Ok

user136984

@ByteCommander: Why is qTox making contact with known botnet servers?

user136984

I thought it was a P2P thing and wouldn't be connecting to any central servers. Well, not so many anyway, with such bad reputations.

muru

@kos thanks for the effort, anyway!

Seth

How's Vi and Vim going @muru?

muru

@Seth 2-3 questions per day. Not much work for mods.

RPi Awesomeness

16:05

@muru :(

muru

Dunno how to drive traffic. :(

Seth

Yeah, that's kind of a harder subject to drive traffic for. I wish I had more time to hang around.

muru

And most q's are beyond me. When I do finally manage to answer one, Carpetsmoker does a Gilles on me. :D

Seth

Sounds like it might be a question for Community Building @muru :p

user136984

@ByteCommander: It is communicating with them using UDP-UNKNOWN, which if it was just UDP, would not be too uncommon, but UDP-UNKNOWN traffic is likely to be malicious, especially if it is talking with a botnet server. So I am just wondering if there is a legitimate reason for it to be engaging in such activity.

user136984

16:07

Although, if it is really meant to be talking to all those servers, then it could just be by chance that some of them are infected and blacklisted for it.

Seth

@muru lol

muru

Interesting site. I'll browse through it. :)

RPi Awesomeness

Grr....I don't want to have to include all those lines of filter_SOANDSO.add_pattern('*.EXTENSION') but my

with open('data/imglist', 'r') as imgList:
    for img in imgList:
        filter_img.add_pattern("*."+img)

isn't working :P

There. Formatting. Gosh.

kos

@muru Np, anyway if you eventually find a way around this and you remember ping me do so, I'm interested as well

RPi Awesomeness

And I don't know why. No errors are being returned, the filter just isn't working :P

Seth

16:13

throw a space between the plus sign and image. I doubt that's the issue but it's bugging me ;)

@RPiAwesomeness This is where print is your friend. Throw some print statements around. Print imgList once you open it, then print img for every iteration.

Got all the data you expected?

I'm not familiar with the filter idea but try to print the filters too.

RPi Awesomeness

@Seth I believe so. I've tried that, and I get this:

Seth

we'll you're going to have to tell me if that's the expected output.

RPi Awesomeness

Dunno why it's not being accepted by the add_filter() function...

Darth_Vader

when using perl with substitute what is the proper way to write perl -pe 's:\r^{:foo:g' I can get it to work without \r but Im having trouble finding what I can use.

RPi Awesomeness

That should be what comes out AFAIK.

Seth

16:16

did you add that space?

RPi Awesomeness

No, that's the weird thing. I can't figure out why that's there. I've tried strip('\n') but that hasn't done anything.

Seth

@Darth_Vader We've got a few perl/regex experts around but I'm not sure they're active right now. Have you considered asking a question on the main site? Chat is fine but you might actually get the answer faster on the main site :)

@RPiAwesomeness I meant in your code.. Add a space between the " and the + as well as after.

Darth_Vader

yes I was going to ask but before I ask I was curious if someone knew of a source to reference

RPi Awesomeness

@Seth Oh, yes.

Seth

Is that a yes I added it yes?

RPi Awesomeness

16:18

I think there's a \n or something hiding in there.

Seth

@Darth_Vader That's perfectly fine.

@RPiAwesomeness this is kind of hard to debug over chat ;p

Darth_Vader

ill ask the main site and see

RPi Awesomeness

@Seth Yes, I added it.

@Seth It is :P

Seth

seems like you're getting the output you expected? Besides the newlines anyway.

RPi Awesomeness

Yeah...

Seth

16:20

You sure about filter_img?

Make sure you print the pattern to, just to make sure it is what you expect.

Concatenating strings can be weird sometimes.

RPi Awesomeness

Yup, the pattern is coming out correctly. Perhaps there really is a newline hidden in there that's screwing things up...

Seth

Try print(repr(pattern).

RPi Awesomeness

AHA!

There IS a \n in there!

Seth

How'd you find it?

Serg

hey guys, can i haz a question about awk ?

RPi Awesomeness

16:27

@Serg that print(repr(pattern)) command

but then why doesn't pattern.strip('\n') work?

Serg

@RPiAwesomeness wrong person ^_^

RPi Awesomeness

\o/ wooo!

Figured it out.

I needed to strip('\n') the variable, not the concatenated string.

kos

@Serg If it's about the pattern I might help, but for the rest I don't know awk

Serg

nah, I think I just found it. I need to awk something from multiple files, replace, and store it back in. It's a for loop

Q: How to replace a string on the 5th line of multiple text files?

