port doubling (or...)?

[maximilianscherr]

hmm would this work?
i made a bit witht he socketserver module, but dunno if that will 
work or if it's useless performance loss.
it works like this:
the client connects to the pserver, then it sends data to uoserver.
if the uoserver connects the pserver sends the data to the client.
note: the pserver is on the machine which runs the client to keep 
performance on the uoserver pc low.
or how would i do that or what would be the advantages or 
disadvantages?

sorry for the long posts and annoying questions.

thanks in advance

this give sme errors:( i the ipaddrmatch line:
def getipaddr():
    smtpconn = smtplib.SMTP("mail.mojam.com")
    smtpconnhelo = smtpconn.helo()
    smtpconn.quit()
    ipaddrmatch = re.search("([0-9] + \.[0-9] + \.[0-9] + \.[0-9] 
+ )", smtpconnhelo)
    if ipadrrmatch is not None:
        return ipaddrmatch.group(1)

the server code:
def startps():
    class psrequesthandler(SocketServer.StreamRequestHandler):
        def handle(self):
            reqaddr = self.client_address()
            reqipaddr = socket.gethostbyname(reqaddr[1])
            cliaddr = ()
            if reqipaddr == getipaddr():
                try:
                    cliaddr = reqaddr
                    uoanas3 = socket.socket(socket.AF_INET, 
socket.SOCK_STREAM)
                    uoanas3.connect(("uoana.dyndns.org", 5003))
                    smsgstr3 = self.rfile()
                    while len(smsgstr3):
                        smsgstr3 = smsgstr3[smsgstr3.send(smsgstr3):]

                    uoanas3.close()

                except:
                    tkMessageBox.showerror("Error", "Couldn't connect 
to server!")                    

            if reqipaddr == socket.gethostbyname("uoana.dyndns.org"):
                try:
                    uoanas4 = socket.socket(socket.AF_INET, 
socket.SOCK_STREAM)
                    uoanas4.connect(cliaddr)
                    smsgstr4 = self.rfile()
                    while len(smsgstr4):
                        smsgstr4 = smsgstr4[smsgstr4.send(smsgstr4):]

                    uoana4.close()

                except:
                    tkMessageBox.showerror("Error", "Couldn't connect 
to server!")                    

    ps = SocketServer.ThreadingTCPServer((getipaddr(), 5002), 
psrequesthandler)
    ps.serve_forever()

please tell me what i do wrong or not, couldn't test the server code 
due to erors in the getip def.
