Go down, theres a security section :)

Remote keyless system

A smart entry system is an electronic lock that controls access to a building or vehicle without using a traditional mechanical key. The term keyless entry system originally meant a lock controlled by a keypad located at or near the driver's door, which required entering a predetermined (or self-programmed) numeric code. Such systems now have a...

Hello! I'm making a server with the socket library, but don't know what localhost port to use. Maybe the port I choose is used by some other application. How do I decide a port for my server?

ember ledge
#

just a heads up, it wont be secure if u do that

#

there WILL be cracks

#

use an open source ready made server

#

unless u want to learn how to make one, go ahead @digital ether

ember ledge
#

im not sure but im just giving a heads up if u want to use it for something formal

#

using a ready made and well known DB server is better

prisma cobalt
#

the system used is the same as how would open a garadge door i believe, the key and car have a chip that changes the value of each request based on an algorithm with a seed only the car and key know, so if i were to record the open request from you key and try to open your car with that data the next day lets say, it wouldnt work because when you unlocked the car, the key and car both did a +1 in their programming and the unlock request data is different now

#

the reason this gets bypassed is this:

  1. if i block your first request to unlock and record the data of the request
  2. you press the key again, assuming your too far away or you didnt click it hard enough
  3. i record the second request and then play the first recorded data back to the car which unlocks it
  4. i now have the data on the next request from the algorithm meaning i could unlock and potentially steal your car anytime
#

that make sense?

#

also i think there more going on behind the scenes so make sure you check it out properly

Sorry, I didn't understand this

So once you have a radio receiver device

#

you'll need a device driver and a python interface to that driver

#

Even at this point it's not clear what data you are expecting, and I haven't worked with radio waves before, but i don't assume you're trying to tune in to FM 106.5 and play the station

Hey there everyone! 👋 Hope y'all are doing great 🤗

I just wanted to ask a question,
I have a socket chat application, but Instead of threading and making it complicated, I would rather stick to asyncio. Is there anyway to have a clean Asyncio Approach to making such huge chat applications?

Please guide me 🙏 and Do link to anything external if possible, Appreciate your help a lot! hehe

tough dagger
#

I have no idea how the mentioned library work, but yes if you have plain pocket data you may get plain text from it. Just that it will require to handle extra stuff to glue the message / probably just data. Bytes to string is quite simple, but content may use different encoding than ANSI-US / 7-bit, and it means that anything past CR LF CR LF needs to be decoded based of what's in header. Also header itself might require URL decoding. That's just very simplified case there's more like sessions over same connection. HTTP under SSL/TLS, requests muxing, multi-part, .... Let's say it's not that simple and takes some time to implement properly and if you do want it it's more like exercise.

Hey everyone!
I'm trying to program a simple server which constantly receives files from a client across separate computers. I was wondering if the following code could work on separate computers:

Server (file receiver):

import socket

while True:
    try:
        s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
        s.connect(HostnameOfTheClientComputerGoesHere, 8080))
        receiving_file = open(FilePathForTheIncomingFileGoesHere, 'wb')
        filedata = s.recv(1024)
        receiving_file.write(filedata)
    except:
        pass

Client (file sender):

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((socket.gethostname(), 8080))
s.listen(1)
while True:
    conn, addr = s.accept()
    break
epicmoners = open(FileToBeSent, 'rb')
monersread = epicmoners.read(1024)
conn.send(monersread)

Sorry for the weird variable names

fierce pivot
# thick pivot Hey everyone! I'm trying to program a simple server which constantly receives fi...

Well, maybe u should modify some things :

Foa, u should make that SERVER will bind, and client will connect. It's good to do that because server ça be online and client not.
But it should work, if u change, on the actual client py s.bind((socket.gethostbyname(), 8080)) by py s.bind(("0.0.0.0", 8080)). It work better because it is bind on every network that is aviable, such as ure lan and/or internet.

