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>. =head1 SEE ALSO L, L =head1 AUTHORS Graham Barr, the original Configure script of libnet.
