+ ldns-read-zone reads a zone file, and prints it to stdout, with 1 resource record per line.

+example. 600 IN NS ns2.example.
+example. 600 IN A 123.123.123.123
+
+
+
+
+Again, let's start with including some necessary header files:
+
+\skipline include
+\until errno
+
+In this example, we are going to open a file, if that fails, we'll need errno.h to display an error message.
+
+Okay, let's declare the variables we are going to need today:
+
+\skipline filename
+\until ldns_status
+
+The only two ldns-specific types here are \c ldns_zone and \c ldns_status.
+ - \c ldns_zone is the structure that can contain a complete zone
+ - \c ldns_status again is used to check return values of ldns functions
+
+
+If we get no filename, we'll read standard input, otherwise, we'll try to
+open the given filename:
+\skipline if (argc == 0)
+\until exit(EXIT_FAILURE)
+\until }
+\until }
+
+
+With the \c FILE pointer in our hands, we visit ldns to pour it into a zone
+structure:
+\skipline ldns_zone_new_frm_fp_l
+
+There is also a \c ldns_zone_new_frm_fp, but this one also remembers the
+line number it was on, so we can use that if we encounter a parse error.
+
+Just like in \ref tutorial1_mx, the first argument is a pointer
+to the place ldns should store its creation in, and again, the return value
+is the status code.
+
+The second argument is the file pointer where our zone data should reside.
+
+The third argument, if not NULL, is a \c dname that contains the zones
+origin. It will place this dname after every name in the file that is not a
+fully qualified domain name.
+
+The fourth argument, if not 0, is the default TTL to use.
+
+Both these values can be specified in the zone file by setting \c $ORIGIN and \c $TTL.
+
+The fifth argument specifies the default class, which defaults to IN (\ref LDNS_RR_CLASS_IN).
+
+And finally, every time \c ldns_zone_new_frm_fp_l reads a line from the
+input file pointer, it will increment the value pointed to by the last
+argument with 1.
+
+
+Okay, with that, we should have a nice zone structure. Of course we need to
+check whether it has succeeded.
+
+\skipline LDNS_STATUS_OK
+\until deep_free
+
+If everything went well, we sort the zone if necessary, print it, and free it.
+
+Since \c ldns_zone contains other ldns structures, we use \c ldns_deep_free
+so that every \c ldns_rr_list, \c ldns_rr et cetera are freed too.
+
+\until line_nr);
+\until }
+
+If something went wrong, we use \c ldns_get_errorstr_by_id() to get a nice
+error string instead of just a status integer.
+
+And of course, we should play nice and close the file:
+\skipline fclose
+\until exit

+/**
+ \page tutorial3_signzone Tutorial 3: Signing a zone file
+ \dontinclude ldns-signzone.c
+
+ The full source code can be found in \link examples/ldns-signzone.c \endlink
+
+ Of course, we start by the usual includes. Since we need a bit more here,
+ we'll add those right away.
+
+ \skipline include
+ \until define
+
+ Let's skip the boring usage() and sanity check functions, and dive right
+ into main().
+
+ \skipline main(int argc
+ \skipline {
+
+ We'll be reading another zone file, so let's prepare some variables for that.
+
+ \skipline zone
+ \until argi
+
+ We will create a separate zone structure for the signed zone, so let's have a clear name for the original one.
+
+ \skipline zone
+ \until zone
+
+ To sign a zone, we need keys, so we need some variables to read and store it;
+
+ \skipline key
+ \until status
+
+ The \ref ldns_key structure holds (private) keys. These can be of any
+ supported algorithm type; you can put an RSA key in it, an DSA key, or an
+ HMAC key. Public keys can simply be put in an \ref ldns_rr structure with
+ type \ref LDNS_RR_TYPE_DNSKEY.
+
+ The \ref ldns_key_list type is much like the \ref ldns_rr_list, only, you
+ guessed it, for \c ldns_key entries.
+
+
+ The signed zone will be stored in a new file.
