[Kea-users] Dynamnic option generation (boot-file-name)

[Marcin Jurczuk]

Hi Guys,

I'm fighting for past few days with kea setup for migration from ISC-DHCP.
I can't make file option in DHCP packet set to dynamic value:
My device expects  next-server and filename value provided by dhcp and
filename config path must be autogenerated and based on device MAC
I was able to set up option 67 with this:
     {
        "library": "/usr/lib/kea/hooks/libdhcp_flex_option.so",
        "parameters": {
          "options": [
            {
              "add": "concat(hexstring(pkt4.mac,''), '.cfg')",
              "client-class": "STB",
              "code": 67
            }
          ]
        }
      }

This works as expected in terms option generation but device don't want
option 67 - it wants boot-file in DHCP (bootp) packet

That seems very populat stuff in DOCSIS/PON world where boot-file is either
MAC/Serial/other dynamic string so there must be easy way to set this up :)

However all my attempts to make it for filename field failed.
Any idea how to achieve this without writing own hook ?

Thanks in advance.
