=head1 NAME

libnetcfg - configure libnet

=head1 DESCRIPTION

The libnetcfg utility can be used to configure the libnet.
Starting from perl 5.8 libnet is part of the standard Perl
distribution, but the libnetcfg can be used for any libnet
installation.

=head1 USAGE

Without arguments libnetcfg displays the current configuration.

$ libnetcfg
    # old config ./libnet.cfg
    daytime_hosts        ntp1.none.such
    ftp_int_passive      0
    ftp_testhost         ftp.funet.fi
    inet_domain          none.such
    nntp_hosts           nntp.none.such
    ph_hosts             
    pop3_hosts           pop.none.such
    smtp_hosts           smtp.none.such
    snpp_hosts           
    test_exist           1
    test_hosts           1
    time_hosts           ntp.none.such
    # libnetcfg -h for help
    $

It tells where the old configuration file was found (if found).

The C<-h> option will show a usage message.

To change the configuration you will need to use either the C<-c> or
the C<-d> options.

The default name of the old configuration file is by default
"libnet.cfg", unless otherwise specified using the -i option,
C<-i oldfile>, and it is searched first from the current directory,
and then from your module path.

The default name of the new configuration file is "libnet.cfg", and by
default it is written to the current directory, unless otherwise
specified using the -o option, C<-o newfile>.

By default Net::FTP assumes that it only needs to use a firewall if it
cannot resolve the name of the host given. This only works if your DNS
system is setup to only resolve internal hostnames. If this is not the
case and your DNS will resolve external hostnames, then another method
is needed. Net::Config can do this if you provide the netmasks that
describe your internal network. Each netmask should be entered in the
form x.x.x.x/y, for example 127.0.0.0/8 or 214.8.16.32/24

Normally when FTP needs a data connection the client tells the server
a port to connect to, and the server initiates a connection to the client.

Some setups, in particular firewall setups, can/do not work using this

server, this is called a passive transfer.
