Q: SSH does not respond only from Ubuntu

We have several desktops in which both Windows and Ubuntu are installed. But, some of them cannot connect to some servers only from Ubuntu. Here are the summary of the current status: Cannot connect to the servers from Ubunutu (14.04, 16.04) If username/password is wrong, it gives "Permissio...

@ThomasWard could you please delete some of the chat messages that have mine , Nathan's and IanC's utox ids ?

Link chat.stackexchange.com/transcript/201?m=31526708#31526708

Other people's ids should be around the same time mine is posted

Thank you in advance

Byte Commander

00:09

Nathan is a mod himself, he could have deleted it if he wanted. Just FYI :)

Kaz Wolfe

why are tox ids so secret?

Seth

they're only as secret as your email or jabber

I deleted @Serg's. I don't see one from @IanC. I'll let @NathanOsman delete his if he feels it necessary.

Nathan Osman

What is this?

I don't care if anyone has mine.

Byte Commander

@KazWolfe Actually they are even less secret than your email.

They contain a NoSpam code. You may change it to make friend requests over that old ID impossible, but it still works for your old contacts.

Seth

oh that's neat

Byte Commander

00:19

Yeah, it's the last few bytes (9 or so?) of your ID.

They are only necessary for friend requests, but not for staying in contact.

@NathanOsman

You've worked hard. This one is easy, you deserve it. Welcome to level four.

Deep within a tree, three brothers sit. In which order must they be hit?

Serg

tree . . .binary tree maybe, root, and two branches. If I remember correctly there's 3 ways: preorder, in-order, and post-order traversal for trees

@KazWolfe

Kaz Wolfe

um...

huh.

now i'm actually confused

because i don't think it's literal -- it's a hidden message

hexdumps show nothing of interest, so it's not unicode substitution

@NathanOsman Once we solve this, we should post them all to Puzzling

Nathan Osman

01:06

Yeah.

I'm mobile now.

So my interaction will be limited.

Serg

@KazWolfe can you add me back to the group ? I had to reload my tox

Nathan Osman

I also have a new ID for mobile.

Let me get on my lappy

Any ideas for part 4?

Nathan Osman

I can't read it all.

Kaz Wolfe

Huh?

Nathan Osman

Mobile chat is cutting it off.

Kaz Wolfe

How many lines can you see?

Serg

@NathanOsman Deep within a tree, three brothers sit. In which order must they be hit?

The quote formating was cropping it out for me too, but normal message is never cropped, so here you go

Nathan Osman

01:36

Thanks.

What is deep within a tree?

Trunk? Cave?

What's a story with three brothers?

Kaz Wolfe

I don't think it's a riddle

There's something hidden in there.

Serg

trees have those circles and layers

Nathan Osman

Wasn't there a 3x3 grid?

What was on the home page again?

Serg

@KazWolfe 3 brother story from harry potter, family tree here: harrypotter.wikia.com/wiki/Peverell_family

Nathan Osman

See... it is a riddle :D

Kaz Wolfe

01:48

Let's see. That is Antioch, Cadmus, and Ignotus

IanC

man, the dudes from Code Golf are crazy

I tried one challenge, got my heard working to make an alphabet wave with the least code on C. Managed to do it with 86 bytes, not including the main() function

Nathan Osman

@KazWolfe is that the order?

IanC

         for(int c=-11,n=-26;++n<1;){while(c++){printf("%c%c",90+n,n?91+n:65);}c=-11;puts("");}

Kaz Wolfe

@NathanOsman Order of birth and death.

but what do we have what shows it's Harry Potter?

IanC

then a guy does it with 60 bytes (including main!) with some crazy hack!

          main(i){for(;i<703;)putchar(i++%27?65+(i/27+i%27%2)%26:10);}

Nathan Osman

01:52

@KazWolfe toast? :D

IanC

that module trick was really cool, I can't even imagine how he figured it out

Kaz Wolfe

@NathanOsman The thing on the homepage was:

N O P
O P Q
P Q R

i mean, the peverell thing might work, but it's a leap of logic

Serg

@IanC basically while loop using for loop, and putchar. printf must have format string as arguments, putchar apparently doesn't

also looks like he uses ternary operator

Kaz Wolfe

are there any other ideas?

look at the spacing inconsistencies though

not every "bit" or whatever is separated by just one space

mod pin abuse

Serg

@KazWolfe that link seems to fit

Nathan Osman

I didn't do it. Lol.

