29 <cmd>@pkgsysconfdir@/avahi-daemon.conf</cmd>
33 <p><file>avahi-daemon.conf</file> is the configuration file for avahi-daemon.</p>
36 <section name="Section [Server]">
39 <p><opt>host-name=</opt> Set the host name avahi-daemon tries
40 to register on the LAN. If omited defaults to the system host
41 name as set with the sethostname() system call.</p>
45 <p><opt>domain-name=</opt> Set the domain name avahi-domain
46 tries to register its host name and services on the LAN in. If
47 omited defaults to ".local".</p>
51 <p><opt>use-ipv4=</opt> Takes a boolean value ("yes" or
52 "no"). If set to "no" avahi-daemon will not use IPv4
53 sockets. Default is "yes".</p>
57 <p><opt>use-ipv6=</opt> Takes a boolean value ("yes" or
58 "no"). If set to "no" avahi-daemon will not use IPv6
59 sockets. Default is "yes".</p>
63 <p><opt>check-response-ttl=</opt> Takes a boolean value ("yes"
64 or "no"). If set to "yes", an additional security check is
65 activated: incoming IP packets will be ignored unless the IP
66 TTL is 255. Earlier mDNS specifications required this
67 check. Since this feature may be incompatible with newer
68 implementations of mDNS it defaults to "no". On the other hand
69 it provides extra security.</p>
73 <p><opt>use-iff-running=</opt> Takes a boolean value ("yes" or
74 "no"). If set to "yes" avahi-daemon monitors the IFF_RUNNING
75 flag bit which is used by some (modern) network drivers to
76 tell user space if a network cable is plugged in (in case of
77 copper ethernet), or the network card is associated with some
78 kind of network (in case of WLAN). If IFF_RUNNING is set
79 avahi-daemon will automatically announce its services on that
80 network. Unfortunately far too many network drivers do not
81 support this flag or support it in a broken way. Therefore
82 this option defaults to "no".</p>
86 <p><opt>enable-dbus=</opt> Takes either "yes", "no" or
87 "warn". If set to "yes" avahi-daemon connects to D-BUS,
88 offering an object oriented client API. It is only available
89 if avahi has been compiled with <opt>--enable-dbus</opt> in
90 which case it defaults to "yes". "warn" behaves like "yes",
91 but the daemon starts up even when it fails to connect to a
97 <section name="Section [publish]">
99 <p><opt>publish-addresses=</opt> Takes a boolean value ("yes"
100 or "no"). If set to "yes" avahi-daemon will register mDNS
101 address records for all local IP addresses. Unless you want to
102 use avahi-daemon exclusively for browsing it's recommended to
103 enable this. If you plan to register local services you need
104 to enable this option. Defaults to "yes".</p>
108 <p><opt>publish-hinfo=</opt> Takes a boolean value ("yes" or
109 "no"). If set to "yes" avahi-daemon will register an mDNS
110 HINFO record on all interfaces which contains information
111 about the local operating system and CPU, which might be
112 useful for administrative purposes. This is recommended by the
113 mDNS specification but not required. For the sake of privacy
114 you might choose to disable this feature. Defaults to
119 <p><opt>publish-workstation=</opt> Takes a boolean value
120 ("yes" or "no"). If set to "yes" avahi-daemon will register a
121 service of type "_workstation._tcp" on the local LAN. This
122 might be useful for administrative purposes (i.e. browse for
123 all PCs on the LAN), but is not required or recommended by any
124 specification. Newer MacOS X releases register a service of
125 this type. Defaults to "yes".</p>
129 <p><opt>publish-domain=</opt> Takes a boolean value ("yes" or
130 "no"). If set to "yes" avahi-daemon will announce the locally
131 used domain name (see above) for browsing by other
132 hosts. Defaults to "yes".</p>
136 <p><opt>publish-dns-servers=</opt> Takes a comma seperated
137 list of IP addresses for unicast DNS servers. You can use this
138 to announce unicast DNS servers via mDNS. When used in
139 conjunction with avahi-dnsconfd on the client
140 side this allows DHCP-like configuration of unicast DNS
145 <p><opt>publish-resolv-conf-dns-servers=</opt> Takes a boolean
146 value ("yes" or "no"). If set to "yes" avahi-daemon will
147 publish the unicast DNS servers specified in
148 <file>/etc/resolv.conf</file> in addition to those specified
149 with <opt>publish-dns-servers</opt>. Send avahi-daemon a
150 SIGHUP to have it reload this file. Defaults to "no".</p>
155 <section name="Section [reflector]">
157 <p><opt>enable-reflector=</opt> Takes a boolean value ("yes"
158 or "no"). If set to "yes" avahi-daemon will reflect incoming
159 mDNS requests to all local network interfaces, effectively
160 allowing clients to browse mDNS/DNS-SD services on all
161 networks connected to the gateway. The gateway is somewhat
162 intelligent and should work with all kinds of mDNS traffic,
163 though some functionality is lost (specifically the unicast
164 reply bit, which is used rarely anyway). Make sure to not run
165 multiple reflectors between the same networks, this might
166 cause them to play Ping Pong with mDNS packets. Defaults to
171 <p><opt>reflect-ipv=</opt> Takes a boolean value ("yes" or
172 "no"). If set to "yes" and <opt>enable-reflector</opt> is
173 enabled, avahi-daemon will forward mDNS traffic between IPv4
174 and IPv6, which is usually not recommended. Defaults to "no".</p>
178 <section name="Section [rlimits]">
179 <p>This section is used to define system resource limits for the
180 daemon. See <manref section="2" name="setrlimit"/> for more
181 information. If any of the options is not specified in the configuration
182 file, avahi-daemon does not change it from the system
187 <p><opt>rlimit-as=</opt> Value in bytes for RLIMIT_AS (maximum size of the process's virtual memory). Sensible values are heavily system dependent.</p>
191 <p><opt>rlimit-core=</opt> Value in bytes for RLIMIT_CORE (maximum core file size). Unless you want to debug avahi-daemon, it is safe to set this to 0.</p>
195 <p><opt>rlimit-data=</opt> Value in bytes for RLIMIT_DATA (maximum size of the process's data segment). Sensible values are heavily system dependent.</p>
199 <p><opt>rlimit-fsize=</opt> Value for RLIMIT_FSIZE (maximum size of files the process may create). Since avahi-daemon shouldn't write any files to disk, it is safe to set this to 0.</p>
203 <p><opt>rlimit-nofile=</opt> Value for RLIMIT_NOFILE (open file descriptors). avahi-daemon shouldn't need more than 15 to 20 open file descriptors concurrently.</p>
207 <p><opt>rlimit-stack=</opt> Value in bytes for RLIMIT_STACK (maximum size of the process stack). Sensible values are heavily system dependent.</p>
211 <p><opt>rlimit-nproc=</opt> Value for RLIMIT_NPROC (number of process of user). Since only a single avahi-daemon process is usually running you can set this safely to 1.</p>
