61 make COPTS=-DHAVE_BROKEN_RTC
62
63HAVE_BROKEN_RTC
64 define this on embedded systems which don't have an RTC
65 which keeps time over reboots. Causes dnsmasq to use uptime
66 for timing, and keep lease lengths rather than expiry times
67 in its leases file. This also make dnsmasq "flash disk friendly".
68 Normally, dnsmasq tries very hard to keep the on-disk leases file
69 up-to-date: rewriting it after every renewal. When HAVE_BROKEN_RTC
70 is in effect, the lease file is only written when a new lease is
71 created, or an old one destroyed. (Because those are the only times
72 it changes.) This vastly reduces the number of file writes, and makes
73 it viable to keep the lease file on a flash filesystem.
74 NOTE: when enabling or disabling this, be sure to delete any old
75 leases file, otherwise dnsmasq may get very confused.
76
77HAVE_TFTP
78 define this to get dnsmasq's built-in TFTP server.
79
80HAVE_DHCP
81 define this to get dnsmasq's DHCPv4 server.
82
83HAVE_DHCP6
84 define this to get dnsmasq's DHCPv6 server. (implies HAVE_DHCP).
85
86HAVE_SCRIPT
87 define this to get the ability to call scripts on lease-change.
88
89HAVE_LUASCRIPT
90 define this to get the ability to call Lua script on lease-change. (implies HAVE_SCRIPT)
91
92HAVE_DBUS
93 define this if you want to link against libdbus, and have dnsmasq
94 support some methods to allow (re)configuration of the upstream DNS
95 servers via DBus.
96
97HAVE_IDN
Petr Menšíkd203af42017-05-10 21:41:57 +010098 define this if you want international domain name 2003 support.

Petr Menšíkd203af42017-05-10 21:41:57 +0100100HAVE_LIBIDN2
101 define this if you want international domain name 2008 support.
102
Simon Kelleyc72daea2012-01-05 21:33:27 +0000103HAVE_CONNTRACK
Josh Soref730c6742017-02-06 16:14:04 +0000104 define this to include code which propagates conntrack marks from
Simon Kelleyc72daea2012-01-05 21:33:27 +0000105 incoming DNS queries to the corresponding upstream queries. This adds
106 a build-dependency on libnetfilter_conntrack, but the resulting binary will
107 still run happily on a kernel without conntrack support.
108
Jason A. Donenfeld13d86c72013-02-22 18:20:53 +0000109HAVE_IPSET
110 define this to include the ability to selectively add resolved ip addresses
111 to given ipsets.
112
Simon Kelley4820dce2012-12-18 18:30:30 +0000113HAVE_AUTH
114 define this to include the facility to act as an authoritative DNS
115 server for one or more zones.
116
Simon Kelley063efb32014-06-17 19:49:31 +0100117HAVE_DNSSEC
118 include DNSSEC validator.
Simon Kelley4820dce2012-12-18 18:30:30 +0000119
Simon Kelley6b173352018-05-08 18:32:14 +0100120HAVE_DUMPFILE
121 include code to dump packets to a libpcap-format file for debugging.
122
Simon Kelleyb5ea1cc2014-07-29 16:34:14 +0100123HAVE_LOOP
124 include functionality to probe for and remove DNS forwarding loops.
125
Simon Kelley04918052015-01-26 11:23:43 +0000126HAVE_INOTIFY
127 use the Linux inotify facility to efficiently re-read configuration files.
Simon Kelleyb5ea1cc2014-07-29 16:34:14 +0100128
Kevin Darbyshire-Bryant7ac9ae12016-09-09 20:52:08 +0100129NO_ID

142 which are enabled by default in the distributed source tree. Building dnsmasq
143 with something like "make COPTS=-DNO_SCRIPT" will do the trick.
