@near ivy yes it is

When I'm running my server

#

I'm trying to send an image through a socket, and this is through my images server. However, I'm not sure if the image has to be in the same directory as my file is saved in.

#

Does anyone know if I need an actual png image or???

storm saffron
#

what

#

wait what

#

the path has to be a file path

#

not an HTTP url

iron hatch
#

@storm saffron What do you mean?

#

I don't understand.

storm saffron
#

you're doing open() on a url

#

which doesn't make any sense

#

oh

If you want to retrieve an image from a url you are going to have to use the requests library

hey folks, any websockets users in here? I'm running a dummy client against my websockets server with a bit of slow message handling on the server side and my server just crashes under load... it seems to be a crash within websockets:

  File "/usr/lib/python3.7/site-packages/websockets/protocol.py", line 838, in transfer_data
    await asyncio.shield(self._put_message_waiter)

Hello #networks new to this flavor of python. Attempting my first 'monitoring' script where I check to see if google is up and running. When testing, I simply unplug my ethernet cable...trying to sort out my error handling.

gaierror is just for DNS related errors unless I'm mistaken.

You probably want to catch ConnectionError too

@ember ledge thanks for the response <3. I'll look into adding ConnectionError.

Hi, I’m usually lurking in #web-development but I have a really odd network issue. I need some advice if anyone has any. Recently deployed a django app on windows with Apache/MySQL. Works fine for most, but we’re seeing an issue with random users that are unable to reach the site. The server receives the SYN. Server just doesn’t respond to the traffic at all. Client can’t even ping the server—no response. If we ping that client IP from the server, suddenly the two hosts can communicate. This is even happening with hosts in the same network. I can’t imagine that has anything specifically to do with django or Apache as ping is also affected. Have any of you experienced an issue like this or have any suggestions?

storm saffron
#

Where's it hosted

#

The Django app

#

And the gateway I guess

honest silo
#

It is hosted internally, gateway correctly set to the upstream firewall/router

#

It’s a windows 2019 VM on ESXi

any way you could establish and AP and STA at the same time with one wifi chip? the idea would be to have two separate wireless interfaces perhaps?

hey, what can i do to receive multiple client responses at the same time?

        print(addr[0] +" joined.")
        clients.append(conn)

        if not clients:
            while True:
                if clients:
                    break
        
        else:
            clientresponses = s.recv(1024).decode()

You have a few options. Spawn a thread for each connection, use the select/selectors module to wait on several connections at the same time or even use asyncio instead.

When I have an rest api and it gives you a json with 60 items back is there somehow a general way to say the api I just want 10 items ?

I'm trying to build a structure for tcp connection to transmit data, I do not understand what value to put as a checksum or the point of it. And after getting a syn ack how do I continue to transmit data? Can I put data in the first syn request to a server? Please help

#

what are the rules for the checksum?

#

is it suppose to be the entire header and segment?

ember ledge
#

I have no clue, I'm aware it's to make sure the data is given to the right host

#

A checksum is a pseudo header

And it's a segment

@prisma cobalt you could have a running process in a machine inside your home network, curling ifconfig.me parse out the ip and auto push it to your github repo.

hey guys im trying to coummicate with asp.net code and python code in same server or computer how can i do that most effectively?

#

asp will receive the request and forward it to python and vice versa

summer wren
#

@prisma cobalt You could just send an email, or discord message with the ip though.

prisma cobalt
summer wren
#

The computer runs your program, checking its external ip every t (second, minute or hour) if it has changed since last sendt message it will send a new message.

#

Very easy to write such a script or program.

#

@prisma cobalt Use cronjob or task scheduler to execute it cause its safer then a long running loop.

prisma cobalt
#

@summer wren out of interest, if I had a static ip server in between, sure both devices could connect to it but how does the server keep track of the home router to send messages?

