I'm writing a Telnet Server application using
Asynchronous sockets.
I spawn a listener thread to handel incomming connections
and create a separate client socket for each new
connection.
I then set the new client socket to BeginReceive().
My problem: When two client socket connections send data

I have a question about C#. How can I stop asynchronous read/write operation
( BeginReceive() / BeginSend() ) if timeout occurs?
The Socket class doesn't make any cancel method available.
I used CancelIo(HANDLE hFile) method (declared in Winbase.h) in C++.
Thanks for help.

Hi all,
I've got a server that handles a relatively high number of concurrent
transactions (on the magnitude of 1000's per second). Client
applications establish socket connections with the server. Data is
sent and received over these connections using the asynchronous model.
The server is currently in beta testing. Sporadically over the course
of the day, I'll observe the thread count on the process (via perfmon)
start climbing....

I'm writing a little console socket server but I'm having some
difficulty. Can I ask your advice - where is the best place to get
some help on that topic? It would be nice if some people who knew what
they were doing could take a look at my code and tell me where and why
I'm going wrong.
Any suggestions of groups or forums?

Hi,
I'm having a problem with asynchronous HttpWebRequest. It's a simple
http client-server. For most of my users it works fine. However, some
of them get the exception:
System.Net.WebException: Unable to connect to the remote server --->
System.Net.Sockets.SocketException: The attempted operation is not
supported for the type of object referenced
at System.Net.Sockets.Socket.get_ConnectEx()

I am trying to create a socket server which will listen for connections from
multiple clients and call subroutines in a Fortran DLL and pass the results
back to the client. The asynchronous socket client and asynchronous socket
server example code provided in the .NET framework developers guide is a
great start but I have not dealt with sockets before and I am struggling with
something.
From what I can tell the sample server code ...

Hi everytbody,
I'm experiencing some problems trying to asynchronously read data from a
Socket object. What I do now is:
1) call th BeginReceive(...) method on the Socket object;
2) within the asynchronous callback method, call the EndReceive method,
getting the number of read bytes (stored in a variable called rb)
3) if (rb>0) I can suppose there are still some other bytes to be read,
so call again the BeginReceive(...) method, else...

Hello everyone here.
This is my first post in this newsgroup, I hope I won't be to much
off-topic. Feel free to redirect me to any better group.
I am getting strange timing issues when failing to asynchronously connect
sockets on closed or filtered ports, but I'm quite unsure if this is a PHP
issue or my misunderstanding, as it seems that socket streams only wrap
around <sys/socket.h>.

Hi,
I'm trying to implement an asynchronous scheduler for asyncore to call
functions at a later time without blocking the main loop.
The logic behind it consists in:
- adding the scheduled functions into a heapified list
- calling a "scheduler" function at every loop which checks the
scheduled functions due to expire soonest
Note that, by using a heap, the first element of the list is always

I am currently learning how to create and manage the different types of VPNs and I have a question about LAN-to-LAN VPNs.

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...
