serv.login()
with serv as ftp, open(file_path, 'rb') as file:

ok for the people who lost braincells from this i am sorry i thought that the storbinary method was downloading files not uploading them

so the error it gave me was because it didnt find the file i was trying to get

because on an ordinary network, its required for devices from the outside to connect to a specific device on the inside

exactly

trim moth Mar 28, 2021, 2:59 PM

Yeah

prisma cobalt Mar 28, 2021, 2:59 PM

but to connect from other networks you need your public ip which, with a phone, is impossible to use since it changes

So I need a global ip from a router with the desired port forwarded and then run the socket server

#

Am I right?

yeah pretty much

trim moth Mar 28, 2021, 3:01 PM

#

What's other than the pretty much part which is left?

prisma cobalt Mar 28, 2021, 3:01 PM

nothing much, its just the port forwarding is usually something people need help with the first few times and its a "public" ip not global

trim moth Mar 28, 2021, 3:01 PM

Oh, got it

#

Public ip

prisma cobalt Mar 28, 2021, 3:01 PM

Then is it possible for a friend from 700 kms. away connect to a server running on my pc with the appropriate client file and chat with me?

my only suggestion now would be to get a mini hdmi cable and plug it into a moniter to see whats happening (you dont need a keyboard or mouse)

#

and even then that might not give any results

#

it might just say "not connecting" or something

ember ledge Mar 29, 2021, 9:21 PM

yeah I might have to. if that doesn't work then i'll just have to buy another pi zero

it depends on what msg app are you making,
every cloud is nice for its scalability

you can start with free tier and use a simple unix machine with public addres
and you can scale it to make it as big as you want

should be sufficient

so every month id get another ip?

i feel like im being stupid here

ember ledge Mar 30, 2021, 8:13 PM

#

checking

#

#

you get every month 750 hours of instance

#

and if you have more than 1 istance

#

then totally you will use faster those 750 hourrs

#

bc 2 instances in a month use 24 hours a day x number of days

#

so if u have 1 instance of ec2

#

u use 24 h and in march x 31 days = 744 hours

#

so its freee

#

and april comes in

#

and you have new 750 hours in aprill to spend xd

prisma cobalt Mar 30, 2021, 8:15 PM

lone haven Mar 31, 2021, 7:18 PM

#

modern edge specific request or response?

that request is getting send everytime the page is loaded

modern edge Mar 31, 2021, 7:21 PM

#

so you want to make a program which sends a request to a server every 30 minutes and store the header content of the response sent back by the server in a variable right?

lone haven Mar 31, 2021, 7:23 PM

#

yup exactly

#

what I wanna do

#

I'm not very good at programming so if you can help me a little bit that can help me a lot @modern edge

modern edge Mar 31, 2021, 7:24 PM

#

lone haven Is it possible to make a program that watches a specific request of a server eve...

yes it is possible to make such a program. I can help you but you have to write the code yourself obv. I cannot write it for you

#

use the requests library python. Take a look at this https://www.geeksforgeeks.org/response-headers-python-requests/

#

if i have any problems can I ask you in discord dms?

I asked that question before but no one answered, so ill ask again.
Is it secure to forward a port for my python application?
I have no idea how to write secure code (i would love to know how tho)
and i don't want a skid somewhere to get in my router and mess up my computer 'n' stuff.

prisma cobalt Mar 31, 2021, 9:17 PM

velvet lichen I asked that question before but no one answered, so ill ask again. Is it secure...

closed port: packet bounces off

hi

modern edge Apr 1, 2021, 2:13 AM

#

velvet lichen I asked that question before but no one answered, so ill ask again. Is it secure...

You can whitelist IPs. So only whitelisted IPs can connect to your socket server, so you will have no problems there. Use a port which is not already forwarded and used. And I have a question of my own : How will you forward the port? I tried many times myself to forward the port in my router but couldn't do it

shy island Apr 1, 2021, 4:16 AM

#

Hm

gray sage Apr 1, 2021, 5:08 AM

#

I needed a module, which is like the net module of js, for IPC connections. Anyone knows?

modern edge You can whitelist IPs. So only whitelisted IPs can connect to your socket server...

ah i see. well ill now i know. about your question: through my router's panel. like what i mean is you just enter the default gateway into some web browser and then you do magic 'n' stuff

ohk. I tried router forwarding many times but didn't work for me. Anyway good luck!!

