6 kea-dhcp4 - DHCPv4 server in Kea

11
13 The kea-dhcp4 daemon provides the DHCPv4 server implementation.
14
16 The arguments are as follows:
17 -v Displays the version.
19 -V Displays the extended version.
21 -W Displays the configuration report.
23 -d Enables the debug mode with extra verbosity.
25 -c config-file
27 Specifies the configuration file with the configuration for the
28 DHCPv4 server. It may also contain configuration entries for
29 other Kea services.
30 -t config-file
32 Checks the configuration file and reports the first error, if
33 any. Note that not all parameters are completely checked; in
34 particular, service and control channel sockets are not opened,
35 and hook libraries are not loaded.
36 -T config-file
38 Checks the configuration file and reports the first error, if
39 any. It performs extra checks beyond what -t offers, such as
40 establishing database connections (for the lease backend, host
41 reservations backend, configuration backend, and forensic log‐
42 ging backend), loading hook libraries, parsing hook-library con‐
43 figurations, etc. It does not open UNIX or TCP/UDP sockets, nor
44 does it open or rotate files, as any of these actions could in‐
45 terfere with a running process on the same machine.
46 -p server-port-number
48 Specifies the server port number (1-65535) on which the server
49 listens. This is useful for testing purposes only.
50 -P client-port-number
52 Specifies the client port number (1-65535) to which the server
53 responds. This is useful for testing purposes only.
54
56 Kea comes with an extensive Kea Administrator Reference Manual that
57 covers all aspects of running the Kea software - compilation, installa‐
58 tion, configuration, configuration examples, and much more. Kea also
59 features a Kea Messages Manual, which lists all possible messages Kea
60 can print with a brief description for each of them. Both documents are
61 available in various formats (.txt, .html, .pdf) with the Kea distribu‐
62 tion. The Kea documentation is available at https://kea.readthedocs.io.
63 Kea source code is documented in the Kea Developer's Guide, available
65 at https://reports.kea.isc.org/dev_guide/.
66 The Kea project website is available at https://kea.isc.org.
68
70 There are two public mailing lists available for the Kea project.
71 kea-users (kea-users at lists.isc.org) is intended for Kea users, while
72 kea-dev (kea-dev at lists.isc.org) is intended for Kea developers,
73 prospective contributors, and other advanced users. Both lists are
74 available at https://lists.isc.org. The community provides best-effort
75 support on both of those lists.
76 ISC provides professional support for Kea services. See
78 https://www.isc.org/kea/ for details.

81 The b10-dhcp4 daemon was first coded in November 2011 by Tomek Mrugal‐
82 ski.
83 In mid-2014, Kea was decoupled from the BIND 10 framework and became a
85 standalone DHCP server. The DHCPv4 server binary was renamed to
86 kea-dhcp4. Kea 1.0.0 was released in December 2015.