I want to replace the 5th line of multiple text files (file1.txt,file2.txt,file3.txt,file4.txt) with the string " Good Morning " using a single terminal command. All the text files are located on my ~/Desktop. Note: My desktop consists of 6 .txt files.I want to apply the change to above mention...

something for f in /path/to/files/*; do

now how about cat stuff into multiple files?

RPi Awesomeness

... or not?

Yup! We're good!

Yay!

Serg

16:33

got it: cat testerfile | tee tester{1,2,3,4}

kos

@Serg Anyway there are awk solutions in both answers

@Serg Also it looks like from coreutils 4.10 you can use use awk in-place

blade19899

Where does someone go If he/she want to start learning Python.

Wana create an app!

Serg

@blade19899 ask Jacob Vjim =D

that guys does everything in python

RPi Awesomeness

@blade19899 Code.org is pretty good if you want online. Otherwise, try the Head First Python book. That book is one of the best I've used that gets you going on Python basics quick.

blade19899

@RPiAwesomeness Downloaded the Head First Python book! I'm going to play with it for a bit! Thanks!

@Serg Thats the creator of Python right?

RPi Awesomeness

16:40

@blade19899 np :) I assume you bought it from their site as an e-book?

'cause last I checked, it wasn't free.

blade19899

@RPiAwesomeness You can download it from here for free or an option to buy it: it-ebooks.info/book/373

@RPiAwesomeness ?

Could you check that link for me and the pdf it provided!

RPi Awesomeness

@blade19899 ... not so sure if that site is entirely legit...

blade19899

@RPiAwesomeness The pdf seems legit!

RPi Awesomeness

Can you send me a screenshot or two?

I mean, the PDF might be the real book, but I don't know if that site is legal or not.

blade19899

@RPiAwesomeness You can just download the pdf?

RPi Awesomeness

16:45

I've got slow internet :P

kos

Also, a free good ebook on bash?

RPi Awesomeness

30 MB is gonna take at least 10 minutes to download

Serg

@blade19899 Nope, that's a guy is one of the users here

@blade19899 like I said, he does all the scripting in python. He's really awesum

blade19899

RPi Awesomeness

@blade19899 Yeah...I'll look at the PDF once it finishes, but I personally wouldn't use that site. I'm usually wary of sites that end in .info and especially since they seem to be offering a free copy of a book that usually costs ~$30.

blade19899

16:47

RPi Awesomeness

@blade19899 Yeah...that looks like the full book. Can you read all of the pages?

blade19899

@RPiAwesomeness 445 pages long

RPi Awesomeness

@blade19899 Yeah. Most likely that site isn't legit. However, it's up to you what you're gonna do.

blade19899

Virus total says its clean. First uploaded 2012

Darth_Vader

@blade19899 and?? a great book is sometimes 1200+ pages long.. how much you trying to get out of it?

blade19899

16:50

I'm just a guy trying to learn python and I want to learn it the right, standardized proven to work way.

Darth_Vader

well by your comment I dont see that, it looked like you were looking for the cliff note version of python.

blade19899

> This PDF file contains 2 JavaScript blocks. Malicious PDF documents often contain JavaScript to exploit JavaScript vulnerabilities and/or to execute heap sprays. Please note you can also find JavaScript in PDFs without malicious intent.

RPi Awesomeness

@blade19899 Well, that book is a very good way to start. However, I fear that the site you got it from isn't legal. Again, it's your call.

blade19899

> The combination of automatic actions and JavaScript makes this PDF document suspicious.

@RPiAwesomeness Yeah not using this any longer... deleted

RPi Awesomeness

@blade19899 Do you have a local library?

blade19899

16:53

@Darth_Vader I don't know jack about python, knowing the cliff note, and then the rest, is how I want to learn it. Just in case I find it way to complicated???

@RPiAwesomeness Local? as in around my area? No. I life around farms...

RPi Awesomeness

@blade19899 Ah

amazon.com/Beginning-Python-Using-2-6-3-1/dp/0470414634/…

Is another good one. Might be worth buying.

blade19899

@RPiAwesomeness I will look in to it! Thanks!

RPi Awesomeness

@blade19899 :)

Darth_Vader

@RPiAwesomeness very good books

Seth

@RPiAwesomeness yay

1. Whetting Your Appetite - Python 3.4.3 documentation

Seth

There's also interactivepython.org/courselib/static/thinkcspy/index.html and learnpythonthehardway.org @blade19899.

Plus the official docs are great!

Oh and code academy. codecademy.com/tracks/python

which is ok

learnpython.org and python.org/about/gettingstarted

blade19899

@Seth You sir, are awesome.