After, i wrote the entire code. If u dont want to see it, just dont look ;)

||Client

from socket import socket, AF_INET, SOCK_STREAM
PathToFile = input("Please enter file path : ")
with open(PathToFile, "rb") as r:
    data = r.read()
s = socket(AF_INET, SOCK_STREAM)
try:
    s.connect((ServerIPAddress, 8080))
except:
    print("Could not connect to server !!!")
s.send(data)
s.close()
print("Done !")```

Server
```py
from socket import socket, AF_INET, SOCK_STREAM

s = socket(AF_INET, SOCK_STREAM)
s.bind(("0.0.0.0", 8080))
s.listen(5)
while True:
    conn, (ip, port) = s.accept()
    print(ip, "connect !")
    data = conn.recv(4096)
    pathToFile = input("Please enter place to save file : ")
    with open(pathToFile, "wb+") as r:
        r.write(data)
    conn.close()
s.close()```||

for one in your client, if it cant connect to the server then it still trys to send data lol, resulting in an error

also this makes the assumption that the file is under 4 kilobytes, it wont work if its more (which is very likely)

Is there an easy way to convert chars to ints that both python and c++ support? I know that python has ord(), but I am not able to find a similar solution at the c++ side. Thanks in advance

ord() just converts the UTF-8 character to it's UTF-8 integer representation

Y’all I’m having trouble understanding how my Western Digital My Cloud EX2 Ultra private cloud works. I’m using the WD My Cloud OS 5 which allows users to create an account to access the folders they have permissions to. Are my files uploaded to WD cloud servers or is this all happening through my NAS?

Forgive my naive question, I know very little about networking, NAS, private clouds, file servers, etc.

Hi

#

I need to connect to a layer 2 cisco switch

#

I'm thinking of using SSH, with paramiko or netmiko

#

I wanted to ask, I can set any IP address (for example on vlan1) and use it for SSH?

#

or do I need to like get permissions/ buy an IP address

keen horizon
#

I'm a little confused about what you mean.

You're inside your own network?

Keep in mind Layer 2 switches deal with switching based on MAC addresses not IP addresses. But I don't know what you all have set up.

radiant vortex
#

nothing so far

#

It's for a uni project

keen horizon
#

kk

radiant vortex
#

so what I want to do

#

is configure a switch using python

keen horizon
#

k

radiant vortex
#

so can I assign an Ip address to Vlan 1, then SSH to it

keen horizon
#

so the layer 2 switch itself has an address and ssh port you can connect to?

radiant vortex
#

that's what i'd set up

keen horizon
#

how would you connect to it to do so?

#

you have console access to it?

radiant vortex
#

i'd use console port

keen horizon
#

gotchja

radiant vortex
#

so I'm buying a new switch for the project

keen horizon
#

ah!

#

I was thinking some remote switch you had no access to so this was confusing

#

and this is all self-contained -- you hook this all up and you're not putting it "on" the internet right?

#

there are non-routable addresses available to you for private use

radiant vortex
#

could I still SSH to it if it isn't connected to a router?

keen horizon
#

if you put the switch and the machine running the python code on the same ip range yes

radiant vortex
#

ok

#

ty

keen horizon
#

yeah so looking around Layer 2 switches can be managed and provide a port and address. Likely unless you run DHCP you'll have to assign it an address like 10.0.0.1 on that vlan port when you're in console. And then your python machine can be 10.0.0.2 and you can then talk to it.

If there is DHCP on this network, your machine and the switch will likely pick up an address automatically. So have fun figuring that out.

But if this is all self-contained (your machine + switch only) for demo purposes, you have full control over using any of the RFC1918 non-routable addresses (you've seen and used them probably .. 10.0.0.0/8 or 192.168.0.0/16 for instance). I think there's one other but those are the ones I use most often.

#

good luck with your project

radiant vortex

Tried using ctypes and time modules.. but the code crashes sometimes

To raise an exception if the thread is alive after the specified time

Consider a client-router-server network. Clients request for information from the server via the router. Every server has a backup in case it fails. How will you ensure data consistency after using the backup server when the main server fails?

