Hi! And what about the FBSD's inetd's builtin identd (auth) and the -g option? man inetd: Currently, the only internal service to take arguments is ``auth''. Without options, the service will always return ``ERROR : HIDDEN-USER''. The available arguments to this service that alter its behavior are: -g Instead of returning the user's name to the ident requester, report a username made up of random alphanumeric characters, e.g. ``c0c993''. The -g flag overrides not only the user names, but also any fallback name, .fakeid or .noident files.
