-OpenVPN plugin examples.
-
-Examples provided:
-
-simple.c -- using the --auth-user-pass-verify callback, verify
- that the username/password is "foo"/"bar".
-
-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)