my answer is that by repeatedly updating the backup server like updating every 5 min for instance so the data consistency will be there , am i right or do you guys have some other answer or way to maintain consistency ?

What libraries do you believe that requests uses?

thats why i said usually people just use http requests instead of interacting on a raw socket basis

You’d save tons of time just using a library for such. All the way down to a low level, each request is made using a socket. The kid has the right idea, but the wrong way of carrying out such.

ember ledge
#

why are you trying to do this exactly

teal elm
#

He's trying to grab the csrf that is set by the post requests probably because he needs for a header

#

@flat rain go to main page load it look into the html search csrf should be in there then it's probably a header that's added to the post request

#

Use fiddler or something to see the requests or even debug menu in chrome

#

@flat rain feel free to dm me for more help

Is there a way to do something like this?

Consider me a complete noob because I totally don't how to do what I am about to say or even if I'm in the right place for it, can we upload images to some sort of a temporary server or website atleast 1 image per second with enough speed that discord can render it like a really low fps game in an embed ||yes this is a discord bot project idea||

steady horizon
stray jungle
#

Well we could change the source and leave the end link the same 🙃

steady horizon
#

That... idk... honestly

stray jungle
#

Is there a database of sorts that can handle images really well?

steady horizon
#

You will probably need to refresh the channel or click the image again or something though idk

steady horizon
#

and it's not the right channel to ask that question in

stray jungle
#

🙁

#

I've had this idea for multiple months now and my knowledge of python is very low and am just being desperate at this point

#

Because if this is possible it'll be a brand new way in chat games

steady horizon
stray jungle
#

I might have been talking bs, cuz I clearly have no clue what I'm talking about

steady horizon
#

@stray jungle user-experience-wise, I think it's a horrible idea, as I don't think snake on Discord like that would be fun to people who can't type fast for responses, and buttons aren't fully out on discord.py

stray jungle
#

The closest solution I found was to use imgur, but I can't even figure out how to upload an image

Thanks for ur time tho

Just if you see a chat game blowing up some day just remember where u heard it first || jk I'm just fantasizing at this point 😂 ||

stray jungle
steady horizon
#

good luck bro honestly

stray jungle
#

I have almost 50% of the plot for the game planned out

#

If this doesn't happen ig I'll just make a boring old text chat game, like all others

steady horizon
#

Or, you can make a game with PyGame or something, and publish it on Discord's game store.

stray jungle
#

I did think of that actually

#

But I want it to be more like a multiplayer experience

Like it's basically going to be Minecraft X clash of clans but on discord

Any clues, why my Linux server is sending ARP requests for an IP outside of its subnet? Here is routing table and a tcpdump when trying to ping IP from different subnet: https://susepaste.org/view/raw/10043871

proud osprey
#

usually, if you don't do anything on your OS, it will probably rely on what DHCP tells it to do, in your case your router. If you set up something manually then that's what it will use to resolve. You can try dig command to make how names are getting resolved

#

?

Haha, yes, just got the answer from a diff server

proud osprey
#

I thought there was a DNS question here

#

😂

tacit loom
#

Device takes precendence

#

But I have a feeling my hostnames are not getting resolved properly

#

I can't use dig Im runnign android

proud osprey
#

oh you mentioned linux

tacit loom
#

I can test it on Linux, but the issue is on Android

proud osprey
#

though there must be networking tools/apps for Android

tacit loom
#

The issue is Im running any app that caputres packets for each app

#

And sees where they are connecting

#

It becomes ewkfejl2123-fastly.com or some other CDN

#

@proud osprey Any ideas lol?

proud osprey
#

seems like you installed something weird in your phone. I'd reset it to fabric

#

and do not use Google "auto restore" option when setting it up again

#

I'd install all what I need manually and restore/setup each app individually

good luck

