✨ LIBNETCFG ✨

okay bestie, welcome to libnetcfg — the lil utility that lives in the Perl Programmers Reference Guide, and yes it's the glow-up era of the classic libnetcfg page 💅

🎀 NAME 🎀

libnetcfg — configure libnet, fr fr

🌸 DESCRIPTION 🌸

So like, the libnetcfg utility is literally the tool you use to configure libnet. Starting from perl 5.8, libnet is part of the standard Perl distribution — iconic — but libnetcfg can be used for any libnet installation. Any. Of them. No cap. 🦋

💖 USAGE 💖

no arguments? it just spills the tea ☕

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 you where the old configuration file was found — if it was found. (if not… well, nothing to report, bestie 🫶)

The -h option will show a usage message. handy!

actually changing stuff 🔥

To change the configuration you will need to use either the -c or the -d options. those two, pick one.

the old config file situation 📁

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. like it checks your room first and then the rest of the house. 💀

the new config file situation ✨

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. so if you don't say otherwise it's dropping it right where you're standing. main character energy honestly 👑

bestie heads up: nothing here gets written unless you bring -c, -d, -i, or -o to the party. no arguments = read only, look don't touch vibes. 🙈