#

thanks you.

weary silo Apr 1, 2021, 2:26 PM

#

velvet lichen I asked that question before but no one answered, so ill ask again. Is it secure...

depends how the setup is

#

if you just NAT your port then no its not secure at all

#

since you expose it to the internet

#

you should add something like a geoip filter and a reverse proxy

#

that should make it better

velvet lichen Apr 1, 2021, 2:31 PM

#

I didn't understand 99.9% of what you said... I'm not good at networking as you can see. Still learning tho

weary silo Apr 1, 2021, 2:32 PM

#

you have a public ip and a local on

#

you NAT your public one to your local one so the traffic gets redirected

velvet lichen Apr 1, 2021, 2:33 PM

#

ok

weary silo Apr 1, 2021, 2:33 PM

#

by doing your service is visible to the whole internet

#

and vulnerable

#

thats why you add something like a country/region filter

velvet lichen Apr 1, 2021, 2:33 PM

#

oh.

weary silo Apr 1, 2021, 2:33 PM

#

so only specific regions have access to the service

#

you also should put a reverse proxy infront of your service

velvet lichen Apr 1, 2021, 2:34 PM

#

do i do that in the code or router takes care of that?

weary silo Apr 1, 2021, 2:34 PM

#

since it adds a layer of security

#

firewall/router is for NAT

velvet lichen Apr 1, 2021, 2:34 PM

#

oh.

weary silo Apr 1, 2021, 2:34 PM

#

reverse proxy is just a program/service itself

#

like haproxy

#

or nginx

velvet lichen Apr 1, 2021, 2:34 PM

anyway. ill add a geo filter or whatever you call it. i need to look into that

weary silo Apr 1, 2021, 2:36 PM

yeah geoip filter

velvet lichen Apr 1, 2021, 2:36 PM

#

@weary silo

weary silo Apr 1, 2021, 2:38 PM

you should look into hosting

#

and just host your app on aws/heroku/azure etc

they have free tiers

#

its just not secure doing that

velvet lichen Apr 1, 2021, 2:39 PM

#

so they have servers that i can host crep on for free?

weary silo Apr 1, 2021, 2:39 PM

aws has a free tier yeah

it allows outbound connections and stuff?

#

@reef wigeon i cannot join a call, i think before looking at multi-processing you will want to first start with a single running instance of a lobby with clients connected. websockets could be an attractive option, since the connection is duplexed( i.e server can send on same connection that client connects on). https://github.com/codemation/easyrpc - can make setting this up pretty easy, but also allow for frequent client -> server -> client communication.

trim moth Apr 3, 2021, 8:02 AM

#

lol I've spent days on this thing, we can connect to any machine in the world, by running python socket servers and clients on appropriate machines

#

But

#

The thing is, the port of the host machine that your client is connecting to, must be forwarded on the host

#

If you manage that, you can connect to any machine to create things like TCP chat, a reverse shell on the host, and much more I might not even know of

I am trying to get a socket connection over the internet, I made a client.py and server.py scripts and they worked locally, I then switched the ip on the client side to my public ip and then set up port forwarding to my pc (which has a static ip), but the connection is still not happening, and using https://www.yougetsignal.com/tools/open-ports/ , I see that the port isn't even open, any ideas?

Open Port Check Tool - Test Port Forwarding on Your Router

The port forwarding tester is a utility used to identify your external IP address and detect open ports on your connection. This tool is useful for finding out if your port forwarding is setup correctly or if your server applications are being blocked by a firewall.

#

server.py

import time, socket, sys
 
new_socket = socket.socket()
 
port = 8080
 
new_socket.bind(("0.0.0.0", port))
print("Binding successful!")
 
name = input('Enter Username: ')
 
new_socket.listen(1) 

conn, add = new_socket.accept()

print("Received connection from ", add[0])
print('Connection Established. Connected From: ',add[0])

client.py

import time, socket, sys
 
socket_server = socket.socket()
server_host = socket.gethostname()
ip = socket.gethostbyname(server_host)
sport = 8080
 
server_host = "publicIPaddress"

name = input('Enter Username: ')

socket_server.connect((server_host, sport))

storm saffron Apr 5, 2021, 12:53 AM

encrypted tcp session is possible?

trim moth Apr 5, 2021, 5:00 AM

#

@next sapphire 8080 isn't a reserved or a important port right?

#

Like usually ports above 10k are suggested for such stuff

#

The most commonly used example is assigning port 8080 for a web server. To get traffic to this web server, you would need to append the port number to the end of the domain name like http://websitename.com:8080. Note that using port 8080 is not reserved for secondary web servers.

#

Copied from google lmao

#

Try forwarding some other port higher than 10k

When you open TCP connection it dies after some time when there are no packets on line. Despite of packet messages you should keep your connection by sending packets from clients to server which literally means "don't close the connection, I am still here"

Many people come here and ask why connecting to a server script using a public IP doesn't work. The main reason is that port forwarding hasn't been implemented on the server network.

