Hello,
I have a program that opens up a connection to port 10000 of a server and sends it some data. It works normally. I'm trying to "stunnel" both ends.
In my program I create a socket, connect to local port 7033, send my data, and close the socket. I verified that every function call returns success (socket, setsockopt (for TCP_NODELAY), gethostbyname, connect, and send).
From what the logs show below, it seems that server stunnel gets the
connection from the client stunnel, they successfully negotiate the SSL stuff, then the client stunnel waits for any data to proxy to the server stunnel. The server stunnel is waiting too, and after 10 seconds of no data, it closes the socket.
For some reason the client stunnel is not getting my data and therefore doesn't forward anything over to the server stunnel. I'm not sure why this is happening, because my program works normally and I've verified that everything returned success.
Any ideas?
