openresolv-3.5.6/README000064400000000000000000000011241217003070200145650ustar00rootroot00000000000000openresolv is a resolvconf implementation which manages resolv.conf
You can find the latest version at http://roy.marples.name/projects/openresolv
It is written and maintained by Roy Marples <roy@marples.name>

This resolvconf implementation, along with its subscribers, work with a
POSIX compliant shell and userland utilities. It is designed to work without
tools such as sed as it *has* to work without /usr being available.

On systems where resolvconf is expected to be used before /var/run is available
for writing, you can configure openresolv to write somewhere else, like say a
ramdisk.

.Dt RESOLVCONF 8 SMM
.Os
.Sh NAME
.Nm resolvconf
.Nd a framework for managing multiple DNS configurations
.Sh SYNOPSIS
.Nm
.Fl I
.Nm
.Op Fl m Ar metric
.Op Fl p
.Fl a Ar interface No < Ns Pa file
.Nm
.Op Fl f
.Fl d Ar interface
.Nm
.Fl il Ar pattern
.Nm
.Fl u
.Sh DESCRIPTION
.Nm
manages
.Xr resolv.conf 5
files from multiple sources, such as DHCP and VPN clients.
Traditionally, the host runs just one client and that updates
.Pa /etc/resolv.conf .
More modern systems frequently have wired and wireless interfaces and there is
no guarantee both are on the same network.
With the advent of VPN and other
types of networking daemons, many things now contend for the contents of
.Pa /etc/resolv.conf .
.Pp
.Nm
solves this by letting the daemon send their
.Xr resolv.conf 5
file to
.Nm
via
.Xr stdin 3
with the argument
.Fl a Ar interface
instead of the filesystem.
.Nm
then updates
.Pa /etc/resolv.conf
as it thinks best.
When a local resolver other than libc is installed, such as
.Xr dnsmasq 8
or
.Xr named 8 ,
then
.Nm
will supply files that the resolver should be configured to include.
.Pp
.Nm
can mark an interfaces
.Pa resolv.conf
as private.
This means that the name servers listed in that
.Pa resolv.conf
are only used for queries against the domain/search listed in the same file.
This only works when a local resolver other than libc is installed. 
See
.Xr resolvconf.conf 5
for how to configure
.Nm
to use a local name server.
.Pp
When an interface goes down, it should then call
.Nm
with
.Fl d Ar interface
arguments to delete the
.Pa resolv.conf
file for the
.Ar interface .
.Pp
Here are some more options that
.Nm
has:-
.Bl -tag -width indent
.It Fl I
Initialise the state directory
.Pa @VARDIR@ .
This only needs to be called if the initial system boot sequence does not
automatically clean it out; for example the state directory is moved
somewhere other than
.Pa /var/run .
If used, it should only be called once as early in the system boot sequence
as possible and before
.Nm
is used to add interfaces.
.It Fl f
Ignore non existant interfaces.
Only really useful for deleting interfaces.
.It Fl i Ar pattern
List the interfaces, optionally matching
.Ar pattern ,
we have
.Pa resolv.conf
files for.
.It Fl l Ar pattern
List the
.Pa resolv.conf
files we have.
If
.Ar pattern
is specified then we list the files for the interfaces that match it.
.It Fl m Ar metric
Set the metric of the interface when adding it, default of 0.
Lower metrics take precedence.
This affects the default order of interfaces when listed.
.It Fl p
Marks the interface
.Pa resolv.conf
as private.
.It Fl u
Force
.Nm
to update all it's subscribers.
.Nm
does not update the subscribers when adding a resolv.conf that matches
what it already has for that interface.
.El
.Pp
.Nm
also has some options designed to be used by it's subscribers:-
.Bl -tag -width indent
.It Fl v
Echo variables DOMAINS, SEARCH and NAMESERVERS so that the subscriber can
configure the resolver easily.
.El
.Sh INTERFACE ORDERING
For
.Nm
to work effectively, it has to process the resolv.confs for the interfaces
in the correct order.
.Nm
first processes interfaces from the
.Sy interface_order
list, then interfaces without a metic and that match the
.Sy dynamic_order
list, then interfaces with a metric in order and finally the rest in
the operating systems lexical order.
See
.Xr resolvconf.conf 5
for details on these lists.
.Sh IMPLEMENTATION NOTES
If a subscriber has the executable bit then it is executed otherwise it is
assumed to be a shell script and sourced into the current environment in a
subshell.
This is done so that subscribers can remain fast, but are also not limited
to the shell language.
.Pp
Portable subscribers should not use anything outside of
.Pa /bin
and
.Pa /sbin
because
.Pa /usr
and others may not be available when booting.
Also, it would be unwise to assume any shell specific features.
.Sh ENVIRONMENT
.Bl -ohang
.It Va IF_METRIC
If the
.Fl m
option is not present then we use
.Va IF_METRIC
for the metric.
.It Va IF_PRIVATE
Marks the interface
.Pa resolv.conf
as private.
.El
.Sh FILES
.Bl -ohang
.It Pa @SYSCONFDIR@/resolvconf.conf
Configuration file for
.Nm .
.It Pa @LIBEXECDIR@
Directory of subscribers which are run every time
.Nm
adds, deletes or updates.
.It Pa @LIBEXECDIR@/libc.d
Directory of subscribers which are run after the libc subscriber is run.
.It Pa @VARDIR@
State directory for
.Nm .
.El
.Sh HISTORY
This implementation of
.Nm
is called openresolv and is fully command line compatible with Debian's
resolvconf, as written by Thomas Hood.

.Nm
does not validate any of the files given to it.
.Pp
When running a local resolver other than libc, you will need to configure it
to include files that
.Nm
will generate.
You should consult
.Xr resolvconf.conf 5
for instructions on how to configure your resolver.