+
+ \skipline file
+ \until file
+
+ And we have some command line options for the output zone.
+
+ \skipline tm
+ \until class
+
+ \c origin is a domain name, so it can be stored in an \ref ldns_rdf
+ variable with type \ref LDNS_RDF_TYPE_DNAME.
+
+ The next part is option parsing, which is pretty straightforward using \c
+ getopt(), so we'll skip this too. U can always look to the source of the
+ file to check it out.
+
+ Okay that's it for the variables, let's get to work!
+
+ First we'll try to read in the zone that is to be signed.
+
+ \skipline fopen(zone
+ \until } else {
+
+ If the file exists and can be read, we'll let ldns mold it into a zone
+ structure:
+
+ \skipline zone_new
+
+ This creates a new (\c new) zone from (\c frm) a filepointer (\c fp),
+ while remembering the current line (\c l) in the input file (for error
+ messages).
+
+ A pointer to the zone structure to be filled is passed as the first
+ argument, like in most \c new_frm functions.
+
+ Like a lot of ldns functions, this one returns a \c ldns_status
+ indicating success or the type of failure, so let us check that.
+
+ \skipline STATUS
+ \until } else {
+
+ If everything is ok so far, we check if the zone has a SOA record and contains actual data.
+
+ \skipline orig_soa
+ \until }
+ \until }
+ \until }
+
+ Now that we have the complete zone in our memory, we won't be needing the file anymore.
+
+ \skipline fclose
+ \until }
+
+ If there was no origin given, we'll use the one derived from the original zone file.
+
+ \skipline origin
+ \until }
+
+ No signing party can be complete without keys to sign with, let's fetch those.
+
+ Multiple key files can be specified on the command line, by using the
+ base names of the .key/.private file pairs.
+
+ \skipline key
+ \until fopen
+
+ As you can see, we append ".private" to the name, which should result in
+ the complete file name of the private key. Later we'll also form the
+ ".key" file name, which will be directly included in the signed zone.
+
+ If the file exists, we'll read it and create a \c ldns_key from its
+ contents, much like the way we read the zone earlier.
+
+ \skipline line_nr
+ \until STATUS
+
+ If this went ok, we need to set the inception and expiration times, which
+ are set in the keys, but will eventually end up in the RRSIGs generated
+ by those keys.
+
+ \skipline expiration
+ \until }
+ \skipline inception
+ \until }
+
+ And now that we have read the private keys, we read the public keys and
+ add them to the zone.
+
+ Reading them from the files works roughly the same as reading private
+ keys, but public keys are normal Resource Records, and they can be stored
+ in general \c ldns_rr structures.
+
+ \skipline FREE
+ \until }
+ \until }
+
+ With \c push() we add them to our key list and our zone. This function
+ clones the data, so we can safely free it after that.
+
+ \skipline push
+ \until free
+
+ And if we're done, we free the allocated memory for the file name.
+
+ \until FREE
+
+ If the reading did not work, we print an error. Finally, we move on to
+ the next key in the argument list.
+
+ \skipline } else {
+ \until }
+ \until }
+ \until }
+
+ Just to be sure, we add a little check to see if we actually have any keys now.
+
+ \skipline count
+ \until }
+
+ So, we have our zone, we have our keys, let's do some signing!
+
+ \skipline sign
+
+ Yes. That's it. We now have a completely signed zone, \c ldns_zone_sign
+ checks the keys, and uses the zone signing keys to sign the data resource
+ records. NSEC and RRSIG resource records are generated and added to the
+ new zone.
+
+ So now that we have a signed zone, all that is left is to store it somewhere.
+
+ If no explicit output file name was given, we'll just append ".signed" to
+ the original zone file name.
+
+ \skipline outputfile
+ \until }
+
+ \c ldns_zone_sign returns NULL if the signing did not work, so we must check that.
+
+ \skipline signed_zone
+ \until } else {
+
+ Writing to a file is no different than normal printing, so we'll print to
+ the file and close it.
