Q: Why do we get the following warning at run time:
kernel: process `named' is using obsolete setsockopt SO_BSDCOMPAT
A: The early Linux kernels broke sendto() by having it return that a ICMP
unreachable had be received for non connected UDP sockets. This made non
connected UDP sockets work like connected UDP socket which is fine when you are
only talking to one destination. Named however talks to multiple destinations
and it caused problems.
Rather than fix sendto() to just have BSD behaviour they added SO_BSDCOMPAT to
turn BSD behaviour on/off on a per socket basis.
Later they decided to make BSD behaviour the default and to aggressively track
down applications that used SO_BSDCOMPAT by issuing a warning. This is the sort
of things vendors do in alpha/beta stages of a release so that their code is
clean. They then turn the warning *off* for release code.
We still have customers that have kernels that require SO_BSDCOMPAT to operate.
We therefore cannot remove the setsockopt(SO_BSDCOMPAT) call.
Now most/all portable applications that use SO_BSDCOMPAT use it conditionally
manner so just removing SO_BSDCOMPAT from the header file would be safe as long
as the binary was not to be moved between systems. BIND's use is conditional.
In short, the Linux developers should either, remove the #define for
SO_BSDCOMPAT, and/or remove the warning.
Q: Isn't "make install" supposed to generate a default named.conf?
A: Short Answer: No.
Long Answer: There really isn't a default configuration which fits any site
perfectly. There are lots of decisions that need to be made and there is no
consensus on what the defaults should be. For example FreeBSD uses /etc/namedb
as the location where the configuration files for named are stored. Others use
/var/named.
What addresses to listen on? For a laptop on the move a lot you may only want
to listen on the loop back interfaces.
Who do you offer recursive service to? Is there are firewall to consider? If so
is it stateless or stateful. Are you directly on the Internet? Are you on a
private network? Are you on a NAT'd network? The answers to all these questions
change how you configure even a caching name server.