hey guys im trying to make a code that tells me when i receive an email i got this online ```import poplib

#Get messages from server:
messages = [pop_conn.retr(i) for i in range(1, len(pop_conn.list()[1]) + 1)]

Concat message pieces:

messages = ["\n".join(mssg[1]) for mssg in messages]
#Parse message intom an email object:
messages = [parser.Parser().parsestr(mssg) for mssg in messages]
for message in messages:
print(message['subject'])
pop_conn.quit()```

#

its not working for some reason

#

obviously i put my email and password in

#

heres my error

I assume issues relating to funky behavior from Requests would go here?

#

I'm working on a Discord bot, and I need to upload a file to temp.sh, and use the response given from temp.sh/upload
Currently, this is what I've got ```Python
import requests as rq

url = "https://temp.sh/"
filename = "test.zip"

with open(filename, 'rb') as file:
res = rq.post(url, data=file)
print(res.text)``` but every single time I print the response, it's just the raw html from the main site rather than the response that should be given after being redirected

static inlet
#

try changing the post to a put

crystal lake
#

put doesn't work with root either

#

but works just fine on /upload

#

My next headache

#

is figuring out the naming

#

because all my uploads are being saved on the server as just upload

#

no extensions, no other filename

#

just upload

#

But that's a headache for the morning

yo, im learning the socket module but i don't really understand something. "A pair (host, port) is used for the AF_INET address family, where host is a string representing either a hostname in Internet domain notation like 'daring.cwi.nl' or an IPv4 address like '100.50.200.5', and port is an integer."(from python doc). but when i use the gethostname method for the host arg it returns my computer name but it doesn't looks like an internet domain notation. So why my computer name works like an internet domain name?

your right in saying it cant be used for external network communication (over the internet)

I think you can iterate over the range of IP addresses and port numbers provided and then see if u can establish a connection. if connected, write the name of service in the file based on the port number or else skip it

This is a port scanner, there are countless examples on google if you need a reference

#

@ember ledge you can send a timed request packets to each port on those ip address, if they are open, you get a response, otherwise they are closed. Then map those open port numbers with the standard services running on those port. hope it helps

Hi. I'm using Flask to create the backend for a non-browser game (with Unity) and have a few questions. Is there a way for the server to push new data to the client without the client needing to query the api at intervals to check if there's new data? I understand there's sockets but how reliable are these? And if flask is not my best option, any recommendations for a non-browser game?

clear bobcat

#

@clear bobcat so basically the option is sockets not the standard way of doing flask apps with routes ?

thanks so much

rose oxide
covert dome
#

@rose oxide any notable advantages/differences between quart and flask?

rose oxide
#

only difference I know of is quart is better as it's async (asgi) and also supports protocols like websockets and http 2

#

@covert dome I'm trying to implement something with websockets too I just got to know about this framework and it works for me. and also you can route the requests as you could using flask.

covert dome
#

sweet... thank you i'll have a look at it. it's my first time using websockets and i jumped right into the deep end with having a network game lol

I want to host a little something I made (aiohttp server) on heroku (which I know is a bad place to use for hosting), but I keep getting 503: Service Unavalivle errors.

I am able to ping from mobile to desktop.. But was not able to the reverse that is i can ping from desktop to mobile

#

Is there any way to do this?

rose oxide
#

5000 will be default port if it doesnt find PORT variable

worldly lotus
#

also

#

what do I set as host?

rose oxide
#

ummm how r u deploying it?

worldly lotus
#

git

#

git add

#

commit

#

push

rose oxide
#

like gunicorn or something?

worldly lotus
#

no

#

python main,py

#

gunicorn is wsgi

#

"asgi"

rose oxide
#

I see

#

I haven't deployed with wsgi

#

I'm lagging wtf

rose oxide
worldly lotus
rose oxide
#

it worked well for me
