| 38 | =head1 NAME |
| 39 | |
| 40 | libnetcfg - configure libnet |
| 41 | |
| 42 | =head1 DESCRIPTION |
| 43 | |
| 44 | The libnetcfg utility can be used to configure the libnet. |
| 45 | Starting from perl 5.8 libnet is part of the standard Perl |
| 46 | distribution, but the libnetcfg can be used for any libnet |
| 47 | installation. |
| 48 | |
| 49 | =head1 USAGE |
| 50 | |
| 51 | Without arguments libnetcfg displays the current configuration. |
| 52 | |
| 53 | $ libnetcfg |
| 54 | # old config ./libnet.cfg |
| 55 | daytime_hosts ntp1.none.such |
| 56 | ftp_int_passive 0 |
| 57 | ftp_testhost ftp.funet.fi |
| 58 | inet_domain none.such |
| 59 | nntp_hosts nntp.none.such |
| 60 | ph_hosts |
| 61 | pop3_hosts pop.none.such |
| 62 | smtp_hosts smtp.none.such |
| 63 | snpp_hosts |
| 64 | test_exist 1 |
| 65 | test_hosts 1 |
| 66 | time_hosts ntp.none.such |
| 67 | # libnetcfg -h for help |
| 68 | $ |
| 69 | |
| 70 | It tells where the old configuration file was found (if found). |
| 71 | |
| 72 | The C<-h> option will show a usage message. |
| 73 | |
| 74 | To change the configuration you will need to use either the C<-c> or |
| 75 | the C<-d> options. |
| 76 | |
| 77 | The default name of the old configuration file is by default |
| 78 | "libnet.cfg", unless otherwise specified using the -i option, |
| 79 | C<-i oldfile>, and it is searched first from the current directory, |
| 80 | and then from your module path. |
| 81 | |
| 82 | The default name of the new configuration file is "libnet.cfg", and by |
| 83 | default it is written to the current directory, unless otherwise |
| 84 | specified using the -o option, C<-o newfile>. |