How does an app like Instagram send notification to my phone on my network

  1. I have a dynamic ip
  2. unless there’s a socket open at all times how does Instagram know which port to send data to
  3. how does it work really?
storm saffron
#

Your phone polls Instagram's servers constantly to check for any new messages @prisma cobalt

#

There are also methods like websockets or ways to keep the session alive that prevent needing to issue loads of http requests

I'd like to receive an audio stream over UDP and some data telling the application where to send that audio stream to in byte form. How would I go about this? Should I try tagging the routing instructions at the start of the audio frame and then split them back out afterwards or send and receive the instructions via a different protocol and socket entirely?

Hey, I know that's it's bad practice to treat sockets as message-based, but is this appropriate for a UDP socket?

def recvall(sock):
    data = b''
    part, addr = sock.recvfrom(4096)
    data += part
    while not (len(part) < 4096):
        part, new_addr = sock.recvfrom(4096)
        if new_addr != addr:
            raise Exception('Address change from ' + render_hardware_address(addr) + ' to ' + render_hardware_address(new_addr) + ' during recvall()')
        data += part
    return data, addr```
`render_hardware_address` simply takes `(host, port)` and turns it into `'host:port'`

Just look at the response header @torn imp

HTTP location

The HTTP Location header field is returned in responses from an HTTP server under two circumstances:

To ask a web browser to load a different web page (URL redirection). In this circumstance, the Location header should be sent with an HTTP status code of 3xx. It is passed as part of the response by a web server when the requested URI has:

#

but it just wont work

and idk why

clear bobcat

clear bobcat
#

Probably?

sterile igloo
#

definetly

#

wifi's the one

clear bobcat
#

Can you see connected devices using router software?

#

Like enter 192.168.0.1 or something similar site

sterile igloo
#

u mean the ip of my device?

#

e.g. https://MYIP

clear bobcat
#

Okay, first of all - both of your devices are in same network?

sterile igloo
#

yup

clear bobcat
#

Then open browser and navigate to your router management site - for me it's 192.168.0.1

sterile igloo
#

am i supposed to have one?

clear bobcat
#

You should be able to check all connected devices to your WiFi network

sterile igloo
#

i'm not the one who owns the wifi or anything

clear bobcat
#

Which OS do you have on both devices?

sterile igloo
#

ChromeOS (linux) and android

#

i got a linux thing running on android tho

clear bobcat
#

Android should show you local IP address in settings

sterile igloo
#

got it

clear bobcat
#

Use iftables or something similar to get local IP address of ChromeOS device

sterile igloo
#

got that as well

#

i think

#

i got two adresses lmao

clear bobcat
#

So you can use local IP addresses to communicate both devices

sterile igloo
#

of which device?

clear bobcat
#

What?

dreamy patio
#

Open a command line and try to ping from 1 device to another

sterile igloo
#

hmm

#

with what command?

dreamy patio

Ping 192.168.1.2 for example

sterile igloo
#

i know the ping command but i've never pinged another device

#

ooh

#

k

#

lemme try

dreamy patio
#

Whatever the ip address is on the other device u are trying to reach

sterile igloo
#

it's working

dreamy patio
#

OK great so you know the other device is reachable

sterile igloo
#

yup

dreamy patio
#

How are you trying to communicate between the two devices in your code? TCP port?

sterile igloo
#

i think so

#

i'm using socket

#

just the normal bind((addr, port)) thing

dreamy patio
#

OK is there a firewall on the destination device perhaps that is dropping the packets to the port?

sterile igloo
#

not now pls

sterile igloo
meager wadi
#

hi, can I run a function from another device using a server?

sterile igloo
#

probably

#

u can prob just do smth like ```py
when receive:
os.system(receivedmessage)

dreamy patio
#

Normally I would use something like tcpdump to see if the outbound packet is reaching the destination address or is dropped earlier

iron fjord
#

im sure this is a basic question but how could i check how many messages im receiving from the server

Hello everyone!
Are there any (py)zmq specialists around here?