I used quart framework btw which is similar to flask but asynchronous

rose oxide
#

if I stop lagging ffs

worldly lotus
#

kk ty

worldly lotus
#

There is one thing that is stopping me now

rose oxide
worldly lotus
#

deploying the thing...

#

It runs with uvicorn on my local

#

but when I build it

#

I get no unbinded port error anymore

rose oxide
#

what address do you provide for host?

worldly lotus
#

no wait I use default

#

but I think default is 0.0.0.0

rose oxide
worldly lotus
#

yes

rose oxide
#

I doubt default is 0000

#

try to configure it to 0.0.0.0

worldly lotus
#

127.0.0.1?

rose oxide
#

that's local host most of the times it's the default

#

so better configure it to be 0.0.0.0

worldly lotus
#

k

#

btw

#

but rather

#

web: uvicorn main:app

rose oxide
#

yea it's fine just make sure you bind it properly

worldly lotus
#

will this do?

#

web: uvicorn main:app --port "0.0.0.0"

rose oxide
#

like for me I was not able to connect properly so I ran hypercorn programmatically to get port from os environments and ran that file

rose oxide
#

otherwise u can use hypercorn and make a python file then run it using python

worldly lotus
#

waaiait

#

holy shit

rose oxide

sorry my internet sucks ass today

I think it works

rose oxide

ima test it

first

#

ima finish helping this guy in a help channel

I think its because heroku thinks that a HttpResponse is supposed to be returned

#

but it aint

rose oxide
#

any errors on log?

rose oxide

because of there was no running dyno at all

Hey guys, I need help making a multi-client heartbeat system

#

how would the client know what port to connect to?

rose oxide
rose oxide
worldly lotus

if it's websocket try using ws://

will that work with

python-socketio

#

and FastAPI

#

and asgi servers?

rose oxide
#

it should work

#

but idk about python socketio. you need to implement that asgi callable to run it using asgi server so better use framework

I'm not sure if python socketio is already asgi

it is

I have Spectrum, I have it as a feature technically, but according to the person I spoke with, Spectrum doesn’t like residential port forwarding due to security issues and other reasons. Apparently the newer Spectrum routers don’t have it as a feature at all so I’m “lucky” to have an older router so I have the ability to ~try~ to port forward even though it didn’t seem to work out great for me. Id be able to buy a third party router to do it but I didn’t feel like going through the trouble

I also found a cloud server with the cheapest server option being $0.0075 per hour and considering I just need the server to send small bytes of strings or dictionaries it does the trick just fine

And I got it from Tech with Tim who had a code that gave $100 in credit, since i’m not running the server 24/7, that $100 is gonna stretch far

prisma cobalt
#

Ofc you could have used another site like aws which would allow you to run it 24/7 for a year for free

so im tryna make requests via http,socks4/5 proxy

using socketserver

#

does anyone here know how to do it

ember ledge

Any one knows what to send to a STUN server to get back IP?

#

data

gloomy root
ember ledge

Like this http request how can we request STUN server

import socket

server = socket.socket(socket.AF_INET ,socket.SOCK_STREAM)
ap = socket.gethostbyname("google.com")
print(ap)
server.connect((ap,80))
dat = "GET / HTTP/1.0\r\n"
dat += "\r\n"
server.send(dat.encode())

data = True
while data:
    data = server.recv(1024)
    if(len(data.decode())==0):
        data = False
    else:
        print(data.decode())
        data = True
gloomy root

not sure why you need that in the first place tbh

based on NAT transversal

Also I am trying to counter symmetric NAT

gloomy root
#

then reading is your friend 🙂

ember ledge
#

reading scripts day and night

gloomy root
#

I mean the article i sent does a pretty reasonable job

#

links you to the other set of articles explaining the mesasge structure, sending messages etc...

#

the actual language implementation is up to you

ember ledge
gloomy root
#

its describing the protocol

#

the protocol doesnt change across implementation

ember ledge
#

after all It's just echoing out IP/PORT

gloomy root
#

that would defeat the entire point of a protocol

ember ledge
#

I am just angry why peer to peer doesn't have a uniform implementation over networks

#

p2p decreases every aspect of load to server

gloomy root
#

because p2p is complicated and differs depending on what you're doing with it

