Hello,
I have a short program that the client make a connection to server, a thread is then created to poll any data sent from the server. The main thread will close the socket after 5 seconds. Here are the code:
from socket import *
import select
import threading
import time
def poll(c):

Hi,
I am having some problem with callback used in socket implementation.
private static void Connect(string strPrtrIPAddr, int intPrtrPort, ref
Socket rsocClient)
{
try

// Create remote end point.
System.Net.IPAddress IPAddress = System.Net.IPAddress.Parse(strPrtrIPAddr);
System.Net.IPEndPoint IPEndPoint = new System.Net.IPEndPoint(IPAddress,

I am not sure if this is a bug or not but it seems strange to me. If I set
the tcp socket blocking to false and do a connect, then I can catch the
socketexception. If the exception is WSAEWOULDBLOCK, then I do a poll with
timeout to see if I can connect to the remote host. When the poll returns
true, the socket Connected property is still false. Why is this?
sock.Blocking = false;
try
{
sock.connect (...)

The following code behaves differently from what I would expect:
socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream,
System.Net.Sockets.ProtocolType.Tcp);
socket.Blocking = false;
socket.Connect(ipe);
isConnected = socket.Poll(30*1000000, SelectMode.SelectWrite);
I would have expected that once I set the socket to non-blocking, the
connect would return immediately and the poll would wait up to 30 seconds

Hello Fellow Developer,
I use the System.Net.Sockets to send/receive data (no
tcpclient/tcplistener), I made a receivethread in my wrapper, the
receivethread loops/sleeps while waiting for data and then fires a
datareceived event.
Within the waitingloop there is a timeout function, but I want the the
'last-time-socket-used' variable set when the socket is finished sending.
When I send by System.Net.Sockets.Socket.Send(buffer()) (<--this...

Hi,
I try to implement a reusable socket class to send and receive data.
It seems to work but I have 2 problems :
1) I rely on Socket.Available to detect that the connection is closed (no
more data to expect). Sometimes, Socket.Available returns 0 but the other
end of the connection did not close it !
2) This class will be used by many other classes so I have to use the

We have an application that has a 200 count loop that does the following:
' Each time thru the loop we pass the next IP Address is a range (aka
192.168.4.50 thru 192.168.4.254)

If mUIO_Threads(i) Is Nothing Then

Hi,
In an attempt to create a full-blown webcrawler I've found myself
writing a wrapper around the Socket class in an attempt to make it
completely async, supporting timeouts and some scheduling mechanisms.
I use a non-blocking approach for this, using the call to 'poll' to
support the async mechanism - rather than the 'begin' and 'end'
functions. I already found that connecting doesn't set the
"isconnected" variable correctly...

I'm a network technician in training and I need your help.
I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.
The last exercise I practiced was to create a LAN-to-LAN VPN between two Pfsense firewalls, by using IPSEC protocols.
I succeeded, with both firewalls in the same network. But I'm wondering if it's possible to do the same thing, with 2 Pfsense firewalls...