BIND 9.4.0
BIND 9.3.1
BIND 9.4.0 has a number of new features over 9.3,
including:
BIND 9.3.1 is a maintenance release, containing fixes for
a number of bugs in 9.3.0.
Implemented "additional section caching" (or "acache"), an
internal cache framework for additional section content to
improve response performance. Several configuration options
were provided to control the behavior.
libbind: corresponds to that from BIND 8.4.6-REL.
New notify type 'master-only'. Enable notify for master
zones only.
Accept 'notify-source' style syntax for query-source.
rndc now allows addresses to be set in the server clauses.
New option "allow-query-cache". This lets allow-query be
used to specify the default zone access level rather than
having to have every zone override the global value.
allow-query-cache can be set at both the options and view
levels. If allow-query-cache is not set allow-query applies.
rndc: the source address can now be specified.
ixfr-from-differences now takes master and slave in addition
to yes and no at the options and view levels.
Allow the journal's name to be changed via named.conf.
'rndc notify zone [class [view]]' resend the NOTIFY messages
for the specified zone.
'dig +trace' now randomly selects the next servers to try.
Report if there is a bad delegation.
Improve check-names error messages.
Make public the function to read a key file, dst_key_read_public().
dig now returns the byte count for axfr/ixfr.
allow-update is now settable at the options / view level.
named-checkconf now checks the logging configuration.
host now can turn on memory debugging flags with '-m'.
Don't send notify messages to self.
Perform sanity checks on NS records which refer to 'in zone' names.
New zone option "notify-delay". Specify a minimum delay
between sets of NOTIFY messages.
Extend adjusting TTL warning messages.
Named and named-checkzone can now both check for non-terminal
wildcard records.
"rndc freeze/thaw" now freezes/thaws all zones.
named-checkconf now check acls to verify that they only
refer to existing acls.
The server syntax has been extended to support a range of
servers.
Report differences between hints and real NS rrset and
associated address records.
Preserve the case of domain names in rdata during zone
transfers.
Restructured the data locking framework using architecture
dependent atomic operations (when available), improving
response performance on multi-processor machines significantly.
x86, x86_64, alpha, powerpc, and mips are currently supported.
UNIX domain controls are now supported.
Add support for additional zone file formats for improving
loading performance. The masterfile-format option in
named.conf can be used to specify a non-default format. A
separate command named-compilezone was provided to generate
zone files in the new format. Additionally, the -I and -O
options for dnssec-signzone specify the input and output
formats.
dnssec-signzone can now randomize signature end times
(dnssec-signzone -j jitter).
Add support for CH A record.
Add additional zone data consistancy checks. named-checkzone
has extended checking of NS, MX and SRV record and the hosts
they reference. named has extended post zone load checks.
New zone options: check-mx and integrity-check.
edns-udp-size can now be overridden on a per server basis.
dig can now specify the EDNS version when making a query.
Added framework for handling multiple EDNS versions.
Additional memory debugging support to track size and mctx
arguments.
Detect duplicates of UDP queries we are recursing on and
drop them. New stats category "duplicates".
Memory management. "USE INTERNAL MALLOC" is now runtime selectable.
The lame cache is now done on a <qname,qclass,qtype> basis
as some servers only appear to be lame for certain query
types.
Limit the number of recursive clients that can be waiting
for a single query (<qname,qtype,qclass>) to resolve. New
options clients-per-query and max-clients-per-query.
dig: report the number of extra bytes still left in the
packet after processing all the records.
Support for IPSECKEY rdata type.
Raise the UDP receive buffer size to 32k if it is less than 32k.
x86 and x86_64 now have separate atomic locking implementations.
named-checkconf now validates update-policy entries.
Attempt to make the amount of work performed in a iteration
self tuning. The covers nodes clean from the cache per
iteration, nodes written to disk when rewriting a master
file and nodes destroyed per iteration when destroying a
zone or a cache.
ISC string copy API.
Automatic empty zone creation for D.F.IP6.ARPA and friends.
Note: RFC 1918 zones are not yet covered by this but are
likely to be in a future release.
New options: empty-server, empty-contact, empty-zones-enable
and disable-empty-zone.
dig now has a '-q queryname' and '+showsearch' options.
host/nslookup now continue (default)/fail on SERVFAIL.
dig now warns if 'RA' is not set in the answer when 'RD'
was set in the query. host/nslookup skip servers that fail
to set 'RA' when 'RD' is set unless a server is explicitly
set.
Integrate contributed DLZ code into named.
Integrate contributed IDN code from JPNIC.
Validate pending NS RRsets, in the authority section, prior
to returning them if it can be done without requiring DNSKEYs
to be fetched.
It is now possible to configure named to accept expired
RRSIGs. Default "dnssec-accept-expired no;". Setting
"dnssec-accept-expired yes;" leaves named vulnerable to
replay attacks.
Additional memory leakage checks.
The maximum EDNS UDP response named will send can now be
set in named.conf (max-udp-size). This is independent of
the advertised receive buffer (edns-udp-size).
Named now falls back to advertising EDNS with a 512 byte
receive buffer if the initial EDNS queries fail.
Control the zeroing of the negative response TTL to a soa
query. Defaults "zero-no-soa-ttl yes;" and
"zero-no-soa-ttl-cache no;".
Separate out MX and SRV to CNAME checks.
dig/nslookup/host: warn about missing "QR".
TSIG HMACSHA1, HMACSHA224, HMACSHA256, HMACSHA384 and
HMACSHA512 support.
dnssec-signzone: output the SOA record as the first record
in the signed zone.
Two new update policies. "selfsub" and "selfwild".
dig, nslookup and host now advertise a 4096 byte EDNS UDP
buffer size by default.
Report when a zone is removed.
DS/DLV SHA256 digest algorithm support.
Implement "rrset-order fixed".
Check the KSK flag when updating a secure dynamic zone.
New zone option "update-check-ksk yes;".
It is now possible to explicitly enable DNSSEC validation.
default dnssec-validation no; to be changed to yes in 9.5.0.
It is now possible to enable/disable DNSSEC validation
from rndc. This is useful for the mobile hosts where the
current connection point breaks DNSSEC (firewall/proxy).
rndc validation newstate [view]
dnssec-signzone can now update the SOA record of the signed
zone, either as an increment or as the system time().
Statistics about acache now recorded and sent to log.