I have more keybase.io invites BTW.

IanC

@Serg the impressive part isn't the for, it's the logic behind the selection of the ASCII value. He makes a modulus of i++ with 27, the value will increase from 0 to 26 and then go back to 0 again continuosly. If the modulus value is not 0, putchar will print the ASCII value of 65+i/27(which will be constant for 26 iterations and then increase by 1) + i%27(1 through 26)%2(oscilates between 1 and 0. This accomplishes the alternating effect)

@Serg The last %26 modulus just keeps the value of whats inside (i/27 + i%27%2) EXCEPT when it reaches 26 (to make sure Z will alternate with A instead of the next ASCII code)

Serg

02:36

it's all number magic :)

and some people are magicians

IanC

the :10 is just a newline for when 27 numbers have been printed

man, it's crazy how someone can come up with this

but I"ve seem some crazy codes on code golf

just wonder which is faster, to use modulus for those iterations or conditionals (in case we are not worried about code size anymore)

well, it was a productive day, could get my studies going, but I gotta wake in less than 6 hours to work

and I plan on surfing tomorrow, so better get some rest

good night!

Serg

03:04

damn flies

i cant stand it - every time i have some sort of food in my room , they show up

Kaz Wolfe

so.

@NathanOsman, any idea on the morse puzzle

so, splitting on double spaces returns this: cu c dak o b ugpyd p cy co xf oyabecbi rb yd odrgne po ru

Nathan Osman

No ideas yet.

Kaz Wolfe

03:19

okay this can't be a coincidence

this is the hex, provided . = 0, - = 1

a3 51 be 0e 6b 8d 57 5e 4b db 0a 81 45 cf 16 8d d1

actually it is. there are just enough bits to form coherent hex bytes

ƎpᴉʇʎXD

I laughed so hard today that I fainted

Kaz Wolfe

oh?

ƎpᴉʇʎXD

I woke up 20 min ago

Kaz Wolfe

@ƎpᴉʇʎXD want a challenge?

ƎpᴉʇʎXD

no

Kaz Wolfe

03:33

@NathanOsman the spacing doesn't seem to be relevant, really.

ƎpᴉʇʎXD

if the chellenge causes me to faint you will be the cause

Kaz Wolfe

this is actually strange. i can cleanly divide the text in quite a few ways

and my head hurts

ƎpᴉʇʎXD

me too

Kaz Wolfe

a lot happened

Nathan Osman

@KazWolfe I'll probably have to call it a night. We might need to ask this one on Puzzles.SE.

Kaz Wolfe

03:45

i'll look at this more tonight and tomorrow

Serg

how's it going guys ?

Kaz Wolfe

i'm sure it's simple once we realize it

@Serg I got part 5 and my head hurts for more than one reason now

Serg

@KazWolfe what's in part 5 ?

Kaz Wolfe

unless those are just random

i wish we got a bit more instruction but eh

Serg

Kaz Wolfe

tell me what it finds, if anything

Serg

@KazWolfe oops, script got killed , too many combos , i guess

ƎpᴉʇʎXD

03:59

python to the rescue

Kaz Wolfe

hmmmm... there has to be something we're overlooking that's really easy

unless it's NOT morse, this is some cipher.

Serg

got something better , running

DODGE

there's that

Kaz Wolfe

this is either a non 1-1 cipher or this is not morse

Serg

@KazWolfe I assume you guys tried the morsecode.scphillips.com/translator.html It has feature to play out the code. Does the sound remind you of any song ?

Kaz Wolfe

i did not

and no, it does not remind me of a song

though i'm not too good with music

Serg

04:09

maybe @ByteCommander or @NathanOsman could recognize it ^

Kaz Wolfe

is it a real song?

Serg

slowing down to 15 wpm makes it sound like a tune. I mean, it does have a lot of repeating parts, kind of like some form of beat, but i can't be sure

probably just my imagination

hmmm , my script already generated 4.8 GB file . . . . too many possible combinations

ƎpᴉʇʎXD

I managed to break Ubuntu by inserting my SeaGate...

It couldn't handle the DLL files and crashed

Serg

i probably should have filtered the combinations to print out only those that have actual words in them
