RESOLVCONF.CONF(5)

NAME
resolvconf.conf - resolvconf configuration file

DESCRIPTION
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.

After updating this file, you may wish to run resolvconf -u to apply the new configuration.

RESOLVCONF OPTIONS

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 metric. If unset, defaults to the following:-
        tap[0-9]* tun[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]*

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 127.0.0.1 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 0.0.0.0 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.

state_dir
    Override the default state directory of /run/resolvconf. This should not be changed once resolvconf is in use unless the old directory is copied to the new one.

LIBC OPTIONS
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.

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 configured 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.

SUBSCRIBER OPTIONS
openresolv ships with subscribers for the name servers dnsmasq(8), named(8), pdnsd(8) and unbound(8). Each subscriber can create configuration files which should be included in in the subscribers main configuration file.

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=127.0.0.1
        dnsmasq_conf=/etc/dnsmasq-conf.conf
        dnsmasq_resolv=/etc/dnsmasq-resolv.conf

    Example dnsmasq.conf:
        listen-address=127.0.0.1
        # 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 specific domains.

    Example resolvconf.conf for named:
        name_servers=127.0.0.1
        named_options=/etc/named-options.conf
        named_zones=/etc/named-zones.conf

    Example named.conf:
        options {
        listen-on { 127.0.0.1; };
        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 variable is not set then it's written to pdnsd_conf.

    Example resolvconf.conf for pdnsd:
        name_servers=127.0.0.1
        pdnsd_conf=/etc/pdnsd.conf
        # pdnsd_resolv=/etc/pdnsd-resolv.conf

    Example pdnsd.conf:
        global {
        server_ip = 127.0.0.1;
        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.

    Example resolvconf.conf for unbound:
        name_servers=127.0.0.1
        unbound_conf=/etc/unbound-resolvconf.conf

    Example unbound.conf:
        include: /etc/unbound-resolvconf.conf

SUBSCRIBER INTEGRATION
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 automatically 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_reload
    Command to reload the dnsmasq service.

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_reload
    Command to reload the unbound service.

BUGS
Each distribution is a special snowflake and likes to name the same thing differently, namely the named service script.
