[erlang-questions] Peername of a closed TCP socket

[Tony Rogvall]

You can try the inet option:
	{exit_on_close, false}
This will keep the port and the socket active so you can read  
statistics,
continue write data to a half open socket and possibly get the  
peername, if that is available
by the underlying operating system.

You must then call gen_tcp:close to terminate the port/socket
