I tried as hard is a could to create (or adapt) the following codes so that i can download a file (with any extension) from a server to the client in a new directory (to be more explicit, the client receives the file,downloads it in a new directory). I leave you the initial codes without my modifications,such in that way your changes won't be necessarly easier, but will help me where and why i'm wrong. Pay attention that codes are wrote in python and Linux OS(that's for directory paths). And do not forgot that i'm really new in Linux and Python. I tried many many variants but with many errors. Any help will be apreciated:).
**#CLIENT**
import socket # Import socket module
s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
port = 60000 # Reserve a port for your service.
s.connect((host, port))
s.send("Hello server!")
with open('received_file', 'wb') as f:
print 'file opened'
while True:
print('receiving data...')
data = s.recv(1024)
print('data=%s', (data))
if not data:
break
# write data to a file
f.write(data)
f.close()
print('Successfully get the file')
s.close()
print('connection closed')
**#SERVER**

s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
s.bind((host, port)) # Bind to the port
s.listen(5) # Now wait for client connection.
print 'Server listening....'
while True:
conn, addr = s.accept() # Establish connection with client.
print 'Got connection from', addr
data = conn.recv(1024)

I'm trying to send one file which is txt file through a python socket. I want the txt file which is received by the client keeps its extension which is txt.
Here is my server's side:
import socket
port = 50000
s = socket.socket()
host = "localhost"
s.bind((host, port))
s.listen(5)
print 'Server listening....'
while True:
conn, addr = s.accept()
print 'Got connection from', addr
data = conn.recv(1024)
print('Server received', repr(data))
filename='file.txt'
f = open(filename,'rb')
while (f):
conn.send(filename)
f.close()
print('Done sending')
conn.close()
Here is my client's side:
import socket # Import socket module
s = socket.socket() # Create a socket object
host = "localhost" #Ip address that the TCPServer is there
port = 50000 # Reserve a port for your service every new transfer wants a new port or you must wait.
s.connect((host, port))
s.send("Hello server!")
while True:
print('receiving the file...')
data = s.recv()
if not data:
break
print('Successfully get the file')
s.close()
print('connection closed')
All I found online is either modifying this file or sending a text in that file.
In the code below I've tried to send an image using the python socket module in one machine to another machine. So I have 2 files: client.py and Server.py
as I figured it out the problem is when I read the image(as bytes) at the client machine and then the server tries to receive the file, at that moment when sending process is done before the receiving process then the error below occurs at line 13 of the client code:
BrokenPipeError: [Errno 32] Broken pipe
I want to find out what this error is and why does it occur in my code.
Server.py
import socket
host = '192.168.1.35'
port = 5000
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((host,port))
s.listen(1)
while True:
conn , addr = s.accept()
data = conn.recv(1024)
with open(r"C:\Users\master\Desktop\music.jpg",'wb') as f:
f.write(data)
# conn.send(b'done')
data = conn.recv(1024)
if not data:
break
conn.send(b'done')
conn.send(b'done')
conn.close()
s.close()
Client.py
import socket
def main():
HOST = '192.168.1.35'
PORT = 5000
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
f = open('/home/taha/Desktop/f.jpg','rb')
data = f.read()
s.sendfile(f)
if s.recv(1024) == b'done':
f.close()
s.close()
if __name__ == '__main__':
main()
You are closing the server connection before the client read the “done”
I am using locust.io for the first time. I want to access a file from a virtual machine which i have created using a get request in locust.io. I want to then simulate multiple users for this request. Is this possible using locust.io?
Basically the code below is what I want to replicate using locust.io for multiple users.
This is my code for a single client and server using sockets.
#server.py
import socket
port = 3335
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
#host = socket.gethostname()
s.bind(('',port))
s.listen(5)
print("server Ready")
while True:
conn,addr = s.accept()
print("connection received from ",addr)
data = conn.recv(2048)
#print("server received",repr(data))
filename=data.decode()
f=open(filename,'rb')
l=f.read(1024)
while(l):
conn.send(l)
print('sent',repr(l))
l=f.read(1024)
f.close()
print('done sending')
#conn.send('thankyou'.encode())
conn.close()
#client.py
import socket
port = 3335
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
host = input("Enter the ip address of server")
s.connect((host,port))
file = input("Enter the filename")
s.send(file.encode())
while True:
print("receiving data")
data = s.recv(1024)
print("data = ",(data))
if not data:
break
print("successful")
s.close()
print("connection closed")
I'm new to python and this time I want to send a file between two VMs, first of all, the VMs are configured with NAT Network, both VMs can ping each other. The codes are the following:
Server side:
#server.py
import socket # Import socket module
port = 60000 # Reserve a port for your service.
s = socket.socket() # Create a socket object
host = socket.gethostname() # Get local machine name
# s.bind((host, port)) # Bind to the port
s.bind(('', port))
s.listen(5) # Now wait for client connection.
print 'Server listening....'
while True:
conn, addr = s.accept() # Establish connection with client.
print 'Got connection from', addr
data = conn.recv(1024)
print('Server received', repr(data))
filename='runbonesi.py'
f = open(filename,'rb')
l = f.read(1024)
while (l):
conn.send(l)
print('Sent ',repr(l))
l = f.read(1024)
f.close()
print('Done sending')
conn.shutdown(socket.SHUT_WR)
print conn.recv(1024)
conn.close()
client side:
#client.py
import socket # Import socket module
s = socket.socket() # Create a socket object
#host = socket.gethostname() # Get local machine name
host = '10.0.2.15'
port = 60000 # Reserve a port for your service.
s.connect((host, port))
with open('received_file', 'wb') as f:
print 'file opened'
while True:
print('receiving data...')
data = s.recv(1024)
print('data=%s', (data))
if not data:
break
# write data to a file
f.write(data)
f.close()
print('Successfully get the file')
s.close()
print('connection closed')
The results can be seen in the following pictures:
Server side:
result on server
Client side:
result on client
The problem is, the client didn't receive the file as .py format, it only received as txt files. Please help me resolve this issue.
Thank you.
After s.connect((host, port)) in the client script you have to write s.send(...) with 'hello', for example. You also forgot to write the file extension '.py' in with open(...) (only if you want to save the file as Python script!). And you also have to add s.send(...) before you close the connection on the client side. 😉
Greetings and apologies in advance if it looks a real novice question. I am new to python, or programming for that matter. I am writing a code that sends data from client to server. The data I need to send is from an csv file, which has around 10,000 rows. Currently I am sending the data in a large buffer as a whole, but I would prefer to send it row by row and also receive it the same way. I am not sure if I should use the split() function or there are any better ways to do the same thing.
The client...
import socket
HOST = 'server IP'
PORT = 42050
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
f = open('csvfile.csv', 'rb')
l = f.read(409600)
while True:
print l
s.send(l)
break
f.close()
print "Done Sending"
s.close()
The server...
import socket
HOST = 'local IP'
PORT = 42050
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
print "Server running", HOST, PORT
s.listen(5)
conn, addr = s.accept()
print'Connected by', addr
while True:
data = conn.recv(409600)
print repr(data)
if not data: break
print "Done Receiving"
conn.close()
Thanks in advance for the help.
im not sure what your question actually is ... but its pretty easy to send and receive lines
#client.py
for line in open("my.csv"):
s.send(line)
#server.py
def read_line(sock):
return "".join(iter(lambda:sock.recv(1),"\n"))
iter(lambda:sock.recv(1),"\n")
is essentially the same as
result = ""
while not result.endswith("\n"): result += sock.recv(1)
