# -*- Perl -*-
# test the Net::Ident module, which is a bitch, because you really
# need an ident daemon to test it, and then you usually get a connection
# from a remote machine, and then ask for the username.
# so what we do is try to make a connection to an ident daemon, on
# some machine, and if that succeeds, see if we can do a successful lookup
# on that.
# This isn't guaranteed to succeed. If you are not (properly) connected
# to the internet, and if your localhost doesn't run an ident daemon,
# then this script won't work. If you do know a machine that you can
# currently reach, which runs an ident daemon, then put it's name or
# IPnumber in the 'hosts' file in the t/ directory.
