[erlang-questions] How to write a TCP server in Erlang?

[Matej Kosik]

Hello,

Can somebody recommend me some great tutorials on TCP servers (and clients) written in Erlang? The reference manual is quite clear, however according to that information I am failing to implement what I need (I am ashamed).

The attached code works. A single packet is successfully transmitted from the client to the server. However, if I try to send another packet, the `recv' operation at server side instead of returning

	{ok, SomeBinaryData}

Returns

	{error,closed}

That is, the socket gets closed immediatelly after the first receive.

How to do these two transmissions correctly? For example, how to write a simple TCP server that for each connected client acts as an echo server (i.e. it sends back what it received)?

Thank you very much for any kind of helpful pointers.

Regards
