socket connect loop - pytohn

hello experts,
i created a simple chat server using socket in python.

my problem is that i want the client to try connect to the server until the connection is made..(when i set the timeout of the socket)

however, when the connection fail(timeout), i did another request but it done immediately.
here is the code:
from socket import *
s = socket(AF_INET, SOCK_STREAM)
s.settimeout(10)
connected = False
    while connected != True:
        try:
            s.connect(('localhost', 12345))
            connected = True
        except error:
            print "could not connected to server now.. Tries to connect again.."

#rest of the code...

Open in new window


is there any way to reset the timeout or i have to close that socket and open new one..

by the way, only when i set the timeout of the socket it doesn't work, if i don't set the timeout of the socket, it works..

thanks ahead..

don't do it yourself, use select http://docs.python.org/library/select.html

recvSockHost = '224.110.0.1'
recvSockPort = 10001

recvSock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM, socket.IPPROTO_UDP)
recvSock.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
recvSockId = recvSock.fileno()



inputReady, _, _ = select.select([recvSock], [], [], .01)
                  
    for activeSocket in inputReady:
        if activeSocket == recvSock:
           DoStuff()

Open in new window

Understandable, but when the wheel has been invented several times (with much better results)  why do you want to make a square wheel?
Your help has saved me hundreds of hours of internet surfing.
