Ask Ubuntu General Room

Imagine this. A smart hacker knows people use this leetspeak method, and it's a simple substitution, @Windows3.1. They then test chocolateicecream and do a leetspeak substitution.

Windows 3.1

@KazWolfe how about get persian keyboard and type English word with keys. it will be like "lkjalsdjfldsjfglhofeadsfdsl;j" in Persian

Kaz Wolfe

@Windows3.1 And a smart hacker thinks "hey, people use different keyboard layouts! I'll swap them around and see what happens!"

Any password derived from simple english words is NO MORE SECURE than just using the basic english words!

Windows 3.1

3:06 AM

@KazWolfe EVERYONE knows that 99% of everyone's passwords are either like "chocolateicecream" or "9323"

that's the world today. either a word string or 4 numbers.

Kaz Wolfe

And smart hackers will test substitution methods.

Leetspeak being one of those.

Windows 3.1

so,

Kaz Wolfe

Your example ((|-|0(0|@73!(3(|^\3@/\/`) is no more secure than the seed, chocolateicecream` because it's a predictable substitution scheme.

Windows 3.1

@KazWolfe but PERSIAN? that is not a widely used language. And only about 1% of the people use that. Hackers do better looking for numbers and letters.

@KazWolfe you miss the piont!

Kaz Wolfe

@Windows3.1 I'm missing no point.

Windows 3.1

3:08 AM

@KazWolfe look. only 1% of the people use substitutions to THAT LEVEL

Kaz Wolfe

So you're using numbers to be secure?

Windows 3.1

most of the substitutions people use are more like "ch0c01@t31c3cr3@m"

that password is not secure

Kaz Wolfe

okay, and they get caught pretty fast.

Windows 3.1

yeah

Kaz Wolfe

But yours is NO BETTER!

It's still a simple substitution cipher!

Windows 3.1

3:09 AM

YES IT IS!

Only 1% of the people use that!!!

Kaz Wolfe

If I'm a evil hacker, all I need to do is add that substitution method to my script.

Boom, cracked, gone.

Also if you think a password is secure because nobody uses that method... that's a really bad idea.

Windows 3.1

@KazWolfe should I be like half of the population and make my pass "1234" or maybe even something like "2624"?

Kaz Wolfe

No.

Windows 3.1

the rest would be something like.

Kaz Wolfe

You should use random passwords.

Windows 3.1

3:11 AM

"babyjohn"

"Hannah"

Patriots2005"

Mateo

bet only one person uses that one...

Windows 3.1

"Redsox2004"

"DonaldTrump2016"

those types

Mateo

doesn't make it more secure ;p

Kaz Wolfe

n9I7dbaV1#yB@64^

That is a secure password.

Windows 3.1

dude that is what the hackers are looking for!

WHO WILL REMEMBER THAT PASSWORD?????

Kaz Wolfe

3:12 AM

NOBODY

THAT'S THE POINT

Windows 3.1

then NO!!!!!!!!!!!!

WHAT'S YOUR LOGIN PASSWORD?

Serg

NTU2YWY0ZGQwNzVkNmUyNThhNDhmYzQyN2QxNDIwMDIwMmI3ZGY0YyAgLQo

Kaz Wolfe

Something simple and easy to remember (and crack)

Serg

THat ^

Kaz Wolfe

Because it grants me access to absolutely nothing of importance.

Everything important is secure behind a much stronger password.

4

Windows 3.1

3:13 AM

@Serg so, if your login pass looks like that, how do you log in? you either remember it or have it written down

I am talking about UAC login

Serg

@Windows3.1 or you know how to "generate" it >:)

Windows 3.1

all people need to remote access you with remmina

Kaz Wolfe

Actually, @Windows3.1, my drive encryption password is a quote from a book.

Windows 3.1

@serg FINE SO YOU GENERATE IT!!!!

Mateo

yeah, the keys are like a whole page of random text ;)

Kaz Wolfe

3:14 AM

Over 140 characters long.

I don't care.

I remember it, and it's secure. And it has a LOT of entropy.

Windows 3.1

gah sorry @Mateo

@KazWolfe not necessary

Serg

It really depends on the data. If that data is important, it better have strong,long,random password

Kaz Wolfe

@Windows3.1 It is overkill, but it works very well for me.

Serg

for which you don't have to rely on memory

Kaz Wolfe

And because I have to remember it, and it's vulnerable to a dictionary attack, I make it really long to make such a dictionary attack very hard.

edwinksl

3:16 AM

@KazWolfe which password manager do you use

Kaz Wolfe

LastPass.

edwinksl

ok

Zacharee1

@KazWolfe just make your password a random tweet every day

Kaz Wolfe

With KeePass local for secure things.