What is port forwarding?
When you try to connect to a network, your connection is received by the networks router. Your router understands that these packets need to go to a device on your network but it doesn't know which device to send them to. This is where port forwarding comes in! When you set up port forwarding, you're creating a set of rules that tells your router to forward any packet it comes across on port {configurable port number here} to a specific device on your network. This allows direct communication between an outside source and a specific device on the network.

How do you set it up?
You need to find the default gateway IP first. You can do this by launching command prompt (cmd) and typing "ipconfig", then simply locate the default gateway entry. It may look something like: 192.168.1.254 but it might not be. Copy this IP into a URL bar of a web browser to access your router manager. Once there, you need to locate the "Port Forwarding Settings", bear in mind this could be under "Advanced Settings" if it doesn't appear on the main page. Once you've got that page open, you need to "add a new rule". This should allow you to enter a specific port number (or range of ports) and also a local IP of a device on your network. Once you've confirmed this, all packets sent to the public IP with that port number will be forwarded to that device.

If after a few days/weeks the script stops working out of nowhere, check out this (its possible your IP changed automagically):

prisma cobalt Apr 6, 2021, 10:44 AM

#

Potential problem (and solution):
After a few days or weeks, your client script might suddenly stop connecting to the server, this is most commonly found on home networks. This is because the public IP of the server's network is a "dynamic" IP address which is frequently changed by the ISP (internet service provider) to make full efficiency of the pool of IP's they can distribute. You have two options here, you could pay for a "static" IP from your ISP OR you could use a hosting service (which offers a static IP) to host your server script for you.

Hosting Services
There are a few hosting service that you can use to host your script for you. This allows you to set it up once and not worry about it, it also means you don't have to keep a device on your network running permanently since the hosting service is doing it for you
Free Options: (if anyone knows of any more simply tell me and i'll update it)
Amazon AWS servers - free tier
~~Heroku~~ not anymore

Sorry if this is the wrong place:
I have some code that reads from large files on a windows server, but when i time it over the network and on the server itself, i see that it reads faster over the network. Which confuses me, as shouldnt network reading add some overhead/latency then reading directly?

sometimes network transfer could be fast too lmao, I made file transferring client-server which moves files on the same device when on localhost at like 350-400 mbps while moving files through OS never goes that fast, but that's only for like moving files from one device to other tho, otherwise it's like 6-7 mbps

lol yaa .. but im just trying to squeak out more performance. Its for a larger project that loads up thousands of files and it takes minutes to run, so i was hoping to off load that loading to the server itself to speed it up

trim moth Apr 6, 2021, 1:03 PM

Threading might help you speeding things up since what you're doing is a io bound operation ig

tried that, it helps, still takes minutes

prisma cobalt Apr 6, 2021, 4:26 PM

#

i assume your actually changing the publicIPaddress to the actual ip

next sapphire Apr 6, 2021, 4:34 PM

#

Yes I am

#

To the ip that the google search gives me

#

I’m thinking either that is wrong for some reason, or there’s a firewall still blocking it maybe? Stopping my antivirus didn’t help however

prisma cobalt Apr 6, 2021, 4:37 PM

#

@next sapphire do you get the option to enter username on both scripts?

next sapphire Apr 6, 2021, 4:37 PM

#

Yes I do, then they both hang

#

Also if I switch the public ip on the client to the local ip of the server it works

prisma cobalt Apr 6, 2021, 4:38 PM

#

hmm, its a probably port forwarding or the firewall as you mentioned

next sapphire Apr 6, 2021, 4:39 PM

#

That’s what I figured, I don’t know exactly how test port forwarding, but I ran the server and checked if the port was open and it was closed

prisma cobalt Apr 6, 2021, 4:41 PM

#

i see a problem with your code but it may or may not effect how it works

#

your asking for the username after binding in the server and before listning
change it to ask for username before both

#

actually your acting like the server script is a client which is weird as well

next sapphire Apr 6, 2021, 4:43 PM

#

Do you mean because it has a username? I had it so the server could send messages like the clients

#

This was just some test code I found and I’m trying to get it to work over the internet before I change it up

prisma cobalt Apr 6, 2021, 4:44 PM

#

can i write you a client and server script for you to run and test

#

?

next sapphire Apr 6, 2021, 4:44 PM

yeah definitely that would be helpful!

prisma cobalt Apr 6, 2021, 4:46 PM

server:

import socket

sock = socket.socket()
sock.bind(("0.0.0.0", 8080))

sock.listen(1)
conn, add = new_socket.accept()

print("Received connection from ", add[0])

client:

import socket

sock = socket.socket()
sock.connect(("publicIPhere", 8080))
print("connected")
