This install of dhcpd expects config files to be in #{etc}.
|
|
All state files (leases and pids) are stored in #{var}/dhcpd.
|
|
|
|
Dhcpd needs to run as root since it listens on privileged ports.
|
|
|
|
There are two plists because a single dhcpd process may do either
|
|
DHCPv4 or DHCPv6 but not both. Use one or both as needed.
|
|
|
|
Note that you must create the appropriate config files before starting
|
|
the services or dhcpd will refuse to run.
|
|
DHCPv4: #{etc}/dhcpd.conf
|
|
DHCPv6: #{etc}/dhcpd6.conf
|
|
|
|
Sample config files may be found in #{etc}.
