Я написал клиент-серверную программу на Python, где клиент может отправлять данные на сервер. Но когда клиент пытается соединиться с сервером, я получаю следующую ошибку.
[Errno 110] Connection timed out
Sending Key to Server
Traceback (most recent call last):
File "client.py", line 43, in <module>
s.send(str(id))
socket.error: [Errno 32] Broken pipe
Я попробовал следующие решения
Ошибка сломанной трубы и Как предотвратить ошибку сломанной трубы , но ни одна из них не решила проблему.
Вот мой код клиента и сервера
client.py
import socket
import os
import subprocess
from optparse import OptionParser
from random import randint
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "Socket has been successfully created"
except socket.error as err:
print "socket creation failed with error %s" %(err)
# The Manager Address and port
host_ip='192.168.43.123'
port =10106
# Generates a random number say xxxx then its client id becomes 'clxxxx' and home directory made at the server as '/home/clxxxx' with permissions 700
def random_with_N_digits(n):
range_start = 10**(n-1)
range_end = (10**n)-1
return randint(range_start, range_end)
id=random_with_N_digits(4)
id="cl"+ str(id)
# Looks for a public key in .ssh folder if temp.pub not present. If not found generates a ssh public private key and sends it to manager which then copies it to the server
subprocess.call(["bash","keygen.sh"])
#s = socket.socket()
try:
s.connect((host_ip,port))
print "the socket has successfully connected to Backup Server IP == %s" %(host_ip)
except socket.error as err:
print err
f = open('temp.pub','r')
print "Sending Key to Server"
j = "-"
s.send(str(id))
l=f.read(8192)
while(l):
print 'Sending...'
s.send(l)
l = f.read(8192)
try:
client_id=s.recv(1024)
data=s.recv(12)
ip=s.recv(24)
print client_id,
print data, ip
except:
print "An Unknown Error Occurred!"
f.close()
# Writes the parameters of client in the file 'backup_dir.txt'
with open('backup_dir.txt','w') as the_file:
the_file.write(client_id)
the_file.write('\n')
the_file.write(data)
the_file.write('\n')
the_file.write(ip)
the_file.write('\n')
f.close()
s.close()
server.py
import socket
import subprocess
import os
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
print "Socket has been successfully created"
except socket.error as err:
print "socket creation failed with error %s" %(err)
port = 10106
s.bind(('', port))
print("socket binded to %s port" %port)
s.listen(10)
print("socket is listening")
while(True):
print("waiting for a connection")
c, addr = s.accept()
print("Got a connection from", addr,c)
clientID =(c.recv(8192))
key =(c.recv(8192))
print clientID
print key
with open("temp.pub", 'w') as fp:
fp.write(key)
note=subprocess.check_output("./test_user.sh "+ clientID, shell=True)
note = str(note)
print(len(note))
flag, path, serverIP = note.split(":")
print(flag)
print(path)
print(serverIP)
if flag:
c.send(clientID)
c.send(path)
c.send(serverIP)
os.remove("temp.pub")
else:
c.send("Unable to add Client.")
Как мне исправить эту проблему, чтобы клиент мог отправлять данные на сервер без каких-либо ошибок?
Заранее спасибо.