dig/host/nslookup accepts non-ASCII domain names in the local
codeset (such as Shift JIS, Big5 or ISO8859-1) determined by
the locale information. The domain names are normalized and
converted to the encoding on the DNS protocol, and sent to DNS
servers. The replies are converted back to the local codeset
and displayed.
* Compilation & installation
0. Prerequisite
You have to build and install idnkit before building this patched version
of bind-9.
1. Running configure script
Run `configure' in the top directory. See `README' for the
configuration options.
This patch adds the following 4 options to `configure'. You should
at least specify `--with-idn' option to enable IDN support.
--with-idn[=IDN_PREFIX]
To enable IDN support, you have to specify `--with-idn' option.
The argument IDN_PREFIX is the install prefix of idnkit. If
IDN_PREFIX is omitted, PREFIX (derived from `--prefix=PREFIX')
is assumed.
--with-libiconv[=LIBICONV_PREFIX]
Specify this option if idnkit you have installed links GNU
libiconv. The argument LIBICONV_PREFIX is install prefix of
GNU libiconv. If the argument is omitted, PREFIX (derived
from `--prefix=PREFIX') is assumed.
`--with-libiconv' is shorthand option for GNU libiconv.
--with-libiconv=/usr/local
This is equivalent to:
--with-iconv='-L/usr/local/lib -R/usr/local/lib -liconv'
`--with-libiconv' assumes that your C compiler has `-R'
option, and that the option adds the specified run-time path
to an exacutable binary. If `-R' option of your compiler has
different meaning, or your compiler lacks the option, you
should use `--with-iconv' option instead. Binary command
without run-time path information might be unexecutable.
In that case, you would see an error message like:
error in loading shared libraries: libiconv.so.2: cannot
open shared object file
If both `--with-libiconv' and `--with-iconv' options are
specified, `--with-iconv' is prior to `--with-libiconv'.
--with-iconv=ICONV_LIBSPEC
If your libc doens't provide iconv(), you need to specify the
library containing iconv() with this option. `ICONV_LIBSPEC'
is the argument(s) to `cc' or `ld' to link the library, for
example, `--with-iconv="-L/usr/local/lib -liconv"'.
You don't need to specify the header file directory for "iconv.h"
to the compiler, as it isn't included directly by bind-9 with
this patch.
--with-idnlib=IDN_LIBSPEC
With this option, you can explicitly specify the argument(s)
to `cc' or `ld' to link the idnkit's library, `libidnkit'. If
this option is not specified, `-L${PREFIX}/lib -lidnkit' is
assumed, where ${PREFIX} is the installation prefix specified
with `--with-idn' option above. You may need to use this
option to specify extra argments, for example,
`--with-idnlib="-L/usr/local/lib -R/usr/local/lib -lidnkit"'.
Please consult `README' for other configuration options.
Note that if you want to specify some extra header file directories,
you should use the environment variable STD_CINCLUDES instead of
CFLAGS, as described in README.
2. Compilation and installation
After running "configure", just do
make
make install
for compiling and installing.

