-OpenVPN plugin examples.
-
-Examples provided:
-
-simple.c -- using the --auth-user-pass-verify callback,
-            test deferred authentication.
-
-To build:
-
-  ./build simple (Linux/BSD/etc.)
-  ./winbuild simple (MinGW on Windows)
-
-To use in OpenVPN, add to config file:
-
-  plugin simple.so (Linux/BSD/etc.)
-  plugin simple.dll (MinGW on Windows)

- * This file implements a simple OpenVPN plugin module which

- * 
- * Will run on Windows or *nix.
- *
- * Sample usage:
- *
- * setenv test_deferred_auth 20
- * setenv test_packet_filter 10
- * plugin plugin/defer/simple.so
- *
- * This will enable deferred authentication to occur 20

- * and will cause a packet filter file to be generated 10
- * seconds after the initial TLS negotiation, using
- * {common-name}.pf as the source.
- *
- * Sample packet filter configuration:
- *
- * [CLIENTS DROP]
- * +otherclient
- * [SUBNETS DROP]
- * +10.0.0.0/8
- * -10.10.0.8
- * [END]
