SSL over TCP Client\server

[Tal Bar-Or]

Hi All ,

I need to write some basic tcp client/server that communicate over SSL
Its seems i managed to run the server side listen with SSL but i am missing the 
client part.
If someone could advice me how to saet the client will be appreciated
Thanks


Server side


class SingleTCPHandler(socketserver.BaseRequestHandler):
"One instance per connection.  Override handle(self) to customize action."


def handle(self):
try:


#print(self.server.serverset)
data = json.loads(self.request.recv(1024).decode('UTF-8').strip())
# process the data, i.e. print it:
#print(self.client_address)

print(data['AuthPass'],self.server.serverset['CryptKey'],self.server.serverset['Password'])
Authstart = 
AuthMec(data['AuthPass'],self.server.serverset['CryptKey'],self.server.serverset['Password'])
Authstart.DecPass()


# send some 'ok' back
#self.server.serverset['QuarantineIp']

self.request.sendall(bytes(json.dumps({'QuarantineIp':self.server.serverset['QuarantineIp'],'SERVERIP':self.client_address[0]}),
 'UTF-8'))
except Exception as e:
print("Exception wile receiving message: ", e)


class TcpSessionServer(socketserver.ThreadingMixIn, socketserver.TCPServer):
# Ctrl-C will cleanly kill all spawned threads
daemon_threads = True
# much faster rebinding
allow_reuse_address = True
test = "test"

def __init__(self, server_address, RequestHandlerClass):
socketserver.TCPServer.__init__(self, server_address, 
RequestHandlerClass)
self.socket = ssl.wrap_socket(
self.socket, server_side=True, 
certfile="cert.pem",do_handshake_on_connect=False)
#read configuraiton and seve it as class member
serverinit = GetServerInfo()


Clent Side
===

class TcpClientConnect:
def __init__(self,Datapayload,EnforcementHost,SrvPort):
self.Datapayload = Datapayload
self.EnforcementHost = EnforcementHost
self.SrvPort = SrvPort

def ContactEnforcementHost(self):
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((self.EnforcementHost, int(self.SrvPort)))
s.send(bytes(json.dumps(self.Datapayload), 'UTF-8'))
#Waiting for results
result = s.recv(1024)
txres =  result.decode('UTF-8')
print(txres)

jsresult = json.loads(txres)
print("%s"%jsresult)
s.close()

Hello All,

Please advice 
Thanks

import os,time

sharkCall = ["tshark","-i" ,"1", "-w",os.getcwd() +'/smbsession.pcap']
sharkProc = subprocess.Popen(sharkCall,executable="C:/Program 
Files/Wireshark/tshark.exe")
localip = socket.gethostbyname(socket.gethostname())

a = 0

while a ==0:
a = sharkProc.pid
time.sleep(2)


ipflt = ''

listip = socket.gethostbyname_ex('media.isilon.gefen.local')[2]

for ip in listip:
ipflt= ipflt+ "ip.addr==" + ip + "||"
ipflt = ipflt + "ip.addr==" + localip

if ipflt.endswith('||'):
ipflt = ipflt[:-2]
print (ipflt)
b= os.path.getsize("//media.isilon.gofn.local/Media/New Text Document.txt")
#statinfo
print(b)


#time.sleep(2)
sharkProc.kill()
tsharkCall = 
["tshark","-r",'C:/traces_test/smbsession.pcap',"-Y",ipflt,"-T","fields","-e","ip.src","-e","ip.dst","-e","smb.file",\