.SH "DESCRIPTION"
.PP
\fBnamed\-checkzone\fR
@ -42,64 +44,211 @@ checks the syntax and integrity of a zone file. It performs the same checks as
does when loading a zone. This makes
\fBnamed\-checkzone\fR
useful for checking zone files before configuring them into a name server.
.PP
\fBnamed\-compilezone\fR
is similar to
\fBnamed\-checkzone\fR, but it always dumps the zone contents to a specified file in a specified format. Additionally, it applies stricter check levels by default, since the dump output will be used as an actual zone file loaded by
\fBnamed\fR. When manaully specified otherwise, the check levels must at least be as strict as those specified in the
\fBnamed\fR
configuration file.
.SH "OPTIONS"
.TP 3n
.PP
\-d
.RS 4
Enable debugging.
.TP 3n
.RE
.PP
\-q
.RS 4
Quiet mode \- exit code only.
.TP 3n
.RE
.PP
\-v
.RS 4
Print the version of the
\fBnamed\-checkzone\fR
program and exit.
.TP 3n
.RE
.PP
\-j
.RS 4
When loading the zone file read the journal if it exists.
.TP 3n
.RE
.PP
\-c \fIclass\fR
.RS 4
Specify the class of the zone. If not specified "IN" is assumed.
.TP 3n
.RE
.PP
\-i \fImode\fR
.RS 4
Perform post load zone integrity checks. Possible modes are
\fB"full"\fR
(default),
\fB"full\-sibling"\fR,
\fB"local"\fR,
\fB"local\-sibling"\fR
and
\fB"none"\fR.
.sp
Mode
\fB"full"\fR
checks that MX records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). Mode
\fB"local"\fR
only checks MX records which refer to in\-zone hostnames.
.sp
Mode
\fB"full"\fR
checks that SRV records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). Mode
\fB"local"\fR
only checks SRV records which refer to in\-zone hostnames.
.sp
Mode
\fB"full"\fR
checks that delegation NS records refer to A or AAAA record (both in\-zone and out\-of\-zone hostnames). It also checks that glue addresses records in the zone match those advertised by the child. Mode
\fB"local"\fR
only checks NS records which refer to in\-zone hostnames or that some required glue exists, that is when the nameserver is in a child zone.
.sp
Mode
\fB"full\-sibling"\fR
and
\fB"local\-sibling"\fR
disable sibling glue checks but are otherwise the same as
\fB"full"\fR
and
\fB"local"\fR
respectively.
.sp
Mode
\fB"none"\fR
disables the checks.
.RE
.PP
\-f \fIformat\fR
.RS 4
Specify the format of the zone file. Possible formats are
\fB"text"\fR
(default) and
\fB"raw"\fR.
.RE
.PP
\-F \fIformat\fR
.RS 4
Specify the format of the output file specified. Possible formats are
\fB"text"\fR
(default) and
\fB"raw"\fR. For
\fBnamed\-checkzone\fR, this does not cause any effects unless it dumps the zone contents.
.RE
.PP
\-k \fImode\fR
.RS 4
Perform
\fB"check\-names"\fR
checks with the specified failure mode. Possible modes are
\fB"fail"\fR
(default for
\fBnamed\-compilezone\fR),
\fB"warn"\fR
(default for
\fBnamed\-checkzone\fR) and
\fB"ignore"\fR.
.RE
.PP
\-m \fImode\fR
.RS 4
Specify whether MX records should be checked to see if they are addresses. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.TP 3n
.RE
.PP
\-M \fImode\fR
.RS 4
Check if a MX record refers to a CNAME. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
\-n \fImode\fR
.RS 4
Specify whether NS records should be checked to see if they are addresses. Possible modes are
\fB"fail"\fR
(default for
\fBnamed\-compilezone\fR),
\fB"warn"\fR
(default for
\fBnamed\-checkzone\fR) and
\fB"ignore"\fR.
.RE
.PP
\-o \fIfilename\fR
.RS 4
Write zone output to
\fIfilename\fR. This is mandatory for
\fBnamed\-compilezone\fR.
.RE
.PP
\-s \fIstyle\fR
.RS 4
Specify the style of the dumped zone file. Possible styles are
\fB"full"\fR
(default) and
\fB"relative"\fR. The full format is most suitable for processing automatically by a separate script. On the other hand, the relative format is more human\-readable and is thus suitable for editing by hand. For
\fBnamed\-checkzone\fR
this does not cause any effects unless it dumps the zone contents. It also does not have any meaning if the output format is not text.
.RE
.PP
\-S \fImode\fR
.RS 4
Check if a SRV record refers to a CNAME. Possible modes are
\fB"fail"\fR,
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.TP 3n
\-o \fIfilename\fR
Write zone output to
\fIfilename\fR.
.TP 3n
.RE
.PP
\-t \fIdirectory\fR
.RS 4
chroot to
\fIdirectory\fR
so that include directives in the configuration file are processed as if run by a similarly chrooted named.
.TP 3n
.RE
.PP
\-w \fIdirectory\fR
.RS 4
chdir to
\fIdirectory\fR
so that relative filenames in master file $INCLUDE directives work. This is similar to the directory clause in
\fInamed.conf\fR.
.TP 3n
.RE
.PP
\-D
Dump zone file in canonical format.
.TP 3n
.RS 4
Dump zone file in canonical format. This is always enabled for
\fBnamed\-compilezone\fR.
.RE
.PP
\-W \fImode\fR
.RS 4
Specify whether to check for non\-terminal wildcards. Non\-terminal wildcards are almost always the result of a failure to understand the wildcard matching algorithm (RFC 1034). Possible modes are
\fB"warn"\fR
(default) and
\fB"ignore"\fR.
.RE
.PP
zonename
.RS 4
The domain name of the zone being checked.
.TP 3n
.RE
.PP
filename
.RS 4
The name of the zone file.

<para>
<command>named-compilezone</command> is similar to
<command>named-checkzone</command>, but it always dumps the
zone contents to a specified file in a specified format.
Additionally, it applies stricter check levels by default,
since the dump output will be used as an actual zone file
loaded by <command>named</command>.
When manaully specified otherwise, the check levels must at
least be as strict as those specified in the

<p><span><strong class="command">dig</strong></span>
(domain information groper) is a flexible tool
for interrogating DNS name servers. It performs DNS lookups and
displays the answers that are returned from the name server(s) that
were queried. Most DNS administrators use <span><strong class="command">dig</strong></span> to
troubleshoot DNS problems because of its flexibility, ease of use and
clarity of output. Other lookup tools tend to have less functionality
than <span><strong class="command">dig</strong></span>.

Although <span><strong class="command">dig</strong></span> is normally used with
command-line
arguments, it also has a batch mode of operation for reading lookup
requests from a file. A brief summary of its command-line arguments
and options is printed when the <code class="option">-h</code> option is given.
Unlike earlier versions, the BIND9 implementation of
<span><strong class="command">dig</strong></span> allows multiple lookups to be issued
from the
command line.

Reverse lookups - mapping addresses to names - are simplified by the
<code class="option">-x</code> option. <em class="parameter"><code>addr</code></em> is an IPv4
address in dotted-decimal notation, or a colon-delimited IPv6 address.
When this option is used, there is no need to provide the
<em class="parameter"><code>name</code></em>, <em class="parameter"><code>class</code></em> and
<em class="parameter"><code>type</code></em> arguments. <span><strong class="command">dig</strong></span>
automatically performs a lookup for a name like
<code class="literal">11.12.13.10.in-addr.arpa</code> and sets the query type and
class to PTR and IN respectively. By default, IPv6 addresses are
looked up using nibble format under the IP6.ARPA domain.
To use the older RFC1886 method using the IP6.INT domain
specify the <code class="option">-i</code> option. Bit string labels (RFC2874)
are now experimental and are not attempted.