#

WebRTC for example has to use several different setups to provide the support across networks e.g. it needs both UDP and TCP fallbacks, TURN servers for when a network blocks Client to client UDP etc...

Hey !
I need some help on a problem (as usual)
I dont realy know if i'me on the great channel.
I want, with a python code (python 3.8) to send a mail.
I searched, i searched, i searched....
I found some difrent things, but lot of them didnt work.
For example, lot of website was talking about smtplib and emails.utils.
Well, that great but... for a gmail account... that didn't work.
After, i found google_api i actualy didn't try, but works only for gmail accounts. That seems great, but i wanted to know if a (great) lib exist, that allow emails from any smtp clients.

Should I use select or threading?

steady horizon
#

Most tutorials on YouTube use a threading mechanism of some sort, but I also discovered that select can be used for asynchronous socket programming.

#

I already know how to use threading for socket programming but I want to know if select has any benefits or if it can help with anything.

lofty bough
#

@steady horizon Instead of using raw select you can use higher-level asynchronous I/O.

#

asyncio has some primitives for working with sockets

steady horizon
#

Hm. Thanks. I will look into asyncio socket programming.

trim moth
# steady horizon Most tutorials on YouTube use a threading mechanism of some sort, but I also dis...

ig select is primarily for knowing about the state of a particular socket (wether is it ready to read, ready to write, or errored) and you can do some decision making based on the state of a socket as explained in https://www.oreilly.com/library/view/python-standard-library/0596000960/ch07s03.html
while threading seems much different tho, since it's like doing multiple different things at the same time, and finally, with async you can use coroutines and set up event loops to create a sort of pseudo-concurrency while a program runs within a single thread

O’Reilly Online Learning
Python Standard Library
gloomy root
#

personally, if im doing any sort of low level socket handling I got with asyncio

#

it makes life considerably easier than worrying about selectors etc...

I am multiple GET requests around 1K using requests library... I guess its a overhead as each request has to setup TCP connection and then make actual request.

Is there any better way to do it ?

fierce pivot
solemn mist
#

@fierce pivot I guess requests lib is using the socket under the hood.

fierce pivot
solemn mist
#

yeah, correct. But my question more towards usage of requests lib 🙂

gloomy root
#

generally, yes establishing connections can be expensive if they're all in a short period of time, but equally not usually enough to be a big issue

#

most of this just comes down to the timeframe of these requests

solemn mist
gloomy root
#

its less the TCP overhead

#

you cant stop the TCP overhead (not that it matters)

#

its the TLS handshakes that tend to take more time, mostly because roundtrips and processing time

#

this is sorta where HTTP/2 comes in

#

basically one connection, many requests

Anyone have a good document describing application headers to use with TCP communication? It is my first time designing an application layer for that.

steady horizon
#

You write your own headers.

#

You are supposed to plan how messages look and build a protocol from that.

past spindle
#

Right, I just would like a look at some common fields before I get a header design down on paper. I am looking at the DNS header right now, and wondering if there are other good examples. I understand that this is a broad question, and specific application headers are designed for specific use cases. I suppose I am just looking for inspiration/guidance.

well, a good starting rule is you don't want to have redundant information in there

you're optimising for size, primarily

Hi, Im trying to make screen sharing program. Im using
PIL.ImageGrab.grab
to take my screenshot. Then send it over using sockets and display it using opencv. But opencv works with numpy arrays. So I need to convert my screenshot into a np array. But Im having issues with encoding the array and then decoding it properly?

tiny panther
#

You can just send the image as a bytearray or byte string, as well with the shape of it, so you can load it from the buffer on the recieving end, and then reshape it accordingly

