resolvconf.conf -- resolvconf configuration file
resolvconf.conf is the configuration file for resolvconf(8). The resolvconf.conf file is a shell script that is sourced by resolvconf(8), meaning that resolvconf.conf must contain valid shell commands. Listed below are the standard resolvconf.conf variables that may be set. If the values contain white space for special shell characters, ensure they are quoted and escaped correctly. After updating this file, you may wish to run resolvconf -u to apply the new configuration. When a dynmically generated list is appended or prepended to, the whole is made unique where left-most wins.
resolvconf Set to NO to disable resolvconf from running any subscribers. Defaults to YES. interface_order These interfaces will always be processed first. If unset, defaults to the following:- lo lo[0-9]* dynamic_order These interfaces will be processed next, unless they have a met- ric. If unset, defaults to the following:- tap[0-9]* tun[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]* local_nameservers If unset, defaults to the following:- 127.* ::1 search_domains Prepend search domains to the dynamically generated list. search_domains_append Append search domains to the dynamically generated list. domain_blacklist A list of domains to be removed from consideration. To remove a domain, you can use foo.* To remove a sub domain, you can use *.bar name_servers Prepend name servers to the dynamically generated list. You should set this to if you use a local name server other than libc. name_servers_append Append name servers to the dynamically generated list. name_server_blacklist A list of name servers to be removed from consideration. The default is as some faulty routers send it via DHCP. To remove a block, you can use 192.168.* private_interfaces These interfaces name servers will only be queried for the domains listed in their resolv.conf. Useful for VPN domains. This is equivalent to the resolvconf -p option. replace Is a space separated list of replacement keywords. The syntax is this: $keyword/$match/$replacement Example, given this resolv.conf: domain search dead.beef nameserver nameserver and this configuaration: replace="search/foo*/ nameserver/ nameserver/" you would get this resolv.conf instead: domain search nameserver replace_sub Works the same way as replace except it works on each space sepa- rated value rather than the whole line, so it's useful for the replacing a single domain within the search directive. Using the same example resolv.conf and changing replace to replace_sub, you would get this resolv.conf instead: domain search dead.beef nameserver state_dir Override the default state directory of /var/run/resolvconf. This should not be changed once resolvconf is in use unless the old directory is copied to the new one.
The following variables affect resolv.conf(5) directly:- resolv_conf Defaults to /etc/resolv.conf if not set. resolv_conf_options A list of libc resolver options, as specified in resolv.conf(5). resolv_conf_passthrough When set to YES the latest resolv.conf is written to resolv_conf without any alteration. When set to /dev/null or NULL, resolv_conf_local_only is defaulted to NO, local_nameservers is unset unless overriden and only the information set in resolvconf.conf is written to resolv_conf. resolv_conf_sortlist A libc resolver sortlist, as specified in resolv.conf(5). resolv_conf_local_only If a local name server is configured then the default is just to specify that and ignore all other entries as they will be config- ured for the local name server. Set this to NO to also list non- local nameservers. This will give you working DNS even if the local nameserver stops functioning at the expense of duplicated server queries. append_nameservers Append name servers to the dynamically generated list. prepend_nameservers Prepend name servers to the dynamically generated list. append_search Append search domains to the dynamically generated list. prepend_search Prepend search domains to the dynamically generated list.
openresolv ships with subscribers for the name servers dnsmasq(8), named(8), pdnsd(8) and unbound(8). Each subscriber can create configura- tion files which should be included in in the subscribers main configura- tion file. To disable a subscriber, simply set it's name to NO. For example, to disable the libc subscriber you would set: libc=NO dnsmasq_conf This file tells dnsmasq which name servers to use for specific domains. dnsmasq_resolv This file tells dnsmasq which name servers to use for global lookups. Example resolvconf.conf for dnsmasq: name_servers= dnsmasq_conf=/etc/dnsmasq-conf.conf dnsmasq_resolv=/etc/dnsmasq-resolv.conf Example dnsmasq.conf: listen-address= # If dnsmasq is compiled for DBus then we can take # advantage of not having to restart dnsmasq. enable-dbus conf-file=/etc/dnsmasq-conf.conf resolv-file=/etc/dnsmasq-resolv.conf named_options Include this file in the named options block. This file tells named which name servers to use for global lookups. named_zones Include this file in the named global scope, after the options block. This file tells named which name servers to use for spe- cific domains. Example resolvconf.conf for named: name_servers= named_options=/etc/named-options.conf named_zones=/etc/named-zones.conf Example named.conf: options { listen-on {; }; include /etc/named-options.conf; }; include /etc/named-zones.conf; pdnsd_conf This is the main pdnsd configuration file which we modify to add our forward domains to. If this variable is not set then we rely on the pdnsd configuration file setup to read pdnsd_resolv as documented below. pdnsd_resolv This file tells pdnsd about global name servers. If this vari- able is not set then it's written to pdnsd_conf. Example resolvconf.conf for pdnsd: name_servers= pdnsd_conf=/etc/pdnsd.conf # pdnsd_resolv=/etc/pdnsd-resolv.conf Example pdnsd.conf: global { server_ip =; status_ctl = on; } server { # A server definition is required, even if emtpy. label="empty"; proxy_only=on; # file="/etc/pdnsd-resolv.conf"; } unbound_conf This file tells unbound about specific and global name servers. unbound_insecure When set to YES, unbound marks the domains as insecure, thus ignoring DNSSEC. Example resolvconf.conf for unbound: name_servers= unbound_conf=/etc/unbound-resolvconf.conf Example unbound.conf: include: /etc/unbound-resolvconf.conf
Not all distributions store the files the subscribers need in the same locations. For example, named service scripts have been called named, bind and rc.bind and they could be located in a directory called /etc/rc.d, /etc/init.d or similar. Each subscriber attempts to automati- cally configure itself, but not every distribution has been catered for. Also, users could equally want to use a different version from the one installed by default, such as bind8 and bind9. To accomodate this, the subscribers have these files in configurable variables, documented below. dnsmasq_service Location of the dnsmasq service. dnsmasq_restart Command to restart the dnsmasq service. dnsmasq_pid Location of the dnsmasq pidfile. libc_service Location of the libc service. libc_restart Command to restart the libc service. named_service Location of the named service. named_restart Command to restart the named service. pdnsd_restart Command to restart the pdnsd service. unbound_service Location of the unbound service. unbound_restart Command to restart the unbound service. unbound_pid Location of the unbound pidfile.
resolv.conf(5), resolvconf(8) and sh(1).

Each distribution is a special snowflake and likes to name the same thing differently, namely the named service script. Please report them to NetBSD 7.0 October 28, 2014 NetBSD 7.0