The <code class="option">-q</code> option sets the query name to
<em class="parameter"><code>name</code></em>. This useful do distingish the
<em class="parameter"><code>name</code></em> from other arguments.

To sign the DNS queries sent by <span><strong class="command">dig</strong></span> and their

using the <code class="option">-k</code> option. You can also specify the TSIG
key itself on the command line using the <code class="option">-y</code> option;
<em class="parameter"><code>name</code></em> is the name of the TSIG key and

In this case, each <em class="parameter"><code>query</code></em> argument represent an

A global set of query options, which should be applied to all queries,

Non-recursive queries can be made via the <option>-r</option> option.
Setting this option clears the <type>RD</type> &mdash; recursion
desired &mdash; bit in the query which <command>host</command> makes.
This should mean that the name server receiving the query will not
attempt to resolve <parameter>name</parameter>. The

By default <command>host</command> uses UDP when making queries. The

the name server. TCP will be automatically selected for queries that
require it, such as zone transfer (AXFR) requests.

The <option>-t</option> option is used to select the query type.
<parameter>type</parameter> can be any recognised query type: CNAME,
NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified,
<command>host</command> automatically selects an appropriate query
type. By default it looks for A records, but if the
<option>-C</option> option was given, queries will be made for SOA
records, and if <parameter>name</parameter> is a dotted-decimal IPv4
address or colon-delimited IPv6 address, <command>host</command> will
query for PTR records. If a query type of IXFR is chosen the starting
serial number can be specified by appending an equal followed by the
starting serial number (e.g. -t IXFR=12345678).

effectively wait forever for a reply. The time to wait for a response
will be set to the number of seconds given by the hardware's maximum
value for an integer quantity.

<a name="id2543428"></a><h2>DESCRIPTION</h2>
<p><span><strong class="command">host</strong></span>
is a simple utility for performing DNS lookups.
It is normally used to convert names to IP addresses and vice versa.
When no arguments or options are given,
<span><strong class="command">host</strong></span>
prints a short summary of its command line arguments and options.
</p>
<p><em class="parameter"><code>name</code></em> is the domain name that is to be
looked
up. It can also be a dotted-decimal IPv4 address or a colon-delimited
IPv6 address, in which case <span><strong class="command">host</strong></span> will by
default
perform a reverse lookup for that address.
<em class="parameter"><code>server</code></em> is an optional argument which
is either
the name or IP address of the name server that <span><strong class="command">host</strong></span>
should query instead of the server or servers listed in
<code class="filename">/etc/resolv.conf</code>.

When no arguments or options are given,
<span><strong class="command">host</strong></span>
prints a short summary of its command line arguments and options.
</p>
The <code class="option">-a</code> (all) option is equivalent to setting the
<code class="option">-v</code> option and asking <span><strong class="command">host</strong></span> to make
a query of type ANY.
</p>
<p>
<em class="parameter"><code>name</code></em> is the domain name that is to be looked
up. It can also be a dotted-decimal IPv4 address or a colon-delimited
IPv6 address, in which case <span><strong class="command">host</strong></span> will by default

the name or IP address of the name server that <span><strong class="command">host</strong></span>
should query instead of the server or servers listed in
<code class="filename">/etc/resolv.conf</code>.
</p>
When the <code class="option">-C</code> option is used, <span><strong class="command">host</strong></span>
will attempt to display the SOA records for zone
<em class="parameter"><code>name</code></em> from all the listed
authoritative name
servers for that zone. The list of name servers is defined by the NS
records that are found for the zone.
</p>
<p>
The <code class="option">-a</code> (all) option is equivalent to setting the
<code class="option">-v</code> option and asking <span><strong class="command">host</strong></span> to make
a query of type ANY.
</p>
The <code class="option">-c</code> option instructs to make a DNS query of class
<em class="parameter"><code>class</code></em>. This can be used to lookup
Hesiod or
Chaosnet class resource records. The default class is IN (Internet).
</p>
<p>
When the <code class="option">-C</code> option is used, <span><strong class="command">host</strong></span>
will attempt to display the SOA records for zone
<em class="parameter"><code>name</code></em> from all the listed authoritative name
servers for that zone. The list of name servers is defined by the NS
records that are found for the zone.
</p>
Verbose output is generated by <span><strong class="command">host</strong></span> when
the
<code class="option">-d</code> or <code class="option">-v</code> option is used. The two
options are equivalent. They have been provided for backwards
compatibility. In previous versions, the <code class="option">-d</code> option
switched on debugging traces and <code class="option">-v</code> enabled verbose
output.

