- Frequently Asked Questions
-
- This chapter contains a number of frequently asked questions and
- troubleshooting tips. It currently lacks content, but it is expected to grow
- over time.

- General Frequently Asked Questions
-
-
- Where did the Kea name came from?
-
- Kea is the name of a high mountain parrot living in New Zealand.
- See this https://lists.isc.org/pipermail/kea-users/2014-October/000032.html
- for an extended answer.
-
-
-
-
- Feature X is not supported yet. When/if will it be available?
-
- Kea is developed by a small team of engineers. Our resources are
- limited, so we need to prioritize requests. The complexity of a new
- feature (how difficult it is to implement a feature and how likely it
- would break something that already works), amount of work required and
- expected popularity (i.e., how many users would actually benefit from it)
- are three leading factors. We sometimes also have contractual obligations.
-
-
- Simply stating that you'd like feature X is useful. We try to
- implement features that are actively requested first, but the reality
- is that we have more requests than we can handle, so some of them must
- be postponed, at least in the near future. So is your request likely to
- be rejected? Not at all. You can do many things to greatly improve the
- chances of your request being fulfilled. First, it helps to explain why you
- need a feature. If your explanation is reasonable and there are likely
- other users that would benefit from it, the chances for Kea developers
- to put this task on a roadmap is better. Saying that you are willing
- to participate in tests (e.g., test engineering drops when they become
- available) is also helpful.
-
- Another thing you can do to greatly improve the chances of a feature
- to appear is to actually develop it on your own and submit a patch.
- That's an avenue that people often forget about. Kea is open source
- software and we do accept patches. There are certain requirements, like
- code quality, comments, unit-tests, documentation, etc., but we have
- accepted a significant number of patches in the past, so it's doable.
- Accepted contributions range from minor documentation corrections to
- significant new features, like support for a new database type. Before
- considering writing and submitting a patch, make sure you read
- the Contributor's Guide in the
- Kea Developer's Guide.
-
-
- Kea is developed by ISC, which is a non-profit organization.
- You may consider signing a development contract with us. In the past
- we did implement certain features due to contractual obligations.
- With additional funds we are able to put extra engineering efforts
- into Kea development. We can reshuffle our schedule or add extra
- hands to the team if needed. Please keep in mind that Kea is
- open source software and its principle goal is to provide a good DHCP
- solution that can be used by everyone. In other words, we may
- refuse a contract that would tie the solution to specific proprietary
- technology or make it unusable for other users. Also, we strive to
- make Kea a reference implementation, so if your proposal significantly
- violates a RFC, we may have a problem with that. Nevertheless, please
- talk to us and we may be able to find a solution.
-
- Finally, Kea has a public
- roadmap, with releases happening several times each year. We tend
- to not modify plans for the current milestone, unless there are very good
- reasons to do so. Therefore "I'd like a feature X in 6 months" is much
- better received than "I'd like a feature X now".

- Frequently Asked Questions about DHCPv4
-
-
- I set up a firewall, but the Kea server still receives the traffic. Why?
-
- Any DHCPv4 server must be able to receive from and send traffic to
- hosts that don't have an IPv4 address assigned yet. That is typically not
- possible with regular UDP sockets, therefore the Kea DHCPv4 server uses raw
- sockets by default. Raw sockets mean that the incoming packets are received
- as raw Ethernet frames, thus bypassing the whole kernel IP stack, including
- any firewalling rules your kernel may provide.
-
- If you do not want the server to use raw sockets, it is possible to
- configure the Kea DHCPv4 server to use UDP sockets instead. See dhcp-socket-type
- described in . However,
- using UDP sockets has certain limitations. In particular, they may not allow
- for sending responses directly to clients without IPv4 addresses assigned.
- That's ok, if all your traffic is coming through relay agents.
-
-
-
-
-
- Frequently Asked Questions about DHCPv6
-
-
- Kea DHCPv6 doesn't seem to get incoming traffic. I checked with tcpdump (or other traffic
- capture software) that the incoming traffic is reaching the box. What's wrong?
-
- Please check whether your OS has any IPv6 filtering rules. Many
- operating systems are shipped with firewalls that discard incoming IPv6
- traffic by default. In particular, many Linux distributions do that. Please
- check the output of the following command:
-
-# ip6tables -L -n
- One common mistake in this area is to use iptables tool,
- which lists IPv4 firewall rules only.
