Sockets close
 

Hi, Im kind of new to this and I have a problem...
Im using asynchronous non-blocking sockets on my Gnutella, and just after I make a successfull connection, I send a ping, receive pongs, and then the socket disconnects. Im using plain send() and recv() calls and a main poll cycle which constantly checks for incoming packets. Im not sure if the problem is that Im getting out of sync or that I should send pings more often to keep the connection alive. Im also getting lots of query, pongs, pings, etc which I (guess) successfully broadcast. Just after that, the socket resets the connection.

eg. a poll tells me I have incoming data to handle, and then my receive function receives 0 bytes. Why's that?

Thanks

please someone!!! im almost on deadline for this project...

What client are you connecting to and what protocol version are you using?

Re: Sockets close
 

those two things does not mach to each other.

thanks, maybe Im a bit confused about how are asynchronous sockets implemented. I've read everything I've found about gnutella, and I really cant figure out how this is actually done. So I decided to do it my way...dunno if what Im doing has a name.
Sorry about reinventing the wheel, I really have to.
So is what Im doing fully wrong, Im headin the wrong way?

tshdos:
Im using 0.4 handshaking, and Im connecting to a localhost with mutella, which parses me a bunch of pongs (from internet) to which I connect (so I dont know what clients Im connecting to)..

Im really afraid bout having to start my gnutella over again and make things right this time..
so, please could somebody give me a clear explanation of how asynchronous sockets work? pleezzzzzz

You really should use 0.6 handshaking. Its not much more difficult and everyone else is using it.

I don't have a good answear to your question. I suppose you do aswear any pings you receive?

Here you can find s.th. about network programming. Maybe this will help you.
