I am trying to create a simple "chat room" of the sort, where I do not know how many messages I will get from a client but my server will receive them all, display them and eventually respond. The problem is that when I click on the respond textbox, my code crashed. I am really unsure about where my problem lies and any help will work.

the easiest way is to make the chat room like a reverse shell .

I have a basic program where in a Tkinter window a user presses a button that generates a string in a listbox. Using a second send button, I want to transfer those strings through a socket server to a second client. The message printed to the console at the point of departure (client1) is a tuple, and it can be iterated through with a for loop to make it more legible i.e. each element is printed to a new line. Using a print function at the point of arrival (client2), the same tuple is produced, but trying to use a for loop on it iterates through each character in the group of strings, as opposed to each element of the tuple as desired.
This is client1:

receive_thread.start()
tkinter.mainloop()
As I said above, the msg variable in client2, the one that receives the message, is printed as a tuple but a for loop will iterate over each character of the strings contained.
Using the pickle module I received two separate errors.
When I pass .decode("utf-8) and then .loads() it says "Could not find MARK).
Without the .decode(), the error is "unpickling stack underflow".
My desired outcome is for each of the individual strings that arrive over the TCP socket to be added to the listbox in client2 on a new line, and without the ('', '') symbols.
Should I try to convert it to a .json object?
Or will another networking module produce better results?
I'm sorry about the length of code and the potentially obvious answer. Beginner to networking.
I am making a python chatroom application for school with a functioning clientside and serverside script. I am now adding multiple functionalities to the chatroom to make it easier to use, one of which is hopefully spam protection. Is there a way I can record how many messages per a certain measurement of time the client is sending and if they go over the maximum they are muted for a certain amount of time?

A way to do this is using the widget.unbind(sequence, funcid = None) method.
This, as the name suggests, deletes the bindings on w for a determined event.
Then you can use the tkinter built-in method root.after() to call a function that you create to rebind the button to the function.
But for this to work you need to bind the send_button using the .bind() method.
def rebind():
send_button.bind("<Button-1>", send)
send_button.bind("<Button-1>", send)
send_button.unbind("<Button-1>", funcid=None)
top.after(time in miliseconds, rebind)

Why is my Button's command executed immediately when I create the Button, and not when I click it? [duplicate]

Closed 4 years ago.
So today I've been working on a new GUI with tkinter and came across and issue with parsing a string from an entry into an int and I get this error.
Traceback (most recent call last):
File "/Users/g.shiner21/Desktop/Python/P2PFile/P2PFileServer.py", line 47, in <module>
bStartServer = Button(f1, text="Start Server", command=startServer(host))
File "/Users/g.shiner21/Desktop/Python/P2PFile/P2PFileServer.py", line 28, in startServer
intport = int(port)
ValueError: invalid literal for int() with base 10: ''
Here is the function,
def startServer(host):
port = ePort.get()
intport = int(port)
s = socket.socket()
s.bind((host, intport))
s.listen(4)
The most confusing part is that when I test something like this,
strTest = "10000"
intTest = int(strTest)
I get no errors. So I don't think I'm doing my parsing wrong. But at this point I'm not too sure. Any help would be greatly appreciated! :)
Edit: For those that it helps here is the full program(or at least what I have so far. I commented out the second part of it while I was building the GUI because I didn't want to have to deal with any interferences.

You get this error when the python can't cast the variable to int. make sure "port" is an integer and the try casting that to int. the second example works fine because your hard coding the value of input and it's an integer. You can update your function as follows:
def startServer(host):
try:
port = ePort.get()
intport = int(port)
s = socket.socket()
s.bind((host, intport))
s.listen(4)
except BaseException:
print('wrong entry')
I am trying to make a simple system to transfer a file from server to client.
I want to show the client a file open dialog using tkFileDialog.
The problem is when I run the client & server the dialog box gets opened in server rather than client. I thought about send the object of tkFileDialog via
con.send(str(tkFileDialog.askopenfilename(initialdir='~', title='Choose a text file/program')))
If someone could help me out with this it will be really helpful or if someone has a better idea to open server filesystem in client without ssh

The file dialog works only for the system that opens it. You can't use it to pick files on a remote system.
Was trying to make a chat application written in Python, but for some reasons I don't know, when the 1st client sends data, it works but the 2nd or other client can't receive it until the other client tries to send a message and it works fine...
Here's my code for the client:
from Tkinter import *
from PIL import ImageTk, Image
from socket import *
from threading import Thread, Lock
import time
'#Connect to Server'
shutdown = False
host = "127.0.0.1"
port = 0
server = ("127.0.0.1", 12345)
s = socket(AF_INET, SOCK_DGRAM)
s.bind((host, port))
s.setblocking(0)
global alias
def sendmsg():
msg = alias + " : " + chatEntry.get("0.0", END).strip() + "\n"
#chatLog.config(state=NORMAL)
#chatLog.insert(END, msg)
chatEntry.delete(1.0, END)
#chatLog.config(state=DISABLED)
s.sendto(msg, server)
def recvmsg(name, sock):
while not shutdown:
try:
while True:
data = sock.recv(1024)
chatLog.config(state=NORMAL)
chatLog.insert(END, str(data))
chatLog.config(state=DISABLED)
print str(data)
except:
pass
alias = raw_input("Alias ==> ")
root = Tk()
'#Create a window'
frame = Frame(root, width=600, height=450, bg="black")
frame.pack()
'#Create a chat log'
chatLog = Text(root, font=("Determination Sans", 12))
chatLog.insert(END, "Connecting..... \n")
chatLog.config(state=DISABLED)
chatLog.place(x=13, y=13, width=425, height=329)
'#Create list of friends online'
friendsList = Text(root)
friendsList.config(state=DISABLED)
friendsList.place(x=445, y=13, width=142, height=329)
'#Create an entry where you can enter your message'
chatEntry = Text(root)
chatEntry.place(x=13, y=349, width=425, height=96)
'#Create a send button'
btnLogin = Button(root, text="SEND", command=sendmsg)
btnLogin.place(x=445, y=349, width=142, height=96)
'#Set it fixed, not resizable......'
root.resizable(width=FALSE, height=FALSE)
root.wm_title("Chat - Underchat")
Thread(target=recvmsg, args=("RecvThread", s)).start()
root.mainloop()
And here's my code for the server:
from socket import *
import time
'#Put IP here...'
'#Put Socket here...'
host = "127.0.0.1"
port = 12345
clients = []
s = socket(AF_INET, SOCK_DGRAM)
s.bind((host, port))
'#Set Blocking to 0 so it will accept basically everything'
s.setblocking(0)
quitting = False
print "server started....."
while not quitting:
try:
'#Receive 1024 bytes of data... Its basically 1KB :P '
data, addr = s.recvfrom(1024)
if "Quit" in str(data):
'#Quit if a specified string was detected...'
quitting = True
if addr not in clients:
'#If a new client was found, add them to the clients list'
clients.append(addr)
print time.ctime(time.time()) + str(addr) + ": :" + str(data)
for client in clients:
'#Send the data to all clients... This is a groupchat afterall :3'
s.sendto(data, client)
except:
'#Try again if something goes wrong.....'
pass
'#Close the connection when out of the loop'
s.close()
So any ideas? Thanks