Windows 3.1

and if someone actually uses a ︻̷┻̿═━一 on you, you should hope you remember it lol. wont help to not.

Zacharee1

3:16 AM

a what

Windows 3.1

@Zacharee1 isn't it past bedtime for you

Kaz Wolfe

3:17 AM

actually it does help.

edwinksl

@Zacharee1 go clear the damn review queues

Zacharee1

@edwinksl shouldn't the MIT student be asleep too though?

Kaz Wolfe

I can be beaten to an inch of my life, and I will be unable to give away any passwords.

My system is rubber-hose resistant.

edwinksl

@Zacharee1 some claim i don't sleep

Windows 3.1

@KazWolfe if you remember it you can lie and say you don't. if you dont remember it they will think you are lying

but really.. there's no reason why you shouldnt remember a pass.

Mateo

3:18 AM

@Windows3.1 Unicode has one of those 🔫

Kaz Wolfe

@Windows3.1 And if I do remember it (I do), and I give it to them (I will), and they use it (they will), they won't have access to anything at all.

edwinksl

@KazWolfe nice, i thought you might be using something different that i haven't heard before

Windows 3.1

@Mateo could get you flagged on the internet

Kaz Wolfe

Because my system requires TPM and a physical key

Mateo

I could still custom flag your message ;P but I didn't

Windows 3.1

3:19 AM

LOL

I'm talking about an NSA flag

Kaz Wolfe

moo

We're all flagged by the NSA already because we use Linux.

8

Windows 3.1

if you live in some countries including dumbass USA

@KazWolfe yeah probably

Mateo

linuxjournal.com/content/…

Windows 3.1

@KazWolfe HEY :P

worse flag tho

Kaz Wolfe

I consolidated the post such that it makes sense without context.

Windows 3.1

3:21 AM

infoworld.com/article/2832337/…

Kaz Wolfe

Either way, @Windows3.1, a random password is way more secure because I can't remember it, meaning it has no dictionary entry ever, and it's protected by a lot of layers.

And random passwords have a metric ton of entropy.

Serg

ok, so OP wants exactly what my script does. Gotta polish it and post

Windows 3.1

how about one big long KJV Bible verse lol

Kaz Wolfe

@Serg what script?

:-)

David Cole - Grammar Police

Idk if you'd know anything about this, but any idea why after running sudo ip link set dev eth0 down my eth0 connection would go down then IMMEDIATELY come back up?

Kaz Wolfe

Do you have a script in ifdown that brings it back up?

David Cole - Grammar Police

Nope

Wait

how would I check that

Serg

3:24 AM

@KazWolfe oh, there's a question which asks to bring back single click expo. Back in 12.04 apparently if you click on a single window icon in launcher, it would open window spread. Now in 16.04 it only works if the icon references multiple windows.

so i wrote a script to simulate the old functionality

Kaz Wolfe

@Serg oh i thought you meant the bash thing. because that would make me sad.

Serg

@KazWolfe what bash thing ?

the timer ?

Kaz Wolfe

@Serg remember the "open new tab in gnome terminal" question?

the one where you wrote a script and I wrote a bunch of one-liners?

@DavidCole-GrammarPolice what happens if you just use ifdown eth0?

Serg

@KazWolfe yeah, i remember. OP has issues with xdotool, iirc

3:28 AM

k it's "ntoskrnl64"

try to use it without being me = system reboots, TPM is wiped, can't login.

Windows 3.1

@KazWolfe gah I dont have your ip :|

Kaz Wolfe

or even boot for that matter lol

Windows 3.1

wish stack exchange was a regular forum with BBcode. I could easily hack you

easily

or HTML

Kaz Wolfe

k my IP is 127.33.252.70

go wild

Nathan Osman

...and that's why no smart people use those forums anymore.

@KazWolfe Fires LOIC...

j/k

edwinksl

3:30 AM

@NathanOsman the implications

Kaz Wolfe

if you'd just use bbcode to get a list of IPs through a malicious image, you can still do it here

Zacharee1

@NathanOsman if I don't know what a forum is, do I qualify as a genius?

Serg

aint no smart person uses LOIC

Kaz Wolfe

i use loic

Nathan Osman

Ergo...

Kaz Wolfe

3:31 AM

mostly to kick the Roku off the network.

Nathan Osman

Lol. That is a little bit funny.

Kaz Wolfe

eh, my router can handle it.

i LOIC and the load spikes to a whopping 0.27!

