cant establish connection with port using python app

I made a back door using pythonpicture of error message, and compiled it to an application (.exe) file on windows, using pyinstaller command,
the process works by using 2 files; 1 is malicious which stays on the target machine and the other one opens a shell on the attacker machine,, to gain control of the infected machine.
but while testing the malicious application on my windows environment ("it's my own machine so I have permission to test on it ") I saw that I was facing " win error 10060"
as far as I understand by the windows error message; it is saying it can't communicate with the attacker machine
(check the image and code to get a better idea of the problem .)
what can I do to avoid this ?

Problems while implementing file transfer with sockets in Python

I am learning Python right now, and try to write a small file transfer program. The following is my codes.
This is the server codes
import SocketServer
import commands, time
class MySockServer(SocketServer.BaseRequestHandler):
def recv_all(self,obj, msg_length, des_file):
while msg_length != 0:
if msg_length <= 1024:
print 'here3'
print msg_length
print type(msg_length)
data = obj.recv(msg_length)
print data
msg_length = 0
print 'here4'
break
else:
data = obj.recv(1024)
msg_length -= 1024
#print msg_length
des_file.write(data)
print 'here4'
return 'Done'
def handle(self):
print 'Got a new conn from', self.client_address
while True:
cmd = self.request.recv(1024)#receive data from client
print cmd
if not cmd:#deal with ctrl+c from client
print 'Lost connection'
break
CMD = cmd.split()
print CMD
option, filename, file_size = CMD[:3]
print option
print filename
print file_size
if option == 'put':
#client wants to upload file
f = file('temp/%s' % filename, 'wb')
print 'here'
write_to_file = self.recv_all(self.request, int(file_size), f)
print 'here1'
if write_to_file == 'Done':
f.close()
self.request.send('File uploading done')
if __name__ == '__main__':
h = '0.0.0.0'
p = 9002
s = SocketServer.ThreadingTCPServer((h,p),MySockServer)
s.serve_forever()
The client codes:
import socket, os
host,port = '192.168.73.11', 9002
c = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
c.connect((host,port))
while True:
user_input = raw_input('msg to send:: ').strip()
if len(user_input) == 0: continue
user_cmd = user_input.split()
if user_cmd[0] == 'put':
if len(user_cmd) == 2:
f = file(user_cmd[1], 'rb')
f_size = os.path.getsize(user_cmd[1])
print user_cmd[0], user_cmd[1], str(f_size)
c.send('%s %s %s ' % (user_cmd[0],user_cmd[1],f_size))
print 'going to send....'
c.sendall(f.read())
print c.recv(1024)
c.close()
I just inserted some prints into the codes to find where are the problems. I found that in the recv_all() function in server codes, the sentence 'data = obj.recv(msg_length)' in the 'if' part cannot work, but the sentence in the 'else' part works very well. Is there anyone can tell me why could this happen?
Thanks guys.

This is supposed to start printing the percentage downloaded of the file being downloaded once the file appears. What I am seeing is that the file appears and then moments later I get the output saying that it is 100% downloaded. I can't see exactly what I'm doing wrong here.

The problem was the fact that every time it checked the current downloaded data to the data that needed to be downloaded, it never updated the variables. So when the loop came around, it was comparing the same numbers until something. It was stuck in this loop and when something caused it to exit, I'm not sure what, it continued to the next line of code printing that it was finished downloading.

Python Script Name Not Defined

I am very new to Python. I was following a simple Python tutorial, but don't get the expected results.
After running the compiled executable on the client, the client shows up on my server. However, when I choose the client number (1), the python script is immediately exited and I get the following error when run on a remote Linux server:
Activating client: ('172.51.8.204', 18268)
Traceback (most recent call last):
File "xmulti_aeserver.py", line 207, in <module>
if nextcmd.startswith("download ") == True:
NameError: name 'nextcmd' is not defined
When run locally on a Windows server, the script does not exit, but the server disconnects the client as such:
Activating client: ('192.168.1.104', 26042)
Client disconnected... ('192.168.1.104', 26042)
I've been reading about name errors everywhere, and I can't see anything wrong with the code I'm using.

In xmulti_aeserver.py just above:
# main loop
while True:
.....
write nextcmd = ''. So it will be:
nextcmd = ''
# main loop
while True:
.....
This will define the nextcmd.
Add to this IF statment:
elif data != '':
# get next command
sys.stdout.write(data)
nextcmd = raw_input()
elif data == '':
nextcmd = raw_input()
else:
nextcmd = raw_input()

You only define nextcmd in one branch of an if-else statement:
elif data != '':
# get next command
sys.stdout.write(data)
nextcmd = raw_input()
but then assume that it is defined on line 207. You are missing the case where data is the empty string, which prevents nextcmd from being defined when you try to access it.

It looks like you have
if data == 'quitted':
....
elif data != '':
....
nextcmd = raw_input()
But if data=='', nextcmd is not set to anything, which causes the error when you try and use it.

About python's socket backup

I've programmed a python script to backup my files, something like Dropbox.
But there are some bugs. I have a class called SyncServer, and there are two functions called __init__ and TF1 seperately. TF1 stands for "Thread Function 1".
When I write thread.start_new_thread(TF1, (conn, 0)), the first parameter, I sent a socket object in. Unfortunately, python's IDLE replied with an error: NameError: global name 'TF1' is not defined

Assumes that TF1 is a global.
"NameError: global name 'TF1' is not defined"
States that TF1 is not a global.
It must be that the assumption is wrong.
TF1 is a method function in a class. Therefore, it needs to be qualified either by the class name or by an object instance. Usually, self.TF1 is appropriate.
Please find a Python tutorial where class definitions are covered.