Nevermind. Found the solution.
For anyone interested: If you want to discard old messages,

then each recv is correlated to each send

how can one test ping with sockets?

clear bobcat
dreamy patio
clear panther
#

since RTT is made up of time for client request to reach server + time for server response to reach client, I'm wondering if there's a way to measure both separarely

#

but I guess I can just take 1/2 of the average ping for a rough estimate

dreamy patio
#

Perhaps but what would be the reference point to measure against? The clocks would need perfect synchronisation to calculate the one way trip time on the reciever

#

Network elements would probably prevent this being accurate as the sender and receiver clocks would never be perfectly in sync

#

I suppose ita feasible in some kind of ideal environment but if you had that then you would have synchronous trip times anyhow

clear panther
#

it's ok I just needed to know whether the ping result is RTT or not that's all. taking 1/2 of that as an estimate should be good enough for me, I don't need it to be so precise

Does anyone have any idea why post is equal to [] but when I check the posts stream through redis-cli it has items in it? When I append a new item the post is still equal to []

async def post_event_generator(request: Request, userID, redis: aioredis.Redis, latest_post_id: str = None):
    delay = 3
    while True:
        if await request.is_disconnected():
            break
        post = await redis.xread(["posts"], timeout=15)
        yield {
            "event": "OK",
            "data": {"test": True}
        }
        await asyncio.sleep(delay)

Hey guys so for the past weeks I was trying to make 2 sockets communicate with each other, it worked and everything was fine until I gave my friend the client file and he wasn't able to connect. I googled the problem, and it turns out I should port forward I did that but it didn't work so someone recommended ngrok for me but I had a very long discussion with a dude about how I can make it work and my friend was not able to connect can someone honestly help me?

@earnest storm are you sure the port forwarding worked? It's easy to check

Guys I would like to send an email with Python, I found online that I have to connect to an SMTP Server like smtp.gmail.com but I don't know if the people that will use the program use gmail (and it doesn't work with 2FA I think).
Is it possible/reasonable to create a temporary SMTP server on localhost and send the email with the local host? So that I don't need a password and I don't need an account on any other platform

clear bobcat
#

Despite of this, when you are connecting to Gmail's SMTP server you are using your own account, not anyone else so you should know password and other factors to successfully authenticate

kind bridge
clear bobcat
#

I don't get it

#

If you want to send emails to users you can connect your Gmail account to your application and you can send emails to whoever you want

#

You don't need any details about receiver's account

#

Except email address ofc

kind bridge
#

Yes okay but I cannot store my gmail password in the code

Hi

#

I need a resource or anything that can help me in building an ICMP scanner, basically I want to build the equivalent of ping but something shorter just to see if an IP address is live or not, any ideas where I can begin?

#

If you want to do it yourself you need raw sockets for icmp and build the packets etc..

prisma cobalt
#

a pure python ping implementation 😂 the real question is why

ember ledge
#

Why not, its not like you will send 1 million icmp packets per second

prisma cobalt
#

Fair enough, and for the learning experience

#

But if you were checking if an ip was open surely you would just use a try except block to simply connect a socket

ember ledge
#

Ah yes good point i was assuming OP had a specific reason to want ICMP

#

@ember ledge thanks

#

@prisma cobalt I didn't know any other way but now that you said something about a socket, I am wondering if that's simpler and can you give an example?

#

initially I thought a TCP handler would do the job but from my networking experience icmp works all the time no matter what type of firewall is installed

dreamy patio
#

Ping responses aren't usually blocked whereas a tcp or udp socket could be so ping serves a lot of use

#

Ping is a great way to test basic reachability

prisma cobalt
ember ledge
prisma cobalt
ember ledge
#

I don't think so, I have to go back to my notes

#

checking...

#

@prisma cobalt ICMP doesn't use any port

prisma cobalt
#

Port 7 my bad

lunar veldt
#

no.. its port 7

prisma cobalt
#

Oh my bad again

#

Wait...

lunar veldt
#

it's called echo port

prisma cobalt
#

Ok try opening a socket on port 7, I think your gonna have to portward tho

#

Does the router intercept traffic on port 7 then to reply to then? I don’t understand