Nathan Osman

Lucky you - I don't even have telnet access to my router.

one word: ssh

Kaz Wolfe

i love my router ACP so much.

Zacharee1

@Serg you ssh

@KazWolfe I thought you weren't allowed to access it?

or is the modem separate?

Kaz Wolfe

the modem is what i can't hit

Nice! ASUS router. :)

I love my LInksys WRT1900AC. Too bad its CPU isn't as fast as the WRT1200AC is though.

Journeyman Geek

I'm toying with throwing pfsense on a NUC class machine ._.

Kaz Wolfe

3:45 AM

@NathanOsman are you using an IPv6 tunnel?

Nathan Osman

Nope - I have full IPv6 access from my ISP.

And it's set to pass-through in the router.

Kaz Wolfe

is your isp being sneaky with an IPv6 tunnel?

Nathan Osman

What difference would that make to my router?

Kaz Wolfe

they're really tunneling but saying it's native

Nathan Osman

I can connect directly to my PC from another server over IPv6.

Kaz Wolfe

3:47 AM

as can i thru my tunnel

Nathan Osman

But let's try a transfer from my NAS and see what the CPU does.

Hi all :D

\.o

IPv6 doesn't work with my carrier and my router. :(

Nathan Osman

3:48 AM

Doesn't do a thing, though the transfer sticks at 30 MB/s.

@JourneymanGeek Is that article mode ?

@NathanOsman I think a lot of routers now have dual-core CPUs in them. Is the one your accessing WRT ready?

Journeyman Geek

@SeverusTux no

Severus Tux

@JourneymanGeek I had imagined lot worse, It looks good.

@SeverusTux I personally find it really useless, other than a few small things ;p

It's missing a lot of the more familiar Unix utilities.

I can't find watch, for example.

Kaz Wolfe

does it have vi?

Nathan Osman

Yes, indeed.

Kaz Wolfe

I prefer Calibre solution. Debian Calibre package come with ebook-convert utility. Grab HTML files from site by: $ wget -r -np -nc -k -c http://.../.../.. Locate your main HTML file (usually book.html or index.html) and convert to MOBI: $ cd dir-with-index $ ebook-convert index.html book.mob...

Kaz Wolfe

implemented what?

Journeyman Geek

calibre is the hotness if you don't use the gui

Not sure if that will work exactly but its worth a try

Serg

@KazWolfe gnome-terminal generates two signals that window stack has changed. All other windows give just one

It's a Gnome app.

I'm afraid my expectations for anything Gnome are... quite low.

IanC

Terrance

I don't think I have used terminator enough to have an opinion of that yet.

Serg

Meh, it crashes sometimes on me. That's a downside of a terminal app written in python - garbage collection

Terrance

4:33 AM

Ah, good to know.

Serg

that is . . .if you keep that terminal window open for hours and hours

Terrance

I keep mine open forever. Part of my job I leave terminals open all the time.

Serg

but split functionality is cool

Maybe it's just me

Terrance

I really do like the urxvt in conjunction with CSSH at work so I can open multiple servers at the same time and work on them.

Serg

is CSSH similar to screen ?

@IanC how was the double shift ?

Terrance

4:36 AM

Cluster SSH

I open 8 terminals at a time with it right now. I could go more.

IanC

it was alright, 12 hours seems long but we ended up doing less work than I expected @Serg

Terrance

But I like using the urxvt terminal because my keepalive script I use sends a space / backspace every so often to each of those terminals because especially with Dell servers their BMCs tend to timeout about every 60 seconds

IanC

It was a great day actually, I surfed in the morning, almost got late for work but ended up getting there just in time, and had this double shift, which is a little extra in the paycheck later :)

Welcome to the OP3 club.

I hope you have a small hand :P

Kaz Wolfe

First off, I don't get cell service here, so no wifi calling.
Second, I can't get mobile pay because root/custom firmware ;-;

those are the only two things that are potentially holding me back from buying a OP3 now and selling my iPhone whenever.

actually, safetynet was a horrible move against FOSS

Nathan Osman

@KazWolfe Forget that then.

Kaz Wolfe

How do you guys differentiate b/w lowercase " L (l)" and uppercase "i (I)" ? I thought "lmao" -> "In My Arrogant Opinion" and now my roommate says its "Laughing My Ass Off".

when someone says it

ELL EM EH OH

@SeverusTux I'm afraid it's the latter, and no, there is no way to discern between lowercase "L" and capital "I" in a number of sans-serif fonts.

It would have helped tremendously if people would properly capitalize initialisms.
