan-desktop:~$ sudo ethtool eth0
Settings for eth0:
	Supported ports: [ TP MII ]
	Supported link modes:   10baseT/Half 10baseT/Full
	                        100baseT/Half 100baseT/Full
	                        1000baseT/Half 1000baseT/Full
	Supported pause frame use: No
	Supports auto-negotiation: Yes
	Advertised link modes:  10baseT/Half 10baseT/Full
	                        100baseT/Half 100baseT/Full
	Advertised pause frame use: Symmetric Receive-only
	Advertised auto-negotiation: Yes

At least two things there are configured incorrectly.

Wake-on-LAN (WOL) is supposed to be enabled.

And the "Link partner advertised link modes" is incorrect.

Ah, silly me. I used the wrong cable.

Seth

I've totally never done that before wink wink

Nathan Osman

Nooooow we're getting speeds closer to what I expected.

@Seth So apparently CAT5 != CAT6 :P

Now to fix the issue with Wake-on-LAN...

Ravan

ANy mod available here?

@Seth ?

@Seth @fossfreedom Its serial voting askubuntu.com/users/439451/ravan?tab=reputation

I just opened AU I got 100 rep, Its very odd

Seth

hi @Ravan. Let me take a look.

@Ravan Yes that does look like serial voting. The system should take care of it sometime tomorrow. Don't worry about it :)

Ravan

@Seth Its really odd

my rep bar looks weird

How to know, who?

Seth

There is no way for you to tell who.

Sometimes moderators can tell, but that isn't public information.

If necessary we will contact the offending user and let them know that this isn't ok.

Ravan

do the last one,

please

thanks @Seth

Seth

Ravan

Seth

Ravan

Can I post suspect user here?

Seth

well.

no. How about you flag one of your posts with that information?

Ravan

I will do now

Seth

A.B.

@NathanOsman do you know a good WordPress LDAP plugin? For WordPress multisite.

Behind LDAP is Kerberos.

Nathan Osman

Nathan Osman

Hi Everybody, Is anyone able to look more in depth at why I'm getting the following notice "Wait! Some of your past questions have not been well-received, and you're in danger of being blocked from asking any more."

I don't have any negatively scored questions, and I don't think I've ever deleted any.

@hg8 the swastika was adopted by Hitler, but has a much deeper origin and wider usage that just by the Nazis. en.wikipedia.org/wiki/Swastika

fossfreedom

@ryanjdillon - you dont have a Ask Ubuntu profile - probably should hop into a StackOverflow chat room and ask a mod there to help you - maybe this chat.meta.stackexchange.com/rooms/89/tavern-on-the-meta

Neil

@fossfreedom he has a Ask Ubuntu profile

@fossfreedom askubuntu.com/users/109484/ryanjdillon

fossfreedom

09:58

ahh yes - I was clicking from chat - didnt show up from here for some reason

ryanjdillon

My score isn't high enough to see downvotes on my questions, so maybe I have more negative points than positive, despite a positive rating?

fossfreedom

@ryanjdillon - you've got two autodeleted questions - probably because the system thought you abandoned them.

ryanjdillon

Hmmm... I haven't heard of this. What's the best course of action to keep myself from getting blocked from asking questions?

fossfreedom

when you ask a question - keep revisiting it every couple of months to update it with your investigations.

... additionally if you are not getting any views - pop into here and ask for some help on how to improve the question. Edit the question with any responses

--- consider bounties to get more attention

ryanjdillon

Great. Thanks!