#

A computer shouldn’t need to be on in the network to check if the ip is active

lunar veldt
#

you can't open a socket on port 7

#

ports lower than 1024 are reserved to the system

prisma cobalt
#

Unless python blocks it you can still open a socket to those system ports

#

Just don’t be surprised if it doesn’t work

lunar veldt
#

it won't

prisma cobalt
#

If you ping an ip (which defaults to port 7) is it the router that responds ? Since you don’t need a computer to be on for the ip to be open

lunar veldt
#

Yes, you can still ping it if the router is open

prisma cobalt
#

So the router intercepts and responds to all requests on port 7?

lunar veldt
#

yes

prisma cobalt
#

Any other ports the router automatically intercepts and blocks?

ember ledge
#

I think you need root/sudo for raw sockets. Else i havent used scapy in a while so I dont remember the specifics

#

Also icmp doesnt have ports in the udp/tcp sense but packet types. And you can definitely block ping too with e.g. iptables

#

The OS answers to ping, if it is allowed, so you dont need a process to bind the port (there is no port)

prisma cobalt
ember ledge
#

Huh there is indeed this on port 7 https://en.m.wikipedia.org/wiki/Echo_Protocol

But its not what people generally mean with ping

Echo Protocol

The Echo Protocol is a service in the Internet Protocol Suite defined in RFC 862. It was originally proposed for testing and measurement of round-trip times in IP networks.
A host may connect to a server that supports the Echo Protocol using the Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP) on the well-known port number...

#

"On various routers, this TCP or UDP port 7 for the Echo Protocol for relaying ICMP datagrams"

#

I doubt this is avaible by default on many hosts these days

ember ledge
ember ledge
#

would i look for help in or somewhere else

dreamy patio
prisma cobalt
#

ah yep, someone on a defference server said. A packet is sent to the router with the ICMP protocal in the protocol section of the packet header right?

#

no port needed

#

then the router responds

#

is that right?

dreamy patio
#

ICMP operates at network layer its not port bound

prisma cobalt
#

yeah so is the process i said above correct?

dreamy patio
#

The router will respond if that's the IP address you're pinging otherwise it will just forward it

#

If the router is 192.168.1.1 and you ping that address then the router will respond yes

prisma cobalt
#

but the thing about the ICMP thing in the header?

#

thats how the packets work?

dreamy patio
#

Yes it's protocol 1

#

In the header

#

RFC792 for ipv4

prisma cobalt
#

So it arrives at the router which decodes the header and sends back that it’s online and healthy

dreamy patio
#

Exactly

prisma cobalt
#

Hmm surely that could be used as a dos vulnerability since decoding the header might not be strenuous but it isn’t free

dreamy patio
#

Echo request from source and echo response from destination

prisma cobalt
#

What?

dreamy patio
#

That's a ping essentially it's an ICMP echo request/response

prisma cobalt
#

But if it takes a tiny bit of computing power to decode the header then, with enough requests it could shut down the router no?

#

Aka a dos attack

dreamy patio
#

But not most effective form of ddos

prisma cobalt
#

Hang on, if I’m not mistaken it doesn’t matter if it’s ICMP cause any packet sent will have to be decoded right?

dreamy patio
#

Yeh but icmp is lower layer so not much overhead there

ember ledge
#

For whatever reason I couldn't get scapy to work however I found another tool and made something out of it that works:

import pingscan, sys

def ip_scan(ip):
    if len(pingscan.scan(ip)) <= 0:
        status = False
    else:
        status = True 
    return status 

print(ip_scan(sys.argv[1]))
ember ledge

iron fjord
#

is there a way to get a bool value on weather the client is connected to a server?

Hi again

#

How does one recognize an IP address that's behind a CDN like cloudflare?

#

I just think that I need to get rid of any IP that's behind cloudflare because I cannot do a reverse IP lookup on them, any ideas how to get rid of them?

clear bobcat
ember ledge
#

I don't want to bypass cloudflare protection, I am asking how do I know if x.x.x.x is behind cloudflare

clear bobcat
#

Oh, my mistake

ember ledge
#

@ember ledge I need something to implement in my own project, I found this site which shows the IP's ISP as Cloudflare which is good enough:
https://whatismyipaddress.com/ip/104.21.12.42
however I don't know how to do that on python, I can of course use this website and then scrape results but I don't want to scan all IPs using this website, it's gonna cause a DoS attack

#

that doesn't give me what I want

#

I don't know how to do that on python
Send a GET or POST request

it's gonna cause a DoS attack
It's not, don't worry about it

#

Any modern web servers on any serious server can handle millions of simultaneous requests

#

No, from where I see it, it's gonna be an overload on that service, how can I implement something on my own?

