It works for python 3.x after you change the print and using encode() and decode() on the strings

That clears my lot of doubts :)

Hey change localhost to the ip address for example
host = ‘localhost’;
to host = ‘192.168.4.33’; this being the ip address

Both protocols, Telnet and SSH work on TCP.

I’m getting the same error here, any advice?

On windows telnet I get this error: ‘Could not open connection to the host, on port (tried lots), connect failed…’
with ncat I get: ‘ An existing connection was forcibly closed by the remote host. .’

and with putty I get: ‘Network error: connection refused’
I’m confused…

Also, I went through your tcp socket tutorial, and that all worked correctly. Any help much appreciated.

Thank a lot!!! It works !!

You’re a good one!!! Thank again!!!

the last print statement should be

print (‘Message[‘ + addr[0] + ‘:’ + str(addr[1]) + ‘] – ‘ + data.strip().decode(“utf-8”))

it works!!! :)

But in this Server has other problem@@ I’m so sorry, because i’m a newbie

Simple udp socket server

import socket
import sys

HOST = ” # Symbolic name meaning all available interfaces
PORT = 8888 # Arbitrary non-privileged port

# Datagram (udp) socket
try :
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
print (‘Socket created’)
except socket.error as msg :
print (‘Failed to create socket. Error Code : ‘ + str(msg[0]) + ‘ Message ‘ + msg[1])
sys.exit()

# Bind socket to local host and port
try:
s.bind((HOST, PORT))
except socket.error as msg:
print (‘Bind failed. Error Code : ‘ + str(msg[0]) + ‘ Message ‘ + msg[1])
sys.exit()

print (‘Socket bind complete’)

#now keep talking with the client
while 1:
# receive data from client (data, addr)
d = s.recvfrom(1024)
data = d[0]
addr = d[1]

if not data:
break

reply = ‘OK…’ + data.decode(“utf-8”)

s.sendto(reply.encode(“utf-8”) , addr)
print (‘Message[‘ + addr[0] + ‘:’ + str(addr[1]) + ‘] – ‘ + data.strip())

s.close()

this should work

I change it :

import socket #for sockets
import sys #for exit

# create dgram udp socket
try:
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
except socket.error:
print (‘Failed to create socket’)
sys.exit()

host = ‘localhost’;
port = 8888;

while(1) :
msg = input(‘Enter message to send : ‘)
try :
#Set the whole string
s.sendto((msg, (host, port)))

# receive data from client (data, addr)
d = s.recvfrom(1024)
reply = d[0]
addr = d[1]

print (‘Server reply : ‘ + reply)

except (socket.error, msg):
print (‘Error Code : ‘ + str(msg[0]) + ‘ Message ‘ + msg[1])
sys.exit()

is that true?? but it doesn’t work @Silver Moon