.Dt RESOLVCONF.CONF 5 SMM
.Os
.Sh NAME
.Nm resolvconf.conf
.Nd resolvconf configuration file
.Sh DESCRIPTION
.Nm
is the configuration file for
.Xr resolvconf 8 .
The
.Nm
file is a shell script that is sourced by
.Xr resolvconf 8 ,
meaning that
.Nm
must contain valid shell commands.
Listed below are the standard
.Nm
variables that may be set.
.Pp
After updating this file, you may wish to run
.Nm resolvconf -u
to apply the new configuration.
.Sh RESOLVCONF OPTIONS
.Bl -tag -width indent
.It Sy interface_order
These interfaces will always be processed first.
If unset, defaults to the following:-
.D1 lo lo[0-9]*
.It Sy dynamic_order
These interfaces will be processed next, unless they have a metric.
If unset, defaults to the following:-
.D1 tap[0-9]* tun[0-9]* vpn vpn[0-9]* ppp[0-9]* ippp[0-9]*
.It Sy search_domains
Prepend search domains to the dynamically generated list.
.It Sy search_domains_append
Append search domains to the dynamically generated list.
.It Sy 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
.It Sy 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.
.It Sy name_servers_append
Append name servers to the dynamically generated list.
.It Sy 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.*
.It Sy 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
.Nm resolvconf -p
option.
.It Sy state_dir
Override the default state directory of
.Pa @VARDIR@ .
This should not be changed once
.Nm resolvconf
is in use unless the old directory is copied to the new one.
.El
.Sh LIBC OPTIONS
The following variables affect
.Xr resolv.conf 5
directly:-
.Bl -tag -width indent
.It Sy resolv_conf
Defaults to
.Pa /etc/resolv.conf
if not set.
.It Sy resolv_conf_options
A list of libc resolver options, as specified in
.Xr resolv.conf 5 .
.It Sy resolv_conf_passthrough
When set to YES the latest resolv.conf is written to
.Sy resolv_conf
without any alteration.
.It Sy resolv_conf_sortlist
A libc resolver sortlist, as specified in
.Xr resolv.conf 5 .
.It Sy 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.
.El
.Sh SUBSCRIBER OPTIONS
openresolv ships with subscribers for the name servers
.Xr dnsmasq 8 ,
.Xr named 8 ,

Each subscriber can create configuration files which should be included in
in the subscribers main configuration file.
.Bl -tag -width indent
.It Sy dnsmasq_conf
This file tells dnsmasq which name servers to use for specific domains.
.It Sy dnsmasq_resolv
This file tells dnsmasq which name servers to use for global lookups.
.Pp
Example resolvconf.conf for dnsmasq:
.D1 name_servers=127.0.0.1
.D1 dnsmasq_conf=/etc/dnsmasq-conf.conf
.D1 dnsmasq_resolv=/etc/dnsmasq-resolv.conf
.Pp
Example dnsmasq.conf:
.D1 listen-address=127.0.0.1
.D1 # If dnsmasq is compiled for DBus then we can take
.D1 # advantage of not having to restart dnsmasq.
.D1 enable-dbus
.D1 conf-file=/etc/dnsmasq-conf.conf
.D1 resolv-file=/etc/dnsmasq-resolv.conf
.It Sy named_options
Include this file in the named options block.
This file tells named which name servers to use for global lookups.
.It Sy 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.
.Pp
Example resolvconf.conf for named:
.D1 name_servers=127.0.0.1
.D1 named_options=/etc/named-options.conf
.D1 named_zones=/etc/named-zones.conf
.Pp
Example named.conf:
.D1 options {
.D1 	listen-on { 127.0.0.1; };
.D1 	include "/etc/named-options.conf";
.D1 };
.D1 include "/etc/named-zones.conf";
.It Sy 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
.Pa pdnsd_resolv
as documented below.
.It Sy pdnsd_resolv
This file tells pdnsd about global name servers.
If this variable is not set then it's written to
.Pa pdnsd_conf .
.Pp
Example resolvconf.conf for pdnsd:
.D1 name_servers=127.0.0.1
.D1 pdnsd_conf=/etc/pdnsd.conf
.D1 # pdnsd_resolv=/etc/pdnsd-resolv.conf
.Pp
Example pdnsd.conf:
.D1 global {
.D1 	server_ip = 127.0.0.1;
.D1 	status_ctl = on;
.D1 }
.D1 server {
.D1 	# A server definition is required, even if emtpy.
.D1 	label="empty";
.D1 	proxy_only=on;
.D1 	# file="/etc/pdnsd-resolv.conf";
.D1 }
.It Sy unbound_conf
This file tells unbound about specific and global name servers.
.Pp
Example resolvconf.conf for unbound:
.D1 name_servers=127.0.0.1
.D1 unbound_conf=/etc/unbound-resolvconf.conf
.Pp
Example unbound.conf:
.D1 include: /etc/unbound-resolvconf.conf

.Sh 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.
.Pp
.Bl -tag -width indent
.It Sy dnsmasq_service
Location of the dnsmasq service.
.It Sy dnsmasq_restart
Command to restart the dnsmasq service.
.It Sy dnsmasq_pid
Location of the dnsmasq pidfile.
.It Sy libc_service
Location of the libc service.
.It Sy libc_restart
Command to restart the libc service.
.It Sy named_service
Location of the named service.
.It Sy named_restart
Command to restart the named service.
.It Sy pdnsd_restart
Command to restart the pdnsd service.
.It Sy unbound_service
Location of the unbound service.
.It Sy unbound_restart
Command to restart the unbound service.
.It Sy unbound_pid
Location of the unbound pidfile.