#

ah right, because I was about to do 4 billions 😛

#

You only want to verify IPs that connects to you, right?

#

If not just throw in a second sleep timer after a few hundred thousand requests

#

but what if I wanted to do implement something like that purely in python?

prisma cobalt

Try a form of compression to speed it up

quasi juniper
#

anyone knows the difference between

`header = {'Authentication' : 'Bearer' + token}

header = {'Authorization' : 'Bearer' + token}`?

I know AAA, i know basic / bearer, but some examples from another API environment seem to use authentication vs authorization randomly, and i cant see a pattern?

clear bobcat
quasi juniper
#

in the specific context of HTTP headers, yes - or rather if Authentication in the header is even a thing, because i cant find anything on it

teal roost
#

isnt it just what authentication and authorization literally means ?? 🧐

#

normally to authenticate , u usually send authorization in the header which contains your credential (based on that ur gonna get authenticated) ----> for basic authentication

ember ledge
teal roost
#

and other interpretation for authorization can be if that token holder are able to request for performing certain task (like if they are admin , or just normal stuffs ) and authentication can be just authenticating the user credentials to sign in ---> for oauth

quasi juniper
#

you usually just send authorization + bearer/basic with a token. the question is if the header is still valid if you write Authentication instead of authorization, or if that is not a thing in HTTP headers

#

when i replace Autho with Authen 1:1 i get a 401 error, so im assuming it dont work like that

teal roost
#

Hmm iirc it sud work thinkmon

#

If the authentication worked

Ur doing it in the same session y3?

"sup" represents a sequence of unicode codepoints, but networking operates on sequences of bytes. In order to get a sequence of bytes, you can do b'sup'

or "sup".encode(some_encoding)

shy island

@shy pebble but there's a problem

thats why i was not using b prefix

it prints b itself

shy pebble

print once again takes a string. So you need to decode the bytes into a string

which you do with some_bytes.decode(encoding)

What do you think? I don't want to spam, I'm only asking for code review and things like that (it's only 100 lines of code)

I've set up a socket server and clients for my game, but I might did some oppsies and it's not working as I thought. I was thinking of two different computers can see their opponent's score in sync.

#

I am using selenium to do web scraping and using some proxies with auth and there is no way with chrome to set up a proxy with auth using the headless mode, therefore I am looking into setting up a local proxy with no auth which will then forward the request through one of the proxies with auth that I have

#

Anyone have any libraries or examples to get that going quickly?

solar oyster
#

Are all the internet methodologies used 30, 20 years ago still in use today?

Anyone have any experience using mitmproxy to forward requests through another authenticated proxy `?

hey

rose patrol
#

i can't get the ip

#

like i have it working on their localhost but idk the ip so idk how to connect

#

:c

boreal crane
#

hmmmm

#

is there any chance you could use an http server instead?

#

they're easier to work with on repl.it

#

if not, still set up a simple flask webserver, then you can get the URL for your webapp

#

use an ip lookup tool to get the ip from the URL

rose patrol
#

can you help me convert my app to that @boreal crane cause im confused

#

lol

boreal crane
#

well, what are you using the socket server for

rose patrol
#

chat app

#

gonna send you the link in dm

#

@boreal crane accept fr

#

you there?

boreal crane
#

yes

#

dms are closed

rose patrol
#

i see

#

cool

#

just open the link then ill delete it k?

boreal crane
#

so, you could make the socket server an http server instead, that has more benefits anyway

#

is your chat app 1 on 1 or group?