+
+ \skipline print
+ \until }
+
+ And of course, give an error if the signing failed.
+
+ \skipline } else {
+ \until }
+
+ Just to be nice, let's free the rest of the data we allocated, and exit
+ with the right return value.
+
+ \skipline free
+ \until }

+QUICK INSTALL GUIDE
+
+drill is a subdirectory in ldns.
+
+To compile drill you need:
+autoreconf && ./configure && make
+
+If ldns is installed in a different location, use --with-ldns=directory
+See also ./configure --help
+
+In the first case you must run drill as:
+LD_LIBRARY_PATH=../.libs ./drill

+REGRESSIONS
+
+This version of drill is based on ldns and as such some things
+are slightly changed. This file documents the changes.
+
+o When tracing (-T option) we use the local resolver (as specified
+ in /etc/resolv.conf) to lookup names. This increases the speed
+ dramatically, but you obviously need to be able to reach a recursive
+ server/cache.
+ Previously drill would try to resolve the names by itself.
+
+o Printing of DSs after DNSKEY records. Because we don't parse our
+ own packets anymore, we cannot print the DS directly after the DNSKEY
+ record. The DSs are now printed AFTER the packet.
+
+o The long options are removed.
+
+o The chase function has a different output, and will be subject to change
+ in the near future.
+
+o The useless (for jokes only) -I option was dropped.
+
+FIXED:
+o the argument parsing is much smarter, the order doesn't matter (much)
+ anymore

+\`configure' configures ldns 1.6.9 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+ --bindir=DIR user executables [EPREFIX/bin]

+.SH NAME
+drill \- get (debug) information out of DNS(SEC)
+.SH SYNOPSIS
+.B drill
+[
+.IR OPTIONS
+]
+.IR name
+[
+.IR @server
+]
+[
+.IR type
+]
+[
+.IR class
+]
+
+.SH DESCRIPTION
+\fBdrill\fR is a tool to designed to get all sorts of information out of the
+DNS. It is specificly designed to be used with DNSSEC.
+.PP
+The name \fBdrill\fR is a pun on \fBdig\fR. With \fBdrill\fR you should be able
+get even more information than with \fBdig\fR.
+.PP
+If no arguments are given class defaults to 'IN' and type to 'A'. The
+server(s) specified in /etc/resolv.conf are used to query against.
+
+.PP
+\fIname\fR
+Ask for this name.
+
+.PP
+\fI@server\fR
+Send to query to this server. If not specified use the nameservers from
+\fI/etc/resolv.conf\fR.
+
+.PP
+\fItype\fR
+Ask for this RR type. If type is not given on the command line it defaults
+to 'A'. Except when doing to reverse lookup when it defaults to 'PTR'.
+
+.PP
+\fIclass\fR
+Use this class when querying.
+
+.SH SAMPLE USAGE
+\fBdrill mx miek.nl\fR
+Show the MX records of the domain miek.nl
+
+.TP
+\fBdrill -S jelte.nlnetlabs.nl\fR
+Chase any signatures in the jelte.nlnetlab.nl domain. This option is
+only available when ldns has been compiled with openssl-support.
+
+.TP
+\fBdrill -TD www.example.com\fR
+Do a DNSSEC (-D) trace (-T) from the rootservers down to www.example.com.
+This option only works when ldns has been compiled with openssl support.
+
+.TP
+\fBdrill -s dnskey jelte.nlnetlabs.nl\fR
+Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY
+record also print the DS record.
+
+.SH OPTIONS
+
+.TP
+\fB\-D
+Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG,
+DS and NSEC) this is \fInot\fR automaticly enabled.
+
+.TP
+\fB\-T
+Trace \fIname\fR from the root down. When using this option the @server and
+the type arguments are not used.
+
+.TP
+\fB\-S
+Chase the signature(s) of 'name' to a known key or as high up in
+the tree as possible.
