HI I want to have my ip and port as user input in my server but i get some errors i cant handle please help me ...
import socket
serversocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = input("Enter The Server Ip: ")
port = input("Enter The Server Port: ")
serversocket.bind((host, port))
serversocket.listen(10)
while True :
clientsocket, address = serversocket.accept()
print("Received Connection From %s" % str(address))
message = 'Connection Established' + "\r\n"
clientsocket.send(message.encode("ascii"))
clientsocket.close()
Error :
line 11, in <module>
serversocket.bind((host, port)) # Host will be replaced with IP, if changed and not running on host
TypeError: an integer is required (got type str)
or some times i get :
TypeError: an integer is required (got type str)
input() gives you port as string but socket needs it as integer
port = int(port)

I am trying to simply send a list from one computer to another.
I have my server set up on one computer, where the IP address is 192.168.0.101
The code for the server:
import socket
import pickle
import time
import errno
HEADERSIZE = 20
HOST = socket.gethostbyname(socket.gethostname())
PORT = 65432
print(HOST)
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
s.listen(10)
while True:
conn, adrs = s.accept()
print(f"Connection with {adrs} has been established")
conn.setblocking(1)
try:
data = conn.recv(HEADERSIZE)
if not data:
print("connection closed")
conn.close()
break
else:
print("Received %d bytes: '%s'" % (len(data), pickle.loads(data)))
except socket.error as e:
if e.args[0] == errno.EWOULDBLOCK:
print('EWOULDBLOCK')
time.sleep(1) # short delay, no tight loops
else:
print(e)
break
The client is on another computer. The code:
import socket
import pickle
HOST = '192.168.0.101'
PORT = 65432
def send_data(list):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.settimeout(10)
print(".")
print(s.connect_ex((HOST, PORT)))
print(".")
data = pickle.dumps(list)
print(len(data))
s.send(data)
s.close()
send_data([1,1,1])
The outputted error number of connect_ex is 10035. I read a lot about the error, but all I found was about the server side. To me, it looks like the problem is with the client and that it is unable to make a connection to 192.168.0.101. But then, I don't understand why the error I get is about non-blocking.
What is it that I am doing wrong that I am unable to send data?
First of all, how user207421 suggested, change the timeout to a longer duration.
Also, as stated here Socket Programming in Python raising error socket.error:< [Errno 10060] A connection attempt failed I was trying to run my server and connect to a private IP address.
The fix is: on the server side, in the s.bind, to leave the host part empty
HOST = ''
PORT = 65432
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind((HOST, PORT))
And on the client side, use the public IP of the PC where the server is running (I got it from ip4.me)
HOST = 'THE PUBLIC IP' #not going to write it
PORT = 65432
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((host, PORT))
I just copied this code for a client/server example:
http://www.bogotobogo.com/python/python_network_programming_server_client.php
and when I run the code I get this error:
OSError: [Errno 99] Cannot assign requested address
Server:
# server.py
import socket
import time
# create a socket object
serversocket = socket.socket(
socket.AF_INET, socket.SOCK_STREAM)
# get local machine name
host = socket.gethostname()
port = 9999
# bind to the port
serversocket.bind((host, port))
# queue up to 5 requests
serversocket.listen(5)
while True:
# establish a connection
clientsocket,addr = serversocket.accept()
print("Got a connection from %s" % str(addr))
currentTime = time.ctime(time.time()) + "\r\n"
clientsocket.send(currentTime.encode('ascii'))
clientsocket.close()
Client:
# client.py
import socket
# create a socket object
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# get local machine name
host = socket.gethostname()
port = 9999
# connection to hostname on the port.
s.connect((host, port))
# Receive no more than 1024 bytes
tm = s.recv(1024)
s.close()
print("The time got from the server is %s" % tm.decode('ascii'))
Replace host = socket.gethostname() with host = '127.0.0.1' and it should work.