rose patrol
#

group as many people can join

#

as they want :c

#

what is your repl username

#

:c

boreal crane
#

not necessary cuz here's what you're going to do

rose patrol
#

cool

boreal crane
#

your server.py will have a simple Flask server to handle incoming REST requests

#

google these terms to learn more

rose patrol
boreal crane
#

it's the same logic as your socket chat

rose patrol
#

i didn't make it :c i followed a tutorial :c

boreal crane
#

just use a flask server instead

#

oh

#

then you can either change it to use an http server or you can host it on something other than repl it

#

but no one really uses raw sockets

rose patrol
#

how

Hi. i have a tiny noob question:
I'm messing around with python socket and i came a cross a problem....
Computers outside my network cannot connect because my router blocks them. Right? anyway, i looked it up all day and the only thing i found about it is that i need "port forwarding". I also saw something called "UPnP". The only thing i know about it is that: it can forward ports.... Again, i'm a total noob at networking..... Anyway, is there a way i can maybe use UPnP in python (if it has anything to do with my prob) or there's other stuff i can do about it?

clear bobcat
prisma cobalt
#

Look up the steps of port forwarding for your router

velvet lichen
#

but UPnP has anything to do with port forwarding? just wondering.

prisma cobalt
#

You only need to portforward lol

#

I’m not familiar with UPnP but I myself have portforwarded several ports to alllow connections

velvet lichen
#

ok. btw, should i be worried about security while port forwarding?

Where can I learn the inner mechanism of a VPS hosting service?
I mean the protocol, VPS management, VPS management automation, user dashboard, VPS building automation after purchase or after order, IP management, backup management, user admin services etc.....
I mean the whole system if I want to start my own VPS hosting business, not the reselling one.
Can anyone please tell me if you know anything?

gloomy root
#

That is a incredibly big task for a single person todo

#

you need to buy the servers, the internet, the ip blocks, the panels, build a dashboard, setup micro k8s, setup licenses, repos, virtual routers etc....

#

handling billing

#

handle load balancing

#

handling data protection

#

handling security

#

the list goes on

sterile loom
#

No, I am not doing it alone. I also have my friends on it. Is there any source where I can learn the building process of this system? If you know please kindly tell me. @gloomy root

gloomy root
#

i mean its not something you just follow an article on

#

its hundreds of tools and software

#

and btw, if you're under 18 then you legally shouldnt be trying to make a hosting company

#

if you're over 18 i still recommend you consider the legal implications before doing anything

#

and then you're gonna need to get really good at dev ops tools like K8s, look into spend a few thousand on Ips and servers etc... atleast

outer mirage
#

yep. starting a hosting company is expensive and legally challenging. i urge you to talk with a lawyer about the legal requirements.

sterile loom
#

But why can't I start it if I am under 18?

gloomy root
#

because of the following

#
  1. you're not old enough to sign legally enforceable contracts in most country
  2. you often lack the maturity and skills to provide the services that you offer to a reasonable standard
  3. you lack the funds, hosting company cost tens of thousands for even a small system, even a small hosting company will put hundreds of thousands of dollars into setup and infa
  4. you're not old enough to sign for commercial contracts with internet providers
  5. You're not old enough to understand how much liability you put yourself under with GDPR
#

If i am a customer of your company

#

and you have a security leak and my data gets leaked as part of that

#

i can guarantee that im going to be coming after you with a lawsuit miss-handling my personal data

#

And im sure your parents arent going to be happy if you have to turn up to court and pay and incredibly large amount of fines just from one person let alone if others took action

sterile loom
#

I see....

gloomy root
#

and then we get onto the other point

#

you got a data center laying around? if not, get ready to buy commercial spaces

Hi!
I want to communicate between two devices on the same network.
The communication doesn't need to be bidirectional, but I need it to be as quick as possible.

gloomy root
#

for what purpose?

hardy hatch
#

I need to send GPS coordinates between devices.