+
+.TP
+\fB\-V \fIlevel\fR
+Be more verbose. Set level to 5 to see the actual query that is sent.
+
+.TP
+\fB\-Q
+Quiet mode, this overrules -V.
+
+.TP
+\fB\-f \fIfile\fR
+Read the query from a file. The query must be dumped with -w.
+
+.TP
+\fB\-i \fIfile\fR
+read the answer from the file instead from the network. This aids
+in debugging and can be used to check if a query on disk is valid.
+If the file contains binary data it is assumed to be a query in
+network order.
+
+.TP
+\fB\-w \fIfile\fR
+Write an answer packet to file.
+
+.TP
+\fB\-q \fIfile\fR
+Write the query packet to file.
+
+.TP
+\fB\-v
+Show drill's version.
+
+.TP
+\fB\-h
+Show a short help message.
+
+.SS QUERY OPTIONS
+
+.TP
+\fB\-4
+Stay on ip4. Only send queries to ip4 enabled nameservers.
+
+.TP
+\fB\-6
+Stay on ip6. Only send queries to ip6 enabled nameservers.
+
+.TP
+\fB\-a
+Use the resolver structure's fallback mechanism if the answer
+is truncated (TC=1). If a truncated packet is received and this
+option is set, drill will first send a new query with EDNS0
+buffer size 4096.
+
+If the EDNS0 buffer size was already set to 512+ bytes, or the
+above retry also results in a truncated answer, the resolver
+structure will fall back to TCP.
+
+.TP
+\fB\-b \fIsize\fR
+Use size as the buffer size in the EDNS0 pseudo RR.
+
+.TP
+\fB\-c \fIfile\fR
+Use file instead of /etc/resolv.conf for nameserver configuration.
+
+.TP
+\fB\-d \fIdomain\fR
+When tracing (-T), start from this domain instead of the root.
+
+.TP
+\fB\-t
+Use TCP/IP when querying a server
+
+.TP
+\fB\-k \fIkeyfile\fR
+Use this file to read a (trusted) key from. When this options is
+given \fBdrill\fR tries to validate the current answer with this
+key. No chasing is done. When \fBdrill\fR is doing a secure trace, this
+key will be used as trust anchor. Can contain a DNSKEY or a DS record.
+
+.TP
+\fB\-o \fImnemonic\fR
+Use this option to set or unset specific header bits. A bit is
+set by using the bit mnemonic in CAPITAL letters. A bit is unset when
+the mnemonic is given in lowercase. The following mnemonics are
+understood by \fBdrill\fR:
+
+ QR, qr: set, unset QueRy (default: on)
+ AA, aa: set, unset Authoritative Answer (default: off)
+ TC, tc: set, unset TrunCated (default: off)
+ RD, rd: set, unset Recursion Desired (default: on)
+ CD, cd: set, unset Checking Disabled (default: off)
+ RA, ra: set, unset Recursion Available (default: off)
+ AD, ad: set, unset Authenticated Data (default: off)
+
+Thus: \fB-o CD\fR, will enable Checking Disabled, which instructs the
+cache to not validate the answers it gives out.
+
+.TP
+\fB\-p \fIport\fR
+Use this port instead of the default of 53.
+
+.TP
+\fB\-r \fIfile\fR
+When tracing (-T), use file as a root servers hint file.
+
+.TP
+\fB\-s
+When encountering a DNSKEY print the equivalent DS also.
+
+.TP
+\fB\-u
+Use UDP when querying a server. This is the default.
+
+.TP
+\fB\-w \fIfile\fR
+write the answer to a file. The file will contain a hexadecimal dump
+of the query. This can be used in conjunction with -f.
+
+.TP
+\fB\-x
+Do a reverse loopup. The type argument is not used, it is preset to PTR.
+
+.TP
+\fB\-y \fI\fR
+specify named base64 tsig key, and optional an algorithm (defaults to hmac-md5.sig-alg.reg.int)
+
+.TP
+\fB\-z \fR
+don't randomize the nameserver list before sending queries.
