ISC DHCP Howto (1)

This howto is based on the following documentation:

• Home Router [EN] @ Gentoo Wiki

Installation

Synchronize the repository and show dependencies:

emaint --auto sync
emerge --update --pretend 'net-misc/dhcp'

Install the package:

emerge --update 'net-misc/dhcp'

Configuration

Edit the following files:

• /etc/conf.d/dhcpd
• /etc/dhcp/dhcpd.conf
• /root/etc/raysoft.loc.json

Validate the JSON file:

python -m 'json.tools' '/root/etc/raysoft.loc.json'

Run the script mk-named-dhcpd-conf.py to generate the file dhcpd-hosts.conf:

/root/bin/mk-named-dhcpd-conf.py '/root/etc/raysoft.loc.json'

Move the file:

install --mode=0644 --owner='root' --group='root' --target-directory='/etc/dhcp' \
  'dhcpd-hosts.conf'

Validate the configuration:

dhcpd -t -cf '/etc/dhcp/dhcpd.conf'

Start the daemon:

/etc/init.d/dhcpd start

Include the daemon to the start procedure:

rc-update add 'dhcpd' 'default'
rc-update show | grep 'dhcpd'

Output:

                dhcpd |      default

Test

Test the listener's availability

netstat --numeric --program --listening --all --tcp --udp | grep ':67 '

Output:

udp        0      0 0.0.0.0:67              0.0.0.0:*               2786/dhcpd
