 "subnet4": [
   {
  "subnet": "192.168.0.0/24",
  "reservations": [ ... ]
   } ],

As far as I know the only required parameter in a subnet is the
"subnet" range. Pools are not required and without a pool there is no
available address so only known hosts which have a reservation can
get an address. This is a theory, i.e. you have to try it, but on
the paper it does exactly what you want.

Re: [Kea-users] Bind service to loopback address

2017-04-19 Thread Jason Guy

Hi Tomek,

I have not tried UDP as I was under the impression this is only used when
the DHCP subnet was directly connected. Everything I am doing requires DHCP
RELAY. I will need to go back and see if there is a way to specify the
loopback to be a UDP socket. The other idea I had was specifying the
loopback address on every interface. Seems like a less than elegant
solution though.

Thanks,
Jason

Kea uses raw sockets by default to receive DHCPv4 traffic. Raw sockets
receive raw packets, i.e. everything that comes over wire (ethernet
header, ip, udp and everything that follows). This is different on
loopback as there's no notion of ethernet headers there. Kea has some
support for loopback traffic handling, but it's not used extensively, so
did not receive much testing.

Have you tried setting dhcp-socket-type to udp? If that doesn't help at
all, can you open a ticket for this?

[Kea-users] Bind service to loopback address

2017-04-19 Thread Jason Guy

Hi folks,

I would like to leverage my routing on the host setup, and bind the kea
service to the loopback address I have configured. This would ultimately
allow me to deploy multiple kea servers with an "anycast" reachability.

ip addr show lo
...
inet 10.50.5.11/32 brd 10.50.5.11 scope global lo:1
...

Kea.conf:
...
"interfaces-config": {
"interfaces": [
"lo/10.50.5.11",
"eth0",
"eth1"
]
},


I have tried specifying this in a few ways, and the DHCP relay packets
reach the server, but Kea does not appear to process them. I thought about
putting the loopback on the ethernet interfaces as secondary addresses, but
wanted to understand why I can see the relay packets arrive but not picked
up by Kea.

Thanks,
Jason

Hello Malcom:

As per my private replies to you, we have identified the issue.   As a matter 
of expediency, I have created a ticket for your issue:

   http://kea.isc.org/ticket/5247#ticket

and we are working into our Kea 1.2 release which is in beta now.  Code freeze 
for final is Monday.  We felt this issue warranted a fix forthwith.  You'll 
need to register:

http://kea.isc.org/register

to view the ticket.

To recap the issue:   The v4 server does not increment assigned-leases when 
expired leases are renewed (same client) or reused (different client).  Since 
we decrement assigned-leases each time we expire a lease (as we should), the 
assigned-leases stat becomes incorrect with the first reissue of an expired 
lease.

Based on that stats you provided, it looks like client leases expire pretty 
frequently in your environment as your reclaim-leases stat is quite large.

Additionally testing shows  a similar error in v6 assigned-nas assigned-pds 
stats.  This will be corrected under the same ticket.

Thomas,


I would love to use 1.2 :)

Timing is unfortunate though. We're currently integrating Kea 1.1.0, and we 
might not have the time to upgrade to 1.2 when it's available.
If this is the case I'll have to fix the issue on 1.1.0 before we ship. If you 
provide an official patch, it will be easier :)

[Kea-users] Dynamically changing DHCP options based on current environment using hooks

2017-04-19 Thread Munroe Sollog

I have a network that has two gateways that can act as a device’s default 
gateway.  Currently I am running kea on two different servers.  Each server is 
configured to hand out half of the network’s ip space (non-overlapping).  Each 
server has a different default gateway configured.  This has the effect of load 
balancing users across both gateways.  For added robustness I wrote a simple 
perl script that checks to ensure each path is up and routing, when one goes 
down for whatever reason, the script stops the appropriate DHCP server so users 
aren’t directed to a black hole.  Finally the same script will start the DHCP 
server again when the path becomes functional again.

This setup has been working well, but I would like to take advantage of the Kea 
hook framework, so I can reproduce this functionality using a single kea 
instance.  I am looking for pointers and thoughts regarding writing a hook for 
this.  It looks like, at the moment,  I am locked into C++.  I’m not sure which 
hook to use to massage the default gw for every lease.
