Why would TCP packets consistently fail to arrive at the server when the client happily sent them?

You are sending very small numbers of bytes, so you're possibly falling foul of the Nagle algorithm, which will hold back the data you wish to send until a sensible amount of data has been buffered and is ready to be transmitted.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
