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 nameserver is configured then the default is
just to specify that and ignore all other entries as they will be
configured for the local nameserver. Set this to YES to list them instead,
if you need working DNS and 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 nameservers to use for
specific domains.
- dnsmasq_resolv
- This file tells dnsmasq which nameservers to use for global
lookups.
Example resolvconf.conf for dnsmasq:
nameservers=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
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 nameservers to use for global lookups.
- named_zones
- Include this file in the named global scope, after the
options block. This file tells named which nameservers to use for specific
domains.
Example resolvconf.conf for named:
nameservers=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 nameservers. If this
variable is not set then it's written to pdnsd_conf.
Example resolvconf.conf for pdnsd:
nameservers=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
nameservers.
Example resolvconf.conf for unbound:
nameservers=127.0.0.1
unbound_conf=/etc/unbound-resolvconf.conf
Example unbound.conf:
include: /etc/unbound-resolvconf.conf
