[Kea-users] Where to put data for kea.

[Marek Greško]

Hello,

I attached the script. It is not very mature, but does its job.

It reads the file /etc/sysconfig/kea-conf/subnets/${name-of-subnet} and generates /etc/kea/kea-dhcp4-reservations-${name-of-subnet}.conf and /etc/kea/kea-dhcp6-reservations-${name-of-subnet}.conf.

The source file looks like:

windows fd0f:xxxx::1000 192.168.1.20 81:11:11:11:11:11 00:xx:...:11 - hostname1
linux fd0f:xxxx::1001 192.168.1.21 81:11:11:11:11:12 00:xx:...:10 - hostname2
linux fd0f:xxxx::1002 192.168.1.22 81:11:11:11:11:13 MAC - hostname3

... where the columns mean:

group - additional config parameter added from /etc/sysconfig/kea-conf/dhcp4/groups/${name-of-group}

ipv6 address

ipv4 address

MAC address

DUID (if set to keyword MAC, MAC part of the DUID is matched against MAC address)

IAID

Hostname

Description (not mandatory)
