Programming Forums - View Single Post - How do I reconnect a disconnected socket?

I'm trying to make something that once it is disconnected will automatically try to reconnect. I'll add some more features in later so it doesn't hammer the server but right now I just want to keep it simple and get that part working. The problem is that when I use sock.close I get an error message of

(Toggle Plain Text)

Bad File Descriptor

and if I either use shutdown or just go straight to reconnecting I get:

(Toggle Plain Text)

Transport endpoint is already connected

This is what I've got right now:

 python Syntax (Toggle Plain Text) 
#! /usr/bin/env python
import socket, string
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
def doconn():
    sock.connect(("localhost", 1234))
def dodiscon():
    sock.close()
    doconn()
 
doconn()
 
while (1):
    buffer = sock.recv(1024)
    if not buffer:
        dodiscon()
#! /usr/bin/env python
import socket, string
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
def doconn():
    sock.connect(("localhost", 1234))
def dodiscon():
    sock.close()
    doconn()

doconn()

while (1):
    buffer = sock.recv(1024)
    if not buffer:
        dodiscon()

What am I doing wrong?
