1 Q: Why does dnsmasq open UDP ports >1024 as well as port 53.
4 A: The high ports that dnsmasq opens are for replies from the upstream
5 nameserver(s). Queries from dnsmasq to upstream nameservers are sent
8 to stop DNS queries from the outside world. If dnsmasq sent its queries
11 This is not a security hole since dnsmasq will only accept replies to that
13 which dnsmasq has forwarded, otherwise they are dropped too.
15 Addendum: dnsmasq now has the option "query-port" (-Q), which allows
21 DNS protocol, dnsmasq from version 2.43 has changed behavior. It

57 ports and building dnsmasq with "make MAKE=gmake"
62 dosen't work: dnsmasq seems not to use the nameservers in the order
65 A: By default, dnsmasq treats all the nameservers it knows about as
67 nameservers which aren't responding. To make dnsmasq use the
70 IP address of that server, and telling dnsmasq exactly which

163 note the IP address being returned and pass it to dnsmasq using the
176 encountered by people moving from the ISC dhcpd to the dnsmasq
179 IP configuration and can lead to the dnsmasq daemon failing
194 that the current configuration is OK for the dnsmasq daemon.
195 For the dnsmasq daemon to operate it's vital that UDP packets to
224 without a client ID.) dnsmasq therefore has to give the machine a
230 "dhcp-host=id:01:11:22:33:44:55:66,1.2.3.4" or (3) tell dnsmasq to
249 everything works. This is the how dnsmasq works when
279 wildcard binding means that dnsmasq will quite happily start up
281 created later. Wildcard binding breaks the scenario when dnsmasq is
284 (address,port) pair when dnsmasq has bound (wildcard,port), hence
295 Q: Can I get email notification when a new version of dnsmasq is
298 A: Yes, new releases of dnsmasq are always announced through

307 for the ISC daemon, but the same applies to dnsmasq.
315 a lease which is long gone, as far as dnsmasq is concerned, and
316 dnsmasq ignores it until is times out and restarts the process.
317 To fix this, set the dhcp-authoritative flag in dnsmasq.
336 From version 2.46, dnsmasq has a solution to this which doesn't
338 address in a --dhcp-host configuration. This tells dnsmasq that it
340 and furthermore it gives dnsmasq permission to sumarily abandon a
343 up at any time. There is no way for dnsmasq to enforce this
347 Q: Can dnsmasq do DHCP on IP-alias interfaces?
372 dnsmasq as an upstream server and should be removed from the
374 nameserver configured dnsmasq will load-balance across them and
375 it may be some time before dnsmasq gets around to using a

390 the address probe may be skipped when dnsmasq is under heavy load.

414 remove the need to set capabilities by running dnsmasq as root.
422 Q: Can I run dnsmasq in a Linux vserver?
424 A: Yes, as a DNS server, dnsmasq will just work in a vserver.
425 To use dnsmasq's DHCP function you need to give the vserver
438 Q: What's the problem with syslog and dnsmasq?
446 dnsmasq, which also sends log messages. With bad timing, you can
447 arrive at a situation where syslog is waiting for dnsmasq, and
448 dnsmasq is waiting for syslog; they will both wait forever. This
449 problem is fixed from dnsmasq-2.39, which introduces asynchronous
450 logging: dnsmasq no longer waits for syslog and the deadlock is
