LIBNETCFG(1)

okay so welcome to the LIBNETCFG(1) page, bestie 💖 — we're talking about libnetcfg, the utility that configures libnet. no cap, it's giving practical and iconic ✨

✨ NAME ✨

libnetcfg — configure libnet 💅

🌸 DESCRIPTION 🌸

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

🎀 USAGE 🎀

Without arguments, libnetcfg displays the current configuration. like, zero arguments, zero stress 🫶

$ 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 you where the old configuration file was found — if it was found, periodt. 🍓

The -h option will show a usage message. helpful queen behavior ✨

To change the configuration you will need to use either the -c or the -d options. iykyk 💅

okay so the options in question, bestie:

• -h — will show a usage message. short and sweet
• -c — one of the two options you'll need to use to change the configuration (the other is -d). 🌈
• -d — the other option you'll need to use to change the configuration (alongside -c). 💀
• -i oldfile — the option for specifying a different old configuration file; the literal invocation is -i oldfile. 🍓
• -o newfile — the option for specifying a different new configuration file; the literal invocation is -o newfile. 🎀

The default name of the old configuration file is, by default, libnet.cfg, unless otherwise specified using the -i option, -i oldfile, and it is searched first from the current directory, and then from your module path. first current dir, then module path — got it? 🦋

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, -o newfile. default new file goes in the current directory, periodt 💅
