I have written a client and a server-side code to set a P2P type system with a server as a middleman to distribute a file to N clients.
I am getting this error OSError: [WinError 10022] An invalid argument was supplied in this chunk of my code on the server side
try:
for i in l:
print(i)
x = random.randint(0,N-1)
print(x,"Index")
serverSocketTCPRequest = serverSocketTCPList[x]
serverSocketTCPRequest.settimeout(2)
serverSocketTCPRequest.connect((i[0],i[1]))
serverSocketTCPRequest.send("SEND".encode())
serverSocketTCPRequest.send(str(chunkID).encode())
data = serverSocketTCPRequest.recv(1024)
serverSocketTCPRequest.close()
b = False
return data
except Exception as ex:
print(traceback.format_exc())
time.sleep(1)
# print(l)
pass
I am getting the following error:
Traceback (most recent call last):
File "d:\IITD\5th Sem\COL334\Assignment 2\server.py", line 149, in getChunks
serverSocketTCPRequest.connect((i[0],i[1]))

OSError: [WinError 10022] An invalid argument was supplied
My client side code for the same is
def handleTCP(client:Client):
global N
while(True):
try:
# print(clientList.index(client), client.clientSocketTCPRequest.getsockname())
client.clientSocketTCPRequest.listen(2*N)
client.clientSocketTCPRequest.settimeout(2)
connectionSocket, addr = client.clientSocketTCPRequest.accept()
print("Connected")
message = connectionSocket.recv(1024).decode()
if message.decode() == "SEND":
i = connectionSocket.recv(1024).decode()
connectionSocket.send(client.dict[int(i)])
connectionSocket.close()
elif message.decode() == "GET":
i = connectionSocket.recv(1024).decode()
client.dict[int(i)] = connectionSocket.recv(1024)
connectionSocket.close()
except Exception as ex:
template = "An exception of type {0} occurred. Arguments:\n{1!r}"
m = template.format(type(ex).__name__, ex.args)
print(m,client.clientSocketTCPRequest.getsockname())
# print(traceback.format_exc())
continue
I can't think of a reason this is occurring. The client side shows just a timeout error on each of the N ports.
I have attached the entire client and server side codes and the file I'm trying to send.

I am connecting, or trying to, MySQL and Python via PyCharm and I input the code that I was given and I am getting several errors that I am unable to resolve. Is there a pro out there that can assist?
Here is the code:
import mysql.connector
from mysql.connector import errorcode
config = {
"user": "movies_user",
"password": "popcorn",
"host": "127.0.0.1",
"database": "movies",
"raise on warnings": True
}
try:
db = mysql.connector.connect(**config)
print("\n Database user {} connected to MySQL on host {} with database {}".format(config["user"], config["host"],
config["database"]))
input("\n\n Press any key to continue...")
except mysql.connector as Error:
if err.errno == errorcode.ER_ACCESS_DENIED_ERROR:
print(" The supplied username or password are invalid")
elif err.errno == errorcode.ER_BAD_DB_ERROR:
print(" The supplied database does not exist")
else:
print(err)
finally:
db.close()
And here are the errors:

I feel like I have tried everything that I can possibly find on Google. Any help is much appreciated!
I have tried the above code and I have tried resolving the errors to no avail.
I'm trying to kick client from the server, and after that I get the follwing exception:
Exception in thread Thread-2 (__handle_client):
Traceback (most recent call last):
File "/Users/macbook/Desktop/Python Projects/Cars/Server/server.py", line 36, in __handle_client
message = client.recv(1024).decode(FORMAT)
OSError: [Errno 9] Bad file descriptor
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "/Library/Frameworks/Python.framework/Versions/3.10/lib/python3.10/threading.py", line 1009, in _bootstrap_inner

File "/Users/macbook/Desktop/Python Projects/Cars/Server/server.py", line 41, in __handle_client
client.send('You left the chat room'.encode(FORMAT))
OSError: [Errno 9] Bad file descriptor.
But when I use the exit function it is going well. Both using the __close_connection function.
This is my Code:
def __handle_client(self,client):
while True:
try:
message = client.recv(1024).decode(FORMAT)
if self.__handle_messsage(message,client) == True:
break
except:
client.send('You left the chat room'.encode(FORMAT))
self.__broadcast(f'{self.__clientnick[client]} has left the chat room!',)
del self.__clientnick[client]
client.close()
break
def __handle_messsage(self,message,client):
if message == '/exit':
exit_message = 'You have discinnected successfully.'
self.__close_connction(exit_message,client)
return True
if message.startswith('/kick'):
if self.__clientnick.get(client) == 'admin':
for check_client in self.__clientnick:
if self.__clientnick.get(check_client) == message[6:len(message)]:
kick_message = 'You have been kicket from the chat room.'
self.__close_connction(kick_message,check_client)
return True
else:
client.send('You are not admin!'.encode(FORMAT))
def __close_connection(self,message,client):
client.send(message.encode(FORMAT))
self.__broadcast(f'{self.__clientnick[client]} has left the chat room!',client)
del self.__clientnick[client]
client.close()
It seems that you already closed the connection when you did kick and that is why you get the exception. the second exception is when you try to send a message to the closed connection.
I am using Python3.7
I am trying to email an error in the except condition to the user if the code is not working and following is my code:
except Exception as e:
logging.basicConfig(filename='logfile.log',format='%(asctime)s %(message)s',filemode='w')
logger=logging.getLogger()
logger.setLevel(logging.ERROR)
logger.error(e)
print("ERROR MESSAGE",e)
MY_ADDRESS = '*****#gmail.com'
PASSWORD = '*******'
MY_ADDRESS1 = '****#gmail.com'
s = smtplib.SMTP(host='smtp.gmail.com', port=***)
s.starttls()
s.login(MY_ADDRESS, PASSWORD)
print("login")
msg = MIMEMultipart() # create a message
msg['From']=MY_ADDRESS
msg['To']=MY_ADDRESS1
msg['Subject']="ERROR MESSAGE"
message="ERROR"
msg.attach.as_string(MIMEText(e))
print("ERROR MAILED")
s.send_message(msg)
s.quit()
I want to send the error message in variable 'e' which is being printed
But I am unable to do so
Following is the error:
This is the error which i want to print and mail:

How do i send the error message being printed in variable 'e' by email to someone
THANK YOU
The logging module itself has smtp handler you can do something like this:
import logging
import logging.handlers
smtp_handler = logging.handlers.SMTPHandler(mailhost=("smtp.example.com", 25),
fromaddr="someone#something.com",
toaddrs="receiver#mail.com",
subject=u"ERROR IN YOURAPP!")
logger = logging.getLogger()
logger.addHandler(smtp_handler)
try:
raise Exception
except Exception as e:
logger.exception('Unhandled Exception')

when the network goes offline, the sockets throws error instead of reconnecting. It is reconnecting but not trying to achieve the connection. throws error in second or third attempt. Do I need to increase the wait time or is there anything which can be added to make sure the reconnect takes place

client.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)

address = (ip,port)
client.connect(address)

I want to return an error code when the following error gets raised:

But I'm currently having trouble catching the error raised.
try:

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect(hostname, username=user, password=remotepass)

chan = ssh.get_transport().open_session()
chan.exec_command(command)
codest = chan.recv_exit_status()

Resulting on this:

Any ideas?
Do
import socket
in the module where you do the exception handling.
To prevent this problem in the future, run pyflakes on all your source files. That will catch a lot of other errors as well.