Seth

and if you like to dive right in: learnxinyminutes.com/docs/python

@blade19899 :)

RPi Awesomeness

@Seth Oh yeah. I forgot about all of those.

Seth

I'm pretty well versed with some of them, not having much money for expensive programming books ;P

Fabby

17:10

@A.B. That exists! ignore user script

Seth

Although I do live near an amazing library, CS books aren't their speciality.

RPi Awesomeness

@Seth Boo. They don't have a version of C++ in English :(

Oh wait...

facepalm

those are the translations :P

Seth

learnxinyminutes.com/docs/c++ ?

RPi Awesomeness

@Seth I didn't realize the titles on the left were selectable and that the buttons on the right were just translations :P

Seth

also @RPiAwesomeness: c.learncodethehardway.org

RPi Awesomeness

17:11

@Seth But that's C. I want to learn C++

Fabby

@A.B. (and an upvote for you removing the "parasite" comment.)

RPi Awesomeness

Also. It is bloody beautiful outside today. I might just have to go work outside...

Seth

sorry for teh pings

RPi Awesomeness

@Seth lol, It's fine. I didn't even have my earbuds in :)

Fabby

(I've already upvoted, so will not check whether you did or not, but you're better then him and someone else will find this useful as well and upvote too!)

RPi Awesomeness

\\o \o\ \o/ /o/ o//

Is the proper stickman dancing wave.

Darth_Vader

proper stickman is holding a beer but they havent implemented that one yet

RPi Awesomeness

Oh, yes. Of course.

I think they chose not to implement that one because he's still underage.

GitHub has been updated. Now, to implement multiple attachments (won't be too complicated ... in theory)

Then, it's on to a basic GUI.

[ SmokeDetector ] Offensive answer detected: Command not found -> did you mean -> Yes! by devnall on askubuntu.com

Nathan Osman

O... kay.

Why anyone would name their project with that word is beyond me.

Not terribly professional.

Any mods care to comment on what to do with that one? :P

A.B.

@Fabby removed :)

RPi Awesomeness

@NathanOsman ... ikr. Goodness.

Mateo

@NathanOsman well, we have had other ones like that before brain**** the programing language, and get****done the script, those are the only swear word posts I haven't flagged and should be the only ones that stay

so, that sounds similar...

RPi Awesomeness

It's still a fairly offensive name. Brain**** isn't a terribly common language and I'd never even heard of that other one, I fail to see why people even include swear words in the names of these things anyways - it's unprofessional like @NathanOsman said :P

Mateo

17:54

yeah... It's had quite a bit of history on stackoverflow :/

RPi Awesomeness

Here, yes.

Otherwise...it's rather useless :P

Nathan Osman

The language itself is nearly useless.

The code appears heavily obfuscated and has very limited capabilities.

Perl can appear obfuscated as well, but has some practical value.

RPi Awesomeness

@NathanOsman Exactly. That's why it's called Brain ****

Nathan Osman

Right.

RPi Awesomeness

Cool! Formatting worked out correctly for once :D

Serg

18:08

question: I have this script here

#!/bin/bash
set -x
for file in /etc/NetworkManager/system-connections/* ; do
grep 'dns=208.67.220.220;' "$file" || ( awk '{print;if ($1=="[ipv4]"){getline; print "method=auto\ndns=208.67.220.
220;\nignore-auto-dns=true"}}' "$file" > .tempfile && mv .tempfile "$file" );
done

Which is supposed to be adding dns and ignore-auto-dns lines to system-connections

but every time I run it, the connection breaks, and nmcli con list doesn't see any, even though files seems correct

script seems fine, but connections still break

RPi Awesomeness

Oh good gravy. BASH...

Serg

well, technically i am using mksh, but just bash here, for 90% of the other users

I just can't put my finger on what I am doing wrong

if I edit a file in /etc/NetworkManager/system-connections/ with nano, it's fine; but with this script - everything breaks

@ByteCommander 'cause consoles :D

ByteCommander

18:24

It's a long essay, but worth reading. And funny :)

RPi Awesomeness

@ByteCommander I think I've actually seen this before, yeah it's good

Nathan Osman

@RPiAwesomeness Didn't he just come out with a remix album?

ByteCommander

Back to matrices... Have to hold a presentation tomorrow. :P

RPi Awesomeness

@NathanOsman Yeah, do you follow his music?

'Yes, give me the office of the President of the United States.... NO, I WILL NOT HOLD. This is an emergency.... Hello, Mister President, I'm afraid I have some bad news. I've just been informed that The Internet is not working.'