<em class="parameter"><code>class</code></em>. This can be used to lookup Hesiod or
Chaosnet class resource records. The default class is IN (Internet).
</p>
List mode is selected by the <code class="option">-l</code> option. This makes
<span><strong class="command">host</strong></span> perform a zone transfer for zone
<em class="parameter"><code>name</code></em>. Transfer the zone printing out
the NS, PTR
and address records (A/AAAA). If combined with <code class="option">-a</code>
all records will be printed.

switched on debugging traces and <code class="option">-v</code> enabled verbose
output.
</p>
The <code class="option">-i</code>
option specifies that reverse lookups of IPv6 addresses should
use the IP6.INT domain as defined in RFC1886.
The default is to use IP6.ARPA.

<p>
List mode is selected by the <code class="option">-l</code> option. This makes
<span><strong class="command">host</strong></span> perform a zone transfer for zone
<em class="parameter"><code>name</code></em>. Transfer the zone printing out the NS, PTR
and address records (A/AAAA). If combined with <code class="option">-a</code>
all records will be printed.
</p>
The <code class="option">-N</code> option sets the number of dots that have to be
in <em class="parameter"><code>name</code></em> for it to be considered
absolute. The
default value is that defined using the ndots statement in
<code class="filename">/etc/resolv.conf</code>, or 1 if no ndots
statement is
present. Names with fewer dots are interpreted as relative names and
will be searched for in the domains listed in the <span class="type">search</span>
or <span class="type">domain</span> directive in
<code class="filename">/etc/resolv.conf</code>.
</p>
<p>
The <code class="option">-i</code>
option specifies that reverse lookups of IPv6 addresses should
use the IP6.INT domain as defined in RFC1886.
The default is to use IP6.ARPA.
</p>
The number of UDP retries for a lookup can be changed with the
<code class="option">-R</code> option. <em class="parameter"><code>number</code></em>
indicates
how many times <span><strong class="command">host</strong></span> will repeat a query
that does
not get answered. The default number of retries is 1. If
<em class="parameter"><code>number</code></em> is negative or zero, the
number of
retries will default to 1.
</p>
<p>
The <code class="option">-N</code> option sets the number of dots that have to be
in <em class="parameter"><code>name</code></em> for it to be considered absolute. The
default value is that defined using the ndots statement in
<code class="filename">/etc/resolv.conf</code>, or 1 if no ndots statement is
present. Names with fewer dots are interpreted as relative names and
will be searched for in the domains listed in the <span class="type">search</span>
or <span class="type">domain</span> directive in
<code class="filename">/etc/resolv.conf</code>.
</p>
Non-recursive queries can be made via the <code class="option">-r</code> option.
Setting this option clears the <span class="type">RD</span> &#8212; recursion
desired &#8212; bit in the query which <span><strong class="command">host</strong></span> makes.
This should mean that the name server receiving the query will not
attempt to resolve <em class="parameter"><code>name</code></em>. The
<code class="option">-r</code> option enables <span><strong class="command">host</strong></span>
to mimic
the behaviour of a name server by making non-recursive queries and
expecting to receive answers to those queries that are usually
referrals to other name servers.

</p>
By default <span><strong class="command">host</strong></span> uses UDP when making
queries. The
<code class="option">-T</code> option makes it use a TCP connection when querying
the name server. TCP will be automatically selected for queries that
require it, such as zone transfer (AXFR) requests.

The <code class="option">-4</code> option forces <span><strong class="command">host</strong></span> to only

<span><strong class="command">host</strong></span> to only use IPv6 query transport.

<code class="option">-T</code> option makes it use a TCP connection when querying
the name server. TCP will be automatically selected for queries that
require it, such as zone transfer (AXFR) requests.
</p>
The <code class="option">-t</code> option is used to select the query type.
<em class="parameter"><code>type</code></em> can be any recognised query
type: CNAME,
NS, SOA, SIG, KEY, AXFR, etc. When no query type is specified,
<span><strong class="command">host</strong></span> automatically selects an appropriate
query
type. By default it looks for A records, but if the
<code class="option">-C</code> option was given, queries will be made for SOA
records, and if <em class="parameter"><code>name</code></em> is a
dotted-decimal IPv4
address or colon-delimited IPv6 address, <span><strong class="command">host</strong></span> will
query for PTR records. If a query type of IXFR is chosen the starting
serial number can be specified by appending an equal followed by the
starting serial number (e.g. -t IXFR=12345678).
</p>
<p>
The <code class="option">-4</code> option forces <span><strong class="command">host</strong></span> to only
use IPv4 query transport. The <code class="option">-6</code> option forces
<span><strong class="command">host</strong></span> to only use IPv6 query transport.
</p>
The time to wait for a reply can be controlled through the
<code class="option">-W</code> and <code class="option">-w</code> options. The
<code class="option">-W</code> option makes <span><strong class="command">host</strong></span>
wait for
<em class="parameter"><code>wait</code></em> seconds. If <em class="parameter"><code>wait</code></em>
is less than one, the wait interval is set to one second. When the
<code class="option">-w</code> option is used, <span><strong class="command">host</strong></span>
will
effectively wait forever for a reply. The time to wait for a response
will be set to the number of seconds given by the hardware's maximum
value for an integer quantity.