As an aside, I went to ask a question that I swore I found an answer for before, but no I can't find it, so I'm afraid it will just be marked duplicate if I ask.

my drives in /media/username/ keep getting renamed from /media/username/label to /media/username/label1,2, etc.

fossfreedom

10:06

if google doesnt find your question (remember to suffix with " site:askubuntu.com") then pop into here and ask before you post - someone usually here can say "yeah its been asked before"

ryanjdillon

Ok, thanks @fossfreedom (and @Neil)

user136984

@hg8 Why wouldn't they be?

hg8

@ParanoidPanda I don't know. That's true, it's not only linked to hitler.

user136984

Hitler used the Buddhist peace symbol because he thought it was powerful, he also flipped it over. And the one which is flipped his way with the dots in it is an Indian peace symbol. And I guess that they just provide them in every flipped round way that they can...

user136984

11:00

Still not too sure where those symbols would come in handy though... :P

user136984

I haven't ever needed to send anybody those before and they are banned in some countries...

hg8

@ParanoidPanda That's what I was thinking too

@ParanoidPanda Yes it's banned in france

@ParanoidPanda thanks for the clarification

user136984

But these were originally peace symbols, we shouldn't forever associate them with Hitler, we'll just allow him to ruin something else then...

hg8

Of course.

user136984

There are all sorts of things, such as his name, I don't think that we should reserve that name only for him now, we shouldn't give him special treatment, the name should just be treated as an ordinary one that goes into use one day again. And there are other things like their salute, which originally was a Roman salute. I don't think that all these things should be banned and associated with him and the Nazis for ever.

user136984

11:06

I mean, it all happened rather recently so maybe now is not the time, but we shouldn't keep it this way for ever giving them special treatment. I don't know, you might disagree with me.

user136984

Poor Romans though... Look what happened to their salute and it's banned now!

user136984

And they've even banned the moustache now for god sake!

user136984

Not that I really want the moustache, it's not exactly very nice...

hg8

I see what you mean but it's debatable.

user136984

When is 12.04 going to go EOL? It's really been around too long...

fossfreedom

11:44

@ParanoidPanda - at a guess probably that question was general networking orientated

user136984

11:56

@fossfreedom: But I was using Ubuntu, plus I have been told in the past that questions about things on Ubuntu that could be asked about the same thing on Windows etc are on-topic here if I ask about them on Ubuntu.

fossfreedom

yep - as I said - "I guess" - especially given the answer you accepted was about doing stuff with your router - nothing todo with ubuntu.

personnally I am relaxed with the Q ... 5 others obviously were not.

user136984

Well, that was because I was doing the right thing, but I would need to either do it from my router, or directly connect my machine to the internet because of my router doing the NATing thing.

A.B.

@cl-netbox a working plugin

cl-netbox

@A.B. do they not work ?

A.B.

nothing of them works and I have no idea why. ldapsearch in a terminal works

Thomas W.

14:07

@A.B. Probably have to configure it accordingly, I doubt it default knows how to be configured and use correct data

(most LDAP auth systems are like that)

A.B.

Yes, I have the plugins configured

SSL, anonymous access, Base DN and so on

The interesting thing is, I can use port 636 and SSL in Thunderbird Address Book, but not with ldapsearch in a terminal on the same machine.

Thomas W.

is LDAP listening on 0.0.0.0 or is it only listening on the IP address on one of the NICs?

because if it's not listening on 0.0.0.0 and/or 127.0.0.1 it's not listening on localhost, so...

that could be one issue

Serg

14:45

@ThomasW. about your bounty question. I doubt it is actually possible to disallow an interface to be used by network manager, because it has to be somehow connected to the router in the first place, to get interwebs access to the VM. . .however, you might want to look into a firewall option; for instance for a moment block your host interface to disallow all traffic on that interface, but allow traffic on your VM adapter . . . .Also,with virtual box in the settings you can specify specifically

which bridged adapter to use

Thomas W.

@Serg Except it's not VBox. And the adapter won't work with the Kali VM via "Bridged"

hence why i'm trying to figure out if there's a way to 'enforce' network manager to not try and control it. Theoretically, /etc/network/interfaces entry for the wifi adapter (its name is defined statically in udev rules already) might work, but... not sure

and meh, i have the rep to waste if nobody can provide an answer.

Serg

@ThomasW. I was using VBox as a mere example, but you might wanna specify which VM you are using. At least it might give people a hint

As far I was seeing from my googling and stack site hopping, it seems like you cannot whitelist a specific program to be used by interface, but only ports ( iptables hint )

Thomas W.

@Serg meh, worst case is just make it 'manually' configured via /etc/network/interfaces... that way NetworkManager won't touch it