Nathan Osman

Yeah, I have Google Play all access, so in theory I have all of his music :)

RPi Awesomeness

18:26

Best quote from that article :D

@NathanOsman Ah :)

I'm really hoping he's coming near me on his thissinotatest tour. He's gonna have Britt Nicole and Colton Dixon as guest stars :D

Nathan Osman

He's coming here in August, I think.

RPi Awesomeness

O.O

good gosh

@NathanOsman Lucky :D

"Using an OS used to be hard work. When things went wrong you had to dive in and get dirty to fix things. You learned about file systems and registry settings and drivers for your hardware. Not any more."

Exactly why systems like Linux are so great :D

"When they hit eleven, give them a plaintext file with ten-thousand WPA2 keys and tell them that the real one is in there somewhere. See how quickly they discover Python or Bash then."

Sneaky...

Nathan Osman

WPA2 can be cracked?

RPi Awesomeness

@NathanOsman No, they have to go through that file and try to find the correct key so they can connect to the WiFi :)

ByteCommander

@NathanOsman Brute force only, I thought...

@ByteCommander: Did you see my earlier pings? :)

ByteCommander

@ParanoidPanda what pings?

I don't think so...

user136984

I pinged you about qTox and something odd.

user136984

@ByteCommander: I send you a few messages here.

user136984

:)

Fabby

@A.B. Danke! (Still not checking, having confidence that you did!) ;-)

ByteCommander

18:44

@ParanoidPanda No idea about that. @Fabby to the rescue please! ;)

A.B.

Bitte und thank you for the confidence =)

ByteCommander

Paranoid alert...

And @ParanoidPanda RTFM of the Tox core!

Fabby

reading

ByteCommander

back to school work...

Fabby

@ParanoidPanda Because it's super-secure so botnet herders are using it too???

(If I was a botnet herder, that's what I would use)

user136984

18:46

@Fabby But why would my machine be talking to the botnet servers?

Fabby

@ParanoidPanda :D

Now I know what you're so paranoid!

user136984

I thought it would only have a P2P connection from my machine to my contacts.

Fabby

YOU'RE A BOTNET HERDER!

:D:D:D

user136984

:D

user136984

That would be nice, perhaps...

user136984

18:47

But sadly no... So what is this traffic?

Fabby

I dunno, didn RTWFM yet...

user136984

Is someone controlling a botnet from my machine?

user136984

:D

user136984

That would be funny!

user136984

Where is the manual?

Fabby

18:48

WITFM? TITFM!

A.B.

@Fabby Where is your question of how to view installed packages from a given period?

The perl script

user136984

@Fabby Sorry, no idea what those stand for... :P :D

Fabby

@A.B. Huh?

A.B.

Either I'm blind or stupid or both.

user136984

But at least I got the manual now... :D

Fabby

Serg

19:23

hey guys

plz review my answer here: askubuntu.com/questions/466045/global-dns-change/615951#615951

Thomas W.

@Serg Cursory glance: why did you keep the original answer?

the one you've edited in is radically different

Serg

Because the original also works. i use it on two of my laptops and it's IMHO best way.

And I just like keeping history of things . . .

Thomas W.

well the edit logs keep a history btw :P

Fabby

@Serg KISS!

Keep It Simple & Stupid...

Keep the simplest of your answers... (IMHO, the first one)

This is a purely personal and subjective opinion, feel free to disregard completely!

;-)

Serg

The two methods are different ,too, by the way

Fabby

19:28

I'm dumb, but not that dumb! ;-)

(There is more then one way to kill a cat)

@RPiAwesomeness: Don't you have a cat? ;-)

Serg

@Fabby You're anything but dumb, my friend; I wish I worked on so many systems like you

Soooo, suggestions - how should I edit my answer ?

Fabby

Went for a smoke...

Lemme have a look...

Look what happened! I just had a look! ;-)

They're both good... Make it two answers!

Serg

Thanks @Fabby ^_o . Wait. Two answers ?you mean to separate them in two separate posts ?

Fabby

(You can do that... Look here )

Yippie! Another gold badge!! (Why am I so happy about a stupid virtual badge???)

Serg

and I though that was frowned upon as polluting the answer section area

Fabby

19:44

:D Hey, I'm not a mod, but both answers are actually good...

(and one is completely automated)

Serg

Edited the answer to separate into two methods

@Fabby wow, that was cool ! Helps the users

Fabby

@Serg What? I was posting to the wrong chat room

Serg

@Fabby no problem, but still handy ^_0

Fabby

You didn't know about LMGTFY?

Serg

nope

I learn something new everyday

Fabby

19:55

I use it all the time with @ParanoidPanda

RTFM, LMGTFY, ...