Check this
Hope this wil help :)
i made a python listener(server) on my vps
but when i give the server and client the ip addreess of vps and port 8585
this error shows:
error :
socket.error: [Errno 32] Broken pipe
i use python version 2 in vps
i use python version 3 in my PC
my server code :
import socket
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
ip = raw_input("ip : ")
ip = str(ip)
port = raw_input("port : ")
port = int(port)
s.bind((ip,port))
s.listen(5)
while True:
c, addr = s.accept()
s.send("welcome !")
print (addr, "connected.")`
client :
import socket
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
HOST = input("HOST : ")
HOST = str(HOST)
PORT = input("PORT : ")
PORT = int(PORT)
s.connect((HOST,PORT))
buff = 1024
data = s.recv(buff)
print(data)`
In the server you have:
c, addr = s.accept()
s.send("welcome !")
You must do the send on the connected socket to the client and not on the listener socket, i.e. it should be c.send instead of s.send.
#!/usr/bin/env python
import socket
clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientsocket.connect(('192.168.1.123', 5162))
clientsocket.send('getval.1')
clientsocket.close
clientsocket.bind(('192.168.1.124', 5163))
clientsocket.listen(1)
while True:
connection, address=clientsocket.accept()
value=connection.recv(1024)
print value
I'm trying to get python to send a message to the server, and in return the server responds. Yet when I execute this code it gives me
Socket.error: [Errno 10022] An invalid argument was supplied
It seems you wrote a mixed code of server and client
Here a simple sample of codes for socket programming the first on server side and the second on client
Server side code:
# server.py
import socket
import time
# create a socket object
serversocket = socket.socket(
socket.AF_INET, socket.SOCK_STREAM)
# get local machine name
host = socket.gethostname()
port = 9999
# bind to the port
serversocket.bind((host, port))
# queue up to 5 requests
serversocket.listen(5)
while True:
# establish a connection
clientsocket,addr = serversocket.accept()
print("Got a connection from %s" % str(addr))
currentTime = time.ctime(time.time()) + "\r\n"
clientsocket.send(currentTime.encode('ascii'))
clientsocket.close()
and now the client
# client.py
import socket
# create a socket object
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
# get local machine name
host = socket.gethostname()
port = 9999
# connection to hostname on the port.
s.connect((host, port))
# Receive no more than 1024 bytes
tm = s.recv(1024)
s.close()
print("The time got from the server is %s" % tm.decode('ascii'))
The server simply remained listened for any client and when it finds out a new connection it returns current datetime and closes the client connection
I am trying to create a basic instant message program that uses a p2p (peer-to-peer) connection so it will not need a server. I am pretty sure nothing is wrong, but every time I run the client program I have created, I get this error:
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
NameError: global name 'SOL_SOCKET' is not defined
Here is the program:
import socket
def Receiver():
# Create socket that supports IPv4, TCP Protocol
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "Socket created."
# Requests for IP of host (DNS)
dns = "localhost"
HOST = ''
PORT = 25395
try:
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
except socket.error as serror:
print "socket error"
s.bind((HOST, PORT)) # Listens on all interfaces...
print 'Listening on port 25565'
s.listen(True) # Listen on the newly created socket...
conn, addr = s.accept()
print 'Connected in port 25565'
data = conn.recv(1024)
print data
s.close()
def Sender():
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
dns = "localhost"
HOST = socket.gethostbyname(dns)
port = 25565
# Connect to server
s.connect((host,port))
print "Socket connected to " + dns + " on IP " + host
# Assign message to be sent to server to a variable
message = raw_input("Message to be sent to server: ")
#Send the actual message to server
s.sendall(message)
print "Message sent successfully"
s.close()
input = raw_input('S is send, R is receive: ')
if input == 's':
Sender()
if input == 'r':
Receiver()
I have tried removing s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1) but it tells me that I cannot use 2 sockets on the same port when there isn't 2 sockets using the same port.
In your code:
s.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
do like:
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
# ^^^^ added ^^^
because you imported just socket, check following code pieces:
>>> import socket
>>> SOL_SOCKET
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'SOL_SOCKET' is not defined
>>> socket.SOL_SOCKET
1