The <code class="option">-t</code> option is used to select the query type.
<em class="parameter"><code>type</code></em> can be any recognised query type: CNAME,

</p>
The <code class="option">-s</code> option tells <span><strong class="command">host</strong></span>
<span class="emphasis"><em>not</em></span> to send the query to the next nameserver
if any server responds with a SERVFAIL response, which is the
reverse of normal stub resolver behaviour.

.RS 4
Generate DS records for child zones from keyset files. Existing DS records will be removed.
.TP 3n
.RE
.PP
\-s \fIstart\-time\fR
.RS 4
Specify the date and time when the generated RRSIG records become valid. This can be either an absolute or relative time. An absolute start time is indicated by a number in YYYYMMDDHHMMSS notation; 20000530144500 denotes 14:45:00 UTC on May 30th, 2000. A relative start time is indicated by +N, which is N seconds from the current time. If no
\fBstart\-time\fR
is specified, the current time minus 1 hour (to allow for clock skew) is used.
.TP 3n
.RE
.PP
\-e \fIend\-time\fR
.RS 4
Specify the date and time when the generated RRSIG records expire. As with
\fBstart\-time\fR, an absolute time is indicated in YYYYMMDDHHMMSS notation. A time relative to the start time is indicated with +N, which is N seconds from the start time. A time relative to the current time is indicated with now+N. If no
\fBend\-time\fR
is specified, 30 days from the start time is used as a default.
.TP 3n
.RE
.PP
\-f \fIoutput\-file\fR
.RS 4
The name of the output file containing the signed zone. The default is to append
\fI.signed\fR
to the input file.

\-i \fIinterval\fR
.RS 4
When a previously signed zone is passed as input, records may be resigned. The
\fBinterval\fR
option specifies the cycle interval as an offset from the current time (in seconds). If a RRSIG record expires after the cycle interval, it is retained. Otherwise, it is considered to be expiring soon, and it will be replaced.

\fBdnssec\-signzone\fR

.TP 3n
.RE
.PP
\-I \fIinput\-format\fR
.RS 4
The format of the input zone file. Possible formats are
\fB"text"\fR
(default) and
\fB"raw"\fR. This option is primarily intended to be used for dynamic signed zones so that the dumped zone file in a non\-text format containing updates can be signed directly. The use of this option does not make much sense for non\-dynamic zones.
.RE
.PP
\-j \fIjitter\fR
.RS 4
When signing a zone with a fixed signature lifetime, all RRSIG records issued at the time of signing expires simultaneously. If the zone is incrementally signed, i.e. a previously signed zone is passed as input to the signer, all expired signatures has to be regenerated at about the same time. The
\fBjitter\fR
option specifies a jitter window that will be used to randomize the signature expire time, thus spreading incremental signature regeneration over time.
.sp
Signature lifetime jitter also to some extent benefits validators and servers by spreading out cache expiration, i.e. if large numbers of RRSIGs don't expire at the same time from all caches there will be less congestion than if all validators need to refetch at mostly the same time.
.RE
.PP
\-n \fIncpus\fR
.RS 4
Specifies the number of threads to use. By default, one thread is started for each detected CPU.
.TP 3n
.RE

\-N \fIsoa\-serial\-format\fR
.RS 4
The SOA serial number format of the signed zone. Possible formats are
\fB"keep"\fR
(default),
\fB"increment"\fR
and
\fB"unixtime"\fR.
.RS 4
.PP
\fB"keep"\fR
.RS 4

\fB"unixtime"\fR
.RS 4
Set the SOA serial number to the number of seconds since epoch.
.RE

\-o \fIorigin\fR
.RS 4
The zone origin. If not specified, the name of the zone file is assumed to be the origin.
.TP 3n

.RE
.PP
\-p
.RS 4
Use pseudo\-random data when signing the zone. This is faster, but less secure, than using real random data. This option may be useful when signing large zones or when the entropy source is limited.
.TP 3n
.RE

When a previously signed zone is passed as input, records
may be resigned. The <option>interval</option> option
specifies the cycle interval as an offset from the current
time (in seconds). If a RRSIG record expires after the
cycle interval, it is retained. Otherwise, it is considered
to be expiring soon, and it will be replaced.
</para>
<para>
The default cycle interval is one quarter of the difference
between the signature end and start times. So if neither

are specified, <command>dnssec-signzone</command> generates
signatures that are valid for 30 days, with a cycle
interval of 7.5 days. Therefore, if any existing RRSIG records
are due to expire in less than 7.5 days, they would be
replaced.

