|

openresolv 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.

.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.

.Sh HISTORY
|
||||
This implementation of
|
||||
.Nm
|
||||
is called openresolv and is fully command line compatible with Debian's
|
||||
resolvconf, as written by Thomas Hood.
|
||||
.Sh BUGS
|
||||
.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.

.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 updaing 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.
|

|
||||
libc.
|
||||
.It Sy name_servers_append
|
||||
Append name servers to the dynamically generated list.
|
||||
.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

When set to YES the latest resolv.conf is written to
|
||||
.Sy resolv_conf
|
||||
without any alteration.
|
||||
.El
|
||||
.Sh SUBSCRIBER OPTIONS
|
||||
openresolv ships with subscribers for the name servers
|
||||
.Xr dnsmasq 8 ,
|
||||
.Xr named 8 ,
|
||||
.Xr pdnsd 8
|
||||
and
|
||||
.Xr unbound 8 .
|
||||
Each subscriber can create configuration files which should be included in
|
||||
in the subscribers main configuration file.
|

.It Sy pdnsd_conf
|
||||
This is the main pdnsd configuration file which we modify to add our
