+# Keyboard socket server
+
+The server has two jobs, to authenticate and to accept a stream of key presses from the client.
+
+For efficiency and security we support use of a unix socket, but tcp can be used instead
+
+# Picking a socket type and setting the listener
+
+
+``` go
+--- create listener
+
+@{unixSocketPath} // gets unixSocketPath from environment, unixSocketPathExists defines if it exists
+@{TCPBindAddress} // gets tcpBindAddress from environment, tcpBindAddressExists defines if it exists
+@{TCPBindPort} // gets tcpBindPort from environment, tcpBindPortExists defines if it exists
+
+
+if unixSocketPathExists {
+    listener, _ = net.Listen("unix", unixSocketPath)
+} else{
+    if tcpBindAddressExists && tcpBindPortExists {
+        listener, _ = net.Listen("tcp", tcpBindAddress + ":" + tcpBindPort)
+    } else {
