I want my P2P application to works well even when users are behind
proxy or LAN.
i.e Two instance of my application should be able to communicate even
if they are on different LANs but indirrectly connected to internet.
To elaborate it further, suppose there is a computer on my office LAN
running my application. This computer is connected to internet through
our Proxy server. Now any other computer which is also on LAN and is
indirectly connected to internet should be able to exchange files. We
want to achieve this without installing anything on Proxy server.
I have seen software KAZAA, which allows different users to exchange
files even behind proxies,firewal ls. We just need to open a Port on
Proxy Server.
How can i achieve this functionality in C#?
Waiting for your valuable reply,

You might want to consider making your P2P application go on HTTP ports
(80). Or better still, make them web services.. That should give you
most open implementation with the ability to allow web-admins to block
some of this traffic if not desired.

Are you sure in KAZAA, each client doesn't go thru an outside server
to talk to each other?
If it is, it is easy to implement else you need a sniffer to
found out how Kazaa did it.
MS's NetMonitor or OpenSource Ethereal will help you do that.

Hello-
I have a python routine (Python 2.2.3 on Windows 2000 "Professional") using
a socket connection. Problem is, the backend service I'm connecting to will
hang every so often and the socket will simply wait for a response which
will never come. I'm thinking of putting in a routine to check the socket's
status, which now brings in threading. Before I go to the trouble I thought
I'd ask if there is a simple way to verify my socket...

I'm not a new programmer, but this one's got me stymied; hopefully it's a fairly trivial problem.
I'm using a socket connection to receive communication from a server. Normally, the entire message is received before the program moves on with its next instructions.

Hi,
I'm going to develop a socket communication between an instrument (running
CE 5.0 with Compact Fraework V2) and a PC. As the instrument should only
connect to one PC at a time I believe that the sync version of the socket
should be the easiest - or what??? (please tell if I'm wrong).
Are there anyone who is able to point to a Server and Client example code in
C# VS2005 (I've only been able to find a C++ version) ???

I was wondering if someone could give me some general pointers about creating client server applications that would be able to communicate with each other over not just the LAN which I am able to do, but would be able to communicate with each other and exchange filestreams over the internet, meaning in most cases communication with PC's behind a router and / or a gateway server. I have applications that can send messages to each other and...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