#

I am thinking between using sockets and Mqtt.

gloomy root
#

well for the fastest method would be UDP sockets

#

however

#

they're un-reliable transport

hardy hatch
#

Mqtt is sweet since it is easy to use and it should be quite performant.

gloomy root
#

easiest is probably Websockets offer good latency while being relatively simple and easy to use

#

but anything like http request or that are gonna be about the same time in reailty

#

only a couple ms betwen the two but you're looking at probably at most 5ms around a local network providing you're not on some 50kbps local network or smth

hardy hatch
#

You think that websockets are better than plain mqtt?

gloomy root
#

shrug depends on what you want todo and their implementations

#

typically with MQTT implementations have a decent amount of extra processing but ig try it and see

hardy hatch
#

okay

#

another quick question

#

do you have any tips for me how to handle latency and dropped packages?

#

where should I get more info? what to look for?

gloomy root
#

well for dropped packages you generally shouldnt worry if its via tcp because it's reliable

#

if you're talking about say multiple workers and if a worker goes down the task isnt lost then RabbitMQ is good

#

but equally that increases latency

I understood why I should learn DevOps but I can't understand why should I learn k8s regarding yesterday's topic. (My knowledge is very low on k8s)

gloomy root
#

Which is exactly my point in why you ahould know it

#

But this goes back to whole: setting up a hosting company is a really bad idea for a group of kids or even a group of adults todo

supple oak
# 
# (TCP)
# CLIENT
with open(src_file, "rb") as f:
    l = "1"
    while l:
        l = f.read(4096)
        sock.sendall(l)
# resp = sock.recv(1024).decode("utf-8")

# SERVER
with open(dest_file, 'wb') as f:
    l = "1"
    while l:
        l = clt.recv(4096)
        f.write(l)
# clt.send("0".encode("utf-8"))

so if i execute this code alone the program(s) run correctly. but if i do the same with the post-file-sending part uncommented, it just halts. why?

prisma cobalt
#

Change l = “1” to l = True

supple oak
#

hows that gonna change anything, the file does pass over through the socket in both cases

prisma cobalt
#

Is there an error?

supple oak
#

so the program does enter the while loop

#

no

#

it just halts, stays completely still

prisma cobalt
#

Hmm

#

are you sure it’s relieving data?

#

Cause the .recv is a blocking method

supple oak
#

yeah

#

like i can literally open the file once its done sending the data, even though it halted right at the end

#

hmm

prisma cobalt
#

You know every time you run the server script the file wipes itself before writing data

#

Just checking

#

I can’t see an issue from that tho

supple oak
#

can i alternatively just close the socket and then reopen it?

Hello if i will send via sockest smth like that send(f"some text & {pickle}") how i can depickle pickled object in reciver site?

shy pebble
#

you will need to send the size of the pickle or some other way to determine where the pickle ends

clear bobcat
ember ledge
#

sending works fine, but there is string insted of pickle, i was trying to msg.split('&') but there will be still lists of strings

#

and i can't unpickle it

shy pebble
#

keep in mind that single a send could be multiple receives

#

and a pickle can contain any bytes, including &

ember ledge
#

Hmm, can you help me if i write you code? Im new in sockets

shy pebble
#

you do need a size, so that you know how many bytes to receive in order to get the complete pickle

ember ledge
#

yeah i got size as well

#

while connected:
msg_length = conn.recv(HEADER).decode(FORMAT)
if msg_length:
msg_length = int(msg_length)
msg = conn.recv(msg_length).decode(FORMAT)

#

is from server loop

#

def send(msg):
message = msg.encode(FORMAT)
msg_length = len(message)
send_length = str(msg_length).encode(FORMAT)
send_length += b' ' * (HEADER - len(send_length))
client.send(send_length)
client.send(message)

#

if from client site

#

send(f"smth &{player_class_dictionary_global_ready_to_send}") this is the send commend i try to use

shy pebble
#

try smth, ampersand, pickle = msg.partition(b'&')

#

also don't decode the received bytes if they contain a pickle

#

since well, a pickle isn't text

ember ledge
#

okey so there will be smth like that msg_pickle = conn.recv(msg_length)

#

smth, ampersand, pickle = msg.partition(b'&') where i have to try it?

ember ledge

If you @shy pebble or someone else will be kind to show me how to loads pickle in that loop, i will be more than greatfull