<term>-j <replaceable class="parameter">jitter</replaceable></term>
<listitem>
<para>
When signing a zone with a fixed signature lifetime, all
RRSIG records issued at the time of signing expires
simultaneously. If the zone is incrementally signed, i.e.
a previously signed zone is passed as input to the signer,
all expired signatures has to be regenerated at about the
same time. The <option>jitter</option> option specifies a
jitter window that will be used to randomize the signature
expire time, thus spreading incremental signature
regeneration over time.
</para>
<para>
Signature lifetime jitter also to some extent benefits
validators and servers by spreading out cache expiration,
i.e. if large numbers of RRSIGs don't expire at the same time
from all caches there will be less congestion than if all
validators need to refetch at mostly the same time.

<p>
<span><strong class="command">dnssec-signzone</strong></span> signs a zone. It generates
NSEC and RRSIG records and produces a signed version of the
zone. The security status of delegations from the signed zone
(that is, whether the child zones are secure or not) is
determined by the presence or absence of a

<p>
When a previously signed zone is passed as input, records
may be resigned. The <code class="option">interval</code> option
specifies the cycle interval as an offset from the current
time (in seconds). If a RRSIG record expires after the
cycle interval, it is retained. Otherwise, it is considered
to be expiring soon, and it will be replaced.

cycle interval, it is retained. Otherwise, it is considered

The default cycle interval is one quarter of the difference
between the signature end and start times. So if neither
<code class="option">end-time</code> or <code class="option">start-time</code>

signatures that are valid for 30 days, with a cycle
interval of 7.5 days. Therefore, if any existing RRSIG records
are due to expire in less than 7.5 days, they would be
replaced.

The format of the input zone file.

This option is primarily intended to be used for dynamic
signed zones so that the dumped zone file in a non-text
format containing updates can be signed directly.
The use of this option does not make much sense for
non-dynamic zones.
</p></dd>
<dt><span class="term">-j <em class="replaceable"><code>jitter</code></em></span></dt>
<dd>
<p>
When signing a zone with a fixed signature lifetime, all
RRSIG records issued at the time of signing expires
simultaneously. If the zone is incrementally signed, i.e.
a previously signed zone is passed as input to the signer,
all expired signatures has to be regenerated at about the
same time. The <code class="option">jitter</code> option specifies a
jitter window that will be used to randomize the signature
expire time, thus spreading incremental signature
regeneration over time.
</p>
<p>
Signature lifetime jitter also to some extent benefits
validators and servers by spreading out cache expiration,
i.e. if large numbers of RRSIGs don't expire at the same time
from all caches there will be less congestion than if all
validators need to refetch at mostly the same time.

listens for resolver queries on a

<p><span><strong class="command">lwresd</strong></span>
is the daemon providing name lookup
services to clients that use the BIND 9 lightweight resolver
library. It is essentially a stripped-down, caching-only name
server that answers queries using the BIND 9 lightweight
resolver protocol rather than the DNS protocol.
</p>
<p><span><strong class="command">lwresd</strong></span>
listens for resolver queries on a
UDP port on the IPv4 loopback interface, 127.0.0.1. This
means that <span><strong class="command">lwresd</strong></span> can only be used by
processes running on the local machine. By default UDP port
number 921 is used for lightweight resolver requests and
responses.

<span><strong class="command">lwresd</strong></span> listens for resolver queries on a

means that <span><strong class="command">lwresd</strong></span> can only be used by
processes running on the local machine. By default UDP port
number 921 is used for lightweight resolver requests and
responses.
Incoming lightweight resolver requests are decoded by the
server which then resolves them using the DNS protocol. When
the DNS lookup completes, <span><strong class="command">lwresd</strong></span> encodes
the answers in the lightweight resolver format and returns
them to the client that made the request.

</p>
<p>
If <code class="filename">/etc/resolv.conf</code> contains any
<code class="option">nameserver</code> entries, <span><strong class="command">lwresd</strong></span>
sends recursive DNS queries to those servers. This is similar
to the use of forwarders in a caching name server. If no
<code class="option">nameserver</code> entries are present, or if
forwarding fails, <span><strong class="command">lwresd</strong></span> resolves the
queries autonomously starting at the root name servers, using
a built-in list of root server hints.
