Is it OK to close listenSocket after accept?

[Ole]

When creating a socket connection a typical scenario is:
MySocket = ListenSocket.Accept();

but if only one connection is necessary will it then not be better to close
the ListenSocket after that line?

Thanks
Ole

Hello, Ole!

Well, you can close listening socket after receiving one connection.
Nothing bad will happen.

Another option is not calling Socket.Accept(...);

The latter is more flexible, because if you loose that one connection
you can accept another one. And you will not have to do all the bindings again
( Socket.Bind() , Socket.Listen(... ) )

Also the latter option is more secure. Imagine the situation when you've received a connection,
and closed listening socket. In the mean time another application ( malware etc ) binds on the
same address and: a) intercept your clients b)introduce denial-of-service attack

What should I do instead of calling Socket.Accept to make a connection?

Thanks

Hello, Ole!

To make a connection ( to connect ) on some host you can use
Socket.Connect(...) method.
To accept connection from another host you use Socket.Accept(...).

Its by design