#

numpy supports np.array.tobytes and np.frombuffer to go between the two, but you'd have to specify the datatype when loading it from the buffer

#

And when converting to bytes, it doesn't preserve the shape, so loading from buffer always results in a 1d array, you'd have to reshape to a 3d or 4d array (depending on the image format)

Say I want to port forward my socket server. Is there a easy way to do this on mac. Im using Visual Studio btw.

steady horizon
waxen cradle
steady horizon
#

what is your binding function

#

i mean what IP are you assigning

#

in socket.bind

waxen cradle
#

Yea

#

Its just localhost

steady horizon
#

and the port number?

waxen cradle
#

65432

steady horizon
#

try
gethostbyname(gethostname())

#

instead of "localhost"

waxen cradle
#

Alright, give me a sec

steady horizon
#

these are two functions inside the socket module

waxen cradle
steady horizon
#

print it out
it should be a global IPv4 on Windows 10 machines

waxen cradle
#

I got "127.0.0.1", which I believe is the localhost

steady horizon
#

Really? Well that's unfortunate. Try using this script:

from json import loads
from urllib.request import urlopen
with urlopen("http://ipinfo.io/json/") as response:
    print(loads(response.read().decode())["ip"])

to get the IP.

waxen cradle
#

Do I create new file and run it?

steady horizon
#

If you want to.

waxen cradle
#

In the virtual machine

steady horizon
#

Yeah, you could.

waxen cradle
#

Alright give me sec

steady horizon
#

And just save it somewhere.

#

I mean, save it in your client file.

waxen cradle
#

Got this "54.167.60.102"

#

Only issue is that I dont think the port has been forwarded

turbid zenith
steady horizon
#

I use urllib since it is a standard library and it doesn't require you to pip install requests.

turbid zenith
#

I think requests is a standart library

steady horizon
#

Like honestly if you don't want to use requests just use urllib. They're the same except urllib is a standard library and you might need to import or do more stuff, just like how I did from json import loads to load the JSON of the response.

steady horizon
turbid zenith
#

I never installed it and I allways have it

#

idk if maybe a third party program installs it for me or something

waxen cradle
steady horizon
#

Maybe another library you use has required requests.

waxen cradle
#

Im only using threading and sockets

steady horizon
#

from there, there should be a login possibly and port forwarding is probably at advance settings

#

I tried ipconfig, but this is a bash terminal

Okay so I've read a bit on the internet and it seems as though PythonAnywhere doesn't allow using custom raw sockets like that. It supports WSGI so you can make a web app / API and communicate data like that.

waxen cradle
#

I just read that to

steady horizon
#

Do you think you can do that or do you want to give other hosts a try? I don't know any other hosts that can host socket applications like this.

waxen cradle

But im not going to go through the trouble of making that just for a socket

Thanks so much for your help though

steady horizon

prisma cobalt
#

@waxen cradle you can port forward your own network and host yourself you know

waxen cradle
#

I just wish I could port forward on my mac

#

But nothing works

prisma cobalt
#

your mac or your network?

because it is different

#

what router do you have?

#

they should ahve a guide on port forwarding if they support it

Let me check

#

prisma cobalt
#

@waxen cradle try this ip in the address bar

I actually im literally trying that right now, but it just doesnt load.

#

these are the two port forwarding guides they offer

waxen cradle
#

Let me try them

cedar forum
#

the automating way of doing port forwarding is doing the opposite

#

it's called hole punching

#

basically you have a server with a public static IP, you connect to that server and maintain a connection from the port you want to forward and then use that socket to communicate as if it were a port

#

it's how discord voice calls work

yeah you have to go through a central server

#

it's how stuff like ngrok works

#

generally I'd assume it is not on residential networks

#

it's probably situated on servers on the public facing internet with no need for port forwarding since there is no NAT

#

yes, generally your connection is to one server which the connects to the decentralised network

#

my understanding of crypto is limited though and I don't think it's a smart use of technology in a lot of cases
